Mars flyby and rendezvous with the flyby segment transferring the crew over. (see also Mars Excursion Module (MEM)) Alternately, a flyby-only human mission is also possible, without detaching at Mars, but to slingshot around Mars and back to Earth. In July 1965, Mariner 4 achieved a flyby of Mars with a return of data, providing the public and scientists with dramatically closer images of Mars. During the flyby Mariner 4 took 21 pictures amounting to about 1% of the surface of Mars. Mars was not globally mapped until the Mariner 9 orbiter, which over the course of 1972 to 1973 took thousands
Hope Mars Mission thrusters will be responsible for the delicate maneuvering. The expected travel time of the "Hope" probe is about 200 days at a speed of up to 40,000 km/h on its journey of 60 million kilometres. Upon arrival at Mars, it will study the atmosphere of Mars for two years. It is planned that its instruments will help build "holistic models" of the Martian atmosphere. The data is expected to provide additional data on the escape of the atmosphere to outer space. The "Hope" probe will carry three scientific instruments to study the Martian atmosphere, which include a digital camera for
