Single Point Gradiometer for Planetary Applications

We have designed and fabricated a microelectromechanical device, based on the alternating field gradient concept, to measure surface magnetic field gradient on planets. Its sensitivity is 4 10-4 T/m, which is appropriate for magnetite outcrops and areas with rocks formed at different stages recording geomagnetic field reversals. We present the results obtained with three different prototypes.

Planetary exploration in the time of astrobiology: Protecting against biological contamination

These are intriguing times in the exploration of other solar-system bodies. Continuing discoveries about life on Earth and the return of data suggesting the presence of liquid water environments on or under the surfaces of other planets and moons have combined to suggest the significant possibility that extraterrestrial life may exist in this solar system. Similarly, not since the Viking missions of the mid-1970s has there been as great an appreciation for the potential for Earth life to contaminate other worlds. Current plans for the exploration of the solar system include constraints intended to prevent biological contamination from being spread by solar-system exploration missions.

Kosciuszko, leader and exile,

"The second and the last part of a biography of Kosciuszko, the first part of which has been published under the title 'Kosciuszko in the American revolution' by the Polish institute of arts and sciences in America, in 1943 ... Intended to mark and to honor the bicentennial of Kosciuszko's birth in 1746."--Pref.
