WASHINGTON — Voyager Technologies remains upbeat about the prospects for its Starlab commercial space station but is hoping for some tweaks to NASA’s plans to support the station’s development. Voyager, the majority shareholder in the Starlab Space joint venture responsible for the station, is among the companies awaiting the next phase in NASA’s Commercial Low Earth Orbit Destinations, or CLD, program. Later in the call, Dylan Taylor, chief executive of Voyager, said the company had raised some issues in the draft RFP regarding requirements NASA proposed imposing on commercial stations. “So, I think there are going to be elements of the requirements that, in the final RFP, will be either changed or relaxed a bit.” Taylor estimated that the final RFP will be released “shortly,” with proposals due to NASA in mid- to late fall, followed by awards early next year.
