In this Thursday, July 13, 2017 photo, NASA astronaut Victor Glover signals back up to astronaut Daniel Burbank that he is OK after jumping into the Gulf of Mexico from the Orion capsule the astronauts are using to practice an emergency egress situation during recovery testing about four miles off of Galveston Island, Texas. The testing is the first time since the Apollo program that NASA has practiced such egress techniques from a capsule in open water. (Mark Mulligan/Houston Chronicle via AP)
