You know how to tell you’re getting old? If you wake up at 3 a.m., realize a Falcon 9 rocket will be going up in 44 minutes, but don’t reach for the iPhone next to the bed because you’re too tired to watch a livestream of the launch, you might as well check yourself into the old folks home ’cause life is all downhill from there.

In my defense, I did stay up all night to watch SpaceX’s first launch attempt at 04:55 a.m. EDT on May 19, 2012. The launch scrubbed at T-0.5 because of a high combustion pressure reading (faulty check valve) on Engine 5. Lift off didn’t happen and I instantly fell asleep. Because the launch window was only one second long, SpaceX was forced to wait until May 22, 2012 for the next attempt. Remind me never to get involved in an operation that depends on a one-second launch window. That’s insane, really.

Today’s wallpaper shows the successful SpaceX launch from LC-40 on Cape Canaveral Air Force Station at 03:44 EDT yesterday (Tuesday, May 22, 2012). If you’re lucky and don’t need much sleep, you may be able to catch a glimpse of the Dragon capsule orbiting together with the International Space Station. Just pop over to the Heavens Above site, configure it for your current location, and follow the SpaceX/Dragon and ISS links in the “Satellites” category. The site will provide you with everything you need to know for a successful observation of an ISS/Dragon pass over: date, time, altitude-azimuth, and magnitude. We’re setting an alarm for tomorrow’s 03:59:59 EDT pass, when the Dragon capsule and the ISS will be only one degree apart.

ETA: As Danny Sussman (@TheSuss) points out, if the times on Heavens Above seem wrong (the site isn’t recognizing Daylight Saving Time for my current location, for some reason), you can bring up flyover times on the NASA app if you have an iPhone or Android. NASA updated the iPhone version earlier this week. The update stalled out on my phone for a frighteningly long time, but once it went through, all was good and accurate.

Rad Lab & Building 20

16 05 2012

Rad Lab and Building 20 Exhibit, Stata Center, MIT

In addition to trying to wrap up the typical end-of-the-semester tasks last week, I also made a quick trip to MIT (Cambridge, MA). I had a few hours to myself on either side of my meetings and I put those hours to good use by walking as much of campus as possible. Needless to say, MIT sits at the intersection of my primary research foci, architecture and science. Perhaps also needless to say, my first stop was the Stata Center, the most controversial building on campus (still, even though it opened in 2004).

Early dissent over the Stata Center had little to do with the design itself and a lot to do with emotional and intellectual attachment to the building it was slated to replace, Building 20. For the purposes of this site, the most notable thing about Building 20 was the fact that it once housed the Radiation Laboratory funded by the National Defense Research Committee (NDRC). Although MIT’s involvement with military research was always seen as problematic by some (and those sentiments would increase during the Vietnam era), during World War II, Rad Lab became the control center for a global research network centered on applied microwave physics.[1] Most of the radar and microwave communication technologies developed during the war came out of the Rad Lab; the British military developed the rest.

The photos above show the homage to Rad Lab in one of the hallways of the Stata Center. The radar antenna stands on top of a wooden crate that holds a Building 20 time capsule. Kudos to the person who chose this particular antenna as representative of MIT’s research. As the accompanying signage explains, the SCR-615 radar system was “not one of the best” (possibly explaining why there was a spare dish sitting around the MIT Museum). You know you’ve got confidence when your celebratory display highlights not just your research successes, but your research disappointments.

With the end of WWII came the end of Rad Lab, but not Building 20. Research in microwave physics was absorbed into the Research Laboratory of Electronics (RLE), housed in the A wing of the building. The Laboratory for Nuclear Science (LNS) took up another good chunk of the space. The military maintained a presence in Building 20 in the form of ROTC headquarters as well as a few U.S. Navy offices. More famously, the building also became home to MIT’s linguistics department. One wonders how different Noam Chomsky’s ideas about the military and U.S. foreign policy would have been had the department been housed in Kresge Auditorium (probably not THAT much different, but still).

Building 20 is no more, of course. In its place stands the Stata Center, a 3-dimensional wonderland of space designed by Gehry Partners LLP.[2] The controversy comes from the multitude of problems reported by users of the building. MIT eventually sued (and then settled with) Gehry.

