We’ve had a wonderful spring here in Phoenix, Arizona – cool by our standards and it even rained here for the first time in recorded history earlier this month. But now the sun is back and it is beautiful. I can’t say I like every single hot day here, but all in all I like the heat. And I like the sun.
It was rumored, in fact hoped, that the Philae lander might wake up from its slumbers when summer approached. If you recall, the Philae lander is the first ever probe to make a soft landing on a comet, 67P/Churyumov-Gerasimenko, Continue Reading
The Spring Equinox is here 03-20-15 – at least in the Norther Hemisphere of Earth. I’ve always loved that word: Equinox. Continue Reading
The DAWN spacecraft, the one with the awesome Ion Thrusters, that has already performed an historical orbiting maneuver around the asteroid Vesta located in the asteroid belt between Mars and Jupiter, is closing in fast on the largest dwarf planet in the asteroid belt: Ceres.

March 6th is the day DAWN will insert itself into orbit around the weird little world that is Ceres – the closer we get, the weirder it looks. Continue Reading
Bullet Cluster: Searching for Primordial Antimatter
Yesterday’s reblog of The Science Geek (thesciencegeek.org – bookmark this one!) blog on dark matter, the weird stuff posited to exist otherwise galaxies don’t make sense, and if galaxies don’t make sense, we don’t exist, but we exist so galaxies make sense but they wouldn’t make sense if it weren’t for dark matter…or if it weren’t for something we haven’t considered yet; because there just isn’t enough stuff (matter) in the universe to explain how galaxies actually hold themselves together.

I’ve been thinking a lot about where Earth’s oceans came from ever since we landed a probe on a comet, comet CG 67P.
It has been conjectured that comets colliding with early Earth provided the water for the oceans. Continue Reading
Regular readers know I am interested in humanity developing underwater cities as soon as possible as potential party-spots for owners of personal submarines – and I am hopeful as a late-middle-aged dude Continue Reading
