I closed the airlock door with a quiet thud and I locked it, knowing it might have been for the last time. Outside it was still dark, just before dawn. The instant the sun peeked out over the horizon its pale light would hit the plains, creating long shadows.
I stood for a moment looking at the stars through the glass, while the valves let out some air to equalise the pressure with the outside. My suit, which at first almost adhered to my body, was now expanding, giving me a clumsy look.
The pressure balance was reached and the exit door opened. Even though the suit was heated, I perceived a huge difference in temperature. It could rise well above ten degrees Celsius on a summer’s day, but it could drop to minus ninety at night. And the hours before dawn were always the coldest.
I switched on the torch and went out, moving with caution. I hoped nobody had seen me leave. Robert was lost in dreamland and had certainly no intention of getting up at dawn, but Hassan, in spite of all that had happened, carried on with the mission, especially now that he was in charge.
He kept repeating that in a few months more personnel and materials would arrive. I was not convinced. Yet another major failure was looming and, at the moment of need, those in Houston would come out with another excuse.
Despite the heavy load I was carrying, I walked with ease. With gravity a little more than one third of Earth, everything was lighter, and thanks to my experience over the years I was accustomed to moving with skill on a rough terrain, even when wearing that uncomfortable suit.
I opened the hatchback of a rover and loaded my provisions; then I climbed into the front of the vehicle and activated the pressurisation. The life support pumps pushed the gasses inside, creating the correct mixture for breathing. When the green light came up on the dashboard, indicating the process was complete, I removed my helmet and suit. I laid them in the back, settled myself in the driving seat and fastened the seatbelt. As soon as the engine started, an alarm would go off inside the station, alerting them to the unexpected activation of one of the two rovers.
There was still time to go back. I just had to don my suit again, return to my quarters and climb back into bed. Nobody would notice. But, even if my act might appear senseless, to me it seemed the most reasonable thing to do. There was nothing more for me in the station, beside pure survival. Perhaps not even that certainty.
I studied the data gathered the evening before on the on-board computer screen. It wasn’t much, but it was all I had. I took a deep breath, and then turned on the engine and put my foot down. I was moving towards another certainty: that of my death. But I had started doing that a long time earlier, when I accepted the invitation to join the mission.
