Mosteo @ 2016-04-08 21:09 UTC (permalink / raw) So SpaceX just achieved its first successful landing of the Falcon rocket, and not long ago Blue Origin did something similarly remarkable. Whenever I see these feats of engineering I feel the tingle of my real-time software itch and wonder what they use for these projects. Any idea if there's any Ada in there, or what they use in general? Cheers, Alex. ^ permalink raw reply [flat|nested] 10+ messages in thread

Normal engineering cannot pretend to design everything correctly right from the beginning. So, expect some debugging runs. ;-) ^ permalink raw reply [flat|nested] 10+ messages in thread

So, expect some debugging runs. ;-) Design it landed horizontally, using rocket of course, may increase success rate since it is not vulnerable to winds and waves. ^ permalink raw reply [flat|nested] 10+ messages in thread

As I understand it, only one Falcon-9 landing attempt failed because of stormy conditions, and that attempt was in fact cancelled (it was deliberately "landed" on the sea instead of on the drone ship). The other failures had other reasons, I believe, and I've not seen SW problems mentioned as reasons. (I'm very happy that SpaceX succeeded here. Not only do they deserve it, after such persistence, but I think it is a very important step that will force all launcher suppliers to aim towards reusable launchers, leading to huge launch-cost reductions.) -- Niklas Holsti Tidorum Ltd niklas holsti tidorum fi . @ . ^ permalink raw reply [flat|nested] 10+ messages in thread

The European Space Agency uses SpaceX. ESA spent circa the same amount of money on a SINGLE INSTRUMENT as Sweden spent on an ENTIRE SATELLITE with a similar instrument made by Omnisys. ESA uses Serco. Politician Andy Slaughter said during a live interview on Channel-4 News two nights ago that Serco chose to pay a 68-million-pound fine to avoid criminal prosecution over underperformance. Cf. "Press release Taxpayer compensated for overcharging as cross-government contracts review concludes Serco will repay £68.5 million for charging errors as government welcomes progress on a corporate renewal plan. From: Cabinet Office, Ministry of Justice, Efficiency and Reform Group and Crown Commercial Service Published 19 December 2013 [. . .] The Justice Secretary Chris Grayling has confirmed a settlement with Serco to recompense the taxpayer £68.5 million [. . .] [. . .] [. . .] The company’s conduct under these contracts is now subject to a criminal investigation by the Serious Fraud Office. On 28 August the Justice Secretary announced that Serco’s contract for escorting prisoners to courts (the “PECS” contract) had been referred to the City of London Police. This followed the discovery that members of Serco staff had been recording prisoners as having been delivered ready for court when in fact they were not. [. . .]" Serco demanded ESA employees to sign false confirmations when ESA used to employ me. ESA bribes countries so they refuse to investigate against ESA. So sans its georeturn policy, ESA manages to mismanage anyway. ^ permalink raw reply [flat|nested] 10+ messages in thread

I believe SpaceX won atleast one contract against Blue Origin during an interim senators term who met with him when their application was awarded outstanding despite not meeting the level to qualify at all. The NASA director said he would hold SpaceX to deliver before releasing any further funds during Bidens term but he has been removed.

The NASA director said he would hold SpaceX to deliver before releasing any further funds during Bidens term but he has been removed. Has any re-usability beyond what the space shuttle achieved actually been demonstrated?" This webpage reports one theory about a recent allegation about SpaceX's Starlink: Max Hunder, "Ukraine says Starlink's global outage hit its military communications", July 25, 20258:44 AM GMT+1, HTTPS://WWW.Reuters.com/business/media-telecom/ukraine-says-starlinks-global-outage-hit-its-military-communications-2025-07-25 A few minutes earlier than this webpage I heard a radio station report this theory and a rival theory. I looked at TV to find a (possible) report but I failed to find even a hint of a report shown by TV. I looked at Starlink.com but I failed to find a confession. Corinne Reichert, "Starlink Restored After Hours-Long Outage Took Down Elon Musk's Satellite Internet Service", July 24, 2025 4:55 p.m. PT, HTTPS://WWW.CNet.com/news-live/starlink-restored-after-hours-long-outage-took-down-elon-musks-satellite-internet-service reports that Starlink did confess on X. (X does not allow non-users to read.) That CNet webpage reports this same theory as Reuters without a rival theory. These outages do not happen to rival satellite Internet constellations. That CNet webpage reports that Starlink also uses T-Mobile for "texting". Deutsche Telekom AG owns T-Mobile. T-Systems GEI GmbH (Deutsche Telekom) uses Ada. ^ permalink raw reply [flat|nested] 10+ messages in thread
