This is a real thing that actually happens. Let's say that you can land on Jupiter, but there is a chance that you will fall into the void. If you do manage to land, you are inflicted with blindness and you will find it very hard to take off again. So to get the diamonds, you have to send a hopper probe down to collect them. To send a hopper probe: 1. Fly to asteroids with a tier 3 rocket. 2. Right-click, which will display the cosmic catalog. 3. Select Jupiter. 4. Launch. 5. When the probe comes back, it will be full of diamonds! To craft a hopper probe, do one hopper and four shulker bullets. To collect shulker bullets, use them with a bottle.
