NASA’s heading for the Moon again, but they’re not looking to cutting edge technologies to do it. On the contrary, they’re taking a step back and re-examining the methods they used to get there the first time, sending their young engineers to get a hands-on look at the old Apollo landers. They also plan to use tried and tested components from the shuttle program, including the ever-controversial insulating foam. The times may have changed, but the fundamental engineering challenges of a moon landing haven’t – sometimes it’s best to stick with what you know already works.
