AMSAT Fox-1 Cubesat Selected for NASA ELaNa Launch Collaboration
Project ELaNa, NASA's "Educational Launch of NanoSat" managed by the Launch Services Program at the Kennedy Space Center, announced on February 10 that the AMSAT Fox-1 cubesat has been selected to join the program.
NASA will work with AMSAT in a collaborative agreement where NASA will cover the integration and launch costs of satellites deemed to have merit in support of their strategic and educational goals.
AMSAT teamed with the ARRL to write and deliver the 159 page educa- tional proposal to NASA. Letters documenting the importance of AMSAT's satellites in the education programs at the ARRL and also at the Clay Center for Science and Technology at the Dexter and Southfield schools in Brookline, MA, were important parts of our proposal.
AMSAT President Barry Baines, WD4ASW said, "The ELaNA Launch opportunity marks AMSAT's return to space after the conclusion of the successful ARISSat-1/KEDR flight. We need to get the flight Fox-1, along with an operational flight backup satellite, built, integrat- ed, tested, and delivered. Our ability to provide a spacecraft and get it launched is dependent upon the active support of our donors who wish to see Fox-1 fly."
AMSAT Vice-President of Engineering, Tony Monteiro, AA2TX noted this will provide a launch opportunity for AMSAT's next generation of FM repeater satellites with features and operation beyond the experience of AO-51. AMSAT's Fox-1 Engineering Team is making progress developing the advanced satellite that will provide these features:
+ Fox-1 is designed to operate in sunlight without batteries once the battery system fails. This applies lessons learned from AO-51 and ARISSat-1 operations.
+ In case of IHU failure Fox-1 will continue to operate its FM repeater in a basic, 'zombie sat' mode, so that the repeater remains on-the-air.
+ Fox-1 is designed as the immediate replacement for AO-51. Its U/V (Mode B) transponder will make it even easier to work with modest equipment.
+ From the ground user's perspective, the same FM amateur radio equipment used for AO-51 may be used for Fox-1.
+ Extending the design, Fox-2 will benefit from the development work of Fox-1 by adding more sophisticated power management and Software Defined Transponder (SDX) communications systems.
The Fox-1 Project presents an opportunity to literally put your call- sign on the Fox hardware. AMSAT is looking for major donations to help underwrite the cost of solar cells/panels, one of the more significant expenses of the project.
These solar cells are needed for the flight unit as well as for the a flight spare. As Fox-1 will have solar cells on all six sides of the spacecraft and given the relatively small surface area available on each side (at most 4" by 4" per side), AMSAT needs to invest in high efficiency solar cells to gain as much power as possible to operate the spacecraft.
Several opportunities to make your donation to keep amateur radio in space include:
+ Return the form sent with the letter to reply with your donation for the Fox-1 Project. - All donations over $40 will receive a Fox pin. - Donations of $120 or more qualify you for AMSAT President's Club
+ Call Martha at the AMSAT Office +1-888-FB AMSAT (1-888-322-6728) + Paypal donation widget on the main page at: http://www.amsat.org + Paypal donation widget for Project Fox at: http://www.amsat.org/amsat-new/fox/ + You can also go to the Paypal site and send your donation to [email protected]. + The AMSAT Store: http://www.amsat-na.com/store/categories.php

ARISS Contact to Celebrate 50th Anniversary John Glenn Over Perth
On the 20th of February 1962 a Mercury-Atlas 6 spacecraft called "Friendship 7" was launched. In the hot-seat was Astronaut, John Glenn. The objective was to place a man into earth orbit, observe his reactions to the space environment and safely return him to earth to a point where he could be readily found.
During the first orbit of three, the spacecraft came into radio range of the Muchea Tracking Station where the first Australian space radio contact was made by Gerry O'Connor who spoke with John Glenn as he passed overhead.
