When the NASA shuttle Atlantis takes off Friday, it will be the 135th and final mission in the space shuttle program that began 30 years ago.
Almost a million people are expected to attend the historic shuttle launch that is scheduled to take off at 11:26 a.m. ET barring possible thunderstorms that could hit the area.
The final mission will take four astronauts into space for 12 twelve days for them to deliver supplies to the international Space Station.
“I don’t think we’ll see another vehicle like it, for decades perhaps,” Atlantis commander Chris Ferguson told CNN. “I mean, just the technology involved in flying back from space. It’s an amazing vehicle, and its legacy will live on.”
