Sondra looked at Uchi. "We'll ask the Committee. I don't think there'll be any real objections. We'll get back to you ASAP."
"Saenger out."
Off that star was black, and the light was so bright on the sunward side that all Saenger's screens had to be filtered down to No. 3.
The sun still appeared as a red giant in the optics, burning brighter than when Saenger docked around it. But Saenger had other eyes that saw in other waves. His neutrino grids saw the round ball of the star and its photosphere, but deep inside it detected a glowing cone, growing larger and more open each day, rooted down inside the atmosphere of the sun. The helium flash was not far away.
Already Plato had revised his figures again. He had little more than seven months before the star blew like a cosmic steam boiler, giving men the first close look at an event they had not seen before.
The star would cover the whole sunward sky, its shell would expand, covering everything for millions of myriameters with the screaming remnants of its atmosphere.
Saenger had no margin of safety.
He did not have time, or the proper materials, or anything.
He was monitoring himself and his worker robots as he moved outward on his reaction engines. He had swung out of the orbit as soon as the Committee had given permission.
His robots moved in and out through the airlocks and the open sides of the ship.
One of them, using a cutting laser, sawed through its leg and went whirling away on a puff of soundless force. These robot were never made to work outside the ship.
If Saenger could have, he would have said the word damn.
"Plato?" ?
"There's not enough material in the ship unless I cannibalize my shielding." » «"
"But that would defeat the whole purpose."

"Well…"
"Now he's using his scoops," said Sondra as she monitored the Snapshot encoding for the day. "What in the hell is going on out there?"
"It's not interfering with the monitoring programs. He's sent out two more remote monitors. And the activity down there is picking up."
"He's backed off on his use of Plato. Way below normal, in fact. Do you think we ought to have him dump his grids now?" she asked;
"You're the boss," said Uchi. "I'd get as much information as we could first. He may find something in those last three minutes we don't know about."
"Has Plato contacted him?" asked Sondra. "Hmmm. Not lately."
"He's cut him loose," she said. "He's on his own." Saenger was fighting now, with every passing moment. The ship was unrecognizable. The revamp Plato suggested changed the ship completely. Spidery arrays went out and out from the skeleton, and among them the robots worked.
Stars shone through frames which had once held thick shielding. Laboratories, quarters, all were emptied and dismantled. The frames themselves were being shaved away with improvised lasers until they were light and thin as bird's bones. The ship was little more than a shell around the solid-state intelligence and the fusion ram.
Saenger was using the magnetic scoops at the moment. He sucked in the loose hydrogen atmosphere which bathed the star system. The giant coils began to hum, and as they did Saenger lost some of his capacity, like a man too long under water. Part of his shielding was to protect him from the effects of the coils, and now that plating was gone. He was taking in hydrogen, compressing it, turning it to liquid hydrogen which would shield him from most of the harmful radiations.
Soon, though, he would remove the plates which shielded him from the growing bath of X-rays, photons and other stellar garbage. He was not sure, as he told Plato, that he could remain for long in that acid shower.
Saenger pulled a sufficient quantity of hydrogen in, turned off the coils. He let two robots carry off another layer of insulation.
Saenger was like a dazed man on a battlefield, too long without rest. And the real war had not even started.
Plato was more nearly right.
Three days before the predicted time, the star entered its supernova scenario.
The Director was down in the Banks, with most of the Committee and other interested spectators. Uchi and Dr. Maxwell sat at their usual places before the Snapshot consoles.
"Really too bad," the Director was saying. "Research project like that scratched; about to lose one of our shipboard SSIs. But it'll give us a good look at what happens when a star dies."
They were scanning Snapshot for full visuals, X-ray, infrared, ultraviolet, radio. This would be the most closely watched star event ever, and they were running it all into Plato's permanent storage section where even he could not erase it.
If he had thought to try.
"How do you want to handle the monitors, Saenger?"
"I'll keep on the innermost probes until they are overtaken, then transfer to the outermost. Then back, and I'll hold as long as I can. Then you ought to have a few minutes on the farthest remote before it goes."
"Good enough. Please monitor readings until the shock wave hits. We'll listen in when we're not too busy."
"Certainly."
"Oops!" someone said. "There is goes."
It's hard to imagine a star shaking itself to pieces, but they saw it up close for the first time, then. One second the star seemed fine, if a little bright, then it darkened and the whole surface lifted like a trampoline top.
This from the closest of the probes, one million eight hundred thousand myriametets out. The limb of the star they were watching grew and grew and filled the screen and…
They were watching the sun expand from the second remote, two million two hundred sixty-eight thousand myriameters away, on the opposite side of the star. The sun filled that screen too, and the screen went blank before the shock front reached it and…
"Shockwave, pulling a little ahead of the gases," said a technician.
"Forty-seven point two seconds to the first. Seven-seven point seven to the second. About a tenth light-speed for the gases," said Uchi.
The information sped from Saenger through Snapshot to Plato. Records, stacks of tape, videoprints, all rolled into the permanent storage units on the Moon. They watched the star kill itself with its own light and heat.
The pickup switched to the furthest probe, orbiting almost two AU from the star. For the first time, they saw the whole sun, and it grew and grew even as they watched. It was immense, the lenses kept filtering down and down and still they could not keep the sensors from burning out. Lenses rotated in to replace others, and the thing covered fully a third of the heavens even this far away.
And it got bigger.
"He's supposed to switch back," said the Director. "Isn't he?"
"Do you think it already hit him?" asked one of the spectators.
"Couldn't," said Uchi. "We haven't gotten his information dump through Snapshot yet."
Then he looked at Sondra.
"He can't hold it on us, can he?"
"No," she said. "It's in the program."
But she bit her nails anyway.
Uchi timed the expansion. "It should have gotten him now! Why didn't he dump? Is he still on?"
Sondra feared to look but she did. Two inputs still through Snapshot. The outer probe and…
They looked at the screen. The supernova appeared as a rolling unfolding bunch of dirty sheets, and the center grew whiter with each ripple shaken loose.
It covered half the screen, then two-thirds, then three quarters.
"The shock must be almost to the probe," said the Director.
"What happened to Saenger?" asked Sondra of Uchi. "Where is he?"
"Look!"
They all did.
The whiteness of the star filled the screen and there was a marbled spot through which the glowing central core could be seen. The star must have lost a tenth its mass. The widening sphere of white-hot gases and debris whipped toward the probe.
And in front of it came something that looked like an old sink stopper.
