NASA solar probe begins second orbit of Sun


NASA solar probe begins second orbit of Sun

NASA's Parker Solar Probe has begun its second orbit of the Sun and is on track for its closest approach to our star, the US space agency said. Just 161 days after its launch, the Praker probe completed its first orbit of the Sun on January 19.

The spacecraft has now begun the second of 24 planned orbits, on track for its second perihelion, or closest approach to the Sun, on April 4. Parker Solar Probe entered full operational status on January 1, with all systems online and operating as designed. The spacecraft has been delivering data from its instruments to Earth via the Deep Space Network, and to date more than 17 gigabits of science data has been downloaded.

The full dataset from the first orbit will be downloaded by April. "It's been an illuminating and fascinating first orbit," said Andy Driesman, of the Johns Hopkins University Applied Physics Laboratory, which manages the mission for NASA.

"We've learned a lot about how the spacecraft operates and reacts to the solar environment, and I'm proud to say the team's projections have been very accurate," said Driesman, who is the Parker Solar Probe Project Manager. "We've always said that we don't know what to expect until we look at the data," said Project Scientist Nour Raouafi, also of APL.

"The data we have received hints at many new things that we've not seen before and at potential new discoveries. Parker Solar Probe is delivering on the mission's promise of revealing the mysteries of our Sun," said Raouafi. In preparation for the next encounter in April, the spacecraft's solid state recorder is being emptied of files that have already been delivered to Earth.

In addition, the spacecraft is receiving updated positional and navigation information and is being loaded with a new automated command sequence, which contains about one month's worth of instructions. The closest approach in April will bring the spacecraft to a distance of about 15 million miles from the Sun -- just over half the previous close solar approach record of about 27 million miles set by Helios 2 in 1976.

The spacecraft's four instrument suites will help scientists begin to answer outstanding questions about the Sun's fundamental physics -- including how particles and solar material are accelerated out into space at such high speeds and why the Sun's atmosphere, the corona, is so much hotter than the surface below.
