Caltech and Grumman partner on Space Based Solar Power Initiative
Posted by Klaus Baldauf in categories: solar power, space travel, sustainability
SSPI approach: • Enabling technologies developed at Caltech • Ultra-light deployable space structures • High efficiency ultra-light photovoltaic (PV) • Phased Array and Power Transmission • Integration of concentrating PV, radiators, MW power conversion and antennas in single cell unit • Localized electronics and control for system robustness, electronic beam steering • Identical spacecraft flying in formation • Target is specific power over 2000 Watts per kilogram. This would cost competitive with ground-based power.

Major gravity experiment recreated aboard a satellite
Posted by Genevieve Klien in category: space travel
A spacecraft was used to “drop” two objects and test their rate of fall. The new, super-precise findings confirm objects will fall at the same rate (in the absence of air resistance) — and that when it comes defining the effects of gravity, Einstein got it right.

Skycorp planning to make space industries
Posted by Klaus Baldauf in category: space travel
The moon is largely made up of metal oxides that could yield new supplies of platinum — perhaps enough to drive prices for the precious metal down to $300 from $1,400 an ounce today. Processing metals on the moon does not require chemicals. Different levels of heat can be used to make different metals. Cheaper platinum will make fuel cells that are so much more effective than combustion engines.

NASA X-Ray Navigation System Aims to Be a Galactic GPS for Space Exploration
Posted by Genevieve Klien in category: space travel
The navigation system uses x-ray light emitted from pulsars the same way global positioning systems use atomic clocks, which could eliminate the need for costly ground-based guidance systems.
