Zitat von 29. Okt. 2024For those who follow NASA's human spaceflight program, when the Orion spacecraft's heat shield cracked and chipped away during atmospheric reentry on the unpiloted Artemis I test flight in late 2022, what caused it became a burning question.
Multiple NASA officials said Monday they now know the answer, but they're not telling. Instead, agency officials want to wait until more reviews are done to determine what this means for Artemis II, the Orion spacecraft's first crew mission around the Moon, officially scheduled for launch in September 2025.
"We have gotten to a root cause," said Lakiesha Hawkins, assistant deputy associate administrator for NASA's Moon to Mars program office, in response to a question from Ars on Monday at the Wernher von Braun Space Exploration Symposium.
"We are having conversations within the agency to make sure that we have a good understanding of not only what's going on with the heat shield, but also next steps and how that actually applies to the course that we take for Artemis II," she said. "And we'll be in a position to be able to share where we are with that hopefully before the end of the year.”
Zitat von Nov 19, 2024 RELEASE24-143 - NASA HeadquartersNASA Plans to Assign Missions for Two Future Artemis Cargo Landers
NASA expects to assign demonstration missions to current human landing system providers, SpaceX and Blue Origin, to mature designs of their large cargo landers following successful design certification reviews. The assignment of these missions builds on the 2023 request by NASA for the two companies to develop cargo versions of their crewed human landing systems, now in development for Artemis III, Artemis IV, and Artemis V.
“NASA is planning for both crewed missions and future services missions to the Moon beyond Artemis V,” said Stephen D. Creech, assistant deputy associate administrator for technical, Moon to Mars Program Office. “The Artemis campaign is a collaborative effort with international and industry partners. Having two lunar lander providers with different approaches for crew and cargo landing capability provides mission flexibility while ensuring a regular cadence of Moon landings for continued discovery and scientific opportunity.”
NASA plans for at least two delivery missions with large cargo. The agency intends for SpaceX’s Starship cargo lander to deliver a pressurized rover, currently in development by JAXA (Japan Aerospace Exploration Agency), to the lunar surface no earlier than fiscal year 2032 in support of Artemis VII and later missions. The agency expects Blue Origin to deliver a lunar surface habitat no earlier than fiscal year 2033.
“Based on current design and development progress for both crew and cargo landers and the Artemis mission schedules for the crew lander versions, NASA assigned a pressurized rover mission for SpaceX and a lunar habitat delivery for Blue Origin,” said Lisa Watson-Morgan, program manager, Human Landing System, at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These large cargo lander demonstration missions aim to optimize our NASA and industry technical expertise, resources, and funding as we prepare for the future of deep space exploration.”
SpaceX will continue cargo lander development and prepare for the Starship cargo mission under Option B of the NextSTEP Appendix H contract. Blue Origin will conduct its cargo lander work and demonstration mission under NextSTEP Appendix P. NASA expects to issue an initial request for proposals to both companies in early 2025.
Apropos Blue Origin: vor 4 Minuten Landung der New Shepard-Kapsel des suborbitalen Flugs NS-28 in Texas, 9. bemannter Flug, RSS First Step, 7. suborbitaler Flug in diesem Jahr. (Technisch gesehen zählen auch die bisherigen Starship-Flüge zu dieser Kategorie, da dort keine Umlaufbahngeschwindigkeit erreicht wurde & der Wiedereintritt in die Atmosphäre somit ohne Bremszündung erfolgt ist, aber ich zähle sie hier nicht mit, da diese Testflüge ein ganz leicht anderes Einsatzprofil haben als ein kurzer Hüpfer über die Kármán-Linie.)

Zitat China launched its first Long March 12 rocket Saturday, marking an advance in its crewed moon plans and the debut of a new spaceport that will boost the country’s access to space.
The two-stage, 62-meter-tall Long March 12 lifted off at 9:25 a.m. Eastern (1425 UTC) Nov. 30 from the Wenchang Commercial Space Launch Site. The rocket climbed into the night sky above the coastal spaceport, with amateur live streams from the area capturing the event.
The kerosene-fueled Long March 12 is China’s first 3.8-meter-diameter launch vehicle. It can carry a payload of 12,000 kilograms to low Earth orbit (LEO), and 6,000 kg to sun-synchronous orbit (SSO), according to SAST. The new rocket could play a role in the construction of China’s planned LEO megaconstellations.
The launch is a step forward for SAST in bringing new rockets online, for its parent company CASC in the development of new rocket engines for its lunar plans and, through the debut launch from the new commercial Wenchang spaceport, the easing of a bottleneck in access to launch pads in China. It is distinct from Wenchang’s existing national spaceport and is made to enable higher launch frequencies for multiple CASC and commercial rockets.
China had aimed to launch around 70 Long March rockets in 2024 and approximately another 30 launches from commercial providers. A lack of reusable launchers and options for launch pads likely contributed to the slower than expected pace, with the launch being China’s 59th orbital launch attempt with just a month of 2024 remaining.
The launch was the first flight use of the YF-100K engine, with the Long March 12 using four YF-100K engines on its first stage. The YF-100K is an uprated version of the YF-100 kerosene-liquid oxygen engines that power China’s new-generation liquid propellant rockets. These newer rockets include the Long March 5, 6, 7 and 8.
The YF-100K notably will power the first stages of the Long March 10 rocket. That launcher is intended to send China’s astronauts to the moon before the end of the decade. A reusable version of the engine, the YF-100N, is also being developed.
