“Good evening, and welcome to the Watney and Company Report. I’m Cathy Warner, speaking to you live from Johnson Space Center in Houston.”

Venkat sat a little uncomfortably in a chair just off-camera from Cathy, who spoke to the camera with her usual professional tones. Annie had not so much pulled strings as hauled hard on anchor chains to get the CNN crew on-site in less than twelve hours. Cathy had won the prize not just because CNN had the only hour-long show, five days a week, dedicated solely to Mars, but because CNN was the most likely news organization to give NASA a fair shake.

Which was good, because the main job of the day for every NASA manager was to sell a mountain of hooey to the American public, and that sales job required all the sympathetic outlets NASA could find.

“Today we finally learned why Rich Purnell, an ordinary worker in JSC’s Astrodynamics division, is so important to the lives and future of the castaways on Mars,” Cathy continued. “With the cryptic declaration that Rich Purnell is ‘a steely-eyed missile man’, the crew of Hermes executed a prolonged engine burn that eliminates any possibility of returning to Earth as planned two months from now.

“Instead Hermes will slingshot around Earth, picking up additional speed for a tight pass around the sun that will send it back to Mars, arriving there on Ares III Sol 551. If all goes well, this will allow the castaways to escape Mars almost exactly one year from today- almost eight months ahead of the previously scheduled Ares 3B mission.”

As Venkat sat, audio of Teddy’s speech earlier that afternoon played in his ear, as the video of that speech was spliced into the live video feed from the improvised studio in one of JSC’s many conference rooms.

“Rich Purnell was the worker most involved in exploring the ‘lifeboat’ option for using the alien ship and other parts from the Ares III landing site to escape Mars in case of dire emergency,” Teddy said. “He also plotted the orbital paths for the Sleipnir missions, and in the process he realized that Hermes could be diverted onto a path that would give it a flyby of Mars before returning safely to Earth again. This path would rescue Mark Watney and the shipwrecked aliens far earlier than any prior rescue plan.

“But the Hermes flyby, though ingenious, is the least difficult part of the plan. Being a responsible NASA staffer, Rich took a leave of absence to work on the problem in private, exploring the viability of modifying the Ares IV MAV so that it can escape Martian gravity for a rendezvous with Hermes, calculating required supply loads for Hermes and the rescued astronauts, and even consulting the alien science officer on Mars about possible use of their experimental Sparkle Drive to bring Hermes and all its crew back to Earth mere days after its Mars flyby.

“After the failure of Sleipnir 1 and the abort to orbit of Sleipnir 3, Rich came to us with his proposal. His proposal, of course, was full of risks- risks to the castaways and to the Hermes crew- and we had to evaluate in detail the level of risk compared to the risk of eight more months on Mars for Watney and his guests. Not wanting to raise hopes prematurely, we kept these evaluations secret until we could be certain of the decision.

“The final decision came late yesterday afternoon, after the Chinese national space agency contacted me directly to offer the use of the booster built for the Tai Yang Shen solar observatory. With this booster and the SpaceX BFR originally slated to refuel Sleipnir 3, we could guarantee sufficient food supplies to Hermes for the entire flight, even if the Sparkle Drive fails to bring Hermes home ahead of schedule.”

Venkat heard an unfamiliar voice- some reporter or other- break in to ask, “Wasn’t this experimental drive the reason the aliens were stranded on Mars in the first place?”

“Our contact with one of the shipwrecked aliens, who was a designer of that drive, allows me to state that the flaw that caused them to come here has been identified and eliminated,” Teddy said firmly. “The Drive might not bring them to Earth, but it won’t send them anywhere else. If it fails, Hermes will continue on its predetermined course to Earth, arriving 211 days after rescuing Mark and his friends.”

“You mentioned Tai Yang Shen,” another reporter said. “What is NASA giving the Chinese in exchange for this booster?”

“The Chinese are donating the booster in the name of saving people in need and in the hopes of establishing friendly relations with the first intelligent alien culture we’ve ever encountered,” Teddy said. “However, I am recommending to the Presidential Council on Space and to the House and Senate Subcommittees on Space Exploration that the Chinese space program be offered full access to our alien friends once they’re rescued, out of respect for their expertise and demonstrated willingness to cooperate. Also, we have asked China to submit candidates for taikonauts to join the Ares V and Ares VI expeditions.”

The audio in Venkat’s ear faded out, and the spotlight came up on the table where he and Cathy sat. “For more detail on NASA’s new plan, I’m here at JSC to speak with Ares project director, Dr. Venkat Kapoor. Thank you for letting us be here, Doctor.”

“Always a pleasure, Cathy,” Venkat said.

