He pulled a flip chart away from the wall. The first few sheets were covered with barely comprehensible notes relating to the Apollo 13 astronauts’ abandoned moonwalk checklists: “DOCUMENTED SAMPLE: select sample / place gnomon upsun of sample / sample gnomon [8,5,2] x sun / retrieve sample…” There was a peculiar poetry in the way technical people communicated with each other, he reflected.

On a clean page, he began to scribble. “Let’s see what we have here. How would we do this? What’s the minimum we have to do to get to Mars? I can see three strands of work for the short term. First, we’ll need flight tests of the nuclear rocketry. Second, we’ll have to man-rate the modules of the Mars ship itself, such as a lander. Finally, we’re going to have to get some experience of long-duration missions in space.” He listed the items quickly. “But, whether we go for the Space Shuttle, or for an uprated Saturn program, or both, you’re looking at maybe five years before a new launch system comes on stream. So for the time being we’re going to need to use the Saturn V to get by.” He eyed Agronski. “You know we’ve already announced the suspension of the Saturn V production line.”

“Of course.”

“Now, in addition to the moonshots, we have our Skylab program, which might have needed a couple of Vs. But a couple of months back we redirected the program; we’re going to revert to the wet workshop concept, which can be launched by a Saturn IB. So as of now our remaining Saturn Vs — seven of them built or in production, SA-509 through SA-515 — are dedicated to Apollo Moon missions.”

“How many launches will you need for a Mars program?” Agronski asked.

Michaels blew out his cheeks. “Let’s say, in the next half decade, six Saturn V flights, and perhaps ten Saturn IBs. That should get Skylab well under way, and perhaps take us as far as the first Earth-orbit manned flights of the NERVA, before we get the new launcher. Joe, does that sound reasonable?”

Muldoon grunted. “Yeah. I guess. If you want to cut it to the bone; if you want to run the risk of another Apollo 1 fire.”

“Now, Joe…”

“Six Saturn Vs,” Agronski said. “And there are seven Moon flights left, Apollos 14 through 20.” His lips pulled tight into a thin grin.

So that’s it. Now I know the price, for Mars, for Paine’s job. It was as if Agronski was taking a much-delayed revenge. Agronski had always despised the manned Moon program, opposed it whenever he could. Agronski knows that this is the end of Apollo. Right here and now; right in this room.
