If the Curiosity rover was paranoid, would it feel like it was being watched? Well, it is being watched, by its brother in orbit, the Mars Reconnaissance Orbiter. The MRO watched Curiosity as it travelled through the ‘Clay-Bearing Unit‘ in Gale Crater, during June and July, 2019.Continue reading “There’s the Curiosity Rover, On the Move, Seen from Space”
NASA and the DLR are making some progress with the Mole. The Mole has been stuck for months now, and NASA/DLR have been working to get it unstuck. After removing the mole’s housing to get a better look at it with InSight’s cameras, the team came up with a plan.Continue reading “It Looks Like it’s Working! NASA InSight’s Mole is Making Progress Again Thanks to the Arm Scoop Hack”
From some viewpoints, Mars is kind of like a skeleton of Earth. We can see that it had volcanoes, oceans, and rivers, but the volcanoes no longer fume and the water is all gone. A new image from the ESA’s Mars Express drives the point home.Continue reading “This Dried Up Riverbed Shows that Water Once Flowed on the Surface of Mars”
What happened to Mars? If Mars and Earth were once similar, as scientists think, what happened to all the water? Did there used to be enough to support life?
Thanks to the Mars Science Laboratory (MSL) Curiosity, we’re getting a better picture of ancient Mars and what it went through billions of years ago. A new study published in Nature Geoscience says that Mars likely underwent alternating periods of wet and dry, before becoming the frigid, dry desert it is now. Or at least, Gale Crater did.Continue reading “Curiosity Finds A Region of Ancient Dried Mud. It Could Have Been an Oasis Billions of Year Ago”
The mole is still stuck.
The mole is the name given to the Heat Flow and Physical Properties Package (HP3) instrument on NASA’s Mars InSight lander. It’s job is to penetrate into the Martian surface to a depth of 5 meters (16 ft) to measure how heat flows from the planet’s interior to the surface. It’s part of InSight’s mission to understand the interior structure of Mars, and how it formed.
But it’s stuck at about 35 centimers (14 inches.) The mole can do science shy of its maximum depth of 5 meters, but not this shallow. And NASA, and the DLR (German Aerospace Center) who provided the mole, have a new plan to fix it.Continue reading “Here’s NASA’s New Plan to Get InSight’s Temperature Probe Into Mars”
The SEIS (Seismic Experiment for Interior Structure) instrument on NASA’s InSight lander has sensed 21 Marsquakes since it was deployed on December 19th, 2018. It actually sensed over 100 events to date, but only 21 of them have been identified as Marsquakes. SEIS is extremely sensitive so mission scientists expected these results.Continue reading “InSight Has Already Detected 21 Marsquakes”
The title of Earth’s Earliest Life has been returned to the fossils in the Pilbara region of Australia. The Pilbara fossils had held that title since the 1980s, until researchers studying ancient rocks in Greenland found evidence of ancient life there. But subsequent research questioned the biological nature of the Greenland evidence, which put the whole issue into question again.
Now a new study of the Pilbara fossils has identified the presence of preserved organic matter in those fossils, and handed the ‘Ancient Life’ crown back to them.Continue reading “Confirmed. Fossils That Formed 3.5 billion Years Ago, Really are Fossils. The Oldest Evidence of Life Found So Far”
Springtime on Earth can be a riotous affair, as plants come back to life and creatures large and small get ready to mate. Nothing like that happens on Mars, of course. But even on a cold world like Mars, springtime brings changes, though you have to look a little more closely to see them.
Lucky for us, there are spacecraft orbiting Mars with high-resolution cameras, and we can track the onset of Martian springtime through images.Continue reading “Nothing Says Springtime on Mars Like Explosions of Sand”
Mars is well-known for being a dry and arid place, where dusty red sand dunes are prevalent and water exists almost entirely in the form of ice and permafrost. An upside to this, however, is the fact that these conditions are the reason why Mars’ many surface features are so well preserved. And as missions like the Mars Reconnaissance Orbiter (MRO) have shown, this allows for some pretty interesting finds.
Consider the picture recently taken by Curiosity’s
Work on the Mars 2020 Rover is heating up as the July/August 2020 launch date approaches. Mission engineers just attached the Mars Helicopter to the belly of the rover, where it will make the journey to Mars. Both the solar-powered helicopter and the Mars Helicopter Delivery System are now attached to the rover.
NASA’s Mars Helicopter will be the first aircraft to fly on another planet. The small rotor-craft only weighs 1.8 kg (4 lbs.) and is made of lightweight materials like carbon fiber and aluminum. It’s largely a technology demonstration mission, and is important to NASA. The overall mission for the Mars 2020 rover won’t depend on the helicopter, but NASA hopes to learn a lot about how to proceed with aircraft on future missions by putting the Mars helicopter through its paces on Mars.Continue reading “Mars 2020 Rover Gets its Helicopter Sidekick”
