Jim Green, NASA’s Retired Top Scientist, Says We Can Make Mars

Oh, that’s right, I’d love to see it sooner, but it’s not going to happen. There are some missions that are so big that they are called strategic missions. For them to actually happen, the stars must align. You have to propose it, have a specific situation, go to the NASA regulator and then present it to Congress. Every year, I propose a Europa mission. Each year. The authorities are not interested in going to Europa.

These beams over Europa are what made the Europa mission happen. I attended a meeting of the American Geophysical Union in 2013. Some scientists would talk about looking for a plume with Hubble on Europa, and I said, “Oh, my God.” I said this is great, I want to hold a press conference. I called NASA headquarters again, and they pulled it out. I took that information with me to headquarters and added it to Europa’s story. It’s really a corner. They said, “Well, maybe we should do this.”

Conference decided against put a lander on a mission. Would you like one?

I would love a lander, but it’s not in the cards. It makes the mission too complicated, but everything we do on Clipper transitions to a lander. I emphasize that we already have a high-resolution camera, while we are flying over certain areas, we will get the necessary information, “Let’s land there and be safe. ” Europa has some really dangerous terrain, so if we don’t get the high resolution images we’ll never be able to land.

You want to take a step, but not a big one. You fail when you do it. Viking is that example where we’ve taken a huge step forward. We don’t know where to go, we don’t know enough about the soil or the poison in the soil. Before, we didn’t really have a good idea of ​​where there was water on the planet. There are 10 things we should know before bringing two Vikings to the surface.

Do you still continue to work on scientific articles after retirement?

Oh, completely. I have a Mars paper to do. I have a Europa paper that I’m writing right now. I am working on a book on astrological biology. I have a great craving for science.
