I have heard a little about it,
The mirror, about 100 feet in diameter, is a membrane covered with a metal layer that, in theory, would reflect sunlight onto some of the chilly
reaches of Russia during the long nights.
The mirror would serve as a prototype for larger models that may go up later, provided the cash-strapped space agency comes up with funds, said
Mission Control spokesman Valery Lyndin.
According to the plan, the folded membrane will be attached to the Progress cargo ship, which will dock with Mir on Tuesday. In February, the Progress
will unfold Znamya and the station's crew will guide the cargo ship using remote control to align the mirror.
The new mirror had been scheduled to be taken into orbit earlier this year, but the experiment was delayed due to a shortage in funds. The money
crunch that has afflicted the country for months also led to the postponement of the Progress launch, which had been originally planned for Oct. 15.
Along with the mirror, which weighs less than nine pounds, the cargo ship will deliver some regular cargo, including fuel, food, water, equipment and
other supplies to the Mir, Lyndin said.
