Mike Snead talks about aerospaceplanes and space based solar power I agree some of the things in the article but Mike Snead had said: While some argue that SBSP construction and operations can be undertaken with little or no direct human involvement—using robotic and self-assembly technologies—I [Mike Snead] do not share the optimism that these …
In theory, it is possible for a magnetic sail to launch directly from the surface of a planet near one of its magnetic poles, repelling itself from the planet’s magnetic field. However, this requires the magnetic sail to be maintained in its “unstable” orientation. A launch from Earth requires superconductors with 80 times the current …
Using light instead of wires to send information between the computer cores of a computer chip can be 100 times faster and use 10 times less power than wires. The new IBM technology aims to enable a power-efficient method to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires …
Technology Review talks to George Church about gene sequencing and the first commercial whole-genome sequencing service he launched last week with his startup Knome, based in Cambridge, MA. He is spearheading the Personal Genome Project, a nonprofit effort to make both the DNA sequence and the health records of many individuals publicly available. The project, …
A Senate committee approved a broad bill on Wednesday night to address climate change, a major step toward passage of a measure that would for the first time slow and then reverse emissions of the gases that scientists blame for the warming of the planet. I strongly support this legislation (and I would support stronger …
Carnival of space 32 is up at robot guy My entry was on my favorite proposed launch systems Bad Astronomy talks about using Mass as a verb Colony worlds talks about energy in space from space solar and helium 3 Space files mentions that the Planetary Society has raised $250,000 for a second space sail …
