NOTICE: Because this page had grown so large (~168K), I have split it into 14 pages, including this page for acronyms that begin with M and N. Some direct, named links will no longer work. If you are looking for information about a particular mission, please select the appropriate file from the following alphabetical listing. If you cannot find information on the mission you are looking for, you may find some information in the "Pages with Information on Many Missions" section of the General Information page.
NASA Venus Radar Mapping Mission, launched May 4, 1989, arrived at Venus on August 10, 1990. Magellan's orbit decayed to the point where it entered the Venusian atmosphere on October 12, 1994, and was crushed by the pressure of Venus's atmosphere. Magellan's signal was lost at 10:02 Universal Time (3:02 a.m. Pacific Daylight Time) that day.
MAGION is a name of the serial of small MAGnetospheric and IONospheric satellites manufactured in Czech Republic to be launched as Russian scientific S/C hitch-hikers.

The Mars Climate Orbiter was launched from Cape Canaveral Air Force Station (CCAFS) Space Launch Complex 17 (SLC-17) on December 11, 1998 by a Boeing Delta II 7425 launch vehicle. MCO was lost September 23, 1999, due to a navigation error.
The Mercury project, the United States' first manned space flight project, included a total of 25 flights, 6 of them manned, from August 1959 to May 1963.
With the loss of MO, the plans for MESUR have been replaced by the Mars Global Surveyor (MGS).
There appear to be US and Russian spacecraft named METEOR.
Meteor-3 and NASA's Total Ozone Mapping Spectrometer (TOMS). A Total Ozone Mapping Spectrometer (TOMS) was launched aboard a Russian rocket (Cyclone) and spacecraft (Meteor-3) on August 15, 1991 from Plesetsk, Russia. It stopped producing useful data on December 27, 1994. Work is ongoing to recover the experiment.
The METEOR spacecraft was destroyed in a Conestoga launch failure on October 23, 1995.

Launched November 7, 1996.
Previously known as IMI.
MicroLab-1 was launched April 3, 1995 on an Orbital Sciences Corp. Pegasus launch vehicle. MicroLab-1 carries two instruments in its payload, an Optical Transient Detector developed by NASA's Marshall Space Flight Center, and the GPS Meteorological Experiment sponsored by the National Science Foundation. ORBIMAGE now uses the name OrbView-1.

The IMAGE and MAP missions were selected for definition in (April or) May 1995 through the first MIDEX Announcement of Opportunity (AO). In addition to IMAGE and MAP, the HESSI and HUBE missions were selected as possible alternates. See also Explorer.
The first Spanish satellite MINISAT 01 launched April 21, 1997 on a Pegasus XL over the Canary Islands (Spain). Orbital's L-1011 aircraft departed from Gando Air Force Base in the Canary Islands at approximately 7:00 a.m. E.D.T. (1100 G.M.T.) and flew to a predetermined location at 39,000 feet over the Atlantic Ocean, where the Pegasus XL rocket was released at approximately 7:59 a.m. E.D.T. (1159 G.M.T.). After an approximate 10 minute and 45 second flight, Pegasus deployed MINISAT into its proper orbit of approximately 570 by 577 kilometers, inclined at 151 degrees to the equator. Pegasus also carried a small payload from Celestis, Inc., which was also placed into its planned orbit.
Mir means peace in Russian. Mir is the Russian Space Station that is now nine years old.
Mars Observer was launched on September 25, 1992, aboard a Titan III launch vehicle from Cape Canaveral Air Force Station in Florida. Mars Observer had completed an 11-month, 711-million-kilometer (442-million-mile) journey to Mars and was within three days of entering orbit around the planet when it fell silent at about 1:00 Universal Time on August 22, 1993 (6 p.m. Pacific Daylight Time on August 21).

NOAA assigns a letter to the satellite before it is launched, and a number once it has achieved orbit. For example, NOAA-11, now in orbit, was designated NOAA-H before launch.
Currently, NOAA is operating two polar orbiters (also know as TIROS or POES): NOAA-11, launched in September 1988, and NOAA-12, launched in May 1991. NOAA-14 was launched on December 30, 1994.

As recommended by Vice President Gore's National Performance Review, the US is combining its military and civilian weather satellite programs (expected to save American taxpayers up to $300 million through 1999, with additional savings through the life of the program). The first satellite under the new system, called the National Polar-orbiting Operational Environmental Satellite System (NPOESS), is expected to be launched in 2006. To acquire and operate the NPOESS, the Department of Defense, NASA and NOAA have established an Integrated Program Office (IPO).

Deployed from STS-51B in April/May 1985.
Created September 19, 1996. Last update: April 21, 1997 (additional, minor updates as late as September 6, 2000). Due to changing job assignments, I no longer actively maintain this page, and no one has taken over. I will continue to update and correct problems on a best effort basis.
