A little further along the corridor she spotted the shattered porthole window she had tried to repair the previous day. She shuddered. In the hull of the ship was a scorched hole where they’d been hit. It looked as if a missile had blasted through the metal, a black starburst of soot radiating away from the hole.

Commander Bovarin was heading around the corner towards the service modules. She and Eliot trudged after him, heavy in their suits.
The service modules were in uninhabited parts of the ship. Beneath the crew module, on the lowest deck, sandwiched between the equipment rooms and the escape shuttle. The service module was the compartment that contained the fuel cells and batteries that provided power to the spacecraft, as well as essential computer systems like guidance and thermal control. Igor pulled open the aft fuselage access door to reach it and when Astrid peered inside, her heart sank. The entire module was a tangle of melted copper wiring. She felt a sickening swoop in her stomach. The service module was their lifeline. Without it, they had no hope of powering the ship, and without power, there was no way to continue the mission.
The prospect of making it to Terra-Two was receding from them. Astrid’s eyes began to sting.
As Igor pulled through the wreckage, she heard his groan of despair over the headset. But his words came to her as if from a vast distance. ‘
In the end, they settled for doing the only thing that they could do and patched up the holes in the wall, so that the crew would be able to access the lower deck without having to climb into spacesuits. Then they returned to the middle deck in silent misery, running through the motions of shutting down the EMU systems and other components, changing out batteries and cartridges.
‘We don’t have much time left,’ Eliot said. The entire EVA had taken six hours.
‘Yes…’ said Igor quietly. ‘The service module is just too damaged to support this crew. We don’t have the spare parts we need, not on this ship.’
‘We can’t just give up,’ Astrid said.
‘No. We can’t just give up. But we have to face the fact that the mission has changed now. My job now is to get the crew home safely.’
‘You mean… abandon the mission?’
‘We still have one serviceable escape shuttle.’ Igor was taking apart his EMU as he spoke. ‘It’s enough to get six people back home.’
A chill ran through her. ‘Six people,’ she said softly. And behind both their words, the grim understanding that four people would have to stay behind. Astrid didn’t know what would be worse; suffocating in their crippled ship or heading back to Earth in the cramped shuttle, heavy with failure and regret. There would be no gravity on the shuttle, and with each passing day, during the months it would take to return, their bones would begin to turn to dust. Even as Astrid imagined it she knew it wouldn’t be her. She knew she would not abandon the
‘We’ve fought a good battle,’ Igor said.
‘No,’ Eliot and Astrid said in unison.
She remembered what Poppy had told her, about watching Harry and Jesse steer the
‘Is there no chance we can be rescued? Couldn’t a resupply rocket arrive with a new service module attached, or one with all the spare parts we need?’
Such things had happened on previous missions. Two years earlier a centrifugal module had broken on
