Comment Re:Leave one in orbit? (Score 1) 195

Shuttles can only last about two weeks in orbit before they run out of reactants for the fuel cells. They wouldn't last much longer, even if you cut power consumption, because the hydrogen in the fuel tanks would continue to boil off whether your using it or not. Soyuz can stay in orbit much longer due to the fact it gets its power from solar panels and, when docked, directly from the space station.

My favorite writing blunder was in the back half of the last season. Most fans who watched "Someone to Watch Over Me" were convinced that the Piano Man was Starbuck's dad and Daniel, Cylon #7, which would have helped explain how Starbuck resurrected on Earth and how she started playing "All Along the Watchtower." RDM's take on it, though, was something along the lines of, "Yeah, I can totally see how you guys think that, but the thought hadn't even crossed our minds. Sorry for giving you that idea."

I still think, in this case, the writers are wrong and the fans are right.

It does seem miss some instances of time travel in the middle of a story. For instance, near the end of Smith and Jones, he goes back to the beginning of the day to take his tie off at Martha, and during Vincent and the Doctor, there were two round trips from 2010 to 1890, of which only the first leg is reported here.

OK, I may be over-nerding here even on a nerd topic.

If you want an in-universe explanation, I suppose some hand waving could link it to how the Doctor was able to regrow his hand in The Christmas Invasion. I suppose the writers could chalk it up to her being within 48 hours of her (re)generation cycle, so it was just superhealing rather then regeneration. Better explanation, though, is it's a TV show. The writers can make whatever they want happen, and it probably wasn't worth casting an extra actress for a 30 second scene.

Weight. If you use nuclear power source, you've got to bring your fuel with you, where as with solar, the fuel is already packed away safely in the sun; you just need to bring a collector. Mars, unlike the outer planets, is still close enough to the sun that you get a reasonable amount of power from solar cells, if you have enough square footage, so solar wins the power/weight ratio contest. Besides, these things weren't built to survive the winter at all; the design requirements only called for three months.
