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 was launched Aug. 12, 2018 with the mission of coming within 4 million miles of the sun's surface to study the formation of the solar wind.
Solar maximum is the regular period of greatest solar activity during the Sun's 11-year solar cycle. During solar maximum, large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%. [2] On average, the solar cycle takes about 11 years to go from one solar maximum to the next, with duration observed varying from 9 to ...
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 ...
The Sun has reached a period of peak activity in an 11-year cycle known as the Solar Maximum, marked by recent geomagnetic storms and near-global aurora light displays.
To keep the solar panels at a temperature below 165 °C (329 °F) when in proximity to the Sun, the solar cells are interspersed with mirrors, covering 50% of the surface and reflecting part of the incident sunlight while dissipating the excess heat. The power supplied by the solar panels is a minimum of 240 watts when the probe is at aphelion.
The date of the next solar maximum will not be known until it has already passed, with space weather forecasters currently predicting that it will take place at some point between now and early 2026.
Solar cycle 24 is the most recently completed solar cycle, the 24th since 1755, when extensive recording of solar sunspot activity began. [ 1 ] [ 2 ] It began in December 2008 with a minimum smoothed sunspot number of 2.2, [ 3 ] [ failed verification ] and ended in December 2019. [ 4 ]
