Parker Solar Probe Breaks Record, Becomes Closest Spacecraft to 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. 29, 2018, at about
1:04 p.m. EDT, as calculated by the Parker Solar Probe team.
The previous record for closest solar approach was set by the German-American Helios 2 spacecraft
in April 1976. As the Parker Solar Probe mission progresses, the
spacecraft will repeatedly break its own records, with a final close
approach of 3.83 million miles from the Sun’s surface expected in 2024.
“It’s been just 78 days since Parker Solar Probe launched, and we’ve
now come closer to our star than any other spacecraft in history,” said
Project Manager Andy Driesman, from the Johns Hopkins Applied Physics
Laboratory in Laurel, Maryland. “It’s a proud moment for the team,
though we remain focused on our first solar encounter, which begins on
Oct. 31.”
Parker Solar Probe is also expected to break the record for fastest
spacecraft traveling relative to the Sun on Oct. 29 at about 10:54 p.m.
EDT. The current record for heliocentric speed is 153,454 miles per
hour, set by Helios 2 in April 1976.