“My first question, of course, has to be: why is this new plan, which has all the appearance of a Hail Mary pass in the fourth quarter, less risky than waiting eight more months for Ares 3B?” Cathy asked. “Especially in light of the report that the aliens have reinforced their underground farm to secure against cave-ins or blowouts.”

“It’s a choice between known risks and unknown risks,” Venkat said. “We know the risks of modifying the MAV to make it capable of escaping Martian gravity. We know the risks of an extended Hermes mission. But as Sleipnir indicates, and as incidents such as the Sol 6 storm and the Sol 88 Hab blowout make clear, the risks of Mark and his friends remaining on Mars and relying on resupply from Earth are unknowable. We don’t know when the next emergency will arise. If we know about a risk, we can plan for it and take precautions. But we can’t plan for the unpredictable. So, paradoxically, it’s less risky to take a risk.”

“One of these known risks is Hermes’s trajectory, which takes it considerably closer to the sun than any prior manned spacecraft,” Cathy continued. “In fact, NASA in the past has had a hard no-fly rule for any craft, manned or robotic, that might travel closer to the sun than Venus. Why are you ignoring this rule?”

Hermes has multiply redundant heat and radiation mitigation systems,” Venkat said. “It’s required for the on-board reactor that powers the VASIMR ion engines. It also keeps the astronauts safe in case of solar flares during a normal year-long mission. These systems are unique in human space flight, and we designed them to endure the conditions Hermes will encounter on its flight- for precisely contingencies like this.”

That was a fib, and not a small one. Hermes’s flight path would push the safety margins of its magnetic field and hull shielding systems. They’d been designed to specifications that would let it endure the trip, not because NASA had ever imagined even in nightmares allowing the ship get that close to the sun, but because it was simple habit to err on the side of caution when engineering long-term space craft.

“Now, Hermes isn’t going to orbit,” Cathy said.

“That’s correct,” Venkat said. “It’ll be going too fast to brake for orbit. Also, if it orbited, it would lose its free-return trajectory to Earth and basically be stranded until the next Hohmann return window opens.”

“But since it’s a fly-by, that means that Mark Watney and his friends will have exactly one shot to catch them,” Cathy pointed out.

“Also true,” Venkat said. “But the MAV is a robust system, and we’ve checked out the modifications Rich Purnell proposed, and they check out.” Massive lie. The check had been only partial, and the numbers were fuzzy as hell. Purnell’s suggestions hadn’t gone much farther beyond “lose a bit of weight and strap all the pony engines to the first stage.” And Bruce Ng was too busy, first with Sleipnir 4 and now the stripped down cans with thrusters that would be the new Sleipnir 4/5, to do anything about it.

“But what happens if Mark and his friends miss the intercept?”

“The Sparkle Drive will be installed on the MAV,” Venkat said. “It’ll take the place of the five hundred kilograms of rock samples the MAV would carry from a normal Ares mission. If for some reason the MAV misses the rendezvous, they can use the Drive as a backup to either attempt a second rendezvous or limp to Earth. But that’s a contingency we’d prefer to avoid.” And that was the truth. The electrical batteries on the MAV were rated for only seven days of continuous usage. Starlight Glimmer’s report said that it would have taken a day and a half for their ship to go from their home to their Mars-parallel on the Sparkle Drive, when the two worlds were at closest approach. Earth and Mars would be very far apart when the time came to launch, and a direct line back to Earth would bring the lightly shielded MAV far too close to the Sun for anyone’s health.

“So what happens if the rendezvous misses and the Sparkle Drive fails?” Cathy asked.

Rich Purnell had estimated that a working Sparkle Drive was indispensable to a successful rendezvous, unless the MAV became radically lighter somehow. “We’ll spend the coming year doing everything possible to make sure that doesn’t happen,” Venkat evaded smoothly.

“One final question,” Cathy asked. “The timing of this maneuver and announcement, in light of surprising intransigence on the part of certain Congressmen, seems a little convenient for your purposes. Was there any connection between the stand-down at SpaceX and your decision to implement a mission that requires two resupply launches in three weeks’ time?”

“We had faith that Congress would see reason once they were reassured that taxpayer money was being spent in the best way available to ensure the survival of Mark Watney and our alien visitors,” Venkat said. “Our decision to implement the Rich Purnell maneuver was based solely on our judgment of its probable success. Political considerations never entered into it.”

The only reason Venkat didn’t call that the biggest lie of the whole interview was, lying implied that you knew the truth. Someone else might know; he sure didn’t.

Author's Note:

Well, the first missed day. Not on purpose; the hotel internet is acting up.

Expect another chapter tonight sometime.
