In Today’s Deep Space Extra… International Space Station (ISS) experiments seek insight into health challenges for human deep space explorers. Intense solar activity may be headed toward Earth. Debris from Indian ASAT test still in orbit.

Human Space Exploration

Staying healthy longer in space

Phys.org (5/6): Rodent Research-12, an experiment now underway on board the International Space Station (ISS), is expected to offer insights into how the stresses of spaceflight affect the human immune system and what that may mean for future missions of deep space exploration. The immune systems of humans and mice are similar. The rodent subjects are being vaccinated before and while they are in space to assess how they respond.
