Ames Amateur Radio Club Demonstrates at Yuris Night: April 12, 2008
The NASA Ames Amateur Radio Club (AARC), along with help from some other amateur radio groups, demonstrated exciting wireless communications capabilities during Yuris Night. One of the activities showed how signals could be sent from earth to the moon, and back to the earth, using surface of the moon as a reflector (earth-moon-earth or EME) for moonbounce communications. The other activity, Amateur Television (ATV), demonstrated how live video feeds could be sent between locations at Yuris Night, and also transmitted via a repeater to anyone in the south bay area, using a regular TV to tune into the over-the-air signal.
The EME effort was significantly assisted by folks from the 50 MHz-and-up club, as well as folks associated with the Jamesburg dish (http://www.jamesburgdish.org), in Cachagua Valley, near Salinas. Also participating in this EME activity were several students from the San Jose State University amateur radio club. Led by Jim Moss, the participants were able to successfully communicate with folks in Texas and Europe using a dish antenna, and able to hear stations using a yagi beam antenna. We also had a yagi array lent from M2 Antenna Systems Inc.
Amateur television (ATV) effort demonstrated how anyone with a ham radio license can transmit TV using same techniques just like professional broadcasters. Assisted by members of the K6BEN-ATV group, activities were continuously shown on amateur television throughout the south bay area. Anyone using a TV with an aerial antenna, and tuned to cable channel 57 would have been able to see and hear these transmissions. Using conventional equipment, a rover with video camera (similar to what a news broadcaster might use) and a portable lowpower TV transmitter to send video and audio live throughout the event area. Anyone using a TV with an aerial antenna, and tuned to cable channel 58 would have been able to see and hear the roving transmissions.
Yuris Night Bay Area was a huge public relations bonanza for NASA, particularly with a large number of 20-somethings attending (average age of NASA people is 50). This illustrates many paid $40-50, arrived on their own time, not affiliated with the government or the aerospace industry, and never seen or heard the kinds of stuff NASA does. They may have come for the shows and music but they saw and interacted with those who are excited about exploration and technology. Event is the world space party commemorating the first human space flight by Yuri Gagarin (April 12, 1961).
Center director Pete Worden stated, We clearly communicated the value of spaceflight to this generation and future generations, and you could see that many of our passengers enjoyed learning what NASA and Ames are all about in addition to enjoying the music, dance and art that made the day so colorful.

Yuris Night a Success!
April 13, 2007 at NASA Ames Hangar 211 (Moffett Field)
from David Hartzell
Thanks to all for participating in the AARC exhibit at Yuris Night.
Turnout was great, despite the performance of the satellite demos. But we heard a few sats and made some contacts. I have also received several emails from our exhibit visitors. I think we may have really wowd the public.
Here are a few ideas/lessons learned for the next time:
Yuris Night at NASA Ames Research Center:
This unprecedented event brought together thousands of people from the science, technology, music, art and dance communities in celebration of humanitys accomplishments in space.
Featuring a keynote talk by Anousheh Ansari, local and international music acts including Plaid, Telefon Tel Aviv and Bluetech will be woven through a schedule chok full of live demonstrations from astronomy, robotics, physics, engineering, and technology late into the night.
Celestial light performances and unique acrobatics will dazzle and entertain. Large scale sculpture, interactive multimedia installations, and awe-inspiring NASA footage and documentaries will be displayed both in the hangar and outside on the adjoining tarmac.
