Space is the area beyond the Earth’s atmosphere. It includes all the vast universe. We try to explore the universe as much as we can, but to no avail. Space is huge and really wide. We could not explore it all, no matter how hard we try. However, that does not mean we will stop trying.
We even discovered some space facts that can come in handy. Here are a few simple space facts especially, for kids to help you know more about space and what it is that we discovered so far. So, before you consider living in space, you should know some of these space facts.
Space is very cold. It is -270.45 Celsius. So, space suits are insulated to keep the astronauts warm in the cold conditions. A space suit absorbs body heat and when the body needs warmth, it will release heat. However, a full NASA space suit costs $12,000,000.
The second fact is that space is silent. There is no way for sound to travel through space. So, astronauts communicate using their radios. If you want to start your space training as an astronaut, here are a few facts for you from space training facts:
One million Earths can fit inside the sun. The Earth has more trees than the stars in the Milky Way. Since we are talking about space facts, we should also mention some sun facts in space for kids as well: The sun mass takes up 99.86% of the solar system.
The sun is a star. Stars are balls of hot gases. Mainly, hydrogen. Hydrogen is burned due to the pressure causing it to turn into helium. Which makes the star shine really bright. Space is huge and full of all different kinds of things.
It is vast and full of wonders. So, let us learn some fun facts about space together! On LearningMole.com. We need to explore how space was created first. Scientists came up with different theories about space creation. They did not all agree on one theory.
How was It created?
It is mostly believed that it all started with the Big Bang theory. However there are more than one theory that talks about space creation. We will concentrate on three theories. First is the Big Bang theory. Second is the Steady State theory. Third is the Plasma Universe theory. We will also learn more facts about space, especially for kids.
The Big Bang theory
The first theory is the Big Bang Theory. 13 billion or 15 billion years ago, all the matter and energy in the known cosmos were crammed into a tiny point. In fact, according to this theory, matter and energy back then were the same thing. It was impossible to distinguish them apart.
Scientists who believed in the Big Bang believed that this small but incredibly dense point of primitive matter/energy exploded. Within a small period of time the fireball ejected matter/energy at velocities approaching the speed of light.
At some later time, maybe seconds later and maybe years later, energy and matter began to split apart and become separate entities. All of the different elements in the universe today developed from what spurt out of this original explosion.
Big Bang theorists claim that all of the galaxies, stars, and planets still retain the explosive motion of the moment of creation and are moving away from each other at great speed. This came from an unusual finding about our neighboring galaxies.
In 1929 Edwin Hubble, working at the Mount Wilson Observatory in California, announced that all of the galaxies he had observed were receding from us, and from each other, at a high speed. Meaning, they are getting further and further away.
The Big Bang Theory supposes that the world started out from a small point that exploded. That explosion caused the elements and matter as we know it to come into existence. Up till this moment in time the explosion is still causing galaxies to move away from each other.
The Steady State Theory
However, people were not satisfied with the Big Bang theory so they came up with another theory called the Steady State theory. According to the Big Bang theory, the universe is always expanding since it is moving away from each other. On the other hand, the Steady State proposes that new matter emerges in the empty space that is left from the expansion.
How can we get matter from nothing? Well, the answer is simple. According to the fundamental law of physics of the conservation of matter, matter can neither be created nor destroyed, but only converted into other forms of matter.
However, the discovery of quasars proposed the universe might be changing. Quasars are small points of light that give off enormous amounts of radio energy. The astronomers could not find the quasars that formed recently.
The Plasma Universe Theory
People were skeptical about the second theory of creation and so they proposed a third theory of creation. The third theory is the Plasma Universe Theory. This theory was proposed by a Swedish plasma physicist. He noted that 99% of all observable universe is made of plasma.
Plasma is an ionized gas that conducts electricity and is sometimes called the fourth state of matter. This theory proposes that the Big Bang never happened and that the universe is crossed by giant electric currents and huge magnetic fields. In the Plasma Universe, galaxies come together slowly over a much greater time span than in the Big Bang theory.
Perhaps taking as long as 100 billion years. Computer simulations of plasmas subjected to high-energy fields reveal patterns that look like simulated galaxies. Using actual electromagnetic fields in the laboratory, researchers have also been able to replicate the plasma patterns seen in galaxies.
