Harry Coumnas Left the Confines of Spacecraft and Took Part in Extravehicular Activity as Mission Specialist
Harry Coumnas Teams Up With Astronaut Pilots to Form a Space Shuttle • Harry Coumnas coordinates operation within the spacecraft. • He serves in a role that requires the management of many everyday tasks. • He further schedules the activities of the crew, monitors the technological systems on the spacecraft, and manages inventory. • He believes that life in outer space is different and surviving the travel is quite strenuous with limited food supply and sleep.
Harry is Trained to Pilot in a Spacecraft, and Do Activities Related to Human Space Exploration • Harry believes that every trip into space can be a walk between success and disaster. • Previously working as mission specialist, he worked with pilots to conduct experiments, launch satellites, and maintain spacecrafts, and equipment. • He left the confines of the spacecraft and took part in extravehicular activity.
He 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 concludes that without direct evidence of past life, it is not possible to determine whether Mars was ever inhabited.
