Jere Jenkins and pals at Purdue University in Indiana have re-analysed the raw data from these experiments and say that the modulations are synchronised with each other and with Earth's distance from the sun. (Both groups, in acts of selfless dedication,
he panel finds the 2005 order to find 90% of Earth-threatening asteroids 460 feet or larger infeasible,
No method for diverting asteroids has been experimentally demonstrated
Options include a "gravity tractor" orbiting slow-moving objects and tugging them off course with tidal tugs, a "kinetic" impact of a heavy spacecraft into an asteroid, or a nuclear explosion
DARPA for several years has been working on a program dubbed System F6 that seeks to prove that a cluster of small spacecraft can perform the mission of a large spacecraft by communicating wirelessly with one another in space
DARPA plans to launch three dedicated System F6 spacecraft either to low Earth orbit or geostationary orbit in mid-2013 to 2014
All the satellite-related systems (except for the rocket to launch it) are DIY programs -- designed so that regular people may also have the chance of developing and eventually launching their own.
I was saying that mainly because of some flaws - the piggy-pack installation, no dedicated stage, the limited control, ...
It is so far very funny, but once he can fill all the gaps, it should be an excellent initiative - although careful about the debris if anyone has its own ;p
his quote: "when art becomes practical, we call it technology;
when technology becomes useless, we call it art" ...
this is probably the later one ....
Policy makers would be much better placed to combat the effects of global warming if scientists had access to accurate measurements of the Earth's radiation balance from a dedicated satellite, claims an international group of physicists.
it estimates that the satellite could cut a decade or more from the time needed to make useful projections of global temperature at the end of the 21st century.
When Australian mobile provider Telstra offered its mobile customers unlimited data for two separate days this year as compensation for network outages, some customers took it as a challenge to download as much as they possibly could in one day. On Sunday, 27-year-old Sydney resident John Szaszvari outdid himself and everyone else by ploughing through almost a whole terabyte of data.
