-
Researchers from Alterra Wageningen UR were able to grow and harvest ten different crop species on Mars and moon simulant. 'The total above ground biomass produced on the Mars soil simulant was not significantly different from the potting compost we used as a control' researcher Wieger Wamelink said. I wonder if the taste was as disappointing as that of normal dutch veggies :P
Hubble to Watch Historic Venus Transit, Using Moon as Mirror - 2 views
-
"Scientists are planning to use NASA's Hubble Space Telescope to observe next month's historic transit of Venus across the sun's face. But there's a twist. Researchers can't point Hubble anywhere near the sun, because our star's bright light could damage the telescope's super-sensitive instruments. So Hubble will watch the June 5-6 Venus transit by using the moon as a mirror."

aha. i suggested something like this a few years ago

For those who can't wait to be on Mars... ;-) - Oh and for those who want to see some REALLY cool panorama's: the moon @ http://www.panoramas.dk/moon/apollo-17.html
Russian Craft Fails to Head to Mars Moon - 1 views
-
Out-of-control Russian space probe may be 'most toxic falling satellite ever: A Russian space probe aiming to land on a Mars moon was stuck circling the Earth after equipment failure Wednesday, and scientists raced to fire up its engines before the whole thing came crashing down.

Is it just me, or is uncontrolled space junk re-entry becoming trendy?

this was a fantastic mission - ... what a pity!

Optimal Control Probem in the CR3BP solved!!! - 7 views
-
This guy solved a problem many people are trying to solve!!! The optimal control problem for the three body problem (restricted, circular) can be solved using continuation of the secondary gravity parameter and some clever adaptation of the boundary conditions!! His presentation was an eye opener ... making the work of many pretty useless now :)

I like when there are discussions evolving around entries

and on your problem with the RSS Tamas: its the same for me, you get the comments only for entries that you have posted or that you have commented on ...

Astrobotic announces expanded opportunities to send payloads to the Moon : Astrobotic Technology, Inc - 1 views
-
The remaining 229 pounds are available for $700,000 per pound, plus a $250,000 fee per payload to cover the engineering costs of integrating it into either the expedition’s lander or its solar-powered robot.
Technology Review: Blogs: arXiv blog: Physicist Discovers How to Teleport Energy - 4 views
-
He gives the example of a string of entangled ions oscillating back and forth in an electric field trap, a bit like Newton's balls. Measuring the state of the first ion injects energy into the system in the form of a phonon, a quantum of oscillation. Hotta says that performing the right kind of measurement on the last ion extracts this energy. Since this can be done at the speed of light (in principle), the phonon doesn't travel across the intermediate ions so there is no heating of these ions. The energy has been transmitted without traveling across the intervening space.

wonder if we can use that to power a moon base .... or on-board a SBSP satellite

I am not the physicist but I thought it might be interesting, from a space security point-of-view

Yes it seems really interesting and opens new possibilities. However this technology review article is not very good and the guy uses terms which have a precise meaning (like teleportation), which is different from the word we know... Quantum teleportation is what we use for designing quantum computers, but we are quite far from any practical applications. This energy teleportation will allow new scheme involving energy (if it is experimentally confirmed) which is very nice. However it seems this occurs in an entangled many-body system, which the only macroscopic one I know is a bose-eintein condensate (BEC). So it would mean infuse energy in the BEC by doing a measurement on one of the atom and extract it few millimeters away by doing a measurement on another atom. very far from any long distance power transmission...

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?

I'll have a look
