Rosetta's Philae Probe To Land On Comet Tomorrow

An anonymous reader writes: After more than 10 years travelling, the Rosetta mission will take its next, momentous step by landing the Philae probe on comet 67P/Churyumov-Gerasimenko tomorrow. How f!@#$%ing cool is that?! Follow the landing live using the webcast, blog, or Twitter feed. (Keep in mind there's a 28-minute delay due to the time it takes the radio signals to reach Earth). Here's the scheduling info: "For the primary landing scenario, targeting Site J, Rosetta will release Philae at 08:35 GMT/09:35 CET at a distance of 22.5 km from the center of the comet, landing about seven hours later. The one-way signal travel time between Rosetta and Earth on 12 November is 28 minutes 20 seconds, meaning that confirmation of the landing will arrive at Earth ground stations at around 16:00 GMT/17:00 CET. If a decision is made to use the backup Site C, separation will occur at 13:04 GMT/14:04 CET, 12.5 km from the center of the comet. Landing will occur about four hours later, with confirmation on Earth at around 17:30 GMT/18:30 CET. The timings are subject to uncertainties of several minutes."

      Actually the speed of light is just about perfect for the photon. At the speed of light, time dilation/spatial contraction allows it to be pretty much everywhere on its world line at the same "time". Thus space is certainly not too big for the photon (if you ignore inflation).

His solution to this is to sends a probe to an easier target, the sun. His scientists commended him on his clever thinking since the gravity well of the sun would help overcome some of the deficiencies in North Korea's rockets. But they were forced to also inform him that although the goal of sending a probe to the sun was doable, they would not be able to match the feats of other nations by actually landing the probe on the sun due to the intense heat. The "Dear Leader" replied he had though of that and told them to simply land at night.
