NASA's Parker Solar Probe is about to make its closest approach to the sun. The spacecraft will fly within 3.8 million miles of the solar surface. The spacecraft is collecting essential data that ...
The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [6] is a NASA space probe launched in 2018 to make observations of the Sun's outer corona. It used repeated gravity assists from Venus to develop an eccentric orbit, approaching within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ] [ 8 ] from ...
English: NASA’s Parker Solar Probe mission launched Aug. 11 from Cape Canaveral Air Force Station in Florida. The mission will be the first to fly directly through the Sun’s corona – the hazardous region of intense heat and solar radiation in the Sun’s atmosphere that is visible during an eclipse.
English: Parker Solar Probe has now “touched the Sun”, passing through the Sun’s outer atmosphere, the corona for the first time in April 2021. The boundary that marks the edge of the corona is the Alfvén critical surface.
IS☉IS hardware being prepared for its mission, EPI-Lo hardware shown in 2017. Integrated Science Investigation of the Sun or IS☉IS, is an instrument aboard the Parker Solar Probe, a space probe designed to study the Sun. IS☉IS is focused on measuring energetic particles from the Sun, including electrons, protons, and ions. [1]
SWEAP consists of the Solar Probe Cup (SPC), a Faraday cup that faces the Sun and is designed to measure mostly protons and alphas with the occasional measurement of electrons in the space environment near the Sun: the Solar Probe Analyzers (SPAN-A and SPAN-B); [10] [11] and the SWEAP electronics module (SWEM).
For example, though Voyager 1 is still contactable en-route to the Oort Cloud and has exited the Solar System, it is listed as "mission complete" because its primary task of studying Jupiter and Saturn has been accomplished. Once a probe has reached its first primary target, it is no longer listed as "en route" whether or not further travel is ...
Magnetic (or solar) switchback is a rapid polarity reversals of the radial heliospheric magnetic field. [4] These events have been termed "switchbacks", when referring to the change in magnetic field direction, or "velocity spikes", when referring to the sharp increase in solar wind speed. [3] The switchbacks generate heat that warms solar ...
