ASMO - ESMO .... hmmmm who copied whom?

nice article on space debris

A new social space news and networking site.

Some ideas on debris mitigation.

A good example of how loosing perspective makes so-called "novel ways" actually "rubish ways"

here the paper: http://arxiv.org/abs/1104.1401 well spent defence funding ....

For the first time ever, astronomers have discovered a ring system surrounding an asteroid. The finding is a complete surprise to planetary scientists, who are yet unsure exactly how such rings could have formed. The cosmic bling was found around an object named Chariklo, which orbits in a region between Saturn and Uranus.

At a meeting of the American Geophysical Union in San Francisco in December, he reported an average figure that was between 0.005 and 0.008 per cent greater than the value for Earth's mass established by the International Astronomical Union. A disc of dark matter around the equator 191 kilometres thick and 70,000 km across can explain this, he says. Harris has yet to account for perturbations to the satellites' orbits due to relativity, and the gravitational pull of the sun and moon. Maybe relativistic GPS could improve this even further? As a side note however, the Juno spacecraft flyby showed an gravity acceleration which matched the calculations, casting doubts on the earlier calculations.

The Wall Street Journal hears that the search firm is preparing to build 180 "small, high capacity" satellites that will go into low orbit and provide internet connections to underserved areas

sorry, did not see your earlier post ... fully altruistic move of course as they claim

actually I posted about it first :P

I still think, the lizards have evolved at an unexpectedly high rate and have now taken over the satellite...

Good news for fundamental physics and Earth system science, femtosecond lasers are now about to achieve space qualification thanks to fibre optics!  Applications include high resolution spectroscopy, absolute laser ranging, mapping of the geo-potential and testing of the theory of general relativity to name a few!

nice paper by the Koreans, did not know that they had already such a laser in orbit for a year. How much would this type be upscalable for our needs? in case we have not, we should reference it

Shows you stuff... in space!

It is an old one, but it was mentioned in some discussion ... Mainly based on this paper https://arxiv.org/abs/astro-ph/0102126

The party is over.

Some locations on Mars are known to have water ice just below the surface, but how much has remained unclear. Dundas et al. used data from two orbiting spacecraft to examine eight locations where erosion has occurred. This revealed cliffs composed mostly of water ice, which is slowly sublimating as it is exposed to the atmosphere. The ice sheets extend from just below the surface to a depth of 100 meters or more and appear to contain distinct layers, which could preserve a record of Mars' past climate. They might even be a useful source of water for future human exploration of the red planet.

OHB and Luxspace venture to ensure human life on the Moon! Research on O2 production and others.....

Has BH at least completed an orbit yet? Or are they still at 10mins in microgravity?
