An upcoming experiment aboard the International Space Station will test the effects of microgravity on living cells mixed with tiny ceramic particles. The test could result in powerful new antioxidants to treat the deleterious effects of prolonged exposure to space as well as various age-related diseases.

Astronauts on the International Space Station have completed 214 spacewalks in the past 21 years, but none have been all-women endeavours. So it was very exciting earlier this month when NASA publicized what was supposed to be the first all-female spacewalk in history.

China launched its Chang'e 4 lander and rover today from the Xichang Satellite Launch Center, as part of a mission that hopes to land on the far side of the Moon. Chang'e 4 is the next in the line of China's Chang'e missions, and would be the first craft to land on the Moon's far side. It demonstrates the competitiveness of the country's space program on the international scene.
