News From Space: Manned Europa Mission!

europa-landerWith so much attention focused on Mars in recent years, the other planets of the Solar System have a hard time getting noticed. But lately, Europa has found itself the subject of some interest. In addition to NASA proposing to send a lander there in the near future, a private space organization is thinking of mounting a manned mission to the Jovian moon in search of knowledge and extra-terrestrial life.

This organization is known as Objective Europa, a group made up of  volunteer scientists, conceptual artists, and social-media experts. At the moment, they exist only on the internet. But with time and financial backing, they hope to form a volunteer corps of settlers that would make a one-way trip to Europa and settle the planet while they researched it.

europa-lander-2Inspired by the recent missions to Mars, Objective Europa also believes a mission to this moon would be worthwhile since it is a far better candidate for extra-terrestrial life. Mars, though it is thought to have once hosted life, is a barren and dry world in its present state. Though many are holding out for the discovery of organic particles in the near future, the likelihood of finding any complex organisms larger than a microbe remains extremely low.

Not surprisingly, their group has attracted some big-name celebrities. This includes Kristian von Bengtson, a Danish architect and co-founder of Copenhagen Suborbitals, a nonprofit focused on launching humans into space. Then there’s Michele Faragalli, a rover mobility specialist for a NASA private contractor. Scientist and diver Pierre-Yves Cousteau, son of legendary explorer Jacques Cousteau, is also on the team as an ambassador for the group.

Towards this end, they have opened up a variety of research topics for discussion on their website. These include investigating the feasibility of a manned mission versus a robotic mission, launch vehicle studies, and cost analysis.Future phases would involve raising funds, and prototyping and testing technology.

What’s more, while they have not yet stated outright how they plan to fund the mission, it seems likely at this point that crowdfunding and sponsorship will come into play. As the goal statement reads on their site:

“Our purpose is to establish the foundation for and carry out a crewed mission to Jovian ice moon Europa through international crowd-research and participation.”

mars-one-brian-versteegIf this is beginning to sound a little bit like Mars One – a similar space organization looking to send volunteers to Mars – then chances are you’ve been paying attention! In terms of their purpose, objectives, and the fact that the trips they are planning would be a one-way, the two organizations are very similar. But even more interesting is what these and other space organizations like them represent.

In an age when private space travel and exploration are beginning in earnest, crowdfunded, volunteer groups are emerging with the common goal of making things happen ahead of anyone else’s schedule. Whereas space was once the exclusive province of government-sanctioned and funded agencies, now the public is stepping in to assume a measure of control.

And thanks to new media and communications, the money, talent, and energy needed are all available. It’s just a matter of bringing them all together!

News from Mars: Another (Planned) Mission!

mars-mission1When 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.

mission-to-marsThe 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.

Mars_landerOnce 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.

Mars-mission-2This 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!
