A GPS radio tracker is tucked away...

in the payload bay of my high power model rockets that allows for accurate flight telemetry in real time, and also assists in locating the rocket after touchdown by transmitting its location. Today’s first test flight with the device went exceptionally well and provided a wealth of interesting flight data.

The Featherweight GPS radio tracker mounted on a sled inside the payload bay. A small LiPo battery is secured beneath the circuit board and will not budge under high G forces at liftoff.

Distance between launch and touchdown points is about 100 yards/meters.

The blink of a hummingbird's eye...

caught in a pair of images, capturing the moment when the nictitating membrane extends across the eye.

The opaque nictitating membrane extended across the eye, for about 1/60th of a second.

A long and windy pilgrimage...

to another remote petroglyph panel occurred yesterday, with seven good friends of Rory Tyler hiking eight miles with his remains, dispersing them at this site where he had his epiphany in rock art interpretation.

Longtime friend of Rory’s, BH explains some of the symbols and their interpretations at the panel.

The first hummingbirds...

arrived yesterday and they’re already zooming the feeders. This one is taking a rest after doing the aerial sexy dance for a while, displaying for a female at one of the feeders.

The greening of Castle Valley...

is occurring right now, with more wildflowers showing off their colors, despite the low soil moisture.

Munching on a locust seed pod...

out in the open, this squirrel is clearly mocking me. This is Number Four, having deported three others so far this season to other locations during the ongoing varmint war. They’re very cute but they can be very destructive.

FOLLOWING DAY UPDATE: Number Four is going for a ride. Couldn’t resist the grapes and peanut butter in the live trap.
