I like this idea, except for the exploding. I think the graphic for a landing location is nice, rather than randomly landing on dirt or rock. A metal pad for landing on would be nice, it could be mine-able as well to move the beaming down location. Another thing to add with this, is allowing it to be placed underground, like if you build a bunker or put it inside of a house with walls. It works so long as the blocks behind it are human made, like brick or wooden walls. Or maybe even only working so long as it just has a glass window behind it as the wall. It can have a count down timer as well for allowing you to beam to your ship only if you remain on the pad for the full time, like 5 seconds. I think this is good, but it shouldn't take a very long time to mine, still double or triple the original beacon though. This beacon will need a button to toggle an overlay of it's zone of influence as well, the safe radius. It should allow working around non-aggressive monsters though. I think placing a second one might be nice too, allowing you to beam to your ship, then on your ship when you try to beam down, it asks you which one you want to beam to. This would allow you to name beacons too. This allows you to quick travel to the other side of the planet, especially good on super large worlds. Instead of half an hour of walking, you get 10 seconds to teleport to ship, 5 seconds to teleport down from ship, 15 second travel time. You shouldn't need to clear a massive area by the way for this to work, but a nice sized area sure. Maybe 10 to 15 blocks high, 7 to 15 blocks wide.
