You’ll have a chance to watch a little bit of history if you can be around a television at 3:47 Friday afternoon.

That’s when the space shuttle Endeavour is set to launch on its 25th and last mission.

NASA — the National Aeronautics and Space Administration — said Wednesday that the shuttle is ready for its 14-day mission to the international space station.

The purpose of the trip is to bring spare parts to the space station, including parts for Dextre, the robot in space. There will also be four spacewalks on the mission.

President Barack Obama plans to be in Florida for Endeavour’s launch, which will be the 134th time a shuttle has gone into space.

Weather in Florida, which is often a factor in the launch of shuttles, looks as if it will cooperate Friday. There’s an 80 percent chance that the weather will be good enough for takeoff.

Atlantis will be the last shuttle to fly. Its final mission is scheduled for June.
