A few hours ago the Soyuz MS-17 spacecraft was launched from the Baikonur Cosmodrome in Kazakhstan and after a little more than three hours reached the International Space Station with three astronauts on board: Kate Rubins, Sergey Ryzhikov and Sergey Kud-Sverchkov. For the first time, the ultra-fast route was used which halves the journey duration. In the period preceding a launch, it’s normal for astronauts and cosmonauts to remain in quarantine. In this case it was also extended to the personnel who managed the launch, with limits to the people who could have been in Baikonur.

A few hours ago Northrop Grumman’s Cygnus spacecraft blasted off atop an Antares rocket from the Mid-Atlantic Regional Spaceport (MARS), part of NASA’s Wallops Flight Facility (WFF) on Wallops Island. After about nine minutes it successfully separated from the rocket’s last stage went en route to its destination. This is its 14th official mission, called NG-14 or CRS NG-14, to transport supplies to the International Space Station for NASA.

Three articles, one published in the journal “Nature” and two published in the journal “Geophysical Research: Planets”, report various aspects of research on the clouds of the planet Jupiter. Three teams of researchers with various members in common, coordinated by the French CNRS’s Laboratoire Lagrange and NASA’s JPL, used data collected by the Juno space probe to analyze various aspects of the role of water in the violent storms in the Jovian atmosphere. Lightning strikes originate in a solution of water and ammonia, substances that can form a sort of hailstones, nicknamed mushballs by the researchers, which play a key role in the atmospheric dynamics of this gas planet.

A little while ago SpaceX’s Crew Dragon Endeavor spacecraft ended its SpX-DM2 (SpaceX Demonstration Mission 2) or SpaceX Demo-2 mission on behalf of NASA by landing without problems. On board were American astronauts Bob Behnken and Doug Hurley, who finished SpaceX’s first crewed mission in the Atlantic Ocean off Pensacola, Florida. The Crew Dragon left the International Space Station almost a day earlier. Shortly after splashing down, the SpaceX ship called “Go Navigator” went to retrieve the Crew Dragon and its crew to transport them to the coast.
