Je viens de trouver un document particulièrement intéressant. Il s'agit d'une monographie publiée par la Nasa et qui relève toutes les missions d'exploration du système solaire jusqu'en 2000 de toutes les agences spatiales. Il est au format PDF. Attention, il est divisé par chapitre, sachant qu'une année est égale à un chapitre, en tout et pour tout, je compte 45 fichiers avec l'introduction, la table des matières, les sources, petite bio de l'auteur entre autre.
A Chronology of Deep Space and Planetary Probes 1958–2000 (lien vers la table des matières)
On y trouve quoi? Et bien voici l'exemple d'une sonde japonaise destinée à étudier la comète de Halley. La dernière sonde enregistrée dans le document c'est Stardust... la 193ème.

[Sakigake]
Nation: Japan (1)
Objective(s): Halley’s Comet flyby
Spacecraft: MS-T5
Spacecraft Mass: 138.1 kg
Mission Design and Management: ISAS
Launch Vehicle: Mu-3S-II (no. 1)
Launch Date and Time: 7 January 1985 / 19:26 UT
Launch Site: Kagoshima / launch complex M1
Scientific Instruments:
1) solar wind ion detector
2) plasma wave probe
3) magnetometer
Results: The MS-T5 spacecraft (named
Sakigake after launch) was the first deep
space spacecraft launched by any country
apart from the Soviet Union and the United
States (the two German Helios probes had
been launched by NASA). Japan’s goal had
been to launch a single modest probe to fly
past Halley. As part of a test to prove out the
technologies and mission operations of the
actual mission, the country’s Institute of
Space and Astronautical Sciences (ISAS)
launched this test spacecraft known as MST5,
nearly identical to the “actual” vehicle
launched later. The spin-stabilized spacecraft
was launched by a new Japanese launch
vehicle, the Mu-3S-II. Following two course
corrections on 10 January and 14 February
1985, Sakigake was sent on a long-range
encounter (about 7.6 million kilometers) with
Halley. The spacecraft served as a reference
vehicle to permit scientists to eliminate
Earth atmospheric and ionospheric contributions
to the variations in Giotto’s transmissions
from within the coma. The spacecraft’s
closest approach to Halley was at 04:18 UT
on 11 March 1986, when it was 6.99 million
kilometers from the comet. Nearly six years
after the Halley encounter, Sakigake flew by
Earth on 8 January 1992 at a range of 88,790
kilometers. After two more distant flybys
through Earth’s magnetic tail (in June 1993
and July 1994), Sakigake maintained weekly
contact with the ground until telemetry was
lost on 15 November 1995, although the
ground continued to receive a beacon signal
until all contact was terminated on 7 January
1999.
