Weather postponed a 90,000-foot skydiving attempt for the second consecutive day Tuesday, the second test jump in a series of three expected to culminate in a new world record for Austrian Felix Baumgartner. The test jump has been rescheduled for Wednesday.

Baumgartner is trying to become the first human to break the sound barrier during freefall—the record-setting, 120,000-foot attempt is expected to happen sometime in August. In March, he successfully jumped from 71,615 feet, going nearly 365 miles per hour. His 120,000-foot attempt will break American Joseph Kittinger's 102,800-foot record, set in 1960 while doing research for the Air Force. During that jump, Baumgartner is expected to reach nearly 700 mph.

Baumgartner's project, dubbed Red Bull Stratos, will test a new, full-body pressurized suit that could allow astronauts to re-enter the atmosphere without a spacecraft in case of emergency. Officials with the energy drink company Red Bull, a major sponsor of "extreme" athletic events, said that with clear weather, the 90,000-foot jump would take place Wednesday in Roswell, N.M.
