Unscramble the Blue Letters


So I've posed a problem for you here, but I don't have a solution yet. We don't have a solution. But we're working on it. How are we working on it? Well, we've sent spacecraft to all three planets. Some of them are orbiting now, including the MAVEN spacecraft which is currently orbiting Mars, which I'm involved with and which is led here, out of the usivteniry of cloadoro. It's designed to measure atmospheric esapce. We have similar measurements from Venus and Earth. Once we have all our measurements, we can combine all these together, and we can understand how all three planets irtecnat with their space environment, with the surroundings. And we can decide whether magnetic fledis are iaprnotmt for habitability or not.

Some of them are orbiting now, including the MAVEN spacecraft which is currently orbiting Mars, which I'm involved with and which is led here, out of the University of Colorado. It's designed to measure atmospheric escape. We have similar measurements from Venus and Earth. Once we have all our measurements, we can combine all these together, and we can understand how all three planets interact with their space environment, with the surroundings. And we can decide whether magnetic fields are important for habitability or not.
