NASA officially retires its InSight Mars lander

After two consecutive failed attempts to re-establish contact, NASA on Wednesday officially called an end to its InSight Mars mission. On December 15th, the lander made its final transmission to Earth. NASA said it would make the tough decision to call the mission dead after two failed communication attempts earlier this year. The agency will continue to listen for a signal “just in case” but notes the odds of that occurring at this point are “considered unlikely.”
