Today, an Orbital Sciences Corporation Taurus rocket failed.
This is the second Taurus failure in a row and the third of the last four. The cause of this failure is the same as the last - the fairing did not separate properly. The fairing is the shell which goes around the payload of the launch vehicle and provides protection from the elements prior to launch and from the wind during flight.
This is rocket science 101 stuff, and OSC has been working since the last failure to fix it. Being able to separate the two halves of the fairing upon command is absolutely basic as rockets go. OSC uses compressed nitrogen to drive pistons to force the fairing apart; theoretically all that is required is to have valves open and allow the N2 to flow. The pressure readings showed that the N2 did flow, yet the fairing did not separate.
Both payloads lost were NASA climate observing payloads. Today's loss was the Glory mission. With Congress set to cut climate satellite funding, ostensibly to fund human space flight but also because Republicans hate climate science, these are serious losses.
This also calls into question the whole idea of "commercial space". This stuff isn't necessarily hard, but missing one detail can kill you. The laborious paperwork and processes that the old-school NASA + [ JSC John Hopkins etc. ] + [ Lockheed Boeing Ball etc. ] teams put together may in fact be cheaper than "commercial" - if you count the cost of failures.
