Amateur Radio on the International Space Station

Amateur-satellite service Amateur Radio on the International Space Station (ARISS) - operating in the Amateur-satellite service - is a project sponsored by various entities and carried out by astronauts and cosmonauts on the International Space Station who also have an amateur radio license. The program was previously called SAREX, the Space Amateur Radio Experiment, and before that the Shuttle Amateur Radio Experiment. In 2011, Kenwood Electronics launched an advertising campaign capitalizing on the fact that their TM-D700A transceiver is currently in use on the ISS.[1]

Amateur radio operators all over the world are able to speak directly to astronauts/cosmonauts via their handheld, mobile, or home radio stations. Low power radios and small antennas can be used to establish communications. It is also possible to send digital data to the space station via laptop computers hooked up to the same radio and antenna, similar to an email communication, except that it uses radio frequencies instead of telephone or cable connections.

The space station occupants work a standard work day and have breaks in the evening and during meals. While on break, some of them will spend some time communicating with "earthlings" via amateur radio.

Alexander Gerst

Alexander Gerst (born 3 May 1976 in Künzelsau, Baden-Württemberg) is a German European Space Agency astronaut and geophysicist, who was selected in 2009 to take part in space training. He was part of the International Space Station Expedition 40 and 41 from May to November 2014. Gerst returned to space on June 6, 2018, as part of Expedition 56/57. He was the Commander of the International Space Station. Alexander returned to Earth on December 20, 2018. Upon the end of his second mission, he holds the most time in space than any active ESA astronaut (362 days), succeeding Italian astronaut Paolo Nespoli, and German ESA astronaut Thomas Reiter, who formally held the record for the longest time in space for any active or retired ESA astronaut.

Amateur radio

Amateur radio, also known as ham radio, describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government's radio regulations.

Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum. This enables communication across a city, region, country, continent, the world, or even into space. In many countries, amateur radio operators may also send, receive, or relay radio communications between computers or transceivers connected to secure virtual private networks on the Internet.

Amateur radio is officially represented and coordinated by the International Amateur Radio Union (IARU), which is organized in three regions and has as its members the national amateur radio societies which exist in most countries.

According to an estimate made in 2011 by the American Radio Relay League, two million people throughout the world are regularly involved with amateur radio. About 830,000 amateur radio stations are located in IARU Region 2 (the Americas) followed by IARU Region 3 (South and East Asia and the Pacific Ocean) with about 750,000 stations. A significantly smaller number, about 400,000, are located in IARU Region 1 (Europe, Middle East, CIS, Africa).

Automatic Packet Reporting System

Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data.

APRS data are typically transmitted on a single shared frequency (depending on country) to be repeated locally by area relay stations (digipeaters) for widespread local consumption. In addition, all such data are typically ingested into the APRS Internet System (APRS-IS) via an Internet-connected receiver (IGate) and distributed globally for ubiquitous and immediate access. Data shared via radio or Internet are collected by all users and can be combined with external map data to build a shared live view.

APRS has been developed since the late 1980s by Bob Bruninga, call sign WB4APR, currently a senior research engineer at the United States Naval Academy. He still maintains the main APRS Web site. The initialism "APRS" was derived from his call sign.

ESA Scientific Research on the International Space Station

The following page is a list of scientific research that is currently underway or has been previously studied on the International Space Station by the European Space Agency.

Expedition 1

Expedition 1 was the first long-duration stay on the International Space Station (ISS). The three-person crew stayed aboard the station for 136 days, from November 2000 to March 2001. It was the beginning of an uninterrupted human presence on the station which continues as of March 2019. Expedition 2, which also had three crew members, immediately followed Expedition 1.

The official start of the expedition occurred when the crew docked to the station on 2 November 2000, aboard the Russian spacecraft Soyuz TM-31, which had launched two days earlier. During their mission, the Expedition 1 crew activated various systems on board the station, unpacked equipment that had been delivered, and hosted three visiting Space Shuttle crews and two unmanned Russian Progress resupply vehicles. The crew was very busy throughout the mission, which was declared a success.

The three visiting Space Shuttles brought equipment, supplies, and key components of the space station. The first of these, STS-97, docked in early December 2000, and brought the first pair of large U.S. photovoltaic arrays, which increased the station's power capabilities fivefold. The second visiting shuttle mission was STS-98, which was docked in mid-February 2001 and delivered the US$1.4 billion research module Destiny, which increased the mass of the station beyond that of Mir for the first time. Mid-March 2001 saw the final shuttle visit of the expedition, STS-102, whose main purpose was to exchange the Expedition 1 crew with the next three-person long-duration crew, Expedition 2. The expedition ended when Discovery undocked from the station on 18 March 2001.

