what is the fastest speeds we've achieved in space?

Question

manned and unmanned and monkeyed i guess

Answer 1

The New Horizons probe launched on 19 January 2006 due to arrive at and flyby Pluto and Charon in July 2015 following a gravity assist from Jupiter next month claims to have had the fastest-ever launch speed:

The New Horizons spacecraft was launched directly into an Earth- and solar-escape trajectory. It had an Earth-relative velocity of about 16.21 km/s (36,300 mph) just after its last engine shut down, making it the fastest spacecraft launch ever.

New Horizons is the first mission in NASA's New Frontiers mission category, larger and more expensive than Discovery missions but smaller than "flagship" programs.

New Horizons is now proceeding to a Jupiter gravity assist in February 2007. It will pass through the Jupiter system at 21 km/s (47,000 mph), with closest approach to Jupiter occurring at approximately 06:00 UTC February 28, 2007.

New Horizons was the first probe launched directly towards Jupiter since the Ulysses probe in 1990. Although there were backup launch opportunities in February 2006 and February 2007, only the first 23 days of the 2006 window permitted the Jupiter flyby. Any launch outside that period would have forced the spacecraft to fly a slower trajectory directly to Pluto, delaying its encounter by 2–4 years.

The flyby will increase New Horizons' speed away from the Sun by nearly 4 km/s (9,000 mph), putting the spacecraft on a faster trajectory to Pluto, about 2.5 degrees out of the plane of the solar system (the "ecliptic").

The New Horizons probe closest approach to Jupiter will be February 28, 2007. While at Jupiter, New Horizon's instruments will refine the orbits of Jupiter's inner moons, particularly Amalthea. The probe's cameras will measure volcanoes on Io and study all 4 Gallilean moons in detail. Imaging of the Jovian system began September 4, 2006

Previous rockets to Jupiter took 2 years to arrive. Yet this one was close enough to study the larger moons after a mere 7.5 months.

Answer 2

the fastest man has ever gone was during Apollo 14 1971 during reentry the spacecraft accelerated to a supersonic speed of 14,000 miles per hour or mach 17.5

Answer 3

expensive sir: I enjoyed your final sentence interior the question the terrific. That replace into the place you reported "theoretically of direction." There are actually not any recent, sensible or theoretical skill of increasing guy made contraptions lots speedier than approximately 50,000 Miles consistent with "Hour" in area, that i'm attentive to. That velocity isn't everywhere on the area of 186,000 Miles consistent with "2d" that's the fee of sunshine. contemporary area launches tension astronauts very critically (severe G's) purely getting as much as around 15,000 Miles consistent with Hour from a standing initiate on the launch pad. i won't be in a position to particularly think of the human physique accelerating from 0 to three velocity on the area of the fee of sunshine and ultimate intact. Please evaluate that with all seriousness earlier shifting on with those concepts. The human physique can purely face up to lots tension utilized onto it. i think of that area of the priority human beings have in understanding the huge modifications in the two velocities has to do with overlooking the words "consistent with 2d" and "consistent with hour" which I placed in citation marks above. that might assist you notice the adaptation, enable me convert 186,000 Miles consistent with 2d into Miles consistent with Hour... to try this, you could desire to multiply 186,000 situations 3,six hundred That equals 669,six hundred,000 Miles consistent with Hour and the closest we've come to that's approximately fifty 5,000 Miles consistent with Hour Regards, Zah

Answer 4

Helios I and Helios II were launched to orbit and measure the Sun. They set a speed record for spacecraft at 252,792 km/h (70.2 km/s).

Answer 5

The Voyager probes have managed ~40k mph tops.

Answer 6

Billions of watts of light pollution and none of it's going into space?

So, 300,000 km/second.
