NASA lost its ability to launch humans from U.S. soil when the space shuttle retired. Now, companies and billionaire entrepreneurs are defining a new space age.

An international team of astronomers say they have not directly detected life, but that the presence of phosphine can only be explained by living microbes.

In a tweet, NASA Administrator Jim Bridenstine wrote that the agency “is buying lunar soil from a commercial provider! It’s time to establish the regulatory certainty to extract and trade space resources.”

The directive comes as space is increasingly viewed as a war-fighting domain.

Boeing has completed 75 percent of 80 corrective actions needed after a test of its Starliner spacecraft went awry last year.

Astronauts Bob Behnken and Doug Hurley talk about their plunge through the Earth's atmosphere to a soft landing in the Gulf of Mexico.

After years in which NASA seemed like an afterthought in the national consciousness and was at the back of the line when the federal budget was allocated, the space agency appears to be on a roll.

NASA astronauts Doug Hurley and Bob Behnken have completed a successful splashdown in the Gulf of Mexico off the coast of Pensacola, Fla., aboard the SpaceX Dragon Endeavour capsule.

It will be the first landing ever by astronauts in the gulf, according to Jonathan McDowell, astronomer at the Harvard-Smithsonian Center for Astrophysics. The crew undocked from the station at 7:35 p.m. Saturday and is scheduled splash down Sunday at 2:48 p.m.

If all goes according to plan, NASA astronauts Bob Behnken and Doug Hurley will climb aboard their SpaceX Dragon spacecraft, and undock from the station at about 7:34 p.m. Saturday and splashdown at about 2:42 p.m. Sunday.

The rover has a drill for obtaining rock cores and soil samples, which it will stash in containers that in the future could be sent back to Earth for study in laboratories.

On Tuesday, Virgin Galactic showed off the inside of the spacecraft it calls SpaceShipTwo, a sleek crew cabin for six passengers and two pilots that is scheduled to carry its first paying passengers perhaps by the end of the year.

The number of satellites in space is expected to balloon as private companies launch hundreds of new ones, raising the issue of which federal agency should track them.

Bob Behnken and Doug Hurley have been floating around on the International Space Station for about a month and are now contemplating their return home.

One of the “Hidden Figures,” Jackson helped promote women and minorities at the agency.

NASA announced that it is well on its way to transforming the International Space Station into a commercial hub.

After a top NASA official improperly contacted a senior Boeing executive about its bid to win a contract potentially worth hundreds of millions of dollars, Boeing tried to change its bid, alarming NASA officials.

Mars and Earth are only on the same side of the sun every 26 months, meaning NASA has a limited window to launch the spacecraft to the Red Planet.

NASA awarded the contract, worth nearly $200 million, to a Pittsburgh-based company as part of a program to hire private-sector companies to deliver cargo and science experiments to the lunar surface.
