Long-term moon missions could pose "substantial risks" to astronauts from space radiation, according to a study.

"Everything this helicopter does will be a first-time event," said NASA engineer Nagin Cox.

The rover will use its suite of scientific instruments to search for signs of ancient microbial life on the red planet.

The Trump administration is charting a new course for America's future in space.

The Tianwen-1 spacecraft is scheduled to arrive on the red planet in February, 2021.

Comet NEOWISE comes once every 6800 years, here's how you can use this sighting as an opportunity to learn more about space travel and exploration.

America needs a plan to cement itself as the dominant power in space.

NASA said bonus points will be awarded for designs that can capture the vomit of sick crew members without them having to put their head in the toilet.

The NASA Headquarters in Washington D.C. has a new name, announced by the space agency Wednesday, which honors Mary Jackson.

The first crewed launch from American soil in nearly a decade was postponed on Wednesday due to stormy weather.

This is the final flight test for the SpaceX's next-generation Crew Dragon spacecraft.

Space is not a relic of the Cold War—it continues to be a great pursuit of mankind.

Next week, NASA astronauts Doug Hurley and Bob Behnken will conduct the first manned orbital spaceflight launched from American soil since the end of the shuttle program.

The Crew Dragon Demo-2 mission will mark the first time that American astronauts have launched from U.S. soil into orbit since the end of the Space Shuttle Program in 2011.

Locals in the village of Mahounou in Côte d'Ivoire have found what appears to be a long metal pipe that reportedly fell from the sky.

"We realize there will be impacts to NASA missions, but we understand that our top priority is the health and safety of the NASA workforce," said the space agency's administrator, Jim Bridenstine.

The rover will search for signs of past microbial life on Mars, while also investigating the planet's climate and geology.

"These selected missions have the potential to transform our understanding of some of the solar system's most active and complex worlds," NASA's Thomas Zurbuchen said.

During the mission, Koch took part in what was the first all-female spacewalk alongside NASA astronaut Jessica Meir.

Fixing problems on Voyager is a tricky business given that it is currently located around 11.5 billion miles from Earth.

Lunar regolith—dust, soil, broken rock and related materials found on the moon's surface—actually consists of between 40-45 percent oxygen.

Aldrin, alongside fellow Apollo 11 crew member Neil Armstrong, touched down on the lunar surface at 8:17 p.m. UTC on July 20, 1969.

Every giant leap begins with one small step, and we've identified a step that is critical for lunar exploration and settlement.

NASA released a "treasure map" of water ice buried close enough to the surface of mars for potential astronauts to "dig up" with a shovel.

The dummies are fitted with more than 5,600 sensors each, which will measure exposure to space radiation.

Hibernation technology may enable mission designers to reduce spacecraft mass by around a third.

The Exploration Extravehicular Mobility Unit builds on the designs of spacesuits currently used by astronauts when they conduct spacewalks outside the International Space Station.

The Mars 2020 mission is scheduled to launch in July 2020, and it is expected to reach the red planet in February 2021.

The building was constructed as a facility to quarantine astronauts and the material they brought back from the moon during the Apollo program.

"The LightSail 2 mission is a game-changer for spaceflight and advancing space exploration," said Bill Nye, whose Planetary Society funded the project.
