Ash returned to the Control Centre accompanied by Parker, just as the alarm was silenced by a sharp order from the Commander.
Ash brandished a small metallic device in his hand.
“I’ve scanned the reactor’s panels, Commander,” he said. “The scanner is just analysing the results. Then we’ll know who caused the explosion.”
“No time for that now, Ash!” blustered the Commander. “We have to get the back-up air pumps working. You and I will have to spacewalk around the outside of the station. Parker, you’re in charge of switching the air supply inside. And take charge of those blasted kids!”
“Stick with me, you three,” said Jane Parker to George and his friends. “I’ll need you to operate the pumps, nobody can be spared from in here.”
As they left the Control Centre, George looked back at the scattering of staff hunched over their screens. He was feeling worried and frightened, but they looked even more worried and frightened. Several of them were calling out various readings to each other.
Mr Snodbury was cowering behind a bank of computers, frantically trying to connect a phone call with his mini-screen and getting nothing but a ‘No Signal’ response.
Less than two minutes later, Ian Ash and Commander Ferguson were climbing into spacesuits as fast as they could. Parker was beside them, ready to operate the airlock through which Ash and the Commander could reach the outside of the station. Behind her, George, Josh and Amira stood ready at the controls of the back-up air pumps.
“Why have they got to get outside?” asked Josh. “Can’t they fix the air supply from in here?”
“No,” said Amira. “The explosion destroyed half the mechanism. They’ve got to find a big air pipe that’s dangling out there, and connect it up to the station by hand. Then we can switch the air supply over from these controls.”
“And if they don’t manage it,” said George, “we’ll start running short of air to breathe in a matter of minutes.”
Parker pulled a lever and the airlock door slid aside with a hiss. Ash and the Commander clicked the helmets of their suits into place. They both tapped the sides of their helmets and shook their heads.
“Communicators aren’t working,” said Parker. “Minor problem, I guess, compared to everything else.”
The two bulky figures shuffled into the airlock. Coloured lights blinked on the large, rectangular packs attached to their backs. Small jet nozzles poked out of the packs – these were what they would use to move around in space.
The airlock door hissed shut, Parker operated a second lever, and the outer door in front of Ash and the Commander glided silently back. Through a clear panel in the airlock door, George could see them switch on their backpacks and jet out into the inky blackness beyond.
“Keep an eye on that indicator,” said Parker, pointing to a tall red panel just above George’s head. “When it goes green, the pipe’s been connected. Then we switch the pumps on.”
Using her mini-screen, Amira tried to tap into the sensors outside the station, so that they could see what Ash and the Commander were doing.
All she could get was a fuzz of static. “They must be broken,” she said. “Like the suit communicators.”
They waited. Without being able to see or hear the men outside, they felt more tension with every passing second. Half the lights had fused along the corridor in which they stood. The shiny walls and floor had seemed sleek and high-tech only a few hours earlier. Now they seemed gloomy and sinister. The corridor was eerily quiet.
George started wondering where Dwayne had got to. Why had he been sneaking back to the crew cabins? What was he up to right now?
Suddenly, Josh cried out. “Oh no! Look!”
They gathered at the window in the airlock door. To their horror, they could see a spacesuit spinning rapidly away from the station, shooting further and further into the distance. It was Ash.
A loud PING sounded behind George. The red panel had turned green. The Commander must have managed to connect up the air supply.
“George, switch on the pumps!” called Parker.
George entered a code into the panel in front of him. There was a sharp thump, and from the machinery in the walls came an unsteady throbbing sound.
At that moment, Commander Ferguson collided with the airlock window. He thumped against it with a heavily gloved hand. Parker closed the outer door and then opened the inner one to let the Commander in. He tumbled forward, clutching at his space helmet. Josh and Amira helped him to remove it.
“Ash’s backpack blew,” he gasped. “I saw a flash.”
“But the packs on those suits are MegaZone Premium-A,” said Parker. “They’re normally very reliable.”
“Well, that one wasn’t!” snapped the Commander. “Another of my crew gone!”
Parker was clearly upset. The Commander, on the other hand, seemed to be lost in thought.
George was struck by another of those icy feelings of fear. He quickly turned to Josh and Amira and ushered them into a corner of the room.
“I just thought of something, guys. I know we were wondering about whether Dwayne was the saboteur, but what if we’re wrong? What if the saboteur was Commander Ferguson himself?”
“What?” said the others together.
“Think about it – Ash had just gathered vital DNA evidence, which would help reveal the identity of the person who’d caused the explosion. What if that person was the Commander? What if he fought with Ash, outside the station, when they were both out of sight and cut off from all communication? What if he’d done something to Ash’s backpack? What if the Commander got rid of Ash in order to get rid of the evidence too?” George blurted out in a hushed voice.
Josh and Amira looked stunned. The idea seemed absurd.
“Why would the Commander want to wreck his own space station?” whispered Amira. She paused. “But then again, as Parker said, those backpacks are very reliable. I’ve read all about the countless tests they go through before they are fit for human use. Isn’t it a strange coincidence that precisely the evidence needed to find the saboteur was in the pocket of the person whose backpack went wrong?”
“Or maybe Ash was the saboteur?” suggested Josh. “Suppose the Commander realised this and arranged an ‘accident’, in order to hide the fact that one of his loyal crew members was a spy?”
George and Amira nodded eagerly.
“What if Ash’s backpack break-down was all a con?” continued Amira. “Could he have secretly set his backpack to shoot him far out into space? What if, at this very moment, he’s linking up with a shuttle somewhere, instead of tumbling to his death?”
They all looked at each other.
Josh said, “Now I don’t have a clue what’s going on.”
Just then, Dwayne appeared around the corner. “Where have you been?” said Amira.
“None of your business.” Dwayne went slightly red.
“Parker,” said Commander Ferguson. “I thought I told you to watch these kids?”
“They were helping me operate the air pumps, sir,” said Parker. “We’re safe. George switched the back-up feed on for me.”
The Commander sniffed and cocked his head to one side. The machinery behind the panel George had operated was still making that strange, unsteady noise.
“Did he now?” said Commander Ferguson. “Parker, why are those pumps sounding like an ancient steam engine?”
“It’s possible they could have been – ” began Parker.
With an almighty cracking sound, the wall beside them suddenly buckled and bulged inwards. The lights in the corridor spluttered and died.
“What’s happening now?” cried Josh. “Surely things can’t get any worse?”
