- ESA is evaluating adapting the Ariane 6 launch vehicle for human spaceflight, studying necessary modifications and certification for crewed missions. - Assessment focuses on safety upgrades, human-rating requirements, and design changes to support astronauts and crewed spacecraft. - The initiative aims to provide Europe with an independent crew access capability to

Why Orbital Data Centers Are Harder Than Silicon Valley Thinks

Why Orbital Data Centers Are Harder Than Silicon Valley Thinks

- Orbital data centers promise lower latency and global coverage but face major engineering challenges. - Heat rejection in vacuum, radiation shielding, and reliability without physical maintenance are significant hurdles. - High launch and deployment costs, limited power availability, and strict mass constraints complicate designs. - Economic and regulatory uncertainties, plus competition from improving

Every Starlink, orbiting now

- Reddit post titled “Every Starlink, orbiting now” shares a visual/map of all Starlink satellites currently in orbit, submitted by u/Mastbubbles. - Post includes a link to an external interactive sheet (https://sheets.works/starlink) and an image preview showing satellite positions. - Linked Reddit discussion and image provide resources for

A giant star may have destroyed itself in one of the universe's rarest explosions

A giant star may have destroyed itself in one of the universe's rarest explosions

- Astronomers report a candidate for a very rare explosion in which an extremely massive star self-destructed rather than collapsed into a black hole. - Observations show unusually bright, long-lasting emission and spectral features consistent with a pair-instability or pulsational pair-instability supernova. - The event challenges models of the

FCC lifts looming deadline for Amazon Leo satellite broadband constellation | The waiver “serves the public interest by promoting a second large satellite broadband constellation.”

FCC lifts looming deadline for Amazon Leo satellite broadband constellation | The waiver “serves the public interest by promoting a second large satellite broadband constellation.”

- The FCC granted a waiver that removes an imminent deadline for Amazon’s Kuiper LEO satellite broadband constellation. - The waiver delays a regulatory milestone Amazon would have otherwise missed, allowing more time to meet deployment requirements. - The FCC said the decision “serves the public interest by promoting a second large
