Abstract The mineralogy of comet 81P/Wild 2 particles, collected in aerogel by the Stardust mission, has been determined using synchrotron Fe‐K X‐ray absorption spectroscopy with situ transmission XRD and fluorescence, plus complementary microRaman analyses. Our investigation focuses on terminal grains eight tracks: C2112,4,170,0,0; C2045,2,176,0,0; C2045,3,177,0,0; C2045,4,178,0,0; C2065,4,187,0,0; C2098,4,188,0,0; C2119,4,189,0,0; C2119,5,190,0,0. Three have identified as near pure...
The TOPEX/Poseidon radar altimeter satellite applies advances in remote sensing instrumentation to reduce long wavelength measurement errors dramatically lower levels. TOPEX measures the range ocean surface with 2-cm precision and accuracy through use of both Ku- C-band radars, a high pulse repetition frequency, an agile tracker, absolute internal height calibration. Dual bandwidths for frequencies make it possible quickly acquire begin tracking after crossing land/ocean boundary....
A third generation satellite radar altimeter to be flown on the SEASAT-A mission in 1978 is described. Building SKYLAB and GEOS-C experience, a design has evolved that will allow long-term goal of 10-cm altimetry realized. While dependent recent developments surface acoustic-wave device technology, all other respects presents no major difficulty. linear FM/full-deramp waveform processing technique allows fine range tracking done frequency domain. digital filter bank provide 60 contiguous...
Abstract The Lost Meteorites of Antarctica project was the first UK‐led Antarctic meteorite recovery expedition. has successfully confirmed two new high‐density stranding zones in Hutichison Icefield and Outer Recovery Icefields areas investigated geology three previously unvisited nunataks (Turner Nunatak, Pillinger Halliday Nunatak). undertook searching on ice surface via skidoo reconnaissance systematic developed a novel pulse induction metal detection system to search for englacial...
Martian meteorite Northwest Africa (NWA) 8114 – a paired stone to NWA 7034 provides an opportunity examine the thermal history of martian regolith and study near-surface processes ancient environmental conditions near impact crater on Mars. Our reports petrographic alteration textures focuses pyroxene iron oxide grains. Some clasts show exsolution lamellae, indicating high temperature magmatic origin slow cooling. However, transmission electron microscopy reveals that other predominantly are...
MARS2013 was an integrated Mars analog field simulation in eastern Morocco performed by the Austrian Space Forum between February 1 and 28, 2013. The purpose of this paper is to discuss system data processing utilization adopted Remote Science Support (RSS) team during mission. RSS procedures were designed optimize operational efficiency Flightplan, crew, teams a long-term mission with introduced 10 min time delay communication "Mars" Earth. workflow centered on single-file, easy-to-use,...
Abstract Photogrammetry is a low‐cost, nondestructive approach for producing 3‐D models of meteorites the purpose determining sample bulk density. Coupled with use magnetic susceptibility/electrical conductivity field probe, we present measurements interrogation several physical properties, on set Antarctic meteorites. an effective technique over range sizes, meteorite density results that are closely comparable literature values, determined using Archimedean glass bead or laser scanning...
Abstract The field of advanced curation is important for existing astromaterials collections, which includes samples returned by space missions, and meteorites cosmic dust that have been recovered from here on Earth. In order to maximize the scientific return samples, contamination needs be minimized at all stages sample collection, preliminary examination, classification, curation. Utilizing best practice methods, a detailed acquisition plan was implemented during UK's first two expeditions...
With the launch of SEASAT‐1 in June 1978, an altimeter improved performance joined GEOS‐3, which had been operational for three years. The advances design that resulted <10 cm rms height precision are discussed and some early onorbit results presented. In addition to resolution a higher pulse rate, both acted reduce noise, incorporated microcomputer allowed flexibility choice tracker characteristics provided on‐board computation significant waveheight. Under consideration future missions...
NASA's Stardust mission returned from the comet 81P/Wild2 in 2006 and has yielded a plethora of research looking into composition attributes comet. The itself collected thousands cometary dust particles as it flew through coma at relative speed 6.1 km s-1. This work focuses on one most abundant minerals solar system – olivine. Previous shown capture affects this mineral similar impacts to that experienced during mission. However, past looked effects isolated grains which would be rare...
