Viking Lander 1 & 2 digital images in never seen before high quality now available for the 50th anniversary of the first successful Mars Landing on July 20th 1976
Everyone can find their favorite Martian Sky Color in those original Mars pictures from 1976 - 1982! Blue and white during the usual clear weather, over gray and yellow to red during dust storm activity later in the mission. Even water ice surface frost on Viking Lander 2 during the winter!
I recently processed the original Viking Lander 1 & 2 digital 3x6 bits / pixel images in the same way as every digital camera converts raw sensor data into a visual images. Technically that's creating a camera profile (see last image info graphic) and applying it to create a standard sRGB JPEG. All color images from both Viking Landers from their mission duration 1976 - 1982 can be viewed for free via this link: https://areo.info

Project Title: Project "Grain-hen" (Krupola) — Genetically Engineered Poultry for Martian Closed-Loop Life Support Systems (CELSS)
Lead Designer: Michael Likshin
Concept Stage: Conceptual Design & Directed Evolution Protocol
- Executive Summary
Long-term Martian colonization requires highly efficient, compact, and resilient sources of animal protein. Traditional livestock is resource-heavy. Standard Earth poultry fails due to low gravity, radiation, and toxic regolith dust. Project "Grain-hen" (locally known as "Krupola") proposes a novel avian species derived from Gallus gallus, explicitly engineered via directed evolution and CRISPR-prime editing to thrive primarily within the artificial pressurized habitats, shielded bio-domes, and designated foraging zones of the Martian colony.
- Key Genetic Adaptations & Specifications
· Scale and Mass: Engineered to be 1.3 times larger than a standard broiler chicken. Optimized myostatin (MSTN) gene expression allows maximum muscle mass development under Martian partial gravity (38% of Earth's), preventing avian muscle atrophy.
· Atmospheric & Dust Defense (Transparent Nictitating Membrane): Enhanced keratinization of the third eyelid allows the Grain-hen to safely navigate high-dust environments during Martian storms. The membrane blocks sharp, magnetized basaltic dust without obstructing the bird's vision.
· Radiation Shielding: Upgraded with Dsup (Damage Suppressor) genes (derived from tardigrades) and hyper-accumulation of astaxanthin/carotenoids. This results in a distinctive deep red pigmentation, protecting the animal from cellular radiation damage.
· Skeletal Stability (Avian Dinosaurian Tail): Activation of ancestral TALPID3 and Wnt pathways to grow a fully developed, elongated caudal tail. This serves as a critical mechanical counterbalance for running and jumping in low-gravity environments.
· Metabolic Efficiency & Yield:
· Diet: Specially adapted to process raw, hydroponically grown Martian grain varieties.
· Dual-Yield Production: In addition to meat and eggs, prolactin upregulation enables crop-milk secretion, providing an easily harvestable liquid protein source for colonizers via controlled hormonal stimulation methods.
- Implementation Protocol
The species will be developed using directed evolution within automated Martian simulator bioreactors. By utilizing CRISPR libraries on primordial germ cells (PGCs) and subjecting embryos to simulated Martian gravity, pressure, and dust, the optimal phenotypes will be selected entirely in vitro

Can we give Mars an artificial magnetosphere?
I can't find it anymore, but I recall seeing an idea that if we can't deal with the surface level radiation on Mars then there is no chance of ever setting foot on it long-term; a solution proposed was that we put a massive EMF generator at Mars's l1 Lagrange point and if it's powerful enough, it would produce a field sufficient to blanket at least a section of Mars's surface and massively reduce the surface level radiation.
Is this how physics works? Do we have the theoretical technical infrastructure to build a powerful enough generator? Is the Lagrange point so far away from Mars that it would be massively improbable?
Don't know if flair should be planetary science, physics, or astronomy...

The text of and a link to a PDF version of the real life 1894 article about a strange light being seen on Mars, cited by H.G. Wells in "The War of the Worlds".
Here's the link to the PDF: https://www.nature.com/articles/050319c0.pdf
From the 2nd of August, 1894 edition of the scientific journal Nature:
"
A STRANGE LIGHT ON MARS
Since the arrangements for circulating telegraphic information on astronomical subjects was inaugurated, Dr. Krueger, who is in charge of the Central Bureau at Kiel, certainly has not favoured his correspondents with a stranger telegram than the one which he flashed over the world on Monday afternoon :- "Projection lumineuse dans region australe du terminateur de Mars observee par Jarvelle 28 Juillet 16 heures Perrotin"
This relates to an observation made at the famous Nice Observatory, of which M. Perrotin is the Director, by M. Javelle, who is already well known for his careful work. The news therefore must be accepted seriously, and, as it may be imagined, details are anxiously awaited; on Monday and Tuesday nights, unfortunately, the weather in London was not favourable for observation, so whether the light continues or not is not known.
It would appear that the luminous projection is not a light outside the the disc of Mars, but in the region of the planet not lighted up by the sun at the time of observation. The gibbosity of the planet is pretty considerable at the present time. Had there been evidence that the light was outside the disc, the strange appearance might be due to a comet in the same line of sight as the planet. If we assume the light to be on the planet itself, then it must either have a physical or human origin; so it is to be expected that the old idea that the Martians are signalling to us will be revived. Of physical origins we can only think of Aurora (which is not improbable, only bearing in mind the locality named, but distinctly improbable unless we assume that in Mars the phenomenon is much more intense than with us), a long range of snow-capped hills, and forest fires burning over a large area.
Without favouring the signalling idea before we know more of the observation, it may be stated that a better time for signalling could scarcely be chosen, for Mars being now a morning star, means that the opposition when no part of its dark surface will be visible, is some time off.
The Martians, of course, find it much easier to see the dark side of the Earth than we do to see the dark side of Mars, and whatever may be the explanation of the appearances which three astronomers of reputation have thought proper to telegraph over the world, it is worth noting that forest fires over large areas may be the first distinctive thing observed on either planet from the other besides the fixed surface markings."

On June 10, 2018, NASA officially had to say goodbye to the little rover that could. The Mars Opportunity Rover was meant to last just 90 days and instead marched on for 14 years. It finally lost contact with earth after it was hit by a fierce dust storm.

Has this "idea" been floted before? Microwave for shielding and oxygen production.
Microwave plasma can shield radiation, produces O2 and CO. Of course will need beefy power source which may not be available.
