Fox-1 Project Educational Goals Align With NASA ELaNa Requirements
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. AMSAT will work with NASA 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.
In an article published in the AMSAT Journal, AMSAT Vice-President of Engineering, Tony Monteiro, AA2TX noted that meeting NASA's educational goals for Science, Technology, Engineering, and Math (STEM) was the cornerstone in the successful acceptance of Fox-1 into the ELaNa project.
Fox-1 continues AMSAT's long record of success as an all-volunteer organization providing access to space communications for students in a curriculum setting as well the private citizen.
The Fox-1 communication package provides a learning and technological stepping-stone using commonly available amateur radio equipment. Students gain first-hand experience in setting up and operating equipment, orbital prediction, communication to distant places, and growth in overall space literacy. In the classroom, Fox-1 will allow schools, teachers, and students to actively participate in space technology with a unique experimental hands-on learning approach that includes communicating through a satellite in orbit.
All of the Fox-1 experiment and telemetry data will be collected and stored on our internet server and made publicly available for use in the classroom and shared with the CubeSat community.
In addition to mentoring university student cubesat mission teams, AMSAT satellites have also hosted university experiments aboard our spacecraft. In addition to the communications package, Fox-1 will host an experimental payload developed as a capstone project at Penn State University. The Penn State project will have impact on future CubeSat systems as the students design, construct, and orbit an attitude experiment based on a 3-axis micro-electro-mechanical gyroscope.
Fox-1 Project Reviews
The Fox-1 Team participated in a Merit Review and Feasibility Review with a panel including education and industry experts at the Doctorate level, a developer of 29 satellites, and directors of research.
The results of the Fox-1 Merit Review found:
- AMSAT "nailed" the NASA education requirements of the NASA Education Strategic Coordination Framework and the NASA Education Implementation Framework. In fact, AMSAT has a history of space education that pre-dates most university programs.
- The Fox-1 program will be accessible to an entire classroom or school with only the teacher or outside volunteer requiring an amateur radio license.
- The archive of telemetry data collected during actual space flight will prove valuable in future educational projects that have yet to be imagined.
The results of the Fox-1 Feasibility Review found:
- While AMSAT relies on an all-volunteer development team the tremendous depth and experience of the Fox-1 team far exceeds the capability of a typical CubeSat team. AMSAT has developed its satellites this way for 40 years and has never missed a launch.
- AMSAT does not rely on critical technology for flight and leverages our experience from prior successful missions:
- 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.
AMSAT's Fox-1 project timeline is based on targeting a launch in the second half of 2013. NASA will determine on which flight each of the Project ELaNa CubeSats fly. Read NASA's CubeSat Launch Initiative web page including AMSAT's participation here.

EPFL Announces Nanosat Ion Drive - To The Moon on 100 mL of Fuel
An article posted on space-travel.com reported the EPFL University in Switzerland announced the first prototype of a new, ultra-compact motor that will allow small satellites to journey beyond Earth's orbit.
EPFL said the MicroThrust ion motor will be capable of reaching the Moon using just a tenth of a liter of fuel. The complete thruster weighs just a few hundred grams and is specifically designed to propel small (1-100 kg) satellites, which it enables to change orbit around the Earth and even voyage to more distant destinations - functions typically possible only for large, expensive spacecraft.
Instead of a combustible fuel, the new mini motor runs on an "ionic" liquid, in this case the chemical compound EMI-BF4, which is used as a solvent and an electrolyte. It is composed of electrically charged molecules (like ordinary table salt) called ions, except that this compound is liquid at room temperature. The ions are extracted from the liquid and then ejected by means of an electric field to generate thrust. This is the principle behind the ionic motor: fuel is not burned, it is expelled.
After six months of acceleration, the microsatellite's speed increases from 24,000 km/h, its launch speed, to 42,000 km/h. The acceleration is only about a tenth of a millimeter per square second, which translates into 0-100 km/h in 77 hours. But in space, where there is no friction to impede motion, gentle but steady acceleration is the way to go.
"We calculated that in order to reach lunar orbit, a 1-kg nanosatellite with our motor would travel for about six months and consume 100 milliliters of fuel," explains Muriel Richard, a scientist in EPFL's Swiss Space Center.

European ATV-3 Edoardo Amaldi Arrives at ISS & Performs Reboost
After a successful launch on March 23, the heaviest cargo ship ever has arrived and docked to the International Space Station. The 20-ton European ATV-3 cargo ship, named "Edoardo Amaldi" after the Italian physicist and spaceflight pioneer, made a "smooth and gentle" docking on March 28. It delivered 7 tons of food, drinking water, clothing, oxygen, spare parts and fuel for the 6-member ISS crew.
A video of the docking with ISS can be viewed at:
On Saturday, March 31 the ATV reboosted the space station's orbit to 389.8 km. The ATV's thrusters ran for 351 seconds, increasing ISS velocity by 1.0 m/s and boosting average altitude by 1.73 km. This is a standard test performed as soon as possible after docking.
The successful test burn means that ATV is ready for a series of larger planned reboosts (the first expected on 5 April) and to conduct debris avoidance manoeuvres when necessary.

An article posted on spaceflightnow.com on April 2 reports that the huge cargo freighters, weighing more than 20 tons fully loaded, will stop flying in 2014 when the fifth resupply craft delivers equipment to the International Space Station. ESA member states decided to discontinue the program after briefly considering redesigning the throwaway cargo craft to return hardware in a hardened re-entry capsule.
The ESA published a new video on their youtube channel showing ESA astronaut André Kuipers and cosmonaut Oleg Kononenko opening the hatch to the ATV and begin unloading the cargo.
