TIROS.....U.S. NASA, ESSA, NOAA, satellite, meteorological. TELEVISION INFRARED OBSERVATION SATELLITE, 24 hour television infrared weather monitoring systems.

The story of TIROS begins with studies done in the late 1940's and early 1950's, both classified and unclassified, that discussed the feasibility of satellites observing the Earth’s weather, also known as meteorological satellites. The first public mention by the U.S. Weather Bureau, was a paper by H. Wexler in 1954. Tests’ by sounding rockets convinced most weather experts of the value of space-based weather observations, supporting the contention that “You can see a lot, by looking!” (Yes, Yogi Berra said this). Support languished until two events occurred: A) in March 1955, the USAF issued a secret directive to develop a reconnaissance program, including weather observation, leading to the WS-117L program, and B) President Eisenhower on 5 July, 1955, announced the United States would launch scientific satellites in support of the International Geophysical Year. The nascent satellite community smelled money. The Naval Research Laboratory in Washington, D.C., proposed a satellite, that would include technology experiments and the data collection necessary for the development of weather satellites. This ultimately became the VANGUARD satellite.

       At the same time, both the other branches of the military and the U.S. Weather Bureau were developing plans and studies for weather satellites. After SPUTNIK was launched, the impetus for U.S. satellite development greatly accelerated (Thank you, Russia). At that time, most work on weather satellites came under the purview of the Department of Defense Advanced Research Projects Agency (ARPA). APRA received input from the military services and the U.S. Weather Service, and subsequently gave the responsibility for developing a weather satellite to the U.S. Army Signal Research and Development Laboratory (USASRDL), Fort Monmouth, New Jersey, which was familiar with satellite and tracking technology and went on to develop other satellites. One can only imagine the politicking and lobbying that took place, but that is another story. The Weather Service and the Army had a long history together, the weather Service started in the Army Signal Service, in 1870, and remained there until the weather service was transferred to the Department of Agriculture and became the US Weather Bureau, on 1 July, 1890.

       During 1955, the Radio Corporation of American (RCA), who had been working under the WS-117L program to develop television equipped spy satellites, entered the picture. The WS-117L program had chosen to use photographic technology in lieu of television for picture taking for the spy satellites, giving birth the DISCOVERER/CORONA satellites, which was a great disappointment for RCA. Not to be left out of the potential satellite market, RCA proposed the use of television cameras for weather satellites. The contract was awarded to RCA, and the Janus program was created and given to the USASRDL in 1956.

       After studying several satellite configurations, the USASRDL chose the drum shape. It seems that the “EXPLORER” rod shape had a tendency to tumble unstably in orbit. The rotating drum shape was more stable, making it more suitable for taking television pictures of Earth from space. The name of the program was changed from Janus to TIROS (Television and InfraRed Observation Satellite). 

       The mission of TIROS was to provide an operating system for daily worldwide weather observations using proven remote sensing technologies, thus inaugurating space-based meteorology.

       During this same time period, 1955-60, intense competition for use of launch vehicles was underway by the military branches and launch vehicle manufacturers. The competition continues today on an international scale, but that’s another story. The Army, Navy, and Air Force proposed and developed their own launch vehicles based upon the IRBMs and ICBMs in their arsenal. That fierce competition is the subject of many more stories. The Thor-Able launch vehicle was chosen and the USAF took control of the TIROS program in 1958. One can only imagine the feeling of the US Army in losing it to the Air Force. However, the Air Force was to experience a similar feeling, when in 1959, President Eisenhower transferred control of the TIROS program to a brand new civilian agency, the National Aeronautics and Space Administration (NASA). The U.S. Department of Defense was not to be without a weather satellite, and this story will be told through the DMSP satellite program.

       The TIROS design continued under the direction of the NASA’s Goddard Space Flight Center, Greenbelt, Maryland, one of several facilities funded by NASA, through 1959. The first TIROS satellite was a squat cylinder, 42 inches (1.07 meters) in diameter and 19 inches (0.49 meters) tall. The two RCA television (TV) cameras viewed the Earth through the base plate. Around the circumference were mounted solar cells to power the satellite. The satellite “flew” through space similar to a frisbee. The satellite was spin stabilized, like a spinning top, and used the Earths magnetic field to turn the satellite in order for the cameras to continually face the surface of the Earth.

       The two television cameras had 500 line resolution, similar to your conventional television set in the U.S. One camera was equipped with a wide angle lense, f 1.5, providing a 600,000 square mile (1.6 million square km) image. The other camera was equipped with a narrow angle lens, f 1.8, providing a 5,000 square mile (13,000 square km) image. The orbital altitude was 460 miles (740 km). The combination of optics and orbital altitude allowed the satellite pictures to be contiguous, the earth rotated just enough during the 95 minute orbits for the left-hand edge of one picture to match the right-hand edge of the picture taken 95 minutes later. This was optimized to occur over the northern hemisphere land masses.

