The last seven days during which the final preparations for the countdown to launch the UAE’s Probe of Hope into its orbit on Mars will start on Tuesday (July 8, 2020) from Japan’s Tanegashima Space Centre at 00:51.27 (UAE time) on July 15.

The preparation will be conducted through three basic steps, including safety checks of the probe and its readiness to launch, preparedness of the ground station and the operations team, and the technical checks of the rocket that will carry the probe.

Hope Probe will provide a complete picture of the Martian atmosphere

  • Understand climate dynamics and the global weather map through characterising the lower atmosphere of Mars.
  • Explain how the weather changes the escape of hydrogen and oxygen through correlating the lower atmosphere conditions with the upper atmosphere.
  • Understand the structure and variability of hydrogen and oxygen in the upper atmosphere, as well as identifying why Mars is losing them into space.
  • To Improve the quality of life on Earth by pushing our limits to make new discoveries
  • To encourage global collaboration in Mars exploration and demonstrate leadership in space research.
  • To build Emirati capabilities in the field of interplanetary exploration.
  • To build scientific knowledge because a sustainable, future-proof economy is a knowledge-based economy.
  • To Inspire future Arab generations to pursue space science.
  • To establish the UAE’s position as a beacon of progress in the region.

These seven days are necessary before placing the probe on the front of the space rocket.

The probe was subjected since its arrival at the space centre in Japan, to a 6 high-precision processing operations prior to the launch. They began by filling the fuel tank for the time with about 700 kg of “hydrazine” fuel, and ended by charging the probe batteries for the last time.

The launch operation is considered the most important stage among all stages related to the "Probe of Hope". It requires precise coordination in advance among all teams. The day of the launch also relies on various factors that are observed with great accuracy. Among these is the weather condition, which is the most important for the launch. It should be followed up and monitored continuously through the launch window, which remains available for about a month, and occurs every two years, due to the approaching of Mars from Earth.


Since its arrival at the space centre on Tanegashima Island in Japan on April 25th, a team of young Emirati cadres has been overseeing all aspects of preparing the "Probe of Hope", to launch its historic mission.

Hope Probe consists of a compact, hexagonal-section spacecraft, built from aluminium in a stiff but lightweight honeycomb structure and surfaced with a strong composite face-sheet. It weighs approximately 1,500 kg and measures 2.37 metres wide and 2.9 metres tall. It includes a high-gain antenna with a 1.5 m wide dish for communication with the Control and Operations Room at the Mohammed Bin Rashid Space Centre.

It also includes a digital self-controlled camera that captures high-resolution colour images, a UV spectrometer to study the upper layers of the atmosphere of Mars and track the effects of hydrogen and oxygen gases in deep space, an infrared spectrometer to study the pattern of changes in temperature, ice, water vapour and dust and three 600-watt solar panels positioned on both sides of the Probe to remain closed during the launch process and open automatically when the Probe arrives on its track.
