Superheavy Rockets Promise Cheaper, Bigger Space Telescopes: A New Era for Astronomy?
January 17, 2026
By carrying up to ten times more mass to orbit and featuring broader bodies, these rockets reduce the need for folding or origami-like deployments that Webb required, lowering mission risk and cost.
The larger payloads and wider fairings of Starship and New Glenn could eliminate complex mirror deployment, cutting risk and expense for future space telescopes.
Risks include whether these rockets will perform as advertised and whether cost savings will materialize, requiring balance between ambition, cost discipline, and feasibility.
Challenges remain, including potential underperformance or higher costs, the need to manage astronomers’ ambitions within budgets, and careful program planning to maximize scientific return.
Superheavy-lift rockets like Starship and New Glenn could dramatically lower the cost of placing large telescopes in orbit by delivering far more mass per launch and enabling wider telescope dimensions.
Efforts aim for Webb-grade performance at lower costs, potentially allowing several telescopes to launch within the same budget.
Three telescope concepts stand to gain from heavy-lift: Origins (a deep infrared telescope), Prima (a smaller infrared option), and GO-LoW (a 100,000-element very low-frequency radio array), all becoming more sensitive and cost-effective.
Additionally, an X-ray telescope with thicker mirrors and GO-LoW—comprising 100,000 small modules—are being explored as beneficiaries of heavier-lift capabilities, enhancing multi-wavelength potential.
Today’s astronomy is limited by the cost and complexity of deploying large, space-based observatories, with Webb illustrating high price tags and folding-mechanism risks.
Space-based observations are essential to access broader spectra and detect colder and hotter objects, but full-spectrum observatories remain costly under current paradigms.
An X-ray telescope with Webb-like sharpness and thicker mirrors could be another beneficiary of heavy-lift rockets, boosting X-ray performance.
The goal is to achieve costs at or below Webb’s, enabling NASA to fly multiple new observatories rather than a single flagship, accelerating progress across wavelengths.
