Cancelled satellite programmes...
Satellites programmes appear in these pages first as 'future' or planned
missions, and then progress to the yearly mission listings. Cancelled programmes are
collected in this page as the information is often still useful, but also as a tribute to those who have spent significant effort on these
missions.
 NISSE - NISSE, A Norwegian mission to study ion outflow from the atmosphere and ionosphere. The
satellite would have a mass of 89kg and 31W orbital average power. Telemetry rate would be
1.6kbps.
 HUTSAT - HUTSAT is a 45kg, 450mm
cubical microsatellite being designed at the Technical University of Helsinki in Finland.
The main mission objectives are in educational and scientific research. It will include a
particle detector and provide amateur satellite communications.
- FS-1
- FS-1 , a study for TEKES (The
Technology Development Centre of Finland) of a small Finnish satellite with applications
in Earth Observation and Space science.

1995
GEMSTAR
- A proposed small satellite communication constellation, abandoned after the first launch
failure of the first satellite in 1995.
1997
GE Starsys (former Starsys Global Positioning Inc.)
- A proposed system of up to 24 satellites in 4 planes at 60degrees and 1067km altitude,
offering asset tracking, monitoring and location. GE American Communications bought a
major stake in starsys global positioning inc. in 1996, and set up the GE Starsys company.
The system was expected to cost $170m (1996) for the first six satellites, 6 years of
operations and the ground system. The S80/T microsatellite demonstrator was launched in
1992.
-
- Alcatel was awarded a contract for the satellites soon after the formation of GE
Starsys, and was to building the 70kg satellites. Under an MOU with Matra Marconi, the
satellite structure (LEOSTAR bus) will be delivered to Alcatel. The first satellite was to
be delivered to Alcatel in June 1998, and the first two satellites were to be launched in
November 1998 (LMLV?), and a further two in January 1999. The PDR for the satellites was
held in early 1997.
-
- The ground segment was not yet designed, but the plan was for two-way messaging using 80
character alphanumeric messages. The WARC-92 VHF and UHF frequency bands were to be used.
-
- An FCC licence was received in the first round of applications, and additional spectrum
was applied for in the second round.
-
- The FCC licence was returned to the FCC in late 1997. More...
[S80/T]
-
- Clementine
II
- A follow on to the successful Clementine-I lunar mission, was
to be lead by Phillips lab with bus construction
at the Naval Research lab. The funding for this mission has not been made available as it
was vetoed by Pres. Clinton on the 14th October 1997.
1998
- Clark
- Clark is a NASA SSTI spacecraft first awarded to CTA Inc under a US$49m contract, later
taken over by OSC. It is named after Lieutenant William Clark, an American pioneer
explorer. The satellite was to demonstrate more than 36 new space technologies, including
a 3m and 15m resolution Multi Spectral Imager, as well as various science payloads. The
imaging payload is the same as that for EarthWatch, and secondary payloads include an
atmospheric pollution sensor, and an atmospheric temperature sensor to be used in
conjunction with ground based lasers. The 284kg minisatellite was to be launched into a
478km sun-synchronous orbit (11:15) in late 1998 on an Athena-1 at a total cost of about
$55M including launch.
-
- Having been taken over by OSC in 1997, In February 1998 the satellite construction was
stopped after a 15% overspend and 2 year delay on the project. The companion mission
'Lewis' suffered an early in-orbit failure. More...

- Lunarsat
- A 100kg lunar mission proposed to ESA by a consortium of Universities and Industry,
including SSTL, Technical University of Münich and Institute of Space Physics in Sweden.
The main aim of the mission will be education and Outreach, and to investigate the fitness
of the South Polar lunar region for the first human outpost. One of the payloads will be a
multispectral camera for illumination mapping.

2000
- ESAT
1-6,
2001
- The first three of six satellites in the "little LEO" E-SAT constellation will
be launched together on a Rockot marketed by the Eurockot Russian-German joint venture
"Eurockot", originally planned for late
1998, now likely for early 2001. The final set of three satellites will be launched six
months later. The system is being proposed by DBSI
and Echostar in the US, and received an FCC licence in early 1998. The satellites will be
built by SSTL (UK) and the payload will be integrated by Alcatel (Fr). The system is
intended to provide remote utility meter readings.
