“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species. Abigail Allwood’s Hunt for Alien Fossils on Mars Has Begun, reports Isaac Schultz for Gizmodo –When the NASA Mars rover Perseverance was dramatically airlifted through the Red Planet’s atmosphere and touched down on the iron-rich soil, geologist and astrobiologist Abigail Allwood was at home on Earth, watching the events unfold via livestream like the rest of us.