10 facts about space for kids
There are many theories out there, but the mostly accepted theory is the Big Bang theory. Meanwhile, let us check our 10 quick facts about space for kids, before moving onto what space consists of. The first fact is that for a rocket to get into orbit around Earth, it needs to travel 17,600 miles per hour.
The second fact is about the first people that have been to space. The first person on the moon was Neil Armstrong. Whereas, the first person in space was Yuri Gagarin. The third fact is that our solar system contains 8 main planets. Fourth is that the longest time an astronaut has spent in space is 437 days. Fifth is that in an observable universe there are an estimated 2 trillion (2,000,000,000,000) galaxies.
Sixth is that the International Space Station is the largest ever crewed object in space. Seventh is that spacecraft have visited all the known planets in our solar system. Eighth is that the Moon has a number of precious metals such as gold and silver.
Ninth is that the strongest thing in the universe are explosions that are generated beams of high-energy radiation called gamma-ray bursts (GRBs). They are considered by astronomers to be the most powerful thing in the universe. Tenth is that those gamma-ray bursts have about the same amount of energy in 10 trillion a trillion billion megaton bombs!
What does it consist of?
Now that we learned some interesting facts about space for kids, let us explore what space consists of together. The universe is full of many interesting things. First of which is the meteors. Meteors are meteoroids that fall through Earth’s atmosphere at a high speed.
Meteoroids are fragments or debris in space that resulted from collisions among other asteroids, comets, moons, and planets. They are small space rocks. However, we can still see them when they fall through the Earth’s atmosphere in the form of meteors or meteor showers.
The pressure and heat they generate as they push through the air causes them to glow and create a light streak in the sky. They are made up of rock and metal. They burn up mostly before touching the ground. We call them shooting stars. It is estimated that about 48.5 tons (44,000 kilograms) of meteoritic material falls on Earth each day.
Meteor Showers are several meteors falling through the Earth’s atmosphere. It happens when the Earth passes by particles left by comets. When those particles enter the Earth’s atmosphere, they burn up and create streaks of light in the sky as well.
We love to watch meteor showers. Numerous showers happen annually as Earth’s orbit takes it through the same patches of comet debris. According to NASA, this year’s Orionid meteor shower peaks on Oct. 21.
The second thing that space contains is comets. Comets orbit the sun. They contain icy pieces of frozen gases, rock, and dust in their center that we call the nucleus. When the comet comes closer to the sun, it heats up and blows dust and gases. That forms a giant ball around its nucleus and two tails.
That ball is called a coma. The tails are made of dust and excited gas. The solar wind, which is the constant flow of particles from the sun, pushes them miles away from the sun. The known number of comets in the solar system is 3,535.
Comets are leftover material from the formation of the universe long ago. Scientists believe that some of the Earth’s resources could have been delivered by comets. The third thing we will mention is asteroids.
Asteroids are rocky worlds that orbit our sun. They are also leftovers from the universe formation long ago. They can be as big as a car or a city. They contain rock, metal, carbon, or rubble piles held together by gravity.
Mostly, found in the main asteroid belt. This vast, doughnut-shaped ring between the orbits of Mars and Jupiter contains hundreds of thousands of asteroids, maybe millions. They follow different orbits and may end up entering the Earth’s atmosphere.
Scientists believe that asteroids as well may have been the source of resources on Earth. In addition to believing they hide the secrets of the past of the universe. The fourth topic we will discuss is meteorites. Meteorites are any of the previous objects if they survive the trip through the Earth’s atmosphere.
In the first known case of an extraterrestrial object to have injured a human being in the U.S., Ann Hodges of Sylacauga, Alabama, was severely bruised by an 8-pound (3.6-kilogram) stony meteorite that crashed through her roof in November 1954.
Fifth topic we will discuss is the dwarf planets. According to NASA, dwarf planets are massive bodies that are shaped by gravity into a round or nearly round shape. They don’t have enough of their own gravitational muscle to clear their path of other objects as they orbit the Sun. There are five well- known dwarf planets.
In our solar system, dwarf planets are mostly found in the Kuiper Belt beyond Neptune; Pluto is the best-known example. The largest object in the asteroid belt is the dwarf planet Ceres. Like Pluto, Ceres shows signs of active geology, including ice volcanoes.
