NASA’s Boeing Orbital Flight Test-2 will test the end-to-end capabilities of the company’s CST-100 Starliner spacecraft from launch to docking to a return to Earth in the desert of the western United States. The flight test will provide valuable data toward NASA certifying Boeing’s crew transportation system for regular crewed flights to and from the International Space Station. OFT-2 will build on the objectives achieved during Starliner’s initial flight test, including:

In-orbit operation of the avionics, docking system, communications and telemetry systems, environmental control systems, solar arrays and electrical power systems and propulsion systems;
Performance of the guidance, navigation and control systems of the Starliner and Atlas V through ascent, on-orbit, and entry;
Acoustic and vibration levels, and loads across the Starliner exterior and interior;
Launch escape trigger monitoring; and
Performance of the Starliner system end-to-end mission operations.

These objectives are intended to demonstrate all of Starliner’s systems and capabilities except for those requiring a human onboard to test.

For this flight, Starliner will carry more than 500 pounds of NASA cargo and crew supplies to the space station. After a successful docking, the spacecraft will spend five to 10 days aboard the orbiting laboratory before returning to Earth. The spacecraft will return with nearly 600 pounds of NASA cargo, including reusable Nitrogen Oxygen Recharge System tanks that provide breathable air to station crew members.

Good afternoon from Kennedy Space Center in Florida, and welcome to live launch coverage of NASA’s Boeing Orbital Flight Test-2 (OFT-2) to the International Space Station, launching in a little over an hour. Boeing’s CST-100 Starliner spacecraft sits atop a United Launch Alliance Atlas V rocket poised on the launch pad ready to go at nearby Space Launch Complex-41 on Cape Canaveral Space Force Station.

OFT-2 is an uncrewed flight test of the company’s Starliner spacecraft for NASA’s Commercial Crew Program. Liftoff is scheduled for 6:54 p.m. EDT during an instantaneous launch window.

The countdown is currently proceeding according to schedule. Fueling of the Atlas V rocket began a little after noon EDT today. The first stage booster’s RD-180 engine, containing two thrust chambers, was fueled with Rocket Propellant-1, a highly purified kerosene. The Centaur second stage was fueled with liquid hydrogen and liquid oxygen. Fueling of the rocket was completed about two hours later.

Stay with us here for coverage as the countdown continues towards launch. Watch the coverage live on NASA TV starting at 6 p.m. EDT. More details about the flight test and NASA’s Commercial Crew Program can be found in the online press kit and by following the @commercial_crew on Twitter and commercial crew on Facebook.

Meteorologists with the U.S. Air Force 45th Weather Squadron continue to predict an 80% chance of favorable weather for launch this afternoon. The primary concerns for launch day are the cumulus and anvil cloud rules violations during the instantaneous launch window.

Starliner Joins Atlas V at Space Launch Complex-41

On Wednesday, May 4, Boeing’s CST-100 Starliner was joined with the rocket that will launch the spacecraft on its way to the International Space Station on an uncrewed flight test for NASA’s Commercial Crew Program.

During the operation, Starliner rolled out of the Commercial Crew and Cargo Processing Facility (C3PF) at NASA’s Kennedy Space Center in Florida and made its way to Space Launch Complex-41 (SLC-41) at Cape Canaveral Space Force Station in preparation for the company’s second uncrewed Orbital Flight Test (OFT-2)

Starliner was raised and carefully placed onto the rocket and now is fully assembled and ready for an integrated systems test, a tip-to-tail electrical check of the 172-foot-tall Atlas V and Starliner stack.

OFT-2 is scheduled to launch Thursday, May 19, to demonstrate the system’s human transportation capabilities.

About 24 hours after launch, Starliner will rendezvous and dock to the space station and then return to Earth five to 10 days later. The test is the last flight before the Starliner system launches American astronauts on the Crew Flight Test (CFT) to the microgravity laboratory – the spacecraft’s first flight test with crew on board. Potential launch windows for CFT are under review and will be determined after a safe and successful OFT-2.

Starliner Returns to Factory, Preparations Underway to Resolve Valve Issue

Teams from Boeing and United Launch Alliance (ULA) safely returned the CST-100 Starliner to its production facility in Florida on Aug. 19 for continued work on the spacecraft’s service module propulsion system.

The Starliner Orbital Flight Test-2 spacecraft was removed from its Atlas V rocket inside the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida and returned to the Commercial Crew and Cargo Processing Facility on NASA’s Kennedy Space Center.

The team now will perform propulsion system checkouts inside the factory’s hazardous processing area and determine the appropriate vehicle configuration for accessing and analyzing the system further. NASA and Boeing will recommend forward work as part of a formal process designed to aid in determining root cause and remediation steps.

In the weeks ahead, engineering teams from NASA and Boeing will work to diagnose and ultimately resolve a valve issue detected during the Aug. 3 countdown for NASA’s Boeing Orbital Flight Test-2, and resulted in the decision to postpone the launch destined for the International Space Station.

NASA, Boeing, and ULA will establish a new launch date once the issue is resolved.

NASA and Boeing have decided to postpone the launch of Orbital Flight Test-2 to the International Space Station as teams continue work on the CST-100 Starliner propulsion system.

Engineering teams have been working to restore functionality to several valves in the Starliner propulsion system from inside United Launch Alliance’s Vertical Integration Facility that did not open as designed during the launch countdown for the Aug. 3 launch attempt. The valves connect to thrusters that enable abort and in-orbit maneuvering.

“We made a lot of progress to open the valves from inside the Vertical Integration Facility, and the NASA-Boeing teams did a great job doing everything we could to get ready for this launch opportunity,” said Kathryn Lueders, associate administrator for NASA’s Human Exploration and Operations Mission Directorate. “Although we wanted to see Starliner fly in this window, it’s critical that our primary focus is the safety of the crew transportation system – for the safety of the space station and the crew members that will be flying on these vehicles. We’ll only fly this test when we think we are ready, and can complete the mission objectives.”

Inside the VIF, Boeing was able to prompt nine of 13 valves open that previously were in the closed position using commanding, mechanical, electrical and thermal techniques. Teams will now begin the process to move Starliner back to Boeing’s Commercial Crew and Cargo Processing Facility in Florida for deeper-level troubleshooting of four propulsion system valves that remain closed and more detailed analysis on the spacecraft.

“Mission success in human spaceflight depends on thousands of factors coming together at the right time,” said John Vollmer, vice president and program manager, Boeing’s Commercial Crew Program. “We’ll continue to work the issue from the Starliner factory and have decided to stand down for this launch window to make way for other national priority missions.”

NASA, Boeing and ULA will establish a new launch date once the issue is resolved.
