Fisher was one of the men in the room who
“We’ll discuss that part of the mission more later in a breakout session, Dr. Fisher. If that is it, we’ll continue?”
“Sure.” Dr. Fisher sat back down, his forehead furrowed in thought.
“Let’s see, where was I?” Roger said as he turned back to the screen and read through the chart to himself. “Oh yeah, our launch window is approximately three weeks in duration over the last three weeks of August with at least a daily twenty-seven minute launch window. So, we’re bound to be able to hit one of them.” Roger clicked the slide laser pointer button and waved the laser spot over several different trajectory maps showing the different launch dates, times, and trip-times per trajectory. Twenty-one different trajectories curved out from an elliptical Earth orbit and curved directly into Mars’ heliocentric orbital path.
“Another thing to remember here, folks, is that launch is a whole heck of a lot more than just lift-off. I’ve taken the liberty to summarize these steps from the SMAD and various previous mission timelines. You’ll find the steps on the next page of the briefing. Launch team, I want you to start breaking them down and populating the steps with more detail.”
“Uh, Roger, I hate to interrupt again.” John Fisher stood up, again. “But four upper stages on a Delta IV Heavy hasn’t ever been done either. I mean, granted I work for LockMart and I know more about the Atlas systems, but they’re very similar. I just don’t know. And you’re showing one of the stages here consisting of three connected and even modified kick motors. How do you think we can pull that off in less than five months? I’m not even thinking design process, bad as that’s going to be, I’m thinking
“John, we’ll do it because we have to,” Roger replied seriously. “This isn’t something that we’re doing for fun or because of science that we can let overrun the budget and slip in schedule. There is literally something dramatically changing Mars and what if, just what if, Earth is next? I want to get that point across as sincerely as I possibly can. If this is the beginnings of an alien contact, onslaught, or whatever, we need to know and we need to know it as soon as humanly possible. Sooner.”
“We can do it, potentially, but only with dispersed production and every production facility on triple shift,” Fisher said, nodding in understanding. “These modifications alone might cost fifty to a hundred million dollars. Do we have that kind of budget?”
“Yes,” was all Roger said. Despite his little pep talk it was apparent that many of them hadn’t grasped the magnitude of the problem.
“Let me make this clear,” Roger said, taking a deep breath. “We have the budget. We have the backing. We have
He paused for a minute for the auditorium to settle, then he continued with the briefing.
“Okay, cruise phase of the mission begins once Percival is in a safe and stable configuration after the control maneuvers at the end of the launch sequence. The best we’ve come up with thus far for transit time from Earth to Mars is about four to five months — feel free to discuss with Dr. Powell transit time optimization if you wish. The cruise trajectory will deliver the spacecraft to Mars on a southern approach trajectory where we’ll begin taking reconnaissance data. In fact, our plan is to passively collect data for the entire trip. Who knows, it might be useful. We also suggest one active sensor, which we’ll discuss in a minute.
