As the sun sets on a wonderful set of insect photos from the Wild…
I thought I should start with a transition photo, on a photosynthetic bug bed, to a new photo theme – rockets:
Many insects have served as brave cosmonauts – flying as a somewhat unwilling payload in Estes rockets. The National Association of Rocketry has rules against living payloads, but they make an exception for invertebrates. (I think the intent of the rule was to prevent kids from flying their sister’s pet, but to allow for some curious exploration.)
The Quark is the smallest rocket I have built, with rear-swept fins to avoid nose weight and light enough to tumble back without parachute. It takes half-A-size motors.
If you have participated in some of the 500 million Estes rocket launches that have taken place over the years, you may recall that each letter grade of a motor is a rough doubling of total impulse (B is 2xA, C is 2xB and so on).
So, on the other end of the spectrum, the home brew Q-motor in Wedge’s Nike is about 2^17 larger than the Quark ½-A motor. That’s over 100,000 Quarks going at once. 4x the impulse of a cruise missile booster. It’s a powerful subwoofer roar to witness… as 437 lbs roars off the pad going supersonic:
So blog topics can include extreme rocket launches, on-board video, night launches, tips on photographing supersonic shreds overhead, how to get started, and the joy of rocket science. What would interest you?
