Continuing work left over from a spacewalk last month, astronauts Nicole Mann and Koichi Wakata headed outside the International Space Station Thursday to finish installing a mounting bracket for new solar arrays due to arrive at the complex on a SpaceX resupply mission in June.
With moon crews to assign, Joe Acaba named NASA's new chief astronaut
As NASA nears selecting its first crew to fly to the moon in more than 50 years, the agency has a new leader for its astronaut corps, Joe Acaba, who has flown into space on three missions.
Artemis 1 moon rocket looks ready for astronaut missions, NASA says
NASA's Space Launch System megarocket aced its first-ever liftoff late last year and appears ready to take the next big step — launching astronauts.
The Historic Discussion of Ptolemy’s Star Catalog
From the time of its writing in the 2nd century CE, Claudius Ptolemy’s Almagest stood at the forefront of mathematical astronomy for nearly 1,500 years. This work included a catalog of 1,025 stars, listing their coordinates (in ecliptic longitude and latitude) and brightnesses. While astronomers within a few centuries realized that the models for the sun, moon, and planets all had issues (which we today recognize as being a result of them being incorrect, geocentric models relying on circles and epicycles instead of a heliocentric model with elliptical orbits), the catalog of stars was generally believed to be correct.
Lucy Mission Has a New Asteroid to Fly By
NASA’s Lucy mission now has a new first target of opportunity, a main-belt asteroid it will visit this November.
New satellite to police carbon dioxide emitters from space
The first-ever satellite designed to detect major emitters of the greenhouse gas carbon dioxide is set to launch to space this year.
The First Stars May Have Weighed More Than 100,000 Suns
The universe was simply different when it was younger. Recently astronomers have discovered that complex physics in the young cosmos may have led to the development of supermassive stars, each one weighing up to 100,000 times the mass of the Sun.
Drag Sail Success! This Satellite Won't Turn Into Space Junk
The European Space Agency successfully tested a solar-sail-type device to speed up the deorbit time for a used cubesat carrier in Earth orbit. The so-called breaking sail, the Drag Augmentation Deorbiting System (ADEO) was deployed from an ION satellite carrier in late December 2022. Engineers estimate the sail will reduce the time it takes for the carrier to reenter Earth’s atmosphere from 4-5 years to approximately 15 months.
Saturn's moon Mimas may be a 'stealth' ocean world
The icy Saturn moon Mimas may have a geologically young internal ocean surrounded by a thinning ice shell, new research suggests.

Good News! Webb is Fully Operational Again
The James Webb Space Telescope is back to full science operations. One of the telescope’s instruments, the Near Infrared Imager and Slitless Spectrograph (NIRISS) had been offline since January 15 due to a communications error. But engineers worked through the problem and were able to return the instrument to full operations.
