Successfully, The Hope Probe moves to the scientific orbit.

 


The Emirates Mars Mission "Hope Probe" announced Monday, March 29, 2021, the transition of the Hope Probe from capture orbit to scientific orbit, following the success of the first maneuver by operating the probe's 8.56-minute propulsion engines.

Thus, the Probe is now settling in its final orbit around Mars in preparation for the start of its two-year scientific mission, and may require only a slight direction of its subsequent course.

It was a very important maneuver to move the Hope Probe into the scientific orbit. It was the last critical moment of the mission, because there was a possibility that the probe would be lost during the maneuver.

The Hope Probe moved from a capture orbit of 1063 km to 42461 km to a scientific orbit of 20000 km to 43000 km. This maneuver is the last dangerous propulsion engine operation during the Hope probe's flight since its launch into space on July 20, 2020.

The scientific phase of the probe will begin on 14 April with a number of calibration and testing processes aimed at verifying the integrity of the three scientific instruments and ensuring the accuracy of their scientific measurements. The scientific mission of the probe, which will span two years of scientific data collection, will begin on May 23, 2021.

The process of collecting scientific data on the Red Planet is complex, consisting of conducting several "cycles" around Mars and identifying each set of measurements to build an integrated picture of the movement of dust, ice and water vapor in the layers of the planet's atmosphere. In addition, the Probe will measure temperatures in the layers of the atmosphere and the spread of hydrogen, oxygen, carbon monoxide and ozone.

The Hope Probe's unique oval orbit, at a 25-degree angle, allows the collection of high-resolution data and images of the planet's atmosphere every 225 hours/9.5 days.

The Hope Probe carries three scientific devices: The Exploration Camera, a 12 megapixel-precision digital camera that captures high-resolution images of Mars along with water ice and ozone in the lower layer of the atmosphere through UV packets, and the infrared spectroscopic scale collects information on surface and atmospheric temperatures and measures the general distribution of dust, ice clouds and water vapor in the lower layer of the atmosphere.
