As a city boy, seeing the center of the Milky Way at night freaks me out. It clearly indicates to me that I’m out of my element: I’m not in Kansas, anymore. Or the city, as it were. The Milky Way was twinkling down on me on June 29 as I assembled my tripod on the unlit causeway overlooking Shelly Bay and the Queen Sound Channel. I was to point a camera toward the terrier improved malemute sounding rocket at NASA’s Wallops Island launch facility in Virginia and hope that this launch attempt would end better than the ten before it.
The Milky Way belied the truth: We earthbound beings would not witness sunrise for over an hour, but a hundred miles above, the Earth curved away sufficiently to allow the sun to shine in space. These conditions would allow NASA scientists to visually observe particle motions in the ionosphere. Said sounding rocket carried a payload of ten canisters of chemical tracers to be dispersed into the upper atmosphere. In combination, the chemicals would form artificial clouds to be lit by the rising sun. Scientists at Wallops and/or Duck, North Carolina would observe and measure the dispersion for their research.
“People look at me with less confusion when I strap into an airplane bound for Orlando than when I’ve strapped into a car headed to Wallops. For the former, the most persistent question is always, “What, no Disney?” Here, the more common reaction was, “Are you insane?”I arrived that day at 4:09 am for a 4:25 am launch. While I’d like to take credit for my perfect timing, the truth is that I did not know if I would even make it. I live nowhere near Wallops Island, and to see this launch would require an all-nighter drive. A social appointment the night before also precluded an early departure where I could get some winks before the big moment.

two new ones.
The way I see it, if you want to win, you have to play the game. I didn’t attempt all ten previous launches, making my own weather judgments before undertaking the 600-mile round trip. But I did try twice prior to this, once on an ill-fated Father’s Day excursion that ended in a father-son tire change and a 150-mile drive home on a donut. And with each decision not to go, I constantly second-guessed myself, sweating bullets until the official scrub decision came.
Most launch windows started a little after 9:00 pm, after sunset. Unfortunately, clouds (real ones) often littered the sky at night, forcing one scrub after another. After a series of bad days, NASA took a pause and then flipped the launch window to the early morning, beginning at 4:25 am. In my experience, though, nighttime launches tend to go more often as planned, and sure enough, the forecast on the morning of June 29 called for clear skies. So I had to go to this one.
The final four and the remnants of
As 4:25 am neared, I became increasingly excited. Having witnessed so many scrubs before – many more scrubs than launches – I tend to tamp down my own anticipation until the last minutes of a countdown. Too many emotional highs followed by scrub-induced roller coaster drops. Thankfully, the terrier-malemute is a two-stage solid rocket. Solid fuel means makes for a simpler rocket than liquid fuel. So, I allowed myself the jitters and emotional excess that may have been reserved before, say, a Falcon 9 launch.
5, 4, 3 -- the rocket was off the ground before “2, 1”! I forgot that there’d be a sound delay from the countdown speakers from their distance. Oops! To make matters worse, the seasoned spectator had led me astray: My camera was pointed in the wrong direction! By the time my lens caught up with its target, the first stage was already falling back to Earth. Unlike the big rockets that normally leave Earth at a rate of 3 Gs, this sounding rocket pulled about 26 Gs. And unlike a space shuttle night launch that you can read a newspaper by, this was a bright match stick that escaped Earth nearly as quickly as my brain could process what was happening. Oh well, forget the video. (Even NASA’s official video could not capture the launch successfully.)

Suddenly, two lobes of colorful, bright light formed in the sky. Some news articles predicted the light spectacle as an “artificial aurora”. Wrong. I’d call them pink flower petals with green watermelon rinds no larger than the moon above your head. As they faded, four more petals came into being in square formation. (This could almost be a scene out of Fantasia if the right score supported it.) A short while after that, the final four. Had I woken in the dead of the night to the sight of these so-called “clouds”, I would have audibly gasped in fear and bewilderment. The petals were surreal and out of place, as though they did not belong to this world. The sight of this evoked vivid memories and the same eerie, ethereal sensation from when I witnessed this same experiment some years ago from New York City. Amazing to think that these figures in the night sky could have such a visual radius.
