Sounding rockets are normally used for brief, inexpensive space and microgravity experiments.

He has conducted extensive research in rocket engines and microgravity experiments.

During 14 days, 31 microgravity experiments were completed in round-the-clock operations.

Columbia touched down almost 14 days later returning with data and specimens amassed from an important suite of microgravity experiments.

Applicants were challenged to design a microgravity experiment, and submissions closed in early December.

His microgravity experiments with transparent liquids proved the importance of the Marangoni effect.

Even small actions can shake up delicate microgravity experiments taking place inside the station's laboratories.

Such disturbances, though slight, could affect the sensitive microgravity experiments.

The students asked a variety of questions about the microgravity experiments being conducted during the mission on living and working in space.

During the 73 campaigns in which he took part, he supervised a total of 858 microgravity experiments.
