Forty model rocket launches...

so far this year ties me with SpaceX, where they have launched an equal number of Falcon 9 rockets into orbit, on just the 93rd day of the calendar year.

The Semroc Arcas model rocket soared to 507 feet (155 m) on a C6-5 engine and soft-landed under parachute 20 feet away on a 48 second-long flight on a gorgeous morning in Castle Valley.

Don't believe everything you see these days...

given that AI-driven functionality is being incorporated into nearly all software and apps. My neighbor and riding companion wanted a snap of himself riding across Castle Creek, however, the flow had been diverted leaving a dry channel at the singletrack crossing. Photoshop’s “Generative Fill” function nicely simulated a gently flowing stream where one does not exist. Remarkable.

This solitary muley buck...

is one among more than 50 in a small herd that regularly aggregates behind the house around dusk. They’ll be moving up the valley now that spring has arrived.

Level 1 certification was achieved today...

by successfully launching and recovering the high-power HV Arcas model rocket with an “H” motor to 2,314 feet (705 meters). Here are several images taken at the remote launch site on the Colorado - Utah state line. It’s very good and quite satisfying to set and achieve lofty goals in retirement.

Blast off!

The flight recorder showed that the rocket’s top speed was 391 mph with 16.1 G peak acceleration for a flight lasting 146 seconds.

In memory of Rory Tyler...

and the many experiences we shared together in canyon country, I can offer a few images shot while recording his poetry at various locations or examining and debating the symbolic meaning of rock art. I shall indeed miss his good humor and insights in the field, particularly in archeoastronomy.

Nearly back to normal...

snow water content in the high country as a result of several late-winter storms this month. But the valleys remain exceptionally dry, with my gauge recording only 0.15 inches (~4 mm) of precipitation from yesterday’s storm.

Lingering clouds obscure the higher La Sal Mountains where snow is almost certainly still falling this morning.
