The mission launched on 5 May 2018 at 11:05 UTC aboard an Atlas V-401 rocket and successfully landed at Elysium Planitia on Mars on 26 November 2018 (205/6 months) at 19:52:59 UTC.
How long will a trip to mars take? (estimates range from 130-260 days)
InSight traveled 483 million km (300 million mi) during its journey.
InSight‘s objectives are to place a seismometer, called SEIS, on the surface of Mars to measure seismic activity and provide accurate 3D models of the planet’s interior; and measure internal heat flow using a heat probe called HP3 to study Mars’ early geological evolution. This could bring a new understanding of how the Solar System’s terrestrial planets – Mercury, Venus, Earth, Mars – and Earth’s Moon form and evolve.
One thing is for sure: it is 1000x time easier to survive / farm the desert of Gobi than on Mars, why? Because Earth got a magnetic shield… is it possible to install a Magnetic Shield Generator “in front of” Mars?
What could grow on Mars?
“The Great Oxygenation Event on Earth 2.45 billion years ago was caused by cyanobacteria.” (src)
2012: “Alpine and polar lichens could also survive on Mars. Planetary researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) simulated the conditions on Mars for 34 days and exposed various microorganisms to this environment. “During this period, the lichens and bacteria continued to demonstrate measurable activity and carry out photosynthesis,” says Jean-Pierre de Vera, a scientist at the DLR Institute of Planetary Research in Berlin and head of the Mars simulation project. The microorganisms adapted to this environment, primarily in niches in rocks and in fissures and gaps in the simulated Martian soil. This might be an indication that such adaptation strategies would make life possible in niches on the actual surface of Mars as well.
Do not forget about Earth!
It is still clever to care about the environment earth – because it buys us time – time that is needed to become a multi-planetary species – increasing mankind’s survive-ability in the universe. (one nuclear war/meteor/volcano could hurt mankind just as the dinosaurs)
But we should try to colonize Mars – not because it is easy or because it is rational – but because it is a challenge and mankind is way less rational as “homo sapiens” thinks.
The Problem: we are irrational
maybe a little irrationality enthusiasm is good if you wanna go to Mars 🙂
achievements were done – not because they are easy – because we thought it’s cool that they will happen within our lifetime 🙂
I sincerely hope – we manage to colonize Mars within my lifetime.
Terra-forming: Energy and Solar Winds
Actually all you need is a sustainable energy source? (wind & solar & batteries & maybe 1-2 nuclear backups?).
With energy you can melt the ice – use it as drinking water (will have to add minerals) – clean/rinse the soil of the toxic perchlorates and use it for farming – at the same time CO2 should bubble from the soil.
Maybe the most important thing: Either have drilling equipment – to build your greenhouse underground – maybe with windows that filter the “bad radiation” but then it would get covered in dust fast anyway – because of it’s lack of Magnetic Shield – stellar radiation will kill everything – even plants: a Magnetic Shield Generator.
NASA plans exactly that… but not on Mars:
- actually there are other approaches and hope they will become more practical over time and hope that the combination of space agencies and governments come together and are willing to build it…
new approach: Did you know that it “only” takes a 3400km cable around Mars to establish a artificial protective magnetic field around Mars, that would make Mars’ atmosphere thicken over time, without it, every new CO2 molecule would be blasted away by solar winds (and lost).
“As a result, Mars atmosphere would naturally thicken over time, which lead to many new possibilities for human exploration and colonization.
According to Green and his colleagues, these would include an average increase of about 4 °C (~7 °F), which would be enough to melt the carbon dioxide ice in the northern polar ice cap.
This would trigger a greenhouse effect, warming the atmosphere further and causing the water ice in the polar caps to melt.
By their calculations, Green and his colleagues estimated that this could lead to 1/7th of Mars’ oceans – the ones that covered it billions of years ago – to be restored.” (src)
simulations say: it could work!
The answers, he suggests, lie much deeper than the nuclear-powered Mars Curiosity rover has drilled to date.
Part of the problem, according to McKay, is that geologists are setting the Mars exploration agenda and that astrobiology is not a top priority.
Having spent 30 years searching for signs of what he calls a second genesis — life originating from processes separate from what is known to have occurred on Earth — he now senses that the answer won’t come in his lifetime.” (src)
Mars probably had a lot more water 4 billion years ago
Terra-forming Mars from Red to Blue to Green: Where is the nitrogen?
