The official account of the UAE mission to explore Mars, “The Hope Probe” on the social networking site, “Twitter”, revealed that the probe, as it approaches the passage of two months after its launch, has traveled about a third of the total distance of its journey to Mars, which is 493.5 million km, while it is currently continuing its journey successfully. Where it remained in front of the probe 321.5 million km before reaching its destination by next February.
Finish the exams
The probe has completed the post-launch tests with complete success, and in order for the probe to travel 493.5 million kilometers to reach Mars, during its long journey, it needs equipment and a star tracking camera that will help draw a picture of the probe’s position to ensure that it follows the required path, as it will need to Determining its precise location in space permanently, in order to be able to direct its sensor towards the Earth, and for this it relies on sensors to track the stars using the patterns of stellar clusters, in what is very similar to the method used by the Bedouins and sailors in ancient times to infer their way, while these tracking devices help Visualize placement of the probe to ensure it follows the desired path.
The star-tracking camera captured the first image of the probe’s direction towards Mars, at a distance of one million kilometers from planet Earth, as part of the standard testing and review plans to ensure that the space navigation devices work and comply with the specifications set for them, while the probe carries 3 scientific devices, specifically designed to provide The required information on “the causes of the disappearance of the Martian atmosphere”, while providing “the first comprehensive picture of how the atmosphere and weather changes daily,” as well as “the discovery of the interactive relationship between the upper and lower layers of the Martian atmosphere.”
The devices include a digital camera to capture high-resolution, color digital images of the planet Mars and to measure ice and ozone in the lower atmosphere, and the “Infrared Spectrometer” device, which measures the temperature and distribution of dust, water vapor and ice clouds in the lower layer of the atmosphere, in addition to a device ” UV Spectrophotometer »to measure oxygen and carbon monoxide in the thermal layer and to measure hydrogen and oxygen in the stratosphere.
The Hope probe will carry out its mission related to studying the Martian atmosphere from a scientific orbit that will be at the closest point to the surface of Mars at an altitude of 20 thousand kilometers and at the farthest point at an altitude of 43 thousand kilometers, and the probe will be able to complete a full circle around the planet every 55 hours with an orbital mile It is 25 degrees.
This orbit gives the Hope Probe an advantage over any other spacecraft, as none of the previous missions to Mars had a similar orbit, as they had orbits that only allow them to study the Martian atmosphere at one time during the day.
