After building the LEGO Ideas Saturn V rocket I was curious about more real space sets.
LEGO once had a set of the Curiosity Rover which isn’t available anymore and is insanely expensive when You want to buy it used.
But thanks to Christoph Zeller I discovered a MOC on rebrickable.com
Searching for parts
Searching my own Lego collection for necessary bricks was fun but a bit cumbersome.
Buying via Bricklink Stores
rebrickable lets you export the part list which you can import into bricklink and chose shops where the parts are available
