A second unpiloted take a look at flight of Boeing’s Starliner crew capsule — ordered after an preliminary demonstration mission fell in need of reaching the Worldwide Area Station — is now scheduled for launch from Cape Canaveral in August or September, leaving little margin to conduct the spaceship’s first flight with astronauts earlier than the tip of the 12 months.
Boeing and NASA officers confirmed the brand new schedule in current statements, following a delay earlier the 12 months from the take a look at flight’s earlier goal launch date of April 2. Managers blamed that schedule slip on delays in performing software program testing to organize for the upcoming take a look at flight, together with difficulties stemming from a winter storm in February that impacted Boeing’s software program lab in Houston.
The CST-100 Starliner spacecraft is one in every of two industrial crew ships developed by U.S. business underneath contract to NASA. SpaceX is NASA’s different industrial crew contractor, and that firm’s Crew Dragon spacecraft started flying astronauts to the station final 12 months.
Boeing’s Starliner, in the meantime, continues to be months away from it initially-unplanned second unpiloted take a look at flight, and a crew take a look at flight is predicted a minimum of a number of months after that.
Officers mentioned the exterior concerns drove the schedule to launch Boeing’s second Starliner Orbital Flight Check, or OFT-2 mission, within the August/September timeframe.
The Starliner spacecraft makes use of the identical area station docking ports as SpaceX’s Dragon crew and cargo ships. A type of ports is at the moment taken by a Crew Dragon capsule, and each ports might be occupied for a number of days later this month with the handover of 1 Crew Dragon mission to the following.
SpaceX’s subsequent Dragon cargo mission is scheduled to launch June three and can spend a couple of month-and-a-half docked with the area station to ship contemporary provides, experiments, and a brand new pair of photo voltaic arrays. That precludes a Starliner docking earlier than the second half of July.
The operational crew and cargo missions get precedence over take a look at flights within the area station’s schedule.
NASA and Boeing officers additionally need to discover a window in United Launch Alliance’s Atlas 5 launch schedule at Cape Canaveral Area Power Station. Not like SpaceX, which launches Crew Dragon missions by itself Falcon 9 rockets, Boeing contracted with ULA to spice up Starliner crew capsules into orbit.
ULA is a 50-50 three way partnership between Boeing and Lockheed Martin, however it operates as an unbiased firm and has different clients. The U.S. Area Power at the moment has payloads scheduled to launch on three Atlas 5 missions in Could, June, and August, carrying a brand new billion-dollar army missile warning satellite tv for pc, a menagerie of tech demo experiments, and two area surveillance payloads.
Boeing beforehand had an early September launch slot booked with ULA for the Starliner’s Crew Flight Check — the capsule’s first demonstration mission with astronauts — when the OFT-2 mission was set for launch earlier this 12 months. That launch slot is now obtainable for the OFT-2 mission, and officers aren’t ruling out transferring up the OFT-2 launch to August if one of many Area Power delays one in every of its missions.
The Atlas 5 launch pad might be tied up in late September by means of a lot of October with preparations to launch NASA’s robotic Lucy spacecraft on a marathon journey by means of the photo voltaic system to review asteroids. Lucy has a 23-day planetary launch window opening Oct. 16, and NASA will give the asteroid probe precedence over the company’s different missions.
Steve Stich, NASA’s industrial crew program supervisor, mentioned final week the Starliner spacecraft assigned to the OFT-2 mission is in “fine condition” because it undergoes preparations in a facility at NASA’s Kennedy Area Heart in Florida.
“It’s nearly prepared for launch,” Stich mentioned.
In a press release, Boeing mentioned it will likely be “mission prepared” in Could in case a gap arises within the Atlas 5 launch schedule.
“The Starliner crew has accomplished all work on the OFT-2 car apart from exercise to be performed nearer to launch, resembling loading cargo and fueling the spacecraft,” Boeing mentioned. “The crew additionally has submitted all verification and validation paperwork to NASA and is finishing all Impartial Overview Group beneficial actions together with people who weren’t obligatory forward of OFT-2.”
Boeing is taking extra time to finish software program testing on the Starliner spacecraft whereas officers look ahead to a gap within the area station schedule and ULA’s launch manifest, based on Stich. Boeing mentioned in a press release it expects to finish software program simulations, together with end-to-end confidence and integration testing, earlier than the tip of April and can present the outcomes to NASA reviewers.
Investigators blamed a software program error for the OFT-1 mission’s failure to dock with the area station in 2019. A mission timer was wrongly programmed, inflicting the spacecraft to suppose it was in a special mission part when it separated from its Atlas 5 rocket after an otherwise-successful liftoff from Cape Canaveral.
The error triggered the Starliner capsule to burn extra propellant than anticipated, consuming the gas it wanted to maneuver towards the area station. Mission managers elected to finish the mission early, and the spacecraft landed in New Mexico.
Assuming the OFT-2 mission will get off the pad in late summer season, Stich mentioned the Starliner’s Crew Flight Check may take off “towards the tip of the calendar 12 months.”
The Crew Flight Check will carry NASA astronauts Butch Wilmore, Mike Fincke, and Nicole Mann to the area station. They’ll fly on the identical reusable Starliner spacecraft that launched and landed in December 2019 on Boeing’s first Orbital Flight Check, whereas the OFT-2 mission will fly on an unused car.
Boeing mentioned its groups are making ready for the “shortest turnaround time potential” between the OFT-2 mission and the Crew Flight Check. Wilmore, Fincke, and Mann lately suited up and climbed aboard the spacecraft set to fly the OFT-2 mission for all times assist and communications methods checkouts.
As soon as Boeing accomplishes the 2 remaining Starliner take a look at flights, NASA will certify the capsule for normal crew rotation missions to the area station, simply because the company did for SpaceX’s Crew Dragon final 12 months.
NASA has practically $7 billion in contracts with Boeing and SpaceX protecting the event of the 2 industrial crew spaceships, and 6 operational crew rotation flights by every firm.
With Boeing’s delays, SpaceX is prone to have launched 4 Crew Dragon missions with NASA astronauts — a take a look at flight and three operational launches — earlier than the Starliner flies with individuals for the primary time.
Steve Jurczyk, NASA’s appearing administrator, mentioned the company initially deliberate to alternate industrial crew missions between Boeing and SpaceX.
“The plan proper now could be to alternate — SpaceX, Boeing, SpaceX, Boeing — nonetheless, the primary Boeing crew flight is delayed, and we’re going to almost definitely … have 4 crew flights with SpaceX earlier than the crew take a look at flight with Boeing,” Jurczyk mentioned Tuesday. “So we could need to relook at that, however we haven’t gotten round to speaking about that but.”
NASA may even quickly get thinking about how and when to obtain extra industrial crew missions to satisfy the area station’s necessities past 2024, he mentioned. However these talks are nonetheless to return.
“We actually haven’t talked intimately about how we’re going to maneuver ahead past the present contracts and commitments,” Jurczyk mentioned in an interview with Spaceflight Now.
