The Japan Aerospace Exploration Agency spacecraft Ikaros now represents the first solar sail to have harnessed sunlight for both attitude control and propulsion, after it first launched May 21 alongside the Venus-bound orbiter Akatsuki.

It instead uses the sail for the humble but important mission of testing a potential orbit-cleaning tool.

yes, we did have a look at it, I think back in 2007 but its maybe time to re-assess it ... will put it on the miscellaneous list for Dejan, the new propulsion and plasma RF to come in January ...

In a jaw-dropping feat of engineering, electronics turn a person's thoughts into commands for a drone. Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.

The unique structure and properties of graphene and the morphology of the bulk graphene material make it capable of not only absorbing light at various wavelengths but also emitting energetic electrons efficiently enough to drive the bulk material following Newtonian mechanics.

Hard to believe this should actually work, but would be quite a breakthrough indeed. I wonder, since the material should build up a significant electric potential over time, thus, pulling back the ejected electrons. Well, the paper apparently is not peer-reviewed, and I found some rather critical comments in some forums. Let's see if the experiment will be verified by another research team in due course.

MAD Space debris

shared by Joris _ on 29 Nov 10 - No Cached

Being able to launch a satellite from a satellite has numerous potential benefits to the military and scientists, but those benefits depend on the smaller satellite not hitting the mother ship when it launches and going where it needs to go.If the sail can deploy as planned to its 100-square-foot size - about as big as a six-person camping tent - and can guide the smaller satellite to its planned re-entry, it would also illustrate a new way to bring satellites back to Earth and reduce orbiting space junk.
