• STS -83 (1997)
• STS -94 (1997)

Gregory Thomas Linteris ( born October 4, 1957 in Demarest, New Jersey, USA ) is a former American astronaut.

Linteris 1979 received a bachelor's degree in chemical engineering from Princeton University in 1984 and a master's in mechanical engineering from Stanford University. In 1990 he received his doctorate in mechanical engineering, aviation and aerospace engineering at Princeton University.

Linteris worked as a researcher from 1985 to 1990 at Princeton University, and then to 1992 at the University of California in San Diego.

Since 1992 Linteris works as a mechanical engineer in the Materials and Product Group of the National Institute of Standards and Technology ( NIST).

STS -83

On 4 April 1997 Linteris launched as a payload specialist aboard the space shuttle Columbia into space. Payload was the Microgravity Science Laboratory ( MSL -1). Due to an issue with a fuel cell of the shuttle mission had to be shortened and the landing took place after nearly four days. NASA decided to repeat the mission three months later with the same crew.

STS -94

On 1 July 1997, the Columbia was launched again to the prematurely terminated the first attempt MSL - 1 mission. This time, the experiments in the Microgravity Science Laboratory could be carried out successfully. These included especially experiments to study the physical properties of the supercooled liquid mixtures and the combustion processes of solid and liquid materials, and for preparation of pure protein crystals.
