Visiting Space Shuttle Discovery (Steven F. Udvar-Hazy Center, Smithsonian National Air and Space Museum)

I left for Los Angeles and my encounter with Endeavour just two days after returning from a visit to the Smithsonian’s Steven F. Udvar-Hazy Center in Chantilly, Virginia. The highlight of the Smithsonian visit was the Space Shuttle Discovery, of course, but after spending three days with Endeavour, I was a little hesitant to go back and look at my photos from my day at the museum. I was worried that the experience, even though it was so recent, wouldn’t hold up to the weekend following Endeavour. Of course, it doesn’t in many ways, but in others, seeing Discovery was also a great experience.

Endeavour’s landing gear was retracted during its move to the California Science Center, of course. I didn’t really think about it at the time, but when I started sorting through my Smithsonian photos, I realized how different the undersides of the two spacecrafts appeared, one staged for landing, the other staged for transport. The experience of scale was quite different, too. On the streets of L.A., Endeavour seemed like a behemoth, lumbering down the center lane. At Udvar-Hazy, Discovery seems quite small, although not as small as the Mercury capsule perched off to the side.

Otherwise, the real lesson I learned by comparing the two sets of photos: it’s vastly easier to figure out exposure and white balance when I’m outdoors in persistent lighting/weather conditions. Museum lighting continues to be a challenge for me. Most of my problems could be solved with a tripod, but white balance is always difficult in a creatively lit museum. It’s a good thing I’m not being paid for this.

Threaded through the partisan bickering during the debates on twitter last night was a string of tweets discussing ESO’s discovery of a planet in the Alpha Centauri system.[1] According to ESO’s press release, the planet was detected through the observation of “wobbles” in Alpha Centauri B’s path of motion. Astronomers speculated that the gravitational pull of an orbiting body was generating the irregularities. Putting the HARPS instrument on the 3.6-metre telescope at the La Silla Observatory to work on the problem, they discovered a planet with an orbital period of 3.2 days. The twitter is excited because Alpha Centauri B is a lot like our Sun and the newly discovered planet has the same mass as Earth—the theory being that our planetary twin has been discovered orbiting the star closest to our solar system. I’m not too worked up about the twinning possibilities, but I do think it’s cool that HARPS is doing exactly what it was supposed to do: find new planets.

In related news, I was intrigued by NASA’s response to ESO’s announcement. It’s as if they’re taking the discovery of the new planet a bit personally. Their press release, ostensibly a statement of congratulations to ESO on its accomplishment, reads more like an attempt to stake a claim on exoplanets of the universe. “We, too, have exoplanet finding capabilities! We have Hubble! We have Kepler! We have the James Webb Space Telescope!”

Endeavour On the Move

Here’s just a bit to let you know how well it’s all going out here in L.A. That’s a close-up of Endeavour’s flank as she (it?) moves out of temporary holding in the parking lot of Bed, Bath & Beyond at Manchester near LAX. That move occupied my afternoon. My early morning hours… Well, my early morning hours were spent getting as close to Endeavour as possible (or as allowed by the LAPD). Here’s what I saw when I looked up at about 4:30 a.m.

More soon—must get some sleep before the next stage of the move!
