Honestly, if we find absolute proof that there is no life on Mars, can we make life on Mars? I propose crashing a probe full of extremophile bacteria into polar water ice regions, then burying the probe and opening it underground. Wait for a few years, then check the site. If you have thriving bacteria there then BAM life on Mars.
Of course, we could get in trouble with the Planetary Protection Officer... 18.104.22.168 17:53, 9 January 2019 (UTC)
As it is we are quickly terraforming it to Venus...

- Meh, at worst we are terraforming Earth to Cretaceous levels, and that means we can all start riding dinosaurs. Mathmannix (talk) 17:26, 7 January 2019 (UTC)
- Don't worry, we've been studying how to turn Venus into Earth since 1961 https://en.wikipedia.org/wiki/Terraforming#History_of_scholarly_study . Once our oceans finish boiling away, we'll know exactly what to do. 22.214.171.124 17:56, 7 January 2019 (UTC)
- It seems the most conservative estimates for global warming arr about 2 deg C per 100 years, so our ice should boil before 5,000 years pass. 126.96.36.199 19:24, 7 January 2019 (UTC)
Surely the term should be Martiforming or Areforming? (User:richardelguru)
- Earth / Earthling / Terra / Terran / Terraforming ... Mars / Martian / Marsiforming perhaps? Stop Earthiforming all those lovely desolate space rocks! I'm trying to build a new species that thrives off of harsh interstellar environments and you're destroying its ecosystem! 188.8.131.52 17:56, 7 January 2019 (UTC)
- This was proposed for Mars terraforming, to increase the temperature of the planet and melt the CO2 glaciers. On Earth, they would be to reflect light without absorbing it, so that the temperature of the planet drops, I suppose. https://en.wikipedia.org/wiki/Terraforming_of_Mars#Use_of_orbital_mirrors 184.108.40.206 18:52, 7 January 2019 (UTC)
- Space mirrors were also proposed for Venus terraforming to alter the day-night cycle to be more similar to ours. https://en.wikipedia.org/wiki/Terraforming_of_Venus#Space_mirrors 220.127.116.11 19:17, 7 January 2019 (UTC)
To really change Earth to be either like Venus or Mars we need to get rid of the magnetic field that stops the solar wind stripping the atmosphere away. Once that is depleted the oceans will evaporate so that the solar wind can strip that away as well. Whether Earth then freezes or boils would depend on surface rocks and volcanic activity levels. One option to stop the magnetosphere would be to de-orbit the Moon, thus re-amalgamating it with the Earth and getting lots of vulcanism going. RIIW - Ponder it (talk) 20:12, 7 January 2019 (UTC)
- That would make the Earth more like Mars, but not at all like Venus. Venus has a rather thick atmosphere. 18.104.22.168 13:48, 8 January 2019 (UTC)
It's a shame this strip wasn't accompanied with a "What If" entry about what it would actually take to make Earth resemble Mars. 22.214.171.124 15:56, 12 January 2019 (UTC)
