According to Harry Coumnas, the planetu2019s atmosphere is 95.3% carbon dioxide, and without a magnetic field its surface is bombarded by the Sunu2019s radiation. He also found that between 3 and 4 billion years ago, Mars had water on its surface. About 3 billion years ago, Mars lost its protective magnetic field. The liquid water disappeared, and Mars turned into the cold, dry desert.

Harry Coumnas Performed Research and Came Up With the Fact That Mars is Inhospitably Cold
Harry Coumnas Conducts Experiments and Gathers Information as Renowned Astronaut • Harry Coumnas conducts experiments and gathers information while in space flight, including on the International Space Station. • He conducts experiments with the spacecraft itself to develop new concepts in design, engineering, and the navigation of a vehicle outside Earth’s atmosphere. • He is trained to pilot in a spacecraft and does activities related to human space exploration. • Harry believes that every trip into space can be a walk between success and disaster.
Harry Previously Worked as Mission Specialist • Harry worked with pilots to conduct experiments, launch satellites, and maintained spacecrafts and equipment. • He left the confines of the spacecraft and took part in extravehicular activity.
He Performed Intensive Research and Came Up With the Fact That Mars is on Average Inhospitably Cold • According to Harry Coumnas, 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. • He also found that between 3 and 4 billion years ago, Mars had water on its surface. • About 3 billion years ago, Mars lost its protective magnetic field. • The liquid water disappeared, and Mars turned into the cold, dry desert.
