A southeast Iowa native will have to wait a little longer to make his first trip into space.The launch of the space shuttle Discovery has been pushed back due to the delay in launching Atlantis two weeks ago. The Atlantis launch is now slated for February 7th. Air Force Lieutenant Colonel Jim Kelly is scheduled to be the pilot on the Discovery mission, now scheduled for liftoff March 8th. Kelly is a Burlington native who now lives in Houston, Texas. The mission will take him to the International Space Station to deliver supplies, experiments and crew and will include two spacewalks. The 36-year-old Kelly will become the fifth Iowan to go into space.Other Iowans who’ve flown aboard the shuttle are: George Nelson of Charles City, Colonel David Hilmers of Clinton and Colonel Loren Shriver of Jefferson. Back in 1968, Colonel Walter Cunningham, of Creston, flew aboard Apollo Seven.
