313/11:40:00 MSP And now the MEM, the Excursion Module which will be the first ship to land humans on the surface of Mars. We’re going to call it after a famous U.S. Navy ship, which made a prolonged and very successful exploration of the Atlantic and Pacific oceans in the 1870s.

313/11:40:19 CDR Yes.

313/11:40:21 MSP We’re naming our MEM Challenger.

GEORGE C. MARSHALL SPACE CENTER, HUNTSVILLE, ALABAMA

The conference room was almost full, but a chair had been reserved for Udet in the front row. He took his seat and crossed his legs with precise motions.

Gregory Dana was at the lectern, fumbling with his thick spectacles, preparing to speak. Udet had not been surprised when Dana had been selected to chair the investigating panel.

On a large screen behind Dana, an image was projected; it showed the Saturn VB stack a few minutes before launch from Pad 39B at Kennedy. The fat MS-IC first stage gleamed white in the sunlight, with its wide tail fins and the four slim Solid Rocket Boosters clustered around it. It looked like a broken-off piece of some elaborate Moorish temple. The second stage was a squat cylinder atop the MS-IC, bone white, with the silver-gray gumdrop shape of an unmanned boilerplate Apollo capsule at the top.

Umbilicals snaked into the stack from the big, complex launch tower, feeding liquid oxygen and propellant into both the liquid stages: hydrogen for the second stage, and RP-1 — kerosene — for the big first stage. Vapor wreathed the upper levels of the booster, dispersing slowly, and Udet could see the sparkle of ice against metal and insulation.

The sky behind the stack was a gray-blue, and heat haze shimmered about the tower.

Udet felt his heart move at the sight. He had never lost his boyish wonder at the sight of such magnificent devices — these heroic machines — wrought by human hands from the raw materials of the Earth, to be hurled toward the planets.

And, of course, that sense of awe was piqued on this occasion by his foreknowledge of the fate of Booster AS-5B04, just a few seconds later.

Udet glanced around. Joe Muldoon, up on the stage with Dana, was moderating the meeting, and much of NASA’s senior management appeared to be in attendance; there were staff from Marshall and Houston and NASA Headquarters, including aides of Tim Josephson, and a heavy representation from the contractors responsible for the system components under scrutiny today.

The presentation was to be a summary of NASA’s preliminary internal report into the problems encountered during the launch of Saturn VB stack AS-5B04, three months earlier. Depending on the reaction of this audience, and on the NASA hierarchy as a whole to the content of the report, a draft would be finalized and published within the week.
