SpaceX has just completed the In-Flight Abort Test of one of its Crew Dragon spacecraft, the version of Dragon 2 produced for the transport of astronauts. A Falcon 9 rocket was deliberately blown up at the moment of maximum dynamic pressure, Max q in jargon, to test that the the systems which in a normal launch are used to rescue the crew aboard the Crew Dragon work properly.
An article submitted for publication in “The Astrophysical Journal” reports the initial results of an investigation about the center of the Milky Way conducted using the SOFIA flying telescope to capture infrared details never seen before and therefore useful for mapping an area 600 light years across. A team of researchers integrated those observations with data previously collected using NASA’s Spitzer space telescope and ESA’s Herschel space observatory obtaining a map of the center of the galaxy useful for example to understand where gas is concentrated which can lead to the new stars’ formation, how some of the most massive stars in the Milky Way formed in a relatively small region or where materials are likely to be devoured by the supermassive black hole at the center of the galaxy.
Three articles submitted for publication in “The Astrophysical Journal” report various aspects of a study of the TOI 700 system and the discovery of three exoplanets thanks to the observations made by NASA’s TESS space telescope. Several researchers collaborated to confirm the existence of the three exoplanets and to study their characteristics, in particular TOI 700 d, the outermost and the only one of the three to orbit in the habitable zone of its system. Its existence was also confirmed using the Spitizer space telescope making it the first rocky exoplanet discovered by TESS in the habitable zone.
A little while ago the SpaceX Dragon spacecraft ended its CRS-19 (Cargo Resupply Service 19) mission for NASA splashing down smoothly in the Pacific Ocean almost 500 kilometers (about 300 miles) off the coast of California. The Dragon left the International Space Station a few hours earlier.
Shortly after landing, SpaceX boats went to retrieve the Dragon to transport it to the coast. The cargo brought back to Earth will be delivered to NASA soon, probably tomorrow. The Dragon spacecraft reached the International Space Station on December 8, 2019.
Boeing has announced that its engineers and technicians are conducting an in-depth examination of its CST-100 Starliner spacecraft, which landed on December 22 after the premature end of its Boe-OFT (Boeing Orbital Flight Test) mission. The exam includes the recovery of all the data recorded by the on-board systems to obtain final answers on the problem that caused an off-nominal orbit insertion about half an hour after launch. After landing at the White Sands Missile Range, New Mexico, the name Calypso was proposed by astronaut Sunita Williams and quickly approved, therefore it will be the official name used in the next missions, as the spacecraft is reusable.
