The market is based in the Small Landing Pad and Landing Field . It allows you to buy and sell Resources in order to make more money or acquire items you do not have.

Market prices fluctuate every 20 minutes or so.  Make sure you buy at a low price and sell at a high price.

When you buy/sell, your ship leaves for Earth and returns to orbit 7 days later (168 seconds).  In the meanwhile, the Landing Field cannot do another transaction.  You need multiple Landing Fields to do concurrent market transactions.
