tater Posted June 12, 2022 Author Share Posted June 12, 2022 Holding at T-15 min Turned sound back on, sounds like go/no-go polling before I turned sound off they said something about trying to "resolve this hold" so it's not just go/no-go. Wayward boats is the hold. Quote Link to comment Share on other sites More sharing options...

Scotius Posted June 12, 2022 Share Posted June 12, 2022 (edited) Uh-oh indeed. Apparently upper stage failed just short of achieving orbital speed. RIP payload . Edited June 12, 2022 by Scotius Quote Link to comment Share on other sites More sharing options...

tater Posted August 5, 2022 Author Share Posted August 5, 2022 "WASHINGTON — Astra Space announced Aug. 4 it is canceling its existing small launch vehicle after its most recent failure and will focus instead on a much larger vehicle that may not be ready to fly customers until 2024." "The company, which reported a net loss of $82.3 million and negative adjusted earnings before interest, taxes, depreciation and amortization of $48.4 million in the second quarter, has $200.7 million in cash and cash equivalents on hand. The company announced Aug. 2 an agreement with B. Riley Principal Capital II to sell up to $100 million in stock over the next two years." Never really been an Astra fan, tbh. The smallsat launch market is a dead end. Not flying anything for real until 2024? Bad time to enter the market assuming that by then we have Starship at some level, plus Vulcan, plus NG, and possibly the new Rocket Lab vehicle (ignoring outfits like Relativity and Firefly).

Not to mention, that customer is NASA of all things. Who paid to launch those satellites in 2022, not 2024 (and the first of which failed to reach orbit).

tater Posted August 5, 2022 Author Share Posted August 5, 2022 Mobile launch for smallsats is a good idea, it gives inclination flexibility, the question is who needs smallsats in bespoke orbits at this point? Quote Link to comment Share on other sites More sharing options...

RCgothic Posted September 28, 2022 Share Posted September 28, 2022 Excessive fuel consumption by upper stage engine apparently. Currently not stated why, but they've been able to recreate this in ground testing. Quote Link to comment Share on other sites More sharing options...

sevenperforce Posted March 3, 2023 Share Posted March 3, 2023 Interesting article from Gizmodo on the failure of the Astra launch last year. https://gizmodo.com/astra-investigation-uncovers-cause-failed-rocket-launch-1850179612 The Aether engine that Astra uses for its upper stage is a pressure-fed kerolox engine similar to the SpaceX Kestrel, but it evidently uses the kerosene for regenerative cooling. The Kestrel used helium pressurant for regenerative cooling. The investigation revealed that the temperature at the pad was greater than usual and so the temperature of the kerosene in the upper stage was elevated, leading to a phase change in the injector which reduced the flow of kerosene through the nozzle and caused a burn-through. Rockets are hard. Quote Link to comment Share on other sites More sharing options...
AckSed Posted March 3, 2023 Share Posted March 3, 2023 Huh. Given the dire warnings of cooling phenomena I've heard floating about - polymerisation, coking and sulphur - how common is using kerosene to cool? I wonder if they have to be careful about where they source their RP-1? Quote Link to comment Share on other sites More sharing options...
