Sierra is a cash poor company right now, and that is apparently part of the problem. They are short on resources to complete testing and make the necessary fixes in a timely manner. This is why Eric Berger has become so skeptical about it.

They are said to be seriously exploring an IPO within the coming months to resolve the resource problem, though the departure of CEO Tom Vice in January has created a lot of uncertainty about those plans. I don’t know how it will turn out, but I share the hope that they can, in spite of all, get Tenacity into orbit. It will be a uniquely useful little vehicle if they can ever get it operational.

I was really rooting for them.

”SO need to get Tenacity flying sooner, to make use of that port.” That’s the problem. Tenacity is not ready. Eric Berger has publicly stated he’s not sure it will ever be ready. ”Maybe add a PMA/IDA to one of the berthing ports to make room!” There aren’t any more.

With only 4 docking ports on the ISS, 2 PMA/Docking ports for Crew Dragon, Cargo Dragon, and CST-100 and always need a Crew Dragon on station, so basically on port free at most. The berthing ports, Cygnus and Tenacity will use. SO need to get Tenacity flying sooner, to make use of that port.

Maybe add a PMA/IDA to one of the berthing ports to make room!
