NASA has warned SpaceX and Boeing Co of design and safety concerns for their competing astronaut launch systems, according to industry sources and a new government report, threatening the US bid to revive its human spaceflight program later this year.

NASA is paying SpaceX $2.6 billion and Boeing $4.2 billion to build rocket and capsule launch systems to return astronauts to the International Space Station from US soil for the first time since America’s Space Shuttle program went dark in 2011.

Just ahead of the first scheduled un-manned test flight slated for March 2 under NASA’s multibillion-dollar Commercial Crew Program, NASA’s safety advisory panel cited four “key risk items” in its 2018 annual report earlier this month.

For Boeing, they include the capsule’s structural vulnerability when the heat shield is deployed. For SpaceX, the report mentioned the redesign of a SpaceX rocket canister following a 2016 explosion and its “load and go” process of fueling the rocket with the crew already inside the capsule. “Parachute performance” remained an issue for both companies.

“There are serious challenges to the current launch schedules for both SpaceX and Boeing,” the report said.

Two people with direct knowledge of the program told Reuters that the space agency’s concerns go beyond the four items listed, and include a risk ledger that as of early February contained 30 to 35 lingering technical concerns each for SpaceX and Boeing. Reuters could not verify what all of the nearly three dozen items are. But the sources familiar with the matter said the companies must address “most” of those concerns before flying astronauts and, eventually, tourists to space.

The NASA risk database is updated routinely during the course of NASA’s stringent certification process, which includes data collection, tests and collaboration with SpaceX and Boeing, the people said. The Boeing and SpaceX systems have already been delayed several times in recent years, which is common in this sector given the complexity of building multibillion-dollar spacecraft capable of shedding earth’s gravity.

NASA spokesman Joshua Finch deferred all technical questions on Boeing and SpaceX systems to the companies, citing confidentiality, but said: “Flying safely always takes precedence over schedule.”

Boeing spokesman Josh Barrett said the company “closed out” the capsule’s structural vulnerability risk when it completed its structural test program in January. While Boeing is working through a number of other issues, they “are not driving any major architectural system changes.”

“Our numbers show we are exceeding NASA’s safety requirements,” said Barrett.

SpaceX spokesman James Gleeson said the company, working with NASA, has developed “one of the safest, most-advanced human spaceflight systems ever built.”

“There is nothing more important to SpaceX than safely flying crew,” said Gleeson, calling it “core to our company’s long-term goal of enabling access for people who dream of flying to space.”

Founded by Tesla Inc Chief Executive Elon Musk, SpaceX has cut the cost of rocket launches with its pioneering reusable rocket technology, while Boeing traces its space business back to the first US human space missions of the 1960s and is also the world’s largest planemaker.

The clock is ticking. The US has been paying Russia about $80 million per ticket for a ride to the International Space Station, a $100 billion orbital research laboratory that flies about 250 miles (402 km) above Earth.

There are no seats available for US crew on the Russia spacecraft after 2019 given production schedules and other factors. NASA said last week it was considering paying for two more seats to the space station for this fall and spring 2020 to ensure US access.

The NASA plan for extra seats came a week after its safety panel said Congress should come up with a “mitigation plan” in case delays threaten US access to the space station – echoing earlier concerns from the US Government Accountability Office.

NASA is set to conduct a flight readiness review on Friday for SpaceX’s mission without a crew on March 2. NASA will decide whether to approve the test flight without a crew, while SpaceX addresses the issues raised for a human mission.

Parachute Weaknesses

Three people familiar with the project say the US space agency has identified some design discrepancies between earlier SpaceX capsules designed to haul cargo to the International Space Station, and a newer version designed to carry humans. Some of the risks – such as those identified in the designs of the enormous parachutes that deploy when the capsule plummets back to Earth at supersonic speeds – are uncommon given how close SpaceX is to test flights, two of the people said.
