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 ...
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 pioneering probe made its closest approach to the star on Christmas Eve, zipping past just 3.8 million miles from the solar surface at a speed of about 430,000 miles an hour.
The Parker Solar Probe appears to have successfully completed a journey to within 3.8 million miles of the Sun’s surface as part of its mission to explore the still mysterious processes that ...
The Parker Solar Probe can also be measured as the fastest object, because of its orbital speed relative to the Sun at perihelion: 95.3 km/s (343,000 km/h; 213,000 mph). [c] Because it remains in solar orbit, its specific orbital energy relative to the Sun is lower than New Horizons and other artificial objects escaping the Solar System.

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.
The Parker Solar Probe (via Venus) plans a maximum C 3 of 154 km 2 /s 2. [6] Typical ballistic C 3 (km 2 /s 2) to get from Earth to various planets: Mars 8-16, [7] Jupiter 80, Saturn or Uranus 147. [8] To Pluto (with its orbital inclination) needs about 160–164 km 2 /s 2. [9]
