We seek to understand the quantitative role of the dominant physical processes (charge-exchange, adiabatic heating, stochastic acceleration) governing the proton distribution in the heliotail using observations of hydrogen energetic neutral atoms (ENAs) from the Interstellar Boundary Explorer (IBEX).

In a press release issued on June 1, 2018, NASA announced the selection of a proposal team lead by Professor David J. McComas at Princeton University to lead the upcoming Interstellar Mapping and Acceleration Probe (IMAP) mission. IMAP is a part of NASA's Solar Terrestrial Probes (STP) Program in NASA's Science Mission Directorate Heliophysics...

In late 2014, the solar wind dynamic pressure increased by ~50% over a relatively short time (~6 months). In early 2017, the Interstellar Boundary Explorer (IBEX) observed an increase in heliospheric energetic neutral atom (ENA) fluxes from directions near the front of the heliosphere.

Our heliosphere—the bubble in the local interstellar medium produced by the Sun’s outflowing solar wind—has finally responded to a large increase in solar wind output and pressure in the second half of 2014.

The Parker Solar Probe, a planned NASA robotic spacecraft to probe the outer corona of the Sun, has been scheduled for a July 31, 2018 launch at Cape Canaveral.  The probe will approach to within 8.86 solar radii (3.85 million miles) from the 'surface' (photosphere) of the Sun.
