Mars exploration in focus as Europe prepares ExoMars Rover for search of life

2020 may be the year humankind takes its biggest step toward discovering evidence of life outside Earth. NASA and the European Space Agency (ESA) are working in its own rover which can roam Mars’s surface looking for life.

The ExoMars mission will be Europe’s Mars rover. Named after British DNA pioneer Rosalind Franklin, the golfing cart-sized robot is roughly one-third the size of NASA’s planned Mars 2020 rover and will look for signs that life may have existed on Mars.

The two rovers will behave as scientists that are distant, shining a wealth of data and graphics back to Earth.

Mars 2020 will collect Martian samples for return to Earth sometime in the future, whereas ExoMars will use its unique drill to burrow under the surface. The rover will find samples which were shielded from the radiation exits Mars’s surface. Researchers are hopeful that beneath the surface is really where we could find our proof of life. 

A Rover’s Purpose

Mars is a place. Because its air is a lot thinner than Earth’s, life as we understand it would have a tricky time surviving on the surface.

Billions of years ago, the surface of Mars was likely quite like that of Earth. But that changed when Mars lost its magnetic field, which subjected its surface to radiation, and stripped its air. All of that made survival above ground.

Historically, Mars assignments have hunted on the planet’s surface, typically at locations where there are signs of ancient water. This ’s because this is where people find life on Earth.

But since we haven’t found life in the world ’s surface however, mission scientists suggest we need to dig deeper. There could possibly be a few Martians underground.

The ExoMars rover (and corresponding lander) are a follow-on to ESA’s ExoMars Orbiter mission that reached Mars in 2016. That first mission consisted of 2 components: the Trace Gas Orbiter (TGO) and also the Schiaparelli landing demonstrator.

Landing on Mars

TGO caused it to Mars and is still performing great, nevertheless, Schiaparelli didn’t fare so well — that the lander crashed during its descent to the Martian surface. 

Landing a probe on Mars is not straightforward. To navigate the tenuous Martian setting requires a mixture of sophisticated landing equipment, such as even, retrorockets, and heat shields giant, inflatable airbags. 

Regardless of the crash landing, Schiaparelli attained its goal for a technology demonstrator. It also showed that the group needed to revamp the landing system before the rover starts. But, with less than a year until liftoff, the rover group is fighting with a proven piece of landing architecture: parachutes. 

So as to slow down the rover down, the mission demands multiple parachutes — one 15 meters (49 ft ) in diameter and one 35 meters (115 feet).  

As the rover starts its descent, atmospheric drag will slow down the craft from around 21 000 km/h (13,048 mph) to 1700 km/h (1,056 mph). This ’so when the first parachute will deploy. About 20 seconds later, at approximately 400 km/h (248 mph), the second chute will deploy. Last, the braking engines will kick about 1 km (or half a mile) above the ground, enabling the rover land safely on the Martian surface.

The entire sequence takes just half an hour.

Parachute Troubles

During high-altitude testing before this year performed, the craft ’ s parachutes torn as soon as they deployed. ESA engineers created several alterations, such as strengthening the parachutes and their storage bags with Teflon to create them simpler. The chutes are still tearing.  

The agency is currently turning to NASA to get support. ESA engineers are teaming up with the people at the Jet Propulsion Laboratory, to put the parachutes that are enhanced through months of rigorous testing. 

Meanwhile, the rover team is currently placing its hardware by means of a round of thermal testing. For 18 days it’ll be subjected to the exact temperature conditions experienced on Mars. 

The parachutes are predicted to complete testing in April 2020; then they are then going to be incorporated with the rover and shipped to the launching site in Kazakhstan. If any part of the mission misses its deadline, the entire project may be sidelined until the upcoming Mars launch window in 2022.
