Question

NASA is currently working on sending humans to Mars by the 2030s. When astronauts arrive

on Mars, NASA intends to already have their food supply there. The food will be sent by an
unmanned spacecraft. It will then be stored, unrefrigerated, for five to seven years.
List at least two likely constraints and two likely criteria for this engineering design problem.

Answer 1

With regards to NASA's ambition to send humans to Mars, is an encouraging idea. Also, the aim of sending food supply by unmanned spacecraft before the 2030 project though noble is filled with constraints and design problems.

For the constraints,

1. The spacecraft could be lost on the space before it reaches its destination being Mars. This is because, lack of communication between the control unit on earth and the spacecraft signify it being lost forever.

2. The food supply is bound to spoil on Mars since it would be stored unrefrigerated. This is as a result of the actions of the micro organisms acting on them.

For the criteria for the engineering design problem:

1. The distance between earth and Mars is very far

2. Not factoring in the preservation method into the unmanned aircraft.
