WHAT DID THEY JUST SAY? Now they're using solar cells and lithium-ion batteries?! Who predicted that? --- Mark IV |

Since spacecraft have been using solar cells and rechargable batteries for about a half a century now, it would be hard to say who predicted such a thing. Though your dim little mind probably thinks they are running the engines of a spacecraft with electricity. -- Jim Pennino Remove .spam.sux to reply. |

So, Jim -- what's the mission of this thing?

By virtue of the fact that it *is* military, right off the bat we know that cost has a far different priority. The military can not only spend more due to the fact that they won't go out of business, but they WILL spend more due to nepotism. Cost overruns are business as usual. Goals and considerations are what they are. Spying. So no, if it were civilian you'd not have the equipment aboard for that. Designs constraints? Flight is flight. If a civilian group wanted a reuseable orbital with autonomous reentry the design wouldn't have "little in common". It looks just like the space shuttle, but smaller. That's why it's called the "minishuttle" by the press. But among the "technologies to be tested", we see... "lightweight electromechanical flight systems". That wouldn't be something done for half a century, or it wouldn't be technologies to be tested. So your "dim witted" comment would be best done to the mirror, or better yet...not at all. --- Mark IV |
