Bummer, it looks like the space shuttle Endeavour’s Friday afternoon launch has been called off, last minute, due to technical issues.
Shuttle Launch Director Mike Leinbach has scrubbed today’s STS-134 launch attempt because of an issue associated with Auxiliary Power Unit 1 heaters. There will be at least a 48-hour scrub turnaround while engineers assess the issue. NASA Television will air a news conference later this afternoon.
That’s all we know for now, but we’ll update as soon as NASA airs the news conference and gives us the lowdown.
I know, “boo-hiss.” Except for the part where “hooray, saving lives!”
