Boeing safely landed its first CST-100 Starliner spaceship, named “Calypso,” in New Mexico on Sunday.No astronauts flew aboard the Starliner. The mission was designed to show the vehicle, which NASA funded through its Commercial Crew Program, is safe to fly astronauts.But the Starliner suffered a major glitch with a clock shortly after launch, causing it to veer off-course.Boeing rescued the mission, which NASA officials said should achieve about 90% of its objectives despite not reaching its planned destination, the International Space Station.However, no one could say whether or not the company’s next mission would be a redo of the uncrewed test flight or the first with astronauts riding inside.Sign up for Business Insider’s transportation newsletter, Shifting Gears, to get more stories like this in your inbox.Visit Business Insider’s homepage for more stories.Boeing and NASA officials seemed proud, and perhaps a little giddy, after the company’s first new orbital-class spaceship, the CST-100 Starliner, landed with barely a scratch in New Mexico on Sunday.”You look at the landing, it was an absolute bull’s-eye. Better than, I think, anybody anticipated,” Jim Bridenstine, NASA’s administrator, said during a press conference that day. “That’s good for the agency, it’s good for Boeing, and it’s good for the United States of America.”But just two days before, the autonomous spacecraft — which carried no people on its maiden flight — suffered from a critical timing error that, without intervention from mission control, likely would have ended with the loss of the uncrewed Starliner and its cargo of food and Christmas presents bound for the International Space Station.More importantly, the Orbital Flight Test mission was designed to show NASA the spacecraft is safe to fly astronauts on a follow-up test flight, ostensibly planned for mid-2020.”It’s disappointing for us,” Jim Chilton, the senior vice president of Boeing’s Space and Launch division, said of the error just after launch on Friday.Here’s what happened during the historic mission and why both Boeing and NASA officials now, after landing “Calypso,” as astronauts have named the space-worthy ship, seem surprisingly upbeat about its performance.

Boeing designed the CST-100 Starliner to fly up to seven passengers. NASA funded the work with a $4.2 billion contract.

The money comes from the Commercial Crew Program, which NASA started 2010. The goal: Have companies, not the US government, build new spaceships to reach the International Space Station.

NASA desperately needs those commercial spaceships because it retired its fleet of space shuttles in July 2011.

Ever since then, NASA has solely — and uncomfortably — relied on Russia to ferry US astronauts to and from orbit inside that nation’s Soyuz spacecraft. A single round-trip ticket now costs NASA more than $80 million.

Help is on the way, though. Out of a dozen companies, Boeing and SpaceX made it through NASA’s competition with two independent spaceship designs.

Before Boeing’s Starliner vehicle can fly astronauts, though, NASA requires a series of test flights and demonstrations.

NASA requires Starliner to fly astronauts to safety in the unlikely event of a rocket-launch failure. So Boeing developed new engines …

… And tested them on a full escape system in November. The test showed Starliner can automatically blast away from impending disaster.

Though the engines initially leaked, and the parachutes took years to perfect — such a system hadn’t been used since the Apollo program decades ago — Boeing eventually persevered.

These and many other subsystems culminated in the first-ever orbital launch of a Starliner at 6:36 a.m. ET on December 20.

Nobody was inside except a mannequin named Rosie. There was also some food, Christmas presents, and other cargo for astronauts aboard the space station.

The spaceship rode toward space atop an Atlas V rocket, built by United Launch Alliance. It lifted off from Cape Canaveral, Florida.

To viewers of a NASA TV livestream, the flight seemed to be smoothly for more than half an hour.

The Starliner separated from the Atlas V after about 15 minutes.

But mission control knew something was wrong shortly after that. About 31 minutes into the mission, Starliner was supposed to have automatically fired its engines to set a course for the space station — but it never did.

When the rocket disconnected from the Starliner, the ship’s clock was 11 hours too far ahead. This caused the ship’s autonomous navigation system to fire small reaction-control thrusters and adjust its position in space —for a phase of the mission it had not yet reached.

And possibly because Starliner wasn’t in the right position, it had trouble connecting with NASA satellites: Mission Control couldn’t immediately override the autonomous system and tell the ship to fire its main engines for orbit.

As a result, the Starliner burned through about 25% of its fuel before Mission Control finally took remote-control of the ship. There wasn’t enough fuel to reach the space station — only rescue the ship into a stable orbit and prevent it from crashing to Earth.

It was a tense moment for everyone on the mission, though officials said human pilots could have made a big difference. “Had we had an astronaut on board, we very well may be at the International Space Station right now,” Bridenstine said on Sunday.

That’s because — according to NASA managers, Boeing officials, and astronauts themselves — a person would have seen the ship had missed a critical engine burn.

At that point, someone would have used Starliner’s manual controls to bypass the autopilot and take over the flight.
