If you saw Stargate Universe this week, read on. If not, spoilers ahead.
Glad you decided to stick around. So, last week on SGU, Destiny fell out of hyperspace, presumably for a good reason. The initial assumption was that the ship was completely out of power and that the engines simply quit. At this point, I thought “well just open up the solar panels and recharge the batteries. This is an ancient ship. They surely had solar powered spaceships.” But I digress.
Luckily, the remaining shuttle still had power. So they determined that there were three planets orbiting the nearby star that might be habitable. The ship, it seems, dropped out of hyperspace where it did to give those aboard the best shot of survival. It appears that the ship is on a course that will slingshot it around one of the system's gas giants as a breaking maneuver. The crew guesstimates that the maneuver will put them on course to intercept the orbits of the three possibly-habitable planets. But no. Turns out, the ship comes out of the slingshot heading directly for the star. Bad for the people onboard.
Long story short, the shields were still up, but nothing else had power (including internal sensors), so they assumed the shields were down. Everything turns out okay, but there is some suspicion that Dr. Rush knew that the ship dropped out of FTL and shut down so that it could fly into the star, open its solar cells and recharge the batteries. To which I immediately said: “No shit, McFly.” I knew that and I don't have a degree in astrophysics, anthropology, or ancient spaceships.
