AeroPAC's late-summer launch meet each year at Nevada's Black Rock Desert is called XPRS, which stands for eXtreme Performance Rocket Ships.

img_2790.jpg - 2004:09:25 16:16:25Multiple parachutes in the sky indicates the ARLISS rocket has ejected the student payloads and all their parachutes have deployed. Now it's up to the students' projects to perform their research.


img_2791.jpg - 2004:09:25 16:17:31A big red-orange rocket lifts off from the 500-foot row of launch pads.


img_2792.jpg - 2004:09:25 16:17:33The red-orange rocket makes a nice straight climb.

img_2795.jpg - 2004:09:25 16:26:57When the Launch Control Officer (LCO) opens the range, there are quickly a lot of people out there setting up rockets on launch pads. Everyone out there has permission from the LCO to enter the range.


img_2796.jpg - 2004:09:25 16:30:23Mike Dennis from Seattle (sitting in chair) describes his cluster engined rocket "Flower Power" to others who asked about it. It got its name because his mother thought it looked like a flower pot, and made the remark while he was looking for a name for it.


img_2797.jpg - 2004:09:25 16:52:26This rocket has a 50's retro theme. But it also flies (and even passes RSO inspection.)


img_2798.jpg - 2004:09:25 18:00:24A launch from the 200-foot row of pads.


img_2799.jpg - 2004:09:25 18:01:55This one was on the 100-foot row of pads. It was way too fast for me to get the picture. I posted the picture anyway to emphasize how difficult these are to catch, and what pictures people are often left with as they try to photograph high-power rockets.


img_2800.jpg - 2004:09:25 20:43:18A streak from a rocket at Saturday's night launch.


img_2801.jpg - 2004:09:25 20:44:22A night launch streak, with the moonlit Calico Range mountains in the background. The lights to the right are other rockets on their launch pads - every rocket at the night launch is required to carry lighting.


img_2802.jpg - 2004:09:25 20:45:30These dual streaks indicate two rockets were launched together in what we call a "drag race".


img_2803.jpg - 2004:09:25 20:49:45This is an interesting photographic effect. The shutter didn't open until the rocket was already in flight. So you only see a streak from where the light of the flame got into the camera. That's why some of the bottom of the smoke trail is not accompanied by a light streak.


img_2804.jpg - 2004:09:25 20:51:11A 15-second exposure in the dark shows rockets on the pads and the Black Rock Range mountains in the background. Those of us standing there could not see these distant mountains in the dark.


img_2805.jpg - 2004:09:25 20:51:37This trail shows the rocket had somewhat of an uneven burn rate, as evidenced by the bright spots in the trail. But it moved so fast that no one watching would have noticed.


img_2806.jpg - 2004:09:25 20:52:21This rocket used a motor with a red-colored flame, which has a brilliant effect on a night flight.


img_2807.jpg - 2004:09:25 20:53:26This was another one where I started taking the picture a bit late. The rocket was already in flight. The camera was in auto mode so it kept the shutter open for 4 seconds until it was satisfied with some of the moonlight it collected.


img_2808.jpg - 2004:09:25 20:54:33A red flame from a rocket makes the streak in the picture. It also illuminated the other launch pads around it. The mountains in the background were illuminated by moonlight. And with a 20-second exposure, this was also able to pull in some stars in the sky.


img_2809.jpg - 2004:09:25 20:55:20This is similar to the previous picture since the next rocket also had a red flame. This view has a little better illumination of the mountains in the background.


img_2810.jpg - 2004:09:25 21:07:31This rocket launched at the end of a 13-second exposure. So the picture captured the liftoff, along with moonlit mountains and a starry sky.


img_2811.jpg - 2004:09:25 21:07:49A rocket is launched at the end of a 15-second exposure. The entire row of pads 11-20 is visible in the moonlight.


img_2812.jpg - 2004:09:25 21:13:15Moonlit launch pads and a starry sky.


img_2813.jpg - 2004:09:25 21:13:40A "burn bag" disposes of excess propellant which can't be used in a motor.


img_2814.jpg - 2004:09:25 21:13:43A "burn bag" disposes of excess propellant which can't be used in a motor.


img_2815.jpg - 2004:09:25 21:13:49A "burn bag" disposes of excess propellant which can't be used in a motor.


img_2816.jpg - 2004:09:25 21:14:00A "burn bag" disposes of excess propellant which can't be used in a motor.


img_2817.jpg - 2004:09:25 21:15:05This 15-second exposure captured a rocket streak, moonlit mountains, starry sky and lights from camp sites 1/4 mile away on the west end of the flight line.


img_2818.jpg - 2004:09:25 21:15:39This 13-second exposure includes the rocket streak, moonlit mountains, starry sky and camp site lights.


img_2819.jpg - 2004:09:25 21:16:15A very nice rocket streak. The 15-second exposure also got the mountains and stars as in previous ones. This one also has a light streak which looks at first like it's between two of the camp sites. But that's actually someone a few hundred feet away, carrying a flashlight as they walk back to the flight line after recovering their rocket. It's as far as they travelled during the 15 seconds of the exposure.


img_2820.jpg - 2004:09:25 21:16:44This rocket streak tells a tale of an unstable flight and nose-first impact in the ground. Oh well, it made a nice picture. I hope the owner was able to repair the rocket...


img_2821.jpg - 2004:09:25 21:17:23A moonlit view of the launch pads. Note that among the stars in the sky, the Big Dipper constellation was also captured in this picture.


img_2822.jpg - 2004:09:25 21:17:52This rocket's streak shows that it never got far off the ground. This kind of out-of-control mode of flight is referred to as a "landshark".


img_2823.jpg - 2004:09:25 21:18:26This was a drag race between two rockets. One went nice and straight. But the other prematurely ejected its parachute, and made several loops as the motor powered around the parachute a few times.


img_2824.jpg - 2004:09:25 21:19:05A red streak from a very nice night launch.


img_2825.jpg - 2004:09:25 21:21:41A 15-second exposure with a moonlit view of pads 1-10.


img_2826.jpg - 2004:09:25 21:22:27Yes, it actually is night time. This is a shorter 2.5-second exposure looking eastward at lights of camp sites along the flight line.


img_2827.jpg - 2004:09:25 21:23:13And looking the other direction, a 15-second exposure of the camps along the flight line to the west. The flight line extends about 1/4 mile each direction from the center area where the launch pads are.


img_2828.jpg - 2004:09:25 21:26:54A white streak from a nice night launch.
