Astrobiologist Answers Mars Questions
Space scientist and astrobiologist Erika DeBenedictis joins WIRED to answer the internet’s burning questions about The Red Planet. How long does the trip to Mars take with current technology? Why is it red? How realistic was the movie ‘The Martian?’ How long would it take to effectively terraform Mars to sustain human life? Does Mars…

This was great, but her full time job is selling Mars colonization. Thus her bizarre statement on terraforming Mars in our lifetimes.

For a scientist it’s very odd that you refer to temperature in fahrenheit.

I hate it so much when you have a very specialized expert you can ask so many possible question and most of them are just questions you could literally ask your highschool science teacher and get a correct answer.
Like bro I don’t need an Astrobiologist to explain to me why the mars rovers batteries last so long, I CAN SEE THE SOLAR PANELS ON THE PICTURES. I need her to explain stuff about her job that a regular astronomer can’t

” Occupying Mars ” … just ain’t gonna happen. When I look at movies like Ghost of Mars and Total Recall, my thought is always, how did they get all of those huge buildings and trains and … stuff … there? There is no energy or infrastructure there to take raw materials and make all of that stuff and it would be incredibly expensive to transport all of the stuff you would need there. Yeah, a half dozen people being transported to Mars with enough oxygen and water to do some scientific research is certainly doable, especially if you launch a bunch of rockets with all of their supplies ahead and behind them. Perhaps in some far distant future when we have perfected Fusion power and transporter technology, we can start trying to colonize, but, it just ain’t gonna happen in any of my lifetimes or near-term reincarnations.

No need for plants to create the atmosphere. Just re-start the oxygen generator buildings that are scattered around the surface of Barsoom.

Within the next two thousand years we will have found habitable exoplanets. (“Earth type Worlds”, or “class M planets” on Star Trek.) We will still not have the technology for terraforming. Couldn’t we focus on FEASIBLE technologies instead of whatever Elon Musk is promoting in order to aggrandize himself?

Why would you get an astrobiologist to answer spacecraft design questions? The big rovers can’t be powered via solar panels; they have MMRTGs (nuclear thermoelectric generators).

I have a question here… Is it possible or at least feasable to try to produce some type of “space termite” with the moon regolite and the mars rusted soil to produce some kind of propulsion method, energy production capabilities, or used to transform chemicaly the perchlorate found in Mars?
Thanks!
@ronaldocost4
September 22, 2026 at 9:13 pm
Yes, in principle it’s feasible, but more as experimental biotech and chemical engineering than as a literal “termite”.
But that is basically how space exploration works. Nothing is possible until it is.
@taylorsublett5710
September 22, 2026 at 8:46 pm
Isn’t perchlorate toxic to plants as well? Even if you could get enough water to Mars (BIG if), wouldn’t they also die in the toxic soil? Not to mention just getting freeze dried pretty quick

You just said they had toxins in the soil and then without any proof or explanation you also said that you think they can terraform it in our lifetime?

And how much is Elon Musk paying you?
