Photos: Gantry rolled back to reveal Orion

A Canadian space flier will join three NASA crew members on the first piloted flight of the Space Launch System and Orion spacecraft around the moon, becoming the first non-U.S. astronaut on a lunar voyage, officials announced last week.

President Donald Trump signed a new NASA authorization bill Tuesday, the first such space policy framework since early in the Obama administration, that largely continues the space agency’s efforts to foster a commercial economy in Earth orbit and explore deep space, with an eventual goal of landing humans on Mars.

A countdown dress rehearsal and rocket fueling exercise was completed at Cape Canaveral for next month’s launch of NASA’s Orion crew module atop a United Launch Alliance Delta 4-Heavy booster.
