Crustal and Time-Varying Magnetic Fields at the Insight Landing Site on Mars

Thorne 1, Mark A. Wieczorek 16, Yanan Yu4, Suzanne E. Smrekar9 and William B. Banerdt 9 Magnetic fields provide a window into a planet’s interior structure and evolution, including its atmospheric and space environ- ments. Satellites at Mars have measured crustal magnetic fields indicating an ancient dynamo. These crustal fields interact with the solar wind to generate transient fields and electric currents in Mars’s upper atmosphere. Surface magnetic field data play a key role in understanding these effects and the dynamo. Here we report measurements of magnetic field strength and direction at the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) landing site on Mars. We find that the field is ten times stronger than predicted by satellite-based models. We infer magnetized rocks beneath the surface, within ~150 km of the landing site, consistent with a past dynamo with Earth-like strength. Geological mapping and InSight seismic data suggest that much or all of the magnetization sources are carried in basement rocks, which are at least 3.9 billion years old and are overlain by between 200 m and ~10 km of lava flows and modified ancient terrain. -

Ich erfuhr erstmals im August 2013 vom Hyperloop-Konzept, als dieses der breiten Öffentlichkeit vorgestellt wurde. Seither habe ich die Entwicklungen rund um dieses neue Verkehrsmittel rege verfolgt. Die Idee eines komplett neuen Verkehrssystems und die dahinterstehende Technologie finde ich besonders reizvoll. Bestehende offene Fragen zur tatsächlichen Machbarkeit, der Sinnhaftigkeit und der Finanzierbarkeit des Systems haben mich dazu bewogen mich mit dem Themenkomplex im Rahmen meiner Diplomarbeit genauer auseinanderzusetzen. Ich möchte mich an dieser Stelle bei meinem Betreuer, Herrn FH-Prof. Dipl.-Ing. (FH) Dipl.- Ing. Frank Michelberger, für seine unkomplizierte und entgegenkommende Betreuung der Arbeit, bedanken Ebenso gilt mein Dank meinen Eltern, die mir mein Studium durch ihre Unterstützung ermöglicht haben. Außerdem möchte ich auch meiner Freundin für ihre Geduld während des Erstellens dieser Arbeit danken. Für das Wecken meines Interesses an der Eisenbahn und für die Unterstützung bei der Erstellung der Arbeit bedanke ich mich abschließend nochmals besonders bei meinem Vater.

Aerobraking to Lower Apogee in Earth Orbit with the Small Payload Orbit Transfer (SPORT™) Microsatellite Vehicle

Bhd. 520 Huntmar Park Drive, Herndon, VA 20170 703-709-2240 x138, [email protected] Abstract. AeroAstro, Inc. and Astronautic Technology Sdn. Bhd. (a Malaysian space company) are commercially developing the Small Payload ORbit Transfer (SPORT) vehicle, which uses advanced earth aerobraking technology to achieve efficient orbit transfer from Geosynchronous-Transfer Orbit (GTO) to Low Earth Orbit (LEO). After being delivered to GTO by a large launch vehicle, such as Ariane, SPORT uses its onboard propulsion system to adjust its perigee altitude to about 150 km. At this altitude, the large deployable aerobrake produces enough drag to reduce the apogee altitude from 36,000+ km to about 1,000 km in approximately 300 orbits. Upon reaching the target apogee altitude, the propulsion system is used to raise the perigee to the desired altitude, thereby allowing SPORT to release its payload. Aerobraking technology enables orbit transfer in a cost-effective manner, reducing the overall mass of the spacecraft by drastically reducing the amount of propellant required to achieve the maneuver. -

Mars Aerocapture/Aerobraking Aeroshell Configurations by Abraham Chavez
Mars Aerocapture/Aerobraking Aeroshell Configurations by Abraham Chavez This presentation provides a review of those studies and a starting point for considering Aerocapture/Aerobraking technology as a way to reduce mass and cost, to achieve the ambitious science returns currently desired What is Aerocapture: is first of all a very rapid process, requiring a heavy heat shield resulting in high g-forces, Descent into a relatively dense atmosphere is suffciently rapid that the deceleration causes severe heating requiring What is Aerobraking: is a very gradual process that has the advantage that small reductions in spacecraft velocity are achieved by drag of the solar arrays in the outer atmosphere, thus no additional mass for a heat shield is necessary. an aeroshell.

He Didn’t Win the Nobel Prize fer Nothin’ (posted by Steven W. Baker / SteveB, June 13, 2012) Just when you might have been thinking that you’re the only sane person on the planet, I present to you one economist who is anything but crazy, though Republicans sure love to claim he is. “Paul Krugman's 13 Best GOP Zingers” by Politico June 11, 2012, (http://www.politico.com/gallery/2012/06/krugmans-13-best-gop-zingers/000196-002352.html) Nobel Prize–winning economist Paul Krugman blasted President Barack Obama on Monday for having “screwed up the line” by saying the private sector is “doing fine,” but the New York Times columnist saves his sharpest barbs for Republicans. 1. "Sometimes you do wonder if these guys are moles, Manchurian candidates for I don't know who, if their real job is to bring down America because they really are doing the best they can.” — May 18, 2012, on CNN's “Martin Bashir,” speaking about House Speaker John Boehner’s and other Republican leaders’ economic policies. 2. “I have a structural hypothesis here. You have a Republican ideology, which Mitt Romney obviously doesn’t believe in. He just oozes insincerity, that’s just so obvious. But all of the others are fools and clowns. And there is a question here, my hypothesis is that maybe this is an ideology that only fools and clowns can actually believe in, and that’s the Republican problem.” — Nov. -
