A detailed overview of the knowledge gaps in our understanding of the heliospheric
interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided …

Velocity and direction of the flow of the interstellar helium and its temperature and density
have been determined from the measurements of the ULYSSES/GAS experiment for two …

Using an absorption cell, we measured the Doppler shifts of the interstellar hydrogen
resonance glow to show the direction of the neutral hydrogen flow as it enters the inner …

The Earth's hydrogen exosphere Lyman‐α radiation was mapped with the Solar Wind
Anisotropies/Solar and Heliospheric Observatory (SWAN/SOHO) instrument in January …

The dual spacecraft mission BepiColombo is the first joint mission between the European
Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA) to explore …

Mars has lost a large fraction of its water to space, with the H component of this loss thought
to occur mainly as a result of thermal (Jeans) escape from the upper atmosphere …

T wo W ide-angle I maging N eutral-atom S pectrometers (TWINS) is a NASA Explorer
Mission-of-Opportunity to stereoscopically image the Earth's magnetosphere for the first …

This review addresses our current understanding of comets that venture close to the Sun,
and are hence exposed to much more extreme conditions than comets that are typically …

The solar wind (SW) is an outflow of the solar coronal plasma, which expands
supersonically throughout the heliosphere. SW particles interact by charge exchange with …

Recently Lallement et al.(2005, Science, 307, 1447) reported that the direction of the flow of
interstellar neutral hydrogen in the heliosphere is deflected by~ 4° from the direction of the …
