Everything had been tested out; the main drive fired for several days, stopped, turned around, and fired again. Now we coasted in to meet it.

It was a death trap in several ways. The sheer amount of energy blowing out behind was like a continual thermonuclear explosion, and although stars do that for millennia on end, no machine has ever done it before—let alone for thirteen years. And it wasn’t as straightforward as nuclear fusion or matter/antimatter annihilation; it was just the magic Martian energy sources stacked up, or nested, for a multiplicative effect. I didn’t have the faintest idea why it worked, and its designers were only a couple of baby steps ahead of me. All we knew for sure was that the scale model had worked, going out a hundredth of a light- year and back, with one pilot/passenger.

It was like successfully testing a motorboat, and saying, okay, launch the Titanic.

Which brings up another actuarial disaster waiting to happen: what if we hit something on the way?

It wouldn’t have to be another iceberg, real or metaphorical. Going at 0.95 the speed of light, a fist- sized rock would be like a nuclear bomb. We did have an electromagnetic repeller to keep interstellar dust from grinding us down to a sliver. But it wouldn’t work on anything as big as a marble.

Bigger things we could sense at a distance, and avoid with a quick blip from the steering jets, which explains our lack of fine glassware and china. Though if our cosmological models were right, such encounters would be rare. If we were wrong, it would be a bumpy ride.

There had been no serious problems with the test run. But we were going twenty-four hundred times farther.

Four engineers were still living on the iceberg. They would get us screwed down tight into the ice and connect our habitat with the storage area, where they’d been living the past ten months. Have to check the caviar and vodka supplies. (Actually, the modifications that allowed them to live there made the storage building a de facto alternate living area, if something made ad Astra uninhabitable, and if we somehow survived that event.)

We’d been talking with them for days, via line-of-sight laser modulation, and were glad to be able to aid them in a small conspiracy.

The plan was supposed to be that we not make physical contact with them, because they were all from Earth, and we were all quarantined because of exposure to Mars and Martians. They’d been talking it over, though, and decided to come say hello and be contaminated. Then they’d go back to Little Mars instead of Earth and wait for a chance to hitch a ride on to Mars. Which seemed like a better prospect than their home planet.

All four of our resident semi-Martians thought they’d be welcome, thumbing their collective nose at Earth. Of course, the two actual Martians didn’t understand why anyone would want to live on Earth in the first place. All that gravity. Humans everywhere.
