Roger Wiens is a planetary scientist and Fellow at ‪@LosAlamosNationalLab‬. He is the principal investigator for both the ChemCam instrument aboard the Mars Curiosity rover and the SuperCam instrument, aboard the Perseverance rover. The SuperCam on NASA's Perseverance rover examines rocks and soils with a camera, laser and spectrometers to seek organic compounds that could be related to past life on Mars. It can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (7 meters)

Anders Johansen is a Professor of Astronomy at Lund Observatory at Lund University in Sweden, working there on topics such as planet formation, accretion discs, turbulence, and supercomputing. He obtained his PhD in 2007 at Max Planck Institute for Astronomy in Heidelberg. After that he spent a bit more than two years as a postdoc at Leiden Observatory. Anders obtained his docent degree from Lund University in 2013. According to a study led by ProfessorJohansen, Earth, Venus and Mars were created from small dust particles containing ice and carbon. The discovery opens up the possibility that the Milky Way may be filled with aquatic planets.
