An article published in the journal “Nature Communications” reports the discovery of uracil, one of the bases of RNA, and niacin, i.e. vitamin B3, in the samples of asteroid Ryugu brought back to Earth by the Japanese Hayabusa 2 space probe. A team of researchers led by Yasuhiro Oba of Japan’s Hokkaido University developed an analytical technique to identify compounds in concentrations between parts per billion and parts per trillion to analyze just over 5 grams of samples.
A few hours ago, SpaceX’s Crew Dragon Endurance spacecraft concluded its Crew-5, or SpaceX Crew-5, mission for NASA by landing without problems. On board were astronauts Nicole Mann, Josh Cassada, and Koichi Wakata and cosmonaut Anna Kikina, who had reached the International Space Station on October 6, 2022, and were part of Expedition 68. The four of them finished the fifth regular crewed mission of SpaceX in the Atlantic Ocean, off the coast of Tampa, Florida. The Crew Dragon departed the Station about nineteen hours earlier.
A few hours ago, SpaceX’s Crew Dragon Endurance spacecraft docked with the Harmony module of the International Space Station completing the first part of its Crew-5 or SpaceX Crew-5 mission that began with its launch about 29 hours earlier. After checking that the pressure was properly balanced, the hatch was opened to allow Koichi Wakata, Nicole Mann, Josh Cassada, and Anna Kikina to enter the Station.
A little while ago, SpaceX’s Crew Dragon Endurance spacecraft blasted off atop a Falcon 9 rocket from the Kennedy Space Center in its Crew-5 or SpaceX Crew-5 mission. After almost exactly twelve minutes, it successfully separated from the rocket’s last stage and went en route to carry out its mission. This is the 5th crewed mission of the Crew Dragon spacecraft within the normal rotation of the International Space Station crew. This is also the second mission for the Endurance.
A few hours ago, SpaceX’s Crew Dragon Endeavour spacecraft ended its Crew-2, or SpaceX Crew-2, mission on behalf of NASA by splashing down without problems. Onboard were astronauts Thomas Pesquet, Megan McArthur, Shane Kimbrough, and Akihiko Hoshide, who reached the International Space Station on April 24, were part of the Expeditions 65 and 66. They finished SpaceX’s second regular crewed mission in the Atlantic Ocean off the coast of Pensacola, Florida. The Crew Dragon left the International Space Station about 8.5 hours 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.
