Hungarian Researchers Claim to See Biosignatures in Martian Meteorite

[link]

Dr. Gyollai and co-authors analyzed a thin section of ALH-77005 by optical and FTIR-ATR microscopy.

They were able to detect the presence of coccoidal and filamentous structures (probably built by iron-oxidizing microbes); organic material; biogenic minerals, like ferrihydrite, goethite, and hematite.

Mars Soil For Science Fairs

Hello Fellow Space Explorers

This is my version of Martian regolith simulant JSC MARS-1A.

Martian regolith simulant (or Martian soil simulant) is a terrestrial material that is used to simulate the chemical and mechanical properties of Martian soil for research and experiments

After the Viking landers and the Mars Pathfinder’s rover landed on Mars, the onboard instruments were used to determine the properties of the Martian soil at the landing sites. The studies of the Martian soil properties led to the development of JSC Mars-1 Martian regolith simulant at NASA’s Johnson Space Center in 1998

Using NASA’s soil analysis I formulated my own Mars simulant for my son to use in a Mars science fair project.

The five most abundant ingredients in Mars soil account for almost 95% of the soil. The other 5% is made up of several tiny rare elements that are not easily attainable outside of NASA.

My Mars soils percentages are adjusted to compensate for the 5 % unattainable materials

SiO2 – 54.5%
Fe2O3 – 20.9%
Al2O3 – 8.2%
MgO – 8.7%
CaO – 7.7%

I mix my Mars soil in a clean lab and UV sterilize each batch before and after packing into one pound ziplock bags.

Fare well

Looks like its over. Many people have been posting here for more than a decade. Some who were here from the beginning are no longer with us. As a scientist I found it doubtful that any part of us continues to exist in some form after we are gone, but if it does, is it not so for the rovers? And if that can be, perhaps there is some metaphysical corner of existence where they all live on together.

So long and thanks for all the fish.

Rover Robot equipment

Hi guys, do any of you know anything about Rover Robot ChemCam and other instruments they use on Mars? I am doing a research as part of my studies and I have a short questionnaire I would be thankful if anyone could fill it out for me! Here is the link for it https://goo.gl/forms/rWFdMZUfKwZM7tbu1

Jezro Station

As it will be future known, hubcap city, Mars Recon Base.....don't know when....civilian not military....military presence,, political NO......science base,, comments welcome....probably see this in the mid to late 20's
Points>>:
Location
Relatively Flatland
Diverse Strata
Other?

Bandwidth

As I woke up the other night,rolled over and saw Mars perfectly centered in my window. I got to wondering, I think nasa and jpl don't take much video on mars because it's so hard to get it back here given the structure in place as far as satellites go. I wonder if when man steps forth on mars for the first time we are only going to get still photos updated every 5 seconds or so ?

Navigation

Do the rovers use visuals to navigate at all aside from sending images to Earth, analyzed and then commands returned?

Navigation

Do the rovers use visual means to navigate themselves at all or is it from images sent to Earth which are then looked at by scientists and commands returned?

The Great Faceless Challenge

Faceless, please post all visible evidence of Man`s time on Mars here. All Images and analysis must be posted here. Reference all data and supply context images for all crops on demand.

Microbial life on Mars seems likely. Any visible data, analysis post here. Any context on demand.

Rules : no links, just you, me and the forum.
