China’s Tianwen 1 spacecraft — in orbit around Mars since February — is scheduled to deploy a descent module to attempt the country’s first landing on the Red Planet in mid-May. Officials plan to share the Mars rover’s scientific data with researchers around the world, a senior Chinese scientist said last week.
