Science has increased as soon as the investigation of rival Mars starts

The sky above Mars will witness some shocking aeronautical displays over the next few days when three rival space robot probes will hit the red planet after traveling three miles into space.

The United Arab Emirates probe Hope Orbiter will arrive on Tuesday on the first day, followed by China’s Tianwen-1 spacecraft the next day. Finally, American Rover Perseverance will make its dramatic descent on the surface of Mars on 18 February.

It is a notable armada that manifests a growing desire of many countries to develop their own space technology and explore the solar system. However, how successful he was in reaching his goal this week and what happened next remains to be seen. There is a rough place to visit Mars.


In dozens of Mars expeditions since 1960, nearly half have crashed or the planet completely missed, thanks to component failures, rocket engine crashes, or software errors.

“It can be a heart-breaking business,” said UK physicist Colin Wilson of Oxford University. “I have equipment on the last two Mars missions – the Beagle Lander of Britain and the Schiaparelli probe of Europe – and every time I was in the control room, under my seat, grabbing my seat. And crashed on both occasions.”

Mars is a difficult destination for many reasons. First, it is millions of miles away, Open University astronomer Susan Schweinzer reported. “It is not like going to the moon, which is only a million miles away. This is equivalent to a put in the game of golf. In contrast, Mars is incredibly distant. It is completely tee-shot and quite tricky in terms of golf. “

In addition, Mars has an atmosphere but not a coarse one. “This means there is enough wind to drive dusty winds and winds that push your lander off course and into danger,” Dawson said. “On the other hand, it doesn’t get so thick that you can use a parachute for the entire descent of a probe.”

In the past, American space engineers relied on airbags for fittings for their labor and bounced them into deadlock after being dropped from the parachute. However, NASA’s new generation of rovers for such maneuvers is too complex and heavy and will instead rely on a rocket platform, called a sky crane, to lower it to the Martian surface.

This technology was used once before in 2012 to unload the American Rover Curiosity. Now Perseverance, a very heavy rover, will suit up on a journey dubbed NASA’s “Seven Minutes of Terror”. This is the time the SUV-shaped rover, weighing more than a tonne, will take the planet’s upper atmosphere to reach the surface of Mars after reaching an altitude of more than 13,000mph.

Atmospheric friction will bring about the first reduction in speed. Then a huge parachute will be released automatically and this will cut the probe speed to a few hundred mph. The rocket engine of the sky crane would then fire and the probe would slow down until it rose about 20 meters above the surface of the red planet.

The crane will lower the rover on the cable until it touches the surface, the cable will cut and the sky crane will fly to make its own uncontrolled landing a strongly safe distance. Only then will the engineers of NASA be given a message to tell them the good news.

In contrast, UAE’s spacecraft Hope, the Arab world’s first interplanetary spacecraft, will have a relatively simple time this week. It is designed only to orbit Mars, which it will achieve by a 30-minute burn of its main engine.

If the barn is successful that will slow down and orbit the spacecraft sufficiently to occupy Mars’ gravitational field. It is hoped that then the next two years to study Mars will better understand that over billions of years, it has lost a thicker atmosphere, which was able to retain water vapor on its surface, but which has gradually developed into a cold And was transformed into a dry world.

China’s Tianwen-1 is also scheduled to enter the Martian class this week. It will study the planet for several months before releasing a lander that will carry a 250-kg robot rover to the planet. If it works, China will become the second country in the world to successfully land only one robot vehicle in the world, after the US.

“China has already landed the rovers safely on the moon, but it will be a major achievement and really shows what their space scientists can do today,” Schweinzer said.

Crucially, the three probes form part of a spearhead of missions that should change our knowledge of the planet in the coming years, returning samples of Martian rock and soil to Earth for study. The work will be initiated by Persistence, which is scheduled to pinpoint promising geological sites, extract soil samples, and leave them at selected locations. Future missions, which include Europe and the Americas, will then retrieve these samples and return them to Earth.

“When we do this, we will hopefully find answers to the simple question: There is, or was, life on Mars,” Schweinzer said.

“This is an important issue – if life evolved on Mars, it means life on Earth independently, life means twice, separately, evolved in the same solar system and likely to be common in the universe is.”
