Solar Wind Forecasting for Long-term Variations of the Global Heliosphere

open access: yesThe Astrophysical Journal
The large-scale dynamics of the heliosphere is driven by solar activity and variable solar wind (SW) conditions. In situ SW observations inform time-dependent heliosphere modeling efforts but are only available up until the present day, thus restricting ...

Potential effects of optical solar sail degredation on trajectory design [PDF]

open access: yes, 2005
The optical properties of the thin metalized polymer films that are projected for solar sails are assumed to be affected by the erosive effects of the space environment.

Energetic Neutral Atom Fluxes from the Voyager 1 and 2 Directions

open access: yesThe Astrophysical Journal
IBEX observes a globally distributed energetic neutral atom (ENA) flux from the heliosheath and very local interstellar medium (VLISM). Over a 14 yr period, Voyager 1 and Voyager 2 traversed the heliosheath from the termination shock to the heliopause ...

The Heliopause Electrostatic Rapid Transit System (HERTS) Design, Trades, and Analyses Performed in a Two Year NASA Investigation of Electric Sail Propulsion Systems [PDF]

open access: yes, 2017
The Heliopause Electrostatic Rapid Transit System (HERTS) was one of the seven total Phase II NASA Innovative Advanced Concepts (NIAC) that was down-selected in 2015 for continued funding and research.

Inferring the Interstellar Magnetic Field Direction from Energetic Neutral Atom Observations of the Heliotail

open access: yesThe Astrophysical Journal Letters
Determining the magnitude and direction of the interstellar magnetic field ( B _ISM ) is a long-standing problem. To date, some methods to infer the direction and magnitude have utilized best-fit models to the positions of the termination shock and ...

The Passage of the Solar System through the Edge of the Local Bubble

open access: yesThe Astrophysical Journal
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr ^−1 , making the conditions outside the solar system vary with time over millions of years.

Solar Sail Trajectories for Solar Polar and Heliopause Missions [PDF]

open access: yes, 2000
Over the last several years, interest in a more vigorous space exploration program has renewed interest in the use of solar sails for the more demanding space missions.

Signatures of Reconnection and a Split Heliospheric Tail in High-energy Energetic Neutral Atoms

open access: yesThe Astrophysical Journal
The shape of the heliosphere, regarded as comet-like since the 1960s, has recently been the subject of intense debate in the last decade. There is disagreement as to whether the heliospheric tail extends to ∼10,000 au in a comet-like shape or if it is ...
