Watch live Tuesday: NASA launching Boeing Starliner to space station @ 1:20 pm ET

NASA and Boeing had been targeting a launch on Friday (July 30) of the uncrewed OFT-2 test flight of the new Starliner crew capsule. However, a situation on the International Space Station on Thursday (July 29) prompted a delay.

NASA officials have said the next available launch opportunity is on Tuesday (Aug. 3) at 1:20 p.m. EDT (1720 GMT). The OFT-2 docking is scheduled for 1:37 p.m. EDT (1737 GMT) on Wednesday (Aug. 4). You can watch the mission live here on Space.com, courtesy of NASA TV.

From NASA:

NASA will provide coverage of the upcoming prelaunch, launch, and docking activities for the agency’s Boeing Orbital Flight Test-2 (OFT-2) mission to the International Space Station. OFT-2 is the second uncrewed flight for Boeing’s CST-100 Starliner spacecraft as part of the agency’s Commercial Crew Program. The mission is targeted to launch at 1:20 p.m. EDT Tuesday, Aug. 3

Starliner will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. About 30 minutes after launch, Starliner will perform its orbital insertion burn to begin its daylong trip to the space station. The spacecraft is scheduled to dock to the space station at 1:37 p.m. Wednesday, Aug. 4. Launch and docking coverage will air live on NASA Television, the NASA app, and the agency’s website.

The spacecraft will carry more than 400 pounds of NASA cargo and crew supplies to the space station. It will return to Earth with more than 550 pounds of cargo, including the reusable Nitrogen Oxygen Recharge System tanks that provide breathable air to station crew members.

OFT-2 will demonstrate the end-to-end capabilities of the Starliner spacecraft and Atlas V rocket, from launch, to docking, to a return to Earth with a desert landing in the western United States. The uncrewed mission will provide valuable data toward NASA certifying Boeing’s crew transportation system for regular flights to and from the space station.

NASA has updated its coronavirus (COVID-19) policies to remain consistent with new Centers for Disease Control and Prevention (CDC) guidance. Credentialed media will receive additional details from the media operations team at NASA’s Kennedy Space Center in Florida.

‘ISS Live!’ Tune in to the space station

Find out what the astronauts and cosmonauts aboard the International Space Station are up to by tuning in to the “ISS Live” broadcast. Hear conversations between the crew and mission controllers on Earth and watch them work inside the U.S. segment of the orbiting laboratory. When the crew is off duty, you can enjoy live views of Earth from Space. You can watch and listen in the window below, courtesy of NASA.

“Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During ‘loss of signal’ periods, viewers will see a blue screen.

“Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below.”
