Some statements from NASA:
> After the more recent debris sightings, NASA and SpaceX now acknowledge that improvements are needed. The agency recently stated that initial studies expected the trunk to burn up fully upon reentry. “NASA and SpaceX will continue exploring additional solutions as we learn from the discovered debris,” NASA stated.
“We did analysis back before Demo-2 and clearly the models don’t deal with the trunk very well,” Steve Stich, NASA commercial crew program manager, said in an interview after a Starliner briefing ahead of that mission’s June 6 launch. He said it’s likely because of the composite materials used in the trunk. “It’s almost like a thermal protection system.”
The solution he said NASA and SpaceX are looking at involves changing deorbiting procedures. Currently, the trunk is released before the capsule performs its orbit burn. That means the trunk can remain in orbit for months before making an uncontrolled reentry.
Instead, Stich said engineers are examining doing the deorbit burn and then releasing the trunk. That would provide more control of where the trunk reenters, ensuring that any debris that survives reentry lands in unpopulated regions.
“We’re in the process of doing that work right now,” he said. “I would love to have something in place next year if we can, but we’ve got to do all the right analysis. We’ve got make sure that it’s safe for the crew.”
