Spacecraft of the Future: New Glenn vs Starship

In this article, we compare the rockets of the future. These are New Glenn and Starship, the heavy rockets built by leading private aerospace companies Blue Origin and SpaceX.

Starship vs New Glenn: the battle for space

We previously compared New Glenn and Neutron and also looked at the Blue Origin vs. SpaceX competition from a more general perspective. Let’s just say the latter competition has lasted 20 years, and it is a struggle between two completely different approaches to space exploration. While SpaceX initially relied on the delivery of goods into orbit, Blue Origin chose space tourism. Eventually, both companies achieved impressive results, but it’s time to combine approaches to achieve more. These systems can deliver cargo and astronauts not only to near-Earth orbits, but also to the Moon and Mars.

Blue Origin CEO Jeff Bezos named New Glenn after John Glenn, the first USA astronaut to orbit the Earth. Blue Origin publicly announced its intentions to build an orbital launch vehicle two years ahead of SpaceX, in September 2015.

And now, let’s try to determine who is top dog between New Glenn vs. Starship.

New Glenn vs. Starship: Size Comparison

The picture above shows that both rockets are bigger than the Statue of Liberty, but Starship is the biggest. It is 22 meters bigger than New Glenn and 27 meters bigger than the main US statue. In addition, the SpaceX ship is two meters wider than the Blue Origin rocket in diameter (9 versus 7). However, the Starship itself is only 50 meters high; the remaining 70 meters is the first stage of the Super Heavy (or, more simply, the SpaceX Falcon Heavy cargo rocket, but without side boosters and with different engines). At the same time, SpaceX assures that Starship will be able to fly not only in the basic modification (Starship + Super Heavy) but also in three other variants:

• Starship Cargo,
• Starship Lunar Lander,
• Starship Tanker (for refuelling in space or on other planets).

On the other hand, New Glenn can only offer a standard 2 or 3-stage modification with a payload fairing up to 22 m high.

Is Blue Origin’s New Glenn rocket more powerful than SpaceX’s Starship?

No. New Glenn will be able to carry 45 tons of payload to LEO and 13 tons to GTO. No doubt, this is more than most modern rockets can offer. But it is still 17 tons less than Falcon Heavy can carry. You ask why is New Glenn so much bigger than Falcon Heavy, but has less payload capacity? The answer is engines.

Starship vs New Glenn engine comparison

The Falcon Heavy’s payload advantage comes from two side-boosters and more powerful engines. The Falcon Heavy has a total of 27 Merlin 1D liquid engines (9 in each booster and 1 stage), developing thrust above sea level of 852 kN each. And what about New Glenn? The first stage of the New Glenn has seven BE-4 engines with a thrust of 2400 kN, and its second stage has two BE-3U engines with a thrust of 1100 kN. A simple addition tells us that the total thrust of the Falcon Heavy is 23,000 kN versus 19,000 kN for the New Glenn. But Starship surpasses them both! It is equipped with 39 Raptor 2 engines of 2000 kN thrust (33 in the first stage, 6 in the second), which allows it to handle a payload of up to 150 tons!

So is Starship the most powerful rocket?

The answer is obvious. Comparing Falcon Heavy, New Glenn rocket and Starship, the latter wins.

New Glenn vs. Starship: Reusability

Are Starship and New Glenn reusable? This is perhaps the most important metric after power and capacity, as it directly affects the final launch cost. Let’s agree, you will spend much less money on the production of a new rocket if you can reuse some of its parts. SpaceX promise that both stages of Starship will be reusable, while Blue Origin is more restrained in their statements. The company’s website states that the New Glenn will have a reusable first stage, but it will be reused up to 25 times. SpaceX do not brag about the number of re-launches; the latter speak for themselves. Falcon 9 launch statistics show that the company could use the same first stage 11 times!

What will fly first, Starship or New Glenn?

There’s no straightforward answer to this question. On 13 October 2024, SpaceX impressed everyone with another successful test. The first stage of the Starship Super Heavy was caught by the “chopsticks” of the launch tower seven minutes after launch, while the upper Starship stage reached suborbital space. On 22 October, SpaceX representatives announced that Super Heavy had returned to the Starbase for its sixth scheduled test flight. SpaceX’s Starship is steadily approaching its first commercial flight, and we may witness this historic event as early as the first half of 2025.

Unlike the bold Elon Musk, Jeff Bezos and the Blue Origin team take a more conservative approach. They refrain from making bold promises, simply stating they’ll fly when they’re ready.

On 26 September 2024, Blue Origin successfully tested the New Glenn’s upper stage and is now preparing for a NASA demonstration mission to test the technology of its orbital transport vehicle, Blue Ring. This launch is scheduled for November 2024.

“We’ll have a launch-ready rocket next month,” said Jarrett Jones, senior vice president for New Glenn at Blue Origin, during his speech at World Space Business Week on 16 September. “We’re launching in 2024.” Will Blue Origin’s New Glenn beat SpaceX’s Starship to the first launch? We might find out later this year.

May the best rocket win

The space race has changed significantly in the 21st century. Now, players focus on speed, affordability, and reliability rather than the number of achievements. So far, SpaceX has the lead in the race of New Glenn vs Starship, but the competition never rests. After all, earning NASA’s trust means securing multibillion-dollar contracts for sending rockets to the Moon and Mars, along with international recognition of the company’s technical leadership. And that, without any doubt, is a major incentive.
