She had some horses (Part I)

October 4, 2013

 

I traveled to Denver for the 45th Division for Planetary Sciences conference in October, conveniently located three hours east of a dear friend of my mother. I drove west from the airport as the sun set and the haze around Denver gathered, darkening from a dusty rose to grey to black.  I went over two mountain passes over 10,000 feet tall, feeling no ill effects as I adjusted to the altitude.  Around the tunnels of Glenwood Canyon it began to rain, far better than snow for driving, but still exciting as the Jeep hydroplaned and lost traction on the highway.  I continued onward and wound up in the tiny town of Silt, 97 miles from the Utah border with Colorado.

Boat and Beach Camping on Tomales Bay, 2013

August 17-18, 2013

Arriving at a beach on Tomales Bay by boat and spending the night must go back to the time of the Miwok.  Inverness Yacht Club members have sailed, motored, paddled, and rowed to Kilkenny or Marshall or Heart’s Desire beaches for overnights for so long that it’s a hallowed tradition.

How planetary radar works at Arecibo Observatory

We know Arecibo Observatory for its 305-meter (1000-foot) diameter telescope and its appearances in Goldeneye and Contact.  Aside from battling Bond villains and driving red diesel Jeeps around the telescope (grousing at the site director about the funding status of projects is optional), several hundred hours a year of telescope time at Arecibo go toward radar studies of asteroids.  Tasked to “find asteroids before they find us”, a group of us four planetary radar astronomers at Arecibo (as well as collaborators and colleagues at institutions outside of Puerto Rico) observes asteroids for NASA’s Near-Earth Object Observation program. We study the orbits and surface properties of our rowdy neighbors, near-Earth asteroids.

William E. Gordon telescopeHow do we transmit and receive radio waves using the klystrons and radio receivers at the observatory, and how do we turn these into images of asteroids?  Read more on my guest post at the Planetary Society on how planetary radar at Arecibo Observatory works.

Leaving Tokyo: vegetables, electronics, kimono

May 24, 2012

My last night in Tokyo I wound up at dinner with Yuka, Yuki, Yumi, and Salvador (spot the outlier) at my favorite restaurant that Yuki found: 野菜の王様, King of Vegetables, in Hibiya.  We’d visited the other location in January, and I was so excited to see vegetables that we went again.

Kappabashi, Kitchen Town (合羽橋)

May 24, 2012

 

My last day in Tokyo dawned hot and dry.  I thanked my generous host Hitomi profusely and headed out for some errands.  I stashed my bags in a coin locker at a central station and headed out for Kappabashi, known as “Kitchen Town” for its profusion of shops for restaurants and kitchens.  I was on a mission for my friend Andy to find him a knife.
