WASHINGTON — NASA’s embrace of reused rockets continued with an agreement this month to switch the upcoming launch of an Earth science satellite from a new to a previously flown Falcon 9, a change whose full terms remain proprietary.
Russia’s war with Ukraine has created an existential crisis for NASA. Three decades ago, NASA embraced international cooperation as a rationale for the International Space Station (ISS). Now, the same argument that saved the station at the end of the last Cold War may produce its demise at the start of a new one.
WASHINGTON — NASA has hailed an agreement with the Space Force to share information on near Earth object impacts as a key step forward in planetary defense, even as the agency defers work on a mission it says is critical to tracking such objects.
Mercury can be hard to spot, but late April 2022 is a great time as its the lone visible planet in the evening sky.
HELSINKI — A classified Chinese satellite has been tracked operating in a specialized orbit, six months after an anomaly during launch appeared to leave it stranded in an initial transfer orbit.
Israel punches above its weight in space science and exploration, as it does in most other arenas.
A tug-of-war between neighboring stars led to the formation of two strange types of red giant star, as seen in the eyes of a lost telescope.
As NASA pushes forward to get humans back on the moon, questions have emerged on what this means for the Space Force and what role it might play in lunar activities.

The Hubble Space Telescope caught a galaxy on camera that underlies a much larger structure, known as the Virgo Cluster.
Astronomers in the future may not be able to build large complex power-hungry observatories if they want to reduce their carbon footprint in line with greenhouse gas emission requirements, a study suggests.
When the dinosaur-destroying asteroid collided with Earth 66 million years ago, massive amounts of sulfur — volumes more than were previously thought — were thrown high above land into the stratosphere, a new study finds.
