Video of ArduSat NASDAQ Interview

NanoSatisfi founder Peter Platzer appeared on the Japanese NASDAQ TV feed to talk about the ArduSat satellite.

ArduSat is an open-source arduino-based nanosatellite. It will have an extensive sensor-suite onboard and will allow users to upload their own code and run their own experiments.

ArduSat will use a GomSpace NanoCom U482C which is a half-duplex UHF transceiver, capable of up to 3W, operating in the 435-438 MHz amateur radio satellite band. It implements Forward Error Correction (FEC) and Viterbi coding based on the CCSDS standards in order to improve reliability and throughput of the space link.

The project is raising donations through the Kickstarter site at http://nanosatisfi.com/ In just over a week they raised more than $43,000 in pledges from almost 300 donors.

STS-56 was a Space Shuttle Discovery mission to perform special experiments. The mission launched from Kennedy Space Center, Florida, on April 8, 1993.

There were four radio hams on STS-56, Kenneth D. Cameron KB5AWP, Mike Foale KB5UAC, Ellen Ochoa KB5TZZ, Kenneth Cockrell KB5UAH.

Ellen Ochoa KB5TZZ was the first Hispanic woman to go into space. She went on to complete four space shuttle flights and become Deputy Director of the Johnson Space Center.

The primary payload of the flight was the Atmospheric Laboratory for Applications and Science-2 (ATLAS-2), designed to collect data on the relationship between the sun’s energy output and Earth’s middle atmosphere and how these factors affect the ozone layer. It included six instruments mounted on a Spacelab pallet in the cargo bay, with the seventh mounted on the wall of the bay in two Get Away Special canisters.

Narrated by the Commander and crew, this video contains footage selected by the astronauts, as well as their comments on the mission. Footage includes launch, onboard crew activities, and landing.

The amateur radio aspect of the mission features at 09:58 into the video.

Students Build Supercapacitor Battery for next ARISSat

On Feb. 3, 2006, astronauts tossed an old spacesuit off the International Space Station. Inside was an amateur radio transmitter, a temperature sensor and some batteries.

The suit was a DIY satellite. It circled the Earth twice, repeating a greeting recorded in multiple languages; ham radio operators listened in as it passed overhead.

Then the batteries died.

The Radio Amateur Satellite Corporation, or AMSAT, tried again in 2011. The battery in that satellite, a more traditional box design, also failed.

For the next model, AMSAT, a volunteer group, turned to the School of Engineering at Penn State Erie, The Behrend College. Three students designed a brand-new battery: a 1.8 kg cube powered by 15 supercapacitors, each roughly the size of a film canister.

The battery was built to handle 16 charge cycles in a 24-hour period. That will power the satellite in dark orbits, when the solar panels are not facing the sun.

To activate the battery before those solar panels charge, the students – David Jesberger, of St. Marys; Kathleen Nicholas, of Pittsburgh; and Jacob Sherk, of Elizabethtown – added four 9-volt Duracells.

AMSAT hopes to fit the satellite into a rocket payload and onto the International Space Station sometime in 2013. The astronauts won’t have to do much with it.

“It’s simple by design. They flip a switch, and they throw it out,” said Dakshina Murthy Bellur, an assistant professor of electrical and computer engineering at Penn State Behrend. He supervised the battery work, which counted as the students’ senior capstone project.

All three students have since graduated. All three have jobs: Nicholas and Jesberger signed on with defense contractors, and Sherk works at the Three Mile Island nuclear power plant.

They continue to track the AMSAT project. They want to know when their battery, upon which they laser-etched with their names and a Nittany Lion paw print, gets a launch date.

“That’s going to be cool,” Jesberger said. “We’ll have our signatures in space.”

10th Anniversary of OSCAR 7’s Return To Life

Artists impression of OSCAR 7 in Space

The amateur radio satellite AMSAT-OSCAR 7 was launched by a Delta rocket from Vandenberg Air Force Base on November 15, 1974 and provided many years of service until it went silent from battery failure in mid 1981.

For 21 years nothing more was heard until June 21, 2002 when Pat Gowen G3IOR came across a beacon sending slow 8 -10 wpm CW on 145.973.8 MHz. It sounded like old OSCAR satellite telemetry, it had the familiar HI HI followed by a string of numbers in groups of three. After monitoring by many radio amateurs it turned out to be OSCAR-7, and it seemed to have come back from the dead.

Pat’s email to the AMSAT Bulletin Board announcing his discovery can be seen at
https://web.archive.org/web/20180517020245/https://www.amsat.org/amsat/archive/amsat-bb/200206/msg00525.html

It is believed that in 1981 the batteries failed short-circuit, however, in 2002 they became open-circuit enabling the satellite to run again from the solar panels. Since that day OSCAR 7 has been operational when in sunlight and provided radio amateurs with many long distance (DX) SSB/CW contacts.

Remember when working OSCAR 7 use the least uplink power possible to minimize your downlink power usage, and maximize the number of simultaneous contacts supported in the passband.

A BBC News report Radio ham finds lost satellite about the reception of OSCAR 7 by Dave Rowan G4CUO can be seen at http://news.bbc.co.uk/1/hi/england/2149381.stm

A collection of photos by Dick Daniels W4PUJ taken during the construction, test and launch of the AMSAT-OSCAR 7 spacecraft in 1973 and 1974 can be viewed at http://n4hy.smugmug.com/AMSAT/AMSAT-Oscar-7

Details of the June 1981 battery failure and a list of AO-7’s achievements can be found on pages 37-40 of the 1981 AMSAT Satellite Report Archive at http://www.ka9q.net/asr-1981.pdf

Later pages of the 1981 ASR archive note that amateurs continued listening to the AO-7 frequencies in the hope it would return. They were reports of a weak beacon carrier in July and August 1981 but although amateurs continued listening nothing was heard in the months after that.

The Women in STEM High School Aerospace Scholars  (WISH) project is sponsoring two six-day summer camps for rising high school seniors that should feature a presentation by astronaut Shannon Walker KD5DXB and an Amateur Radio contact with the International Space Station (ISS).

Eighty-four female high school students from 29 states will plan a simulated mission to Mars and experience life as an engineer or scientist when NASA’s Johnson Space Center in Houston hosts two events focused on science, technology, engineering and mathematics (STEM) in June and July.

The young women will work in teams with female NASA mentors to develop mission plans for launching to Mars, living and working there, and integrating the many components necessary for a successful planetary mission. They will work within the confines of a fictitious budget and build several small mockups of vehicles to demonstrate a successful launch and landing of the Mars spacecraft.

“WISH gives some of our brightest future innovators a chance to experience some of the exciting challenges that NASA engineers and scientists face on a daily basis,” said Johnson Deputy Director and four-time space shuttle astronaut Ellen Ochoa KB5TZZ. “It shows the young women that there are a variety of opportunities for them in technical fields.”

Young women participating June 24-29 will hear a first-hand account of life in space from NASA astronaut and radio amateur Shannon Walker KD5DXB. Participants July 8-13 will have a chance to speak with a current space station astronaut via ham radio as part of the Amateur Radio on the International Space Station program, a NASA educational initiative that facilitates direct links between students and astronauts.

The young women were selected based on completion of interactive, online lessons focused on space exploration and mapped to national education standards, academic merits and geographic diversity. The WISH program encourages young women to pursue science, technology, engineering and mathematics degrees and exposes them to the real-world applications of STEM careers at NASA. This program is in its second year. It began as a NASA accompaniment to the White House Council on Women and Girls.