I have much to say about the Stata Center, so feel free to contact me if you’re interested in my analysis. My photos of the building are available on flickr, as are my photos of other parts of the MIT campus.

If you’d like to read a warm and fuzzy article about Building 20 and its role in MIT’s campus culture, see “A Last, Loving Look at an MIT Landmark—Building 20,” RLE undercurrents Vol. 9, No. 2 (Fall 1997). [download .pdf].

Gehry and partners don’t really need to invest time and money in their own advertising—trade and academic publications do all their publicity for them.





ATREX

28 03 2012

I really tried to watch the launch(es) of the Anomalous Transit Rocket Experiment (ATREX). On several different occasions, I fired up the Wallops video feed, only to disconnect it a few minutes or a few hours later when the launch was scrubbed once again. In the end, I missed the launch of the five sounding rockets—getting up at 4:00 a.m. doesn’t sound like quite as good of an idea to me now as it did when I was a teenager. So, like the rest of the world, I have to make myself happy with the photos and videos circulating around the Internet. So far, my favorite images come from NASA’s Earth ObservatoryA Barrage of a Launch.





A Tour of the Moon

25 03 2012

 

More video goodness! From NASA’s Goddard Space Flight Center and the Lunar Reconnaissance Orbiter (LRO) comes “A Tour of the Moon.” As described by Goddard Multimedia:

“‘Tour of the Moon’ takes viewers to several interesting locations on the moon. Tour stops included in this breathtaking journey across the moon’s surface are: Orientale Basin, Shackleton crater, South Pole-Aitken Basin, Tycho crater, Aristarchus Plateau, Mare Serenitatis, Compton-Belkovich volcano, Jackson crater and Tsiolkovsky crater. The fully narrated video, as well as clips from each of the stops on the tour, are available to everyone in formats viewable on virtually any device.”

Although there are many fantastic scenes in this video, my favorite is the section showing the close-up views of the Apollo 17 landing site. Sweet.

Online Orrery Screen Capture

How awesome is this online orrery? Embedded in the black background are small grey control switches. You can set the date, display the zodiac, or trace a particular planet on the upper right. The slide on the upper changes the direction and speed of the rotation. I’m particularly enamored with the Tychonian universe option on the lower right and the lunar phase option on the lower left.





Abandoned Observatory, Nizhny Novgorod

Zimenki Radio Astronomy Station, Радиоастрономическая станция «Зименки», Nizhny Novgorod, Russia

Are we still talking about abandoned observatories? If so, I’ve gathered a few links for the Zimenki Radio Astronomy Station in Nizhny Novgorod, Russia. The Zemenki Station was built for Gorki University in 1949,  near the village of Zimenki on the Volga River. Originally, only a single radio telescope was constructed on the station. Eventually, two dishes were erected at the site.[1]  I’m not quite sure when work at Zimenki came to an end. It was functioning in 1964, when Zimenki and Jodrell Bank participated in several communication exercises.[2] According to the Committee on Radio Astronomy, a single dish was operational as recently as 2002. If it’s still working, I can’t find information about it. A visitor to the site in 2010 indicated that there was only one dish on the station, but none of the radio telescopes was in working order. If anyone can direct me to more information (in Russian or English, print or digital), I’d appreciate it.

An Awesome Way to Shovel Snow

20 01 2012

Jet Engine for blowing snow off the (former) 300 foot telescope at the NRAO Green Bank. Photo courtesy NRAO.

I found this photo, which shows an unnamed technician, Clifford Barkely, and Paul Devlin inspecting a jet engine, in NRAO’s facebook photo album. Back in the olden days (okay, before the 1988 collapse of the 300-Foot Telescope), engineers used to set up a jet engine next to the dish to blow it clean it of accumulated snow. I can only imagine the noise—I used to complain about the wind machines in the orchard next to my house when they ran during cold spring nights, and those were powered by car, not jet, engines (you can listen to one here, or you can just imagine a Chevy V-8 parked outside your bedroom window).

