China's Nuclear Rover Will Sample the Moon

HansonMB writes "After launching on one of the nation's Long March rockets and a three-day transit, Chang'E 3 will reach the Moon and enter into a 62 mile orbit. Once settled, the 2,645 pound lander will separate from the roughly 8,200 pound spacecraft and descend into a highly elliptical orbit 62 by 9.5 miles above the surface." Russia wants a taste, too, and plans a moon-sampling mission set for 2015.

      I would think this should be more obvious, but it's "cooler" for the people onboard. Do you think it would have been a whole lot cooler if the Spanish had just sent robots to the New World?

      Humans are going to colonize space, and it's not for your personal entertainment, but because people with a spirit of exploration want to see what's out there and want to set foot on and colonize new worlds. The early settlers didn't migrate to the New World for the purposes of entertaining those back home. Public Space Programs may be entertaining, but they're not primarily entertainment programs (likewise for projects like Elon Musk's).

      Of course, projects like Hubble wouldn't be any better with 'a guy in it'. But is there advantage to acquiring the know-how to have humans in space? Absolutely. If you can't see why it's "cool" to get humans to Mars, then rather just go back to playing video games or whatever entertains you, because there's not much else in this universe that is going to fire your imagination.

      That humans are going to colonize space is by now a matter of 'when and how', not 'if'.

      Why send humans when you can just send robots.

      Why send robots when you just not send anything at all? At some point, you are assuming that there's something valuable to do in space. Else just not doing anything is the correct choice.

      As it turns out both robots and humans have their place in space activities. Robots are the obvious winners for virtually all extreme exploration, such as sending something out for the first time (the unmanned probes that were part of the Apollo program and used to scout possible sites and try out landing technology), to an environment that simply is not survivable (for example, a one way trip into the atmospheres of Jupiter or Venus), or lasts a ridiculous length of time (the Voyager missions).

      Robots are also good for easily automated tasks such as imaging and communications. And as the software improves, one can expect more such tasks to be automated.

      Humans are better for missions that have a lot of complexity and on site decision making. The Apollo program contains a good example of human activity that couldn't be readily duplicated by an affordable amount of robotics on Mars. Overall human time on the Moon was something like three or four weeks of human time (including the fact that there were two people on each of the half dozen missions that made it to the Moon).

      For example, consider the scientific missions to Mars over the past forty years. Each of the last three lunar missions duplicated the basic feats of any of the rovers on Mars, but in a couple of days rather than a number of years. And a powerful component of the Apollo program was the sample return, which still generates considerable academic activity today.

      People tend to forget that a manned mission could generate as much scientific knowledge in a few weeks as the unmanned landers and rovers have over the past last forty years. And that's a good use of humanity's real strength, the Earthside infrastructure that has had to make do with a remarkably thin gruel for four decades.

      There's also the goal of eventual colonization of space. One has to use humans at some point in order to further that goal beyond a rudimentary level.

      That dovetails nicely to the comment I wanted to make. Humanity BADLY needs to stop treating the space exploration fantasy as an opportunity to run away from what we've already messed up. We need to get our shit together in the here and now, and not act like we can just sput off to somewhere else, leaving behing a messy shitpile in our wake.

      Frankly, we've got a long way to go before we are ready to rocket off some place else. It's fun to fantasize about being the first cowboy in space but eventually one has to grow to adulthood.

    This may be why the communists are making the trip - 'Between 1969 and 1972, Apollo astronauts brought just under 842 pounds of rocks and regolith back from the Moon. In 1985, engineers at the University of Wisconsin discovered significant amounts of Helium-3 in the lunar soil. Helium-3 is a stable isotope of helium — the gas we use to fill party balloons with — and is notable because it’s missing a neutron, an important property that means we can used it in nuclear fusion reactions to produce clean energy. Unfortunately, our most plentiful stores of the isotope are a quarter of a million miles away.' http://news.discovery.com/space/space-energy-mining-the-moon-120907.htm

    Could the text be in metric ? I find it annoying to go and convert x pounds of things in meters every time an article is added.

    Once settled, the 2,645 pound lander will separate from the roughly 8,200 pound spacecraft and descend into a highly elliptical orbit 62 by 9.5 miles above the surface

    2,645 GBP (4,225.29 USD)? That's bloody cheap, it used to cost millions.

    The Russians launched a series of probes in the 70s (Luna 16, Luna 20 and Luna 24) that went to the moon and brought back samples.

    Although I guess the novel thing this time is that it combines the Luna sample return missions with the Lunokhod rovers.
