Quote from Bryan on September 20, 2013, 22:15
The best answer I see to "Why go to Europa?" is that we are humans and exploring and expanding is what we do. In many ways, it's in our DNA.

The better question is why not to go, because those questions can lead to solutions.

Here a few reasons not to go, and by addressing these concerns and finding the answers we will be better prepared.

1. To not disturb indigenous life.

2. It would cost to much money and we should spend it elsewhere.

3. It is unethical to have a one-way mission.

4. The technology is not feasible to send humans in the near future.

5. Robots can do it better.

If you want to defend this project to your peers, be ready to counter these claims.

And perhaps we could land on Callisto and control the Europa probe from there. It looks like Callisto is way more human friendly radiation-wise and easier to escape from than Europa. That way we wouldn't disturb indigenous life, it wouldn't be a one-way mission, and the robots would not have to wait for hours to get orders or feedback from humans.

NASA already did some research for that back in 2003, and it looks like it's feasible (well, feasible given the scope of OE).

Basically, the above sources support what you say - it would be safer and more effective to land humans on Callisto and pilot robots on Europa from there.

Why wouldn't solar work? There's as much light to be gathered on europa as on earth and couldn't solar panels be potentially more efficient at cooler temperatures?

The sunlight is only app 1/25 of Earth sunlight.

Isn't the orbital period of europa also a problem?

I personally support a manned mission. I believe that given our technological capabilities, and the rate of advancement, such a mission would likely be feasible in the 2030's, but will likely be delayed due to the minuscule budget of the space agencies around the world.

However, if we do land, we must take every precaution to prevent any harmful organisms from reaching Earth, and prevent any harmful Earthlife reaching Europa.

I assume precautions such as the ones which were taken after the first astronauts landed on the moon (quarantine until they're deemed non-harmful) would be taken in this scenario, especially with the very real possibility that there may be microbes on Europa.

Hi everyone, this is my first post 🙂

I agree with VB in the sense that as a global plan we have to consider manned trip, however after some debate we can concentrate on precursor missions, but that's part of the discussion.

It will not be the first mission in the neigbourhood so we can benefit from previous ones (mission analysis). Also I think I would not worry about the relay system, by the time this is launch it shall be another relay spacecraft around from other space agencies. ie. nasa, china, etc. That means we can concentrate on just one spacecraft.

Then personally and subjectively I would concentrate on a lander, I think a lander is reasonable vs a rover. Russians sent many landers to Venus, they didn't dare to create rovers, that was common sense. The lander could be have a few instruments but nothing to do with deep drilling, forget about it. Let's face one possible option: there is no life under the ice then we go there just to see the surface!, like in Mars, isn't that enough?

I disagree with the people that talks about respecting foreign life. I'm not saying we have to go there and kill everything, but if there is contamination we have to assume it. This is going to happen sooner or later. Who does not like this shall leave the space exploration theme now, sorry to say.

Cheers

Go raiky I do agree that over working to stop contamination is going to be pointless and senseless killing is just senseless.

Someone Said assuming going there is the easy part, which is not the case at all. Human Life is quite possible there at Europa.
There would be huge difference in Temperatures at surface and under the Ice. Water is there, Oxygen is there. Radiation can be converted into Energy. That energy can be used in growing vegetables and producing Heat. Surface can be used to generate Electricity, and Life can Evolve under the Ice House. Many things are Possible. However, Forget about any alien life there, there is no such possibility.
