Members of NASA\u2019s independent safety advisory panel on Thursday cautioned the space agency not to rush toward a crew test flight of Boeing\u2019s troubled Starliner spacecraft, and voiced concerns about final certification of the capsule\u2019s parachutes and Boeing staffing levels on the program.<\/p>\n

The safety advisors also said there are \u201cobvious safety concerns\u201d about SpaceX\u2019s plan to launch the giant Starship rocket from pad 39A at the Kennedy Space Center, the same facility used for crew missions to the International Space Station.<\/p>\n

Boeing plans to launch a redo of a problem-plagued test flight of its Starliner crew capsule next week. The mission \u2014 called Orbital Flight Test-2, or OFT-2 \u2014 will not carry astronauts. But if it goes well, the OFT-2 mission will pave the way for the next Starliner launch to ferry a crew to the space station for a final demonstration mission \u2014 called the Crew Flight Test, or CFT \u2014 before NASA and Boeing declare the new commercial vehicle ready for operations.<\/p>\n

Developed in a public-private partnership, the Starliner spacecraft will give NASA a second human-rated capsule capable of ferrying astronauts to and from the space station, alongside SpaceX\u2019s Dragon spaceship, which launched with a crew for the first time in May 2020.<\/p>\n

With SpaceX now providing regular crew transportation services to the space station, NASA officials had time to wring out technical issues with the Starliner spacecraft. Nevertheless, NASA is eager to have two crew transportation providers to avoid again relying on Russia\u2019s Soyuz spacecraft for astronaut flights in the event SpaceX runs into any significant delays.<\/p>\n

\u201cThe panel is pleased that from all indications there is no sense of needing to rush to CFT,\u201d said David West, a member of the Aerospace Safety Advisory Panel, in a public meeting Thursday. \u201cThe view that was consistently expressed to us (from NASA) is that the program will proceed to CFT when, and only when, they\u2019re ready. Of course, the best path to CFT will be a successful OFT-2.\u201d<\/p>\n

NASA has signed a series of contracts with Boeing, valued at more than $5 billion, since 2010 for Starliner development, test flights, and operations. The contracts include agreements for six crew rotation flights to the space station \u2014 each with a four-person crew \u2014 following the completion of the OFT-2 mission and the shorter-duration Crew Flight Test with astronauts on-board.<\/p>\n

But the Starliner program has faced years of delays. Software woes prevented the spacecraft from docking at the space station on the OFT-1 mission in 2019, forcing Boeing to put together a second unpiloted test flight at its own expense. The OFT-2 mission was on the launch pad last August, ready for liftoff on top of a United Launch Alliance Atlas 5 rocket, when engineers noticed 13 oxidizer isolation valves in the Starliner spacecraft\u2019s propulsion system were stuck in the closed position.<\/p>\n

After nine months of testing, investigations, and a swap to a new propulsion module, Boeing transferred the Starliner spacecraft back to ULA\u2019s rocket hangar May 4 for lifting on top of an Atlas 5 rocket, ready for another go at launch. Read our previous story about the valve repairs.<\/p>\n

West said Thursday that NASA managers have signed off on the oxidizer valve fix for the OFT-2 mission, but noted \u201cthere is some question as to whether a valve redesign will be required for future flights after OFT-2.\u201d He also said managers approved \u201cflight rationale\u201d for issues with a high pressure latch valve on the Starliner command module propulsion system, a separate issue from the oxidizer valves in the service module.<\/p>\n

\u201cAlso, there\u2019s concern that the certification of Boeing parachutes is lagging behind,\u201d West said.<\/p>\n

He also noted a \u201csignificant programmatic concern\u201d with the limited number of human-rated Atlas 5 rockets remaining in ULA\u2019s inventory. ULA has 24 more Atlas 5 rockets to fly before retiring the rocket in favor of the less expensive, more powerful Vulcan Centaur rocket.<\/p>\n

Eight of those 24 rockets are already allocated to the Starliner program, enough to fulfill Boeing\u2019s contractual requirement to NASA, which includes two more test flights and six operational crew rotation missions to the space station.<\/p>\n

ULA\u2019s new Vulcan rocket has not yet flown.<\/p>\n

\u201cAnother factor is that the Vulcan launch vehicle slated to replace the Atlas 5 for Starliner launches needs to be certified for human spaceflight, and the process of getting that certification could take years,\u201d West said.<\/p>\n

West, a longtime engineering safety manager and examinations director at the Board of Certified Safety Professionals, said general concerns about the NASA and contractors workforce across the agency\u2019s human spaceflight program have \u201cparticular significance in Boeing\u2019s case.<\/p>\n

