NASA images show a meteor crashed into Mars, triggered a big quake, and kicked up surprise water ice
A meteor crashed into Mars on Christmas Eve 2021, and shook the planet so much that NASA‘s InSight lander recorded the rumblings.
Scientists didn‘t know where the quake came from until NASA‘s Mars Reconnaissance Orbiter, a spacecraft circling the red planet, captured images of the new impact crater. NASA revealed the discovery on Thursday.
Earth and Mars: Evolution of Atmospheres and Surface Temperatures
(7. Juli 1972)
Indeed, detailed global climatic models (17) suggest that a relative increase in A of only 2 percent is enough to induce extensive glaciation on Earth, which implies that the present climate is extremely sensitive to albedo. This leaves changes in atmospheric composition as a possible explanation. Major variations in the CO2 abundance will have only minor greenhouse effects because the strongest bands are nearly saturated. A change in the present CO2 abundance by a factor of 2 will produce directly a 2° variation in surface temperature (18). The CO2 abundance is highly controlled by silicate-carbonate equilibria; by buffering with seawater, which contains almost 100 times the atmospheric CO2; and by the respiration and photosynthesis feedback loop (19).
China‘s Tianwen-1 probe sends back Mars landing visuals

Zhurong Rover is driving on Mars sending back new images (Chinese Tianwen-1 mission)
On May 21, 2021 CNSA published images of Mars Rover Zhurong driving on Red Planet around general station. The rover‘s mission planned tasks are to: Study the topography and geology of the local area; examine the soil and any ice content; survey the elements, minerals and rocks; atmospheric sampling.
Since the @NASAPersevere landing, we’ve been prioritizing two types of data: first-of-its-kind footage from the rover’s entry, descent & landing. And, health & safety data for the rover & its subsystems. We’ll release more images & video on Monday in a news briefing at 2pm ET.

NASA’s Mars Helicopter Reports In
f Ingenuity succeeds in taking off and hovering during its first flight, over 90% of the project’s goals will have been achieved. If the rotorcraft lands successfully and remains operable, up to four more flights could be attempted, each one building on the success of the last.
“We are in uncharted territory, but this team is used to that,” said MiMi Aung, project manager for the Ingenuity Mars Helicopter at JPL.

Solar Rotation Effects on The Thermospheres of Mars and Earth
(spring 2006)
The first thing that must be understood in this paper is the chain of events that is being tracked. From the Sun‘s rotational quirks, to their effects on CO2 in the respective atmospheres of Mars and Earth. There is also a comparison to older, normalized data from Venus.
(…)
Interestingly, once the data was compiled, there was no correlation found between the levels of CO2 found in the upper atmosphere (~150km on Earth, where this transformation takes place.) Broadening their search, the authors found a strong correlation between the ratio of CO2/O2 and the thermal changes. They feel this suggests that the thermal diffusion effect relies on some form of resonance between the two molecules involved

Magnetic Flux Ropes in the Martian Atmosphere: Global Characteristics
(März 2004)
We report observations of magnetic fields amplitude, which consist of a series of individual spikes in the Martian atmosphere. A minimum variance analysis shows that these spikes form twisted cylindrical filaments. These small diameter magnetic filaments are commonly called magnetic flux ropes. We examine the global characteristics of magnetic flux ropes, which are observed on 5% of the elliptical orbits of Mars Global Surveyor.
Close Comet Flyby Threw Mars’ Magnetic Field Into Chaos
(09.03.2016)
And like a solar storm, the comet’s close passage likely fueled a temporary surge in the amount of gas escaping from Mars’ upper atmosphere. Over time, those storms took their toll on the atmosphere.
“With MAVEN, we’re trying to understand how the sun and solar wind interact with Mars,” said Bruce Jakosky, MAVEN’s principal investigator from the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder. “By looking at how the magnetospheres of the comet and of Mars interact with each other, we’re getting a better understanding of the detailed processes that control each one.”

The Curiosity rover detects oxygen behaving strangely on Mars
„We‘re struggling to explain this,“ said Melissa Trainer, study author and planetary scientist at NASA‘s Goddard Space Flight Center. „The fact that the oxygen behavior isn‘t perfectly repeatable every season makes us think that it‘s not an issue that has to do with atmospheric dynamics. It has to be some chemical source and sink (of elements into the soil) that we can‘t yet account for.“
It relates back to the methane mystery.
Is this how we‘ll live on Mars?
„The climate crisis is — rightly — frightening a lot of people, and there is a tendency to think of Mars as a sort of escape hatch for humanity, a planet B, which is very dangerous and problematic,“ said Watson.

Strong planetary magnetic fields like Earth‘s may protect oceans from stellar storms

„Magnetic fields appear to play an essential role in making planets habitable, so I wanted to find out how Earth‘s magnetic field compared to those of other potentially habitable planets,“ she said.
Ms McIntyre said Earth‘s strong magnetic field had probably played an important role in protecting the atmosphere from the solar wind and keeping the planet wet and habitable.
„Venus and Mars have negligible magnetic fields and do not support life, while Earth‘s magnetic field is relatively strong and does,“ she said.
Unlike Earth, Mars does not have a magnetic field to shield its atmosphere from solar wind:

What Does a Marsquake Look Like?
(22.07.2019)
Provided by the French space agency, Centre National d‘Études Spatiales (CNES), the seismometer detected its first marsquake on April 6, 2019. The InSight mission‘s Marsquake Service, which monitors the data from SEIS, is led by Swiss research university ETH Zurich.
NASA‘s InSight Detects First Likely ‚Quake‘ on Mars
(23.04.2019)
The faint seismic signal, detected by the lander‘s Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander‘s 128th Martian day, or sol. This is the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind. Scientists still are examining the data to determine the exact cause of the signal.

They discovered that a wind-whipped, dusty surface has a measurable effect on the amount of sunlight that is reflected by the planet. The results of this research show that an increase in darkened surface areas may account for a one degree Fahrenheit rise in the surface air temperature of the planet.
First Likely Marsquake Heard by NASA‘s InSight
This video and audio illustrates a seismic event detected by NASA‘s InSight on April 6, 2019, the 128th Martian day, or sol, of the mission. Three distinct kinds of sounds can be heard, all of them detected as ground vibrations by the spacecraft‘s seismometer, called the Seismic Experiment for Interior Structure (SEIS): There‘s noise from Martian wind; the seismic event itself; and the spacecraft‘s robotic arm as it moves to take pictures.

NASA unveils new goals for Moon, Mars, including space privatization
(1.10.2018) These certainly mean more dollars headed toward research and development; while the original Apollo and other missions were government-funded and ultimately fell under the purview of the military (indeed, one of the primary stated goals of the Gemini and Apollo programs was to lessen the „Missile gap“ between the United States and the Soviet Union), this new concept relies heavily on private investment, corporate involvement and funding, and the eventual mining and financial rewards of „exploration and use“ of the lunar and Mars surfaces.
