At just before 1:50 pm EDT on Sept. 1, 2019, NASA’s Parker Solar Probe completed its third close approach (or perihelion) of the Sun. At the time of perihelion, the spacecraft was about 15 million miles from the Sun’s surface, traveling at more than 213,200 miles per hour.
After Parker Solar Probe’s successful first year in space, the mission team has decided to extend science observations as the spacecraft approaches its third solar encounter. Parker Solar Probe turned on its four instrument suites on Aug.
Since NASA's Parker Solar Probe launched on Aug. 12, 2018, Earth has made a single trip around the Sun — while the daring solar explorer is well into its third orbit around our star.
As NASA’s Parker Solar Probe approaches its third encounter with the Sun, mission scientists are hard at work poring over data from the spacecraft's first two flybys of our star — and thanks to excellent performance by the spacecraft and the mission operations team, they're about to get something extra.
It’s one of the greatest and longest-running mysteries surrounding, quite literally, our sun—why is its outer atmosphere hotter than its fiery surface? University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA’s Parker Solar Probe.
Parker Solar Probe has successfully completed its second close approach to the Sun, called perihelion, and is now entering the outbound phase of its second solar orbit. At 6:40 p.m.
Patrick Hill of the Johns Hopkins Applied Physics Laboratory (APL) has been named the Parker Solar Probe project manager effective April 1, 2019. In this new role, he will be responsible for overall mission success and execution, including the collection and analysis of science data, sustained flight spacecraft engineering, and mission operations.
On March 30, 2019, Parker Solar Probe begins the second solar encounter phase of its mission, culminating in its closest approach to the Sun, called perihelion, on April 4. During this solar encounter phase, which lasts until April 10, the spacecraft's four suites of science instruments are fully operational and storing science data collected from within the Sun's corona.
The Parker Solar Probe team has been named the winner of the 2018 Neil Armstrong Space Flight Achievement Award, given by the American Astronautical Society at its 57th Robert H. Goddard Memorial Symposium in Silver Spring, Maryland.
On Jan. 19, 2019, just 161 days after its launch from Cape Canaveral Air Force Station in Florida, NASA’s Parker Solar Probe completed its first orbit of the Sun, reaching the point in its orbit farthest from our star, called aphelion.
As NASA’s Parker Solar Probe begins the second of 24 planned orbits—on track for its second perihelion, or closest approach to the Sun, on April 4, 2019—take a look back to how the spacecraft was built at the Johns Hopkins Applied Physics Laboratory in Maryland.
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.
Parker Solar Probe now holds the record for closest approach to the Sun by a human-made object. The spacecraft passed the current record of 26.55 million miles from the Sun's surface on Oct.
On Sept. 25, 2018, Parker Solar Probe captured a view of Earth as it sped toward the first Venus gravity assist of the mission. Earth is the bright, round object visible in the right side of the image.
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.
As Parker Solar Probe – named for pioneering solar scientist Eugene Parker – rose from Launch Complex 37 at Cape Canaveral Air Force Station into the skies above Florida in the early morning hours of Aug.
Just over a month into its mission, Parker Solar Probe has returned first-light data from each of its four instrument suites. These early observations – while not yet examples of the key science observations Parker Solar Probe will take closer to the Sun – show that each of the instruments is working well.
On Sept. 13, Parker Solar Probe's first-of-its-kind water-cooled Solar Array Cooling System (or SACS) was made fully operational. The SACS will protect Parker Solar Probe’s solar arrays — responsible for powering the spacecraft — from the intense heat of the Sun.
