CNSA / CAST
CNSA/CAST ascent stage from lunar surface to lunar orbit for sample canister transfer on Chang'e-5.
The ascender is the CNSA and CAST ascent stage that lifts a sample canister from the lunar surface into lunar orbit.
Mission brief
On Chang'e-5 it carries the sample canister from the surface up to lunar orbit.
Schematic
The stage mates to the sample canister and climbs from the surface to the orbiter. This page links the Chang'e-5 ascent vehicle and the Chang'e-6 ascent vehicle. The Chang'e-6 stage lifts that mission's sample canister from the far side to its orbiter.
