NASA astronaut Eric Boe recently toured Boeing’s spacecraft testing facilities in Huntington Beach and El Segundo, Calif., along with fellow commercial crew astronauts Nicole Mann and Chris Ferguson. All three will fly on Boeing’s CST-100 Starliner in an upcoming Crew Flight Test to the International Space Station. Structural testing in Huntington Beach confirms the spacecraft can withstand the pressures it will experience during flight. Environmental qualification testing in El Segundo ensures the spacecraft can withstand the extreme environments of space.
