Perseverance is having a proud parent moment in this image, looking like it’s waiting with a child at the bus stop on the first day of school.Continue reading “Perseverance Takes a Selfie With Ingenuity. It’s Almost Time to fly”
Did the Perseverance rover capture a rainbow on Mars? This image, from the rover’s left rear Hazard Camera, sure looks like it. But alas, no. However, film director JJ Abrams would be proud.Continue reading “Perseverance Captured This Image of a “Rainbow” on Mars, but it’s just a Lens Flare in the Rover’s Camera”

On April 3rd, the Mars Ingenuity helicopter was removed from its carbon-fiber shield on the Perseverance rover’s belly. On Sunday, April 11th, it will make its first attempt at a powered, controlled flight, becoming the first aircraft to operate on another planet. In the meantime, Ingenuity accomplished another major milestone as it survived its first full night on the Martian surface.Continue reading “Mars Helicopter Survives its First Night on Mars is Getting Ready to Fly”
Perseverance has been busy lately. After testing its systems out, taking the first sound recording ever on the Red Planet, and dropping off its helicopter sidekick, now it has the opportunity to work on its primary mission: stare at some rocks. And occasionally zap them with a laser.Continue reading “Here’s a Strange Rock That Perseverance Shot With its Laser”
Roughly 4 billion years ago, Mars looked a lot different than it does today. For starters, its atmosphere was thicker and warmer, and liquid water flowed across its surface. This included rivers, standing lakes, and even a deep ocean that covered much of the northern hemisphere. Evidence of this warm, watery past has been preserved all over the planet in the form of lakebeds, river valleys, and river deltas.
For some time, scientists have been trying to answer a simple question: where did all that water go? Did it escape into space after Mars lost its atmosphere, or retreat somewhere? According to new research from Caltech and the NASA Jet Propulsion Laboratory (JPL), between 30% and 90% of Mars’ water went underground. These findings contradict the widely-accepted theory that Mars lost its water to space over the course of eons.Continue reading “Maybe Mars Didn’t Lose its Water After All. It’s Still Trapped on the Planet”
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”
On March 4th, 2021, the Perseverance rover began driving from its landing site on Mars. During this drive, the rover covered 6.5 meters (21.3 feet) and conducted some basic maneuvers and instrument tests. In keeping with a NASA tradition where mission controllers give unofficial nicknames to various geological features, the team also consecrated the landing site by naming it after a famous science fiction author.
Henceforth, the site where Perseverance landed will be known as the “Octavia E. Butler Landing,” in honor of the groundbreaking science fiction author who passed away in 2006 (she was 59 years old). Butler is renowned for being the first African-American woman to win both the Hugo and Nebula Award and was the first science fiction author honored with a MacArthur Fellowship (in 1995).Continue reading “Perseverance’s Landing Site Named for Octavia Butler”
On February 18th, 2021, NASA’s Perseverance rover landed in the Jezero Crater on Mars. Over the next two years of its primary mission, this robotic mission will carry on in the search for past life on Mars, obtaining soil and rock drill samples that will be returned to Earth someday for analysis. And as of March 4th, the rover conducted its first drive, covering 6.5 meters (21.3 feet) across the Martian landscape.Continue reading “Perseverance has Started Driving on Mars”
A month on, we’re all still buzzing about the Perseverance rover’s perfect landing in Jezero Crater on Mars, back on February 18, 2021. Over the past few weeks, NASA has released more stunning imagery and footage of the landing, and since then the world-wide cadre of citizen scientists and image editing enthusiasts have been springing into action to enhance and augment all the incredible scenes captured by Perseverance’s collection of high-resolution cameras.Continue reading “Perseverance’s Landing Seen in Full Color, Thanks to Citizen Science”
