The UAE is poised to make historical past with its makes an attempt to place the Emirati lunar rover, referred to as Rashid, on the moon.

On December 11, 2022, the UAE’s Rashid Rover, the world’s first Arab-built lunar rover, took off from Cape Canaveral Area Power Station in Florida.

The Rashid Rover flew into house atop a SpaceX Falcon 9 rocket housed inside a lunar lander designed by Japanese firm ispace.

It marked the start of an epic 385,000km odyssey that can make the UAE the fourth nation after the Soviet Union, the USA and China to land on the Moon if profitable.

Here is what you’ll want to know earlier than tonight’s date:

How can I see the stay occasion?

Area fans can tune in to Khaleej Instances stay streaming protection of the touchdown occasion throughout all digital platforms at 8pm tonight.

What’s the Rashid Rovers touchdown web site and why?

The Rashid Rover touchdown web site, which might be Atlas Crater, situated at 47.5N, 44.4E, on the southeastern outer rim of the Mare Frigoris (Sea of ​​Chilly), chosen to take care of flexibility throughout operations. Mare Frigoris is situated within the lunar far north and is a big lunar mare, or volcanic plain that fashioned between 3.9 and three.2 billion years in the past in the course of the Imbrian interval of lunar historical past, when volcanic exercise was at its peak.

The first touchdown web site has been chosen together with a number of contingencies, which will be utilized relying on the variables that happen in the course of the transit. The location meets the technical specs of the lander’s know-how demonstration mission and science exploration targets for the ELM mission.

It was additionally the positioning of a number of profitable lunar missions, together with the Apollo 15 and 17 missions, which collected samples from close by mountain ranges.

At what level does the descent start?

At roughly 19:40 tonight, the lander carrying Rashid Rover will carry out a number of orbital management maneuvers to achieve a 100 km round orbit across the Moon earlier than commencing the touchdown sequence. At this level, it should alter its pace and altitude to make a smooth touchdown about an hour later.

What maneuvers are carried out in the course of the touchdown sequence?

Throughout the sequence, the lander will carry out a brake, activating its important propulsion system to decelerate from orbit. Utilizing a collection of pre-set instructions, the lander will alter its angle and cut back pace to make a smooth touchdown on the confirmed lunar floor. The method will take about an hour.

How lengthy did the ELM staff talk with the rover?

The ELM staff will full practically a complete of 370 minutes of communication with the world’s most compact rover weighing simply 10 kg, earlier than touchdown, together with 12 mission checks for floor operations. Mission rehearsals are essential for the engineering staff to be ready and prepared with their schedules for execution after the lunar touchdown, and likewise to permit the completely different subsystem groups to synchronize their operational work.

What if the Rashid Rover is unable to land right this moment?

Ought to circumstances change, there are three different disembarkation websites and relying on the positioning, the disembarkation date might change. Various touchdown dates, relying on operational standing. The opposite dates are April 26, Could 1 and Could 3, 2023.

What are the challenges for the lunar rover?

Area consultants clarify that the moon’s gravity is about one-sixth of Earth’s gravity, which makes touchdown and controlling spacecraft actions tough. The moon’s lack of ambiance makes it tough to sluggish the spacecraft throughout its descent. The floor of the moon is roofed in a layer of positive mud referred to as regolith, which might attain a number of meters deep in some areas. This mud will be tough to navigate and may pose a threat to the spacecraft’s engines and touchdown gear.

There’s additionally the problem of speaking with the spacecraft in the course of the touchdown course of. The sign takes about 1.28 seconds to journey from the moon to Earth, which suggests there’s a communication delay. This delay could make it tough to make real-time modifications to the spacecraft’s trajectory in the course of the touchdown course of. Subsequently, it’s a advanced and tough process that requires cautious planning, exact engineering and expert execution.

What’s the success fee of the lunar mission?

Solely half of lunar missions involving touchdown on the lunar floor have been profitable up to now six many years, in keeping with NASA. The lunar touchdown is a really difficult process as a result of a number of causes together with gravity, lack of ambiance, regolith and communication with solely a 50% likelihood that the Rashid rover will efficiently contact base with the Moon.

What are the failed lunar missions within the latest previous?

Chandrayaan-2, mission to India in July 2019 – The mission lander, Vikram, suffered a tough touchdown on the lunar floor and was unable to speak with the bottom. The orbiter, nonetheless, remains to be working and conducting science observations.

Beresheet, Israeli mission in April 2019 – The spacecraft crashed on the lunar floor throughout its touchdown try as a result of a glitch in its important engine.

Chang’e-5 T1, China mission in October 2014 – The mission was a take a look at flight for China’s Chang’e-5 lunar pattern return mission, however the spacecraft was apparently unable to return to Earth at as a result of a malfunction in its propulsion system.

It’s value noting that whereas these missions haven’t been utterly profitable, they’ve nonetheless contributed beneficial information and data to understanding the Moon and its surroundings.

What’s the scientific mission of the lunar rover?

If issues go in keeping with script, after the Nominal Floor Operations part, which is the mission itself, for 10 to 12 days, the Rashid rover will conduct continued floor analysis and picture acquisition. The Rashid Rover will discover lunar soil traits, petrography and geology of the Moon, mud motion, floor plasma circumstances and the Moon’s photoelectronic sheath.
