  1. Proposals are now being taken for a permanent name for the target asteroid; http://www.planetary.org/blogs/emily-lakdawalla/2015/07221426-name-hayabusa2s-asteroid.html
  2. Is this required to be entirely US-made, or does congress allow e.g. russian engines?
  3. That diagram is for the Georgian alphabet, not the actual Georgian language.
  4. Maybe so-SLS still has a good bit of schedule margin and FH is already three years behind schedule.
  5. Return-to-flight NET September. Falcon Heavy has been pushed back in priority due to the incident, first flight NET Q1 2016.
  6. Because it's worthless drivel put together for clicks? Just take a look at anything else on that channel.
  7. Why did you feel the need to post this?
  8. In practice, non-US missile submarines are usually deployed in areas where they're easily defended and quite far from their targets, sometimes referred to as 'bastions': Chinese subs are deployed in the Bohai sea, French and British in the eastern Atlantic, and Russian ones in the Barents and White seas. This is because they're doctrinally intended as a durable second-strike capability, not for surprise attacks.
  9. Here's the above image, with fixed URL;
  10. No, you just need a halo orbit that isn't covered by the moon (i.e. roughly perpendicular to the earth-moon plane)
  11. The L2 point itself is occluded, but an orbit around it isn't necessarily.
  12. The first stage at least is known to be kerosene and RFNA, ROK confirmed after testing debris from 2012 launch.
  13. No tidal forces, they're both perfectly locked already.
  14. Many probes have imaging spectrographs, where you get readings for usually a few hundred wavelength channels per pixel. You can easily get true-colour images from that, but they usually aren't in the visual range and tend to have much lower resolution than the CCD sensors.
  15. The hubble image is not just an image from hubble; it's stitched together from lightcurve data from dozens of observations of charon occulting pluto. Trying to get colour out of that kind of dataset is a pretty sketchy process.
  16. They orbited a sat, confirmed by USAF radar measurements. That's it so far. The construction likely doesn't mean much for this launch in particular; it doesn't look like it'll be ready in time, there's no sign of a significantly larger rocket being ground-tested, and IIRC we don't even know if this launch is to be from Sohae.
  17. NASA has an actual priority list for large missions, as part of the decadal survey, and it puts a Uranus orbiter third after Mars sample return and a Europa orbiter. Given Europa and MSR projects have both officially started, an ice giant orbiter is likely to be the flagship after those.
  18. Psyche is going to be a lot 'newer' than Pluto, given we've already had a good look at Triton.
  19. They would be very unlikely to survive this long-NH has been out there for a decade, including a Jupiter encounter. That's a lot of radiation for something that size to have to deal with.
  20. There's PT1 and PT3. Decision is in august.
  21. It's much better than the Voyager 2 images of Triton's other hemisphere, given it didn't get any.
  22. Here's the base body structure for the Chandrayaan 2 orbiter; http://forum.nasaspaceflight.com/index.php?action=dlattach;topic=20324.0;attach=1031554;image
  23. Depends what kind of mission you're talking about-we're already confident we can do small missions with low-power payloads at Saturn, hence the encedalus life finder discovery proposal, but SEP is a different matter entirely.
  24. It's going to be transmitting stored data from the Pluto flyby (for over a year-bandwidth out there isn't great), then flyby another KBO in the 2018/2019 period. There are two targets still being considered, decision should be made which in august. Both are much smaller than Pluto, probably <100km diameter.
  25. Plan is for the demo flights to include one NASA and one vehicle provider astronaut each.
