The NASA Mars rover Curiosity is still out there, day in and day out, doing Science for us all! The latest discovery to come from this hard working and vastly in-extra-innings ‘bot centers around the 3 mile tall Mount Sharp, located in Gale crater on the Martian surface. Using an improvised gravimeter, rigged from the existing accelerometers on board the vehicle, they have found strong evidence that the towering mountain was created through a long process of stacking wind blown material as it was driven into the crater. This is the far less likely result, geologically speaking, but thanks to the new ability to measure the surprisingly low density of the material comprising Mount Sharp, the stacking model looks more likely than one of erosion over time.

The best takeaway here, is of course that it’ll still make a great ski slope in a few years, but may need a little firming up in places. Also, that Curiosity is still working hard, along with the Earth-side engineers who continue to wring valuable Science from our future spare home planet, every hour of the day!

In a paper just published on January 4th, Alberto Fairén of Cornell University and the Center of Astrobiology in Madrid discusses the impact that human exploration of Mars is likely to have on that planet. The Anthropocene is a term used to describe the massive changes that have taken place to the Earth resulting from human interaction and activities, and for a similar effect to take place on Mars in a few decades would make it the first multiplanetary geological period.

The changes to be expected on Mars range from unavoidable microbial contamination of the environment to wholesale geographical changes necessitated by habitats and eventual pizza joints (per Musk) that will spring up over time.

One hopes that lessons we can take from the treatment of our own planet, which in many ways hastens the need to find a spare one, could help inform how we should treat our potential new home. How that plays out, and with what wisdom, we will know in the fullness of time, or at least our Grandchildren will.

A lot of Mars news has been coming out over the past few weeks, fellow red planet enthusiasts, and we are certainly behind in discussing it! Suffice to say, the successful touchdown of NASA’s InSight Lander on November 26th has opened up a new era of science on our brother world. Along with a ton of cool pictures, what really is exciting is the first even audio recording of the martin wind. Behold!

It’s sometimes difficult to wrap the mind around what it would really be like to leave the Earth and voyage to Mars. Well, back on May 5th the Gazette reported on the launch of the NASA Mars InSight Lander, and now that lander is several weeks away from landing on the red planet! The landing is projected to be on November 26th, with touchdown taking place at 11:47am Pacific Time, so set your watches.

The lander will utilize a supersonic parachute once it enters the martian atmosphere, and according NASA Chief Engineer Rob Manning, will decelerate from 12,300mph to 5mph at which point retro rockets will bring it to a soft landing on Elysium Planitia.

Remember that the intended mission of this lander is to study the interior of Mars, including gaining insight into Marsquakes. Through this research, additional knowledge about planetary formation and interiors will be gained, allowing us to better understand our very own homeworld.

For all of the additional information you can possibly want on the landing, be sure to check out the official Press Kit.

The culmination of excitement and tech know-how has finally appeared to produce the perfect storm to get us on our way to Mars in the next decade or so. This is great news, and brings with it so many exciting challenges. You thought getting Tang from the original NASA space program was a boon? Just imagine the technologies and techniques we will have to invent and refine in order for the first hearty souls to live off-world.

As such, research is being done on how we can produce food to keep those early settlers alive and fed. Hydroponics is of course a strong area of study, as well as how to coax food from the martian surface. Turns out that poisonous regolith is not the most advantageous or friendly material in which to try to grow potatoes. However, as humans often do, we are finding ways to make it work, or at least some possibilities. At the Florida Institute of Technology as well as Villanova (both excellent links – follow those), students are running experiments with core crops including lettuce, peas, peppers and hops (Mars Bars!) in a variety of soil types simulating martian conditions.

While it is widely accepted that some sort of treatment will need to be done to the martian soil before it is able to produce crops, or frankly not kill us outright, the methods to speed up that remediation and align the hostile environment with human-supporting conditions as quickly as possible seem to get a little better every day.
