The Hope Probe is successfully moving into its scientific orbit


We are thrilled to have you on our site. If you enjoy the post you have just found kindly Share it with friends.

The UAE Mars Exploration Project, “The Hope Probe”, announced today that the Hope probe has moved from the capture orbit to the scientific orbit, after the success of the first maneuver to operate the propulsion engines of the probe, which lasted for 8.56 minutes.

Thus, the probe is now in its final orbit around Mars in preparation for the start of its scientific mission, which will last for two years and may require a slight direction of its course later.

Imran Sharaf, director of the Emirates Mars Exploration Project, said: The transfer of the ‘Hope probe’ to the scientific orbit was very important, and I can say that it was the last decisive moment for the mission due to the possibility of its loss. The probe during the maneuver … we are currently evaluating the results of that operation, but we are confident that we will not need another major maneuver to adjust the orbit. “

The Hope probe moved from the capture orbit of 1063 km to 42,461 km to a scientific orbit from 20,000 km to 43,000 km, and this maneuver is the last dangerous operation to use propulsion engines during the journey of the Hope probe since it was launched into space on July 20, 2020.

The scientific stage of the probe will begin on April 14 with a number of calibration and testing processes aimed at ensuring the safety of the three scientific devices and ensuring the accuracy of their scientific measurements. The scientific mission of the probe, which will extend to a two-year period of collecting scientific data, begins on May 23, 2021.

In turn, Hessa Al Matrooshi, Deputy Project Manager for Scientific Affairs said: “Once we are able to reach our stable scientific orbit and start using our scientific tools, we will start building data sets and testing our systems through live data, and this data is that we will process, coordinate and participate in the scientific and academic communities. All over the world. Publicly through our site. “

The process of collecting scientific data about the red planet is a complex process that consists of making several “revolutions” around Mars and determining each group of measurements to build an integrated picture of the movement of dust, ice and water vapor in the layers of the Red Planet. Planet’s atmosphere. In addition, the probe will measure temperatures in the layers of the atmosphere and diffuse all hydrogen gas, oxygen, carbon monoxide and ozone.

Hope’s unique elliptical orbit, with a 25-degree angle, enables high-resolution data and images of the planet’s atmosphere to be collected every 225 hours / 9.5 days.

The Hope Probe carries 3 scientific devices: the Exploration Camera, which is a 12-megapixel digital camera that takes high-resolution images of Mars in addition to measuring water ice and ozone in the lower layer of the atmosphere through ultraviolet rays .. and an infrared spectrophotometer – combines the spectroscope Surface and atmospheric temperature information and measures the general distribution of dust, ice clouds, and water vapor in the lower atmosphere of Mars .. In addition to the UV spectrophotometer – it measures oxygen, carbon monoxide in the atmosphere, hydrogen and oxygen diversity in the planet’s upper atmosphere. the Red.

It is noteworthy that the engineers of the Mohammed bin Rashid Space Center worked on the design and construction of the Hope Probe and its scientific equipment in cooperation with international partners in knowledge, including the Laboratory of Atmospheric and Space Physics at the University of Colorado Boulder, Arizona State University and the University of California Berkeley.

The historic Al-Amal probe journey to the Red Planet coincides with the UAE’s golden jubilee celebrations.
