Mercury released into the oceans affects marine environments worldwide. Traditionally, its distribution and quantity have been estimated using marine biogeochemical simulation models.

The Artemis II astronauts conducted a historic lunar flyby, gathered invaluable data and took in unprecedented moon views, but one of the most crucial moments of their 10-day mission is still to come: Friday’s splashdown.
While the Artemis II astronauts have been protected from the icy vacuum of space on their journey, their bodies have nonetheless been left exposed to possibly high levels of radiation—a danger of space travel that NASA is anxiously waiting to study.
Apart from pesky issues with the spacecraft’s toilet and waste disposal system, most of the Artemis II mission has proceeded like clockwork. NASA has made few changes to the flight plan since the launch of the lunar flyby mission April 1. But ground controllers revamped the timeline Wednesday as the Artemis II astronauts zoomed toward Earth after a close encounter with the Moon earlier this week. The four astronauts were supposed to take manual control Continue ReadingOrion helium leak no threat to Artemis II reentry, but will require redesign
On August 19, 2022, astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very strong spectral fingerprints of calcium II H and hydrogen-epsilon lines. It was the first time these two light signatures were seen in great detail during a flare. According to computer models, those lines were stronger than expected and play a not well-understood role in how flares heat the solar atmosphere where they occur.
Drawing ever closer to Earth, the Artemis II astronauts tidied up their lunar cruiser for its upcoming “fireball” return and reflected on their historic journey around the moon, describing it as surreal and profound.
On April 10, Artemis II—humanity’s first mission to the moon in more than half a century—will draw to a close when the Orion capsule carrying four crew members detaches from its service module.

In the 1970s, the late Jane Goodall observed a community of chimpanzees in Gombe, Tanzania, breaking into two factions; the males in one group ended up killing all the males in the rival group over the next four years, along with one female chimp. But the case was considered an anomaly, although there is genetic evidence suggesting this kind of split is a rare event occurring every 500 years or so. Now researchers have observed Continue ReadingUgandan chimps split into two factions, then killed rivals
The first flyby images of the Moon captured by NASA’s Artemis II astronauts during their historic test flight reveal some regions no human has seen, including a rare in-space solar eclipse. Released Tuesday, astronauts captured the images April 6 during the mission’s seven-hour flyby of the lunar far side, showing humanity’s return to the Moon’s […]

SAN FRANCISCO – Albedo, the former Earth-observation startup now focused on satellite manufacturing, announced plans April 9 to send its second spacecraft into very low-Earth orbit (VLEO). Vicinity, scheduled to launch in 2027, will deploy solar arrays to provide far more power than the solar panels mounted on Precision, the bus that housed Albedo’s 2025 […] The post Albedo prepares second VLEO mission for 2027 launch appeared first on SpaceNews.
