David Mathre Photography

Welcome to my Images of the Day Photo blog. My goal is to post images from each day of the year going back to 2006 when I got my first DSLR camera. Images I post on Google+ are also forwarded to this Photo blog. I am a retired chemist that worked nearly thirty years in the Pharmaceutical industry. I took my first DSLR camera on a road trip across the United States, and became hooked, with my new passion becoming a photographer. I now spend all my time traveling and taking pictures. Since then I have visited over 50 countries, many on Semester at Sea voyages. My photographic interests include travel, the natural world, landscapes, and photographic techniques. I always want to learn something new and the only way to become better is to learn from mistakes.

NASA ATREX Mission. Early Spring, Early Morning Sky Lit Up By Five NASA Sounding Rockets.

Early this morning NASA launched five sounding rockets from Wallops Island, Virginia over seven minutes to study the jet stream in the upper atmosphere at the edge of space. Once the rockets reached the thermosphere they were set to release trimethyaluminum that would react to create a cloud of aluminum oxide. This mission has been canceled several times waiting for clear skies from New Jersey to South Carolina. I set up a Nikon D3x camera with a 14-24 mm f/2.8 wide angle lens and pointed it south east to capture an image every minute starting just after midnight to see if I could to catch something from the mission. The rockets were launched starting just before 5 AM (EDT).

The following is a composite of 40 images combined using startrails showing the release from all 5 rockets. You see the star trails, a couple of jet trails, all five of the ATREX rocket cloud releases and as a bonus a meteor trail.

I also created a time lapsed-video of the launch.
