Andy Weir’s successful story “The Martian” forecasts that by 2035 NASA will have landed human beings on Mars 3 times, refined return-to-Earth flight systems and worked together with the China National Space Administration. We are now 10 years past the Hollywood adjustment’s 2015 release and 10 years shy of its imaginary timeline. At this midpoint, Mars expedition looks a bit various than how it was represented in “The Martian,” with both more discoveries and more debate.
As a planetary geologist who deals with NASA objectives to study Mars, I follow expedition science and policy carefully. In 2010, the U.S. National Space Policy set objectives for human objectives to Mars in the 2030s. In 2017, the White House Space Policy Directive 1 moved NASA’s focus towards returning initially to the Moon under what would end up being the Artemis program
principles for crewed objectives to Mars have actually gotten appeal, NASA’s real strategies for landing human beings on Mars stay delicate. Significantly, over the last 10 years, it has actually been robotic, instead of crewed, objectives that have actually moved discovery and the human creativity forward.
Robotic discoveries
Considering that 2015, satellites and rovers have actually improved researchers’ understanding of Mars. They have actually exposed numerous insights into how its environment has actually altered gradually.
As Earth’s next-door neighbor, environment shifts on Mars likewise show planetary system procedures impacting Earth at a time when life was very first taking hold. Therefore, Mars has actually ended up being a centerpiece for examining the olden concerns of “where do we come from?” and “are we alone?“
The Opportunity, Curiosity and Perseverance rovers have actually driven lots of miles studying layered rock developments that work as a record of Mars’ past. By studying sedimentary layers– rock developments stacked like layers of a cake– planetary geologists have actually pieced together a brilliant tale of ecological modification that overshadows what Earth is presently experiencing.
Mars was as soon as a world of appearing volcanoes, glaciers, lakes and streaming rivers– an environment not unlike early Earth. Its core cooled, its magnetic field failed and its environment wandered away. The world’s exposed surface area has actually maintained indications of those procedures since in the type of landscape patterns, series of layered sediment and mineral mixes.

One focus of clinical examination over the last 10 years is especially pertinent to the setting of “The Martian” Stops working to get reference in the story. To reach his finest possibility of survival, lead character Mark Watney, played by Matt Damon, need to cross a huge, dirty and crater-pocked area of Mars called Arabia Terra
In 2022 and 2023I, in addition to coworkers at Northern Arizona University and Johns Hopkins University, released comprehensive analyses of the layered products there utilizing images from the Mars Reconnaissance Orbiter and Mars Odyssey satellites.
By utilizing infrared images and determining the measurements of surface area functions, we connected numerous layered deposits to the very same episodes of development and discovered more about the prevalent collapsing nature of the surface seen there today. Due to the fact that water tends to seal rock securely together, that loose product suggests that around 3.5 billion years back, that location had a drying environment.
To make the conversations about this location simpler, we even dealt with the International Astronomical Union among others formerly unnamed craters that were pointed out in the story. One that Watney would have driven right by is now called Kozova Craterafter a town in Ukraine.

In spite of quick advances in Mars science, lots of unknowns stay. Researchers still aren’t sure of the exact ages, climatic conditions and possible signatures of life related to each of the various rock types observed on the surface area.
The Perseverance rover just recently drilled into and examined a special set of rocks hosting natural– that is, carbon-based– substances. Organic substances function as the foundation of life, however more in-depth analysis is needed to figure out whether these particular rocks when hosted microbial life.
The in-development Mars Sample Return objective intends to deal with these standard exceptional concerns by providing the first-ever unchanged pieces of another world to Earth. The Perseverance rover is currently caching rock and soil samplesconsisting of ones hosting natural substances, in sealed tubes. A future lander will then require to get and release the caches back to Earth
As soon as home, scientists can analyze these products with instruments orders of magnitude more delicate than anything that might be flown on a spacecraft. Researchers stand to find out much more about the habitability, geologic history and existence of any indications of life on Mars through the sample return project than by sending out human beings to the surface area.
This viewpoint is why NASA, the European Space Agency and others have actually invested some US$ 30 billion in robotic Mars expedition considering that the 1960s. The reward has actually been staggering: That work has actually set off fast technological advances in robotics, telecoms and products science. Mars objective innovation has actually led to much better stitches for heart surgical treatment and cars and trucks that can drive themselves
It has likewise strengthened the status of NASA and the U.S. as bastions of modern-day expedition and innovation; and it has inspired millions of trainees to take an interest in clinical fields.

Calling the red world home?
Colonizing Mars has a sexy appeal. It’s tough not to cheer for the indomitable human spirit while viewing Watney fight dust storms, oxygen lacks and food deficiency over 140 million miles from rescue.
Much of the momentum towards colonizing Mars is now connected to SpaceX and its CEO Elon Muskwhose specified objective to make mankind a “multi-planetary species” has actually ended up being a sort of rallying cry. While Mars colonization is romantic on paper, it is very hard to really bring out, and numerous critics have questioned the practicality of a Mars habitation as a sanctuary far from Earth.
Now, with NASA possibly dealing with an almost 50% decrease to its science budget plan, the U.S. dangers liquifying its planetary science and robotic operations portfolio entirely, consisting of sample return.
President Donald Trump and Musk have actually pressed for human area expedition to in some way continue to advance, in spite of those proposed cuts– successfully sidelining the robotic, science-driven programs that have actually underpinned all of Mars expedition to date.
It is these programs that have actually yielded mankind’s wealthiest insights into the red world and offered both researchers and writers like Andy Weir the structure to envision what it should be like to stand on Mars’ surface area at all.

Ari Koeppel is a planetary researcher and Earth Sciences Postdoctoral Scientist at Dartmouth College who studies surface area environments in the world and Mars utilizing information from satellites, rovers and drones. He has actually added to NASA objectives consisting of the Curiosity and Perseverance rovers, carried out fieldwork from Hawaii to Iceland, and just recently took a trip through the Arctic as a 2024 Explorer’s Club beneficiary to study defrosting permafrost. Enthusiastic about education and outreach, Koeppel has actually taught science courses, led wilderness trips and established trainee enrichment programs.
