NASA safety panel has lingering doubts about Boeing Starliner quality control

WASHINGTON — Members of a NASA security panel expressed continued concern about high quality points with Boeing’s business crew spacecraft whereas cautiously supporting SpaceX’s plans to fly reused spacecraft on future crewed missions.

Throughout a July 23 teleconference by the Aerospace Security Advisory Panel, members mentioned a number of critiques of points with the uncrewed flight of Boeing’s CST-100 Starliner spacecraft final December. NASA introduced July 7 it had accomplished its critiques of that Orbital Flight Take a look at (OFT) mission, which resulted in 80 suggestions particular to the flight and several other extra from a separate “high-visibility shut name” overview carried out earlier this yr by NASA.

All the suggestions particular to Starliner, together with software program points that accounted for almost all of these suggestions, will have to be accomplished and permitted earlier than a second OFT mission, stated Don McErlean, a member of the panel. He famous NASA has augmented its business crew software program workforce “to considerably enhance perception and oversight” into the automobile’s software program growth.

These actions “ought to considerably scale back the chance to OFT, Crew Flight Take a look at, and additional [commercial crew program] flights,” he stated. Crew Flight Take a look at, or CFT, can be a crewed take a look at flight of the spacecraft carrying two NASA astronauts and one Boeing astronaut.

Nevertheless, he stated the panel nonetheless had considerations concerning the total Starliner program. “Regardless of this progress, which is particular and, the truth is, measurable, the panel continues to be involved about high quality management issues that seemingly have plagued the Boeing business crew program,” he stated. “That is nonetheless a difficulty that the panel will proceed to look at carefully as OFT and, later, CFT, are carried out.”

The panel made no particular suggestions past asking NASA’s business crew program to make sure there’s a stability between schedule and work on the automobile. NASA has not set a schedule for the second OFT mission, however has instructed the flight may happen late this yr, with CFT following within the spring of 2021.

Patricia Sanders, chair of the panel, was skeptical that Starliner might be able to fly NASA astronauts quickly, concluding it was “nonetheless a methods off earlier than we now have two absolutely functioning, operational autos.”

Issues concerning the software program points with Starliner have prolonged to different NASA packages. Susan Helms, a former astronaut who’s a member of the panel, stated NASA’s exploration programs growth (ESD) packages are “very engaged” within the overview, notably concerning software program growth suggestions that would apply to its personal packages.

NASA “is making use of the notable classes realized from that investigation to the software program program administration of the ESD program,” she stated, though the small print about effort have been deferred to a future panel assembly.

SpaceX reusability

Whereas the security panel was crucial of Boeing’s work on business crew, it praised SpaceX for the success up to now of its Demo-2 Crew Dragon mission to the Worldwide Area Station. “NASA and SpaceX are most definitely to be congratulated for the Demo-2 launch,” McErlean stated.

That mission, he acknowledged, just isn’t but over, with NASA planning a splashdown off the Florida coast Aug. 2, relying on climate situations. McErlean famous that this spacecraft has a “very restricted wind margin” that can complicate the touchdown. In consequence, NASA now has recognized seven places off the Florida coast, up from three initially recognized. They’re positioned offshore from Cape Canaveral, Daytona Seashore, Jacksonville, Panama Metropolis, Pensacola, Tallahassee and Tampa.

A profitable touchdown for Demo-2 will enable NASA and SpaceX to show their consideration to the primary operational Crew Dragon mission, Crew-1. NASA stated in a July 22 media advisory it anticipated a launch no sooner than late September.

The Crew-1 mission will use each a brand new Falcon 9 booster and Crew Dragon spacecraft, however later missions will use beforehand flown {hardware}. NASA permitted a contract modification in Could that enables SpaceX to reuse boosters and capsule beginning on the Crew-2 mission, which might launch in 2021.

McErlean stated NASA expects that the Crew-2 will use the Falcon 9 booster that launches Crew-1, and the capsule from the continuing Demo-2 mission.

“That is the primary time that we are going to have reuse of {hardware} in a human-carrying capsule,” he stated. “On this case, Crew-2 might be absolutely using the SpaceX reuse philosophy.”

Permitting boosters and spacecraft to be reflown on crewed missions would require adjustments to NASA spacecraft certification procedures, he cautioned, in addition to dealing with SpaceX’s method to “consistently evolving” automobile designs to include enhancements and different adjustments.

“Given the SpaceX method to {hardware} upgrades, NASA has to resolve by what processes it should proceed to observe automobile and system adjustments to make sure that these adjustments nonetheless stay in an appropriately licensed security posture for human spaceflight operations,” he stated.
