Location: Low Earth Orbit, International Space Station 2 (ISA Orbital Platform #001)

-----------------------------------
Alarms. Sirens. A voice over the intercom.
The captain woke up suddenly. The hell? he thought, reaching over to turn the intercom on.
"This is the captain, what is it? And can it wait until morning?"
"No sir, no it can't. ISA headquarters wants you on the line, now. Why... you'll see, soon."
"Fine. Up in a minute."
-----------------------------------
The captain glided into the communications room, displacing the lieutenant stationed there. He switched the main videophone to the dedicated line to ISA headquarters in Geneva, and saw the heads of the Administration there, looking decidedly ill.
"Good morning. What's the emergency?"
The head of Observation stepped up to speak, which in and of itself immediatly alarmed the captain. Observation was tasked with spotting threats to Earth, and, if necessary, redeploying one of the DSCVs to eliminate it. If he was alarmed...
"Captain, something's come up. It looks like... we missed one. An extremely large comet, it looks like almost the size of Pluto originally, came into the inner solar system along the plane of the solar system on the far side of the sun. It managed to miss slamming into the sun, but it got slingshotted around at extremely high velocity. On a collision course with Earth."
"Wha- how did you miss that!?!?!?!?"
"It was coming almost right out of the sun, hell it was actually in the corona! You know we can't look into that, and what were the odds of something actually making it through that?"
"I- I understand. Anything else?"
"Yes. The comet seems to have fragmented significantly, enough so that it seems unlikely it will actually manage to hit Earth hard enough, or with enough pieces, to actually wipe out humanity. But enough of it will assuredly hit to wipe out most of civilization."
"How long to first impact, then? How long do we have to get people to safety?"
"... The first impact is in five minutes, captain. It'll hit just of the coast of Australia, and a second chunk is projected to hit ten minutes later in the Sea of Japan. The comet will take twenty-seven hours to pass Earth completely, barraging the daylight side. One of our people put it best, on hearing the news: 'With the dawn comes the fire.' By dawn in Geneva, or what's left of it, tommorow, nothing will be left."
"What do we do? What can we do?"
"Nothing. There's nothing you can do. We did manage to get the Secretary-General on the phone, though, and he agrees on our one, final order to you: Attempt to uphold, and, if necessary, reinstate the ideals of the UN, assuming anything at all survives. Now if you don't mind, we'd like to spend our final hours with our families, and I imagine the crew will want to say goodbye to its families, too. For the last time, goodbye, and good luck."

The comet has just finished with its bombardment of Earth. Most of human civilization has been destroyed. Almost all coastal areas have been destroyed. Low-lying areas are flooding rapdily due to all the water vaporized by ocean strikes raining down again. First things first: Who are you? List name, rank, age, a short description, and position (job, not actual location) on the station.
Available ranks:
1 Captain
1 Commander
2 Lieutenant Commander
7 Lieutenant
28 Ensign
Once people have signed up initially, we'll move on.
