Finally, we were back on track for building the warp drive experiment flight demonstrator. We left the setup in the NASA MSFC facility with hopes that we would soon be building a very big Casimir effect energy collector.
All of this time I had been giving Tabitha and Al the possible spacecraft requirements and general dimensions. The two of them began solid model simulations and finite element analysis of the concept vehicle. They also contracted out a lot of the work to some local shops.
The architecture of the spacecraft started out as empty boxes on the whiteboard with names of spacecraft components written in them. Then we expanded each box and filled it with larger boxes. It turns out that Tabitha is a super genius with systems integration and solid modeling for spacecraft design. Al is pretty sharp, himself. The two of them together were amazing and accomplished some of the best spacecraft engineering I had ever seen.
The problem wasn't the design or complexity, but the sheer size. The size of the damn thing kept growing. Sometime in November we decided that the only way to get the thing in orbit would be to either build it there or take it up on the Shuttle. Expendable Launch Vehicles (ELVs) were just not big enough. Tabitha called me after they figured this out.
"How much do you weigh?" she asked.
"Why?"
"So I can account for it in the mass budget for the mission."
"Hunh?" was the wittiest thing I could think of.
"Well, somebody has to deploy this damn thing. It ought to be the guy that invented it? Besides, there is budget now for a payload specialist." I could hear her smiling through the phone.
I tried and tried, I really came close, but in the end, I failed to shit a gold brick, which I said I would do if I ever made it to be an astronaut. It had never dawned on me that somebody might have to deploy this thing from the Space Shuttle. I always had envisioned some sort of ELV. To tell the truth, I expected to be about ninety by the time we ever figured out how to do the experiment, for sure not going on forty-two.
"What about you?" I asked Tabitha.
"Nope. I plan to be flying the Shuttle on NASA's dime," she said. You see, payload specialists aren't NASA employees and a company pays for their training and their ride. Taking me was a smart idea on Tabitha's behalf. Now both Tabitha and I could be there for the test.
"I love you!" I told her.
"I know." She laughed. Solo and Leia thoughts popped in my head. I'm sure she'd planned it that way.
We ended up hiring another subcontractor firm to help us with the spacecraft bus and the systems engineering and integration for the demonstrator. You would absolutely not believe the amount of paperwork required just to get something on board the Space Shuttle. It almost seemed like we would invent a better access to space vehicle before we had the dang thing qualified to fly in the Shuttle. It might have been easier to wait for the second generation reusable launch vehicle (2nd Gen RLV) being constructed via the Shuttle Replacement Initiative. However, that thing was falling behind schedule and over budget. After all, Congress changes its mind on funding for that program on a daily basis. In addition, it would have to be tested for a few years before payloads were put on it. It just wouldn't be ready in time. So, Space Shuttle it had to be.
First, we had to demonstrate that we could completely control the warp field and the energy systems working as one system in the environment chamber at NASA MSFC. That was a scaled experiment. The fact that all of this was now classified slowed down some of the progress due to security, but it sped up the process due to processes that could be sidestepped. Then we constructed the full-scale experiment: not actually warping just powering up to the available power level in the chamber, then down. Even though the power level for the warp field was at fractions of that required to actually drive the warp for an object the size of a spacecraft, the stress on the field coils were still tremendous. We couldn't figure out how with modern materials to support such huge stresses as would be caused by a full-scale warp bubble. A full-up test on the ground was out of the question. Besides, the power supply wasn't complete yet.
Once as much of the full-up tests as possible were complete, we had to start integrating all of these components into a spacecraft. This part was complicated. Everything we used on the spacecraft had to have been spaceflight proven in some fashion or the other down to the last nut, washer, and bolt. This is where I relied on the experience of Huntsville, Alabama. There were a couple of local firms that could do this integration properly and at the right security levels. We ended up choosing the same company that built the lunar rovers forty years ago. The sheer size of this development project had grown to hundreds of people and millions of dollars. My program management skills were being pushed to their limits. I relied heavily on Tabitha.
By the time Thanksgiving rolled around, the scaled tests were almost complete. Rebecca was basically back to her old self again, although she was now four months behind on her black belt quest. The only scar that remained, after the laser treatments, was a hair-thin ring around her left ring finger. The engagement ring that Jim gave her on her birthday (October second), covered that up nicely.
Finally, Rebecca and Sara had started on the actual flight hardware pieces for the energy collector. This was going to take a while. It took them about a day to grow the prototype element, which was a ten-centimeter by ten-centimeter wafer with four hundred layers in it. Each layer is four thousandths of a centimeter thick. The final system will have to be a rectangular solid about three meters by three meters by nine meters. We chose these dimensions so it would fit in the Space Shuttle payload bay, which is about four meters by four meters by eighteen meters. Effectively we're building three cubes three meters on a side and connecting them linearly. At the rate it took us to actually build the microscopic prototype it would have taken about twenty two thousand years to make the three cubes.
'Becca and Sara hooked up with one of Sara's friends who works at a local printed circuit board company. They make tens of thousands of computer motherboards a day. By Christmas they had set up the first automated assembly line process to construct Clemons Dumbbell etched boards. The first few weeks were dismal failures and the assembly line was constantly shutting down or failing in some manner. Worst of all, 'Becca found that the quality of the products they had made didn't meet specs. She had to explain to them the severe catastrophic possibilities of Clemons Dumbbells not built to spec. She told then the horror story of having her finger blown off and embellished it very well. Years of being around a lying scoundrel like me paid off.
Sara worked that company over pretty good until they produced a line of to-spec products. They managed to get a final line output of about eighteen thousand boards a day with about five and a half of a percent quality control. This meant that we had to throw away about a thousand boards a day. That leaves us with seventeen thousand boards in a day. This meant that nearly a half a million boards are just thrown in the recycle bin. We all considered the problem, but just didn't have the manpower or the resources to worry with that little amount of quality control. Each board cost about a dollar to make. So the final cost of the cube would be about eight million dollars plus the half million plus that we have to throw away. It would've taken at least a half million dollars in man-hours to figure out how to reduce the quality error.
