Space: Telerobotics offers third way for exploration - ElectronicsWeekly.com
22 May 2012, 2:25 am
To do this, NASA would have to station astronauts at lunar lagrangian point L2 - a gravitationally neutral area of space which lies about 60,000 kilometres beyond the moon, in line with Earth. Mars is a bigger challenge, of course, as is Venus, which is ...

Distributed Online Optimization of Wireless Optical Networks With Network Coding - IEEE Spectrum
18 May 2012, 9:53 am
The former is solved in a distributed way based on the lagrangian-dual decomposition; the latter is solved based on the generalized bender decomposition. Simulation results are provided to illustrate the effectiveness of the proposed solutions.

As promised: Jupiter and moons seen by SOHO - DISCOVER
17 May 2012, 2:48 pm
Michael SOHO is about 1.5 million kilometers closer to the Sun than we are (about 1/100 of the total distance to the Sun), it is in an orbit around the L1 lagrangian point about where the gravitational pull of the Sun is equal but opposite to ...

An Alternating Direction Algorithm for Total Variation Reconstruction of Distributed Parameters - IEEE Spectrum
14 May 2012, 12:57 pm
Augmented lagrangian variational formulations and alternating optimization have been adopted to solve distributed parameter estimation problems. The alternating direction method of multipliers (ADMM) is one of such formulations/optimization methods.

NASA to put man on asteroid by 2020s - Worldnews.com
13 May 2012, 10:45 pm
Trojan asteroids are a population that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two lagrangian points of stability, L4 and L5, which lie 60° ahead of and behind the larger body. The most ...

Celebrity Billionaires Plan to Mine Asteroids for Profit but Also the Good of Earth - ThomasNet Industrial News Room
9 May 2012, 9:57 am
Mine for materials in-situ? Tow the asteroid back to the Earth-Moon lagrangian point L2 (a point of orbital equilibrium between the Earth and the Moon)? Put it into an orbit around the Moon? Put it into orbit around Earth? Or, the most expensive ...
