[7] [9] It is the fastest object ever built on Earth. [10] The project was announced in the fiscal 2009 budget year. Johns Hopkins University Applied Physics Laboratory designed and built the spacecraft, [11] which was launched on 12 August 2018. [2]
It flew past the Kuiper belt object 486958 Arrokoth on January 1, 2019, as part of the Kuiper Belt Extended Mission (KEM). [10] On April 17, 2021, it reached a distance of 50 AU from the Sun. [ 11 ] Although other probes were launched first, Voyager 1 has achieved a higher speed and overtaken all others.

Atmospheric entry speed of the Galileo atmospheric probe—Fastest controlled atmospheric entry for a human-made object. 66,000: 240,000: 150,000 0.00022: Lower speed bound of the steel plate cap from the Pascal-B nuclear test of Operation Plumbbob. [26] [circular reference] 70,220: 252,800: 157,100 0.00023: Speed of the Helios 2 solar probe ...
The Parker Solar Probe can also be measured as the fastest object, because of its orbital speed relative to the Sun at perihelion: 95.3 km/s (343,000 km/h; 213,000 mph). [c] Because it remains in solar orbit, its specific orbital energy relative to the Sun is lower than New Horizons and other artificial objects escaping the Solar System.
The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
The Apollo 10 crew (Thomas Stafford, John W. Young and Eugene Cernan) achieved the highest speed relative to Earth ever attained by humans: 39,897 kilometers per hour (11,082 meters per second or 24,791 miles per hour, about 32 times the speed of sound and 0.0037% of the speed of light). [14] The record was set 26 May 1969. [14]
