Deep Space 1 (DS1) is the first interplanetary spacecraft (s/c) using ion propulsion and aims at investigating the compatibility of innovative technology with scientific measurements. DS1 performed a successful flyby at the asteroid Braille on July 29th, 1999. This closest‐ever encounter allowed for the first time a direct measurement of an asteroidal magnetic field. The manifold magnetic disturbances caused by the ion propulsion onboard DS1, however, required an elaborate data processing… 

NEAR Magnetic Field Observations at 433 Eros: First Measurements from the Surface of an Asteroid

Abstract The magnetometer investigation aboard the NEAR-Shoemaker spacecraft has obtained extensive magnetic field observations throughout the 433 Eros environment, from distances in excess of

RPC-MAG The Fluxgate Magnetometer in the ROSETTA Plasma Consortium

The fluxgate magnetometer experiment onboard the ROSETTA spacecraft aims to measure the magnetic field in the interaction region of the solar wind plasma with comet 67P/Churyumov-Gerasimenko. It

Dust impacts at Comet P/Borrelly

The NASA DS1 spacecraft flew past comet P/Borrelly on September 22, 2001, on the sunward side of the comet. Dust impacts were detected by sharp increases (or decreases) in electric fields measured by

The MASCOT Magnetometer

The Mobile Asteroid Scout (MASCOT) is a small lander on board the Hayabusa2 mission of the Japan Aerospace Exploration Agency to the asteroid 162173 Ryugu. Among the instruments on MASCOT is a

Magnetic Properties of Asteroid (162173) Ryugu

Observations of the magnetization state of asteroids indicate diverse properties. Values between 1.9 × 10 −6 Am 2 /kg (Eros) and 10 −2 Am 2 /kg (Braille) have been reported. A more detailed

443 Eros: Problems with the meteorite magnetism record in attempting an asteroid match

Abstract— The magnetometer experiment (MAG) onboard the Near‐Earth Asteroid Rendezvous (NEAR)‐Shoemaker spacecraft detected no global scale magnetization and established a maximum magnetization of

Magnetic Field Signatures Near Galileo's Closest Approach to Gaspra

Two large magnetic field rotations were recorded by the spacecraft Galileo 1 minute before and 2 minutes after its closest approach to the asteroid Gaspra, and the location of the magnetic signatures suggests that perturbations are carried by waves in the magnetosonic-whistler mode with wavelengths between electron and ion gyro radii.

Deep Space One Investigations of Ion Propulsion Contamination: Overview and Initial Results

NASA’s New Millennium Deep Space One (DS1) is the first interplanetary spacecraft operated on solar electric propulsion. The DS1 spacecraft was launched on October 24, 1998. Using a 30cm diameter

A Magnetohydrodynamic Model of Solar Wind Interaction with Asteroid Gaspra

The solar wind response to a small-sized magnetized body is modeled on the basis of a two-dimensional magnetohydrodynamic (MHD) plasma description including Hall current corrections (Hall-MHD model).

Solar wind response to a magnetized asteroid: Linear theory

Abstract We study the interaction between a small, magnetized asteroid and the solar wind (SW) in the “submagnetospheric” regime, in which the asteroid's magnetic field is too small to establish

Introduction To Multivariate Analysis

Dr Dunteman clarifies advanced concepts for both students and researchers in an intuitive, non-rigorous manner, and every technique is illustrated (step-by-step) on small, hypothetical, yet meaningful social science data bases.
