Good news/bad news on this week's episode of Looking Up. Now you can check the weather before your trip to Mars, but you probably won't like it. We are, or at least I hope we are, nearing the end of a long and cold winter. I for one do not like cold temps, but I do like what a great job the national weather service does in keeping us up to date on the weather forecast. Today I want to tell you about a very different weather prediction site that is available to you, over at nasa.gov.
