Space Junk May Require ISS Maneuver In Advance of SpaceX's Dragon

SpaceX's Dragon capsule, loaded with food and scientific gear, is scheduled to launch toward the ISS tomorrow evening (with backup launch slots on each of the following two days). There's a last-minute wrinkle, though: Space.com managing editor Tariq Malik reports that a piece of space debris "will pass near enough to the space station on Monday morning (Oct. 8) to require an avoidance maneuver as a safety precaution, NASA space station program manager Mike Suffredini said in a briefing [Saturday]." Tomorrow's planned flight is to be the first under a $1.6 billion contract with NASA that calls for a dozen resupply flights by SpaceX, essential in the post-shuttle era."

    I was under the impression that maneuvers like this happen every few months or so, so this really isn't a big deal at all. In fact, TFA says so:

    NASA and its space station partners regularly move the space station when a piece of debris is expected to pass inside a preset safety perimeter. That safety zone is shaped like a pizza box and extends out 15 miles (25 kilometers) to either side, as well as a half-mile (0.75 km) above and below the station.

      What makes it somewhat of a big deal is that this is occurring so close to a resupply launch, especially because this is the first official commercial resupply launch (although, as you and the fancy article point out, it isn't really a big deal).

      My guess would be the limitations of radar. It is fairly easy to peg the orbital altitude from ground radar. However, it takes several readings to get the entire orbital ephemeris, especially if the object is small. As the parent post said, an object in orbit is travelling at much greater speeds horizontally than vertically, so the margin for error is greater horizontally rather than vertically.

      The ISS orbits just 400 km above the ground, and experiences enough atmospheric drag to require periodic boosts back into higher orbit. About the only debris of concern is moving horizontally when it reaches the altitude of the ISS, anything that goes past it to lower altitudes hits atmosphere and quickly gets removed from orbit.

      The Apple II+ was more expensive than other PCs at the time. It was the first computer i bought.

      But price competitiveness is a difficult thing to compare as we are not comparing apples to apples (pun intended). So if the product is not the same how can you say the price is wrong? This might be true for comparing a PC today to another PC but even those offer different features, perhaps soft features like resale value, support, reliability etc. Given that most Apple computers were good value and definitely not 2x - 4x what another company would charge for the same thing. It may 2 x what another company would charge by leaving out those soft factors or not having to pay the same % of R&D by simplying copying Apple's work. Given that Apple could not "magic" up a product without R&D, i don't see how you come up with those numbers. Instead i will just assume it is a rant, especially given it is in an article nothing to do with Apple.

    I don't agree with the troll, and points 1 and 3 are correct, but #2 is both misleading and most of it barely qualifies as science.

    Social sciences are by their very nature extremely inaccurate and extremely prone to study biases.

    Hard science is still majority published by men. There isn't a real reason for this beyond cultural, and actual real gender differences. Women generally end up having more interest outside of STEM and most women, at least in most first world countries, finding the Sciences rather boring.

    Women tend to be much more social creatures that like to be involved in many things at once, while men tend to be more single-minded, which lends itself to modern science extremely well as extreme specialization is often a requirement to get anything significant done. People do tend to gravitate towards things that are an easy fit for them sooo...

    Of course there are exceptions to every rule and your Nobel prize list is ample evidence of that. However I think we can expect the real sciences(excluding perhaps medical science) to be male-dominated for the foreseeable future.
