This is a rare opportunity to own a collection of 5 autographed photos of astronauts who have made significant contributions to the space industry, signed by the astronauts themselves, adding a personal touch to this unique set. These photos are perfect for collectors of space-related memorabilia and would make a great addition to any collection.

The photos are in excellent condition and have been well-preserved over the years. They come from a private collection in UT and have not been displayed publicly. Don't miss out on the chance to own a piece of history from the space industry. The STS-73 marked second flight of U.S. Microgravity Laboratory (USML) and built on foundation of its predecessor, which flew on Columbia during Mission STS-50 in 1992. Research during USML-2 concentrated within same overall areas of USML-1, with many experiments flying for second time.

Crew divided into two teams to work around the clock in 23-foot (seven-meter) long Spacelab module located in Columbia's payload bay. The other two missions ( STS-66 and STS-80 ) can be googled for more info
