The following are a list of spacecraft with a mass greater than 8,000 kg (17,637 lb), or the top three to any other orbit including a planetary orbit, or the top three of a specific category of vehicle, or the heaviest vehicle from a specific nation. All numbers listed below for satellites use their mass at launch, if not otherwise stated.
The only Universal Rocket to make it past the design phase was the UR-500 while the N1 was selected to be the Soviets' HLV for lunar and Martian missions. [60] The UR-900, proposed in 1969, would have had a payload capacity of 240 t (530,000 lb) to low earth orbit. It never left the drawing board. [61]
Last minute checks could then be carried out and the rocket launched. The rocket would have been able to carry a payload of up to 550 tonnes (540 long tons; 610 short tons) or 550,000 kg (1,210,000 lb) into LEO. Payload costs, in 1963, were estimated to be between $59 and $600 per kg (roughly $500 to $5,060 per kg in 2020 dollars [5]).
SN20 was stacked on top of Booster 4 on August 6, 2021 for a fitting test, [41] making it, for two years, the tallest rocket ever fully integrated. [83] B4 completed its first cryogenic proof test on December 17, 2021, [ 84 ] followed by a pneumatic proof test, another cryogenic proof test and a full-load cryogenic proof test.
Steve Eves formerly held the world record for the tallest and heaviest amateur rocket ever successfully launched. The rocket was 36 feet (11 m) tall and weighed 1,648 pounds (748 kg). [ 1 ] On Saturday April 25, 2009 Eves launched the 1/10 scale replica of the Saturn V rocket 4,441 feet (1,354 m) into the air, and successfully recovered it. [ 2 ]
Its first stage, Block A, was the most powerful rocket stage ever flown for over 50 years, with the record standing until Starship's first integrated flight test. [7] However, each of the four attempts to launch an N1 failed in flight, with the second attempt resulting in the vehicle crashing back onto its launch pad shortly after liftoff.

Viking was a series of twelve sounding rockets designed and built by the Glenn L. Martin Company under the direction of the U.S. Naval Research Laboratory (NRL). Designed to supersede the German V-2 as a research vehicle, the Viking was the most advanced large, liquid-fueled rocket developed in the United States in the late 1940s, providing much engineering experience while returning valuable ...
