SPARTAN 201: NASA's mission to explore the Sun's corona
A composite image of the solar corona on 1993 April 11 from SPARTAN 201-1
White Light Coronagraph (outermost), the High Altitude Observatory Mk. III
coronagraph on Mauna Loa, Hawaii (middle), and the Yohkoh
Soft X-Ray Telescope (innermost image)

These pages include images downlinked in near realtime
from the white light coronagraph, as part of the
technology demonstration of SPARTAN realtime telemetry.
|SPARTAN 201-4 grappled by STS-87 astronauts
The United States Space Shuttle
Columbia (OV-102) was not able to deploy
SPARTAN 201-04, a small shuttle-launched and -retrieved satellite, whose
mission is to study the origins of the solar wind, on 1997 November 21 during
Shuttle mission STS-87.
The two instruments of SPARTAN 201, the
Ultraviolet Coronal Spectrometer and the
White Light Coronagraph.
SPARTAN 201 has flown on three previous missions:
The 1994 September observations were coordinated with observations made by the
Ulysses spacecraft and
other space- and ground-based observatories. The SPARTAN 201-4 flight will be
coordinated with observations made from the
Solar and Heliospheric Observatory
(SOHO) , a mission of international cooperation between the
European Space Agency (ESA) and NASA. In particular, the SPARTAN
UVCS will be used to
determine the instrumental profile of the H I Lyman alpha line for the
- SPARTAN 201-1 on Mission
STS-56 (1993 April)
- SPARTAN 201-2 on Mission
STS-64 (1994 September)
- SPARTAN 201-3 on Mission
STS-69 (1995 September)
This work will require relatively long periods with fixed pointing, during
which the SPARTAN
White Light Coronagraph and the SOHO
LASCO coronagraphs will
search for short time-scale variability in electron-scattering corona.
