Methan auf Mars muss kein Hinweis auf Leben sein

Als der im Sommer 2012 im Rahmen der Nasa-Mission „Mars Science Laboratory“ im Gale-Krater abgesetzte Rover Curiosity Ausbrüche des Gases Methan registrierte, und mehr noch, als die Messungen mit dem Laser-Spektrometer an Bord des Robotfahrzeugs jahreszeitliche Schwankungen des Methan-Anteils in der dünnen Mars-Atmosphäre zeigten, gerieten die Forscher auf der Erde in Aufregung. Denn auf der Erde deutet so etwas zumeist auf biologische Aktivität…

Amidst Cuts to NASA, Mars Sample Return May Finally Happen

The President’s Budget Request for NASA in 2020 would start a Mars Sample Return mission and ramp up efforts to send humans to the Moon. But it would still kick off the first year of a new decade with a half-billion dollar cut to the space agency.

SwRI-led LAMP instrument sheds light on lunar water movement

Using the Southwest Research Institute-led Lyman Alpha Mapping Project (LAMP) aboard NASA’s Lunar Reconnaissance Orbiter (LRO), scientists have observed water molecules moving around the dayside of the Moon. A paper published in Geophysical Research Letters describes how LAMP measurements of the sparse layer of molecules temporarily stuck to the surface helped characterize lunar hydration changes over the course of a day. Up until the last decade or so, scientists thought the Moon was arid, with any water existing mainly as pockets of ice in permanently shaded craters near the poles. More recently, scientists have identified surface water in sparse populations of molecules bound to the lunar soil, or regolith. The amount and locations vary based on the time of day. This water is more common at higher latitudes and tends to hop around as the surface heats up.

BR News – Einblick in das Innerste des Mars

Noch ist der NASA-Lander Insight auf dem Weg zum Mars. Ende November soll er dort ankommen und darauf Platz nehmen. Dieses Rendezvous wird dem Roten Planeten tatsächlich unter die Haut gehen. Die NASA ist dem Mars bereits mehrfach zu Leibe gerückt – unter anderem mit den Rovern Opportunity und Curiosity sowie den Sonden Odyssey, MRO und Maven. Am 5. Mai 2018 wurde der stationäre Lander InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) zum Schnüffeln losgeschickt. InSight startete mithilfe einer rund 57 Meter großen Atlas-V-401-Rakete von der Vandenberg Air Force Basis in Kalifornien und soll am 26. November auf dem Roten Planeten ankommen. Dann wird der Lander für rund zwei Jahre zum geduldigen Spürhund.

Nasa’s InSight mission will target ‚Marsquakes‘

InSight will be the first probe to focus its investigations predominantly on the interior of the Red Planet. The lander – due to touch down in November – will put seismometers on the surface to feel for „Marsquakes“. These tremors should reveal how the underground rock is layered – data that can be compared with Earth to shed further light on the formation of the planets 4.6 billion years ago. „As seismic waves travel through [Mars] they pick up information along the way; as they travel through different rocks,“ explained Dr Bruce Banerdt, InSight’s principal investigator. „And all those wiggles you see on seismograms – scientists understand how to pull that information out. After we’ve gotten many, many Marsquakes from different directions, we can put together a three dimensional view of the inside of Mars.“

The InSight mission logbook

Logbook entry: 12 March 2019
This week the radiometer has observed three passes of Phobos in front of the Sun: Phobos eclipses. The eclipses were pronounced in the radiometer data showing an approximately 1°C dip in temperature through the roughly 30 seconds of duration of the eclipse. The cameras on InSight have also observed the small and brief dip in daylight as can be seen in the animated gif below. The radiometer data will be interpreted in terms of the thermo-physical properties of the top-most layers of the Martian soil. Interpretations of the results are expected by the time of the Lunar and Planetary Science Conference earliest, which is from 18 to 22 of March.

NASA InSight lander catches a shadowy eclipse on Mars

NASA’s InSight has its Mars plate full with deploying the lander’s seismometer and trying to figure out why its heat probe is having problems digging down. But it still had time for some sightseeing when it documented an eclipse.

InSight’s Deck Camera Observes Phobos Eclipse

NASA’s InSight lander took this series of images on Wednesday, March 6, 2019, capturing the moment when Phobos, one of Mars‘ moons, crossed in front of the Sun and darkened the ground around the lander. These images were taken by InSight’s Instrument Context Camera (ICC), located under the lander’s deck.

Ice Road Trucker in Kanada, sinnbildlich „am Ende der Welt“, sind mit ihren tonnenschweren LKW auf den zugefrorenen Seen im kanadischen Nordwesten dank zahlreicher TV-Auftritte auch in Deutschland bekannt. Die Eisstraßen stehen nur wenige Wochen im Jahr zur Verfügung. In dieser Zeit werden tausende Tonnen Material über die „Eisautobahn“ bewegt, denn die vereisten Seen bieten im Winter als saisonale Straßen die Möglichkeit, abgelegene Gemeinden und Industrien in den kalten Regionen effektiv und wirtschaftlich effizient zu erreichen.

SLS Buyer’s Remorse At NASA

Two sources familiar with the thinking of Vice President Mike Pence–who leads US space policy–have said he is frustrated with the slow pace of the nation’s efforts to send humans to the Moon. In particular, he is growing tired of delays with NASA’s Space Launch System rocket, which was originally due to launch in 2017 and is now likely delayed until 2021 at the earliest. ..

Is SLS Going To Be The Biggest Rocket – Evah?

Keith’s note: Let’s see: Saturn V was 363 feet tall and weighed 6,540,000 lb. SLS Block 1 (the only rocket this budget supports) is 322 feet tall for crew version and 313 feet tall for the cargo version and weighs 5.5. million lb. SLS Block 1 can put 209,000 lb in to LEO and Saturn V could put 310,000 lb into LEO. Oh yes a totally expendable Falcon Heavy can put 141,000 lb into LEO.

Apollo 9: Der erste bemannte Einsatz der Mondlandefähre vor 50 Jahren

Anfang März 1969, vor fünfzig Jahren, wurde von der Nasa mit Apollo 9 die vorletzte Mission vor derjenigen umgesetzt, die als Apollo 11 die ersten Menschen auf den Mond bringen würde. Die Rolle von Apollo 9 war für die spätere Mondlandung zentral: Zum ersten Mal sollte der bemannte Einsatz der Mondlandefähre getestet werden, die einige Monate später Neil Armstrong und Buzz Aldrin von dem um den Mond kreisenden Apollo-Mutterschiff auf die Mondoberfläche und zurück transportieren sollte.
