The Last Days on Mars

In the 2040s, a Martian research base, Tantalus Base outpost, is established. The eight person crew, who have been stationed there for six months, is only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander. Mars scientist Marko Petrović has found samples that point to life on the planet. Without revealing his discovery, he devises a ruse for a last EVA on the surface. Crewmate Richard Harrington drives Petrović in a solar-powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, Petrović falls into a sinkhole that suddenly opens.
