To be able to reach space, we need rockets. Rocket engines work by action and reaction (“To every action, there is always opposed an equal reaction”, see notes 1) and push rockets forward simply by expelling their exhaust in the opposite direction at high speed and can, therefore, work in the vacuum of space. Space rockets are usually enormous in size because the bigger the rocket is, the more thrust can be produced by its engine and can carry more weight into orbit. Here are the top 12 tallest rockets ever launched in the history of space exploration.
List of the tallest rockets ever launched [as of April 2023]
12. Atlas V: 58.30 meters (191.27 feet)
- Height: 58.30 meters (191.27 feet)
- Diameter: 3.81 meters (12.5 feet)
- Mass: 334,500 kg (737,400 lb)

Atlas V is an expendable launch system. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing.
Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage.
Atlas V is commonly used for interplanetary missions, military payloads and cargo runs to the International Space Station. As of 2022, Atlas V has had 96 launches with no complete failures, making it among the most reliable in the world.

Energia was a super-heavy rocket built by the Soviet Union in the 1980s as part of the Buran program (Soviet counterpart of the Space Shuttle). It has flown into space just twice (May 15, 1987, and November 15, 1988).
Maybe not the tallest rocket ever launched, but Energia was a beast for sure. It was the 4th most powerful rocket (after N1, Saturn V, and Space Shuttle) launched ever. If we discount the unsuccessful N1 rocket, it was the third most powerful rocket ever.

As of 2022, Falcon Heavy is the world’s most powerful operational rocket. Designed and manufactured by SpaceX, it is a partially reusable heavy-lift launch vehicle.
SpaceX conducted Falcon Heavy’s first test flight on February 6, 2018, at 3:45 p.m. EST (20:45 UTC). The rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk as a dummy payload.
Falcon Heavy was designed to carry humans into space beyond low Earth orbit, especially to the Moon, Mars, and potentially to asteroids for mining. But Elon Musk, the founder and the CEO of SpaceX, does not plan to apply for a human-rating certification to carry NASA astronauts. By the early 2020s, the BFR (“Big Falcon Rocket”) will replace Falcon Heavy and other current Falcon launch vehicles.

It is the largest type of the Delta IV rocket family and is the world’s fourth-highest-capacity rocket in operation, with a payload capacity half of SpaceX’s Falcon Heavy rocket. It is manufactured by United Launch Alliance.
5. Ares I-X: 94.2 meters (309 feet)
- Height: 94.2 meters (309 feet)
- Diameter: 5.5 meters (18 feet)
- Payload to LEO: 25,400 kg (56,000 lb)
- Max. Thrust: 15,000 kN (3,372,134 lbf)
- First (and only) launch: October 28, 2009

The now-canceled Ares I was the crew launch vehicle that was being developed by NASA as part of the Constellation program. Ares I-X was the first-stage prototype of Ares-I. It was launched on October 28, 2009.
Ares I rockets were intended to launch Orion crew exploration vehicles. But, now NASA is developing the Space Launch System (SLS) to launch the Orion spacecraft.
4. Artemis: 98 meters (322 feet): the most powerful [successful] rocket ever launched

- Max. Thrust: 45,400 kN (10,200,000 lbf)

N1 was the Soviet counterpart to NASA’s moon rocket, Saturn V. It was designed with crewed extra-orbital travel in mind (i.e. moon landing). Its first stage still remains the most powerful rocket stage ever built. However, the development of the rocket was underfunded and rushed.
N1’s development started in October 1965, almost four years after United States’ Saturn V. The project was badly derailed by the death of its chief designer Sergei Korolev (1907 – 14 January 1966, the lead Soviet rocket engineer and spacecraft designer during the Space Race) in 1966.
Each of the four attempts to launch an N1 failed. During the second launch attempt, the N1 rocket crashed back onto its launch pad shortly after liftoff and exploded, resulting in one of the largest artificial non-nuclear explosions in human history.
The N1 program was suspended in 1974 and was officially canceled in 1976. Along with the rest of the Soviet crewed lunar programs, the N1 was kept secret almost until the collapse of the Soviet Union in December 1991. Information about the N1 was first published in 1989.
2. Saturn V: 110.6 meters (363 feet), The biggest and tallest rocket ever built (and successfully launched)
- Height: 110.6 meters (363 feet)
- Diameter: 10.1 meters (33 feet)
- Width: 15 meters (49 feet)
- Mass: 2,970,000 kg (6,540,000 lb)
- Payload to LEO: 140,000 kg (310,000 lb)
- Payload to TLI: 48,600 kg (107,100 lb)
- Max. Thrust: 35,100 kN (7,891,000 lbf)
- First flight: November 9, 1967 (Apollo 4)
- Last flight: May 14, 1973 (Skylab)

The Saturn V was an American human-rated expendable rocket used by NASA between 1967 and 1973. The three-stage liquid-fueled super heavy-lift launch vehicle was developed to support the Apollo program for human exploration of the Moon and was later used to launch Skylab, the first American space station.
The Saturn V was launched 13 times from the Kennedy Space Center in Florida with no loss of crew or payload. As of 2022, the Saturn V remains the tallest, heaviest, and most powerful rocket ever brought to operational status.

Watch the liftoff of the mighty Saturn V rocket:
1. SpaceX Starship: 120 meters [394 feet]
- Height: 110.6 meters (363 feet)
- Diameter: 9 meters (30 feet)
- Mass: 5,000,000 kg (11,000,000 lb)
- Payload to LEO: 150,000 kg (330,693 lb)
- Max. Thrust: 74,500 kN (16,700,000 lbf)
- First flight: April 20, 2023 (failed)
SpaceX is developing Starship, a super heavy-lift space launch vehicle. With a height of 120 meters (394 feet) and a liftoff mass of 5,000 metric tons, Starship is the largest and most powerful reusable launch vehicle ever built.
It was first launched on April 20, 2023, but the first test was a failure. The rocket lost several engines after the launch, and the vehicle reached a maximum altitude of 39 km (24 miles). The spacecraft was unable to separate from the booster and the rocket was intentionally destroyed by commanding the flight termination system.
Watch: how big SpaceX rockets really are
Visual Effects Youtuber “Corridor Crew” (see his Youtube channel) put together a video that shows off SpaceX’s rockets (Falcon 9, Falcon Heavy, and BFR) in real-life situations.

Notes
- Newton’s third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
- Low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi) (orbital period of about 88 minutes), and 2,000 kilometers (1,200 mi) (orbital period of about 127 minutes).
- A geostationary orbit, geostationary Earth orbit, or geosynchronous equatorial orbit (GEO) is a circular orbit 35,786 kilometers (22,236 mi) above the Earth’s equator and following the direction of the Earth’s rotation. An object in such an orbit has an orbital period equal to the Earth’s rotational period (one sidereal day) and thus appears motionless, at a fixed position in the sky, to ground observers.
- A trans-lunar injection (TLI) is a propulsive maneuver used to set a spacecraft on a trajectory that will cause it to arrive at the Moon.
