National Aeronautics and Space Administration (NASA).....U.S., organization. Civilian Space Agency created by Congress. Founded in 1958, National Aeronautics and Space Administration (NASA) belongs to the executive branch of the Federal Government.

       NASA's mission to plan, direct, and conduct aeronautical and space activities is implemented by NASA Headquarters in Washington, D.C., and by ten major centers spread throughout the United States. Dozens of smaller facilities, from tracking antennas to Space Shuttle landing strips to telescopes are located around the world. The agency administers and maintains these facilities, builds and operates launch pads, trains astronauts, designs aircraft and spacecraft, and sends satellites into Earth orbit and beyond, and processes, analyzes, and distributes the resulting data and information. See NASA Centers.

       NASA shares responsibility for aviation and space activities with other federal agencies, including the Departments of Commerce, Transportation, and Defense. Much of the work on major projects such as the Space Shuttle and the Space Station is done in the private sector by aerospace companies under government contract.

       From its inception, NASA has been directed to pursue the expansion of human knowledge of phenomena in the atmosphere and space. NASA's programs of basic and applied research extend from microscopic sub-atomic particles to galactic astronomy. In addition to enhancing scientific knowledge, thousands of the technologies developed for aerospace have resulted in commercial applications.

       Science offices at NASA Headquarters carry out a wide range of research activities to fulfill NASA's science goals. Science offices within NASA are:

       Office of Mission to Planet Earth (MTPE) focuses on the "home planet" as a dynamic system of land, ocean, atmosphere, and life that can be investigated on a global scale from space using remote-sensing tools.

       Office of Life and Microgravity Sciences and Applications explores the basic physics of how solids, liquids, and gases behave in space; seeks an understanding of the basic mechanisms that underlie space adaptation-developing more effective countermeasures to mitigate the physiological effects of space flight; and studies the role of gravity on life.

       Office of Space Science includes the Space Physics and Astrophysics Division which studies the entire universe of stars and galaxies, including the sun. The Solar System Exploration division has launched spacecraft to all the known planets except Pluto in its quest to study the solar system.

Newton.....Unit of force, Newton [kgm/t2], unit of force = 1 kgm/s2 = 0.2248 pound-force.

NEWTON.....Europe, ESA, satellite, see XMM.

Newton's law of universal gravitation.....Orbit. All bodies attract each other with what is called gravitational attraction. This applies to the largest stars as well as the smallest particles of matter The force of attraction between two small bodies (or between two spherical bodies of any size) is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. In other words, the closer two bodies are to each other; the greater their mutual attraction. As a result, to stay in orbit, a satellite needs more speed in a low than a high orbit.

Newton's law of universal gravitation

Fg = (GM1M2)/R2

Fg = force due to gravity,

= [kgm/s2] or [N-m2/kg2]

G = universal gravitational constant, [m3/kgs2] or [N-m2/kg2]

M1, M2 = masses of the two bodies, [kg]

R = distance between the two bodies, [m]

       Kepler's three laws of planetary motion, which had been derived empirically by Johannes Kepler; were obtained with mathematical rigor as a consequence of Newton's law of universal gravitation in conjunction with his three laws of motion. See Kepler's three laws or motion.

Newton's laws of motion.....Newton's three laws of motion are which describes orbits:

       1. Every body continues in a state of uniform motion in a straight line unless acted upon by some external force. Introduces momentum with is the resistance of an object to a change in speed or direction, be it linear of angular.

Newton's 1st law of motion

p = MV

p = linear momentum

= [kgm/s]

M = mass [kg]

V = velocity [m/s]

Newton's 1st law of motion, in vector notation

p = MV

p = linear momentum vector

= [kgm/s]

M = mass [kg]

V = velocity vector [m/s]

Newton's 1st law of motion, For angular momentum;

H = IΛ

H = angular momentum vector

= [kgm2/s]

I = moment of intertia [kgm2]

Λ = angular velocity vector

= [rad/s]

Newton's 1st law of motion, for a moment arm


H = angular momentum vector

= [kgm2/s]

R = moment arm [m]

V = velocity vector [m/s]

M = mass. [kg]

       2. The time rate of change of momentum (mass x velocity) is proportional to the impressed force. In the usual case where the mass does not change, this law can be expressed in the familiar form:

       force = mass x acceleration = thrust.

Newton's 2nd law of motion

F = Ma

F = force [N]

M = mass [kg]

a = acceleration [m/s2}

Newton's 2nd law of motion in vector notation

F = (∂MV)/∂T

F = force vector [N]

M = mass [kg]

V = velocity vector [m/s]

T = time [s]

       3. To every force or action, there is always an equal and opposite reaction.

nimbus.....Latin for clouds.

