When planning space exploration, scientists face many
challenges. One issue is the weight of the items being
transported. They can use the engineering design process
to help minimize the weight of materials on board a
spacecraft.
The engineering design process starts with a statement of the problem to be
solved. Which sentence best states the problem described above?
O A. Metal is stronger than plastic, but it is also much heavier.
OB. Space vessels must carry heavy equipment but also minimize
weight.
O C. The longer a space flight will last, the more equipment must be
carried
D. Lower gravity on the Moon means that objects weigh less on the
Moon than on Earth.
