Webb reaches alignment milestone
Following the completion of critical mirror alignment steps, the NASA/ESA/CSA James Webb Space Telescope team expects that Webb’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve.

Lunar scientists and engineers design Moon cave explorer
Lunar caves are not only a geologically pristine record of the Moon's history, but they could also provide a safe home for future human explorers. Building upon ESA Discovery's OSIP call and SysNova challenge, ESA gathered a spectrum of over 60 experts in many different areas of science and engineering to design a mission to enter a pit on the Moon's surface and explore the entrance to a lunar cave.

Planet Labs PBC (NYSE: PL) has announced the general availability of the next generation of its PlanetScope Monitoring product, offering high quality, analysis-ready data to all existing PlanetScope customers. While previously offering four spectral bands, PlanetScope will now include eight spectral bands in addition to a series of enhancements, providing customers with richer, cleaner, and more Sky is not the limit for solar geoengineering
There are practical limits to the height at which aerosols may be deployed in the atmosphere to deflect incoming sunlight and countervail global warming. Very high-altitude injections might be more effective, but such climate intervention comes with substantially increased costs and safety risks, according to new research published in Environmental Research Communications.
Following a prom NASA sharpens focus of James Webb Space Telescope
NASA on Wednesday planned to release details about how the agency is sharpening the focus of the large main mirror on the James Webb Space Telescope, which will start peering at the earliest galaxies in the universe soon.
NASA plans to update the press and the public on James Webb progress during a virtual press conference at noon EDT.

Two NASA astronauts completed a spacewalk Tuesday to prepare for the installation of new solar arrays at the International Space Station, amid tension between Russia and the United States over the Ukraine conflict.
Astronauts Kayla Barron, 34, and Raja Chari, 44, spent six hours and 54 minutes on their spacewalk, having exited the station around 8:15 a.m. EDT - their second and first spac Astra launches three satellites in successful mission from Alaska
California-based rocket company Astra Space launched three small satellites from Alaska on Tuesday morning and said the payloads deployed successfully.
The rocket, LV0009, lifted off from Pacific Spaceport Complex on Kodiak Island as planned at 9:22 a.m. PDT.
"We have great news to report," Astra CEO Chris Kemp said on a live broadcast a little over an hour after launch. "The pay NASA system predicts impact of small asteroid
A small asteroid hit Earth's atmosphere over the Norwegian Sea before disintegrating on March 11, 2022. But this event wasn't a complete surprise: Astronomers knew it was on a collision course, predicting exactly where and when the impact would happen.
Two hours before the asteroid made impact, K. Sarneczky at the Piszkéstető Observatory in northern Hungary first reported observations of the small object to the Minor Planet Center—the internationally recognized clearinghouse for the position measurements of small celestial bodies. The object was posted on the Minor Planet Center's Near-Earth Object Confirmation Page to flag it for additional observations that would confirm it as a previously unknown asteroid.
NASA's "Scout" impact hazard assessment system then took these early measurements to calculate the trajectory of 2022 EB5. As soon as Scout determined that 2022 EB5 was going to hit Earth's atmosphere, the system alerted the Center for Near Earth Object Studies (CNEOS) and NASA's Planetary Defense Coordination Office, and flagged the object on the Scout webpage to notify the near-Earth object observing community. Maintained by CNEOS at NASA's Jet Propulsion Laboratory in Southern California, Scout automatically searches the Minor Planet Center's database for possible new short-term impactors.
