Visitors to the Pioneer GrowingPoint(SM) website can now follow the growth and development of soybeans being grown in outer space this summer.

Soybeans from Pioneer Hi-Bred International, Inc., a DuPont subsidiary, were launched into orbit on the space shuttle Endeavor in June, and eight seeds of Pioneer® brand variety 9306 were planted inside a growth chamber which was transferred to the International Space Station. The experiment was initiated on June 11. Throughout the summer, Pioneer will be posting updated photos of the soybeans in space, along with information about their development.

In the first space experiment of its kind, DuPont partnered with the Wisconsin Center for Space Automation and Robotics (WCSAR) to conduct scientific research on one of the world's most consumed crops. Researchers will examine the effects of zero gravity on plant growth and development. Then, DuPont and WCSAR will study the harvested seed from the space-grown plants to find out if they have improved oil, protein, carbohydrates or other substances that could benefit farmers and consumers.

"The Pioneer GrowingPoint website is an outstanding information source in agriculture, and we wanted to provide the Soybeans in Space Update to our users as another way of keeping them directly informed of the work Pioneer's doing in the new frontiers of scientific research," said Bill Belzer, Pioneer e-business manager. "With this feature, users can observe this unique experiment through pictures taken at the international space station and follow the soybeans' progress along with the researchers."
