This weekend, three challenge officers will land on the Steel Warship: Officer Seifer, Officer Lenoa and Officer Margrethe. They will wait for you guys near the market, warehouse and spacecraft missions registrar respectively.

As long as you can get the right answers to their 10 questions within 5 minutes, you will be awarded lots of unit experience. But if your answer is wrong, you have to wait for 10 seconds to answer the questions again.
