After-Mission Europa Return
on: September 24, 2013, 14:54

Hello, I am preparing to write a report on a two vehicles I am proposing.
One is the Europa Ascent Rocket (EAR), that will lift the astronauts into Europa orbit, where they will rendezvous and dock with the Europa Transfer Stage (ETS) for their return to Earth.

The EAR is landed around a year prior to the arrival of the astronauts. Upon landing, the EAR will test and see if the ice is thick enough for the astronauts, and provide a crucial information ground on the nearby environment. It will then deploy a small rover to explore the nearby area and deploy radio beacons to guide the astronauts.

The astronauts will be launched with another EAR, which will follow them, and land with them if they happen to land off-course.

After the launch of the EAR, an ETS ship will be assembled in orbit and sent on its way to Europa. The ETS is entirely optional (I am assuming there is no spacecraft to take them here and back), and is powered by Plasma.

Once the astronauts have completed their surface stay, the board the EAR, launch toward the ETS, rendezvous and dock, before the ETS returns to Earth.

I'm currently doing some concept designs for the EAR and ETS, and will post them shortly.
I'm considering the implementation and replacing the ETS with the Europan Transfer Vehicle, an modified and larger ETS that will bring us there and back, and is refueled at LEO for the next mission

I'm currently working on an entire mission profile right now. Concept art and specifications will be added soon

Please go through steps 1-5 as seen on http://www.objective-europa.com/research-topics/

We are looking forward to your contribution!!

Yes, but I cannot email you my data and expected outcome because, after all, I'm still learning.

I'm making changes to my plan as I learn new things and new factors, and am still unsure of the main mission architecture of return.

Hello, The mission basis sounds interesting but the powersource is kind of unstable with todays technology, wouldnt it be better to build some type of metamaterial to demodulate radiation to something usefull like concentrated light or electricity, that way you could protect the crew from jupiters intense radiation rings and use the radiation to power the vehicle.

Just a tought.

Good idea. I am looking into ways to convert the radiation of Jupiter into electricity.
But it does not have to be Plasma. I'm also considering Nuclear fusion, electric engines (Ion thrusters and such), and as much as the environmentalists will hate me, possibly even nuclear pulse propulsion.

As of now, only electric propulsion, VASMIR engines, and nuclear pulse propulsion could be used, but I'm placing my bets on the fact that nuclear fusion COULD eventually turn up as a propulsion method around 2040, around time for a manned Jovian mission.

While plasma and VASMIR engines may not be feasible today, it could be feasible around the time where we start exploring the Jovian and Saturnian system.

I was curious to know if you have any updated info on this, or new findings.

Hi, I have noticed that there are questions about radiation and shielding materials and some rather heavy and difficult to apply materials are suggested.
Perhaps taking advantage of the work already done by Bigelow Aerospace may be part of the answer.
