SpaceX Delays First Crewed Flight Of Its Dragon Capsule For NASA (theverge.com)
NASA says the first crewed test flight of SpaceX's Dragon vehicle has been delayed until May 2018. From a report on The Verge: In the wake of its September 1st rocket explosion, SpaceX has officially delayed the first crewed flight of its Crew Dragon vehicle -- the capsule that the company is building to take NASA astronauts to and from the International Space Station. Originally planned for late 2017, the first flight of the Crew Dragon with people on board is now slated to take place in May of 2018, according to a NASA blog post. Prior to that flight, SpaceX will perform a demonstration mission of Crew Dragon in November 2017 -- a flight that won't include any astronauts. There had been heavy speculation that the flight would be delayed following the accident, in which a Falcon 9 rocket exploded as it was being fueled on a Florida launch pad. And SpaceX says the move was made as the company finalizes its investigation into the accident. "As this investigation has been conducted, our Commercial Crew team has continued to work closely with NASA and is completing all planned milestones for this period," SpaceX said in a statement to The Verge. "We are carefully assessing our designs, systems, and processes taking into account the lessons learned and corrective actions identified. Our schedule reflects the additional time needed for this assessment and implementation."
The tunnel crack problem was discovered in Jan 2015 so they have had awhile to work on it. This was first revealed on 1 Sept 2016 in the Commercial Crew program update.
'NASA Program officials anticipate SpaceX will encounter additional delays on the path to certification. For example, in January 2015, the tunnel that provides a passageway for astronauts and cargo between the Dragon and the ISS was reported to have cracked during the heat treatment phase of the manufacturing process. As a result, SpaceX delayed qualification testing by approximately one year to better align the tests as SpaceX moves toward certification. SpaceX has also experienced ongoing issues with stress fractures in turbopumps that must be resolved prior to flight.23 Additionally, SpaceX has not yet completed parachute system level testing which may reveal issues that would require redesign that could further delay the test flights. Accordingly, we anticipate additional schedule slippage and do not expect certified flights by SpaceX earlier than late 2018.'
Today's vices may be tomorrow's virtues.
Boeing had earlier said they would be delayed in providing a man-ready CST-100 spacecraft. Boeing's spacecraft is supposed to be compatible with several rockets (including the SpaceX Falcon 9) but probably would launch on an Atlas V. Sierra Nevada, well I'm having trouble taking them seriously and always have, there's no chance that Dream Chaser will be ready before the others. Nor will Blue Origin.
