And these could be ancient continents like the core continents of Earth or they could be something else, we don't know. Strange looking ridges, and mountains and valleys, some rising 10s of 1000s of feet. About eight or 9% of the surface of Venus are these mountain systems. And yet that rock scape surface, which has been visited, is an exciting place. The surface of Venus is like being 900 meters deep in the ocean, and it's hard to imagine that the gas near the surfaces is only 10 or 11 times less dense than liquid water but it's a gas. So, Venus is a strange planet because she has this ocean of air on top of herself, literally. I understand part of your expertise is looking at the geometric properties of the sedimentary systems on Venus, can you tell us more about this mysterious planet? And no one's been back since! And so, one of my dreams has been to working within NASA to bring the NASA team back to Venus in a way that will make her shine. I had worked on Venus in graduate school, and worked with missions that were led by both the United States and the Soviet Union back then in the 80s. And so, I was trained to do that in graduate school and as an undergraduate, and I came to NASA with the idea of being a catalyst for new science in new places and in new ways. And I came to NASA to do things like missions to places like Venus and Mars, to use the great tools and minds of the NASA workforce, the women and men that do all the engineering makes everything possible, but bring it into the science domain. It's the only place I've ever really worked. What is your background, and what is it that you do for NASA now? Which then allows us to see her so well at this time of the night sky. So, Venus’ big carbon dioxide atmosphere, and her gigantic cloud deck, make her just brilliant. Other planets in the solar system are dimmer like Mars, and even like our own Earth. And we can see her because she's very visible and bright. This ocean of air that reflects the light of the sun and lights it up like a shining balloon. If you use binoculars, you'll see this beautiful half lit Venus, which is a gorgeous thing to see in a very dark time of night. But on June 4th Venus will be at Zenith, as high as it gets in the night sky not the morning sky the night, and it will have the largest solar phase angle, it's over 50% of the disk of Venus will be visible. Venus does its dance around the sun and we see it wandering through the sky.
Jim Garvin, about this new exciting era of planetary exploration. WAMC Producer Jody Cowan spoke with NASA’s chief scientist and Principal Investigator for the planned 2029 DAVINCI mission to Venus, Dr. It’s a fascinating and strange world - similar in size and terrain to Earth - but also vastly different. This weekend is a great time to go outside and enjoy the views of our nearest planetary neighbor as Venus will be at its highest point in the night sky, giving us dazzling views of our sister planet. The future of Venus exploration is nearly upon us with NASA’s upcoming DAVINCI mission.
