When it comes to generational milestones, those of born since the late 70’s often feel like we’re lagging behind previous generations. Unlike the “Greatest Generation” or the “Baby Boomers”, we weren’t around to witness Two World Wars, the Great Depression, the Cuban Missile Crisis, the death of JFK, Neil Armstrong, or the FLQ Crisis. For us, the highlights were things like the development of the PC, the birth of the internet, Kurt Cobain, and of course, 9/11.
But looking ahead, those us of belonging to Generation X, Y, and Millennials might just be around to witness the greatest event in human history to date – a manned mission to Mars! And while NASA is busy planning a mission for 2030, a number of private sources are looking to make a mission happen sooner. One such group is a team of UK scientists working from Imperial College London that are working to mount a a three person mission to Mars.
The planned mission consists of two spacecraft, the first of which is a Martian lander equipped with a heat shield that will send the crew off into Earth’s orbit. The second craft would be a habitat vehicle, which is the craft that the crew would live in during the voyage. The habitat vehicle would consist of three floors, and measure in at around 30 feet (10m) tall and 13 feet (4m) in diameter.
The astronauts would be situated in the lander during takeoff, and would move to the habitat when the dual-craft reaches Earth orbit. Once the astronauts are safely within the habitat, a rocket would shoot the dual-craft off on its journey to Mars, which would take nine months to arrive, less than the approximately 300 days that most projections say it will take.
Once In space, the dual-craft would then split apart but remain connected by a 60 meter (200 foot) tether. Thrusters from both vehicles would then spin them around a central point, creating artificial gravity similar to Earth’s in the habitat. Not only would this help the astronauts feel at home for the better part of a lonely year, but it would also reduce the bone and muscle atrophy that are associated with weightlessness.
The craft would be well-stocked with medicine to ensure that the crew remained in fine health for the nine month transit. Superconducting magnets, as well as water flowing through the shell of the craft, would be employed to help reduce both cosmic and solar radiation. And once the dual-craft reaches Mars, it would tether back together, the crew would move back into the lander, and then detach from the habitat descend to the Martian surface.
This mission would also involve sending a habitat and return vehicle to Mars before the astronauts arrived, so the crew would have shelter upon landing as well as a way to get home. The crew would spend anywhere from two months to two years on Mars, depending on the goals of the mission and the distance between Mars and Earth. On the way back home, the mission would dock with the ISS, then take a craft back to Earth from there.
What’s especially interesting about this proposed mission is that each stage of it has been proven to work in an individual capacity. What’s more, the concept of using water as a form radiation shielding is far more attractive than Inspiration Mars’, which calls for using the astronauts own fecal matter!
Unfortunately, no real timetable or price tags have been proposed for this mission yet. However, considering that every individual step of the mission has been proven to work on its own, the proposed overall journey could work. In the meantime, all us post-Baby Boomers can do is wait and hope we live to see it! I for one am going sick of hearing Boomers talk about where they were when Apollo 11 happened and having nothing comparable to say!
