It was a pretty kick-ass week in terms of interplanetary exploration -- and not even just in NMS. Astronomers found a potentially habitable planet just 4.2 light years from us! This could be our first stop beyond Mars but it's going to take a while to get there, so we're going to have to travel light. That means bringing nothing but the most essential of supplies -- like scouter drones , custom-designed hazmat suits , efficient solar power generators and 8K televisions . Numbers, because how else are you going to calculate the interstellar rocket's payload fraction?