NIMBUS.....U.S., satellite, meteorological. Originally was a weather forecasting program. Expanded to include scientific programs. 7 satellites were place in orbit between 1964 and 1978.

       Earth/atmospheric scientists, weather forecasters, the U.S. Weather Bureau and NASA, realizing the value of space-base observations of Earth, pushed for an improved TIROS. It would be named NIMBUS (Latin for rain cloud). But being an “improve TIROS” was not to be the fate of NIMBUS. The using community wanted more and better and higher resolution sensors, as yet undeveloped. So, in the early 1960's NIMBUS became NASA’s new technology test bed for Earth/atmospheric sensors. These new technologies would ultimately find their way onto newer satellites, e.g., ESSA, NOAA. 

       In general, the NIMBUS satellites carried sensors to measure the radiative properties of the Earth’s landmasses, oceans, and atmosphere. NIMBUS also carried instruments to improve surface mapping technologies, to develop new ground data processing techniques, to develop the capability to sense atmospheric variables in the vertical (soundings), and to develop improved satellite control.

       The first NIMBUS weighing in at 825 lbs. (376 kg), was launched on 28 August, 1964, from Vandenberg AFB, California, into a sun synchronous, polar orbit of 429 x 937 miles (686 x 1500 km) with a 98 minute period. The satellite carried:

- the Advanced Vidicon Camera System (AVCS) for higher resolution daylight coverage,

- the High Resolution Infrared Radiometer (HRIR) for nighttime and cloud-cover observation, and

- the Automatic Picture Transmission (APT) for delayed or direct readout to ground stations, which allowed pictures of local cloud conditions to be downloaded to inexpensive ground stations, i.e., special radios or fax machines.

The NIMBUS 1 satellites were much larger than TIROS, being 118 inches (3 meters) long, and 57 inches (1.4 meters) in diameter. When the solar cells were deployed, the satellite was 132 inches (4.4 meters) wide. NIMBUS 1 failed after one month in orbit. The only thing worse for the NIMBUS program was the failure of NIMBUS B, which was launched on 18 May, 1968, and crashed into the Pacific Ocean! (Hard to miss!) But part of NIMBUS B lived to fly again!

       The NIMBUS 2, was more successful, operating for more than two and one half years. The satellite carried and proved the value of:

- the AVCS, and

- both the new high and Medium Resolution Infrared Radiometer (MRIR) for improved nighttime cloud cover observation.

The radiometers were critical in providing data on the heat dynamics of the Earth’s atmosphere. This was essential for more accurate weather prediction. It also proved the value of a three axis stabilized satellite. The satellite did not revolve, rotate, or tumble in orbit, as earlier satellites did, thereby keeping the sensors pointed at the Earth at all times.

       The NIMBUS 3 was almost identical to NIMBUS B, and carried the same instrumentation as NIMBUS 2 plus the following:

- Infrared Inferometer Spectrometer (IRIS) to measure air pollution dispersion,

- a Satellite Infrared Spectrometer (SIRS) to measure water vapor and ozone dispersion in the atmosphere,

- Interrogation Recording and Location System (IRLS) to locate and identify transmissions from buoys, balloons and other small weather stations including the movement of an appropriately instrumented elk in Yellowstone National Park,

- an Image Dissector Camera (IDC) that replaced the AVCS, and

- a Monitor for Ultraviolet Solar Energy (MUSE).

NIMBUS 3 was the first U.S. satellite to measure day and night time temperature of the atmosphere at various altitudes. It also carried a SNAP-19 experimental radioactive isotope, Plutonium 238 powered electrical generator, which had been on the NIMBUS B, and recovered from the NIMBUS B crash site in the Pacific Ocean. The SNAP-19 provided supplemental power when NIMBUS solar cells were not illuminated by the sun. Previous satellites used batteries.

       NIMBUS 4 was similar to NIMBUS 3, but had the following added:

- A Backscatter Ultraviolet Spectrometer (BUS), which measured the UV scattered back into space from Earth, and

- a Temperature, Humidity and Infrared Radiometer (THIR), which measured the temperature, humidity and infrared properties, plus other instrumentation.

       NIMBUS 5 did not have the SNAP-19 power supply, but relied on batteries to provide the power when out of the sun’s light, and carried similar instrumentation to NIMBUS 4. NIMBUS 6 was similar to NIMBUS 5.

       NIMBUS 7, weighing in at 2171 lbs. (986 kgs), was launched on 24 October, 1987, into a circular 944 mile (1510 km) polar sun synchronous orbits, 104 minute period, and was similar to NIMBUS 5 plus it carried:

- the Total Ozone Mapping Spectrometer (TOMS), which mapped the Ozone hole and Sulfur dioxide (SO2) emission including those emanating from volcanos, and

- APT.

