For satellites as small as a briefcase, getting around in space just got a whole lot easier
For satellites as small as a briefcase, getting around in space just got a whole lot easier Lisa Lock Scientific Editor Robert Egan Associate Editor MIT engineers are testing a new propulsion system that combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters. The system could enable the design of nimbler, more flexible small satellites, which could perform both fast, powerful maneuvers and slower, precise adjustments,...

MIT’s new spacecraft engine could send tiny satellites to Mars
MIT’s new spacecraft engine could send tiny satellites to Mars MIT’s new “best of both worlds” rocket system could give tiny satellites the power to sprint, cruise, and explore deep space using a single fuel tank. - Date: - June 10, 2026 - Source: - Massachusetts Institute of Technology - Summary: - MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do.
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing Stephanie Baum Scientific Editor Robert Egan Associate Editor For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate according to the unique and complicated rules of quantum physics.
