UNLV geoscientists count down to Mars rover landing

Perseverance, NASA’s most sophisticated rover to date, is expected to land on the surface of Mars on Thursday, February 18, around 3:55 p.m. ET.

After seven months through space, the Mars rover is scheduled to land on the red planet on Thursday. Two UNLV geologists have played a critical role in that research.

LAS VEGAS (FOX5) — In July, NASA’s Perseverance rover launched for Mars. It has been cruising space for seven months and is scheduled to touch down on the Red Planet on Thursday.

But before all that happens, Perseverance must pass the infamous seven minutes of terror: landing on Mars without help from NASA teams on Earth.

UF assistant professor on NASA’s Perseverance rover team talks Mars landing

When Amy Williams watched meteor showers with her parents as a kid, she knew it was only a matter of time before she would begin exploring the depths of space herself.’

Now, Williams’ galactic aspirations are directly contributing to one of the most ambitious missions to Mars.’

The proposal she wrote to join the mission was one of the 13 selected out of over 100 submissions, Williams said. When decisions were released in the fall, she initially refused to check to see if hers had been accepted for fear of rejection, despite previously serving on NASA’s Curiosity rover team.’

NASA Mars rover Perseverance reaches final arc of descent, set to face ‘seven minutes of terror’ before landing

NASA’s very own Mars rover Perseverance is set to complete its seven-month journey from Earth this week and land in the Jezero Crater on February 18, becoming the first artificial object to land on Mars since the Mars Insight Lander in 2018 and the first rover since 2012.

It is expected that the six-wheeled rover will take seven minutes to descend to the surface from the top of the Martian atmosphere. The final descent thus will occur during a white-knuckled interval known among engineers of the Jet Propulsion Laboratory (JPL) as ‘seven minutes of terror.’

It is known so because the final arc of the descent is the most critical and most dangerous part of the mission, where it may either land safely on the surface or end in a spectacular crash and explosion. ‘Success is never assured,’ said Al Chen, who is at the helm of the JPL descent and landing team. ‘And that’s especially true when we’re trying to land the biggest, heaviest and most complicated rover we’ve ever built to the most dangerous site we’ve ever attempted to land at. Perseverance has to do this all on her own. We can’t help it during this period,’ he added.

Teresa Martin: Let’s stop and appreciate what’s happening on Mars

This week welcomes another moment in the amazing: Sounds from Mars. Seriously. Later this week ‘ on Thursday if all goes according to plan ‘ the rover Perseverance will land on the red planet and, among its other scientific tasks, will also set up an audio feed.

OK, this won’t actually stream real-time audio, but it will record and share actual sounds from the Martian soundscape. Perseverance arrives on Mars with two microphones at the ready, set up to directly record in the Martian environment. NASA hopes that Perseverance will even record its own landing noises.

NASA’s Perseverance rover gears up to land on Mars in ‘seven minutes of terror’

After a seven-month journey, Perseverance will attempt to land on the Red Planet, sending the first signals back about 7:55am (AEDT) tomorrow.

To be successful, the SUV-sized spacecraft will need to complete a complex series of steps made famous by Curiosity, the last rover to land on Mars in 2012.

Going along for the ride is a miniature helicopter called Ingenuity ‘ NASA’s first attempt to fly a drone on another planet.

“This is by far the most ambitious set of missions to Mars in history,” deputy project scientist Ken Williford said.
