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.

Black holes in the center of the Milky Way Galaxy.

Scientists have known for a long time that there's a Supermassive Black hole in the center of the Milky Way Galaxy. But, now they've found a lot more small black holes and they guesstimate that there might be as many as 10,000 more small black holes in the center of the Milky Way Galaxy.
The way most most Supermassive Black holes form is by "eating" other black holes, stars and other things. Everything that the black hole consumes adds more mass to it and the black hole grows. The more it eats,  the bigger the black hole becomes. Most black holes start out as small ones. Then they suck things in it and they become bigger.
The way they form in the first place is:
A giant star runs out of Hydrogen and other forms of fuel. It collapses and what's left over is a black disk that has an immeasurable amount of mass. In fact, according to Einstein, a black hole might have an infinite amount of mass. However,  I find that hard to believe, because it sounds impossible for anything to literally have infinite mass.
The Sun is a Medium star. It doesn’t have enough mass to form a black hole. Scientists measure other stars, black holes and other really large objects in space with.   "Solar. Masses". One solar mass is the mass of the Sun.
In order to form a black hole, a star has to be at least 5 solar masses.
There are a few black holes that Scientists have found which they think are Millions or Billions of solar masses. These are called: Supermassive Black holes. There is one in the center of every spiral galaxy, including the Milky way.
The gravity from these Supermassive black holes helps hold the galaxies together.
Scientists are not sure exactly how Supermassive black holes form. However, one reason might be that it could of consumed Thousands of other black holes and planets and kept getting bigger.
The gravity from a black hole is so strong that almost nothing can escape from it. Even if something traveled at the speed of light, it would not be able to escape from the gravitational pull of a black hole. That is why they are hard for Scientists to find.
However,  Stephen Hawking discovered a type of radiation that does manage to escape from black holes. Since he discovered it, this radiation was named: Hawking radiation. Astronomers need special, X-ray telescopes to see it.
This technology is so new, that until recently, nobody had ever actually seen a black hole. They knew they existed, because they could see stars, planets and other things getting sucked into them. Hopefully, with the newer, X-ray telescopes, Scientists will actually be able to get a picture of a black hole for the first time ever! Astronomers have been talking about trying to do that this year (2018).
