In the span of six years, Elon Musk’s Starlink internet constellation has shattered the near-total dominance of large satellites in geosynchronous equatorial orbit, or GEO, as the means for delivering internet services from space. SpaceX’s Starlink subsidiary now has roughly 7,000 satellites in low-Earth orbit, and last year, it reportedly surpassed 4 million subscribers around the globe. Starlink’s success has sparked interest in LEO beyond internet services.

NASA and DARPA think nuclear thermal propulsion could be the best way to get humans to Mars. Elon Musk is keeping his faith in the brute force of burning hydrocarbons. Who is right? It turns out either could work, but there are a lot of “ifs” for both strategies. Jon Kelvey has the analysis. Elon Musk told an audience in 2016 that his vision of getting a million colonists to Mars could be achieved by sending 100 people at a time on six-month journeys aboard his massive Starship spacecraft.
