WP-DC13 and Cellphones for Soldiers
I recently ordered a WP-DC13 camera housing (above left) so I can bring my SD1000 diving next time I’m in the Philippines. When it arrived, the Amazon box included a little plastic sleeve marked “Cellphones for Soldiers” (above right), an interesting little project started by a pair of teenagers to recycle people’s old cellphones by donating them to military personnel in need of phones to contact loved ones back home. Putting aside questions of war and Iraq, I’m wondering if this doesn’t have security implications — soldiers calling family via prepaid cards in the Middle East?
Note from reading the FAQ that most of the cellphones donated don’t actually go to soldiers since they’re not GSM, and instead are sold to a recycler who pays for prepaid cards to send to the soldiers.
As for the housing, it looks great and fits the camera well, but I still need to take it on two test dives in the bathtub sometime — one “unmanned” safety dive without a camera and one “manned” dive with the camera. Then we’ll see how it works. With photos of me in the tub! Bet you’re looking forward to that, eh?
Kogod Courtyard Opening
Amy and I checked out the grand opening of the new Kogod Courtyard at the Reynolds Center yesterday. We admired the architecture, wandered around the crafts tables, ran into a few friends, watched mimes and magicians, and got a photo with George and Martha Washington:

Caturday!
Once again, you’re seeing this Sunday because I forgot to post it yesterday, but I’m backdating it to Saturday so that no one will know. Ssshh, our secret. Anyway, as of late Pandora’s new favorite hangout spot has gradually moved from right in the doorway to right by the dirty laundry area, where she seems to enjoy the texture of old clothes spilling out of the basket onto the carpet:
The sweatshirt she is nesting in has since been laundered.
Eduardo San Juan and the Lunar Rover: the MOLAB Study
Continuing my inquiry into the legend of Eduardo San Juan and the lunar rover, you’ll remember that I sent an email to historians at NASA and Boeing to ask about him. Mike Wright of the Marshall Space Flight Center History Office emailed back with a very interesting PDF attached: a report and conceptual design for the possible construction of a lunar shelter and roving vehicle, submitted to NASA MSFC in November 1964 by “E.C. San Juan” of Hayes International Corporation. The document is just one of a series of “Apollo Logistics Support Systems” papers submitted by Hayes engineers as part of a NASA MSFC contract to research lunar surface exploration technologies for a project called “MOLAB,” which would later be cancelled.
- Apollo logistics support systems MOLAB studies : lunar shelter/rover conceptual design and evaluation / prepared … by E.C. San Juan. Lunar shelter/rover conceptual design and evaluation (LPI CIRS Library Catalog Entry, PDF format)
- Other MOLAB Studies from Hayes engineers on NTRS
Looking over San Juan’s work, it looks like he was an engineer who knew his way around aerospace concepts and hardware, with lots of math and physics and charts — although sections of the report lapse into pithy exposition of basic concepts in descriptive astronomy and spaceflight which I thought would be common knowledge to anyone receiving this at MSFC. The lunar terrain rover (LTV) is part of a larger proposed “lunar base” package composed of a lander with a two-man shelter/laboratory module (SHELAB), a one-man lunar rover, and a spacesuit-attachable rocket belt.
The SHELAB/LTV concept might appear remarkably prescient, superficially resembling Grumman’s Lunar Module five years before Apollo 11, and Boeing/Delco’s Lunar Rover seven years before Apollo 15. This is better placed in context, however, considering that this comes about two years after MSFC accepted the Grumman LM contract, and knowing that the design influences of Von Braun, Bekker, and Pavlics had already informed a whole generation of spacecraft designers since the 1950s. Given the recollections that San Juan’s daughter has of MSFC, I can easily believe that he did indeed have access to NASA material and personnel while putting together the MOLAB study, including Wernher Von Braun himself.
Given this, we can conclude that San Juan conceptualized a lunar rover along the lines of existing work in the field, but not the rover finally contracted to Boeing and GM/Delco for Apollo 15, 16, and 17. Nikodemski gives us the word on that.
(In some ways, I wish the MOLAB project had pushed through; it looks remarkably ambitious with the equipment proposed by the Hayes study. Note how the scale of their lunar lander is much larger than the Grumman LM, and part of the plan involved a network of LMs forming a decentralized lunar base. I’m sure Von Braun would have approved.)
Next entry, I’ll explore the differences and similarities between San Juan’s proposed rover and the actual Apollo LRV.
Space Get – a small change
The three or four of you who follow Space Get may have noticed a little change in the weblog description: it now just says “Spaceflight video sticky-ball,” omitting mention of “images and other media.” The reason: easy embed fields on YouTube and Google Video.
When I want to post an image (usually NASA public domain photos), the process goes like this: save image locally, upload to Blogger, decide on a size and alignment, tweak Blogger’s auto-generated image tag, give title, publish. When it comes to video, however, it’s a simpler matter involving no file transfer: copy URL to Link field, copy embed code to body, give title, publish. A step or two shorter, no messy save/open dialog boxes, much time saved.
It seems ironic that still images should be harder to post than moving videos, but the YouTube model of offering open embedding really clinches it, making videos much faster to post than photos — and if posting to Space Get weren’t a fast affair it wouldn’t be tenable for me. Plus, I don’t need to worry about storage or bandwidth limits. Perhaps if I could implement an imgred-like solution, or if someone on Flickr had a huge cache of current and historical iconic spaceflight imagery, I might do photos more often, but as it is, Space Get is more about videos now.
Also, video is way more awesome. It’s moving pictures!
(As a concession, I’ve added a feed links box to the Space Get sidebar, grabbing links from my del.icio.us space tag. Those links will often contain imagery.)