One of the questions that was posed for this flight was "Can you see the cities of Earth from space?" To help answer that question, the people of the City of Perth all turned their lights on as John Glenn flew over. The answer to the question was a resounding "YES!", and Perth was nicknamed "The City of Light".
Fifty years later on February 20, 2012 young people from Western Australia will have the chance to ask a question of an astronaut or cosmonaut currently residing on the International Space Station. There will be a live radio and video connection to the space station at the Northbridge Piazza in Perth, Western Australia. Ten lucky winners of the student competition, selected from primary and secon- dary schools, will get to ask questions, and receive their answers in real time as the space station flies overhead.
From a technical perspective, ARISS will configure a direct amateur
radio link between the ISS and ham operator, Dick Flagg, AH6NM, in Honolulu. In Perth, members of the Hills Amateur Radio Group will provide a phone link between AH6NM and Northbridge Piazza so the stu- dents can converse with the astronaut. Tony Hutchison, VK5ZAI, ARISS Mentor for Australia is conducting the behind the scenes preparation.
The event begins at 17:00PM Perth time (0900 UTC) on February 20. The currently scheduled contact time is approximately at 10:22 UTC, sub- ject to last minute change depending upon events aboard the ISS or orbit changes.
In addition to the ARISS contact, web-streaming and other space act- ivities such as a radio telescope, optical telescopes, museum exhibi- tions, an address by the Lord Mayor of Perth, a video message from John Glenn and a presentation by the Western Australia Chief Scientist are planned.

Open Mission Control Software for CubeSat Project Teams
CubeSat developers may be interested in learning more about the Open Mission Control software, an open source, open access software for monitoring and controlling small spacecraft. The software is designed to provide an application and framework that can be adapted quickly and easily to support a variety of spacecraft including CubeSats, myPocketQubs and NanoLab experiments, and sounding rocket and high altitude balloon experiments. The team include students, space pro- fessionals, educators and enthusiasts from around the world, all working together to build a great mission control application for small spacecraft projects.
The Open Mission Control framework consists of the application and graphical user interface which contain the basic structure of the program, and the Open Mission Control toolbox, which provides a number of ready to use functions typically required for mission control applicationa.
The Open Mission Control application and graphical user interface can be adapted to a project quickly and easily, by populating them with elements from the Open Mission Control toolbox and other stan- dard library elements. This approach allows also users with limited programming experience to create sophisticated mission control soft- ware by building on a solid basic implementation. Use and verification.
Designed to work with any spacecraft project, the first flight mis- sion that is expected to use Open Mission Control is myPocketQub 442. myPocketQub 442 was selected to fly as a pocket spacecraft attached to UKube-1, the first United Kingdom Space Agency CubeSat. It is expected to be the first mission controlled by Open Mission Control and to demonstrate and verify various use cases:
+ The first use case is for professional monitoring, command and control of a real spacecraft.
+ The second use case involves schools and universities using Open Mission Control to upload their virtual payloads for their Open- Space365 projects, monitor their experiments as they run and down- load the data for analysis.
+ The third use case involves the use of Open Mission Control as monitoring software for the various scientific and engineering sub-payloads that will fly on myPocketQub 442. The students con- ducting these experiments will use Open Mission Control to access and store the data from these payload experiments for analysis and research.
+ The fourth use case is communication with engineering models of the real spacecraft which will be made available on the Internet. These engineering models are duplicates of the flight hardware and allow Open Mission Control to command and monitor them and their sub-payloads in real time and to simulate different critical mis- sion phases under real conditions.

NASA astronaut Janice Voss, KC5BTK Passes
NASA astronaut Janice Voss passed away from cancer overnight. One of only six women who have flown in space five times, Voss' career was highlighted by her work and dedication to scientific payloads and exploration. Janice supported SAREX during her flights on the Space Shuttle. She was a phone-in speaker during one of AMSAT's multi-media Dayton Forum presentations with Roy Neal as MC. Janice held the callsign KC5BTK.