       The images were transmitted directly to ground stations when in range, or stored on a tape recorder and sent when the satellite passed over the ground station. Two existing ground stations were used for Command and Data Acquisition (CDA), the US Army Signal Corps laboratory in Belmar, New Jersey, and the U.S. Air Force facility a Kaena Point, Hawaii. A third station, located at the RCA plant in Hightstown, New Jersey, where the TIROS were built, served as a backup and for engineering. The data were then sent to U.S. Weather Bureau National Meteorological Center (NMC) near Washington, D.C. The TIROS program followed the organization plan were RCA builds the TIROS, NASA managed the project, and the U.S. Weather Bureau analyzed the meteorological data and provided weather forecasts.

       The first TIROS flown satellite was designated as A-1, and contained the two television cameras. No other instrumentation was included to keep the cost and complexity down. Later TIROS satellites carried infrared radiometers (IR). The first TIROS was launched on 1 April, 1960, by the last Thor Able launch vehicle. (See Figure 2-1, An early TIROS satellite - later models had cameras mounted on sides(NOAA Photograph)). The 263 lbs. (119 kg) satellite was placed in a 430 by 466 mile (690 by 750 km) orbit, at a 48.4 degree inclination. The only problem was the malfunction of the narrow angle television camera control system. However, after 1 month in orbit, it began to operate (Romulan interference in our space program?). TIROS operated for 77 days until a fatal power failure. The satellite returned 22,952 pictures of the Earths weather system’s, including pictures of the USSR and China. The pictures were distributed worldwide for everyones use. This must have given the USSR and China mixed feeling, having a foreign power take pictures of their country’s land mass and their weather, but also allowed the USSR and China to provide improved weather predictions for their countries.

       TIROS 1 success spurred the continued support and technological improvements, with newer, more complex, and heavier satellites (270-305 lbs., 122-138 kg) with longer lifetimes. The additional instrumentation enabled the satellites to collect data that improved the U.S. Weather Service’s ability to forecast the weather. Improvements resulted in TIROS 7 operating for 1809 days, the longest of any TIROS satellite. All the TIROS through TIROS 7 were launched with an inclination of 58 degrees or less. The next big change came with the launch of TIROS 9. This satellite was placed in a near polar orbit (inclination of about 90 degrees) even though it was launched from Cape Canaveral, Florida. The satellite could now view the entire Earth. The orbit and altitude were also chosen for their sun-synchronous properties. That is, the satellite passed over the same spot on the surface of the Earth at the same time of day, allowing comparisons from day to day, which is a great advantage in weather forecasting (and intelligence gathering). Now you know that the lens optics, orbit altitude, orbital period, and inclination are all interrelated it give the desired viewing coverage. TIROS 9 also had the television cameras mounted around the circumference, and the satellite rolled around its orbit similar to the rolling of a tire, with the cameras pointing toward the Earth then into space. TIROS 10 was similar to TIROS 7.

       Now jump forward 13 years to 1978, and we have TIROS N, Television Infrared Operational satellite’s Next Generation. The satellite weighed more than 1600 lbs., was 146 inches long by 74 inches wide, and included the AVHRR, TOVS-TIROS, and a data collection platforms used to receive, process, and store information from free floating balloons and buoys worldwide. It was placed in a 470 nm polar orbit, Earth oriented with three-axis stabilization. The TIROS N was the prototype for the new NOAA satellites launched from 1979.

       During this time, the designation of the TIROS satellite numbering protocol was put in place. With the exception of the first TIROS satellite, the satellite was given a name and letter designation during design, construction and launch (e.g., TIROS C). It is possible for a satellite to have more than one designation during this phase of its life (e.g., TIROS C was also known as A-3). The designations may not be in numerical or alphabetical sequence, e.g., TIROS D is also known as A-9. (I do not know what happened to A-4 through A-8.) After being successfully placed in orbit and functioning, the satellites name was changed to a number (e.g., TIROS C was changed to TIROS 3). If a satellite was lost or did not function correctly, it would not receive the number designation. This system continues to be use today.

TWINS.....U.S., NASA, satellite, scientific, LEO : Selected as a mission of opportunity, the $15 million TWO WIDE-ANGLE IMAGING NEUTRAL-ATOM SPECTROMETERS (TWINS) satellites will be launched in 2001 or 2003 aboard a currently undesignated U.S. Government mission. TWINS will provide stereo imaging of the Earth's magnetosphere, the region surrounding the planet controlled by its magnetic field and containing the Van Allen radiation belts and other energetic charged particles. TWINS will enable 3 dimensional global visualization of this region, which will lead to greatly enhanced understanding of the connections between different regions of the magnetosphere and their relation to the solar wind. The TWINS satellite mission provides a new capability for stereoscopically imaging the magnetosphere. By imaging the charge exchange neutral atoms over a broad energy range (~1-100 keV) using two identical instruments on two widely spaced high-altitude, high-inclination spacecraft, TWINS will enable the 3-dimensional visualization and the resolution of large scale structures and dynamics within the magnetosphere for the first time.
