Interest in asteroid missions has also been on the rise in the United States. In June, US President Barack Obama called for a manned trip to an asteroid. And late last year, the OSIRIS-REx project, also a sample-return mission targeting a carbon-rich asteroid, was selected as a finalist in NASA's New Frontiers Program,

The ambitious project will tap the resources of private enterprise to build several small scout rovers that will be shipped to the south pole of the moon via a single lander. Rock and earth samples will be returned to Earth for testing, then auctioned off to secure funding for the next phase of the plan

Well, the constellation program was a waste of money in its current form, overrun by delays and insufficient budget. We would have had Apollo 2.0 sixty years later, for what? At least now they are talking about going to asteroids, martian moons and stuff like that.
-
I agree that Constellation was a mistake. It is though a pity that now human Mars missions would certainly happen even later than initially hoped.

Russian Physicists Solve Radio Black-Out Problem for Re-Entering Spacecraft ... - 1 views
-
When spacecraft return to Earth, one of the tensest parts of the mission is the radio black out that occurs as the vehicle re-enters the atmosphere. Travelling at hypersonic speeds of between Mach 8 and 15, the spacecraft heats and breaks down molecules in the atmosphere causing a plasma to form. It is this plasma sheath that prevents radio communication.

The $30 million Google Lunar X PRIZE will be awarded to the first privately funded teams to build robots that successfully land on the lunar surface, explore the Moon by moving at least 500 meters (~1/3 of a mile), and return high definition video and imagery. The Google Lunar X PRIZE expires whenever all prizes are claimed, or at the end of 2015. As of midnight on December 31st, 2010, the team registration for the Google Lunar X PRIZE is closed. No additional applicants will be accepted to join the competition. ...too late

please see the act report on this from a few years ago - its on the wiki - should we maybe make an update analysis? any volunteers? Giusi?

breakthroughs vs. accelerated deployment in climate change mitigation technologies.

indeed. puts me in mind of the often reinvented private ACT idea. actually there's a bunch of interesting looking articles on his website. http://www.khoslaventures.com/khosla/papers.html . No sps in the solar one as far as i can tell :) found this bit intriguing too in that, albeit presumably out of context, it doesn't make sense ""The solution to our energy problems is almost the exact opposite of what Khosla says," declares Joseph Romm, who is the editor of Climate Progress, an influential climate blog, and a senior fellow at the Centre for American Progress Action Fund, a think-tank. "Technology breakthroughs are unlikely to be the answer. Accelerated deployment of existing technologies will get you down the cost curve much more rapidly than a breakthrough."" found this seemingly not very well considered piece (to be fair a blog post) by the guy http://climateprogress.org/2010/07/02/is-anyone-more-incoherent-than-vinod-khosla/ . maybe he's written some more convincing stuff in this vein somewhere.

"Mr Khosla (...) is investing over $1 billion of his clients' money in black swans" Well, with his own money his approach might be a little different :-)

no - its about Shell globally - all Shell .. these participations are just peanuts please read the intro of the CEO in the pdf you linked to: he does not even mention renewables! their entire sustainability strategy is about oil and gas - just making it (look) nicer and environmentally friendlier
-
Fair enough, for me even peanuts are worthy and I am not able to judge. Not all big-profit companies, like Shell, are evil :( Look in the pdf what is in the upstream and downstream you mentionned above. Non-shell sources for examples and more objectivity: http://www.nuon.com/company/Innovative-projects/noordzeewind.jsp http://www.e-energymarket.com/news/single-news/article/ferrari-tops-bahrain-gp-using-shell-biofuel.html thanks.
