Comment on What is a reasonable estimate for exploration of Jupiter’s moons? by Robert K

The only thing I would add is that the gravity well in the neighborhood of the Gallilean satellites is quite deep. Consider Io; it is almost as far from the center of Jupiter as the Moon is from the center of Earth. (there’s a small difference, but very small). But while the Moon takes 29 days to make an orbit about the Earth, Io does the same circuit in about 36 hours.
If I’m calculating right, then any maneuver (for instance, leaving the neighborhood) would take 20 times as much speed as it would in the neighborhood of the Moon.

This is bound to make manned exploration quite a bit more expensive than we’d hope.

Well, honestly, I don’t think we have the means as yet to pull off a trip to Jupiter’s moons. (Or Mars, for that matter…) However, I believe the Jupiter system would be even more dangerous & hard to explore, due to the proximity of Jupiter itself, and the intense radiation it emits. (I’m assuming manned travel.) But I know that we’re most interested in Europa, because it may have a liquid ocean under the surface ice, and Io, as it is so active. The problem with both is they trail through Jupiter’s massive radiation belts.

I really doubt it, the moons on Jupiter are mainly inhospitable, there is not only radiation from the sun, but from jupiter itself, there are many changes in the magnetic field that can disrupt electronics, the temperature makes human exploration impossible, let alone colonization.

I think the best bets are on Titan, Saturn’s moon, it has a cold temperature all right (i think -50 C or something) but the pressure is almost equal to that of earth, so any tear/oxygen leak can be easily repaired. The gravity there is so low that you can flap artificial wings and fly off the ground, so launches would be cheap and finally the planet’s full of organic compounds like methane, like the earth was way before life.

Another bet, less feasible would be making air cities (like bespin (!)) on venus, a segment of the atmosphere resembles earth, balancing weights on the bottom with light gasses on the top can keep a city ‘afloat’, and again, if any air leak, the pressure is almost equal to earth, so there is no threat. The only problem is loss of weights -> go to space, if loss of the light gases -> down to the surface, both of which result in certain death.

Mars is OK, but its way too dry, until they find some water source (ice, underground lakes or something).

The technology now is mediocre, give it a decade or two for it to be more safer.

NASA was considering a probe called the Jovian Icy Moons Explorer, but it has been cancelled for lack of funding. A probe to just Europa is still possible, but with 63 known moons, a probe to just one seems a bit limited. Clearly the technology for robotic exploration exists now. Sending people there for a round trip is probably not until to 2060s at the most optomistic, since a landing on Mars must be done, and I suspect a manned expedition to Mercury before Jupiter.

In Europe a Jupiter’s moon the Scientists speculate that the water there, so the interest

We have the ability to do it now, the manpower is what is holding us back. It would have to be a decades long thing, and no one has stepped up to the plate on that one yet.

I bought a DVR system from somewhere else that came with bullet style daytime color/black&white night vision cameras. But the camera angel was not wide enough for the area I wanted coverage on. This camera was my answer. It covered the entire front yard from a high point on a single story home. The video footage is on par or slightly less that that of a standard video camera. Plus the viewing quality was much better that the cameras the DVR system came with (again I did not buy the DVR System at Amazon). Which to me is perfect for the average single story budget strapped homeowner. I like how the housing covers the wiring to prevent someone tampering with it. It is much less noticeable than the bullet style. You can even paint the housing to match your house color. Overall I was happy with the camera's performance & price that I bought another one.

You might need extra cables or adapters depending on your setup & use. I ended up needing a male BNC to Female Video RCA adapter to work with my set up. Have fun!

I haven't had a chance to view it's night vision ability but I'm sure it's will be fine. I will update once I find out.

I bought these cameras as a replacement for a set of cameras that came with my old security system. After installation of the new cameras, I was very pleased with the picture sharpness and the color.Mounting bracket allows angle adjustment.

I bought this camera to watch who is coming to my front door. It's virtually no set up, just plug it into your TV and go! You can also connect it to your computer if you have a DVR card.

This camera sees clearly the whole front yard, plus accross the street.Way better then I thought it would be. I can see clear who is outside, in my front door, even at night. The camera has IR lights to see at night, in black and white. This camera is inexpensive, but works great. It deserves the best rating. I could not have been happier.