The Expedition 1 crew consisted of an American commander and two Russians. The commander, Bill Shepherd, had been in space three times before, all on shuttle missions which lasted at most a week. The Russians, Yuri Gidzenko and Sergei K. Krikalev, both had previous long-duration spaceflights on Mir, with Krikalev having spent over a full year in space.

International Space Station

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000. It has been inhabited continuously since that date. The last pressurised module was fitted in 2011, and an experimental inflatable space habitat was added in 2016. The station is expected to operate until 2030. Development and assembly of the station continues, with several new elements scheduled for launch in 2019. The ISS is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised habitation modules, structural trusses, solar arrays, radiators, docking ports, experiment bays and robotic arms. ISS components have been launched by Russian Proton and Soyuz rockets and American Space Shuttles.The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It circles the Earth in roughly 92 minutes and completes 15.5 orbits per day.The ISS programme is a joint project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station is divided into two sections, the Russian Orbital Segment (ROS) and the United States Orbital Segment (USOS), which is shared by many nations. As of January 2018, operations of the American segment were funded until 2025. Roscosmos has endorsed the continued operation of ISS through 2024, but has proposed using elements of the Russian segment to construct a new Russian space station called OPSEK. In December 2018, the U.S. Senate extended ISS funding until 2030.The ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations as well as Skylab from the US. The station has been continuously occupied for 18 years and 141 days since the arrival of Expedition 1 on 2 November 2000. This is the longest continuous human presence in low Earth orbit, having surpassed the previous record of 9 years and 357 days held by Mir. It has been visited by astronauts, cosmonauts and space tourists from 18 different nations. After the American Space Shuttle programme ended in 2011, Soyuz rockets became the only provider of transport for astronauts at the ISS.

The station is serviced by a variety of visiting spacecraft: the Russian Soyuz and Progress, the American Dragon and Cygnus, the Japanese H-II Transfer Vehicle, and formerly the American Space Shuttle and the European Automated Transfer Vehicle. The Dragon spacecraft allows the return of pressurised cargo to Earth (downmass), which is used for example to repatriate scientific experiments for further analysis. The Soyuz return capsule has minimal downmass capability next to the astronauts.

As of 14 March 2019, 236 people from 18 countries had visited the space station, many of them multiple times. The United States sent 149 people, Russia sent 47, nine were Japanese, eight were Canadian, five were Italian, four were French, three were German, and there were one each from Belgium, Brazil, Denmark, Kazakhstan, Malaysia, the Netherlands, South Africa, South Korea, Spain, Sweden, and the United Kingdom.


Kedr (Russian: кедр meaning Siberian pine; Yuri Gagarin's callsign during the Vostok 1 mission) also known as ARISSat 1 and RadioSkaf-2, was an amateur radio minisatellite operated by RKK Energia as part of the Amateur Radio on the International Space Station and RadioSkaf programmes. A follow-up to the SuitSat spacecraft, Kedr was launched to commemorate the fiftieth anniversary of the Vostok 1 mission.

Kedr transmitted 25 greetings in 15 different languages. It also transmitted photos of the Earth, telemetry and scientific data., voice, telemetry and slow-scan television data on a frequency of 145.950 MHz. The satellite was also intended for use in educational programmes. Kedr was a 30-kilogram (66 lb) satellite measuring 55 centimetres (22 in) by 55 centimetres (22 in) by 40 centimetres (16 in). It carried solar cells to generate power, and was expected to operate for six months.For launch, Kedr was stored aboard the Progress M-09M spacecraft, which was launched to resupply the International Space Station. Progress M-09M was launched atop a Soyuz-U carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome at 01:31:39 UTC on 28 January 2011. It docked with the International Space Station at 02:39 UTC on 30 January.Kedr was deployed from the ISS by Sergey Volkov during an extra-vehicular activity on 3 August 2011 and re-entered Earth's atmosphere on 4 January 2012, having spent 154 days in orbit.

"KEDR" was also used as the suffix for several Russian amateur radio Call signs (for example, RS0KEDR) that were active in 2014 around the 80th anniversary of Gagarin's birth.

