A few hours ago, SpaceX’s Crew Dragon Freedom spacecraft concluded its Ax-2 mission by splashing down without problems. On board were Peggy Whitson, Ali AlQarni, John Shoffner, and Rayyanah Barnawi, who ended this completely private space mission in the Atlantic Ocean after leaving the International Space Station about 12 hours earlier. Shortly after splashing down, SpaceX’s recovery ship went to retrieve the Freedom and its crew to transport them to the coast.

A confirmation has arrived that three Chinese taikonauts from the Shenzhou 16 mission reached the Chinese space station Tiangong with an automated docking maneuver. They blasted off about seven hours earlier on a Long March-2F rocket from the Jiuquan Satellite Launch Center. They form the fifth crew of the Chinese space station and will remain there for about six months, the standard duration for a mission.

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.
