University of Florida scientists used lunar soil collected during Apollo 11, 12 and 17 missions to successfully grow plants from seed. It's a first in human history and could help future space colonists grow food on the moon.
Soon, one out of every 15 points of light in the night sky will actually be a satellite, not a star.
If our living space is to become outer space, we have a lot of challenges to address. And our first line of defense will be space architects.

Amazon CEO Jeff Bezos and his brother plan to blast into space next month. But even if you're not related to a billionaire, you can still experience the fun of space at a 'down-to-Earth' price.
Other companies, like Amazon and Telesat, are planning to emulate StarLink's model, meaning there could soon be as many as 50,000 satellites, mostly for the purpose of internet service, floating around in space.
A Russian cosmonaut printed some steak in space, and now we're one step closer to sending humans to Mars.
We've been cruising to and from the International Space Station since 2000. Isn't it about time we started moving on to other space destinations and establishing human outposts?
The moon's getting a new, space-proof library that will serve as an archive for all humanity.
By studying these geological formations here on Earth, we may be able to learn how to live on other planets.
Astronauts will be testing human and bull sperm to see how microgravity might affect future human reproduction in space.
Can you imagine living on Mars? It's hard for some, but HowStuffWorks founder Marshall Brain has a new book that discusses the idea in depth.

Imagine if we could get to Mars in 40 days instead of seven months! It could happen if we used plasma rockets, which travel at 34 miles per second. But how do we make this a reality?
Researchers looked at the sea urchin jaw's uniquely powerful structure to build a better excavation tool, with the aim of digging on Mars — or beyond.
We've figured out pretty much how to grow them. It's the making them safe for consumption that could be tricky.
Radiation is a serious occupational risk for astronauts. An active shielding approach currently being developed for spacecraft could greatly diminish that risk.

If we ever want to start cruising this vast universe, we're going to need some different ports of call along the way. What and where are they?
In the future, as we send space probes and manned missions to explore the solar system and possibly colonize other worlds, there's a major problem that we'll have to overcome -- keeping in touch with them.
Every day in space is like finals week, only the consequences of failing are substantially worse. So how far might we be willing to go to conquer the great unknown? Would you make a good candidate?
If we're going to get serious about boldly going where no man has gone before, and send humans beyond the solar system, we're gonna need a cheap and plentiful energy source to help us get there.

Forget about curb appeal. This cosmic fixer-upper requires some serious renovations before we can start living on it. So how serious are we talking? And are they going to happen in our lifetime?

Whether we head there to mine some helium-3 or take the first steps in expanding humanity's reach into the solar system, we want to go to the moon -- permanently. When's that going to happen?

Surely nuclear weapons, which can obliterate entire cities, contain enough destructive power to blow a giant space rock to bits, right? What does NASA make of the whole explosive business?
Imagine parallel parking on slippery ice during a dangerous dust storm. Landing on Mars presents similar obstacles, on a grander scale. And remember, insurance doesn't cover extraterrestrial damage.
Researchers are using the moon's gravitational pull on bodies of water to test underwater turbine electricity production. It's considered clean power, but is it completely safe?
By Josh Clark
It's safe to assume there won't be a moon colony any time soon. But it's still a tantalizing thought. But wouldn't it be cool to be able to live, vacation and work on the moon?
