What are some good things that we've gotten out of the Space Program:

Hubble has shown the world Trillions of things that are too far away to see with a regular, backyard telescope.
NASA invented Velcro and a ton of things we use everyday.
The International Space Station (ISS) brought several countries together to work on a very big, expensive, Scientific project. We have made a lot of Scientific discoveries in Chemistry, Physics, Biology, Geography, Astronomy and other branches of Science and Math on the ISS.
It's very expensive to launch a rocket into space. NASA has to spend over 1 Billion dollars every time they launch a rocket. That is money that goes to companies and people all over the US and the rest of the world. That's "trickle down economics".
NASA and other space agencies have proven from space that the world is not flat. Scientists can watch the weather from space. They can spot hurricanes, tornadoes, Tsunamis and other things long before they can harm anyone. They can see lightning hitting Earth. They have discovered that lightning actually strikes Earth between 50-100 times per second!
They have sent spacecraft's to every single planet. They learned that all the gas giants (Jupiter, Saturn, Uranus and Neptune have rings around them. The only one you can see with a regular telescope at home is Saturn's ring.
They've discovered signs of possible life on Mars and a few moons in the Solar system, but no proof yet.
They've put military satellites in space, as well as others for GPS, Astronomy, Geology, Google Earth, Weather, Earth's atmosphere, and other things.
They've sent signals to other planets, in hopes of aliens intercepting the signals a Million light years away. They are also listening for signals from aliens.
Metiors and other things are headed toward Earth. NASA wants to find a way to stop them from hitting us and preventing a mass extinction of humans. (That's what killed the dinosaurs.)
If we are no longer able to live on Earth, we must find somewhere else to go.
The government has set off nukes in space for Scientific and military purposes. (Maybe nukes can be used to save Earth from being hit with a Metior.)
A lot of new technology had to be invented to build rockets powerful enough to get humans to space and be able to survive up there. New, advanced technology had to be invented to communicate with Astronauts from the ground.
Voyages I and II are in interstellar space, going far away from Earth. They now know how big the Heliosphere is.
The temperature of space is close to Absolute Zero. Scientists have done experiments on the Space Station to get even closer to Absolute Zero than the temperature of space. They can get closer to that temp on the ISS than they can on Earth.
They have talked about sending regular civilians like you and me to space for vacation. I'd love to go up, but, it will be too expensive.
Scientists know the appropriate size and composition of all the planets.
Probes have been sent to Venus. They landed on the surface and they stopped working within a few hours. Probably because it's so hot that they all may have melted or the acid rain may have damaged them as well. Either way, NASA knows that they can never send humans up there.
Spy satellites have been sent up for military purposes over countries like Iraq. They also have some over the US for: Military, law enforcement and Science. (Who knows, the government of the US and other countries might be watching you right now!)
It is really a lot of fun to watch a rocket launch.
There's a lot of things that were built Thousands of years ago which nobody can figure out how to replicate them and build them the same way today, including the Great Pyramids. They probably had help from aliens.
Some of the Pyramids line up perfectly with Orion's belt.
This is only scratching the surface of all the good things that have come from the Space Program.

Jupiter.

