According to NASA, the spacecraft is well on its way. The space agency reports that the probe now holds the record for closest approach to the Sun by a human-made object, passing inside the current record of 42.7 million kilometers from the Sun’s surface on Oct. 29, 2018, at about 1:04pm ET (17:04 UTC).
