A few hours ago, SpaceX’s Dragon spacecraft ended its CRS-30 (Cargo Resupply Service 30) mission for NASA splashing down smoothly off the Florida Coast. The Dragon left the International Space Station a little more than 36 hours earlier. For SpaceX, this was the 10th mission of the 2nd contract with NASA to transport supplies to the Station with the new version of the Dragon cargo spacecraft.

Shortly after the splashdown, SpaceX’s recovery ship went to retrieve the Dragon to transport it to the coast. The cargo brought back to Earth will be delivered to NASA within a few hours. The Dragon spacecraft reached the International Space Station on March 23, 2024.

A confirmation has arrived that three Chinese taikonauts from the Shenzhou 18 mission reached the Chinese space station Tiangong with an automated docking maneuver. They blasted off about 6.5 hours earlier atop a Long March-2F rocket from the Jiuquan Satellite Launch Center. They form the 7th crew of the Chinese space station and will remain there for about six months, the standard duration for a mission.

The three taikonauts, as the Chinese call their astronauts, of the Shenzhou 18 mission are Ye Guangfu, Li Cong, and Li Guangsu.

An article published in the journal “Nature” reports the observation of very strong winds coming from the supermassive black hole at the center of the galaxy Cosmos-11142 which inhibited star formation within it. A team of researchers led by Professor Sirio Belli of the University of Bologna, Italy, used the James Webb Space Telescope to detect the movement of cold neutral gas pushed at such a speed that it swept away the gas in the galaxy and thus prevented the formation of new stars. This is the first evidence of how a supermassive black hole can have that effect on a galaxy.

At the European Geophysical Union General Assembly held in Vienna last week, NASA’s Juno mission principal investigator Scott Bolton illustrated some new discoveries offered by the Juno space probe, including some regarding Io, Jupiter’s volcano-covered moon. Io was also studied by a team of researchers who used the ALMA radio telescope to map the movements of sulfur isotopes and reconstruct the tidal heating that generates the intense volcanic activity. The results were published in an article in the journal “Journal of Geophysical Research: Planets”.

An article published in the journal “Nature Astronomy” offers an explanation for the formation of the large and deep basin known as Sputnik Planitia on Pluto with its characteristic heart shape. A team of scientists coordinated by the Swiss University of Bern created computer simulations that indicate that the depression that is some kilometers deep could have been generated by an impact with an object with a diameter of around 700 kilometers that occurred at an oblique angle and was relatively slow. The results of these simulations also suggest that Pluto likely doesn’t have a subsurface ocean of liquid water, unlike other studies.
