  1. Cernan and Schmitt covered that distance in 22 hrs on Opportunity Breaks NASA's 40-Year Roving Record · · Score: 3, Interesting

    , spread over 3 separate EVAs in 3 days. All of the unmanned US and Russian rovers took a lot longer to set their distance records.

    If the Apollo program was allowed to continue past 17, there were plans for even longer distance surface excursions. There were even preliminary studies done for a small flying vehicle to allow the astronauts to cover even longer distances from their landing site.

    They rely on the resonant frequency of atoms in metal vapors (Cesium or Rubidium), or the output of a hydrogen maser.

    Radioactive decay is a chaotic process. So chaotic that it can be used as the basis for a random number generator. Just what you DON'T want in a precise time/frequency reference.

  8. Re:Density on Graphene Aerogel Takes World's Lightest Material Crown · · Score: 2

    Just to clarify, you would need to seal the outer surface, and pull a vacuum on the internal volume of the material. Then, assuming that the sealing coating didn't weigh too much, the stuff should float.

  16. Ephedra... on Why It's So Hard To Predict How Caffeine Will Affect Your Body · · Score: 3, Informative

    Ephedra disappeared from the market because of negative press coverage of several stupid athletes who abused it.

    Personally, I think that the War on Drugs had a lot more to do with that. Ephedra (and the active alkaloid, ephedrine) can be used as precursors for methamphetamine manufacture. The FDA yanked ephedra and ephedrine products about the same time that the DEA rammed through the laws requiring you to put your name into a federal database to buy a package of cold/allergy pills.

  22. Re:It's kind of sad on A Firecracker-Launching Slingshot: Start the New Year With a Bang · · Score: 2

    If you watch the slo-mo shot of the explosion inside the gel block, you can see that the explosion blows out the ends of the paper tube, without rupturing the tube itself, which would take a LOT more pressure and make a LOT more noise.

    I suspect the the ends of these things are simply crimped shut, rather than sealed with a glued in plug like an M-80. Probably done to limit the power for safety reasons. They also apparently use black powder, rather than the more energetic flash powder used in M-80s. But 2 grams of fine grain black powder is enough to make a heck of a bang if properly contained.

  25. Yes, but smoking might fade away with legalization on Link Between Marijuana and Psychosis Goes Both Ways · · Score: 1

    Smoking or vaporizing is the most "efficient" method of ingestion, in that it gives the maximum effect (and fastest onset) from the minimum amount of marijuana. This is important for most smokers considering the price of an ounce of good grass these days.

    If the stuff were priced more in line with what it is (a dried herb), rather than an illegal black market commodity, users could afford to use it is less harmful ways. But spending a couple hundred dollars to make a batch of brownies is kind of prohibitive for a lot of people...
