We have added the BeppoSAX Gamma-Ray Burst Monitor to the 3rd Interplanetary Network of burst detectors. We analyze 16 bursts whose positions are known to good accuracy from measurements at other wavelengths. We show that there is excellent agreement between the Ulysses/BeppoSAX triangulation annuli and the known positions of these events, and that these annuli can in many cases provide useful ...

The COMPTEL instrument onboard the Compton Gamma{Ray Observatory imaged the bright gamma{ray burst GRB 940301 within 1.6 hours of the event, with a mean 1 error radius of 1.5. The error region was subsequently reened by combining the COMPTEL location with the arc derived from diierences in the event arrival time at the Ulysses and BATSE detectors. Westerbork observations of the COMPTEL error re...

"As [Chris] Scaturro has suggested for years, the name Ulysses S. Grant indeed belongs in Pantheon with other greatest of American heroes. What had been written his so long is a historical disgrace and sad commentary that bygone community. His 'reputational renaissance' overdue, this piece literature just one more recent convincing development will allow to earn do."

We present the mass distribution of interstellar grains measured in situ by the Galileo and Ulysses spaceprobes as cumulative flux. The derived in situ mass distribution per logarithmic size interval is compared to the distribution determined by fitting extinction measurements. Large grains measured in situ contribute significantly to the overall mass of dust in the local interstellar cloud. Th...

"Throughout much of his adult life, disappointment and hardship were Grant’s constant companions. Yet rather than let these circumstances defeat him, Grant endured hardships, learned valuable life lessons from them and, combined with formative background, used to advantage become the greatest most successful battle commander in American military history. So argues Jack Hurst compelling highly e...

[1] It took the solar polar passage of Ulysses in the early 1990s to establish the global structure of the solar wind speed during solar minimum. However, it remains unclear if the solar wind is composed of two distinct populations of solar wind from different sources (e.g., closed loops which open up to produce the slow solar wind) or if the fast and slow solar wind rely on the superradial exp...

Identification by the Ulysses spacecraft of interstellar grains inside the planetary system provides a new window for the study of diffuse interstellar matter. Dust particles observed by Ulysses and confirmed by Galileo are more massive (≥ 10−13 g) than the ’classical’ interstellar grains. Even bigger grains (≈ 10−7 g) were observed in form of interstellar meteors. We analyze the consequences o...

We present a two-stage system for information exploration and retrieval. The first stage, named GALOIS, organizes the information contained into a database into a particular lattice structure; the second stage, named ULYSSES, is a visual interface to access the structure built in the earlier stage. In this paper we focus on the latter. ULYSSES is based on a tight integration of traditional and ...

Radio tracking data acquired from the Ulysses spacecraft during its flight to Jupiter were used to test experimental navigational techniques for processing highly accurate (1 to 2 m) two-way ranging data. While ranging data with this level of accuracy have been routinely used for navigation of Earth-orbiting spacecraft, ranging data from interplanetary spacecraft have in the past been artificia...

We report on observations of energetic particles (EP) during the ascent of ULYSSES to the south pole, on the fast pass from south to north and in the first few months after the north polar pass. After it left the ecliptic plane the spacecraft moved periodically into a corotating (26 days period) fast solar wind stream and observed the accelerated EP associated with the forward and reverse shock...