       The NIMBUS satellites grew from 830 lbs. to more than 2100 lbs. (377 to 954 kgs) to accommodate more instruments and equipment, and were all built by General Electric. The NIMBUS satellites were able to photograph 70% of the Earth each day and provided new technology and instrumentation for future ESSA, ITOS, TIROS N, and NOAA satellite.

Noa.....USS Noa DD-841, recovery ship, part of the fleet which recovered or was on duty and capable of recovering the following: GEMINI AGENA 6, GEMINI 8. Prime recovery ship for MERCURY-GLENN.

NOAA.....U.S., satellite, weather. Derived from the TIROS satellites. National Oceanographic and Atmospheric Administration, part of the U.S. Department of Commerce. Originally named ITOS. The satellite is given a letter designation until successfully in orbit, then it is given a number designation.

       Starting in the early 1970's, the weather satellites were being named NOAA. Depending on the documentation, the satellites could have the ITOS or NOAA designation, or both. In 1979, the designation for weather satellites under construction became NOAA, starting with NOAA A which became NOAA 6. The ITOS designation was not used after NOAA 5, ITOS H.

       The next big change came with NOAA 6, built by RCA, which was based upon the TIROS N experimental satellite. Its mission and those of all the future NOAA satellites, was to provide continuous coverage of Earth and provide high-resolution global meteorological data. The satellite was 74 inches (1.88 m) in diameter, 146 inches (3.7 m) long, and carried the following instrumentation:

- Advanced very high resolution radiometer (AVHRR) for measuring day and night sea surface temperature, ice, snow and cloud conditions,

- atmospheric sounding system (ASS), also known as (TOVS - TIROS Operational Vertical Sounder) which provided vertical profiles of temperature and water vapor from the Earth's surface to the top of the atmosphere. and

- space environmental monitor (SEM) to measure energetic particles from the sun for solar storm predictions.

- Data collection platform to receive, process, ans store information from free floating balloons and buoys worldwide for transmission to one central processing facility.

NOAA 6, weight was increased to 1600 lbs (750 kg)*, and required the use of a larger launch vehicle, the Atlas F. The orbit was lowered to 540 miles (800 km) and orbital period was 101 minutes. NOAA B and NOAA 7 were very similar to NOAA 6. NOAA b was unstable in orbit and never became operational.

       NOAA 8 size was increased to 166 inches (4.2 m) long ( diameter remained unchanged), and weight increased to 2000 lbs (900 kgs)*. Requiring the use of an Atlas E launch vehicle. NOAA 8 also carried the Search and Rescue Aided Tracking system (SARSAT), which has the capability of detect distress signals from aviators, mariners and land travelers within 4.5 to 9 miles (8 to 16 km). This system helped rescues by the U.S. Air Force and Coast Guard.

       NOAA 9 was similar to NOAA 8, but carried:

- Earth Radiation Budget Experiment (ERBE) which studied the Earth’s albedo in an attempt to recognize and interpret seasonal and annual climate variations.

- Solar Backscatter Ultraviolet (SBUV) which measured the vertical structure of ozone in the atmosphere.

       NOAA 10 was similar to NOAA 9 but did not carry the SBUV. NOAA 11 was similar to NOAA 9. NOAA 12 was similar to NOAA 8 but did not carry the SARSAT. NOAA 12 was the last satellite built by RCA, which would eventually be part of Lockheed Martin. NOAA 13 was similar to NOAA 9 but the weight was increased to 2200 lbs. Unfortunately , the satellite operated for only 12 days, when it lost power, and was never considered operational. NOAA 14 which continues to operate, was similar to NOAA 13.  

       NOAA 15 was an improvement over the TIROS N series (NOAA 6-14). The instrumentation incorporated improvements over that in NOAA 14, and had additional instrumentation for the generation of temperature, moisture and surface hydrological products including regions which where visible to infrared instruments. The satellites starting with NOAA 15, were considered Advanced Television Infrared Operational satellites Next Generation (ATN). NOAA 16 and NOAA 17 are similar to NOAA 15. The lifetimes of these satellites are expected to be greater than 2 years. One interesting fact is that newest NOAA satellites were launched with one of the U.S. oldest launch vehicles, a Titan 23G, which is a refurbished Titan II ICBM dating back to the late 1960's. The launch vehicle is probably older than some of the people building and launching the NOAA satellites.

       As of August, 2002, NOAA 11, 12, 14, 15, 16, & 17 were functioning and used by NOAA to provide weather forecast.

* Weight uncertain, could be launch weight which may include a third stage rocket motor, which is part of the satellite, for injection into a SSO (at launch), or it could be the weight of the satellite once in the proper orbit after the fuel has been expended (known as on-orbit weight). The references are not clear! Some documents list NOAA 6 weight as 3000 lbs (1360 kgs) (at launch) and 1600 lbs (727 kgs) (in SSO).
