On its final flyby of Saturn’s largest moon in 2017, NASA’s Cassini spacecraft gathered radar data revealing that the small liquid lakes in Titan’s northern hemisphere are surprisingly deep, perched atop hills and filled with methane.
NASA and its International Space Station partners have set a new schedule and new crew assignments that will include the first flight of NASA astronaut Jessica Meir, an extended stay for NASA astronaut Andrew Morgan, and a record-setting flight for NASA astronaut Christina Koch.
When plants take in too much energy, they don’t get fat — they lighten up. They absorb more sunlight than they need to power photosynthesis, and they get rid of the excess solar energy by emitting it as a very faint glow.
Former astronaut and long-duration spaceflight pioneer Owen Garriott, 88, died on Monday at his home in Huntsville, Alabama.
NASA is working right now to send American astronauts to the surface of the Moon in five years, and the agency has its sights set on a place no humans have ever gone before: the lunar South Pole.
A Northrop Grumman Cygnus spacecraft scheduled to liftoff on April 17 carries supplies and scientific experiments to the International Space Station.
Results from NASA’s landmark Twins Study, which took place from 2015-2016, were published Thursday in Science. The integrated paper — encompassing work from 10 research teams — reveals some interesting, surprising and reassuring data about how one human body adapted to — and recovered from — the extreme environment of space.
A new kind of atomic clock, non-toxic propellant system and missions to characterize how space weather interferes with satellites and communication transmissions are one step closer to liftoff. With the second-ever SpaceX Falcon Heavy launch complete, these NASA technologies await the powerful rocket’s next flight.
Smart spacesuits and solar surfing may sound like the stuff of science fiction, but they are just two of the technology concepts NASA has selected for further research as part of the NASA Innovative Advanced Concepts (NIAC) program.
NASA is a step closer to returning astronauts to the Moon in the next five years following a successful engine test at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
For five months in mid 2017, Emily Mason did the same thing every day. Arriving to her office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, she sat at her desk, opened up her computer, and stared at images of the Sun — all day, every day.
Parker Solar Probe has successfully completed its second close approach to the Sun, called perihelion, and is now entering the outbound phase of its second solar orbit.
A small asteroid has been caught in the process of spinning so fast it’s throwing off material, according to new data from NASA’s Hubble Space Telescope and other observatories.
Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour — so fast it could travel the distance between Earth and the Moon in just 6 minutes.
NASA Television and the agency’s website will provide live coverage of the fifth meeting of the National Space Council starting at 1 p.m. EDT Tuesday, March 26.
In 1989, NASA’s Voyager 2 zipped past Neptune—its final planetary target before speeding to the outer limits of the solar system. It was the first time a spacecraft had visited the remote world.
A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid’s surface.
This fuzzy orb of light is a giant elliptical galaxy filled with an incredible 200 billion stars.
Two astronauts switched their spacesuits to battery power this morning at 8:01 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last about six-and-a-half hours.
Happy equinox, Earthlings! March 20 marks the spring equinox, one of two seasonal markers in Earth’s year-long orbit when the Sun appears to shine directly over the equator, and daytime and nighttime are nearly equal lengths–12 hours–everywhere on the planet.
