EMIRATES MARS MISSION

EMIRATES MARS MISSION “HOPE PROBE”

The Emirates Mars Mission “Hope Probe” will be the first probe to provide a complete picture of the Martian atmosphere and its layers when it reaches the red planet’s orbit in 2021. It will help answer key questions about the global Martian atmosphere and the loss of hydrogen and oxygen gases into space over the span of one Martian year.

 

The Emirates Mars Mission (EMM) ​is the United Arab Emirates’ (UAE) ​first mission to Mars. EMM is designed to ​orbit Mars and study the dynamics in ​the Martian atmosphere on a global scale, and on both diurnal and seasonal timescales. Using three scientific instruments on board of the spacecraft, EMM will provide a set of measurements fundamental to an improved understanding of ​circulation and weather in the Martian lower and middle atmosphere. Combining such data with the monitoring of the upper layers of the atmosphere, EMM measurements will reveal the mechanisms behind the upward transport of energy and particles, and the subsequent escape of atmospheric particles from the gravity of Mars.

 

EMM will begin its journey to Mars from the Tanegashima island in Japan. The mission employs a 30-day launch period for the Hope Probe, opening on July 14 and ending on August 12, 2020. On the launch day, the Hope Probe will take-off on a Mitsubishi H-IIA rocket toward the east, on a trajectory that takes it over the Pacific Ocean.

As the rocket accelerates away from the Earth, the solid rocket boosters are expended, followed by jettisoning the fairing once it is no longer needed to protect the Hope Probe from the Earth’s atmosphere.

Once the first stage is completed, the rocket is jettisoned and put into the Earth’s orbit. It stays in the Earth’s orbit until the exact alignment with Mars is achieved after which it is reignited to push it on a trajectory towards Mars. With the right direction and velocity of 11km/s, the upper stage gently deploys the Hope Probe.