\u201cThe panel has noted that Boeing staffing levels seem to be especially low,\u201d West said. \u201cThe panel will be monitoring the situation in the near future to see what impact if any this could have on the existence or mitigation of any safety risks.<\/p>\n

\u201cWhile we don\u2019t want to see and undue rushing toward the CFT launch, Boeing should ensure that all available resources are applied to meet a reasonable schedule and avoid unnecessary delays,\u201d West sad.<\/p>\n

\u201cWe are certainly behind the idea of not launching until (it) is ready, until all safety has been taken care of,\u201d said Mark Sirangelo, another member of the safety panel. \u201cAt the same time, if the delays are caused by a lack of resources being applied to the program, that has significant impacts, or may have significant effects, to the NASA schedule for its return to the moon and many other things that are going to fan out from those delays.\u201d<\/p>\n

NASA and Boeing officials have declined to set a target schedule for the Crew Flight Test, only saying that preparations on the capsule for the first astronaut mission were on track to have the vehicle ready for launch by the end of this year. The schedule  for the Crew Flight Test will largely hinge on the outcome of the OFT-2 mission.<\/p>\n

SpaceX, NASA\u2019s other commercial crew contractor, has accomplished five crew launches for NASA, plus two all-private astronaut missions using the company\u2019s fleet of Dragon spacecraft.<\/p>\n

Officials said last year that SpaceX would end production of new Dragon capsules after building four human-rated vehicles. The fourth and newest member of the fleet launched for the first time last month. Each Dragon spacecraft is designed for at least five flights, and SpaceX and NASA could certify the capsule for additional missions.<\/p>\n

\u201cWe are definitely concerned about whether requirements for transporting astronauts to and from the ISS through its remaining life, whatever that is, can be met without any additional Dragons,\u201d West said. \u201cIt would be advisable to conduct parametric studies to inform and support relevant decisions about whether more Dragon capsules are required.<\/p>\n

\u201cThe Dragon launch rate continues, however, and measures are being taken to keep the launch rate up,\u201d West said. \u201cSome of these measures may include deferring preventive maintenance and reusing Dragon several times. \u201cThe panel will be watching closely to see if these measures can be implemented without increasing risk.<\/p>\n

\u201c\u2018It should be noted, by the way, that there\u2019s a huge amount of data coming from all these SpaceX launches,\u201d West said. \u201cWhile the data can benefit NASA, we think the care needs to be taken to keep from becoming overwhelmed by too much data.\u201d<\/p>\n

In February, NASA ordered three more crew rotation missions from SpaceX, adding to the six flights on the original commercial crew contract. Once Starliner is operational, NASA wants to alternate crew rotations every six months between Boeing and SpaceX, giving each provider one NASA astronaut flight per year.<\/p>\n

West added that SpaceX plans to eventually launch the huge next-generation Starship rocket, currently under development in South Texas, from the Kennedy Space Center could pose a risk to the Falcon 9 and Dragon launch facility at pad 39A.<\/p>\n

\u201cOne possible option that has been identified for launching Starship is from a planned new facility within the physical boundaries around pad 39A at the Kennedy Space Center, where Dragons are launched from,\u201d West said. \u201cThere are obvious safety concerns about launching the large, and as yet unproven, Starship in such close proximity, reportedly only 300 yards or so, from another pad, let alone the path so vitally necessary for the commercial crew program.\u201d<\/p>\n

Pad 39A is also the only launch facility currently capable of launching SpaceX\u2019s Falcon Heavy rocket, necessary to haul some heavier NASA and U.S. military spacecraft into orbit.<\/p>\n

The Starship and its gigantic Super Heavy booster stage combine to stand nearly 400 feet (120 meters) tall. The system is designed to be fully reusable, and SpaceX plans to vertically land the Starship booster and upper stage back at the launch site.<\/p>\n

SpaceX is finishing work on a Starship launch pad in South Texas, but the Federal Aviation Administration is reviewing the environmental impacts of SpaceX\u2019s operations at the site before issuing a commercial launch license for the first full-up Starship orbital test flight.<\/p>\n

NASA awarded SpaceX a $2.9 billion contract last year to develop a version of the Starship vehicle to land astronauts on the moon.<\/p>\n

\u201cIn conclusion, I\u2019d just like to say that these are extremely complex times for CCP,\u201d West said, referring to NASA\u2019s commercial crew program. \u201cAs the Starship launch site issued demonstrates, there are numerous external but related considerations to be made. One thing that continues to be clear, though, is that it\u2019s still very important to reach the point where NASA has two viable CCP providers.\u201d<\/p>\n
