Placing the warmth to Helios — Science Information, July 6, 1974
Helios, an area probe scheduled to move nearer to the solar than another artifical object ever introduced, has effectively survived a flooring take a look at that revealed it to temperatures believed to be as prime as any it is going to face right through its challenge…. All the way through the take a look at, portions of the spacecraft reached — and survived — temperatures as much as 700 levels F. Helios, to be introduced in [December], will cross inside of 28 million miles of the solar.

The Helios challenge’s find out about of the solar equipped key insights into the sun wind, the solar’s magnetic box, galactic rays and extra (SN: 12/21/74). Its good fortune helped pave the way in which for NASA’s Parker Sun Probe, which has been looking at our megastar’s outer environment, or corona, since 2018. Parker has dipped inside of 5 million miles of the solar’s floor and can ultimately swing inside of 4 million miles. Such encounters have pinpointed a layer that separates the corona from interstellar house and located proof that snappy magnetic box traces might boost up the sun wind (SN: 12/15/21; SN: 06/09/23). The probe will subsequent stumble upon the solar in September.
