Kaituozhe-1

The Kaituozhe rocket family is a series of launch vehicles build by the China Aerospace Science and Technology Corporation (CASC). In English Kaituozhe means Explorer.

Kaituozhe-1 or (KT-1) was small, solid fueled launch vehicle. The vehicle has performed two flights, the first in September 2002 and the second exactly one year later. The first flight failed to place a 50 kg satellite into polar orbit due to a second stage malfunction. The second flight was also a failure, however Chinese officials declared some success citing the guidance systems, fairing separation and satellite-launcher separation as successful. The Kaituozhe-1 launcher appears to have been cancelled after two unsuccessful launches. A third and fourth launch have been rumored, but are not confirmed.

Like its predecessor the Kaituozhe-2 (KT-2) is a solid-fueled launch vehicle which could be based on the DF-31 missile. Two versions were proposed:

The Kaituozhe-2 features a possibly DF-31 based stage 1, topped by a smalled diameter stage 2 and 3. It has reportedly a payload of 800 kg to low earth orbit.

The maiden flight of the Kaituozhe-2 took place at 23:45 UTC on March 3, 2017 from Jiuquan.

The Kaituozhe-2A features a possibly DF-31 based stage 1, augmented by two DF-21 based strap-on boosters. It features a stage 2 with the same diameter as the stage 1 and the same smaller diameter stage 3 as the Kaituozhe-2. It has reportedly a payload of 2000 kg to low earth orbit.
