#GRAIL is "Go" for MST roll back after Phase 1 lightning warning is lifted at approx 9PM! @NASATweetup Go GRAIL!
Excited by #GRAIL? Do 3 things: 1) go to Launchwatch.org 2) Look up at the Moon differently now 3) Tell/Inspire someone!
#GRAIL A and #GRAIL B are now at the moon...we'll take about 2 months to trim the orbits and get the science measurements started.
@schierholz @NASATweetup @trentperrotto The launch management team met. TS Emily not a threat. Proceeding with the count! GO ATLAS! GO JUNO!
#GRAIL Status briefing. Red limit problem resolved. Upper level winds strategy reviewed. Wx is 60% "Go". Go GRAIL! 8:29 AM EDT @NASATweetup
#GRAIL A main engine stop...we are at the Moon!
