Boeing is back in the business of human spaceflight after its uncrewed CST-100 Starliner passenger spacecraft successfully docked with the International Space Station (ISS) at 8:28 pm EDT, fulfilling the key objective of Orbital Flight Test-2 (OFT-2).

The 45-year-old Voyager 1 deep space probe is showing its age as NASA engineers try to determine why it is sending back invalid telemetry data from its attitude control system as it hurtles through interstellar space, never to return.

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.

On its third attempt, Boeing's CST-100 Starliner spacecraft reached Earth orbit today. At 6:55 pm EDT, the uncrewed passenger capsule launched from the Cape Canaveral Space Force Station in Florida atop a United Launch Alliance Atlas V rocket.

It looks as though NASA's InSight Mars lander's days are numbered after the space agency announced that the spacecraft is gradually losing power due to dust building up on its solar panels, already reducing their output by 90 percent.

To keep the lights on in NASA's Artemis human lunar outpost, Sandia National Laboratories is developing electrical micro-grids to handle the power distribution from the Moon base's mini nuclear reactors to the various living and support facilities.

eVTOL makers say these electric air taxis will be so much quieter than helicopters that they'll be able to put hundreds of them in the air without annoying city residents. Well, let's see – Joby Aviation and NASA have released acoustic test figures.

Scientists working on NASA's James Webb Telescope have reached an important milestone, completely aligning the space observatory's massive mirrors, enabling it to capture in-focus images with all onboard instruments.

On April 19, the one-year anniversary of its first flight, NASA's Ingenuity Mars helicopter visited and took images of the crash site of the protective aeroshell and parachute that helped deliver it and the Perseverance rover to the Red Planet.

NASA and partners are developing backpack-sized technology for future Moon explorers that will allow them to map and navigate the lunar surface in the darkness of the high polar regions to within a centimeter without GPS.

Evidence is mounting that the key building blocks of life may have been delivered to our home planet from space. Scientists have now identified in meteorites the last two DNA nucleobases that hadn’t yet been found in extraterrestrial samples.

NASA’s InSight lander has recorded the two strongest quakes detected so far on Mars, with both measuring over magnitude 4. These seismic events rolled in from the far side of the Red Planet, and one also clocked the record for longest marsquake.
