+ - NASA Testing Frickin' Laser Communications->

Submitted by itwbennett
itwbennett (1594911) writes "The lunar laser communications demonstration will be part of the agency's Lunar Atmosphere and Dust Environment Explorer (LADEE) mission, which is scheduled to launch on Sept. 6. Here's how the system will work: When the satellite is in orbit around the moon and visible from Earth, one of three ground stations will shoot a laser towards its approximate location. The laser beam from Earth will scan a patch of sky and should illuminate the spacecraft at some point. When that happens, the spacecraft will begin transmitting its own laser towards the ground station and the two will lock on to each other. The technology should allow an upstream data rate, from the Earth to the spacecraft, of around 20Mbps and a much faster downstream rate of 622Mbps. That's roughly six times the speed that's currently possible with radio-based transmission, said Don Cornwell, mission manager for the lunar laser communications demonstration."

I really like this idea. However, instead of having it be completely random, why not have subject matter experts randomly chosen to create legislature related to their subject. i.e. Teachers drafting education bills, economists drafting bills related to the well being of the economy. There's nothing worse than people making laws about things they don't understand, present congress included.

No, we assume that every word in any Bible anyone can read is false because it is complete bollocks..."

The NT (Gospels in particular) can be seen as a reasonable historical account. There would be no reason for the authors (Mathew, Mark, Luke, and John) to reword things like what Jesus said. Can we reasonably assume that to the best of their memory, that is what he said? Yes we can. Especially since we take other authors words on far less controversial topics that were written hundreds of years afterwards instead of just 30.

A language that doesn't affect the way you think about programming is not worth knowing.
