NASA Prepares to Launch Comet-Buster

Chessphoon writes "NASA's Deep Impact, a spacecraft named after the 1998 movie, is scheduled to launch on January 12. If all goes as planned, the spacecraft will collide with Comet Tempel 1 six months later on July 4, and create a crater so that the inside of the comet can be analyzed."

It saves them money actually and because they have never seen the comet up close its possible that its something besides just a big rock.

      Exploration and investment are the reasons for a mission like this.

      The former -- exploration -- is what NASA and scientists will advertise in front. Why? Because we know so little about comets. Imagine, if the judgement day comes and we have to "shoot down" one of these in order to save the humanity, wouldn't you be rather comfortable to know what and how comets are really made of? We really do not know what happens to a comet when we toss a stick of dynamite into it, as its structural integrity is not well known.

      The latter -- investment -- is the second and the foremost important reason. In order for a super-power nation to sustain its technological supremacy in this world, its government must invest its money for the advancement of engineering and science [*]. The investment to a NASA's mission like this may not seem as important as an investment toward curing cancer, etc., but such assessment is near-sighted. For example, building of a scientific instrument requires a miniaturization of electronic component (in order to reduce its size and weight). Each component is also certified to withstand harsh cosmic environment (sudden changes in temperature and severe bombardment by cosmic radiation). The skills learned through these R&D may eventually trickle down to the industry, and hence possibly leading to development of affordable high-tech components (e.g., IC chips in a decade ago). Basically the high cost of R&D may be paid by the government and the industry would benefit from such learned knowledge. It is not too surprising that a medical breakthrough on cancer may come from the spread of affordable technology obtained through space research.

      [*] There was no time in history that a single nation had dominated the world without its technological advantage.

Maybe they don't weigh much, but if things in space were truly weightless, they wouldn't be in orbit. If he said things are not massless, that would've been meaningless to his point about drifting. If something is truly weightless, it would mean it experiences absolutely 0 gravitational force. It may feel weightless, and it is about as weightless as it gets, but it is not truly weightless.

      I think I understand your point, and I would agree that gravity is still acting on something in orbit. However, the centripedal force (from orbiting) is equal to the force of gravity, so that the net force is zero. Remember, weight is a force measurement (e.g. pounds of force or Newtons). Mass is measured in pounds of mass or kilograms.

      It's good you mentioned reference frame, because that is very important. In the reference frame of the orbit in space, placing a baseball on a scale (also in orbit) would read as no weight. However it would also still hurt if it hit you, because the mass is the same.

Do you ACTUALLY think that the "government" is building and running these programs? Those government workers are actually getting the bloated paychecks? It's BIG BUSINESS! And, the last time I checked, the two largest government run agencies or programs made a profit last year - the good ole' U.S. Post Office (THEY want to privatize it, darn, if it could only lose money for a while) and Social Security, which never missed a payment, has enough money to maintain solvency to 2052 (and then would still be able to meet obligations up to 80% of it's current payments) and has been the most successful GOVERNMENT program in history (ask all the presidents from LBJ to Baby Bush who have "borrowed" and left IOUs and continued to borrow from the system). Yeah, yeah, yeah, I know the argument is that it is a part of the general fund, therefore the money can be use for any purpose. But tell me this, how can we use the money for the General Fund when it's there, yet not help out the program FROM the general Fund when it needs it? Why does it then have to stand alone as a self-funding program?) To continue, both these programs are genuinely for the greater good of society. And both are being targeted for privatization. Along with all the overgrown, hazardous trees that are causing all the fire hazards in our National Parks. Yes, BIG BUSINESS would run it better. And before you go point to the example of the Millau bridge in France being built with "private" funds and for only an estimated 394m euros ($524 U.S.), instead of the billions that that the erstwhile Bay Bridge is costing in San Francisco. Remember your fables: "The devil WILL get is due!" The company(s) that built the bridge have a contract for 75 years to collect fees. How many times will this private corporation raise fees? What happens when it can't meet its obligation to repair the bridge, because their calculated fees aren't high enough or the public balks at paying them? Will the "government" then simply close the bridge? No, they will come in and "bail" out this private "BIG BUSINESS" to keep the bridge safe and operating. Instead of letting this private sector enterprise simply fail. Just ask the "private, BIG BUSINESS" airlines in the U.S.

    Sorry for the rant, but of course business is a part of the success of the U.S. and the world, not the end-all and be-all. It has always been thought of as a partnership. That is why the founders of this "democracy" put such constraints on commerce; they saw the dangers as well as the reward. Unfortunately, BIG BUSINESS as risen to such heights, that more than likely, it will choke on it's own greed and take the rest of us with it.
