Russia’s Mir Space Station has been in an integral part of human space flight.
Though it has suffered some serious, even life-threatening problems, Mir
continued to make strides in science and engineering until it was . Russian
cosmonauts and ground engineers have shown that humans can live and work in
space for extended periods of time. The information gained by the Mir Space
Station has been crucial to the development of the future International
Space Station.
The first element of the space station was the module Mir. It was launched
into orbit on February 20, 1986. Since then a number of different modules have
been added to the station to support a wide range of scientific endeavors. The
Mir module contains the main operations area for the station and living quarters
for the crew.
Kvant-1 was the first module added. It houses an astrophysics research lab.
Kvant-2 is the scientific research and airlock module. From Kvant-2 observations
of earth and biotechnology experiments are conducted and EVA’s (extravehicular
activities) are possible. The Kristal module has a Shuttle docking port,
contains a small greenhouse and semiconductor experiments. Spektr contains
atmospheric research and surface studies equipment. Priroda was the last module
added to Mir. Priroda houses a number of radiometers, spectrometers, and radar
for gathering data.
Two types of Russian spacecraft are used to transport crews and cargo to and
from the Mir. Soyuz-TM capsules deliver crew and cargo to the ship and can
safely return crews to earth. Progress-M spacecraft are used to resupply Mir and
bring up science experiments. Waste from the station can be loaded into
Progress-M ships and allowed to burn up in the Earth’s atmosphere.
Starting with Norm Thagard, Americans began to live and work aboard the Mir
Space Station. Thagard rode up to Mir with a Russian crew and spent 115 days on
orbit until the first Space Shuttle docked with Mir.
STS-71 signified a new era in space exploration for Americans. Norm Thagard
returned to Earth and a new Russian crew began their stay on Mir. Nine total
Space Shuttle flights docked with Mir as part of Phase I of the International
Space Station.
Shannon Lucid set a record for Americans in space with a 188 day stay on Mir.
Lucid was put aboard Mir by STS-76 (Atlantis) which launched on March 22, 1996.
She returned to Earth on September 26, 1996 with STS-79 (Atlantis). Lucid was
replace by John Blaha who remained aboard Mir for four months conducting
numerous science experiments.
Jerry Linenger replaced Blaha on Mir on January 12, 1996. He was the first
American to conduct space walk from a foreign space station. Linenger was also
present when the most severe fire ever reported in orbit occurred. Linenger and
his fellow cosmonauts reacted with the utmost professionalism and saved Mir from
a potentially deadly disaster. Linenger faced several more challenges including:
oxygen system failures, attitude control system problems and a near collision
with a resupply capsule. Despite the problems, all objectives of the mission
were completed and repairs made to the station.
May 17, 1997 Linenger was replaced by Michael Foale who also experienced a
number of problems on Mir. On June 25, 1997 a Progress resupply ship collided
with the Spektr module of the station. Pressure inside the module was lost and
Spektr had to be closed off to prevent pressure loss from the entire station.
Though much of Foale’s work was lost in Spektr, he continued to work with the
crew to maintain systems and conduct small experiments.
Foale was replaced on Mir by David Wolf on October September 28, 1997. Wolf
helped to restore many malfunctioning systems aboard Mir and conducted research.
The final American to live on Mir was Andrew Thomas. Thomas began his stay on
Mir on January 25, 1998 and after fulfilling a number of scientific projects was
returned to Earth on STS-91 (Atlantis) in June 1998.
Mir will soon be deactivated before the new International
Space Station is constructed. The exact timeframe for shutting down Mir is
still to be determined. When it is finally decommissioned, however, it will
leave behind a legacy of unparalleled accomplishment by the Russian Space
Agency.
