EU Sending a Probe To the Sun

First time accepted submitter Mindflux0 writes "The European Union is going forward with the proposed Solar Orbiter, a space probe designed to study the sun. The probe will orbit closer to the sun than any other man-made object at a sizzling 42 million km. It's planned to launch in 2017 for close to a billion euros."

      No, no it will not be close to absolute zero. Conduction will carry the heat from the sun-facing side of the craft to the dark side of the craft -- even if they weren't deliberately using pipes to move heat to the radiator. The craft will reach an equilibrium point that is based on the amount of heat it is absorbing, the size of the radiator, and the amount of blackbody radiation given off at a given temperature of the radiator.

      At this distance from the sun, this temperature is going to be rather high.

      To get close (as in 12K) to absolute zero, it took the WISE craft a significant store of solid hydrogen to use as coolant, and this was at 1 AU from the sun.

If the factory gives you something that you feel is worth the investment, such as cheap robots that clean homes and which anyone can afford, then you didn't waste money. If that factory gives you something that you feel wasn't worth the investment, such as black and white TVs nobody has had a use for since decades, then you wasted money.

    Is learning more about the sun worth the 1 billion worth of resources and work? That's the question.
    The comment you answered to is quite ignorant though. The fact that he claims this is a waste of money then immediately says he actually has no clue what we could get out of this, gives the stupidity away.

    To answer the guy:
    For one thing, we could learn how to develop better sources of energy (or how to use current energy sources more efficiently). The sun burns thanks to a process called Fusion, which is much, much more efficient than the nuclear energy we have today (fission). We're desperately trying to develop Fusion plants to replace Fission plants and studying the sun upclose might help us this way. Imagine the shitload of money we'll save thanks to that energy source!

    We could also learn a lot more about Earth's climate and global warming. We might be able to predict future drastic changes in temperatures that are caused by solar activity. Imagine if we could know today that 10 years from now, the temperatures on Earth will drop by 5 celsius for a period of 15 years - we could start preparing for this by modifying buildings. A few years ago friends of mine considered changing the heating system in their house to something that is cheaper to run. They ended up not investing in this because, as they said "last winter wasn't so cold. If the next 10 winters are not ALL colder, we won't heat the house so much and this won't be worth the investment". If they could know how cold winter will be 10 years ahead, they would be able to make a better decision. It would save them money and it would help the climate a little bit.
    As for global warming, we might finally get an answer as to how much man is responsible for it.

    We will also most likely learn things we didn't expect to learn. That happens all the time in science, especially with big enterprises. For an example, look at how the LHC has unexpectedly allowed us to discover particles that can travel faster than light (ok, last I heard this needs further verification, but you get the example).
    Speaking of the LHC, people raised the same "Is it not a waste of money?" concerns. The LHC was presented as something that would simply satisfy our curiosity about the origins of the universe, but according to some scientists I spoke to the LHC might help us develop cheaper and more efficient energies and it might even be the only way to develop anti-gravity engines - imagine vehicles of all sized, from a skateboard to an oil tanker, not fighting against gravity (like planes and helicopters do) but simply ignoring gravity at will (picture a helium balloon, although balloons float only because they are lighter than air) and moving (or stopping) with ease in the air! It sounds like science fiction, but it's actually a real possibility (or so I've heard).

    There's so much more we could learn from studying the sun closer. A scientist would be able to provide more examples. But there are good reasons to do it and in the long run it could save us lots of money and help climate change/pollution.
