If he entered the gasification chamber through the hatch he’d just drive more sunstone out as he pushed his way through it. Back in the maintenance shaft, he warily tested the rim of the gash with one fingertip. The damaged stone was still warm from the collision – with a microscopic Hurtler, most likely – but the escaping air had carried away enough heat to render it traversable. He clambered out into the void and made his way along the torn edge of the hull, hand over hand; the distance was so short that this was faster than messing around with his jetpack.

‘I’m with her!’ Agata announced excitedly. ‘She’s conscious, Ramiro. She’s putting on her cooling bag now.’

Ramiro started humming with relief; embarrassed, he muted the outwards channel on the link until he’d regained his composure. ‘Be careful coming back,’ he managed.

Agata replied, ‘Don’t worry, we will.’

As Ramiro climbed into the chamber small pellets of sunstone bounced off his jetpack and faceplate; he had to force himself not to raise his arm instinctively to swat them away like insects, as that would only have added energy to the swarm. He took the jar from his tool pouch and daubed resin over the nearest part of the inner wall, then tugged the tarpaulin out of the gap under his belt and fixed one edge in place. There were no ropes or handholds in the chamber that he could use to brace himself, but he could apply pressure by closing his hand over the whole exposed thickness of the wall, clamping the fabric of the tarpaulin against the resin until it adhered.

He pushed himself off from the wall to reach the far side of the chamber; he hit it with a jolt but managed to grab the rim of the gash to keep himself from bouncing. The tarpaulin was wider than the gap he was trying to cover, and once he had it secured at both ends the pellets of sunstone were too large to work their way around the sides.

Ramiro paused to take stock. There was more sunstone in the store behind the chamber; they’d probably only lost about a twelfth of their total. If Tarquinia was safe, the next most urgent matter was checking on Azelio. Getting the gash repaired and the entire Surveyor airtight again would take a long time, but as an interim measure they could seal the doors to the damaged cabins and concentrate on the cooling chamber while they still had enough air in tanks to keep them from hyperthermia.
