The earth station receives the first live broadcast of the Hope Probe – across the Emirates – the Hope Probe


The Emirates Space Agency and the Mohammed Bin Rashid Space Center announced the reception of the ground control station in Al Khawaneej, Dubai for the first call from the Hope probe, where the first broadcast signal from the probe was recorded at 03:10 am Emirates time, after more than an hour after the launch of the probe, Let the UAE’s historic mission to explore the Red Planet begin, as the first Arab space mission to launch a new era of scientific achievements.

Details regarding the mission and next steps will be announced during a press conference that will be held today, Monday, at exactly one o’clock in the afternoon.

The Hope probe successfully launched to Mars from the Tanegashima Space Center in Japan at 01:58 a.m. today, when the probe separated from the launch rocket after less than an hour, specifically at 02:55 a.m., to do so automatically and launch the solar panels in At 03:00 am, before the panels are aimed with the probe towards the sun.

The Emirates Space Agency and the Mohammed Bin Rashid Space Center announced that the first broadcast signal from the Hope Probe was recorded at 03:10 am Emirates time after the probe operated its broadcast device, and then the Al Khawaneej Control Center began receiving the first data that the probe sent About an hour after launch, the center is currently analyzing this data to verify the probe’s condition and the position of the solar panels, and whether it has opened properly, as well as verifying that the probe is correctly aimed toward the sun.

The Al Khawaneej Control Center team also monitors the operations, data and coordinates of the probe’s status, ensuring that the main probe operation system is sound, as well as verifying the integrity of subsystems and scientific devices.

The separation of the probe from the launch missile constitutes an important step and a great incentive for the team to do more during the next stage, as the probe’s mission to explore Mars translates the state slogan the probe carries on its historic space flight “nothing impossible.”

The last stage witnessed many difficulties and challenges, especially those that accompanied the spread of the new Corona virus, which prompted the project team to work 24 hours a day to ensure the completion of all technical details of the project, and the transfer of the probe to the space launch station in Japan in the shadow of a halt The movement of transport and navigation worldwide.

Preparation and launch stages
Since arriving at the Tanegashima Space Center in Japan in April after a 83-hour trip, by land, sea and air, the Hope Probe has undergone high-precision testing and processing processes for launch, including filling the fuel tank for the first time with about 800 kg of hydrogen fuel and checking the fuel tank and making sure that there are no Any leaks, as well as testing communication and control devices, moving the probe to the launch pad, installing the probe on the rocket that will carry it into space, and charging the probe batteries for the last time. Final tests also included examination of the power system, communication system, navigation system, control system, propulsion and driving system, thermal system and software systems.

The launch of the Hope Probe was preceded by three basic processing stages; The first stage of removing the exploration camera cover consisted of before installing the missile on the launch pad, and the second stage involved moving the missile carrying the probe to the launch platform, which is a complex and delicate process, which took about half an hour, and necessitated the separation of the ground control equipment from the probe temporarily, so that the Activate this equipment when he reaches the platform.

The third stage of preparation was represented in the final preparations 18 hours before the launch of the probe, which included the withdrawal of nitrogen gas for maintaining the safety of the devices, and clean air in the combustion chamber of the missile, followed by an examination of the status of the batteries and the state of the probe, as well as ensuring the team’s readiness in the operating room before Three hours after launch, with the probe checking going on five minutes before launch.

The launch of the probe consists of three phases, where the first phase began technically with the countdown to launch the probe, through the separation of the probe from the missile that with the start of the probe to open its solar panels and make its first contact with the earth station in the Mohammed bin Rashid Space Center in Al-Khawaneej.

In the first stage of launch, the solid fuel impeller raises the missile after separating it from the launching platform, before this part automatically separates after completing its mission with the effect of gravity and the start of the rocket’s departure from the Earth’s orbit, and by separating this part the weight of the missile carrying the probe is reduced. To begin the period of zero gravity, the second part of the launch missile will separate.

And then begins the second stage of the launch process, until the probe of hope reaches its correct orbit around Mars, loaded on the third part of the launch rocket.

Flight of the probe
The journey of the probe of hope to Mars will take seven months, during which it will travel 493 million km, and it is expected that the orbit of the Red Planet will reach in February 2021, coinciding with the passage of fifty years since the establishment of the UAE federation.

The launch of the probe, Hope, was postponed twice due to unstable weather conditions in Japan, so that at dawn today, July 20, an ideal date will be chosen to move forward with the process, before closing the available window until August 3, 2020.

The separation of the probe from the missile is an important qualitative step in the efforts of a large team comprising more than 200 engineers and engineers from qualified Emirati cadres. During the last three months, the probe team representing the Emirates Space Agency and the Mohammed Bin Rashid Space Center distributed between the launch center in Japan and the Al Khawaneej ground control station in Dubai, where the team was able to complete all final tests and scientific follow-up related to the probe on time, with acceleration Work on the project in recent months, to overcome the technical and logistical challenges posed by the emerging epidemic of the Corona virus (Covid 19). In the world.

The probe will remain in the orbit of Mars a Martian year, which is equivalent to 687 days, as it will undertake a scientific mission which is the first of its kind in the world, by providing the first comprehensive picture of the climatic conditions on Mars throughout the year, along with researching the causes of fading of the upper layer of the cover Mars’s atmosphere, investigating the relationship between the lower and upper atmosphere layers on Mars, observing atmospheric phenomena on the surface of Mars, including monitoring dust storms, temperature changes, revealing the underlying causes of the erosion of the Martian surface, and searching for any relationships between current weather and conditions The weather is ancient for the Red Planet.

The scientific data collected by the Hope Probe will be deposited in a center of scientific data in the Emirates where the UAE scientific team will index and analyze this data, and share it for free with the worlds and specialized researchers in different parts of the world.