The Earth would fit inside Jupiter 1324 times! It may not appear to be that much bigger than Earth, but, the way someone described it to me was: Because of the mass of Jupiter, it would be like a balloon, the planet would stretch , just like a balloon. Just like a balloon stretching to hold more water or anything else you put in it, Jupiter would, THEORETICALLY, stretch whenever you put something inside of it. It would stretch out enough to where All the other planets, including Pluto, would fit inside of it!
The famous, Great Red Spot is about Three times bigger than Earth.
It is a large storm that's been going on for over 300 years. It is currently, slowly shrinking. It spins counterclockwise at about 225 MPH (360 KPH). It is comparable to a hurricane.
Jupiter would fit inside the Sun 9 times.
It has a faint ring system. Scientists did not know about the rings until the Voyager Spacecraft got there. Voyager showed the rings for the first time. The rings are too faint to be seen with a Telescope. In fact, I have a really powerful Telescope and I can't see the ring with it. University of Central Florida in Cocoa, FL has the second largest Telescope in the state of FL and they can't see it with that scope.
It has, as of now, 69 confirmed Moons. Probably, more to be found.
Looking through my Telescope, I can see the color bands on the planet and Six of it largest Moons.
Since, Galileo invented his own Telescope and looked at Jupiter, and discovered 4 of these same Moons (Io, Europa, Ganymede & Callisto), they are called: Galileo Moons. Those are Jupiter's largest moons. The rest are too small to see from Earth.
(Unfortunately, someone else invented the Telescope, just a short period of time before Galileo invented his telescope. So, he can't claim credit for inventing it.)
There are some very violent storms on Jupiter. Mostly inside the planet. Lightning on this planet is much more powerful than what we experience here on Earth. Scientists believe that it rains Diamonds inside of Jupiter. Because of the heat and pressure inside of the giant ball of Gas. But, they can't prove it.
The composition of the planet is mostly: Hydrogen, Helium and Ammonia. It's believed to have a rocky and metallic core.
Since the planet spins so fast, it completes one rotation in 9.8 Earth hours.
The rapid rotation causes Jupiter to bulge at the Equator. The diameter at the Equator is: 88,846 Miles (142,948 K).
The diameter at the poles is: 83,082 Miles (133,708 K). The Scientific name for this shape is: An Oblate Spheroid.
Jupiter is a Brown Dwarf. A failed star. Since it is made up of the same elements as most stars. However, it would have to be 75 times more massive to cause nuclear fusion of Hydrogen and turn into a star.
The color bands around Jupiter are created by strong 400 MPH (640 K) winds flowing East to West in the planets upper atmosphere.
Jupiter has a huge magnetic field, larger than any other planets. It is also the strongest magnetic field in our Solar System. It's almost 20,000 times strong than the one here on Earth! It is more than 1,000 times the lethal dose of radiation for a human. This magnetic field damages every spacecraft that goes near it, even if it is heavily shielded. The magnetic field extends out between 600,000 - 2 Million Miles (1 Million - 3 Million  K) towards the Sun and forms a tail which extends over 600 Million Miles (1 Billion K) behind the planet.
At it's furthest point from the Sun Jupiter is 507.04 Million Miles away.
When it's closest to the Sun it's 460.24 Million Miles away.
It orbits the Sun at a speed of 29,205 MPH. Completing one rotation around the Sun in 11.86 Earth years.
The distance from Jupiter to Saturn depends on where they are in orbit. When they are on the same side of the Sun and at their closest point, they are approximately 5 Astronomical Units (AU) away from each other.
When they are on opposite sides of the Sun, they are about 15 AU away from each other.
(One AU is the average distance between the Sun and Earth. 93 Million Miles or 149,668,992 K).
Depending on where the Earth and Jupiter are in their orbits, Jupiter is between 4.2 and 6.2 AU away from Earth.
We are lucky to have a planet the size of Jupiter in our Solar System, because, being so big, it has a lot of gravity. It attracts a lot of Metiors and other things to it. So, rather than hitting Earth or the other planets, a lot of them hit Jupiter instead.
Imagine what might have happened if Shoemaker-Levy would of hit Earth.
The SL comet had been captured by Jupiter's gravity about 20 or 30 years before it broke into several large pieces and hit Jupiter in July of 1994. The fragments of the comet got too close to the planet on July 16, 1994. The first impact created a fireball larger than Earth! A total of 21 impacts were observed over the next six days. The largest one created a dark spot more than 7,456 Miles (12,000 K) across. The explosion it created was 6 Million Megatons of TNT. That's 600 times the worlds entire known nuclear arsenal at that time, according to: www.americaspace.com.
A comet or meteor that size hitting Earth would quickly put an end to all life on Earth! In fact, most Scientists believe that it was a large meteor that crashed into Earth 65,000,000 years ago that killed off the Dinosaurs.
