The .3c estimate was a best theoretical case, not proposed for Earth to Mars voyage. Note 3 days to Mars is ~50M miles/day ~2M miles / hour ~500 miles/sec or .3

The .3c estimate was a best theoretical case, not proposed for Earth to Mars voyage. Note 3 days to Mars is ~50M miles/day ~2M miles / hour ~500 miles/sec or .3%c - 1/100 of his best case estimate.
- vannevar 11y agoGood point. Cuts the acceleration/deceleration down to about 1 G, which would actually be useful.
- kpil 11y agoExactly how do the deceleration work... ? Hoping someone put a really big haystack on mars?
- vannevar 11y agoI assume they can change the angle so the thrust vector is negative. It depends on the geometry between Earth, Mars, and the spacecraft. Or maybe they accelerate to just match the orbital velocity of Mars as they arrive.
