Methane, Ammonia on Mars? Mariner 7 Sees Hint of Life

(8.August 1969)

Pimentel´s evidence was from an infrared spectrometer, designed to detect elements by measuring their radiation.

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.

Is there methane on Mars?

(2011)

The first discovery of methane on Mars was announced in 1969 at a press conference by the Mariner 7 Infrared Spectrometer (IRS) team just two days after the flyby.

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.

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.

A Gloomy Mars Warms Up

(14.05.2007)

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.

Mars: Sonde „Insight“ zeichnet erstmals Geräusche des Planeten auf

„Insight“ ist ein 360 Kilogramm schwerer Roboter, der nicht rollt, sondern an einem Ort bleibt. Die insgesamt rund 650 Millionen Euro teure Mission ist auf zwei Jahre angelegt.

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.

Liftoff of InSight

A United Launch Alliance Atlas V rocket lifts off at 4:05 a.m. PDT (7:05 a.m. EDT) from Space Launch Complex 3 at Vandenberg Air Force Base in California carrying NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, or InSight, Mars lander. InSight will be the first mission to look deep beneath the Martian surface. It will study the planet’s interior by measuring its heat output and listen for marsquakes.

WATCH LIVE: NASA launches InSight Lander to Mars

InSight, which stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, will be the first lander or rover bound for Mars since Curiosity launched in 2011. It will also be the first to dig deep into the planet’s interior in an effort to understand how the planet’s geology evolved over billions of years. The probe will scan for seismic activity, keeping tabs on the planet’s so-called “marsquakes.”

NASA-Mission: „InSight“ auf dem Weg zum Mars

Dafür hat die Deutsche Gesellschaft für Luft- und Raumfahrt (DLR) ein Messgerät entwickelt, das bis zu fünf Meter unter die Oberfläche des Planeten vordringen kann. Außerdem sollen Marsbeben vermessen werden. Die kleine Rammsonde der DLR soll sich automatisch fünf Meter tief in den Marsboden hämmern und in unterschiedlichen Tiefen die Temperatur und die Wärmeleitfähigkeit messen.
