During the first phase of the flight, the booster will separate from the capsule, after which the capsule will travel through a zero-g parabola, before re-entering the earth's atmosphere.

Membership will make it much easier for British scientists to propose experiments and to get access to facilities like a zero-G plane, which generates short periods of weightlessness by flying a series of parabolas in the sky.