Naoto Satō

Naoto Satō (佐藤 直人, Satō Naoto, born 1953) is a Japanese amateur astronomer, discoverer of minor planets, and, by profession, a junior high school science teacher. As a planetarian, a member of the professional staff of a planetarium, he has done much for the spread of astronomy in Japan through speaking on planetaria and the results of astronomical observation.In 2001, while working as support staff at JK1ZAM, the club station of Iruma Children’s Center (an educational institution for children in Iruma City), he helped achieve the first ARISS school contact in Japan. Also, in 2003, as a coordinating teacher, he helped accomplish the first solo contact between a junior high school in Japan and the ISS, with the support of JK1ZAM. He regularly spoke on the astronomical talk program Sunset Café at the local radio station "FM CHAPPY 77.7" from December 2006 to November 2008. He held the position of vice-director on the board of the Saitama Planetarium Liaison Council (2007–2008). He supports ARISS (Amateur Radio on the International Space Station), which is a program that offers students an opportunity to experience the excitement of amateur radio by talking directly with crew members of the ISS (International Space Station).The Eos main-belt asteroid 6025 Naotosato, which Takeshi Urata discovered in 1992, was named after him.

Scientific research on the International Space Station

Scientific research on the International Space Station is a collection of experiments that require one or more of the unusual conditions present in low Earth orbit. The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector.Research on the ISS improves knowledge about the effects of long-term space exposure on the human body. Subjects currently under study include muscle atrophy, bone loss, and fluid shift. The data will be used to determine whether space colonisation and lengthy human spaceflight are feasible. As of 2006, data on bone loss and muscular atrophy suggest that there would be a significant risk of fractures and movement problems if astronauts landed on a planet after a lengthy interplanetary cruise (such as the six-month journey time required to fly to Mars).

Large scale medical studies are conducted aboard the ISS via the National Space Biomedical Research Institute (NSBRI). Prominent among these is the Advanced Diagnostic Ultrasound in Microgravity study in which astronauts (including former ISS Commanders Leroy Chiao and Gennady Padalka) perform ultrasound scans under the guidance of remote experts. The study considers the diagnosis and treatment of medical conditions in space. Usually, there is no physician on board the ISS, and diagnosis of medical conditions is a challenge. It is anticipated that remotely guided ultrasound scans will have application on Earth in emergency and rural care situations where access to a trained physician is difficult.Researchers are investigating the effect of the station's near-weightless environment on the evolution, development, growth and internal processes of plants and animals. In response to some of this data, NASA wants to investigate microgravity's effects on the growth of three-dimensional, human-like tissues, and the unusual protein crystals that can be formed in space.The investigation of the physics of fluids in microgravity will allow researchers to model the behaviour of fluids better. Because fluids can be almost completely combined in microgravity, physicists investigate fluids that do not mix well on Earth. In addition, an examination of reactions that are slowed by low gravity and temperatures will give scientists a deeper understanding of superconductivity.The study of materials science is an important ISS research activity, with the objective of reaping economic benefits through the improvement of techniques used on the ground. Other areas of interest include the effect of the low gravity environment on combustion, through the study of the efficiency of burning and control of emissions and pollutants. These findings may improve our knowledge about energy production, and lead to economic and environmental benefits. Future plans are for the researchers aboard the ISS to examine aerosols, ozone, water vapour, and oxides in Earth's atmosphere, as well as cosmic rays, cosmic dust, antimatter, and dark matter in the universe.

Shuttle Amateur Radio Experiment

The Shuttle Amateur Radio Experiment (SAREX), later called the Space Amateur Radio Experiment, was a program that promoted and supported the use of amateur ("ham") radio by astronauts in low earth orbit aboard the United States Space Shuttle to communicate with other amateur radio stations around the world. It was superseded by the Amateur Radio on the International Space Station (ARISS) program. SAREX was sponsored by NASA, AMSAT (The Radio Amateur Satellite Corporation), and the ARRL (American Radio Relay League).

Yi So-yeon

Yi So-yeon (born June 2, 1978) is an astronaut and biotechnologist who became the first Korean to fly in space. Upon return from her mission aboard the ISS, Yi continued as a KARI researcher attending the International Space University before retiring from the agency to pursue an MBA at the University of California, Berkeley Haas School of Business and joining commercial astronaut corps the Association of Spaceflight Professionals.
