Topic: Heliopause
Each of these Heliophysics Science Mission of Opportunity proposals will receive $400,000 to conduct a nine-month mission concept study. ![]() NASA has chosen two new science proposals for nine-month concept studies to advance our understanding of how the particles and energy in space – shown here flowing from the Sun in an illustration of the solar wind – affect the fundamental nature of space. One proposal will ultimately be chosen to launch along with NASA’s upcoming Interstellar Mapping and Acceleration Probe in October 2024.

NASA’s Voyager 2 probe maybe about to enter Interstellar SpaceNASA’s Jet Propulsion Laboratory
Since 2007 the probe has been traveling through the outermost layer of the heliosphere — the vast bubble around the Sun and the planets dominated by solar material and magnetic fields. Voyager scientists have been watching for the spacecraft to reach the outer boundary of the heliosphere, known as the heliopause. Once Voyager 2 exits the heliosphere, it will become the second human-made object, after Voyager 1, to enter interstellar space. ![]() This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere.

NASA’s Journey to Mars builds ground work for missions beyond our Solar SystemNASA Headquarters
Closer to home, we’re working on techniques to help us cross greater distances. Astronauts feast on romaine lettuce grown aboard the International Space Station, perhaps a preview of future banquets en route to Mars, or to deep space. ![]() A selfie taken by Curiosity the Mars rover in the Murray Buttes area. NASA’s Journey to Mars, a plan aimed at building on robotic missions to send humans to the red planet, could be helping lay the groundwork.

NASA tests E-Sail Tech that would use Solar Wind to propel a SpacecraftWritten by Tracy McMahan and Kimberly Newton
The test results will provide modeling data for the Heliopause Electrostatic Rapid Transit System (HERTS). The proposed HERTS E-Sail concept, a propellant-less propulsion system, would harness solar wind to travel into interstellar space. ![]() In this concept, long, very thin, bare wires construct the large, circular E-Sail that would electrostatically repel the fast moving solar protons. The momentum exchange produced as the protons are repelled by the positively charged wires would create the spacecraft’s thrust.
