STS-134 launch has been shifted again to a new “no earlier than” date: May 16th at 8:56 a.m. EDT. The window will be open till May 20th; then in order to avoid overlaps with undocking Russian Soyuz TMA-20, another launch opportunity will follow from May 22 to May 26.
At JSC, STS-134 crew is ready to come back at KSC, where engineers and technicians are working hard to solve all issues at the orbiter’s Auxiliary Power Unit that caused the scrub. In the meanwhile both at Cape Canaveral (KSC) and Houston (JSC), AMS-02 team is getting ready for launch and post-launch activities. Now the experiment is switched off and safely still in the Endeavour bay. If launched on May 16th, it will be installed on the ISS on May 19th.
