Boeing and NASA launched the company's Starliner astronaut taxi on a crucial uncrewed mission to the International Space Station on May 19, 2022. It touched down safely on May 25, 2022 and the company is now working on getting a crewed spaceflight ready.

Orbital Flight Test-2 (OFT-2) lifted off from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida on a United Launch Alliance Atlas V rocket. OFT-2 was originally supposed to fly in August 2021, but an issue with some valves in Starliner's propulsion system pushed things back more than eight months.

This is Boeing's second time launching Starliner on an uncrewed test flight; the first mission, OFT-1, returned to Earth early after it failed to reach the space station in December 2019. NASA conducted major reviews of the Starliner program and identified a total of 80 corrective actions that Boeing needed to take before Starliner could return to flight. 

Starliner docked with the International Space Station about 24 hours after it launched, and returned to Earth in late May with a parachute-assisted landing at White Sands Space Harbor in New Mexico.

Boeing invites students to send artwork aboard future Starliner missions

Student artists may be able to fly their handiwork to space. Boeing is offering a new opportunity, "Art in the Stars", that will bring the art (in digital form) on a future Starliner spacecraft. More details about the opportunity  are here; submissions close Dec. 16.

The first crewed flight of Starliner to the International Space Station (ISS) will happen no earlier than April 2023, a two-month delay from the last target, due to traffic at the orbiting complex.

The first Boeing CST-100 Starliner crewed spacecraft mission to the the International Space Station (ISS) will now launch in April 2023 instead of February, a NASA blog post stated Thursday (Nov. 3).

"The date adjustment deconflicts visiting spacecraft traffic at the space station as NASA and Boeing work together to achieve flight readiness," NASA officials said in a blog post Thursday (Oct. 3), adding work is ongoing to "close out the OFT-2 anomalies", referring to the second uncrewed test flight by Starliner earlier this year.

Verifications of "several critical systems" are ongoing, NASA officials added, with flight software checks and astronaut fit-checks also concluded. The two-week crewed flight will be a shakedown cruise ahead of certifying Starliner for operational flights, as soon as next year; SpaceX's Crew Dragon, in the meantime, remains the only private spacecraft certified to send humans to and from the ISS.

Boeing has losses of nearly $900 million on Starliner

As the much-delayed Starliner program targets a crewed test flight date in February 2023 to send astronauts to the International Space Station, a filing by maker Boeing Wednesday (Oct. 26) with the U.S. Securities and Exchange Commission (SEC) announced a charge of $195 million in its fiscal third quarter. That brings total losses in the program of $883 million.

The company blamed operational (post-certification) mission timeline delays for the new charge, noting previously Boeing was assuming a 2024 timeline and that has been pushed back. "The three future post certification missions ... are now assumed to be completed by 2026, based on NASA's revised launch plans," the company stated in its SEC filing.

Boeing's "picture-perfect" uncrewed Orbital Flight Test 2 concluded with a safe touchdown on May 25, following a much more troubled Orbital Test Flight 1 that finished in 2019 without reaching the ISS.

Boeing's first flight of its Starliner spacecraft for humans will wait a few more months. The flight will now launch no earlier than February 2023 due to the need to address issues identified on Orbital Flight Test-2 (OFT-2). 

Post-flight reviews revealed four main issues, Mark Nappi, Starliner vice president and program manager at Boeing, said during today's call, which will push Starliner past its expected launch of December 2022.

Boeing's Starliner capsule landed safely at White Sands Missile Range in New Mexico today (May 25) at 6:49 p.m. EDT (2249 GMT), wrapping up its uncrewed Orbital Flight Test 2 (OFT-2) mission to the International Space Station. Read our touchdown story.

The six-day-long OFT-2 was a key hurdle that Boeing had to clear before NASA certifies Starliner to carry astronauts. Certification is not guaranteed at this point, however; NASA and Boeing teams still need to analyze the data gathered during the mission.

Starliner now in view

Tracking cameras in the air and on the ground have caught their first glimpses of Starliner as it returns to Earth, picking up views of the capsule today (May 25) about eight minutes before its planned 6:49 p.m. EDT (2249 GMT) touchdown.

Starliner hits Earth's atmosphere

Starliner began feeling the effects of Earth's atmosphere today (May 25) at 6:33 p.m. EDT (2233 GMT), hitting the air at about 17 times the speed of sound. The capsule remains on track for a touchdown at New Mexico's White Sands Missile Range at 6:49 p.m. EDT (2249 GMT).

Starliner conducts de-orbit burn

Starliner conducted a 58-second de-orbit burn today (May 25) at 6:05 p.m. EDT (2205 GMT) as planned, NASA officials said. The burn slowed Starliner's velocity by 285 mph (459 kph), keeping the capsule on track for a touchdown in New Mexico at 6:49 p.m. EDT (2249 GMT). A few minutes after the burn wrapped up, Starliner jettisoned its service module, another milestone that occurred right on schedule.

