Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, Parker Solar Probe hurtled through the solar atmosphere at 430,000 miles per hour - faster than any human-made object has ever moved. A beacon tone, received in the mission operations center at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, late in the evening of Thursday, Dec. 26, confirmed the spacecraft had made it through the encounter safely.
The telemetry (or housekeeping data) that APL began receiving on Jan. 1 provided more detail on the spacecraft's operating status and condition. It showed, for example, that Parker had executed the commands that had been programmed into its flight computers before the flyby, and that its science instruments were operational during the flyby itself.
Telemetry transmission, through NASA's Deep Space Network, continues through Thursday. Science data transmission will begin later this month, when the spacecraft and its most powerful onboard antenna are in better alignment with Earth to transmit at higher data rates. Parker Solar Probe's next two close passes of the Sun, at approximately the same distance and speed, will occur March 22 and June 19.
