NASA’s Parker Solar Probe began its fourth solar encounter today at 9:00 am EST, at a distance of about 23.3 million miles from the Sun’s surface. It will reach perihelion, its closest distance to our star, during this orbit on Jan.
There’s a wind that emanates from the Sun, and it blows not like a soft whistle, but like a hurricane’s scream. Made of electrons, protons and heavier ions, the solar wind courses through the solar system at roughly 1 million mph (1.6 million kph), barreling over everything in its path.
The Parker Solar Probe mission has named Helene Winters of the Johns Hopkins Applied Physics Laboratory as project manager, effective January 6, 2020. Winters assumes this role from Patrick Hill of APL, who has moved into a new leadership position in the Laboratory’s Civil Space Mission Area.
On Dec. 26, Parker Solar Probe successfully completed its second flyby of Venus. The spacecraft used Venus to slow itself down, approaching the planet at a distance of about 1,870 miles from Venus's surface during the second gravity assist of the mission.
After nearly 17 months in space culminating with the release of new science data, Parker Solar Probe is right on course for its second Venus gravity assist maneuver. This flyby will set the spacecraft up for its fourth perihelion of the Sun, during which it will set records for spacecraft speed and closest solar distance, while continuing to gather groundbreaking data from within the Sun's corona to help scientists make new discoveries. On Dec.
Nearly a year and a half into its mission, Parker Solar Probe has returned gigabytes of data on the Sun and its atmosphere. Following the release of the very first science from the mission, five researchers presented additional new findings from Parker Solar Probe at the fall meeting of the American Geophysical Union on Dec.

Weeks after Parker Solar Probe made the closest-ever approach to a star, the science data from the first solar encounter is just making its way into the hands of the mission's scientists.
NASA’s Parker Solar Probe – humanity’s first mission to “touch” the Sun – was today named the innovation of the year by Popular Science. The revolutionary spacecraft – designed, built, and operated for NASA by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland – launched on August 12, 2018.
On Nov. 16, Parker Solar Probe reported that all systems are operating well in the first detailed performance and health update sent to Earth by the spacecraft since its first solar encounter.
Parker Solar Probe is alive and well after skimming by the Sun at just 15 million miles from our star's surface. This is far closer than any spacecraft has ever gone — the previous record was set by Helios B in 1976 and broken by Parker on Oct.
At about 10:28 p.m. EST on Nov. 5, Parker Solar Probe will achieve its first perihelion - its first close approach to the Sun - and will come within 15 million miles of the Sun's surface.
On Oct. 31, 2018, Parker Solar Probe began its first of 24 solar encounters. This period — which lasts until Nov. 11 — is the time during which the spacecraft is within 0.25 astronomical units, or 23.2 million miles, of the Sun's center.
At about 10:54 p.m. EDT on Oct. 29, Parker Solar Probe surpassed 153,454 miles per hour — as calculated by the mission team — making it the fastest-ever human-made object relative to the Sun.

Two days after NASA’s Parker Solar Probe flew past Venus toward its rendezvous with the Sun, the spacecraft had drawn close enough to our star that its power-generating solar array wings began to tilt themselves inward – a task directed by the spacecraft itself, based on the rising temperatures – away from the Sun and behind the sun shield.
On Oct. 3, 2018, Parker Solar Probe performed the first significant celestial maneuver of its seven-year mission. As the orbits of the spacecraft and Venus converged toward the same point, Parker Solar Probe slipped in front of the planet, allowing Venus' gravity — relatively small by celestial standards — to twist its path and change its speed.
On Oct. 3, Parker Solar Probe successfully completed its flyby of Venus at a distance of about 1,500 miles during the first Venus gravity assist of the mission. These gravity assists will help the spacecraft tighten its orbit closer and closer to the Sun over the course of the mission.Detailed data from the flyby will be assessed over the next few days.
We like to call Parker Solar Probe the coolest, hottest, fastest mission under the Sun — and fall 2018 will prove why. Here are a few mission milestones to look forward to over the coming months.
