Space shuttle Atlantis lands at Kennedy following the successful STS-132 mission to the International Space Station.

The goal of 3-D printing is to take this capability to microgravity for use on the International Space Station. In space, whatever astronauts have available on orbit is what they have to use -- but just like on Earth, parts break or get lost. When that happens, there's a wait for replacement parts, ...

The non-profit B612 Foundation aims to build, launch, and operate the first privately funded deep space mission—a space telescope in orbit around the Sun that will map the inner Solar System in search of asteroids that could impact Earth.

A Soyruz rocket launched NASA's Scott Kelly and two Russian cosmonauts into space for what will be a year-long mission aboard the International Space Station. It is NASA's first-of-its-kind study of identical twins to learn more about how long-term spaceflight affects the human body — by sending one

How big can they get? What's the largest so far detected? Where does an 18 billion solar mass black hole hide? We've never seen them directly, yet we know they are there. Lurking within dense star clusters or wandering the dust lanes of the galaxy. Where they prey on stars. Or swallow planets whole....

Have you ever wondered why some telescopes are launched into space while others are built on remote mountain tops? What is actually the best for astronomy? Here we provide a ringside view of the fight for the elusive photons from deep space - is it a battle of the telescope giants?

As 2015 comes to a close we look back at an exciting year of reaching new heights and revealing the unknown for the benefit of humankind.

The first American woman in Space talks about her historic flight on NASA's 50th anniversary. She flew aboard Space Shuttle Challenger in June 1983 on the STS-7 mission.
