NASA’s mega-project of scooping up and transferring specimens of Mars to our planet is under intense scrutiny and has been put on pause.
The plan, which never looked easy, called for a NASA-built Sample Return Lander (SRL) housing a Mars Ascent Vehicle (MAV) and a robotic arm provided by the European Space Agency.
