Boeing’s Starliner spacecraft landed in New Mexico, wrapping up a three-month test mission that faced technical issues and forced it to leave the two astronauts it carried temporarily stranded in space.The spacecraft touched down at White Sands Space Harbor in the New Mexico desert on September 7. The two crew members it had flown to space – Butch Wilmore and Suni Williams – remained at the International Space Station (ISS) due to safety concerns with the craft.