Astronauts aboard the International Space Station have opened up the Starliner spacecraft and taken their first look inside. 

NASA astronaut Robert Hines was the first to enter Starliner after opening its hatch at 12:04 p.m. EDT (1604 GMT). He was followed by crewmate Kjell Lindgren and the pair quickly set up ventilation hoses, cameras and other gear inside. 

They also met Starliner's only crewmember, the mannequin Rosie the Rocketeer, who made the trip up in the commander's seat on Starliner. 

Starliner will spend about five days docked at the space station while astronauts measure its environment conduct tests to measure its performance at the station. 

It's opening day for Starliner on ISS

Boeing's Starliner successfully docked at the International Space Station at 8:28 p.m. EDT (0028 GMT May 21) as both craft sailed 271 miles above the South Indian Ocean. 

The docking came just under 22 hours after the spacecraft launched toward the station on an Atlas V rocket. 

Starliner is the second commercial spacecraft designed to ferry astronauts to reach the space station after SpaceX's Crew Dragon spacecraft. This is Boeing's first Starliner docking at the station.

NASA will hold a press conference at 9:30 p.m. EDT (0230 GMT May 21) to discuss today's docking success. You can follow that press conference on the Space.com homepage.

New Starliner docking time: 8:46 pm ET (0046 GMT)

Boeing and NASA are now targeting 8:46 p.m. EDT (0046 GMT) to dock Starliner OFT-2 to the International Space Station. That is the end of tonight's docking window.

"We do expect to make this window," Mission Control just told the ISS crew.

Starliner docking delayed for system reset

Boeing flight controllers have delayed Starliner's docking at the International Space Station another 30 minutes in order to reset the spacecraft's NASA Docking System. They'll need to retract Starliner's docking ring and reset it to clear an issue with the system, NASA officials said. 

A new exact docking time will be determined once the docking system is reset.

Starliner docking delayed again

Flight controllers have reported "a small issue" with the docking system on Boeing's Starliner spacecraft, delaying tonight's docking a bit more. 

A new docking time is expected shortly. 

Starliner just 10 meters from ISS

Boeing's Starliner is now holding about 10 meters away from the space station as flight controllers prepare for its final approach. 

The spacecraft has a new docking time of just after 8 p.m. EDT (0000 GMT), with a final thruster maneuver set for 7:57 p.m. EDT (2357 GMT).  

Starliner docking time delayed to 2nd opportunity

Boeing and NASA flight controllers have waved off the first docking opportunity for Starliner OFT-2 and are now targeting a second, backup opportunity that would call for the spacecraft to fire its thrusters for final approach at 7:53 p.m. EDT (2353 GMT). 

That means Starliner will not dock at its initially planned time of 7:10 p.m. EDT (2310 GMT). A new docking time is set for 7:57 p.m. EDT (2357 GMT). 

Starliner on approach to space station

Boeing's Starliner is now on approach to the International Space Station to make its way to a point about 10 meters away from its docking port as flight controllers assess its tracking data and performance. 

A short while ago, flight controllers gave Starliner a go to proceed after a hold to study why the spacecraft appeared to be in a position that was not at the center of its planned approach. The controllers confirmed that the position mismatch was a false indication and Starliner was in the proper position.

Starliner has conducted an "approach and retreat" maneuver, notching another milestone on the path toward its planned docking with the International Space Station less than an hour from now.

"After coming within 180 meters of @Space_Station, #Starliner performed an automatic retreat to 200 meters. The capsule has shown its ability to back away from the station in a controlled and timely manner and hold at an expected location," Boeing representatives said via Twitter this afternoon (May 20).

Docking is expected to occur around 7:10 p.m. EDT (2310 GMT). Learn more in our docking preview.

Starliner flies around space station — twice

Boeing's Starliner capsule continues to check off its pre-docking milestones on its uncrewed OFT-2 flight test to the International Space Station (ISS). 

The spacecraft successfully completed two "inbound flyaround maneuvers" this afternoon (May 20), Boeing representatives announced via Twitter. The notching of such milestones keeps Starliner on target to dock with the ISS around 7:10 p.m. EDT (2310 GMT). Learn more in our docking preview story.

Astronauts aboard the International Space Station have caught their first glimpse of Boeing's Starliner capsule.

Starliner is headed for a docking with the orbiting lab today (May 20) at around 7:10 p.m. EDT (2310 GMT), a huge part of the spacecraft's uncrewed Orbital Flight Test-2 (OFT-2) mission. And Starliner has now come within view of the station.

