RpK’s missed milestone

The online edition of Space News reported late Wednesday that Rocketplane Kistler missed its May milestone in NASA’s COTS program (subscription required). That milestone required RpK to have completed a second round of private financing by the end of the month; it has yet to complete that round, according to a NASA spokesperson contacted by Space News. NASA doesn’t plan to penalize the company for the missed milestone at the present time, instead choosing to work with the company “on a plan that would provide the company additional time to meet its goal while also meeting NASA’s needs.” RpK, by all accounts, has been making steady technical progress on the K-1 vehicle, announcing back in February that it achieved a systems requirement review for the vehicle three weeks ahead of schedule.
