NASA has finalized the payloads for its first cargo deliveries scheduled to be carried by commercial lunar landers, vehicles created by companies the agency selected to take part in its Commercial Lunar Payload Services (CLPS) program. In total, there are 16 different payloads, which consist of a number of difference science experiments...

Nearly one month ago, Boeing completed the first orbital test flight of its Starliner spacecraft with a near-perfect landing at White Sands Space Harbor in New Mexico. The mission had to be cut short due to a well-publicized timing error that delayed the spacecraft's service module from performing an orbital insertion burn. This caused the thrusters on board the service module, which provides power to Starliner during most of its mission, to fire longer than expected.

To prove it is safe for astronauts, the company will test its Crew Dragon capsule’s rescue system.

Elon musk He seems to be quite focused on Starship at this time, sharing photos of the work being done on the Starship orbital prototype designed "SN1", which is currently being built at the SpaceX facility in Boca Chica, Texas. The CEO answered a series of questions on Twitter Thursday night, providing more details about Starship and how it will eventually work to achieve Musk's goal of turning humans into an interplanetary species with a colony on Mars.

European researchers are working on a system that can churn out breathable oxygen from simulated samples of moon dust. “Being able to acquire oxygen from resources found on the Moon would obviously be hugely useful for future lunar settlers, both for breathing and in the local production of rocket fuel,” explained Beth Lomax, a chemist from the University of Glasgow, in an European Space Agency (ESA) press release.

After months of anticipation, SpaceX's new crew-worthy spacecraft, Crew Dragon, is finally prepped for its last major test before astronauts can begin using it for rides to the International Space Station. But finding the right weather conditions could be a roadblock this weekend.

Starship, SpaceX’s ambitious rocket under development, could have an underestimated effect on society’s interactions with space. The stainless steel rocket is currently in the prototyping phase, but when complete it’s set to unlock some of SpaceX’s most ambitious targets. It offers a fully-reusable design, which could drop launch prices lower than ever to $20,000 per ton. It uses easier-to-harvest rocket fuel, which could create a planet-hopping network to the moon...

SpaceX's Crew Dragon astronaut taxi successfully fired its launch-escape engines on the ground today (Nov. 13) at the company's facilities at Cape Canaveral Air Force Station, keeping the vehicle on target for a crucial flight test in the coming weeks.

It sounds like the famed astrophysicist would rather Elon Musk spent less time thinking about Cybertrucks and more time making Star Trek real. Could SpaceX and Tesla founder Elon Musk become a real-life Zefram Cochrane, the fictional inventor of warp drive on Star Trek? Astrophysicist and science personality Neil deGrasse Tyson seems to think so.

Both SpaceX and Boeing are part of NASA's Commercial Crew Program, which aims to bring astronaut launches back to US soil for the first time since the end of the space shuttle era in 2011. SpaceX already successfully sent an uncrewed Crew Dragon capsule to the ISS earlier this year. Boeing was hoping to match SpaceX's achievement, but a glitch caused Starliner to use up too much fuel. Instead of meeting up with the ISS, Starliner will attempt to come back to Earth early.

2019 was the shot. 2020 is the chaser.

ThumbSat aims to make access to space for the scientific community a much more affordable endeavor.

Spacewalks have become a regular feature of life in the International Space Station, but they are still a risky adventure. By Jason Caffrey.

For the second time in less than three years, a spacewalk outside of the International Space Station has been cut short because of a water leak in an astronaut's helmet. A spacewalk involving NASA astronaut Tim Kopra and British colleague Tim Peake was called off about 2 hours early today (Jan. 15) when Kopra noticed some water inside his helmet.

Astronaut ice cream — did it really fly? Vox's Phil Edwards investigates, with the help of the Smithsonian and an astronaut.

There are only few places in the world where rockets lift off. That short list will get a little longer on Tuesday, when Russia plans to open a new gleaming gateway to orbit. The Vostochny (Eastern) Cosmodrome should officially enter service with the launch of a Soyuz rocket scheduled for 10:01 p.m. EDT on April 26. The first mission from a brand new launch pad will deliver three satellites into the Earth's orbit—and it could deliver much more than that.

SpaceX has successfully landed another Falcon 9 rocket after launching the vehicle into space this evening from Cape Canaveral, Florida. Shortly after takeoff, the vehicle touched down at SpaceX’s Landing Complex 1 — a ground-based landing site that the company leases at the Cape. It marks the second time SpaceX has pulled off this type of ground landing, and the fifth time SpaceX has recovered one of its rockets post-launch. The feat was accomplished a few minutes before the rocket's second stage successfully put the company's Dragon spacecraft into orbit, where it will rendezvous with the International Space Station later this week.

NASA is working on sending a submarine into the depths of the Kraken Mare — the largest ocean on Saturn’s moon Titan. There are really two big reasons why we want to go to Titan. Number one: “to determine if hydrocarbon based life is possible on Titan,” said Jason Hartwig, a NASA cryogenics engineer, in a presentation at the NASA Innovative Advanced Concepts Symposium in Raleigh on Wednesday.

The so-called EmDrive creates thrust by bouncing microwaves around in an enclosed chamber, and uses only solar power - and now a Nasa lab is set to reveal its findings on the technology.

New results on the controversial, “impossible” EmDrive propulsion system could be soon published in a prestigious peer-reviewed scientific journal, according to credible rumors. “It is my understanding that Eaglework’s new paper has been today accepted for publication in a peer-review journal, where it will be published,” said high-reputation poster José Rodal, Ph.D, on the NasaSpaceFlight forum, which is often the primary source of updates for all things EmDrive. “Congratulations to the Eagleworks team!” The poster added that the sources of the leak are not employed by NASA.
