TITHONIUM CHASMA: EXCURSION TEAM
Itzak Rosenberg stared at the fireball billowing up from the hopper. It quickly dissipated into the thin Martian atmosphere. He felt as if all the air had been sucked out of his lungs.
“Our supplies,” he said weakly.
“Blown to hell,” Hasdrubal muttered.
“What could have caused it?”
Hasdrubal was already on the comm link. “Base, this is Excursion Three. We got troubles.”
The excursion controller was one of the astronauts. Her slim lace, framed with short dark hair, looked puzzled. “The readouts here look screwy,” she said.
“Damned hopper blew up!” Hasdrubal snapped.
“Blew up?”
“Exploded! There’s nothin’ left out there except some smokin’ wreckage.”
“That’s why the readouts cut off,” said the controller. In the tiny screen on the control panel she looked almost relieved.
“What the hell happened?” Hasdrubal demanded.
“Are you two okay?”
“Yeah. No damage to the camper.”
“None that we can see from inside the cockpit,” Rosenberg corrected.
Hasdrubal shot a glare at him.
“You’ll have to go outside and look your vehicle over for possible damage,” the controller instructed.
Nodding, Hasdrubal muttered, “Guess so.”
“It’s going to be dark in another hour,” said Rosenberg.
The controller nodded back. “Then you’ll have to make your damage inspection right away.”
“Okay, we’ll go out right away. But what the hell happened? Why’d that bird blow up?”
“We’ll have to go over the diagnostics and get back to you on that. Meanwhile, you check out all your systems and do the exterior inspection.”
“Right,” Hasdrubal agreed.
“Keep this link open,” said Rosenberg, with some urgency.
“Will do,” promised the controller.
Rosenberg blurted, “Did the seismometers record the blast?” It was an idiotic question and he knew it but it just popped out of his mouth.
“I’ll ask the monitors,” the controller said. “Call me back when you complete your inspection.”
“Don’t shut down this link,” Rosenberg repeated.
“Right. I’ll keep it open.”
Hasdrubal got up from his seat and headed back toward the airlock. Over his shoulder he called, “C’mon, get into your suit.”
“I’m staying inside,” Rosenberg said, his voice quavering slightly. “I’ll check all our systems while you do a visual inspection outside.”
Hasdrubal stopped at the narrow closet where their nanosuits hung. For a moment he said nothing. Then, “Go faster if the two of us look her over.”
“I. . . I’ll stay inside,” Rosenberg said. “I need to, Sal.” He felt as if he were glued to the cockpit seat. He thought he couldn’t get up even if he wanted to. His legs were too weak to support him. He couldn’t even turn around to look at his partner.
“Okay,” Hasdrubal said, his voice sounding strange, suspicious, almost accusing. “You stay in.”

Jamie was poring over the latest communications from Selene, reports on their underground farms and the amount of electrical power they needed to keep the crops growing. We’ll have to devote a lot of acreage to solar panels, he thought. The maintenance is going to be tough, keeping them clean of dust. Maybe we can automate that, something like windshield wipers. Then he thought about the monstrous dust storms that swept across the planet. He remembered the storm that nearly buried the camper on his first excursion to Tithonium Chasma. With a shake of his head Jamie realized that maintaining a solar-energy farm was going to be a lot more difficult on Mars than on the airless, weatherless Moon.
“Uh, Dr. Waterman?” A soft voice interrupted his musing.
Looking up, Jamie saw that it was Billy Graycloud standing at the entrance to his cubbyhole of an office.
“Come in, Billy,” he said.
The youngster didn’t move. “There’s been an accident.”
“Accident?” Jamie shot up from his chair.
“Nobody hurt,” Graycloud said quickly. “It’s the excursion team, you know, the two guys tracing the old riverbed. Their resupply rocket blew up.”
Jamie could see a small crowd gathered around the entrance to the communications center halfway across the dome.
“They’re okay?” he asked, coming around his makeshift desk.
“Seem to be,” Graycloud replied. Then he added, “So far.”

Hasdrubal was holding a blackened chunk of metal in his hands as he sank his lanky frame into the padded cockpit seat. Rosenberg stared at it.
“Found this in the ground about a meter and a half from our left front wheels.”
“What is it?”
Turning the scorched fragment in his hands, Hasdrubal answered, “What it
was
was a piece of a storage container. I think. Hard to tell.”
“A meter and a half?”
“Give or take a skosh.”
“If it had hit us. . .”
“Would’ve gone through the skin of this bus like an antitank missile.”
Rosenberg shuddered visibly.
“Everything okay in here?” Hasdrubal asked.
“All the systems are on line. No internal damage.”
“Are
you
okay?” Hasdrubal stared at his partner.
Rosenberg took a deep, deliberate breath. “I’m ... rather shaken, you know.”
“I can see that.”
“Control says the hopper’s oxygen line must have been leaking. It touched off the methane. That’s what caused the explosion.”
“They think.”
“That’s what the diagnostics indicate.” Rosenberg felt somewhat better, stronger, as he talked about the impersonal data from the controller’s monitoring systems. Yet he still saw in his mind’s eye that white-hot explosion. We could have been killed, his inner voice kept repeating. We came within a meter and a half of death.
“Dripped oxy on the hot methane pump, prob’ly,” Hasdrubal was saying.
Rosenberg nodded. “Yes, that’s their explanation.”
“How old was that hopper? Some of ‘em date back to the first expeditions, don’t they?”
“I believe so.”
Holding the fragment of debris in one hand, Hasdrubal pointed to the comm screen, which was a blank gray. “Comm link still open?”
“It should be.”
“Okay. I’ll show this to the geniuses back at base. You go back and heat up some dinner.”
Rosenberg hesitated. “Why don’t we start back to the base?”
“Now? It’ll be dark in another few minutes.” The biologist jerked a thumb toward the scenery outside. The pale shrunken sun was almost touching the jagged horizon. The sky was already turning deep violet.
“I know, but. . . we’ll have to head back before we run out of supplies.”
“Tomorrow, after the sun comes up.”
“We can run at night.”
“And run down the fuel cells? No way. We’re not goin’ anyplace until the sun comes up,” Hasdrubal insisted. “That’s final.”