Ceres is named for the Roman goddess of corn and harvests. Ceres has lots of water. Ceres is 25% of the asteroid belt’s total mass. Pluto is 14 times more massive than Ceres. Ceres is the largest object in the asteroid belt between the orbits of Mars and Jupiter.
Ceres was the first asteroid discovered, on 1 January 1801 by Giuseppe Piazzi at Palermo Astronomical Observatory in Sicily. Ceres has the ability to support life, however, it also supports some other interesting, earth-like features.
The surface of the planet remains geologically active, mainly through means of volcanic activity. Eris is the most massive, however. It is the second-largest known dwarf planet in the Solar System. It’s about the same size as Pluto, but is three times farther from the Sun. A year on Eris is 558 years of Earth.
As for Haumea, it is a dwarf planet located beyond Neptune’s orbit. Billions of years ago, a large object may have collided with the body, knocking most of the surface ice away and imparting a rapid spin to Haumea.
The spin, in turn, elongated Haumea into its unusual shape. The moons of Haumea may have once been part of its surface, forming much like Earth’s moon did after a collision. Haumea was discovered in 2003. This dwarf planet has an extremely elongated shape, with its longest dimension being about 1,218 miles long (1,960 km).
Haumea rotates very rapidly and has the shortest day of all the dwarf planets, only 3.9 hours. Like the other dwarf planets in the Kuiper belt, Haumea is actually very cold. It’s colder than -240 degrees, which means that it’s probably frozen on the outside.
The Kuiper Belt is a disc- shaped region beyond Neptune. It extends for about 55 times the distance between the Earth and the Sun. It contains hundreds of thousands of icy bodies, comets, Pluto, Eris, Sedna, Quaoar, Makemake, Haumea, and asteroids. All of which may have been there for millions of years ago.
Makemake is another dwarf planet in the outer solar system. It was the fourth body identified as a dwarf planet, and was one of the bodies that caused Pluto to lose its status as a planet. The discovery team used the codename “Easter bunny” for the object, because of its discovery shortly after Easter.
According to space capsule facts, it is believed that all of the objects orbiting in the Kuiper Belt are space capsules of the previous million years of ice entities. Finally, we will conclude with some space facts for kids. It is mainly, 5 facts about space for kids, before moving onto some fun space concepts.
5 facts about space for kids
These 5 facts are a must to know before deciding to live in space according to living in space facts for kids. They are also considered some of the coolest space facts for kids. First fact is that there is a difference between a Meteoroid, a Meteorite, and a Meteor.
A meteoroid can be small as a speck of dust or as big as an asteroid. A meteorite is a meteoroid that enters the Earth’s atmosphere and reaches the surface of the Earth without burning up in the sky. If it burns up before reaching the Earth’s surface, we call it a meteor. The second fact is that there are scars on the moon.
The Earth and the moon are hit by asteroids or meteors all the time. The Earth has tsunamis, erosions, earthquakes and volcanic eruptions that erase evidence of past impacts. Whereas, the moon does not have an atmosphere to erase such evidence and so it has scars. The third fact is that rotation causes day and night.
The Earth rotates around the sun in an invisible axis. The Earth takes 24 hours to make one complete rotation. Therefore, a day is 24 hours long. The day and night depend on which side is facing the sun. The side that faces the sun has daytime. Whereas, the side facing away from the sun has nighttime.
The fourth fact is that a dog has gone to space. Yes! A dog went to space. The first object to enter space made by humans was launched by a Russian satellite. It had a homeless dog named Laika. Laika was the first dog to enter space, but unfortunately passed away in orbit. The satellite could not make it back to Earth.
The fifth and final fact from space exploration facts for kids is that over 90% of the Universe Is Still Undiscovered. Cool, isn’t it!
Concepts related to Space
After these 5 interesting facts about space for kids, let us begin our journey in exploring concepts related to space. For example, gravity. We will learn more about gravity using gravity facts for kids.
The Four Fundamental Forces of Nature are Gravity, The weak force, Electromagnetism, and The strong force. Gravity is the weakest of these four forces. Gravity is essential for life on Earth and the universe. Let us explore some gravity in space facts for kids.
Without Gravity, the Earth and universe will no longer be as we know them to be. Anything that has matter generates Gravity. Gravity pulls things together. The larger an object is, the stronger the gravitational force is.
