Officials are trying again Tuesday to launch a part-Russian, part-Korean space launcher on a historic mission that could propel South Korea into the Space Age.

The 108-foot-tall Korea Space Launch Vehicle, or KSLV 1, is set for liftoff at 0800 GMT (4 a.m. EDT), or at 5 p.m. local time at the Naro Space Center at the southern tip of the Korean peninsula.

The launch has been postponed several times over the past few weeks, first from July 30 and then from Aug. 11.

The countdown clock ticked within eight minutes of launch last Wednesday, but the control team scrubbed the mission due to flaky software that triggered an automatic hold.

Engineers conducted another countdown rehearsal Monday with no problems, setting the stage for Tuesday's launch attempt, according to the Korea Times.

The KSLV 1 rocket, also named the Naro 1, will orbit a 219-pound science and technology demonstration satellite during an eight-minute launch sequence.

The launcher is targeting an orbit with a high point of 1,500 kilometers, or 932 miles, and a low point of 300 kilometers, or 186 miles, according to the Korea Aerospace Research Institute.
