Deep Space 2: The Mars Microprobe Mission

The Mars Microprobe Mission will be the second of the New Millennium Program's technology development missions to planetary bodies. The mission consists of two penetrators that weigh 2.4 kg each and are being carried as a piggy back payload on the Mars Polar Lander cruise ring.

Io and the Early Earth

The youngest surface in the solar systems may be giving us clues about the earliest volcanics on Earth.

Mid-Infrared Spectra of Comets P/Borrelly, P/Faye, and P/Schaumasse

A 10 micrometer silicate emission feature has been discovered in the spectra of comets P/Borrelly and P/Faye at R of roughly 1.5 AU although this feature was not observed in P/Schaumasse. A model is presented to show how the shape of the silicate feature can depend on the way in which silicate and absorbing material are mixed in the grains.

Volcanic Eruptions on Io: Heat Flow, Resurfacing, and Lava Composition

In this paper we consider the infrared outbursts on Io reported over the last 15 years and examine the implications for resurfacing rates and heat flow using a recent, well observed, eruption sequence. A large change was observed in Io's infrared emission on January 9, 1990 at several different wavelengths. We model this event as due to a large actively erupting lava flow. The flow increased its area at a rate of 1.5 x 10 5 m 2 s -1 and cooled from 1225 K to 555 K over about 2.6 hours. This event is consistent with other Io infrared outbursts and is used in this paper to estimate the more general characteristics of Ionian volcanism, resurfacing, and heat flow. The inferred eruption rate of 3 x 10 5 m 3 s -1 is very high, but is not unprecedented on the Earth.

Io's Heat Flow From Infrared Radiometry: 1983-1993

This paper presents results from a decade of infrared radiometry of IO. Results indicated that a new thermophysical model is required to match all the data. The thermal anomalies are modeled with a total of 10 source components at five locations.
