The area around the Acheron Fossae region on Mars

0

ESA has released images of the Acheron Fossae region on Mars captured by its Mars Express space probe’s High Resolution Stereo Camera (HRSC). The peculiarity of these images is that they show the two faces of Mars, meaning that they show how the red planet is basically divided into two parts with very different geological characteristics. About half of Mars is composed of an ancient terrain marked by craters and other signs of age and activity, while the other half is much smoother, with a surface probably reshaped by lava from volcanoes that are no longer active.

A few hours ago, the Soyuz MS-27 spacecraft was launched from the Baikonur Cosmodrome in Kazakhstan and, after a little more than three hours, reached the International Space Station with three new crew members on board. It docked with the Station’s Prichal module. The ultra-fast track was used, which halves the journey duration and is used whenever the Station’s position makes it possible.

A few hours ago, SpaceX’s Crew Dragon Resilience spacecraft completed its Fram2 mission with a safe splashdown. Chun Wang, Rabea Rogge, Jannicke Mikkelsen, and Eric Philip were on board and completed this completely private space mission in the Pacific Ocean after spending just over three and a half days in orbit. Shortly after splashdown, SpaceX’s “MV Shannon” ship picked up the Resilience and its crew and transported them to the coast.

A few hours ago, the SpaceX Crew Dragon Resilience spacecraft blasted off atop a Falcon 9 rocket from the Kennedy Space Center on the Fram2 mission. After about twelve minutes, it successfully separated from the rocket’s last stage. It will spend between 3 and 5 days in orbit. Unlike the previous private space missions conducted by SpaceX in recent years, in the Fram2, the Crew Dragon entered a polar orbit, the first time for a crewed space flight, at an altitude that will range between 425 and 450 kilometers.

An article published in the journal “Nature” reports the results of observations of the primordial galaxy cataloged as JADES-GS-z13-1. A team of researchers used the James Webb Space Telescope to examine this galaxy, estimating that it dates back to about 330 million years after the Big Bang. The surprise came from spectroscopic analyses with so-called Lyman-alpha radiation, emitted in the ultraviolet by hydrogen in specific circumstances, because it was much stronger than would be expected from a galaxy of that era.
