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 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.
On Sept. 27, 2023, the probe set dual records: making the closest approach of any vehicle to the sun, coming within 4.5 million miles of it; and reaching the fastest speed of any spacecraft ...
The period of performance is 76 months. SWFO-L1 will provide NOAA with the continuity of solar wind data and coronal mass ejection imagery, the National Weather Service's highest priority for space weather observations. University of California, Berkeley was awarded US$7.5 million for the development of the Supra-Thermal Ion Sensor (STIS). [7]
NASA says the sun is in the highly active "maximum phase" of its 11-year solar cycle.. That means there will probably be big solar storms bringing beautiful aurora in the next year or so. Solar ...
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 CME is expected to cause a moderate solar storm here on Earth on Thursday and Friday, according to NOAA. ... soon come to a peak as the sun reaches its solar maximum stage in the coming ...
Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [2] It is expected to continue until about 2030. [3] [4]
