A few hours ago, the Progress MS-20 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 81 or 81P. After almost 3.5 hours it reached the International Space Station docking with its Zvezda module.

An article accepted for publication in the journal “Publications of the Astronomical Society of Japan” reports the discovery of the exoplanet Ross 508 b, probably a super-Earth at the edge of ​​its star system’s habitable zone. A team of researchers led by Hiroki Harakawa used the IRD (InfraRed Doppler) instrument mounted on the Subaru Telescope to examine the star Ross 508, a red dwarf that has a mass that is only 18% of the Sun’s. The radial velocity method allowed to identify what from the collected data looks like a rocky planet with a mass that is about 4 times the Earth’s. This discovery confirms the value of infrared spectroscopic examinations of red dwarfs.

A few hours ago, Boeing’s CST-100 Starliner spacecraft landed at the White Sands Missile Range in New Mexico, ending its Boe-OFT 2 (Boeing Orbital Flight Test 2) mission. It departed the International Space Station, where it arrived on May 21, just over 4 hours earlier. The Starliner doesn’t splash down in the ocean but lands on the ground. The ground staff intervened in an assistance activity exercise that will take place in missions with astronauts. On board were over 250 kg of miscellaneous cargoes that need to be unloaded and the Rosie dummy.

A few hours ago, Boeing’s CST-100 Starliner spacecraft docked with the International Space Station’s Harmony module carrying out the first part of its Boe-OFT 2 (Boeing Orbital Flight Test 2) or OFT-2 mission which began with the launch just over 24 hours earlier. The hatch is scheduled to open in the American morning and all work on the Starliner will be completed rather quickly, as it could depart already on May 25.

A few hours ago, Boeing’s CST-100 Starliner spacecraft blasted off atop a ULA Atlas V rocket from Cape Canaveral on the Boe-OFT 2 (Boeing Orbital Flight Test 2) mission. After about fifteen minutes it successfully separated from the rocket’s last stage and about half an hour after launch it carried out the maneuvers to enter orbit and begin the pursuit of the International Space Station.