Since the 300-Foot Telescope is no more, the snow now accumulates in the dish of its replacement, the Green Bank Telescope (GBT). I’ve never seen it in action, but apparently controllers just tilt the dish past the angle of repose so the snow slides out. Maybe not as awesome as a jet engine blowing snow off the instrument, but I bet it’s still plenty interesting to watch an avalanche clearing a 100-meter dish.

Eyes on the Solar System

2 12 2011
Stellarium screen shot

Screen shot of Stellarium, showing this evening's southern sky

There are a number of useful observing tools online. For instance, today I used Sky and Telescope’s Transit Times of Jupiter’s Great Red Spot to plan this evening’s observation session. I regularly use Stellarium, a free open source virtual planetarium, to look at the night sky. Similarly, I try to look at Heavens Above at some point during the day so I know when to run outside and look for an interesting satellite flyby. I follow the International Space Station on twitter (@twisst); once a day I get a tweet telling me when and where to look to see the ISS flyover. So far today, I’ve used Sky and Telescope’s This Week’s Sky at a Glance, the Red Spot calculator, Stellarium, and two iPhone apps (Moon and Moon Globe, both free). I also used Mars Globe, but just because I was goofing off—I like to know when daylight strikes Gale Crater, for some reason.

And speaking of goofing off, if you’ve got some time on your hands, I’ve got the website for you. Before last Saturday’s Mars Science Laboratory launch, attendees of the MSL NASATweetup had the opportunity to attend a demonstration of Eyes on the Solar System, JPL’s 2D/3D visualization tool. Populated with NASA mission data, Eyes on the Solar System allows the user to soar and leap through the universe in real time (you’re not limited to real time, though). I’ll be honest: the learning curve is a bit steep, but once you get the hang of the controls, you’ll find yourself zooming from planet to planet, satellite to asteroid. You’ll be playing god, commanding the moons of Jupiter to orbit in double time or more. I’ve currently got them moving at approximately 170, 700, 000 miles per hour, which means I’m forcing them to fly across the distance they would normally travel in 1 hour in the space of a second.

The above screen shot (click on the image to enlarge it in a new window) gives you an idea of the user interface. If you look at the bottom center of the screen, you can see that I’ve sped up the speed of the orbits (170, 065, 241 MPH at the moment I took the screen shot). To the right of that speed designation is a button for re-setting the motion to real time.

Above is a screen shot with all the menus open. You can see some of the pre-set tour options in the left-hand fly-up menu. You can zoom in and study the sun, any of the planets, including the dwarfs, asteroids and comets. But maybe the most exciting option is riding along with some of NASA’s spacecraft. You can configure the program to look over the spacecraft’s “shoulder” or use the SPEED + RATE menu to look ahead in the spacecraft’s predicted trajectory. I’m super happy to say that Mars Science Laboratory data is already being folded into Eyes.

The above image shows a view of the spacecraft as it should look on August 4, 2012. To the left of the spacecraft is a small window showing its current location in the solar system (produced by clicking on the crosshairs icon on the left-most fly-up menu). Just a note–if you’re being blinded by a regular flash of light, you’ve probably zoomed in too close to Mars. Now for the cool stuff. Got your 3D glasses ready? We’re going anaglyph. Zoom to a good view of Mars and its satellites, then click on the top bar of the VISUAL CONTROLS menu, to the right of the screen.

Now, click on the “View in 3D” line under PERFORMANCE on the VISUAL CONTROLS menu. Put on your glasses and you’re good to go.

You’ll just have to imagine a room full of space geeks wearing cardboard 3D glasses during our demonstration on Saturday (or you could do a web search, ’cause I’m sure the photo evidence is out there somewhere).

The entrance page to the Eyes site provides links to a video introduction, which I recommend watching before you starting pointing and clicking (trust me, been there, done that, had to start over). The tutorials are even more helpful. Many thanks to the team behind Eyes on the Solar System, especially JPL Visualization Producer, Doug Ellison (@Doug_Ellison@NASA_Eyes), who graciously demonstrated Eyes on the Solar System and Eyes on the Earth for us. And thanks to everyone at NASA and JPL for making the MSL NASATweetup happen. Thanks to you, I learned a ton, met some great people, and finally got to attend a rocket launch.
