WEST LAFAYETTE, Ind. —
A video featuring Briony Horgan, an associate professor of planetary science in Purdue University’s College of Science and a tactical science lead with NASA, has been uploaded to the AP Video Hub.
In the video, she explains how the Perseverance rover mission on Mars has gone this year after it landed in February and its goals for the future.

STORYLINE:
Horgan helped NASA select Jezero Crater as the landing site for the mission and is part of the team that plans where the rover will go next. Horgan says that the mission’s first year has been a huge success and that the samples that scientists have gathered from Jezero Crater will help provide insight into the history of Mars. When the Perseverance rover first landed at Jezero, Horgan describes how the team discovered what looked to be sedimentary rocks in the area. After microscopic analysis, it turned out these rocks were not sedimentary, but igneous, left over from an ancient lava flow. Horgan says that these igneous rocks and others like them can be used to determine when Jezero Crater held liquid water and when it could have been habitable for life. These results can help researchers calculate when Mars was Earth-like. Horgan says that the mission’s second year will focus on the delta of Jezero Crater, which will hopefully give new insight into microbial life that may have lived at the bottom of an ancient lake.