Even a person has gravity, but it is not strong enough to pull things into their orbit. Whereas, a planet has enough gravity to pull objects into its orbit. A star, on the other hand, has enough gravitational force to pull a whole solar system into its orbit, like our sun.
Gravity is what keeps the moon in place. The moon orbits the Earth. That means that it circles Earth without crashing into it or floating away. The reason the Moon can do this is the gravitational pull of our planet.
Gravity causes tides of the ocean because it is made of matter. The moon has a gravitational pull that causes the tides. It is still not strong enough to pull the Earth. The ocean reacts to the pull of the moon by receding and coming back with the ebb and flow of the tide. The sun causes some tides as well.
Sir Isaac Newton is the mathematician who discovered the force of gravity and formulated the Universal Law of Gravitation. It all goes back to the story of the apple that fell on his head. We, humans, need gravity to live. Without gravity, everything will go off floating into space. Gravity keeps the Earth in place, not too far or too close to the sun. So, we are not freezing or burning.
Gravity and weight are not the same, however. In space an astronaut is weightless, but with 90% gravity similar to that on Earth. For example, take a scale and put it in the elevator as you stand on it, you will notice weight changes but gravity is still the same.
Gravity makes waves that travel at the speed of light. So, if something were to happen to the sun, the gravitational effect would reach us at the same time as the light from the event. Gravity might be carried by massless particles called gravitons. The hypothetical particles for quantum gravity are those gravitons.
3 Basic space facts
Let us move onto some interesting Galaxy facts. But before doing so, we will first take a quick peek at some basic space facts for kids. These facts are so much fun, it is hard to get enough of them. First fact is that the Milky Way is always moving.
According to facts about the Milky Way in space for kids, the Milky Way is the galaxy in which our solar system lies. The Earth revolves around the sun. The Sun revolves around the center of the Milky Way. The Milky Way is a part of the Local Group of galaxies that is always moving as well, approximately 600 km/s or 2.2 million km/hr.
The second fact is that there is a planetoid similar to the Earth. It is called Sedna. Sedna is an asteroid that is referred to as a planetoid because it shares similar features with the Earth. It is considered a dwarf planet. One year on it is 10,500 years on Earth.
The third and final fact, before moving onto our fun Galaxy facts is that there is a possibility of life on Mars. In 1986, NASA found fossils of microscopic living beings in a rock. Now, it is time for our fun Galaxy facts!
Fun Galaxy facts for kids
A Galaxy is a massive and gravitationally bound system that contains different entities. For example, stars, gas, dust, dark matter, and compact stars. A dark matter is the result of the gravitational effects that appear to be a result of some invisible mass. The word galaxy is derived from the Greek word galaxias which literally means “milky”.
Galaxies can range in size from a dwarf with as few as ten million stars to massive giant galaxies with a hundred trillion stars. Each star orbits its galaxy’s own center of mass and it is estimated that there are more than 170 billion galaxies in the observable universe.
According to international space center facts for kids, it is believed that all large galaxies contain massive black holes at their centers. Most galaxies are between 10 billion and 13.6 billion years old. Our universe is about 13.8 billion years old. Small dwarf galaxies can have as few as ten million stars, while large galaxies can have hundreds of trillions of stars.
In 1926, Edwin Hubble created the Hubble sequence, a morphological classification scheme for galaxies. The three classifications in the Hubble sequence are Elliptical galaxies, Spiral Galaxies and Lenticular Galaxies.
An elliptical galaxy has a smooth, featureless light distribution and appears as ellipses in photos. A spiral galaxy is a flat, rotating disc with stars, planets, dust and gases. It gets its name from the ongoing star formations in the spiral structures extending from the galactic disc.
A lenticular galaxy has a bright bulge at the center and is surrounded by a disk-like structure. An irregular galaxy has no distinct shape. It is usually small. The Milky Way Galaxy is a spiral galaxy. It contains our solar system.
Therefore, galaxies are divided apart based on their appearance. Most galaxies are dwarf galaxies. The closest galaxy to the Milky Way is Andromeda, which is around 2.6 million light years away from us. It takes over two hundred million years for the sun to orbit the center of the galaxy. This is called a galactic year. Some galaxy examples are:
The Andromeda Galaxy is a spiral galaxy. It will collide and merge with our Milky Way Galaxy in the future. The Black Eye Galaxy is a spiral galaxy as well. It is known as the Evil Eye Galaxy. It has a dark band that is absorbing dust in front of its bright nucleus.
