NASA's Artemis 1 rocket, the Space Launch System, reached the Kennedy Space Center's Launch Complex 39B on Friday. The successor to the Apollo program could one day send humans back to the moon.
In 2016, Musk said that a "meaningful number of people" could reach the red planet in 10 years. Now, he seems to predict a crewed Mars landing in 2029.
Picture perfect: Mission managers say the telescope's mirror segments have been aligned and have focused on single stars, a critical milestone, and the telescope is working flawlessly.
Astronauts hammered collection tubes into the lunar surface on the last Apollo mission to the moon. Now a sample is being carefully pierced open — to be analyzed by today's latest tech.
Critics, including the National Park Service, said exploding rockets after launch could rain fiery debris onto surrounding land, including a federally protected wilderness.
The mission, which had been set for this year, is a part of the ExoMars program to search for signs of life on Mars. It's likely to be delayed by nations' response to Russia's invasion of Ukraine.
Since touching down in Jezero Crater, NASA's Perseverance rover has already cached 6 samples that could one day be brought back to Earth. Astrobiologists hope they hold signs of past microbial life.
While you're sky-gazing, look to the western horizon. Jupiter will be setting there as evening twilight ends. And that bright star? That's Regulus, part of the Leo constellation.
Astronomers noticed it was unlikely the piece of space junk was from the Falcon 9 launch in 2015, due to the gap between the rocket's trajectory and object.
The James Webb Space Telescope has seen its first starlight, but its 18 mirror segments aren't yet perfectly aligned. As a result, the pictures it's sending back now aren't exactly cosmic eye candy.
SpaceX's Elon Musk said Thursday that the first orbital flight of his towering Starship could come soon. NASA plans to use the fully reusable Starship to land astronauts on the moon as early as 2025.
The satellites that can't maintain orbit will burn up as they reenter Earth's atmosphere, SpaceX says. A geomagnetic storm hit the day after they were launched.
A satellite has detected massive leaks of methane, a powerful greenhouse gas, from natural gas plants and pipelines. Most of these releases are deliberate, resulting from sloppy pipeline repairs.
NASA says the International Space Station will stop operating at the end of 2030. After that, the space agency plans to crash the football field-sized craft into a remote part of the Pacific Ocean.
