Hope Mars Mission constellations in relation to the Sun. It will be equipped with two sets of rocket thrusters, which include four to six large delta V thrusters and eight to 12 small Reaction Control System (RCS) thrusters. The function of the delta V thrusters will be speed management, slowing down the probe or speeding it up as per requirements, while the RCS thrusters will be used for delicate manoeuvring. The reaction wheels within the probe will allow it to reorient itself while travelling through the space, helping it point its antenna towards Earth or point any scientific instrument towards Mars. To achieve
