  1. Re:supply lines to ISS already secure on SpaceX Falcon 9 and Dragon Make It To Orbit · · Score: 1

    Just to clarify, a Progress can carry that much away from the station, but you don't get it back in useable condition. The Dragon can (in theory at least) not only carry it away, but bring it back down safely.

    Small re-entry capsules have been flown on Progress, but the capacity is limited to a few 10s of kg.

    Also bear in mind that price for a seat on a Soyuz is what is advertised, not what is necessarily paid. NASA doesn't seem to be very good at negotiating prices and I'm not aware of any of the "Tourists" saying exactly how much it cost them. Informed speculation ranges between "One seat sold pays for the whole flight" to "There's a healthy profit margin built in".

    Redstone used liquid fuels too, alcohol and liquid oxygen. WvB was heavily involved in its design.

  3. Re:Voyager 2? on Evidence For 200-Year-Old Comet Impact On Neptune · · Score: 1

    The Shoemaker-Levy impacts were happening on the side of Jupiter not visible from Earth. Voyager, Galileo and Ulysses all had a different view of the planet, so the view from 3 billion miles away is better than "none at all".

  4. Re:might as well buy a netbook for that price on Kindle Finally Ready For Global Distribution · · Score: 1

    The Kindle is shipped direct from the USA to wherever instead of from the local Amazon at what appears to be a not free cost, and attracts import duties of various kinds on top of the total. Adds about 40 quid (65ccu) to the basic price.

    Unfortunately for your ice sheet theory, the large bluestones are all there is in the area. Glaciation would also have brought huge quantities of identifiable smaller bits right down to gravel size.

    Being a journalist on their press release distribution list will probably be the quickest way, otherwise just keep refreshing the SpaceX site.

  11. Re:If light is affected normally by gravity... on Does Antimatter Fall Up Or Down? · · Score: 2, Informative

    One model for anti-matter is that it is a normal particle travelling backwards in time. The energy from a particle/anti-particle annihilation is the energy released by it changing direction under this model. As far as the particle is concerned, it is behaving normally in a gravitational field by falling downwards, but when we look at it from our usual time axis it appears to be falling up.

  12. Re:Race goes on on US Urged To Keep Space Shuttles Flying Past 2010 · · Score: 1

    The shuttle has *no* abort modes while the SRBs are burning, once they've lit they are going to go somewhere and a problem will destroy the orbiter. Having only one of them light would be a Really Bad Day.

    The backup for a Soyuz parachute failing to deploy is to jettison it and use the backup instead.

  13. Re:Perhaps not the brightest of ideas. on US Urged To Keep Space Shuttles Flying Past 2010 · · Score: 1

    The Soyuz pad at Kourou won't be set up for manned launches. It may get that capability added, but not before 2010. And besides, the launchers and manned craft will still come from Russia and a large proportion of the ground crew will be Russian. It's also French territory and US-France relationships haven't exactly been strain free...

  14. Re:Only sub-orbital? on 2008, The Year of the Spaceship · · Score: 1

    Using White Knight 2, the carrier aircraft, not Spaceship 2. Take a small rocket that does have enough delta-V for orbital insertion up on the carrier aircraft instead of a Spaceship 2.

    It may also involve a Spaceship 2.5 without the passenger capability that acts as a flyback second stage and releases a third stage at apogee.

  17. Re:How do they change over? on U.S. Mass Declassified Documents At Midnight · · Score: 1

    It's been working in the UK for years, although the minimum period is 30 years rather than 25 and some material will have a 50 or 100 year delay. The Public Records Office tends to store material by date rather than by subject, so the relevant shelves become accessible to researchers at the beginning of each year. Indexes may or may not be available, actually finding a declassified document still takes a lot of effort.

    This year we've had a look at the timetable of Harold Wilsons resignation, and found out an Argetinean invasion of the Falkland Islands was predicted. Apparently not much happened in 1976.

  18. Re:Way too dangerous? on NASA Proposes Manned Asteroid Mission · · Score: 1

    It's unlikely. Neither of the asteroids that have been orbited and landed on so far have shown any sign of surrounding debris and, apart from a couple of small satellites, not have any of those pictured in passing. Obviously they'd avoid any targets showing signs of cometary behaviour at this time.

    abandoned at sea, if you recover, it's yours

    Not true. Under international maritime law, abandoned at sea, if you recover, the original owner (who may now be an insurance company) must be given the opportunity to reclaim it on payment of reasonable (set by an admiralty court) expenses to you.

    In any case government property remains government property, and you must have that governments permission before attempting salvage operations. See the fun Curt Newport had recovering a sunk Mercury capsule recently.
