Karl Grossman is continuing his ignorant jeremiad against nuclear power in space, including RTGs:
Last month, Japan launched what it called its “space yacht” which is now heading to Venus propelled by solar sails utilizing ionized particles emitted by the Sun.
When he writes stuff like this (light sails are propelled by photons, not “ionized particles”), why should we take anything else he writes (like all of the people who died of radiation poisoning from the SNAP 9A entry) seriously? He’s just a journalism professor.
I have to admit, though, it’s kind of amusing that this will be one more thing for the Left to be disappointed about in Obama.
They used small interfering RNAs or siRNAs, a new technology being developed by a number of companies, to hold the virus at bay for a week until the immune system could take over. Tests in four rhesus monkeys showed that seven daily injections cured 100 per cent of them.
I like a hundred percent. Of course, it’s a small sample.
While a cascade in LEO is something to be very concerned about, this Pop Sci article gets this quite wrong:
If a chain reaction got out of control up there, it could very quickly sever our communications, our GPS system (upon which the U.S. military heavily relies)…
Most communications satellites are in GEO, thousands of miles above LEO, and GPS are in twelve-hour orbits, also very high, but not as high as GEO. Most of our communications would remain intact, as would GPS.
