Wormhole Created in Lab Makes “Invisible” Magnetic Field

I hope this isn’t a hoax, but Space.com is pretty darned reliable, so take this for what it’s worth.

“This device can transmit the magnetic field from one point in space to another point, through a path that is magnetically invisible,” said study co-author Jordi Prat-Camps, a doctoral candidate in physics at the Autonomous University of Barcelona in Spain. “From a magnetic point of view, this device acts like a wormhole, as if the magnetic field was transferred through an extra special dimension.”

Next Big Future: DARPA funds next phase of XS-1 spaceplane project

Darpa has now awarded three contracts to Boeing, Masten Space Systems and Northrop Grumman, which will subcontract Virgin Galactic, to develop a demonstration vehicle, identify and reduce risks to the technologies on board, and come up with a plan to build and flight-test the spaceplane. Each of three companies got $6.5 million for Phase 1B of XS-1 program.

Electric Solarwind Sail for Spacecraft

A paper analyses the potential of the electric solar wind sail for solar system space missions. Applications studied include fly-by missions to terrestrial planets (Venus, Mars and Phobos, Mercury) and asteroids, missions based on non-Keplerian orbits (orbits that can be maintained only by applying continuous propulsive force), one-way boosting to outer solar system, off-Lagrange point space weather forecasting and low-cost impactor probes for added science value to other missions. We also discuss the generic idea of data clippers (returning large volumes of high resolution scientific data from distant targets packed in memory chips) and possible exploitation of asteroid resources. Possible orbits were estimated by orbit calculations assuming circular and coplanar orbits for planets. Some particular challenge areas requiring further research work and related to some more ambitious mission scenarios are also identified and discussed.

Unexpected findings: Small asteroids can be flying rock clusters or even clouds of dust surrouding solid rocks — ScienceDaily

What seemed to be rock-solid assumptions about the nature of small asteroids may end in rubble or even a cloud of dust. New findings suggest small asteroids can be a flying cluster of rocks or a cloud of dust with a solid rock at its nucleus.
