With any luck, it all happens tomorrow!! Perseverance and its little stowaway helicopter, Ingenuity, land at Jezero Crater, on the surface of Mars! I know a lot of people are discussing this right now, but after my post a week or so ago discussing the orbital mechanics of a Mars mission, and why launch windows…Read more Seven Minutes of Terror

Interplanetary Superhighway (Math, Geometry, and Mars Missions)
Let's say you've got nothing else going on, and you decide to launch a mission to Mars, as you do. Technically, assuming you had the rocket and the launch pad and the range clearance, the time and money, etc, you could do that tomorrow some time. BUT, this is a little like Steven Wright's assertion…Read more Interplanetary Superhighway (Math, Geometry, and Mars Missions)
Mars and the Moon
This morning, the Moon passed in front of the planet Mars. My view of the event from the east coast of the US was entirely daylight, and I wasn't sure I'd be able to resolve anything. I was up around 6:30am, and the sky was mostly clear. I stepped out on the back deck and…Read more Mars and the Moon
Watch the Moon Block Mars – Feb 18, 2020
I've been meaning to write about this for a while now, but things keep me busy, as they do, and now it's almost too late, because this event happens TOMORROW AT DAWN!! Tomorrow, the Moon will slide directly between Earth and the planet Mars, causing an eclipse, of sorts. This type of event is called…Read more Watch the Moon Block Mars – Feb 18, 2020
Mars and Venus
I've been trying all week to get this written - and by using this title I don't mean to raise any men vs. women / war vs. love discussions. Not even a suggestion that the two stereotypes are reversed (Mars is a desert, but perhaps still harbors life? Venus is more of the raging acid-hot…Read more Mars and Venus
The Moon, Mars, a Comet, and Maybe a Fireball (Astronomy: Week of 7/22/18)
Wow, there's a lot of cool stuff going on in the night sky this week. I can't wait til this pattern of East Coast thunderstorms lets me see it! Let me give a quick rundown, in the order of my own particular interest and excitement. Your mileage may vary. Mars at Opposition Mars is back,…Read more The Moon, Mars, a Comet, and Maybe a Fireball (Astronomy: Week of 7/22/18)
Ah… Spring, and Stuff (Astronomy: Week of 4/1/18)
As I write this, on 3/31/18, a Blue Moon is rising on the night before Easter Sunday. By convention (and agreement per the Council of Nicaea in the year 325), Easter occurs on the first Sunday after the first full moon that occurs after the Vernal Equinox - one of the few remaining holidays that…Read more Ah… Spring, and Stuff (Astronomy: Week of 4/1/18)
Spring Planets! (Astronomy: Week of 3/18/18)
I am writing this on St. Patrick's Day. Erin Go Bragh! And I'm casting a glance fairly frequently out the window these days, looking for green. Spring is coming - the vernal equinox actually occurs on the 20th this year (Tuesday) - just after noon (12:45pm EDT). Often confused with "the first day of Spring",…Read more Spring Planets!
