Harry Coumnas is a renowned astronaut who performed intensive research to determine if Mars could ever be inhabited. As an astronaut, he assists the commander in controlling space shuttle flights, coordinates crew activities, and ensures safety. He also operates space exploration vehicles and is responsible for launching them into outer space. However, through his research, Coumnas determined that Mars has an inhospitable climate - it is too cold, has high carbon dioxide levels, low pressure, and bombardment from solar radiation without a magnetic field. These conditions mean that liquid water is not stable and life cannot exist on the surface of Mars.

2. Harry Coumnas Holds Distinct
Personalities as a Renowned Astronaut
 Harry Coumnas tends to be investigative, intellectual, introspective, and
inquisitive.
 Being the in charge of the vehicle and its crew on the mission, Harry assists
the commander in controlling the flight of the space shuttle.
 He coordinates crew activities and corrects system malfunctions.
 He also directs activities aboard the shuttle to ensure the safety of the flight
and success of the shuttle mission.
 He plans and trains for future space exploration at the NASA facilities and is
responsible for the vehicle and its crew on the shuttle mission.

3. Harry Mans Space Exploration Vehicles
and Launches into Outer Space
 Being the in charge of the crew, he is held responsible for the safety of the
crew and the mission’s success.
 He operates the vehicle with assistance from the pilot and is familiar with all
onboard systems.
 Harry assists the crew in deploying equipment into space and uses the remote
devices for retrieval of satellites and other objects.

4. He is Always Curious to Know If Mars
Can Ever Be Inhabited
 Harry Coumnas performed intensive research and came up with the fact that
Mars is on average inhospitably cold.
 The planet’s atmosphere is 95.3% carbon dioxide, and without a magnetic
field, its surface is bombarded by the Sun’s radiation.
 Moreover, the low atmospheric pressure combined with cold temperatures
means liquid water is not stable at the surface. Thus, in such conditions, life
cannot exist.
