NASA's research plans aboard the International Space Station (ISS) are discussed. Experiments in low temperature physics and atomic physics are planned to commence in late 2005. Experiments in gravitational physics are planned to begin in 2007. A low temperature microgravity physics facility is under development for the low temperature and gravitation experiments.

This paper presents a new technology program, within the fundamental physics research program, focusing on four quantum technology areas: quantum atomics, quantum optics, space superconductivity and quantum sensor technology, and quantum fluid based sensor and modeling technology.
Presentation on the transition in 4He in the presence of a heat current (Q) provides an ideal system for the study of phase transitions under non-equlibrium, dynamical conditions. Many physical properties become nonlinear and Q-dependant near the transition temperature, T_Lambada.
The Low Temperature Microgravity Physics Facility (LTMPF) is a state of the art facility for conducting fundamental research in a microgravity environment at low temperatures.
In 1998, about 100 researchers met twice to develop plans for the future in this research area. The results of these meetings have been collected in a package titled: A Roadmap for Fundamental Physics in Space. A summary of the Roadmap will be presented along with an overview of the current program.

The Low Temperature Platform Facility (LTPF) flew on STS-87 from November 19 to December 5, 1997 as part of the fourth United States Microgravity Payload (USMP-4).
Gravity obscures some of the most subtle phenomena that are key to solving outstanding questions in physics today.
We report on our latest measurements of gravity reduction in the low-gravity simulator. We made these measurements using a new thermal conductivity cell design that is 0.5cm in diameter and 0.5cm in height.

We have performed numerical simulations of the behavior in a one-dimensional thermal conductivity cell of helium as it is ramped through the superfluid transition from below.
