Perseverance has already made its mark on scientific history by taking the first audio recording ever on Mars. But the instrument with the microphone, known as the SuperCam, wasn’t done there. It has plenty of other science to do, and recently it started running through some more preliminary tests. One of those tests happened to involve blasting a rock with a laser – while taking an audio recording of it.Continue reading “Perseverance Begins its Science on Mars With a Laser zap”
In absence of (yet) being able to step foot on Mars, we have robotic vicarious experiences through our rovers including Perseverance which landed this past February 18th. In addition to photos we’ve collected from the surface over the decades, our ever-improving data connection to Mars made it possible to see video from Perseverance’s landing. That dramatic unfurl of the parachute and dust spray of the landing thrusters – astonishing! I’m not ashamed to admit I cried. Through Perseverance we’re also experiencing Mars exploration with another sense – SOUND! Sound from another planet!! Using Perseverance’s Entry, Descent, and Landing Microphone (EDL Mic) we recently recorded audio of Perseverance’s wheels rolling across the Martian regolith (broken rocks and dust or “soil”). The audio segment below is an edited portion of sound highlights from a longer 16 minute raw audio file.Continue reading “More Audio from Perseverance: the Crunch of its Wheels on the Martian Regolith”
Lightning is one of the most powerful forces in nature. Up to 1 billion volts of electricity can flow into a strike in less than a second. Such a large energy buildup can be created by even a relatively simple cause – two particles rubbing together. A team at the University of Oregon has now studied whether those simple interactions might cause lightning on a place it hasn’t been seen before – on Mars.Continue reading “Dust Particles in the Martian Atmosphere can Create Static Electricity, but not Enough to Endanger the Rovers”
Many consider the various rovers we’ve sent to Mars as the next best thing to sending a geologist to the Red Planet. Spirit, Opportunity and Curiosity have carried all the necessary equipment similar to what human geologists use on Earth, and are able to navigate the terrain, “see” the landscape with the various cameras, pick up rock and dust samples with scoops, and then analyze them with various onboard tools and equipment.
In addition to all those things, the new Mars 2020 Perseverance rover will add a “sense of hearing” to its robotic toolkit. The rover includes a pair of microphones to let us hear – for the first time – what Mars really sounds like.Continue reading “Thanks to Perseverance, We’re Finally Going to Hear What Mars Sounds Like”
In the next few years, Mars will be visited by three new rovers, the Perseverance, Tianwen-1, and Rosalind Franklin missions. Like their predecessors – Pathfinder and Sojourner, Spirit and Opportunity, and Curiosity – these robotic missions will explore the surface, searching for evidence of past and present life. But even after years of exploring, an important question remains: where is the best place to look?
To date, all attempts to find evidence of life on the surface have yielded nothing, owing to the fact that the Martian environment is extremely cold, desiccated, and irradiated. According to a new study by an international team of researchers led by Cornell University and the Centro de Astrobiología in Madrid, the Atacama desert in the mountains of Chile could hold the answer.Continue reading “The Driest Place on Earth Could Help Predict How Life Might be Surviving on Mars”
In July there’s another launch window to Mars. It looks like China is ready to take advantage of it, by launching their first rover to the planet. It’s called Tianwen-1, meaning “Heavenly Questions”, or “Questions to Heaven.” The complete mission consists of a lander, an orbiter, and a rover.Continue reading “China’s Mars Rover Launches in Late July”
We all know how exploration by rover works. The rover is directed to a location and told to take a sample. Then it subjects that sample to analysis and sends home the results. It’s been remarkably effective.
But it’s expensive and time-consuming to send all this data home. Will this way of doing things still work? Or can it be automated?Continue reading “Rovers Will be Starting to Make Their Own Decisions About Where to Search for Life”
Flying low over the surface of Mars. Don’t tell me you haven’t dreamed about it, especially with some of the ‘Mars flyover’ videos that have been produced over the years using data from the orbital missions. And if all goes well – global pandemic not withstanding — a helicopter will be on its way to the Red Planet in just a few months.Continue reading “Mars Helicopter gets a Name: Ingenuity”
NASA’s Mars 2020 Rover is heading to Mars soon to look for fossils. The ESA/Roscosmos ExoMars rover is heading to Mars in the same time-frame to carry out its own investigations into Martian habitability. To meet their mission objectives, the scientists working the missions will need to look at a lot of rocks and uncover and understand the clues those rocks hold.
To help those scientists prepare for the daunting task of analyzing and understanding Martian rocks from 160 million km (100 million miles) away, they’ve gone on a field trip to Australia to study stromatolites.Continue reading “Scientists Search for Ancient Fossils in Australia, Practicing the Techniques They’ll Use on Mars”
NASA’s next mission to the surface of Mars is called the 2020 rover (in case you didn’t know already.) It’s planned launch date is July 17th, 2020, and it should land at Jezero Crater on Mars on February 18th 2021. The rover is still under construction at the Jet Propulsion Lab in Pasadena, California.Continue reading “You Can Use a Live Webcam to Watch NASA Build the Mars 2020 Rover”
