NASA’s Solar Probe completes 2nd flyby of Sun
Washington: NASA’s Parker Solar Probe has successfully completed its second close approach to the Sun, the US space agency has said.
The maneuver, called a perihelion, resulted in a closest approach at 6:40 p.m. EDT (2240 GMT) on April 4. The spacecraft
was about 24 million kms above the surface of the Sun.
Parker Solar Probe was travelling at 213,200 miles per hour during this perihelion, and is now entering the outbound phase of its second solar orbit, NASA said in a statement on Friday.
“The spacecraft is performing as designed, and it was great to be able to track it during this entire perihelion,” said Nickalaus Pinkine, Parker Solar Probe mission operations manager at Johns Hopkins Applied Physics Laboratory, or APL, in Maryland.
“We’re looking forward to getting the science data down from this encounter in the coming weeks so the science teams can continue to explore the mysteries of the corona and the Sun,” Pinkine added.
Launched on August 12, 2018, the Parker Solar Probe, NASA’s historic small car-sized probe, will journey steadily closer to the Sun until it makes its closest approach at 3.8 million miles.
Throughout its mission, the probe will make six more Venus gravity assists and 24 total passes by the Sun.
The spacecraft in January completed its first orbit of the Sun, reaching the point in its orbit farthest from our star, called aphelion.
For the second perihelion, the Probe began the solar encounter on March 30, and it will conclude on April 10.
The solar encounter phase is roughly defined as when the spacecraft is within 0.25 AU – or 23,250,000 miles – of the Sun.
One AU, or astronomical unit, is about 93 million miles, the average distance from the Sun to Earth, NASA said.
