A new image from the ESA’s Mars Express Orbiter shows exactly how different regions in Mars are from one another. From the cloudy northern polar region all the way to the Helles Planitia down in the south, Mars is a puzzle of different terrain types. At the heart of it all is what’s known as the Martian dichotomy.

Humans to Mars. That’s the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. It’s a huge step to go from low Earth orbit, then lunar landings, and then all the way to Mars, a journey of hundreds of millions of kilometers and 2 years at the least.

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.

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.

Mars 2020 Rover Gets its Helicopter Sidekick
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.

Next year, the European Space Agency (ESA) will be sending the ExoMars 2020 mission to the Red Planet. This mission consists of an ESA-built rover (Rosalind Franklin) and a Russian-led surface science platform (Kazachok) that will study the Martian environment in order to characterize its surface, atmosphere, and determine whether or not life could have once existed on the planet.
In preparation for this mission, engineers are putting the rover and lander through their paces. This includes the ongoing development of the mission’s parachute system, which is currently in troubleshooting after a failed deployment test earlier this month. These efforts are taking place at the Swedish Space Corporation testing site in Esrange, and involve the largest parachute ever used by a mission to Mars.

The idea of somehow terra-forming Mars to make it more habitable is a visionary, sci-fi dream. But though global terra-forming of Mars is out of reach, the idea persists. But now, a material called silica aerogel might make make the whole idea of terra-forming Mars slightly less impossible.

It’s all about the detail.
In a way, Mars looks like a dusty, dead, dry, boring planet. But science says otherwise. Science says that Mars used to be wet and warm, with an atmosphere. And science says that it was wet and warm for billions of years, easily long enough for life to appear and develop.
But we still don’t know for sure if any life did happen there.

NASA has pioneered the development of all kinds of robots and robotic systems. Beyond its0 orbiters and satellites, which have been exploring the planets and bodies of the Solar System for decades, there’s also the growing army of landers and rovers that have been exploring planetary surfaces. Aboard the ISS, they even have floating robots (like CIMON) and humanoid robot helpers – a la Robonaut and Robonaut 2.
Looking to the future, NASA hopes to build robots that can do even more. While the current generation of rovers can drive across the plains and craters of Mars, what if they could explore cliffs, polar ice caps and other hard-to-reach places? That is the purpose behind the Limbed Excursion Mechanical Utility Robot (LEMUR) that is currently being developed by engineers at NASA’s Jet Propulsion Laboratory.

It’s easy to take for granted the detailed, almost real-time knowledge of Mars that we have at our fingertips. After all, in the not-too-distant past, Mars was largely mysterious. All we had were ground-based images of the planet. Now? Now we have daily weather reports and images of dust storms.
