  1. Corporations selling mined resources is definitely legal under the treaty; this has been tested. NPO Lavochkin auctioned off some lunar soil samples returned by soviet probes.
  2. Doesn't work for animals that are difficult or just expensive to keep in captivity. Look at rhinos or tigers-the fact they're used as 'food' is a major part of the problem.
  3. I did. I regret having done so, but I did. You might want to add evolutionary biology to your reading list as well as ecology, and probably throw in a definition of the word 'competition' in the context of biology while you're at it.
  4. It's basic ecology. You're acting like there's no such thing as an ecosystem.
  5. They basically assume you have a TV, and send you letters about the licencing law if you haven't paid, but if you don't respond nothing happens. It costs more to send an inspector then they get out of TV licenses, and the few inspectors they do have don't qualify for any kind of search warrant (so can't enter without your permission) rendering them pretty much useless.
  6. Voyagers 1 and 2 took 2 years to get to Jupiter. Juno, the last Jupiter mission launched, is going to take 5 years. JUICE, the next, is going to take nearly eight.
  7. Up to 3U is the standard size for the cubesat deployment system (PPOD), but in practice was found to be too small for real technology missions. Larger ones require specialised deployment systems, but are still easier to design and integrate.
  8. Can you see Europe or the US working with them? Given what happened to Exomars, neither have the requisite slack in their planetary budgets.
  9. Looking into it a bit further, the only confirmed Indian plan is the 'Mars Observation Mission' in 2016/17; anything more is nothing but speculation.
  10. India seem to be focusing on an orbiter mission for that opportunity, not a lander.
  11. All NASA hardware is ultimately 'commercial'. They can act as a systems integrator, but they don't actually produce anything.
  12. And even that's assuming there wasn't a major systems failure, when we've no evidence of that. Given the development issues with the airbags in particular, there's a good chance we're looking at the result of a bounce or a too-hard initial impact.
  13. Small sats have made interplanetary missons before (e.g. the 20kg Shin'en venus flyby craft), but this would be the first built to the cubesat standard.
  14. Although, in practice, most hydrogen engines run extremely fuel rich, and most of the exhaust is hydrogen.
  15. In a chemical rocket, oxidiser and fuel are both propellant, and both leave the rocket. For example, a hydrogen-powered rocket produces energy though the reaction of hydrogen fuel and oxygen oxidiser to form water, which is what actually forms the exhaust.
  16. The 2D versions were never available to players, they were internal.
  17. It seem more likely the 'detection' was itself an anomaly. There were also a bunch of false fire alarms, could be a general electronics or alarm system issue.
  18. It appears so far that there was no ammonia leak into the interior of the station, but there might have been a leak from one cooling circuit to another.
  19. Virus' can't reproduce independently, they're dependent on host cellular machinery. If that's enough to qualify as 'alive' then chromosomes are living organisms.
  20. They moved to indirect management in the 90s, collating a bunch of institutes into CASC (of which CAST is a part) and a competitor called CASIC. Both have diversified into commercial contracts and even non-aerospace areas since; one of CASIC's institutes rather infamously makes DF-21 ballistic missiles, cars, and refrigerators in the same factory.
  21. There seems to have been somewhat more government support since I posted that, but it should still be noted that CAST is not directly government-managed.
  22. It's highly doubtful life could evolve in a non-polar solvent like methane; polar solvents support micelles which allow for increased concentration of potentially biogenic chemicals, whereas non-polar solvents don't. If there is life on Titan, the most likely place would be the purported subsurface water-ammonia ocean.
  23. Needing to have a transfer window available every orbit makes absolutely no sense if you're using a space system to assemble a spacecraft. Being able to ignore that kind of constraint is the point, surely?
