“GIFT” is a new system that teaches vision-language generative AI models to produce accurate, computer-aided design (CAD) programs that can be used to simulate and test 3D objects. The method is more accurate than competing techniques, using a fraction of the computation.

A new propulsion system combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters. The system could enable small satellites capable of both fast, powerful maneuvers and slower, precise adjustments.
