Timing is everything, especially in spaceflight, and that’s where Boeing’s
Starliner first had trouble. Thanks to a software glitch, Starliner
incorrectly set its internal clock hours before it launched, which meant
that after it separated from the rocket and reached space, the capsule
missed the moment it needed to fire some thrusters and push itself into the
right orbit. In a cruel twist, mission control lost contact with Starliner
just then, due, it seems, to interference from radio noise on Earth,
possibly from cellphone towers. By the time engineers could command
Starliner again, the capsule, disoriented and idling, had used up too much
fuel to finish its climb toward the ISS.
With no choice but to return Starliner home, Boeing engineers started
combing through the software and found another issue. Before Starliner
begins its final descent to Earth, it must shed a service module that helped
nudge it toward the atmosphere. But the way the software sequence was set
up, the thrusters on this module wouldn’t have fired correctly. A rocky
separation could have destabilized Starliner, causing it to tumble. The two
spacecraft could’ve even bumped into each other, in which case the impact
could have damaged the heat shield. Starliner needs that shield to survive
the fiery drop of reentry, with astronauts on board or not.
“It’s hard to say where the service module would have bumped, but nothing
good can come from those two spacecraft bumping,” Chilton told me.
Boeing engineers rewrote the software and sent the new version to Starliner
barely three hours before the capsule touched down in New Mexico. If they
hadn’t intervened, NASA says, Starliner could have been lost. | d**s
