Does a sandwich on Mars taste different?
The answer could be no, according to new research that found long-term spaceflight exposure doesn’t change later generations of wheat seeds.
Molecular biologist Robert Ferl of the University of Florida and colleagues studied wheat seeds descended from plants that flew on the Russian Mir space station. The progenitor plants were in space for 167 days in 1991. When they were brought back to Earth, the plants gave rise to viable offspring seeds.
