Curiosity rover captures highest-resolution panorama photo of Mars ever taken

Scientists have spent the last few months assembling the nearly 1,200 images to create one cohesive picture, NASA said in a press release. They were taken with the rover’s Mast Camera, or Mastcam, using its telephoto lens between November 24 and December 1, when the entire mission team on Earth was off for Thanksgiving.

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).

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

(14.03.2019)

„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.

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.

Der Mond als Marktplatz

Jarzombek wiederum hat die Forcierung eines Weltraumgesetzes angekündigt, das die Haftungsrisiken der Weltraumindustrie mindern soll, etwa bei Schäden, die durch Fehlstarts oder Satellitenkollisionen entstünden. Ziel der Gesetzesinitative sei es, „dass unsere Regeln nicht schlechter sind als die anderer europäischer Länder“, erklärt der Raumfahrtkoordinator der Bundesregierung. Jarzombek schwebt eine Art „Space-Hermes“ vor: „Eine Versicherung nach dem Muster der staatlichen Hermes-Exportkreditversicherung.“

Mars Cube One Demo

All previous CubeSats have orbited the Earth. MarCO is the first attempt to go to another planet. By verifying that the technologies for interplanetary missions are feasible and can be developed on a short timeline, this test mission could lead to many other SmallSat applications for exploring our solar system. Some could provide similar support functions as „carry your own“ relay providers. Others could have primary scientific research functions of their own, such as radio transmissions through planetary atmospheres, imaging with small cameras, observations with other miniaturized instruments, or in-place measurements of space environments.
