Why are scientists trying to grow organs at the International Space Station? People live on Earth not in zero-gravity. A stem cell expert explains why it is useful to do these experiments in space.
Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.

When it comes to commercial space tourism, suborbital flight are the first frontier. But what are the risks? Are there health requirements? What should you know before taking such a way-out trip?
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.

SpaceX’s launch of astronauts to the International Space Station will make it the first private company to launch humans to space. The effort has ramifications for NASA and spaceflight in general.
Over the last 50 years, a lot has changed in rocketry. The fuel that powers spaceflight might finally be changing too.

Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
Asteroid Ryugu photographed from a distance of about 12 miles (20 kilometers) looks just gray and bland, but a close-up provides more color.

It is a pretty spectacular achievement to not only rendezvous with an asteroid as it is whizzing around the Sun but also collect a sample. Here’s what the researchers learned.

Tomanowos, aka the Willamette Meteorite, may be the world’s most interesting rock. Its story includes catastrophic ice age floods, theft of Native American cultural heritage and plenty of human folly.
Governments and corporations must get serious about the legal, technical, economic, social and ethical implications of a potential space-based resource economy.