“Nitrogen is essential for all known forms of life, since it is used in the building blocks of larger molecules like DNA and RNA, which encode the genetic instructions for life, and proteins, which are used to build structures like hair and nails, and to speed up or regulate chemical reactions.” (src)
Earth’s Atmosphere consists of 80% nitrogen (78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere) (src)
Mars’ has only 0.6% of Earth’s mean sea level pressure – it’s atmosphere consists of approximately 96% carbon dioxide, 1.9% argon, 1.9% nitrogen, and traces of free oxygen, carbon monoxide, water and methane, among other gases,.(src) So plants should “Yeeha” because they love CO2 – but they don’t love DNA destructive space radiation also hitting Mars’ surface almost unhindered.
and a magnetic shield – but it’s core cooled down and the dynamo effect that creates Earth’s magnetic shield against solar radiation – got lost.
Mars 2020 rover is an astrobiology will clarify on that.
“Apollo Program experience warns that opening an EVA hatch directly to the surface will bring dust into the ascent vehicle.”
“There are at least seven functional requirements that must be considered for a minimum functional tunnel that helps returning Mars crews comply with planetary protectionprotocols. The mass of a minimum functional tunnel for MAV ingress is estimated to be about 237 kg, not including mass growth allowance or a tunnel inflation system. Preliminary analysis indicates that an inflatable tunnel trades more favorably for mass than suitports in this application, but additional forward work is necessary to refine the concept and assess other alternatives.”
“Although not necessarily a practical solution, this “one job, one time” minimal functional baseline configuration will serve as a starting point from which to evaluate MAV ingress alternatives, or to measure the mass penalties as additional functionality is added.” (https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20160001028.pdf)

“Dr Christopher McKay: “If we can’t find life in the Atacama Desert (50x times drier than death valley) we are not ready to search for life on Mars”: CyanoBacteria
Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, are a phylum of bacteria that obtain their energy through photosynthesis, and are the only photosynthetic prokaryotes able to produce oxygen.
“Cyanobacteria are aquatic and photosynthetic bacteria that have been hugely important in shaping the course of evolution and the content of the Earth’s atmosphere. The oxygen rich atmosphere upon which we depend, was generated by vast numbers of newly arisen photosynthetic cyanobacteria during the Archaean and Proterozoic Eras.” (src)
Radiation destroys DNA – Cyanobacteria can self-repair it’s DNA:
Cyanobacteria are challenged by environmental stresses and internally generated reactive oxygen species that cause DNA damages. Cyanobacteria possess numerous E. coli-like DNA repair genes. Several DNA repair genes are highly conserved in cyanobacteria, even in small genomes, suggesting that core DNA repair processes such as recombinational repair, nucleotide excision repair and methyl-directed DNA mismatch repair are common among cyanobacteria.
Volcanic Rocks on Mars?
“The spectrum that we’re seeing was not what I expected,” said APXS principal investigator Ralf Gellert of Canada’s University of Guelph.
“It seems to be a new type of rock that we’ve discovered on Mars” that wasn’t seen by NASA’s previous Mars rovers Spirit and Opportunity.
Jake appears to have higher concentrations of elements such as
- Sodium chloride is extensively used for anti-icing and de-icing and as a preservative; examples of the uses of sodium bicarbonate include baking, as a raising agent, and sodablasting. Along with potassium, many important medicines have sodium added to improve their bioavailability; though potassium is the better ion in most cases, sodium is chosen for its lower price and atomic weight. Sodium hydride is used as a base for various reactions (such as the aldol reaction) in organic chemistry, and as a reducing agent in inorganic chemistry.
- lower concentrations of magnesium
- nickel, than other igneous rocks studied on Mars.
While previously unknown on Mars, this type of chemical composition is seen in a rare but well-studied class of rocks on Earth. On Earth, such specimens are found on oceanic islands such as Hawaii and in other places.
They are thought to form when interior rocks melt to form magma, which then rises toward the surface.
As it rises, it cools, and parts of the material crystalize, preferentially selecting some elements while leaving a remainder of liquid magma that is enriched with the left-behind chemicals. (src)
