Climate Disinformation on Facebook / Beyond the Headlines / Tracking Migratory Species from Space / Clean Energy in Space to Save Planet Earth / The Sirens of Mars

The Mars Perseverance Rover is set to leave Earth in late July or early August with the mission of helping to find out if there is evidence of past or present life on Mars. We'll talk with an astrobiologist who is part of the mission team and also the author of the new book, "Sirens of Mars".

Also, with an historic SpaceX launch and several Mars missions underway, 2020 is proving a pivotal year for space exploration. How innovations in space technology such as solar charging stations that beam energy back down to Earth, and mining hard rock materials in space, can be used to fight climate disruption.

Plus, the field of wildlife tracking is getting a major upgrade thanks to a new initiative called ICARUS. It uses special equipment on the International Space Station to allow researchers to track much smaller species than ever before, including tiny migrating birds and even insects.

And prominent environmental groups are joining more than 1000 companies in pausing their advertising on Facebook in July as part of the "Stop Hate for Profit" campaign. We talk about why these groups are taking a stand against the spread of racism, white supremacy and climate disinformation on this giant social media platform.
