Voyager 1 crossed the termination shock of the supersonic flow of the solar wind on 16 December 2004 at a distance of 94.01 astronomical units from the Sun, becoming the first spacecraft to begin exploring the heliosheath, the outermost layer of the heliosphere. The shock is a steady source of low-energy protons with an energy spectrum ∼E–1.41 ± 0.15 from 0.5 to ∼3.5 megaelectron volts, consistent with a weak termination shock having a solar wind velocity jump ratio \batchmode \documentclass… Expand

Heliospheric Magnetic Fields and Termination Shock Crossing: Voyager 1
After launch in 1977 and 27 years of continuously studying the He- liospheric Magnetic Field(HMF) from 1 to > 98 AU, the dual magnetometers on the Voyager 1 spacecraft detected a single crossing of… Expand
Challenges to cosmic ray modeling: from beyond the solar wind termination shock
Abstract Voyager 1 crossed the solar wind termination shock on December 16, 2004 at a distance of 94 AU from the Sun, to become the first spacecraft to explore the termination shock region and to… Expand
Zero outward flow velocity for plasma in a heliosheath transition layer
TLDR
It now seems that Voyager 1 has entered a finite transition layer of zero-radial-velocity plasma flow, indicating that the spacecraft may be close to the heliopause, the border between the heliosheath and the interstellar plasma. Expand
SPECTRAL EVOLUTION OF ANOMALOUS COSMIC RAYS AT VOYAGER 1 BEYOND THE TERMINATION SHOCK
When the Voyager 1 spacecraft crossed the termination shock (TS) on 2004 December 16, the energy spectra of anomalous cosmic rays (ACRs) could not have been produced by steady-state diffusive shock… Expand
Cool heliosheath plasma and deceleration of the upstream solar wind at the termination shock
TLDR
The termination shock is a weak, quasi-perpendicular shock that heats the thermal plasma very little and an unexpected finding is that the flow is still supersonic with respect to the thermal ions downstream of the termination shock. Expand
Observations of the Termination Shock and Heliosheath
Voyagers 1 and 2 have both crossed the solar wind termination shock and are now in the heliosheath, the region of shocked solar wind plasma before the heliopause. This paper reviews observations of… Expand
Voyager 1 in the Foreshock, Termination Shock, and Heliosheath
TLDR
Observations from Voyager 1 are interpreted as evidence that V1 was crossed by the TS on 2004/351 (during a tracking gap) at 94.0 astronomical units, evidently as the shock was moving radially inward in response to decreasing solar wind ram pressure, and that V 1 has remained in the heliosheath until at least mid-2005.

Voyager observations in the outer heliosphere and interstellar medium
The Voyager spacecraft are making the first direct plasma measurements of the heliosheath and interstellar medium. This paper discusses the differences in the heliosheath observations of Voyager 1… Expand
Voyager observations of the interaction of the heliosphere with the interstellar medium
TLDR
A brief review and update on the Voyager observations of the interaction of the heliosphere with the interstellar medium and the plasma flow in the Voyagers 1 (V1) and 2 (V2) directions are very different. Expand
The Heliospheric Termination Shock
The heliospheric termination shock is a vast, spheroidal shock wave marking the transition from the supersonic solar wind to the slower flow in the heliosheath, in response to the pressure of the… Expand

Voyager 1 exited the solar wind at a distance of ∼85 au from the Sun
The outer limit of the Solar System is often considered to be at the distance from the Sun where the solar wind changes from supersonic to subsonic flow. Theory predicts that a termination shock… Expand

Enhancements of energetic particles near the heliospheric termination shock
TLDR
A significant increase in the numbers of energetic ions and electrons that persisted for seven months beginning in mid-2002 is reported, arguing that the radial anisotropy of the cosmic rays is expected to be small in the foreshock region, as is observed. Expand
Crossing the Termination Shock into the Heliosheath: Magnetic Fields
TLDR
Magnetic fields measured by Voyager 1 show that the spacecraft crossed or was crossed by the termination shock on about 16 December 2004 at 94.0 astronomical units, and the cosmic ray intensity increased when B was relatively large in the heliosheath. Expand
Composition of Anomalous Cosmic Rays and Other Heliospheric Ions

Cosmic Ray Acceleration and Transport Around the Termination Shock
The recent enhancements of particle fluxes at Voyager‐1 are most likely connected with the closeness of the termination shock (TS). Near the TS, the topology of the magnetic field lines and their… Expand