The Sombrero Galaxy is a lenticular galaxy. It has a dark dust lane and bulge that gives it a similar appearance to a sombrero hat. The Whirlpool Galaxy is a spiral galaxy. It has the visual appeal of a whirlpool, like water going down a drain.
One- third of all the known galaxies are elliptical galaxies. There are two types of elliptical galaxies. Giant elliptical galaxies are formed when small galaxies merge. Dwarf elliptical galaxies are smaller galaxies than the giant elliptical ones.
In spiral galaxies, young stars are found in the spiral arms of the spiral galaxy while older stars are found around the galactic center. Spiral galaxies can be either normal or barred. Normal spiral galaxies have arms that run from the center. Whereas, barred spiral galaxies have bars across the center. Their arms are found at the ends of the bar and not at the center.
The lenticular galaxies look like lenses. They fall between elliptical and spiral galaxies categorization. They have rotating disks of stars with no spiral arms. Any other galaxy that does not fall into the categorizations we mentioned is an irregular galaxy. Their irregular shape is due to the gravitational force of the other galaxies.
Facts about international space
Let us explore some more facts about space for kids before moving onto our next topic of black holes in space facts for kids as well. These facts help us know our space and solar system better. The universe is so vast and so we will learn about it step by step.
First fact is that we cannot hear normally in space because sound travels through a medium. There is no atmosphere in space and so sound will have no medium to travel through. Second fact is that there are two invisible planets. Uranus and Neptune are invisible to our naked eye. So, we need an advanced telescope to locate them.
The third and final fact before we start on with black holes is that black holes cause spaghettification. When anything enters a black hole in space it is pulled and ripped apart, like a spaghetti. This is why there can be no life in black holes.
Black holes can be found in space and at the center of a galaxy. John A. Wheeler coined the term “black hole” in 1967. Black holes swallow anything and everything close to them. Almost every galaxy has a black hole in its galactic center. Even the Milky Way has a black hole at its galactic center.
They are very powerful and can even absorb light. It is believed that they are remnants of massive stars, like the sun, that have died. There are three types of black holes. They are primordial, stellar, and supermassive black holes.
A primordial black hole is a black hole that was formed shortly after the Big Bang. A stellar black hole is created by the collapse of a progenitor. A progenitor is the object left over after a massive star collapses at the end of its life cycle.
A supermassive black hole (SMBH) is a very massive black hole found at the center of galaxies. Our Milky Way galaxy has a supermassive black hole in its center. It’s located in Sagittarius A (Sgr A*). It is about 26,000 light-years from our Solar System.
Black holes are actually invisible. We cannot see a black hole because they absorb everything and anything, including light. We know they exist by observing the objects surrounding them. Event horizon is the boundary surrounding a black hole. The object cannot escape once it crosses the event horizon.
A black hole is the mass of several million suns. They die with time and evaporate, returning their energy to the universe. The death of a star leads to it becoming a stellar black hole in space. The first black hole was discovered using X- Ray Astronomy. The fourth type of black holes is miniature black holes.
In the Milky Way, it is estimated that there could be ten million to a billion black holes because of the huge number of stars in the galaxy. In space there is no light between stars and planets. So, no light reaches our eyes and we see black space.
Now that we know all of this information about black holes in space, let us learn some more facts about space before jumping onto our next stop in this exciting space adventure. These facts are from the shortest space facts for kids. However, make sure to check our space facts for kids’ videos on LearningMole.com.
Space facts for kids
The first fact is that the International Astronomical Union (IAU) downgraded Pluto from our ninth planet to a dwarf planet in 2006. The second fact is that Mars has lower gravity than Earth. A person that weighs 200 pounds on Earth would only weigh 76 pounds if they stood on Mars.
The third fact is that our sun is thought to be an average-sized star and yet one million Earths could fit inside the sun. The fourth fact is that NASA’s findings show strong evidence that Mars might have liquid water. The final fact in this section is that Earth is hit by an asteroid around the size of a car around once per year. Thankfully, most of it burns up in the atmosphere before it hits land.
