The United Arab Emirates has postponed its Mars mission until Friday due to heavy rainfall at the launch site on Japan's Tanegashima Island. It was originally planned for Wednesday. The "Hope" probe will make a seven-month journey to Mars where it will study the atmosphere of the red planet and collect data for future human missions. The new launch is set for Friday and will make the UAE the first Arab nation to send a probe to Mars. What are the UAE's motivations?
