Aboard the International Space Station (ISS), the Tissue Culture Medium (TCM) is the bioreactor vessel in which cell cultures are grown. With its two syringe ports, it is much like a bag used to administer intravenous fluid, except it allows gas exchange needed for life. The TCM contains cell culture medium, and when frozen cells are flown to the ISS, they are thawed and introduced to the TCM through the syringe ports. In the Cellular Biotechnology Operations Support System-Fluid Dynamics Investigation (CBOSS-FDI) experiment, several mixing procedures are being assessed to determine which method achieves the most uniform mixing of growing cells and culture medium.

Northeast Hellas Landscape

Bob Mccall and NASA Dryden Director Kevin Petersen stand by "Celebrating One Hundred Years of Powered Flight, 1903-2003", in the artist's studio in Paradise Valley, Arizona. The mural was created to celebrate the achievements of Wilbur and Orville Wright and to commemorate a century of powered flight. Many of the epic flights represented in the painting took place in the skies over NASA Dryden Flight Research Center. An equally important goal of this celebration will be to encourage the values that have characterized 100 years of aviation history: ingenuity, inventiveness, persistence, creativity and courage. These values hold true not just for pioneers of flight, but also for all pioneers of invention and innovation, and they will remain an important part of America's future. "Celebrating One Hundred Years of Powered Flight, 1903-2003", documents many significant achievements in aeronautics and space flight from the dawn of powered flight to the present. Historic aircraft and spacecraft serve as the backdrop, highlighting six figures representing the human element that made these milestones possible. These figures stand, symbolically supported by the words of Wilbur Wright, "It is my belief that flight is possible…" The quote was taken from a letter written to his father on September 3rd, 1900, announcing Wilbur's intention to make "some experiments with a flying machine" at Kitty Hawk, North Carolina. "This year, Bob is helping us commemorate the Centennial of Flight with a beautiful mural slated for placement in our Dryden Flight Research Center that documents the history of flight from the Wright Flyer to the International Space Station. We should all take note, I think, that in the grand scheme of things, one hundred years is a very short period of time. In that blink of an eye we've gone from Kitty Hawk to Tranquility Base and now look forward to our rovers traversing the surface of Mars. Despite the challenges we face, the future we envision, like the fu

Video images sent to the ground allow scientists to watch the behavior of the bubbles as they control the melting and freezing of the material during the Pore Formation and Mobility Investigation (PFMI) in the Microgravity Science Glovebox aboard the International Space Station. While the investigation studies the way that metals behave at the microscopic scale on Earth -- and how voids form -- the experiment uses a transparent material called succinonitrile that behaves like a metal to study this problem. The bubbles do not float to the top of the material in microgravity, so they can study their interactions.

VANDENBERG AFB, Calif. -- A Boeing Delta II rocket soars above the clouds here today at Vandenberg AFB, Calif. The NASA payloads aboard the rocket are the ICESat, an Ice Cloud and land Elevation Satellite, and CHIPSat, a Cosmic Hot Interstellar Plasma Spectrometer. ICESat, a 661-pound satellite, is a benchmark satellite for the Earth Observing System that will help scientists determine if the global sea level is rising or falling. It will observe the ice sheets that blanket the Earth’s poles to determine if they are growing or shrinking. It will assist in developing an understanding of how changes in the Earth’s atmosphere and climate affect polar ice masses and global sea level. The Geoscience Laser Altimeter System is the sole instrument on the satellite. CHIPSat, a suitcase-size 131-pound satellite, will provide information about the origin, physical processes and properties of the hot gas contained in the interstellar medium. This launch marks the first Delta from Vandenberg this year. (USAF photo by: SSgt. Lee A Osberry Jr.)

KENNEDY SPACE CENTER, Fla. - Mars Exploration Rover-1 is ready for prelaunch testing including deployment of the lander petals, the rover's solar arrays, camera mast and camera. While at KSC, each of the rovers, their aeroshells and landers will undergo a full mission simulation. After spin balance testing, each spacecraft will be mated to a solid propellant upper stage booster that will propel the spacecraft out of Earth orbit. Approximately 10 days before launch they will be transported to the launch pad for mating with their respective Boeing Delta II rockets. The rovers will serve as robotic geologists to seek answers about the evolution of Mars, particularly for a history of water. The rovers are identical to each other, and will land at different regions of Mars. Launch of the MER-1 is scheduled for May 30. MER-2 will follow June 25.
