Ex-Astronauten kritisieren Nasa für Hitzeschild der Orion-Kapsel bei Artemis-2
Mit der Artemis-2-Mission könnten erstmals seit über 50 Jahren Menschen den Mond umrunden. Einige Experten äußern allerdings Zweifel am Hitzeschild der Kapsel.

A NASA mission that studied the interior of hurricanes collected its final data on Nov. 12, as the last two CubeSats in its fleet were powered down prior to re-entering Earth’s atmosphere: #TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission originally consisted of four identical, milk carton-sized satellites that launched in May 2023.

Nearly 300 years after Immanuel Kant proposed that our solar system’s family of planets condensed from a flattened disk of gas and dust,
NASA’s Hubble Space Telescope revealed that such planetary nurseries are common across our galaxy.
Now, Hubble has identified the largest known protoplanetary disk
—spanning an astonishing 400 billion miles,
roughly 40 times the diameter of our solar system

In 2014, NASA awarded a Commercial Crew Transportation Capability contract to Boeing to fly astronauts to and from the International Space Station with its #Starliner spacecraft; as part of its contract, Boeing was awarded up to six crewed flights to the orbital complex - after a thorough evaluation, the definitive order has been adjusted to four missions, with the remaining two available as options: https://www.nasa.gov/blogs/spacestation/2025/11/24/nasa-boeing-modify-commercial-crew-contract/. The next Starliner flight, known as Starliner-1, will be used by NASA to deliver necessary cargo to the orbital laboratory and allow in-flight validation of the system upgrades implemented following the Crew Flight Test mission last year - NASA and Boeing are targeting no earlier than April 2026 to fly the uncrewed Starliner-1 pending completion of rigorous test, certification, and mission readiness activities.

Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, -- since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper Belt and Oort Cloud.
Now, looking outside our solar system, NASA’s James Webb Space Telescope has returned the first conclusive evidence that links how those conditions are possible.
The telescope clearly showed for the first ti…

In a few minutes NASA will host a live news conference at 22:00 UTC from the agency’s headquarters in Washington to discuss the International Space Station and its crew: #ISS crew member.

None of the NASA s/c images of #3IATLAS shared at the presser come even remotely close in beauty - and obvious detail - to the current best ground-based images ... like this one by Michael Jäger and Gerald Rhemann with a 12-inch reflector taken this morning: https://www.facebook.com/photo/?fbid=2282405328942953

Simultaneously NASA and ESA have published new spacecraft images of #3IATLAS, https://science.nasa.gov/blogs/3iatlas/2025/12/04/nasas-hubble-space-telescope-revisits-interstellar-comet/ from the Hubble Space Telescope on 30 November (just the inner coma with a central condensation) and https://www.esa.int/ESA_Multimedia/Images/2025/12/Comet_3I_ATLAS_shows_activity_in_Juice_navigation_camera_teaser from Juice's NavCam on 2 November with an early sighting of the plasma tail - more contributions to understanding the behavior of the interstellar visitor.
