In the world of commercial spaceflight, two massive rockets are poised to transform how we access space – Blue Origin’s New Glenn and SpaceX’s Falcon Heavy. Both vehicles represent the next leap in rocket technology, offering unprecedented capabilities at a lower cost through reusability. But how do these behemoths really compare? Let’s take an in-depth look at New Glenn and Falcon Heavy across key dimensions like design, performance, mission profiles, and competitiveness.

Overview of New Glenn and Falcon Heavy

Blue Origin New Glenn

New Glenn is a heavy-lift orbital launch vehicle currently under development by Blue Origin. Named after pioneering astronaut John Glenn, the rocket is designed for operational reusability to dramatically reduce launch costs. The vehicle consists of a reusable first stage powered by seven BE-4 engines and an expendable second stage with two BE-3U engines. New Glenn is planned to be available in two variants:

• A two-stage version with a height of 98 meters (321 ft) and a 7-meter (23 ft) diameter payload fairing
• A three-stage version with a height of 95 meters (313 ft), adding a third stage for high-energy orbits and interplanetary missions

Blue Origin is constructing New Glenn at its sprawling rocket factory in Florida, near Launch Complex 36 which the company leased and rebuilt to support New Glenn missions. An initial launch is expected no earlier than late 2024.

SpaceX Falcon Heavy

Falcon Heavy is a partially reusable heavy-lift rocket developed and operated by SpaceX. It is derived from the Falcon 9 vehicle and consists of a strengthened Falcon 9 first stage core with two additional Falcon 9 first stages acting as strap-on boosters. This configuration gives Falcon Heavy the highest payload capacity of any operational rocket.

With a height of 70 meters (230 ft) and a total of 27 Merlin 1D engines across its three cores, Falcon Heavy can lift over 63,800 kg (140,700 lb) to low Earth orbit in its fully expendable mode. However, SpaceX has optimized Falcon Heavy to recover all three first stage cores for reuse, which reduces its payload capacity but enables much lower launch costs.

Falcon Heavy completed its maiden flight in February 2018 and has since launched numerous operational missions for commercial and government customers from Kennedy Space Center in Florida.

Key Specifications Comparison

As evident from the table, New Glenn has the edge in payload capacity to both LEO and GTO, in reusable mode. Furthermore, New Glenn’s larger 7-meter fairing provides more volume for bulky payloads. New Glenn also uses LNG fuel which is cleaner and more efficient than Falcon Heavy’s RP-1 kerosene.

Reusability Approach

Both New Glenn and Falcon Heavy are designed for partial rocket reuse to enable lower launch costs. However, their approaches to reusability differ in a few key aspects:

New Glenn Reusability

Blue Origin is designing New Glenn’s first stage to be reusable up to 25 times. After stage separation, the booster will perform a vertical landing on a moving ship, similar to SpaceX’s drone ship landings. Blue Origin has already demonstrated this landing technology on a smaller scale with its New Shepard suborbital rocket.

However, New Glenn’s second stage will not be reusable. Blue Origin has stated that they don’t believe the performance hit and added complexity required for second stage reuse is worth it for their target markets and missions.

Falcon Heavy Reusability

SpaceX has taken reusability to the next level with Falcon Heavy. All three first stage cores – the two side boosters and the central core – are designed to land vertically for reuse. The side boosters return to land at SpaceX’s Landing Zones while the center core lands on a drone ship further downrange.

SpaceX has already demonstrated this triple landing feat on Falcon Heavy’s first commercial mission in April 2019. The two side boosters from that mission were reused on a subsequent Falcon Heavy launch, showcasing the rapid reusability of the system.

Like New Glenn, Falcon Heavy’s second stage is expendable. SpaceX briefly considered making it reusable but abandoned that approach to focus on its fully reusable Starship vehicle instead.

Mission Capabilities and Markets

New Glenn Missions

With its heavy lift capacity and voluminous fairing, New Glenn is well suited for a variety of missions:

• Launching large geosynchronous satellites, either directly to GEO or to GTO
• Deploying sizeable satellite constellations to LEO
• Lofting exploration missions to the Moon and beyond
• Carrying cargo and crew to the International Space Station (ISS)

Blue Origin has already signed up several commercial customers for New Glenn, including Eutelsat, mu Space, SKY Perfect JSAT, and Telesat. The company also has a launch contract with the U.S. Space Force.

Falcon Heavy Missions

Falcon Heavy’s unique capability is launching very heavy payloads to high-energy trajectories. Key applications include:

• Launching large national security payloads directly to GEO for the U.S. military
• Injecting interplanetary probes and telescopes to Earth escape trajectories
• Deploying big batches of satellites to LEO and GTO
• Sending cargo and crew to the Moon and Mars

SpaceX has won several high-profile government contracts for Falcon Heavy, such as launching NASA’s Psyche asteroid probe, Europa Clipper mission, and the GOES-U weather satellite.

Competitiveness and Outlook

New Glenn and Falcon Heavy are set to be the workhorses of the heavy-lift market in the coming years. Both vehicles offer distinct capabilities and advantages:

• New Glenn’s main strengths are its large payload volume, clean-burning methane engines, and robust reusability of up to 25 flights per booster. This could make it very competitive for high-volume satellite constellation launches. However, New Glenn has yet to prove itself in flight and is still several years away from operational service.
• Falcon Heavy, on the other hand, is flight-proven and has already demonstrated rapid reusability. Its ability to recover all three first stage boosters enables very low marginal launch costs.

Ultimately, the competitiveness of New Glenn vs Falcon Heavy will depend on the target market and specific mission requirements. For some applications like high-volume LEO constellations, New Glenn could be the more economical choice. For others like interplanetary exploration, Falcon Heavy remains the only commercial option with the necessary performance.

Looking ahead, both vehicles will likely see strong demand in the booming commercial space sector. As satellite operators build ever larger and heavier spacecraft, the capabilities of New Glenn and Falcon Heavy will be in high demand. Additionally, NASA’s Artemis program and other government exploration initiatives will require the unmatched power of these heavy-lift rockets.

In the longer term, the future of New Glenn and Falcon Heavy will be shaped by emerging super heavy-lift vehicles like SpaceX’s Starship and NASA’s Space Launch System. But for now, New Glenn and Falcon Heavy are set to dominate the heavy-lift market with their unique capabilities and low launch costs enabled by reusability. The competition between Blue Origin and SpaceX will only further accelerate innovation and push the boundaries of what’s possible in the commercial space domain.
