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.

What if NASA offered you a chance to go to Mars? Would you go?

DO YOU WANT TO GO TO MARS?
A lot of people, including myself, really love outer space. But, do you really want to go there? Probably not!

If NASA called you and gave you the chance to be one of only a dozen people to go on the first trip to Mars, would you go?
It sounds cool. I have always wanted to go to outer space. That would be so awesome to spend one day in space. If, it only took a few hours to get to Mars, that would be cool to.
But, be careful what you wish for, because, you might get your wish!
On the space station, they recycle water. In other words, the water they use to flush the toilet gets filtered and cleaned. Then it goes back into a tank and the Astronauts drink that water! Then, they pee it out into the toilet, it gets filtered again, goes back into the holding tank and repeats the process over and over again! Yuck!
They lose muscle mass, because, in almost 0 gravity, you don't get to work your muscles very much. They have to exercise 2 hours a day to prevent muscle loss.
Food doesn't taste the same in space as it does on Earth.
What would you do if you can out of food or if the food you have with you spoiled or rotted and it was no longer safe to eat? The nearest grocery store is about 35,000 miles away, on Earth.
It is a very small space on a rocket, space shuttle or the ISS. It would get boring up there in those cramped quarters. If there is someone up there with you that you don't get along with, that would suck for you! It will take about 5 or 6 months to get to Mars with today's technology. You'll be on the planet for probably 6 months to a year, then a 6 month long trip back to Earth. All that time, you'd be with someone you hate!
The closest Doctor to you will be on Earth! If you get sick or injured, you are on your own. You will be able to call the Doctor on Earth and talk to him, but, he can't give you any prescription medication, stitch up a wound, put a cast on a broken bone, perform surgery or anything like that!
Mars is much smaller than Earth. That means there will be less gravity. That will have an affect on your weight, the amount of pressure and stress on your Spine, how you walk and other things. Astronauts have no stress on their spine on the International Space Station. In fact, while their in space, their spine stretches out and the Astronauts are about an inch or two taller in space. After 6 months, they come back to Earth and the Earth's gravity pulls their spine down and puts stress on it again. That causes back pain.
There are a lot of dust storms up there. The wind blows the Red, Iron Oxide all around and it will be hard to see. The wind might even blow you around as well. You will be much lighter on Mars than on Earth.
(The surface of the planet is made up of Iron Oxide, which is basically rust from iron, just like on a car. That's what gives Mars it's red color.)
You'll have to wear a space suit everywhere you go. You might get a hole in your suit, which you can't just fix with duct tape. You could also run out of Oxygen or have problems with your O2 tank. Either one of those things: a hole in your suit or problems with your Oxygen, would be life threatening.
It is very cold and dusty up there on Mars. The atmosphere doesn't stop Metiors or harmful UV Ray's, Gamma Ray's, X Ray's, and other harmful things from space as well as the Earth's atmosphere does.
If your space ship breaks down, there's no one there to fix it and no way for it to be fixed. You would never make it back home to Earth.
I am sure you'd have to sign a waiver before you went to Mars, saying you know all the risks you're taking and if anything happens to you your family can't sue!
On the bright side, you would die famous. You would always be known as one of the first people to ever land on Mars. NASA would probably name a satellite after you, your birthday might become a national holiday, people would write books and movies about you and your name would be as famous as Neil Armstrong, Galileo, Stephen Hawking and Edwin Hubble.
