Also called:
International Sun-Earth
Explorer
Memorandum of Understanding
(MOU)
between NASA and European Space
Agency, Mar. 1975
Date of launch (range):
Oct. 22, 1977 (ETR)
Launch vehicle:
Thor-Delta 2914
Shape:
cylindrical (16-sided)
Weight (kg):
328.95
Dimensions (m):
1.73, diam.
1.61, height
Power source:
solar arrays plus AgCd battery
Prime contractor:
N/A

N/A
NASA's role:
spacecraft, launch vehicle, and
tracking and data acquisition
Responsible NASA center:
GSFC
Project manager:
Jeremiah J. Madden
Project scientist:
Keith W. Ogilvie
Objectives:
to increase our knowledge of
solar-terrestrial relationships by making detailed
measurements of the boundary regions that occur as a result
of the solar wind impinging on earth's magnetic field
environment, and to investigate the variations in these
boundaries with solar wind fluctuations (for use with ISSE
2).
Experiments (responsible country or
organization):
.
fast plasma (Los Alamos Scientific
Laboratories)
low-energy protons and electrons
(Univ. of Iowa)
fluxgate magnetometer (Univ. of
California, Los Angeles)
plasma waves (Univ. of Iowa)
plasma density (Paris
Observatory)
energetic electrons and protons
(National Oceanic and Atmospheric Administration)
electrons and protons (Univ. of
California)
fast electrons (GSFC)
low energy cosmic ray (Max Planck
Institut)
quasistatic electronic field (Univ.
of California)
DC electric field (GSFC)
ion composition (Lockheed Missiles
and Space Co.)
VLF wave propagation (Stanford
Univ.)
Results:
Results from all experiments were
obtained; data contributed to the International
Magnetospheric Study; a third ISEE satellite was launched in
1978; ISEE I and 2 were launched on a single Thor-Delta
vehicle.
