HOUSTON – Chris Ferguson, a former space shuttle commander who is now director of Crew and Mission Operations for Boeing Space Exploration, takes the controls inside the company's CST-100 spacecraft simulator. To Ferguson's right, an engineer observes the exercise. Boeing demonstrated that the CST-100's software allows a human pilot to take over control of the spacecraft from the computer during all phases of a mission following separation from the launch vehicle. The pilot-in-the-loop demonstration at the Houston Product Support Center is a milestone under Boeing's Commercial Crew Integrated Capability agreement with the agency and its Commercial Crew Program.

The United Launch Alliance (ULA) Atlas V first stage booster for the Crew Flight Test of Boeing’s CST-100 Starliner is in production in ULA's factory in Decatur, Alabama on March 1, 2019. Soon the booster will be assembled with the dual engine Centaur upper stage. They will be shipped aboard the company’s Mariner cargo ship to NASA’s Kennedy Space Center in Florida. Starliner and the Atlas V rockets that will launch the spacecraft, are key to restoring the nation’s capability to send astronauts to the space station from U.S. soil with NASA’s Commercial Crew Program. NASA astronauts Mike Fincke and Nicole Mann, and Boeing astronaut Chris Ferguson will launch to the space station aboard the Starliner for the Crew Flight Test.

Former NASA astronaut and test flight pilot for the first manned flight of the Boeing CST-100 Starliner spacecraft, Chris Ferguson, speaks after the capsule landed in White Sands, New Mexico, Sunday, Dec. 22, 2019. The landing completes an abbreviated Orbital Flight Test for the company that still meets several mission objectives for NASA’s Commercial Crew program. The Starliner spacecraft launched on a United Launch Alliance Atlas V rocket at 6:36 a.m. Friday, Dec. 20 from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

NASA Administrator Jim Bridenstine, NASA Deputy Administrator Jim Morhard, Kennedy Space Center Director Bob Cabana, and NASA Astronauts Josh Cassada and Suni Williams, who are assigned to Boeing’s first operation flight of Starliner, and NASA astronauts Nicole Mann, Michael Fincke, and Boeing astronaut Chris Ferguson, who are assigned to Boeing’s Crew Flight Test, are seen during a press conference ahead of the Boeing Orbital Flight Test mission, Thursday, Dec. 19, 2019, at NASA’s Kennedy Space Center in Florida. The uncrewed Orbital Flight Test will be Starliner’s maiden mission to the International Space Station for NASA's Commercial Crew Program. The mission, currently targeted for a 6:36 a.m. EST launch on Dec. 20, will serve as an end-to-end test of the system's capabilities. Photo Credit: (NASA/Joel Kowsky)

Two United Launch Alliance (ULA) Atlas V dual engine Centaur upper stages are in production in ULA's factory in Decatur, Alabama on March 1, 2019. One is for Boeing’s Crew Flight Test on the CST-100 Starliner, and the other will be used for the first crew rotation mission on the Starliner. One of the Centaur upper stages will be assembled to the first stage booster. They will be shipped aboard the company’s Mariner cargo ship to NASA’s Kennedy Space Center in Florida. Starliner and the Atlas V rockets that will launch the spacecraft, are key to restoring the nation’s capability to send astronauts to the space station from U.S. soil with NASA’s Commercial Crew Program.
