A little while ago SpaceX’s Crew Dragon spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its SpX-DM2 (SpaceX Demonstration Mission 2) or SpaceX Demo-2 mission. After about eleven minutes, it successfully separated from the rocket’s last stage and went en route to carry out its mission. This is the first crewed mission of the Crew Dragon spacecraft, in this case with Doug Hurley and Bob Behnken on board.

A graphic of the combined observations of Jupiter

An article published in “The Astrophysical Journal Supplement Series” reports the results of a series of combined observations of the planet Jupiter. A team of researchers led by Michael Wong of the University of California, Berkeley, used data collected by the Hubble Space Telescope, the Gemini Observatory in Hawaii and NASA’s Juno space probe to obtain a broader picture of various phenomena taking place in Jupiter’s atmosphere. Storms include the Great Red Spot, which the combined observations help us understand better.

Europa seen by the Galileo space probe

NASA has published reprocessed versions of three old photos of areas of the surface of Jupiter’s large moon Europa taken by the Galileo space probe on September 26, 1998. NASA scientists applied some processing techniques developed in recent years to the images obtaining new details of a series of geological features existing at the time on Europa’s frozen surface. This result offers is immediately useful for scientists interested in studying this moon and for the future because NASA is preparing the Europa Clipper mission, which also aims to try to understand what’s hidden in Europa’s underground ocean, with the hope to find life forms.

The Moon landers by Dynetics, SpaceX and Blue Origin / National Team

NASA has announced the choice of three companies to design and develop human landing systems for the Artemis program. These are essentially plans for a lunar lander among which one will be selected to be built for the mission that, according to plans, is supposed to bring American astronauts back to the Moon by 2024. The companies selected are Blue Origin (actually the first contractor for a group called National Team), Dynetics, and SpaceX. This stage of development involves a 10-month base period during which companies and NASA will work together on the selected projects. The total contract value is $967 million.

An article published in “The Astrophysical Journal Letters” reports the discovery of the exoplanet Kepler-1649c, which has a size very similar to the Earth’s and orbits in ​​its system’s habitable zone. A team of researchers led by Andrew Vanderburg of the University of Texas, Austin, reanalyzed data collected by NASA’s Kepler space telescope and subsequently analyzed using software written for that task. Initially, only one exoplanet was confirmed in that system while another candidate was discarded. A human verification led to the confirmation of the planet that was cataloged as Kepler-1649c. The two planets’ orbital characteristics suggest the possibility that a third one exists, even if for now the researchers haven’t been able to find any traces of it.
