Surviving EX

IMSS Programme was the first cancelled flight from designation; and Phantom X Project was the last cancelled flight for Dragon X.

On 9 May 2008, the failure launch of the third International Malaysia Space System (IMSS) forced Dragon X to close up IMSS designation. Followed up by the Shadow Project, Hypersonic X-386, Diamond Ring Project and the last, Phantom X Project.

Shadow Project, Diamond Ring Project and Phantom X Project were cancelled due to the failure of the Ignition Burn Pod (IBP). While Hypersonic X-386 was cancelled due to an accident during attachment onto Ocean 2 on 31 July 2008.

EX Programme was the only one Dragon X's longest operating programme since 2008. EX Programme is the only one surviving designation until today, which the designation is still in the development of Dragon X.

The other designation is Aquarius, which will launch for the final mission on 20 December 2011. Aquarius will launch on the close up mission for the entire Water Rocket Programme, and was also known as the M-41e mission.
