Perseverance: Nasa rover begins key drive to find life on Mars
Nasa's Perseverance rover has reached a big moment in its mission on Mars. Tuesday, the six-wheeled robot began the climb up an ancient delta feature in the crater where it landed. Dr. Briony Horgan, of Purdue EAPS, is cited in this article by BBC.

Purdue alum's TV show features Rube Goldberg machines
Zach Umperovitch, a 2011 Purdue alumnus, recently debuted "Crazy Contraptions," a competition show that focuses on the fun and intricate engineering involved in Rube Goldberg machines. He received his Purdue bachelor's degree in geology and geophysics in 2011 and his master's degree in 2014.

Hot Springs Suggest How the Tibetan Plateau Became the Roof of the World
The Tibetan Plateau has long represented both an opportunity and a conundrum for geophysicists. This vast tableland is the product of a long, slow collision between the Indian and Eurasian continental plates—a collision that began about 50 million years ago and is still going on today. As the only active continental collision site in the world, the plateau provides a unique opportunity to understand what happens when continents meet. But the long time frame and the great depths over which the collision has been occurring have left scientists puzzling over how exactly the plates are coming together. Dr. Marissa Tremblay, of Purdue EAPS, is cited in this article by EOS.

In its visit to Psyche, NASA hopes to glimpse the center of the Earth
NASA’s mission to the solar system's largest metallic asteroid promises to show us the iron-nickel core of a dead planet. New research, however, hints that this asteroid is much more. Dr. Brandon Johnson of Purdue EAPS is cited in this article by Popular Science.

Scientists come up with fresh take on moon mystery
The far side of the moon, which we can never see from our vantage point on Earth, looks surprisingly different than the orb we're used to seeing in the night sky. The near side we are so familiar with appears darker in places -- the result of the vast ancient lava flows, called lunar mare -- while the far side is covered in pock marks and craters but no mare. Why the two sides of the moon are so different has long puzzled space scientists. However, a study published last week in the journal Science Advances has come up with a new explanation for this lunar mystery. CNN reports on this study which includes a publication including Purdue EAPS Professor, Dr. Brandon Johnson.
