Dazzling visions of humanity‘s expansion into the solar system depend first on overcoming the barrier of distance from Earth to Mars. This gulf fluctuates dramatically based on orbital mechanics – spanning from 60 million km at closest approach to 400 million km at maximum separation. Roundtrip voyage duration ranges anywhere from 9 months to over 4 years as a result using conventional chemical propulsion.
As agencies prepare for crewed interplanetary travel, priority #1 is developing advanced technologies to radically reduce transit times for astronaut safety and mission sustainability. Nuclear thermal propulsion seems our most feasible option currently to slash one-way transits down to as little as 45 days.
Join me on an exciting tour of humanity‘s quest to access Mars, revealing key figures, trade-offs and innovations set to transform the voyage in the coming decade!
