In Case You Missed It: Farming on Mars

Back in a November 2020 article, Science News discussed the difficulties of farming on Mars, noting it was not as easy as Matt Damon’s character made it seem in the film The Martian. In fact, toxins discovered in the Martian soil has proven that growing potatoes with a bit of man-made manure is not possible.

In the article, “Farming on Mars will be a Lot Harder Than ‘The Martian’ Made it Seem,” the author noted that researchers put together a variety of soil samples to match the surface of Mars and determined that the soil that most closely matched the Martian soil was unable to grow vegetation for any length of time. Once that soil was modified to include calcium perchlorate, which makes up about 2 percent of Martian soil, nothing could grow at all. In other words, Matt Damon would have starved if he only had a latrine to support him.

The researchers are testing other possible soil types using materials that can be found on Mars, so Martian potatoes (or at least legumes) may be possible. We will just need to send Mr. Damon back to Mars to test these new approaches.

Extra: The BBC’s Science Focus website posted a more hopeful article around the same time highlighting what can be grown on Mars, but it also outlined a number of problems that will impact Martian farming, including less sunlight, lower temperatures, thinner atmosphere, radiation, and extreme seasonal variations. We don’t always realize how good we have it back here on our home planet.

A Day In Astronomy: The Launch of the Mars Odyssey

On this day in 2001, NASA’s Mars Odyssey orbiter was launched towards Mars to map and search the Red Planet for water. The mission itself took its name from Arthur C. Clarke’s novel 2001: A Space Odyssey.

The Mars Odyssey successfully discovered Martian water. Project Scientist Jeffrey Plaut of NASA’s Jet Propulsion Laboratory in Southern California, which leads the Odyssey mission, stated that “Before Odyssey, we didn’t know where this water was stored on the planet…We detected it for the first time from orbit and later confirmed it was there using the Phoenix lander.”

In addition to conducting its own studies, the Mars Odyssey was also used as a space satellite relaying data between Earth and Mars from other scientific missions, such as NASA’s Spirit and Opportunity rovers. The orbiter is part of what is called the Mars Relay Network, currently consisting of five orbiters (see below).

The Mars Odyssey is now the oldest oldest spacecraft still working at the Red Planet. It should be able to continue its work through 2025. You can find more information about the mission from this NASA site.

Here is what the Canadian Space Agency (CSA) tweeted about this image:

Wow! While travelling on the surface of Mars, the Perseverance rover found the place where all the missing socks from the dryer end up!

Okay, it is from this time last year, but it’s still funny. Happy April Fools’ Day!

Status of NASA’s Martian Mission

Now that we have learned a little more about China’s Martian rover, maybe we should check on NASA’s Perseverance Rover. According to a recent press release from NASA, earlier this month Perseverance started its three-mile trip to the river delta on the rim of Jezero Crater after already exploring the Martian surface for about 13 months. This delta may contain evidence of ancient microbial life. As with the Chinese rover mission, the collected samples will be returned to Earth via a later mission.

The Perseverance arrived on the Martian surface February 18, 2021. The mission has already shown success with the Ingenuity Helicopter, while the rover is showing greater abilities to self-navigate. All of this is proving to be promising for future robotic exploration of the planet.

Chinese Martian Rover Images

The China National Space Administration (CNSA) Watcher site posted the above before and after selfies taken by the Zhurong Mars Rover. The top shot was taken on May 19, 2021 and the bottom shot on January 22, 2022. You can see the dust that has accumulated in less than a year on the rover’s panels. The site notes that the rover has the ability to vibrate and loosen the accumulated dust.

China launched Tianwen-1, which carried the rover, on July 23, 2020. It went into orbit around Mars in February 2021, with the Zhurong Rover landing on the Martian surface on May 14, 2021. China sent the rover to the Red Planet to find evidence of water. If all goes well, China hopes to bring a Martian samples back to Earth in a subsequent mission. The Planetary Society has some helpful information here on the Chinese mission.