Voss began her career with NASA in 1973 while a student at Purdue University. She returned to NASA in 1977 to work as an instructor, teaching entry guidance and navigation to space shuttle crews. After completing her doctorate in 1987, she worked within the aerospace industry until she was selected as an astronaut in 1990.
Voss' first spaceflight mission was STS-57 in 1993, the first flight of the Spacehab module. She next flew on STS-63 in 1995, a mission to the Mir space station, and third flight of Spacehab. She also flew as a payload commander on STS-83 in 1997 with the Microgravity Science Laboratory, but the mission was cut short due to problems with one of the orbiter's three fuel power generation units. Voss, the crew and MSL flew again as the STS-94 MSL-1 Spacelab mission, focused on materials and combustion science research in microgravity.
Her last mission was STS-99 in 2000, a flight to the International Space Station as part of the Shuttle Radar Topography Mission which mapped more than 47 million square miles of the Earth's land surface. In total, Voss spent more than 49 days in space.
Peggy Whitson, chief of the Astronaut Office said, "By improving the way scientists are able to analyze their data, and establishing the experimental methods and hardware necessary to perform these unique experiments, Janice and her crew ensured that our space station would be the site of discoveries that we haven't even imagined."

SumbandilaSat SO-67 Amateur Transponder Recovery Work in Progress
It would appear that prior reports on the demise of South Africa's SumbandilaSat were 'greatly exagerated' (with apologies to author Mark Twain).
A report on the Southern African AMSAT website says partial recov- ery is possible for Amateur Radio Operation to possibly resume in March 2012.
"We have not given up on our efforts to get SumbandilaSat working again even if it is only partially", said Johan Lochner ZR1CBC who is spending much time on the recovery process and many nights burn- ing the midnight oil working on new and more intelligent algorithms. He and his colleagues are making every effort to get the satellite working again.
SumbandilaSat experienced a corruption in the programme memory of one of the power switches. This is the interface unit which con- trols a robust orientation control implementation system which is using output from the magnetic sensors to point the solar panels to- wards the sun in a safe mode scenario when for example communica- tions with the ground segment was not possible for a few days.
The corruption of the program memory prevented the magnetic inter- face unit from automatically switching on after power-up and thus preventing access to measurements taken by the magnetometer.
Johann said, "As a result of the malfunction of the magnetic control unit the satellite started to slowly point away from the sun with intermittent sun eclipses. When there was no power flowing from the solar cells the batteries drained and we could not in a safe way communicate with the satellite, so we backed off. Once we determined this pattern we stopped communicating with the satellite when we did not see sufficient charge on the batteries. At other times we had good communication when could diagnose what was going on. Dur- ing good communication windows that could last 2 or 3 days we tried to diagnose the exact nature of the problem in the same way as we had done before and we started to implement a fix. The particular power switch that failed was already the redundant one so we were in a worse state than before."
SumbandilaSat controllers implemented automated ground segment soft- ware to make contact with the satellite from both SANSA Space Opera- tions and the Electronic Systems labs at SU. The objective was to contact the satellite automatically and to try to implement the recovery procedure and also notify the team if any contact was made.
Johann continued, "By mid-November 2011 we again made contact with SumbandilaSat and set in place a planned recovery procedure. Within 3-4 days we came to the conclusion that the main battery had failed. Earlier the intermittent contact was because the battery could not be fully charged and that satellite power bus was too low for the processors and transmitter to function. We surmised that during the month that we had no contact that the battery must have gone open circuit. With the battery no longer on the power bus, the voltage on the bus would rise to 28.5 volts and supply enough current to support operations when SumbandilaSat was in full sunlight."
The SumbandilaSat concludes, "We are determined to get this working and to maintain the scientific value of the satellite as much as possible. Johann's focus is now on getting the amateur radio trans- ponder working, which with the loss of AO-51 will be a great asset to amateur radio satellite activity. By the end of February we hope to achieve this!"
