ESA to study Falcon 9 breakup over Poland. The European Space Agency has published a call to tender for a study examining the reentry and breakup of a SpaceX Falcon 9 upper stage in February last year, European Spaceflight reports. In the early hours of February 19, 2025, a Falcon 9 second stage underwent an uncontrolled atmospheric re-entry over Poland. At least four fragments of the stage survived re-entry and landed in various locations across the country. While no one was injured and no property was damaged, at least one fragment landed in a populated area.
Not just an academic study … ESA hopes to use data collected during the reentry of the Falcon 9 upper stage over Poland to help predict the risks associated with the re-entry of elongated upper stages. There are currently considerable uncertainties surrounding the physics and dynamics of destructive reentry in the very low-Earth orbit regime, below 150km. It’s not an academic study, as in 2015 there were approximately 80 orbital rocket launches. A decade on, that figure has almost quadrupled, with 317 successful orbital rocket launches occurring in 2025. (submitted by EllPeaTea)
SpaceX targets mid-March for next Starship launch. The company plans to launch Starship’s next test flight in six weeks, SpaceX founder Elon Musk said Sunday, January 25, Space.com reports. The flight will be the 12th overall for Starship but the first of the bigger, more powerful, and much-anticipated “Version 3” (V3) iteration of the vehicle.
A better engine … Starship V3 is slightly taller than V2—408.1 feet (124.4 meters) vs. 403.9 feet (123.1 m), but considerably more powerful. V3 can loft more than 100 tons of payload to low-Earth orbit, compared to about 35 tons for V2, according to Musk. The increased brawn comes courtesy of Raptor 3, a new variant of the engine that will fly for the first time on the upcoming test mission. SpaceX is hoping it proves more reliable than V2 as well.
Seeking information about Challenger artifacts. Back in 2010, Robert Pearlman of CollectSpace bought a batch of 18 space shuttle-era “Remove Before Flight” tags on eBay. It was only later that he pieced together that these tags were, in fact, removed from the external tank of STS 51-L, the ill-fated flight of space shuttle Challenger in 1986. He wrote about the experience on Ars.
How did they get to eBay? … “When the tags were first identified, contacts at NASA and Lockheed, among others, were unable to explain how they ended up on eBay and, ultimately, with me,” Pearlman said. He wants to gather more information about the provenance of the tags so that he can donate them to museums, with their full backstory.
