NASA’s Magnetospheric Multiscale mission began with a brilliant liftoff from Cape Canaveral Air Force Base in Florida aboard a United Launch Alliance Atlas V rocket. Launch was right on time at the first opportunity at 10:44 p.m. EDT and came on the heels of a smooth countdown.
“The countdown today went very well,” NASA Launch Manager Omar Baez said. “We really worked absolutely no launch vehicle or spacecraft issues, the range was green and the flight was nominal. Picture perfect.”
“This evening unfolded essentially perfectly for us,” MMS Project Manager Craig Tooley said of the countdown and flight. He reported all four spacecraft appear healthy following separation.
“It appears all four are where they need to be,” Baez said. “You can’t ask for anything more.”
With that we’ll conclude live launch coverage. Thank you for joining us! For the latest news on the MMS mission, visit https://www.nasa.gov/mms.