We are at our last stop in this exciting space adventure. We will explore different inventions that flew into space, like space missions that were launched and carried out in space, Rocket ships, space shuttles, and satellites. We will learn simple and fun facts about each while discussing space facts in between as we have been doing.
Space missions are carried out to explore the vast universe one step at a time. Some missions involve an astronaut, but others do not. Some missions are just carried out for the purpose of taking pictures and spying on an object in space. Other space missions are for infinite exploring purposes.
There are four types of space adventures that we will discuss. The first type is the flyby space mission. A flyby space mission is when a spacecraft passes by a celestial object but is not held in orbit by it. The spacecraft just passes by it while taking pictures and recording information about the celestial body and sends the information it collected back to Earth.
A flyby space mission is intended for quick exploration of a celestial body. However, once it passes the body it cannot go back to explore the interesting aspects or to further explore the body. The second type of space missions is the orbiter space missions.
The orbiter space mission is intended to orbit the object and collect more detailed information about the objects in space. It takes pictures, uses heat sensors, records information, and films videos of the object and sends all of these pieces of information back to Earth. Which enables scientists to study it further and understand its nature.
Third is the rover space mission. The rover space mission is when the spacecraft actually touches the surface and lands on the celestial object it is exploring. It swabs samples to bring back to Earth to be analyzed and collects information in a more involved manner. Finally, the fourth type is human space exploration.
A human astronaut is sent on the spacecraft to explore the celestial object up close and collect information to bring back to Earth to be analyzed by scientists. They take notes of any strange sightings, explore the nature of the object up close, and record any form of activity they find. All of which is later analyzed by the scientists on Earth.
Human space exploration helps address questions about the universe, the history of it, and our place in it. So that, we can advance our technology, inspire new fields of study, and make a connection with all the other nations and living beings out there if there is any.
The most famous space mission was Apollo 11. All this talk about space missions makes you want to be an astronaut and go on a mission yourself. Astronauts need to have a master’s degree, usually in a STEM field.
You must also complete two years of training and pass the hard NASA physical examination. Those interested in space can find jobs not only as astronauts, but also as scientists, engineers, or astronomers. So, now that we know all about space missions, let us learn some more quick space facts before moving on.
Space travel facts for kids
The first fact is that the first woman to enter space was Valentina Tereshkova in 1963. The second fact is that the first private citizen, millionaire Dennis Tito, toured space in 2001. He paid $20 million to spend a week in space. The third fact is that one space shuttle launch costs $450 million.
The fourth fact is that the Russian space craft, Luna 2, landed on the moon in 1959. It crashed at high speed. Fortunately, it was an unmanned craft with no astronauts inside. The fifth fact is that astronauts on the International Space Station get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects in space.
Rocket ship facts
Now that we know some more about space, let us know more about the rocket ships that carry us through space. Rockets are pushed forward using the exhaust from their engines. A rocket can reach a speed of 15,000 miles per hour in as little as eight minutes.
A rocket cannot escape Earth’s gravity and make it into space. However, it can if it’s traveling at least 7 miles per second. A rocket ship beats the vacuum of space. Rockets were first used as weapons. Rocket power is measured in thrust.
The first rocket in space was launched by Germany in 1942. They were invented in China, more than 800 years ago. The first rockets were simple. They were made out of a cardboard tube packed with gunpowder and attached to a guide stick. Similarly, the fireworks we use today. You can even make a rocket at home.
There are four systems in a rocket. The structural system, the payload system, the guidance system, and the propulsion system. The structural system, or frame, is similar to that of an airplane.
Rockets take off by burning fuel. Burning fuel produces gas as a byproduct. Which escapes the rocket with a lot of force. The force of the gas escaping provides enough thrust to power the rocket upwards. It escapes the force of gravity pulling it back to Earth.
3 Quick Space Facts
Now that we know a lot about rocket ships, we will explore some space facts together before moving onto our next topic. The first fact is that even in an airplane, a trip to Pluto will take about 800 years. The second fact is that Neptune’s days are 16 hours long. Finally, it takes eight minutes and 19 seconds for light to travel from the sun to Earth.
