Dubai: Final checks for the UAE’s Hope Probe mission to Mars are currently underway as it prepares for its launch from Japan’s Tanegashima Space Centre at 00:51.27 (UAE time) on July 15.
The checks are being led by a team of young Emiratis comprising of; Ahmed Al Yammahi, Mahmood Al Awadhi and Mohammed Al Aemri, who are responsible for mechanical operations including lift onto the rocket; Essa Al Mehairi, mandated with the responsibility of battery charging and spacecraft monitoring; Yousuf Al Shehhi entrusted with MLI (multi-layer insulation) closing; Omar Al Shehhi responsible for Aliveness Test and spacecraft monitoring; and Khalifa Al Mehairi who has responsibility of spacecraft monitoring.
Final checks
The Probe has undergone a series of tests since its arrival at the Tanegashima Centre in April. These tests, which are done over a period of 50 working days, entail functional tests of the spacecraft subsystems that include electrical power, communication, altitude control, command and control, propulsion, thermal control and software systems. The process also includes filling the fuel tank with about 800-kg of hydrogen fuel and ensuring that there are no leaks. It also requires moving the probe to the launch pad, installing the probe on the rocket, and ensuring the batteries are fully charged prior to liftoff.
After fueling, the Emirates Mars Mission (EMM) team will ensure that the Multi-Layer Insulation (MLI) and the Arming Plugs are properly sealed. This will be followed by joint operations with the Mitsubishi Heavy Industries (MHI) on powering the spacecraft for Aliveness Test, confirming the preparations as well as charging the spacecraft batteries and setting it for takeoff. This stage comprises three main tests, including Battery Charging, Aliveness Test, and Spacecraft Monitoring.
As part of its endeavour to ensure that the plans are on schedule, the core of H-IIA (H2A) launch vehicle was recently transported from the Nagoya Space Systems Toshibima Plant in the Aichi Prefecture to the launch station at Tanegashima Space Center in the Kagoshima Prefecture. The state-of-art Tanegashima Space Centre contributes to the exceptional successful launch by MHI, the strategic partner that is responsible for launching the Hope Probe.
Launch date
The Hope Probe is set to liftoff on July 15. The scheduled launch date represents the opening of the launch window for the mission, which extends to August 3 – in order to ensure that the probe reaches its desired orbit in the shortest possible time and the lowest possible energy. The liftoff process will comprise two stages. The first begins with the solid fuel impeller raising the rocket after separating from the launch platform – this part automatically separates after completing its mission. This leads to the second stage until the third stage – which lasts until the probe reaches its orbit around Mars. The MHI H2A launch vehicle weighs 289 tonnes and is 53-metres long.
The MHI H2A platform was chosen as a result of its proven expertise and reputation in space technology around the world, and its high success rates in launching spacecraft and satellites globally. The UAE, for its part, has previously collaborated with MHI to successfully launch the Khalifa Sat satellite. The Hope Probe is anticipated to enter the Mars orbit in February 2021, coinciding with the UAE’s Golden Jubilee celebrations to mark the historic union of the Emirates.
Impossible is possible
“The commencement of the final checks and tests on the Hope Probe in line with our schedule reiterates our commitment and detailed planning process to ensure the success of this mission. We are grateful to the wise leadership of the UAE for their unstinted support, and the relentless efforts and dedication of the team working on the project to complete this mission successfully,” said Dr. Ahmad bin Abdullah Humaid Belhoul Al Falasi, Minister of State for Higher Education and the Chairman of UAE Space Agency.
“Achieving success against all odds reflects the UAE’s strong legacy and identity that ‘Impossible is Possible’, which is embedded in the culture of the young men and women of this country,” he added.
Al Falasi reiterated that the Hope Probe is representative of the ambitions of the UAE and its positive message of hope to the region and the world. “The core message is to strive passionately and overcome obstacles to find solutions that benefit the humanity at large, which exemplifies the UAE leadership’s vision. We are confident of the Hope Probe reaching the Mars orbit in February 2021, coinciding with the UAE’s Golden Jubilee celebrations,” he said.
Suhail AlDhafri, Emirates Mars Mission Deputy Project Manager and Spacecraft Lead said: “The final checks are important steps to ensure that all systems are functioning and meeting the requirements before the fueling. Getting these parameters are vital prior to getting the Probe ready for the liftoff as per our launch window.”
The team
A team of Emiratis is leading the operation and supervising every aspect of the Probe’s preparation for its launch. The team includes Omran Sharaf Al Hashemi, Project Director of Emirates Mars Mission Hope Probe, Suhail Al Dhafari Al Muhairi, Deputy Project Manager of the Probe Development Team, Omar Al Shehhi, Launch Team Lead, Mohsen Al-Awadhi, Risk Manager, Youssef Al-Shehhi, Thermal Systems Engineer, Khalifa Al-Muhairi, Communication Systems Engineer, Issa Al-Muhairi, Power Systems Engineer, Ahmed Al-Yamahi, Mechanical Systems Engineer, Mahmoud Al-Awadhi Mechanical Systems Engineer, and Mohammed Al-Amri Ground Support Systems Engineer.
As a result of the COVID-19 pandemic, the team working on the Mission as divided into three sub-teams – considering the challenges on transportation, travel, logistics and adhering to the health procedures. While the first set of team members reached Japan on April 6 and underwent the mandatory quarantine and health checks, the second team arrived on April 21. The third team is still in the UAE, offering the necessary back-up support to the Mission. The transportation the Hope Probe from Dubai to the launch site on Tanegashima Island in Japan spanned more than 83 hours and underwent three major stages.
