Managers delay STS-134 ET/SRB mate ahead of tank allocation options
With STS-135 heading into mission planning for a June 28, 2011 flight – pending the required funding being passed by lawmakers – managers have opted to delay the mating of STS-134’s External Tank (ET) and Solid Rocket Boosters (SRBs) to December, in order to allow a potential tank swap between ET-138 and ET-122. Meanwhile, a…
