On This Day In Space: Nov. 13, 1971: Mariner 9 becomes the 1st spacecraft to orbit Mars
Home News Spaceflight On Nov. 13, 1971, Mariner 9 became the first spacecraft to orbit Mars. At the time, scientists didn’t know much about the Red Planet. NASA had several Mars flybys before Mariner 9. Those flybys showed that Mars had a cratered surface, so some scientists thought that Mars looked just like the moon. Then
Sharks, turtles, disease on agenda of wildlife trade summit
Human demand for shark fin soup, particularly in East Asia, has threatened shark populations. The trade in shark fins, turtles, and other threatened species will come under scrutiny at a global wildlife summit in Panama, starting Monday, that will also focus on the spread of diseases such as COVID-19.

Physicist probes causes of life-shortening ‘dwell fatigue’ in titanium
STEM images of dislocation configurations after stress relaxation. The images show defect structures produced in Ti–7Al–0.05O and Ti–7Al–0.25O, in IWQ and aged conditions (550 °C for 49 d). STEM micrographs recorded for two-beam condition around B = {0111} as indicated. a In the low-oxygen, disordered material, dislocations are able to travel freely across a grain. Some dislocation
