InSight is Losing Power, it Probably Will be Shut Down in a Few Months

The InSight Mars lander will cease science operations sometime in the next few months due to a decreasing power supply, mission managers said at a news conference on May 17. Martian dust covering the solar panels has reduced the amount of power to roughly 500 watt-hours per Mars day or sol. When InSight landed in November of 2018, the solar panels produced around 5,000 watt-hours each sol.

“At the end of the calendar year, we do anticipate having to conclude all InSight operations,” said Kathya Zamora Garcia, InSight’s deputy project manager said at the briefing, “not because we want to turn it off but unfortunately we don’t have the energy to run it.”

Martian Dust is Starting to Darken Ingenuity’s Solar Panels

This image of NASA’s Ingenuity Mars Helicopter was taken by the Mastcam-Z instrument of the Perseverance rover on June 15, 2021, the 114th Martian day, or sol, of the mission. The location, "Airfield D" (the fourth airfield), is just east of the "Séítah" geologic unit. Credits: NASA/JPL-Caltech/ASU/MSSS.

Like every solar-panel-powered vehicle on Mars, maintaining electrical power always becomes an issue at some point in the mission. Last week, mission controllers at the Jet Propulsion Laboratory lost contact with the Ingenuity Mars Helicopter. While they were able to re-establish communications, which is done through the Perseverance rover, engineers know that keeping Ingenuity’s batteries charged is going to be increasingly difficult as the dark winter is on the way to Jezero Crater.

Amazing! Ingenuity Helicopter Flies to the Perseverance Backshell and Parachute to See Them Close Up

You may recall we reported earlier this month that the Perseverance rover finally spotted its parachute and backshell off in the distance. This is the hardware that safely brought the rover to Mars surface on February 18, 2021.

But now, the incredible Ingenuity helicopter has snapped better images of those items, while it was hovering in the Martian air during its 26^th flight.

And what a mess! The poor backshell crashed to the surface, splitting into pieces.

Explorers Could Build Bricks on Mars with Bacteria and Pee

The famous Russian rocket scientist Konstantin Tsiolkovsky once said, “Earth is the cradle of humanity, but one cannot remain in the cradle forever.” Tsiolkovsky is often hailed as one of the fathers of rocketry and cosmonautics and remembered for believing in the dominance of humanity throughout space, also known as anthropocosmism. His work in the late-19^th and early-20^th centuries helped shape space exploration several decades before humanity first walked on the Moon.

Here’s Something Rare: a Martian Crater That isn’t a Circle. What Happened?

Most impact craters are usually circular and fairly symmetric, but not all. This odd-shaped crater on Mars is obviously an impact crater, but it has a unique oblong shape. What happened?

Perseverance Begins the Next Phase of its Mission, Studying an Ancient River Bed on Mars

On February 18, 2021, NASA’s Perseverance (Percy) Rover successfully landed in the dried-up lakebed known as Jezero Crater on Mars, beaming back images and video of its descent and landing to millions of space fans living on the planet that built and launched this incredible robotic explorer. With this landing came enormous excitement for a new era of robotic exploration of the Red Planet as we slowly continue to unlock the secrets of Mars and its ancient past, to include (hopefully) finding evidence of past life.

Imagine standing on Mars, and seeing this with your own eyes.

Curiosity is Going to Find a new Route Around This Tricky Patch Called “Gator-Back Terrain”

Right now, the Curiosity rover continues to climb Mount Sharp (Aeolis Mons), the central peak within the Gale Crater on Mars. This massive pile of rock and sediment was created over the course of 2 billion years by liquid water that flowed into the crater, creating a layered structure that stands around 5.5 km (18,000 ft) tall. Many of these layers were deposited when the crater is thought to have been a lakebed, which makes it a prime location to search for evidence of past life (and maybe present) on Mars.

Climbing this feature is hard work and can cause severe wear on Curiosity’s metal wheels. The rover began climbing the southern edge of “Greenheugh Pediment,” a gentle slope topped by sandstone rubble that scientists want to learn more about. A few weeks ago, the rover suddenly encountered a huge patch of wind-sharpened rocks known as ventifacts (aka. “gator back” terrain). This forced the mission team to plot an alternate route so that Curiosity can continue to get more life out of its wheels.

Perseverance’s Software Lets it Move Swiftly Across the Surface of Mars

Mars rovers are not known for being particularly speedy. Spirit and Opportunity managed a max speed of a whopping 5 cm per second, while Curiosity clocked in at a max speed of .1 kph. Over their long mission times, even those speeds opened up many potential areas to explore. But Perseverance is leaving them in the dust as it makes its way up to a river delta where it will begin its next round of sample collection.

Marsquakes are Caused by Shifting Magma

Before the InSight Lander arrived on Mars, scientists could only estimate what the planet’s internal structure might be. Its size, mass, and moment of inertia were their main clues. Meteorites, orbiters, and in-situ sampling by rovers provided other clues.

But when InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) arrived on Mars in November 2018 and deployed its seismometer, better data started streaming in.
