In the quest for efficient interplanetary missions, the idea of using a small, inexpensive spacecraft equipped with a substantial fuel tank presents an innovative solution. Such a spacecraft, exemplified by Micocosm, Inc.'s proposed Hummingbird spacecraft, aims to revolutionize the process by making preliminary scouting missions feasible. A spacecraft that can provide the propulsion necessary to reach other planets while also being reproducible, relatively light, and inexpensive could serve as a robust catalyst for larger missions in the inner solar system.
The Hummingbird Spacecraft
The Hummingbird is designed as a versatile platform intended to visit nearby planets and asteroids, equipped with the basic capabilities needed for scouting missions. One key advantage of using a less costly spacecraft like Hummingbird is that it can gather initial data about a target, which can subsequently inform and reduce the financial burden on larger missions.
The efficiency of large space missions often hinges on accurate preliminary data. The Hummingbird spacecraft is tailored to act as a propulsion system while accommodating payloads such as radiation-hardened CubeSat components alongside larger, exchangeable equipment like telescopes. Its propulsion system, powered by hydrazine fuel, is capable of considerable energy output.
Mass and Propellant Capacity
The Hummingbird is notably lightweight, with an expected "Dry" weight (including all components except fuel) of 25 kg. When fully fueled, the "Wet" weight reaches approximately 80 kg, providing a robust thrust-to-weight ratio. The spacecraft is anticipated to achieve an orbital speed capable of generating a delta-V of 3.5 km/s, essential for reaching remote targets, including near-Earth asteroids, Mars, or even the moons of Mars.
Propulsion System
| Propulsion Component | Description | Specifications |
|---|---|---|
| Engine Type | Hydrazine propulsion | N/A |
| Dry Weight | Weight without fuel | 25 kg |
| Wet Weight | Weight with fuel | 80 kg |
| Delta-V Performance | Speed increase to reach targets | 3.5 km/s |
| Target Reach | Potential destinations | Mars, Venus, Lagrange points |
Cost Efficiency in Missions
One of the most pronounced advantages of a spacecraft like Hummingbird is its ability to drastically reduce the costs associated with extensive missions. The space exploration field is often highly restricted by budgets, leading mission designers to seek innovative alternatives for preliminary observations and data collection.

Interchangeable Payload and Future Operations
The Hummingbird's payload can be modified as necessary, allowing flexibility based on the mission’s objectives. The concept of interchangeable payloads means that a single spacecraft design can be adapted for various missions beyond its initial purpose. This aspect showcases the potential application of Hummingbird in ongoing and future projects in planetary science and interplanetary exploration.
Future of Interplanetary Missions
While a prototype of the Hummingbird spacecraft was presented in 2013, advancements in launch technologies and spacecraft design since then raise hopes for its potential revival. The aerospace field has witnessed a significant reduction in launch costs, with companies like SpaceX revolutionizing the market through the development of re-usable launch vehicles.
Considerations for CubeSat Operations
Despite the advantages, the initial design of Hummingbird did not elaborate extensively on CubeSat operations, such as communication management, attitude control, and coordination when interacting with other satellites or ground control. The handling of these operations in future iterations of the Hummingbird concept remains a critical consideration.
Economic and Strategic Implications
The implementation of Hummingbird could alter the economic landscape of space exploration. The advantages of less costly exploratory missions could broaden participation in planetary science across both governmental and non-governmental organizations. Moreover, it could enhance the strategic position of organizations willing to invest in these preliminary scouting missions.
| Aspect | Implication |
|---|---|
| Cost Reduction | More missions become possible for non-major space agencies. |
| Mission Flexibility | Adaptive payloads can be developed based on evolving scientific priority. |
| Enhanced Data Collection | Affordable scouting missions can precede larger, costly missions. |
| Increased Accessibility | Smaller agencies and educational institutions can partake in space missions. |
The scarcity of low-cost options in space exploration may hinder the progression of scientific knowledge. Hummingbird stands as a significant proposal towards rectifying this, potentially prompting further investments in science and technology that seek to venture beyond Earth.
