NOTICE: Because this page had grown so large (~168K), I have split it into 14 pages, including this page for mission acronyms beginning with I and J. Some direct, named links will no longer work. 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.
In the 1990's, up to 25 projects involving a total of 35 or so spacecraft from the four member space agencies will be either completely or partially dedicated to studying the solar-terrestrial environment.
For a general description, see the Reference Handbook for EOS.
The IKONOS 1 was lost April 27, 1999, apparently due to a problem with the Athena launch vechicle fairing. The second IKONOS successfully launched September 24, 1999 from Vandenberg Air Force Base, California. According to Space Imaging, Inc.'s Frequently Asked Questions web page, IKONOS is derived from the Greek word for "image," and according to the Earth Observation Magazine, the name is pronounced "Eye-KOH-nos."
IMAGE will be launched aboard a Delta 7326 in the year 2000. The IMAGE mission was selected for definition in (April or) May 1995 through the first MIDEX Announcement of Opportunity (AO).
Now renamed MI.
IMP-8, the last of ten IMP (Interplanetary Monitoring Platform) or AIMP (Anchored-IMP) spacecraft launched in 10 years, was launched by NASA on October 26, 1973, and continues to operate as of May 1996.
The Interball Tail Probe (also known as Prognoz-11) was succesfully launched on 3 August 1995 on a Molnia M launcher from Plesetsk. The Auroral Probe was successfully launched on 29 August 1996. The Interball project consists of two main satellites, the Tail Probe and the Auroral Probe, each with a MAGION subsatellite.
Some information is available under the MAGION subsatellite listing.
See Nanosat.
IRAS was launched in January of 1983.
I have found two IRIS missions.
Launched August 16, 1984, ended August 13, 1986. One of the three spacecraft in the AMPTE Mission.
IRS-1A was launched in March 1988, IRS-1B was launched in August 1991. IRS-1C is scheduled for launch in August or September of 1995. IRS-P is a planned series of smaller, single instrument remote-sensing spacecraft.
The Infrared Telescope in Space (IRTS), the first Japanese orbiting telescope dedicated to infrared astronomy, will be launched aboard Japan's Space Flyer Unit (SFU) on March 15, 1995 from Japan.
ISEE-A (NASA) launched _____, ISEE-B (ESA) launched in 1977. They operated together, so I think they were launched in the same year.
See also Alouette. Following the success of Canada's Alouette satellite launch in 1962, Canada and the United States signed an agreement to launch three satellites under a new program called International Satellites for Ionospheric Studies (ISIS).
ESA successfully launched the Infrared Space Observatory on November 16, 1995. They plan to operate it for at least 18 months.
NASA's GGS and COSTR Programs compromise the United States contribution to the ISTP science initiative.
Launched January 26, 1978 on a Thor-Delta rocket from Cape Kennedy. IUE real-time operations terminated on the September 27, 1996.
A proposal for a second generation space VLBI mission, the International VLBI Satellite, was made in response to an ESA call for new mission ideas in 1989. IVS was planned to have a much wider spectral coverage (4.5-8.5, 15-23, 42-63, 86-120 GHz, and possibly also 218-222 GHz bands), and a 20m class antenna.
Created September 19, 1996. Last update: September 6, 2000. Please see my Disclaimer and Web Policy page. Due to changing job assignments, I am not longer able to or responsible for maintaining these pages, but will try correct major problems when I can. Limited maintenance by Gordon Johnston:
