Impulse Space Lunar Delivery Plan: Up to 6 Tons Per Year

Impulse Space's Lunar Cargo Ambitions

Impulse Space unveiled a comprehensive strategy on Tuesday to leverage its technology for transporting substantial cargo quantities to the moon, potentially as early as 2028.

Addressing a Market Need

The company intends to address what it identifies as a current deficiency in the market: the delivery of mid-sized payloads to the lunar surface. They aim to provide a solution for cargo that doesn't fit neatly into existing options.

Helios and the New Lunar Lander

Impulse Space plans to combine a newly developed lunar lander with its Helios high-energy kick stage. This pairing will enable the transport of tons of material to the lunar surface without the necessity for orbital refueling.

The goal is to deliver up to 6 tons of payload to the moon over two missions, offered at a competitive price.

Filling a Critical Payload Gap

Founded by Tom Mueller, formerly the propulsion chief at SpaceX, the startup contends that this capacity will bridge a “critical gap” in lunar payload logistics.

This gap exists for cargo exceeding the capacity of landers participating in NASA’s Commercial Lunar Payload Services program, yet remaining smaller than the payloads intended for the larger, human-rated landers under development by SpaceX and Blue Origin.

Payload Examples

Impulse Space specifies that payloads falling within the 0.5 to 13 ton range would benefit from this service. Potential cargo includes:

• Rovers
• Habitat modules
• Power generators
• Communications systems
• Lunar terrain vehicles

Proposed Architecture

The lander and kick stage will be launched via a conventional rocket and deployed into low Earth orbit. Helios will then transport the lander to low lunar orbit within a week.

Following this transfer, the two vehicles will separate, allowing the lander to initiate its descent to the lunar surface.

Leveraging Existing Expertise

Impulse Space possesses significant expertise in spacecraft engine development. Work is already underway on the lunar lander engine.

This engine utilizes the same fuel combination as the Saiph thrusters currently employed in the company’s small spacecraft, Mira.

Helios Development and Flight Schedule

Development of Helios is “already well into development,” with the initial flight targeted for late 2026.

The company anticipates conducting multiple Helios flights annually by 2028.

Challenges and Future Outlook

Despite the ambitious plan, execution risks remain. A lunar lander engine requires specific capabilities, including throttleability, restart functionality, and a high specific impulse for precise control in the vacuum of space.

Impulse Space indicated a degree of caution, stating its readiness to proceed “as dictated by industry demand and interest.” However, successful implementation would establish a new and expanded lunar delivery timeline.
