As I understand it, only one Falcon-9 landing attempt failed because of sto= rmy conditions, and that attempt was in fact cancelled (it was deliberately "la= nded" on the sea instead of on the drone ship). The other failures had other reas= ons, 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, af= ter such persistence, but I think it is a very important step that will force a= ll launcher suppliers to aim towards reusable launchers, leading to huge launch-cost reductions.)" The European Space Agency uses SpaceX. ESA spent circa the same amount of money on a SINGLE INSTRUMENT as Sweden= =20 spent on an ENTIRE SATELLITE with a similar instrument made by Omnisys. ESA uses Serco. Politician Andy Slaughter said during a live interview on= =20 Channel-4 News two nights ago that Serco chose to pay a 68-million-pound=20 fine to avoid criminal prosecution over underperformance. Cf. "Press=20 release Taxpayer compensated for overcharging as cross-government contracts review= =20 concludes Serco will repay =C2=A368.5 million for charging errors as government welco= mes=20 progress on a corporate renewal plan.

So sans=20 its georeturn policy, ESA manages to mismanage anyway. --708268602-1084427857-1749641726=:2843152--
