Nasa Announces Artemis III Mission No Longer Aims To Send Humans To Moon

Nasa announced on Friday radical changes to its delayed Artemis III mission to land humans back on the moon, as the US space agency grapples with technical glitches and criticism that it is trying to do too much too soon. From a report: The abrupt shift in strategy was laid out by the space agency's recently confirmed administrator, Jared Isaacman. Announcing the changes on Friday, he said that Nasa would introduce at least one new moon flight before attempting to put humans back on the lunar surface for the first time in more than half a century, in 2028. The new, more incremental approach would give the Nasa team a chance to test flight and refine its technology. As part of the changes, the Artemis II mission to fly humans around the moon this year, without landing, would also be pushed back from its latest scheduled launch on 6 March to 1 April at the earliest. "Everybody agrees this is the only way forward," Isaacman told reporters at a news conference. "I know this is how Nasa changed the world, and this is how Nasa is going to do it again."

NASA Reveals Identity of Astronaut Who Suffered Medical Incident Aboard ISS

Longtime Slashdot reader ArchieBunker shares a report from NBC News: NASA revealed that astronaut Mike Fincke was the crew member who suffered a medical incident at the International Space Station in January, which prompted the agency to carry out the first evacuation due to a medical issue in the space station's 25-year history. The rare decision to cut a mission short and bring Fincke and three other crew members home early made for a dramatic week in space early this year. In a statement released by NASA "at the request of Fincke," the veteran astronaut said he experienced a medical event on Jan. 7 "that required immediate attention" from his space station crew members. "Thanks to their quick response and the guidance of our NASA flight surgeons, my status quickly stabilized," Fincke, 58, said in the statement. [...] In his statement, Fincke thanked his Crew-11 colleagues, along with NASA astronaut Chris Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, who were also aboard the space station at the time and are still in space. Fincke also thanked the teams at NASA, SpaceX and the medical professionals at Scripps Memorial Hospital La Jolla. "Their professionalism and dedication ensured a positive outcome," he said. Fincke ended his statement by saying he is "doing very well" and still actively involved with standard post-flight reconditioning at NASA's Johnson Space Center in Houston. "Spaceflight is an incredible privilege, and sometimes it reminds us just how human we are," he said. "Thank you for all your support."

Rapport Starliner : la Nasa classe l’incident au niveau des catastrophes Challenger et Columbia

Dans une conférence de presse annoncée au dernier moment, la Nasa a fait le point sur les déboires de Starliner, plus d'un an et demi après. Des ratés avaient perturbé lourdement la mission, forçant même les astronautes à rester bien plus longtemps que prévu à bord de l'ISS. L'analyse finale de l'agence spatiale américaine est très dure à l'égard de Boeing, le fabricant de la capsule, mais aussi envers elle-même.

NASA Chief Classifies Starliner Flight As 'Type A' Mishap, Says Agency Made Mistakes

NASA has officially classified Boeing Starliner's 2024 crewed flight as a "Type A" mishap, acknowledging serious technical failures and leadership shortcomings that nearly left astronauts unable to safely return. Administrator Jared Isaacman released (PDF) a 311-page internal report citing flawed decision-making and cultural issues, with the next Starliner flight now planned as uncrewed pending major fixes. Ars Technica reports: As part of the announcement, NASA Administrator Jared Isaacman sent an agency-wide letter that recognized the shortcomings of both Starliner's developer, Boeing, as well as the space agency itself. Starliner flew under the auspices of NASA's Commercial Crew Program, in which the agency procures astronaut transportation services to the International Space Station. "We are taking ownership of our shortcomings," Isaacman said. "Starliner has design and engineering deficiencies that must be corrected, but the most troubling failure revealed by this investigation is not hardware," Isaacman wrote in his letter to the NASA workforce. "It is decision-making and leadership that, if left unchecked, could create a culture incompatible with human spaceflight." Isaacman said there would be "leadership accountability" as a result of the decisions surrounding the Starliner program, but did not say which actions would be taken.

Pourquoi Elon Musk et Emmanuel Macron se disputent sur les réseaux sociaux

Lors d'un discours à Anvers, Emmanuel Macron a encouragé l'Europe à mieux financer ses pépites et à préférer les solutions européennes. Son exemple : Elon Musk, « un gars sursubventionné par les agences fédérales aux États-Unis ». Le milliardaire réfute cette déclaration : selon lui, c'est l'Europe qui sursubventionne les concurrents de ses entreprises.
