  • ESA is freezing spending
  • France is planning to boost its funding by 12 percent
  • ESA selected Thales Alenia Space and OHB Technology to build the satellites, but the production contract is still bogged down by Germany's complaints about the distribution of MTG work between France and Germany

    no much news in regard to the january's talk of Dordain althought just a thought : what if ESA tries to make money - as CNES does - rather than just spending it ?

    to begin with european industry (and probably governments) would complain that ESA was taking business away from industry? or any part that started to make money would be quickly spun-off

    really bad interview in my view ... btw: how is CNES making money and how much?
  • Joris _ on 09 Jun 10
     
    CNES is known to be a semi-autonomous agency in the sense that it can auto-finance parts of its activities. Besides the money coming from the state, money comes from the participation of CNES in private companies (e.g. Arianespace) and its own activities (e.g. SPOT among others...). It is about 400M€ per year (almost a class-M mission in Cosmic Vision). For the figures (in French): http://www.cnes.fr/automne_modules_files/standard/public/p4354_c050f7963b54a839a843723401bfddf2budget.pdf

  • At a workshop last month in Washington, D.C., NASA canvassed the scientific, human spaceflight and planetary defense communities about their priorities for a mission to a near-Earth asteroid.
  • an asteroid mission is possible as early as 2019 using a pair of enhanced Orion spacecraft with a two-person crew.
  • November 2019 and spend three months flying more than 7 million miles to an asteroid that's about 33 feet across.
  • ...2 more annotations...
  • he crew would "park" their vehicle nearby and spacewalk over
  • After about five days the crew would climb back into one of the capsules and spend three months flying home.

    mmm, I think that if we manage to travel at 99.999998 per cent the speed of light, we'll have the technology to deviate these atoms ! one way could be a super strong magnetic field, or a super laser that would act as an ice breaker with the radiation pressure (the good thing is that light always travel at the speed of light, even if you are at 99.999998 per cent the speed of light)

2001 monolith moon crowdsourcing private-spaceflight sci-fi fun

shared by Luís F. Simões on 07 Jan 11 - No Cached
  • Jamie found a somewhat amusing little essay on putting together a crowd-sourced mission to put a monolith on the moon. The author estimates it would cost half a billion dollars, which is a sum he thinks could be raised.
  • Let's raise the stakes. I propose raising half a trillion dollars to develop a time machine and put a monolith in Olduvai Gorge three million years in the past to influence Astralopithecus Afarensis evolution. Our very existence might depend on it.

    ESA's article on the consequences for ISS: http://www.esa.int/esaCP/SEM6GJUTTRG_index_0.html What is not clear is if the rocket that failed is the same variant as used in manned missions. [Edit] According to this article: http://www.interfax.com/newsinf.asp?pg=3&id=268437 "The first and second stages of the Soyuz-FG space rocket used for manned launches differ from those of the Soyuz-U, but the third stage [the one that failed - MR] is identical in both rockets". Thus the stay of astronauts currently at ISS may prolong a little bit.
