The skies above the launch tower were blue, with clouds scattered across the sky. The rocket was on the launch tower and in "ready" mode. Data was pouring out of the flight computer. We could see the ground beneath LV2 in the ATV video broadcast. The four recovery teams were scattered around, waiting to gather up the rocket. It was 3:00pm, and we were ready for launch.

And then, we hypothesize, the ATV broadcast somehow jammed both the 802.11b receiver on the rocket and the 2m radio in the recovery node. We'd never seen this happen before in our days of tests, so we can only assume it was because we were mounted on the launch rail and that was somehow coupling the radios. Or, possibly, somehow the cold temperature was affecting the radios? We don't know yet.

This was the first time an honest-to-goodness technical glitch has scrubbed a launch. We were all feeling a bit let down but not demoralized: the rocket was ready, we were ready, we just hit a problem we never saw before. And in a system with a linux flight computer, a half dozen microcontrollers, two high power radios and a huge ground network, complete with linux server, that's not necessarily surprising. It is hard after all, for the obvious reason ;)

We set up in front of Andrew's house (not the cabin, which has big trees all around it). We set up the Jupiter board and let it acquire 5-6/10 satellites using the 2 x 2 in. active patch antenna. Then we quickly switched it over to the GPS cylindrical patch antenna (CPA) + the unmodified low noise amplifier (LNA). That dropped us down to 4-5/10 satellites, but it did work. So then we reattached the active patch to keep the receiver locked, replaced the LNA on the GPS CPA with the LNA with SAW filters, and tried it again. Nadda, nothing, zippo satellites.

Using Paul's signal analzyer, we saw that the LO's 3rd harmonic is larger than the 2nd harmonic, so it's more of an odd than even function. This means the LO is probably like a square wave - the rise time is too high (the bandwidth of the circuit is certainly too high), it's being overdriven (it might be being clipped into a square wave).

You'll note in the figure the weirdly shaped magenta trace. That's the output of Q2551 which pulls up just fine, but can't pull down at all. It's pull down is a 680 ohm resistor, so it sucks... causing the clipping you can see. The bounce we think may be the parasitic capacitance coupling the emitter to the base.

The rocket was working as planned, with a few exceptions: the aforementioned ATV blackouts, and some freezing in `run_threads`, the software running on the rocket. We think they were due to "operator error" in the sense that we gave it an out-of-sequence command, at which point it locked up. Also, the avionics power system node doesn't report the correct battery current, which is annoying. We know why it's not, but apparently the code to fix the problem hasn't been burned onto the node.

We were late getting setup. The setup went ok. Next time we think we can strap the rocket to the tent pole if we're too lazy to bring the tower. Good news is that there is no evidence of interference from the tower. (Though it's hard to completely rule this out until 100% of our interference problems are solved.) Also good, it looks like the trackmaster is preforming ok and that the 2m has decent range, at least when the pyros aren't charging ;) .

The GPS and pressure altitude disagree to a larger than expected factor. Initially the pressure altitude wasn't being initialized, but once we caught that, the pressure altitude was initialized to 480 feet [146m] based on Andrew's pressure aided GPS. The on-board GPS varied but favored 130m, this is probably a bit further off than they should be with seven satellites. We should try to get the map-altitude of future test sites beforehand.

3. The backup, or "away" ATV system stopped recording for an unknown reason. This meant that we have no real recording of the ATV transmission (again). (We do have the 1st 3 seconds courtesy of a third party who also recorded part of the ATV transmission.)

We set up two pop-up launch control (LC) tents about a mile away from the launch tower. We were that far away because we wanted the receive antennas on the ground to be more than 10 degrees off of the vertical null in the rocket's cylindrical patch antenna pattern. At a simulated apogee of 18,000 ft AGL, a mile gave us about 17 degrees off vertical assuming the rocket was going straight up.

2. We had a remarkably hard time with the signal strength between the LTC and LC. We think this was because the wire parabolic dish antennas (we call them "BBQ grills") didn't work as well over the bumpy terrain (they really should have been higher off the ground) and - perhaps more importantly - they've been really abused over the last few years. We need to replace them with high gain helical antennas (Yagis?) with external covers so we can throw 'em in the back of a pickup and not be worried. When the wireless link finally connected reliably, the LTC BBQ grill was about 10 degrees to the right of where it "should" be pointed as sighted along the pickup arm.

Remarkably, since we were ready to proceed with the launch, we bolted the airframe together, including the prepackaged avionics module, and did a few power up tests according to the [[CurrentCheckList]]: turned on the avionics module, focused the ATV camera lens, and taped it down. Then we slid the aeroshell on and checked the picture again to make sure the ATV prism was on correctly. Brian and Maggie put the nose cone on, slid the motor in, and we were ready to go!

At the launch tower we had a few problems, mostly related to 1) being able to reliably talk to the launch tower, and 2) the polarization of the uplink radio antenna. It turns out that the circularly polarized 2m turnstile antenna that allows us to send emergency 2m commands to the recovery node is horizontally polarized at the horizon. And since the 2m "long wire" antenna on the airframe of the rocket is vertically polarized, the 2m commands never got through. Once the rocket left the ground, we were sure the turnstile antenna would work correctly, but we never realized it would be unusable on the ground. We used the 2m comm radio (which has a vertically polarized J-pole antenna) to arm the rocket on the tower and everything worked as expected).

At this point we had several instances of human error. First, Jamey forgot to uncomment a line in our `prepare-for-flight` shells script, which made the GPS never give a "sane" value because the FC thought it was supposed to be in Portland, not Brothers. After about 5 minutes waiting for the GPS, we looked into it, fixed the error, and restarted the launch sequence. Not to be outdone, Andrew proudly one-upped Jamey when, with 7 minutes left to go in the hour-long high-altitude window, Andrew tried to type in the "arm rocket" DTMF command over the uplink radio and his fingers instead dialed the "emergency shutdown" command... which, of course, _instantly shutdown the whole frickin' rocket_. **AAARGGGHH**!

What happened next is unclear, but for whatever reason, the nose cone did not come off the airframe. This meant that no parachute ever deployed... and thus after apogee, LV2 keeled over and started descending ballistically. We received telemetry all the way to approximately 300 m above the ground, just a fraction of a second before impact, which gave us the GPS coordinates of the impact site. Prior to impact the rocket was still accelerating. The final velocity at impact was more than 560 mph.
