NASA’s Voyager probes are failing, creating an urgent need for a new deep-space mission. A proposed interstellar probe could ...

The heliosphere, a cosmic bubble formed by the Sun, protects our solar system from interstellar threats and influences life's ...

Radioisotope thermoelectric generators do not rely on chemical reactions like the batteries in your phone. Instead, they rely ...

Over the decades, after the planetary portion of the mission concluded, several instruments were deactivated, leaving the ones needed to investigate the heliosphere – the bubble of charged particles ...

PUNCH, or Polarimeter to Unify the Corona and Heliosphere, will study how the sun affects the solar system. The mission will observe the sun’s hot outer atmosphere, called the corona ...

NASA and SpaceX late Monday said they were standing down the launch of the SPHEREx and PUNCH spacecraft missions due to unfavorable weather at the launch site and an issue with one of the spacecrafts.

the region outside the heliosphere. Voyager 1 crossed the edge of the heliosphere and the beginning of interstellar space in 2012, while Voyager 2 did so in 2018. No previous human-made spacecraft has ...

NASA powers down Voyager probes to save power. Instruments shut off to extend life, as the trailblazing spacecraft push the limits of exploration in deep space.

The fact that the Voyager spacecraft are the only two human-made objects to make it to interstellar space means that the data they collect is unique. Thus, the decision to switch off any ...

If we don't turn off an instrument on each Voyager now, they would probably have only a few more months of power before we would need to declare end of mission." Considering no other human-made object ...

The wall of fire. At one point in time, both probes went past the heliosphere. That is where solar winds emitted from our sun still blow things outwards. But what Voyager 2, backed up by data from ...

This data was essential to knowing when Voyager 1 exited the heliosphere—thus achieving one of many historic firsts—back in 2012. NASA turned off the cosmic ray subsystem on Feb. 25 ...
