Claire had a birthday around the time of the transit of Venus between us and the sun. I rushed home from work and gathered a bunch of optics and parts. The old Canon FD lenses couldn't be focused quite right. Ditto for the old slide projector lenses. The 12x50 binoculars bungee corded to an old tripod did the trick!
Thanks to the people that threw up a webpage dedicated to viewing the transit. The tips came in handy. Sure, it was a shadow on a projected image but we felt like we had done something wonderful. Claire had been at a K.U. engineering camp earlier in the day and was happy to be doing some practical science.
I am out on travel at the moment. This blog is on scheduled post mode. Please leave a comment if you so choose and I will moderate it when I return. Thanks!
A blog about all kinds of vintage technology from simple mechanisms of the late 1800s through electronics and robotics of the 1980s. Many posts will be typecast and some will be off topic bits from everyday life. The blog will wander and meander with my quasi-evolving and ever changing interests.

Opportunity: Hail the Amazing Rover!
NASA's Opportunity rover is now 8 1/2 years (3043 days) into its 92 day mission and still going strong! It powered up after its fifth Martian winter and is on the move. It is a little pokey given the amount of dust that is collecting on the solar panels. Still, we at the House Full of Nerds are impressed at this engineering accomplishment. This little guy landed on Mars on January 25, 2004.
The twin rover, Spirit, became mired in deep sand and its last communication with Earth was on March 22, 2010. Opportunity is currently alone on the red planet, but will be joined by the next generation in rover technology in August, 2012. Curiosity is a substantial mobile laboratory with a nuclear power source. The landing system is unique and we are hoping for a good start for the mission.

Congratulations to Opportunity and the many builders and mission operators of NASA. The mission is now open ended. We hope Opportunity keeps producing good science for many days to come.

Discovery from late 2011: Gypsum like deposits caused by free water percolating through rock strata. Opportunity and Spirit both observed evidence of past free water on the surface of Mars. |

The Birthday Blog Post From Space
March, 1964 was a good month. But I am perhaps a bit biased. |
For anyone that has been following this blog, it is no secret that I have a serious love of anything related to space exploration. It's my birthday and I am going to totally date myself by posting National Geographic images from the month I was born. I can't think about my birthday without thinking of growing up during the space race.
The excitement of space travel and technology development was the flip side to growing up with the Vietnam War, the Cold War, duck and cover, and its close cousin Mutually Assured Destruction. I grew up in an era where all of this was shiny and new. Everything smelled like the future. Well, except for cars before emission controls.
This has an interesting resemblance to the 1954 kids book version of the the space suit. |
This is something of a hybrid between the Soviet and U.S. approach to landing. Interesting concept, but probably just as well that was all the idea amounted to. |
I am still amazed by rockets. |
Coming home. Really, the whole thing is just amazing. |
As much appeal as I find in human space travel, I am still excited by our collective activities in space exploration. Four years into the Great Recession, it is hard to comprehend the amount of money it would take to lift people and all the stuff they would require to Mars. From my perspective, we need some really good targets before we take the next steps.
We are doing some incredibly good science between our robotic and remote sensing servants. As of March 19, 2012, we have collectively cataloged 762 extrasolar planets including one water world. Just this week, we learned that Mercury is a really strange place. NASA Messenger Findings
Although our family mourned the loss of the Mars rover Spirit, Opportunity is beginning its ninth year of its three month mission. Its much larger cousin, Curiosity, is in route to Mars loaded with a comprehensive laboratory tools. Curiosity won't be dependent on solar power. We'll see what lessons have been learned on reliability in design.
Although the NASA shuttle program is no more, the International Space Station has been continuously inhabited for over 12 years and zips by overhead every 90 minutes or so. The U.S. crew members are licensed amateur radio operators. Beyond having access to high powered transmitters for remote control quadrotors, talking with the ISS crew is the coolest thing I can do with my new FCC Technician license.
Granted, my kids have a space cheerleader at home and friends bound to be future software, computer and robotics engineers. Although human space flight is a big deal for them, they are equally excited about everything else going on in space research. At some point we'll probably try out the crowd sourced SETI Live program. http://www.setilive.org/
For me, space is all about inspiration. I'm thankful for the pioneering work that has gotten us this far. I'm also excited for the future of space exploration. When we decide to go, it will no doubt be to someplace incredibly interesting. Maybe one of our emissaries will get to say hi to Spirit in person.

Dear Mr. Glenn,
Thanks for your role in the beginning of America's race for the Moon.
