SPACECRAFT: MARINER 6
Spacecraft Information
======================
Launch Date : 1969-02-24
Instrument Host Name : MARINER 6
Instrument Host Type : SPACECRAFT
Mission Information
===================
Mission Start Date : 1965-12-22
Mission Stop Date : UNK
Mission Alias Name : MARINER 6 & 7
Targets
=======
MARS
Instruments
===========
INFRARED SPECTROMETER
Spacecraft Description
======================
The Mariner 6 and 7 spacecraft were three- axis stabilized,
solar-powered, capable of providing continuous telemetry
transmission, and fully automatic, but commandable from
Earth when necessary. They each weighed 380 kg. The solar
panels provided 450 watts at Mars. The instrument payload
was 59 kg. Telemetry channels were available at data rates
between 8.33 and16200 bps. Both analog and digital tape
recorders were used; the former handled television data
only.
Platform Descriptions
=====================
Platform SCAN PLATFORM
----------------------
The Mariner 6 and 7 spacecraft used a two-axis scan
platform carrying the infrared radiometer, cameras, UV
spectrometer, and infrared spectrometer. It was used to
reposition the fields of view of the instruments repeatedly
during the Mars flyby.

SPACECRAFT: MARINER 9
Spacecraft Information
======================
Launch Date : 1971-05-30

IMAGING SCIENCE SUBSYSTEM
Spacecraft Description
======================
The design of Mariner Mars 1971 spacecraft was similar to
that of Mariner Mars 1969, but incorporated changes
required by the different payload complements, changes
required to increase reliability for a nominal transit
cruise and a 90-day-in-orbit operational lifetime, and
changes required for the spacecraft to accomplish the
mission. The spacecraft weighed approximately 2238 lbs; of
this weight 1050 lb was propellant required to correct the
transit trajectory and to perform the orbital insertion and
152 lb. which constituted the science payload. The
spacecraft configuration consisted of four solar panels, a
low-gain antenna, a maneuver engine, a Canopus sensor, two
propulsion tanks, two propulsion pressurization tanks,
temperature control louvers, four acquisition sun sensors,
a cruise sun sensor, a medium-gain antenna, a high-gain
antenna and a scan platform.
Platform Descriptions
=====================
Platform SCAN PLATFORM
----------------------
The scan platform was an articulating instrument mount
providing a pointing selection capability of 215 degrees in
azimuth and 69 degrees in elevation. The scan platform
contained the following instruments; the infrared
radiometer, the wide-angle TV, the ultraviolet
spectrometer, the narrow- angle TV and the IR
Interferometer spectrometer.
