Last Shuttle Crammed with Science Experiments

When the final mission of the U.S. space shuttle program blasted off flawlessly on Friday, over one million onlookers gathered in Florida for the launch. Tens of millions more watched on television. But what they couldn’t see amid the liftoff fire and smoke was all the science that was en route to the International Space Station.

Space Shuttle Atlantis has a lot of experiments, including one from a Hawaiian biotech company called Tissue Genesis Incorporated. The company has been working with NASA for ten years to study the effects of microgravity on stem cells regenerated from fat tissue.

The research can be applied to fight vascular disease, improve heart bypass surgery and orthopedics.

Houston’s Odyssey Space Research put two Apple iPhones on the last shuttle mission, not so they can phone home from space but to conduct experiments using mobile applications.

Astronauts will use an app called SpaceLab. The experiment app was built to test iPhone cameras and gyroscopes as well as test the effects of radiation on the devices.

Others hope that iPhones will be able to replace some of the expensive and faulty navigation equipment that generally accompanies most space missions.

Besides biotech and high tech companies sending experiments into space the Student Spaceflight Experiments Program has sent a few projects as well.

A mini lab, about the size of a brick contains both professional and student science experiments. The Materials Dispersion Apparatus (MDA) houses about 90 different experiments, including 11 student experiments.

Ranging from yeast to tomatoes and from goldfish eggs to mouth bacteria student experiments will study the effects of microgravity by comparing samples on the ground to those that flew into space. Students will look for differences in cell structure, behavior or growth of their samples.

And though it is the last shuttle mission to the ISS, one experiment will perform a white-glove test of the space station to see if it is remaining biological clean after years of use. a state of the art lab on a chip will be able to detect biological and chemicals on any surface.

Another novel experiment comes from Arizona State University, where Cheryl Nickerson is working on developing next generation vaccines.

The microbiologist has been studying infection in microgravity and has already discovered that the salmonella bacteria becomes more virulent in zero-gravity.

She says, “Our earlier work showed the potential for spaceflight to provide novel insight into the mechanisms of microbial virulence that may lead to innovations in infectious disease control here on Earth.”

Now Nickerson and her colleague Roy Curtiss III, the director of the Biodesign Institute are hoping to find cures to hepatitis B, tuberculosis, cholera, typhoid fever, AIDS and pneumonia by enlisting the help of salmonella.

When the final flight of Atlantis returns she and Curtiss will examine their Recombinant Attenuated Salmonella Vaccine (RASV) payload to determine if microgravity makes the experimental vaccine that already proves powerful against pneumonia even stronger after going to outer space.
