Well, the TDF is long past, and I can hardly remember most of it other than specific moments that are somehow etched into my few remaining brain cells. Work has overtaken everything else in my life for now. Our spacecraft is here and demands our full attention. It arrived from the factory back in early May, and has been the primary focus of LOTS of people since that moment, and will continue to do so until it leaves the earth exactly one month from today (hopefully!).
I'm at work (again) on Sunday. It's rather quiet today as we are a skeleton crew, and as usual the weather SUCKS out here...foggy, windy and cold...yadda yadda yadda. It's like another country out here, or even another planet. There are no booster people here today as far as I can tell, just us for the payload. It's been a very busy week, beginning last Tuesday for me (I had Monday off, as I had just completed 14 straight work-days as of last Sunday). It's an agreement with our customer that we get one day off with pay for every 14 straight days we work. My shifts are still 4am to 4pm (this is the 'day' 'shift, the swingshift is the opposite, and we work round the clock). I need to leave my house by about 2:50am to arrive at the pad (Space Launch Complex 6, or "slick-6" as it's commonly called) by 3:45 for shift turnover. SLC-6 is located about as far as you can go on Vandenberg towards the south, and the speed limit on base during darkness is 35mph (there are LOTS of fog and deer). Last week at this time the spacecraft was still at the big payload processing facility on Vandenberg Northbase (which is about 18 miles closer to home for me). As of last Tuesday morning we began the preparations to move the vehicle (which is safely encased in it's protective 5 meter fairing) to the launch pad. It was lifted and placed on the KAMAG transport, and then bolted into position for the long ride. We (us electrical people) kept an umbilical cable connected to the vehicle the entire time, as we provide constant monitoring of the very expensive payload's health at all times, right up until the moment the MEU (Main Electrical Umbilical) cable detatches as the rocket starts to lift off the pad during launch.
After the vehicle is sucessfully mounted on the transporter vehicle it was then driven outside the payload 'clean-room' facility and connected to the mobile power unit which is part of the transport vehicle (the KAMAG is entirely electric, so it carries it's own giant diesel generator unit everywhere it goes, and also a fuel tank on a tow-behind trailer along with a large air-filter/handling unit to provide perfectly clean chilled air to the payload). The KAMAG has some awesome features...the most amazing is that the deck the spacecraft is mounted to can be tilted, so as the transport is going up or down a hill the deck can be tilted to keep the verticaly mounted spacecraft/fairing assembly as straight up as possible. It also travels at a lowly 2-5mph, and has roughly a 20-25 mile journey to get to it's launch pad. As it crawls along it's constantly surrounded by walking technicians that are all wearing headsets tied into a common channel, so that they can all instantly convey any pertinent info to the driver of the transport so he can make the vital decisions involved with ensuring the payload arrives at it's destination safely. Along with the transport there is a veritable convoy of support vehicles of interested parties that probably stretches a quarter mile. That journey began last Tuesday evening at 6pm on swingshift, and ended about 6am on the following dayshift, with us 'day' crew swapping out with the night shift a few miles from the pad at 4am at a convenient temporary stopping point in the route.
After finally arriving at the pad the spacecraft was lifted WAY high into the tower and finally set down on the top of the booster, which for this launch is a mighty triple core Delta IV heavy. At the moment I believe this booster is the largest/most powerful one in our arsenal. It took all day to get the gigantic vehicle/fairing combination finally set down and mounted, as it's just a HUGE job with lots of potential for disaster (pretty much everything involved is EXTREMELY expensive). This is all done inside the confines of the humongous MST (Mobile Service Tower) here at SLC-6. Actually I don't believe it's technically called an MST at this pad (the rest of the pads on base have an MST, which is typically a single huge 'building' on giant train-type wheels/tracks, where they open doors on one side of the tower and then roll it back away from the rocket which is left standing on it's pad attached to it's UT (Umbilical Tower) ready for launch. The tower here at SLC-6 is actually a 2-part 'clamshell' building if you will, with the UT and rocket in the middle. For launch both halves back away from the rocket in opposite directions, leaving it clear for launch. I think it might technically be called the SAB/MAB, (it's an Air Force pad on an Air Force base...so EVERYTHING has initials and acronyms), and was actually built up for launching space shuttles back in the 1980's (which was cancelled after the Challenger disaster). I'll continue to refer to it as the MST as that's just so much easier.
Here's what the entire assembled rocket with payload looks like in the tower (these are all pictures of the first Heavy from back in 2009, this current one looks exactly the same). For some help in figuring how big this is, if you follow the uppermost gantry (the gray structure that goes from the UT on the left over to the middle rocket, and actually that's the top of the 2nd stage and the bottom of the fairing/payload), that is actually on level 15, which is actually 17 stories up from the ground.
If you are interested in seeing how the heavy booster gets to the pad go to this link:
And if you're really interested, from the link above on the left side near the top there is a column called "The Mission" and below that are links to many photos...these were taken from them, and you can go link after link and follow all thru launch if you are so inclined.
Here's a view looking thru the ocean-side half of the 'MST' right at engine ignition. The UT Gantries are still attached to the rocket/payload, and will be released VERY soon. It's hard to see in this shot but the other side of the MST has backed quite a ways off from the rocket so it isn't damaged by the launch.
This is what it looks like in flight just after it has cleared the UT. In this shot you can clearly see the top of the 2nd stage (in the white above the 2 cones of the outer boosters you see an orange band...this is the top of the 2nd stage and the bottom of the payload/fairing). That fairing is over 6 stories tall, and if you can imagine that entire assembly bolted to a transport vehicle standing straight up as it is for launch, that's how it's moved from the processing facility to the launch pad. Up close the fairing is just HUGE beyond belief, and it's hard to believe we can actually launch it into space!
OK...it's almost quitting time, night shift should be arriving within the hour (woo-HOO!). Then it's the hour drive home where I begin my less than stellar 3 hours of daily family life, and then off to bed around 7:30 to 8:30pm. Tomorrow I get to do it all again. Lather, Rinse, Repeat. That is the story of my life right now. I've just got to hang in there.
Have a great week, and here's hoping you can get out and ride.
And stay frosty!
