Using data from the Mars Reconnaissance Orbiter (MRO), planetary scientists have created one of the most unique and detailed maps of Mars ever. But fair warning, the biggest version of this is a could overload your computer.
Global CTX Mosaic of Mars is the highest-resolution global image of the Red Planet ever created and it even allows you see Mars in 3D.
There’s a reason Jezero Crater was chosen as the landing site for the Perseverance Rover: it is considered one of the likeliest places to find any evidence if Mars was ever habitable for long periods of time. In this great new flyby video from ESA, you can get a birds-eye look at Perseverance’s home.
Created from data ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter, the video takes you on an aerial tour of the crater. From this perspective, you can see the water features in this ancient impact crater and understand why this was considered one of the best places to explore Mars.
Facial pareidolia is the human tendency or illusion of seeing facial structures in an everyday objects – such as seeing the “man in the Moon,” or the face of Jesus on a piece of toast. But here’s a newly found crater on Mars that might be a case of ‘bear-adoilia.’
For the first time, a spacecraft has detected acoustic and seismic waves from impacts on Mars. NASA’s InSight lander made the detections from four meteoroids that crashed on Mars in 2020 and 2021. Ever since the mission landed on the Red Planet in 2018, scientists have been hoping to be able to detect impacts with InSight’s seismometer, which was mainly designed to sense Marsquakes. But these impacts are the first the lander has detected.
This interesting image from the HiRISE camera on the Mars Reconnaissance Orbiter shows a field of fascinating dunes called barchan dunes. These dunes have formed along a cliff in Chasma Boreale, in the North Pole of Mars.
Because of the orbiters and landers that have studied Mars over the years, scientists have learned that water ice is very likely locked away just under the surface throughout the planet’s mid-latitudes. These regions – especially in the northern hemisphere — are mostly covered with smooth material and scientists suspect ice is just underneath.
But sometimes, images like this give one from the HiRISE (High Resolution Imaging Science Experiment) camera on the Mars Reconnaissance Orbiter, provides a glimpse of the ice that might be buried below the surface. This image shows a cliff jutting out of the normally smooth terrain, and the cliff is covered with bright ice.
Pit craters are found on solid bodies throughout our Solar System, including Earth, Venus, the Moon, and Mars. These craters – which are not formed by impacts — can be indications of underground lava tubes, which are created when the top of a stream of molten rock solidifies and the lava inside drains away, leaving a hollow tube of rock. If a portion of the roof of the tube is unsupported, parts of it may fall in, making a hole or a pit along the lava tube’s path.
When NASA sent the Mars Reconnaissance Orbiter (MRO) to the red planet in 2006, the spacecraft took an instrument with it called CRISM—Compact Reconnaissance Imaging Spectrometer for Mars. CRISM’s job is to produce maps of Mars’ surface mineralogy. It’s been an enormous success, but unfortunately, the loss of its last cryocooler in 2017 means the spectrometer can only undertake limited observations.
But CRISM is going out with a bang, creating one final image of the surface of Mars that NASA will release in batches over the next six months.
From orbit, this landscape on Mars looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren’t created by Martian bees or spiders; they are actually formed from a ongoing process of seasonal change from created from water ice and carbon dioxide.
Changes are always taking place on Mars, from factors like seasonal variations and wind. But there’s one other aspect that changes the surface of Mar quite often: impacts.
Here’s a new impact crater that was seen by the Mars Reconnaissance Orbiter. Exactly when the crater formed is not known, but this image was taken on July 24, 2020 and in a previous image of this site taken in 2018, the crater is not there.