Space shuttle facts for kids
Moving onto our next topic, space shuttles have so many secrets. Let us learn about them together. According to space shuttle facts for kids, space shuttles are the first reusable aircraft ever. Space rockets cannot be used more than once, however a space shuttle can be sent off to space over and over again.
The first launched space shuttle was in 1981. The name of the shuttle was Columbia. In 2011, NASA retired the space shuttles. The last shuttle was Atlantis on July 21st, 2011. NASA launched a total of 6 space shuttles.
The space shuttles were Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavour. Space shuttles take off like a rocket and land like a plane. There went on a total of 135 missions. A space shuttle could carry 8 astronauts at a time. Therefore, about 355 astronauts flew on space shuttles.
A space shuttle is made of 3 parts. The orbiter is the first part. It is the place where the crew would live and do their work. It can also carry things to space. The second part is the external tank. It is full of fuel and is attached to the orbiter. It helps launch the orbiter. The final and third part is the boosters. It provides a push in the first two minutes of launching.
If you want to see a space shuttle in real life, make sure you visit a museum which is where they are now located. Let’s learn some more about space before carrying on. The first fact is about Venus.
Simple Space Facts to remember
Venus is the hottest planet. Venus has temperatures over 450 degrees. The second fact is about the sun. The sun is made up of three quarters of hydrogen and helium. The third fact is about the mass of the moons. If you added up the mass of all of the moons in our solar system it would be less than 0.1% of the mass of the Earth. Now let us move onto our final stop.
We will discuss some fun satellite facts for kids, share some more space facts with you, and then we will conclude our journey. A satellite is a small object orbiting a larger object. There are natural satellites and artificial satellites.
Natural satellites are like the moon orbiting the Earth. Mercury and Venus are the only planets that do not have a natural satellite. Most artificial satellites in space are launched into space by rockets. The artificial satellites mainly gather information about the object they orbit.
The first artificial satellite was launched by the Soviet Union into orbit in 1957. Satellites are launched into space annually to orbit around all different planets of our solar system. Satellites have different purposes and types.
Some satellites are for spying purposes like the military satellites. Others are for transforming and sending signals through mobile phones, televisions, radio, and internet. Those are called communication satellites. Some scientific satellites orbit the Earth to clearly see the sky better than any telescope would ever allow us to.
Other satellites are called space stations and are used by astronauts. There are also satellites to navigate through the sky and the seas by using an airplane or a ship. In addition to the GPS which is widely used to navigate the different routes that lead to the desired destinations. And so, the different types of satellites are:
• Communications Satellite
• Remote Sensing Satellite
• Navigation Satellite
• Geocentric Orbit type satellites – LEO, MEO, HEO
• Global Positioning System (GPS)
• Geostationary Satellites (GEOs)
• Drone Satellite
• Ground Satellite
• Polar Satellite
• Nano Satellites, CubeSats and SmallSats
Satellites are made of aluminum and titanium. Titanium is hard and so it is used along with its alloys in the manufacture of satellites. A satellite consists of three parts. The first part is the communications system. It is responsible for transmitting and receiving signals and it contains the antennas.
The second part is the power system. It includes solar panels that provide power. Finally, the propulsion system. It includes rockets that propel the satellite. A satellite can also include a payload in order to collect information.
Satellites travel at 18,000 miles per hour. That means in a given day, satellites can travel the entire circumference of the Earth about 14 times. There are 2500 satellites in orbit around the Earth.
Space facts for kids
Now that we know all about satellites, let us learn some quick easy facts for kids about space. The first fact is that when you are on Mars, the sunset looks blue. The second fact is that Neutron stars are the smallest stars there could be. They are created when the core of a star collapses after a supernova explosion.
The third and final fact is that in our solar system, the planets are named after the mythological Greek and Roman gods. Stay tuned and keep checking our amazing website material on LearningMole.com.
Conclusion of Our Adventure
Our space adventure has come to an end and it is time we shout out a big goodbye! We learned all about space together and explored different theories of how the universe came into existence. We explored facts about the Big Bang theory, the Steady State theory, and the Plasma Universe theory.
We also investigated what it consisted of. We learned all about Meteors, Comets, Asteroids, Meteorites, and the Dwarf Planets. All of which included interesting facts about space. Then, we came to our next stop which was space concepts. We explored the concept of gravity, galaxy, and black holes.
