Re: [Vo]:Should We Send a Team to Rescue Curiosity?
If this does happen, it will be fortunate, and it will come at an ideal moment in history. The report says this object is 50 km in size and it would release 20 billion megatons. I say this will be fortunate because it will put the fear of God into the human race, and spur us to take the threat of asteroids seriously. It comes at an ideal moment because we have spacecraft orbiting Mars, and on Mars, so I do not think there will be any question we will see the impact, and measure the approximate size of it. There will be no doubts about it. If this had happened 50 years ago we might not have noticed. - Jed

A 10-km object striking at 20 km/s will produce roughly 600 million megatons. See: http://www.astronomynotes.com/solfluf/s5.htm This object is traveling the opposite direction of Mars, so the speed of impact would be 56 km/s. (Megatons in this context means megatons of TNT equivalent. Nuclear weapons jargon. The biggest bomb in history was 50 MT. According to this website, 6 x 10E7 MT = the force of a 9.4 Richter scale earthquake, about the same as 2011 Japanese quake.) - Jed

Jed, I am in your camp on this. It is time we figure out all that is orbiting out there, some of it at extremely high speeds and energy levels I believe.

Looking around for something besides Pravda as a reporter, I found: http://io9.com/5986954/could-a-comet-hit-mars-in-2014 It says: === It seems the likelihood of an awesome planetary impact is low — for now. According to calculations by NASA's Jet Propulsion Laboratory (JPL), close approach data suggests the comet is most likely to make a close pass of 0.0007 AU (that's approximately 63,000 miles from the Martian surface). However, there's one huge caveat. Due to uncertainties in the observations (the comet has only been observed for 74 days), it's difficult for astronomers to forecast the comet's precise location in 20 months time; comet C/2013 A1 may fly past at a very safe distance of 0.008 AU (650,000 miles). But to the other extreme, its orbital pass could put Mars directly in its path. At the time of Mars close approach (or impact), the comet will be barreling along at a breakneck speed of 35 miles per second (126,000 miles per hour). === So nobody knows for sure, but it's unlikely to hit Mars. I may not know what I am talking about, but although Jupiter was hit by Shoemaker-Levy it is closer to the asteroid belt than Earth, which seems like it would make it more likely that an asteroid would wander toward it; being 11 times the diameter of Earth makes it a bigger target, and maybe with umpteen times Earth's gravity it tends to suck in space junk more voraciously than Earth does. I am more worried about being swallowed by one of ChemE's sinkholes than by being clobbered by an asteroid.

To give credit where it is due, NASA and other organizations have made great strides locating these things since the 1990s. They are working with modest budgets and small telescopes, using clever software. Relatively small telescopes are better suited to this purpose. The first step is to find them! In one of his books, Arthur Clarke suggested deploying a bunch of sensors orbiting the sun, and then setting off a gigantic neutron bomb on the other side of the sun (away from Earth and other populated planets) to make something like an instantaneous x-ray of the solar system, to find every last object big enough to be dangerous. What I loved about Arthur was that he was never afraid to Think Big. - Jed

I guess it was a bomb tuned to make gamma rays. It made what you might call a gigantic radar picture, rather than an x-ray. I don't recall which book that was in. Radar was one of Arthur's favorite things, since that's what he did professionally. As I recall, it turned into what a programmer would call a Hello World! test. A century later an extraterrestrial civilization responds. I have heard that according to recent analyses, radio and television broadcasts cannot be detected after a few light years. So the scenario portrayed in the Carl Sagan's Contact is impossible. That's a pity. - Jed
Re: [Vo]:Should We Send a Team to Rescue Curiosity?
This is a comet, from wy out in the ort cloud If we are targeted by a comet like this we will have less than 24 mo warning. We can't find everything out that far that could hit us, we can find all of the asteroids, but not the all comets.. They come from too far away We don't need to just search, we need a redundant robust response sitting on the pad ready to go on 4 weeks notice A retograde impact with a 50Km object would be billions of megatons equivalent energy... energy is 1/2mv^2 Retrograde is 2X V and the mass is proportional to the volume squared So if a 2Km rock caused the dinosaur die off this would be (50km/2km)^3* (2*V)^2 or 62500 times MORE powerful than what killed the dinosaurs.
