In the course of exploring Mars, the many landers, rovers and orbiters that have been sent there have captured some truly stunning images of the landscape. Between Spirit, Opportunity, Curiosity, the Mars Reconnaissance Orbiter (MRO) and others, we have treated to some high-definition images over the years of sandy dunes, craters and mountains – many of which call to mind places here on Earth.
However, if one were to describe the region where NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander will be landing (on Nov. 26th, 2018), the word “plain” would probably come to mind (and it would be appropriate). This region is known as Elysium Planitia, and it is where InSight will spend the next few years studying Mars’ interior structure and tectonic activity for the sake of learning more about its history.

The ESA’s Mars Express orbiter has spotted a funny cloud on Mars, right near the Arsia Mons Volcano. At first glance it looks like a plume coming out of the volcano. But it’s formation is not related to any internal activity in this long-dead volcano. It’s a cloud of water ice known as an orographic or lee cloud.
The cloud isn’t linked to any volcanic activity, but its formation is associated with the form and altitude of Arsia Mons. Arsia Mons is a dormant volcano, with scientists putting its last eruptive activity at 10 mya. This isn’t the first time this type of cloud has been seen hovering around Arsia Mons.

The possibility that life could exist on Mars has captured the imagination of researchers, scientists and writers for over a century. Ever since Giovanni Schiaparelli (and later, Percival Lowell) spotted what they believed were “Martian Canals” in the 19th century, humans have dreamed of one day sending emissaries to the Red Planet in the hopes of finding a civilization and meeting the native Martians.
While the Mariner and Viking programs of the 1960s and 70s shattered the notion of a Martian civilization, multiple lines of evidence have since emerged that indicate how life could have once existed on Mars. Thanks to a new study, which indicates that Mars may have enough oxygen gas locked away beneath its surface to support aerobic organisms, the theory that life could still exist there has been given another boost.

The idea of exploring and colonizing Mars has never been more alive than it is today. Within the next two decades, there are multiple plans to send crewed missions to the Red Planet, and even some highly ambitious plans to begin building a permanent settlement there. Despite the enthusiasm, there are many significant challenges that need to be addressed before any such endeavors can be attempted.
These challenges – which include the effects of low-gravity on the human body, radiation, and the psychological toll of being away from Earth – become all the more pronounced when dealing with permanent bases. To address this, civil engineer Marco Peroni offers a proposal for a modular Martian base (and a spacecraft to deliver it) that would allow for the colonization of Mars while protecting its inhabitants with artificial radiation shielding.

When it comes time to begin conducting regular crewed missions to Mars, and perhaps even establishing a permanent outpost there, astronauts and potential Martian settlers will have to know how to work with the local environment. Remember that scene in The Martian where astronaut Mark Whatney (Matt Damon) is forced to grow his own food in a plot of Martian soil? Well, it will be much like that, except with a lot more mouths to feed.
Naturally, knowing if this can be done requires a great deal of research and experimentation. To assist these efforts, a team of astrophysicists from the University of Central Florida (UCF) recently developed a scientifically based, standardized method for creating Martian and asteroid soil simulants. This imitation Martian dirt, which goes for $20 a kilogram (about $10 a pound), will help researchers determine what it takes to grow crops on the Red Planet.

In the coming decades, NASA has ambitious plans to send astronauts back to the Moon and conduct the first crewed mission to Mars. In order to accomplish these lofty goals, the agency is investing in cutting-edge technology and partnering with major aerospace companies to create the necessary spacecraft and mission components.
One such component, which will allow astronauts to travel to and from the lunar surface, is Lockheed Martin’s concept for a reusable lunar lander. The concept was presented today at the 69th annual International Astronautical Congress (IAC) in Bremen, Germany, where space agency and industry experts were treated to the latest in space exploration advancements.

A tiny electric motor on the Curiosity rover played a role in identifying a global Martian dust storm. The storm completely enveloped the planet between May and July, 2018. It was the biggest storm since 2007.

In the coming decades, NASA intends to mount some bold missions to space. In addition to some key operations to Low Earth Orbit (LEO), NASA intends to conduct the first crewed missions beyond Earth in over 40 years. These include sending astronauts back to the Moon and eventually mounting a crewed mission to Mars.
To this end, NASA recently submitted a plan to Congress that calls for human and robotic exploration missions to expand the frontiers of humanity’s knowledge of Earth, the Moon, Mars, and the Solar System. Known as the National Space Exploration Campaign, this roadmap outlines a sustainable plan for the future of space exploration.

A new image produced by the High-Resolution Imaging Science Experiment (HiRISE) aboard NASA’s Mars Reconnaissance Orbiter (MRO) has located the Opportunity rover on Mars. As expected, the rover was spotted on the slopes of the Perseverance Valley, where it went into hibernation mode about 100 days ago when the planet-covering dust storm darkened skies above the region.

There’s solid evidence for the existence of water on Mars, at least in frozen form at the planet’s poles. And a more recent study confirms the existence of liquid water at the south pole. But visitors to Mars will need to know the exact location of usable water deposits at other Martian locations. A ground-penetrating radar called ScanMars may be up to the task.