"She’s here! Only a small dot for now, but soon she will knock at our door. #Starliner #OFT2," the European Space Agency's Samantha Cristoforetti, who arrived at the ISS last month on SpaceX's Crew-4 mission for NASA, said via Twitter today at 4:36 p.m. EDT (2036 GMT).

Boeing's Starliner capsule has been performing well since it reached orbit on its uncrewed OFT-2 flight test to the International Space Station, company representatives say.

The capsule, which launched Thursday evening (May 19), is scheduled to dock with the orbiting lab today (May 20) around 7:10 p.m. EDT (2310 GMT). Starliner has been conducting a number of tests en route to the ISS, and they've all gone well, according to Boeing.

"Flight control teams continue to learn more about the vehicle and about how it is operating in space, and it continues to perform well as it makes its way toward the station," company representatives said in an emailed statement this afternoon. "The Guidance, Navigation and Control (GN&C) systems are performing nominally. Flight software is executing as designed. Power generation is positive."

Teams are investigating "off-nominal behavior" in a thermal cooling loop, the statement added, but Starliner continues to maintain a stable temperature despite that issue.

The statement also shed some light on the failure of two Starliner thrusters during the capsule's orbital insertion burn yesterday, glitches that the capsule overcame by firing up a backup thruster.

"The teams have concluded that a chamber drop in pressure caused the [thruster] cutoff," the statement added. "That system operated normally during all of the propulsion system demonstrations, and with redundancies in place, does not pose a risk to the rest of the flight test."

It's docking day for Boeing's Starliner OFT-2 space capsule, which is chasing the International Space Station for a planned rendezvous later tonight. 

The Starliner spacecraft is launched into orbit last night (May 19) and is scheduled to dock itself at the station tonight at 7:10 p.m. EDT (2310 GMT). You can watch the Starliner docking live starting at 3 p.m. EDT (1900 GMT).

In a press conference late Thursday, Boeing and NASA officials said the Starliner OFT-2 spacecraft is doing well in space on its uncrewed flight. During an orbital insertion burn to enter orbit about 31 minutes after liftoff, two of the capsule's 12 big thrusters failed but the remaining 10 were able to compensate for the loss. 

Boeing engineers are investigating the glitch, but it is not expected to pose an issue for today's planned docking.

The Atlas V rocket carrying Boeing's Starliner OFT-2 space capsule is now fully fueled for its launch tonight at 6:54 p.m. EDT (2254 GMT). 

"The United Launch Alliance (ULA) Atlas V rocket that will lift the vehicle into space is now fueled and configured for stable replenish," Boeing reported in a status update. "Additionally, the pad team has been cleared to re-enter Space Launch Complex-41 for spacecraft closeout operations."

The Starliner spacecraft's service module oxidation valves completed their final cycling check before launch and are working well. Stuck valves in that system are what stalled the July 2021 launch attempt for Starliner. 

"The valves have been cycled seven times since propellant loading at the factory," Boeing wrote in an update. "As part of standard prelaunch ops, at about L-30 minutes, they’ll be opened for flight."

It is launch day once again for Boeing's Starliner OFT-2 test flight to the International Space Station, with the launch time set for 6:54 p.m. EDT (2254 GMT) tonight. 

Boeing's second Starliner spacecraft and its Atlas V rocket will launch on an uncrewed test flight to space station to prove its ready to carry astronauts to and from the station for NASA. The mission has been a longtime coming. 

A December 2019 test flight launched into orbit but failed to reach the station. That was OFT-1. Then, in July 2021, an attempt to launch OFT-2 was stalled due to stuck thruster valves. Now, Boeing has addressed the valve issue and is ready to try again. 

The United Launch Alliance, which built the Atlas V rocket, rolled the booster out to its pad at Space Launch Complex 40 at the Cape Canaveral Space Force Station yesterday. The first NASA astronauts who will launch on Starliner - Sunita Williams, Mike Fincke and Butch Wilmore - told reporters Wednesday that they're excited to watch Starliner launch on its OFT-2 mission since it will set the stage for their own Crew Flight Test-1 mission in the near future. 

NASA's webcast for the launch will begin at 6 p.m. EDT (2200 GMT). You can watch the Boeing Starliner launch live through liftoff. Here's a webcast schedule from NASA:

NASA has cleared Boeing's Starliner capsule for a planned May 19 launch on Orbital Flight Test-2 (OFT-2), a crucial uncrewed mission to the International Space Station.

The decision came after a lengthy flight readiness review on Wednesday (May 11). Read more here.

OFT-2 was originally supposed to launch in August 2021, but technicians discovered that 13 of the 24 oxidizer valves in the capsule's propulsion system were stuck. Diagnosing and troubleshooting this issue ended taking about eight months.
