A few hours ago, the Progress MS-23 spacecraft blasted off atop a Soyuz 2.1a rocket from the Baikonur Cosmodrome in Kazakhstan. After about nine minutes it successfully separated from the rocket’s last stage and was placed on its ultra-fast track in its resupply mission to the International Space Station also called Progress 84 or 84P. After almost 3.5 hours it reached the International Space Station docking with its Poisk module. The ultra-fast track requires very precise maneuvering and a favorable position of the Station. For this reason, it wasn’t used in the previous two Russian resupply missions.

An article published in the journal “Nature Astronomy” reports a solution to the mystery of the change in color of some belts of the planet Jupiter’s atmosphere. A team of researchers used data collected by NASA’s Juno space probe to link those changes to the planet’s magnetic field. Scientists already knew the connection with variations in the infrared band, which means the propagation of electromagnetic field energy, about 50 kilometers below Jupiter’s surface. This new study brings evidence that the variations may in turn be caused by waves produced by the planetary magnetic field at depth.

A little while ago, SpaceX’s Crew Dragon Freedom spacecraft docked with the International Space Station’s Harmony module performing the first part of its private mission Axiom Mission 2 or simply Ax-2. It blasted off atop a Falcon 9 rocket from the Kennedy Space Center when it was afternoon in the USA. After verifying that the pressure is properly balanced, the hatch will be opened to allow crew members to enter the Station.

A little bit more than one year after the Ax-1 mission, a new collaboration between public entities, which this time besides NASA includes the Saudi Space Commission, and private ones, sent new astronauts to the International Space Station to conduct a series of scientific experiments on behalf of entities that generally can’t carry out studies in microgravity conditions.

The Lupus 3 molecular cloud

An image captured by the Dark Energy Camera (DECam) at the Cerro Tololo Observatory in Chile shows the star-forming interstellar cloud cataloged as Lupus 3. Full of activity, it contains protostars that are literally breaking out of their cocoon of gas and dust such as HR 5999 and HR 6000, in the center of the image. The light of those very young stars illuminates the reflection nebula cataloged as Bernes 149. This area is in the cosmic neighborhood, so it’s observed all the time, sometimes obtaining breathtaking images of newborn stars and protostars.

Images captured by the Mars Rover Perseverance in an area nicknamed Skrinkle Haven in Jezero Crater on Mars indicate the presence of a river that flowed into that crater in ancient times. The surprise is that the layers of sediments and pebbles that form what was called a curvilinear unit suggest that that river was deeper and more powerful than all other ancient Martian rivers identified so far. A hill nicknamed Pinestand about 450 meters from Skrinkle Haven may have been formed by a powerful river but scientists are assessing other explanations as well.
