DASH (without DFM motors) [ISAS]

DASH (Demonstrator of Atmospheric reentry System with Hyperbolic velocity) was intended to demonstrate the reentry of a capsule with hyperbolic speed for later application in return capsules of interplanetary probes. The capsule has the same properties as the return capsule of the MUSES C (Hayabusa) mission.

After launch, the DASH spacecraft did most probably not separate from the VEP 3 spacecraft, which served as a carrier. No contact could be established.
