Alpha Impulsion Signs the Zero Debris Charter

Alpha Impulsion joins the zero debris charter community

In recent years, we’ve witnessed more satellites being launched than in the past six decades combined. Today, it’s estimated that about 130 million pieces of debris larger than a millimeter are orbiting Earth. These objects pose serious threats to the active satellites that power our essential services, from communication and meteorology to climate research and navigation. The trend towards increasingly cluttered Earth orbits calls for immediate action if we want to sustain our future space ambitions.

Tackling Space Debris

The Zero Debris Charter, a collective initiative by ESA – the European Space Agency, aims to address this challenge by advancing a shared vision of space sustainability with clear goals for 2030.

  • Minimizing Collision and Breakup Risks: Keeping the likelihood of space debris generation through collisions and breakups below 1 in 1000.
  • Efficient Orbit Clearance: Achieving successful deorbiting of objects with a success rate of at least 99%.
  • Reducing Casualty Risk on Re-entry: Ensuring that the risk of harm from re-entering objects remains below 1 in 10,000, with a long-term goal of zero casualties.
  • Commitment to Transparency: Promoting the open sharing of information about space activities and debris mitigation.
  • Enhanced Tracking Capabilities: Providing accurate data on space objects as small as 5 cm in Low Earth Orbit, enabling better tracking and collision avoidance

Why it Matters to Alpha Impulsion

Of the 28,000 objects larger than 5 cm currently tracked by the US Space Surveillance Network, about 11% are discarded rocket upper stages and other mission-related remnant. Over 560 in-orbit fragmentations have been recorded, primarily due to residual fuel or energy sources that can be left in abandoned rocket stages. Over time, exposure to space’s harsh environment weakens these components, leading to leaks and the spontaneous explosion of residual fuels.

As a launch service provider, we recognize our responsibility in addressing these risks.

Our Approach to Reducing Space Debris

Our first step toward lowering our impact in space is to ensure the deorbiting of our rocket stage after it delivers satellites, one of our goals for the first orbital launch of Grenat in 2027. We are also working to minimize the risk of in-space explosions by using inherently safe fuels. High-Density Polyethylene and Liquid Oxygen cannot combust spontaneously without an external energy source, greatly reducing the potential for accidents.

As a signatory of the Zero Debris Charter, Alpha Impulsion is committed to advancing space safety and sustainability. Our ultimate goal is to help establish zero-debris policies as the industry standard, paving the way for a safer, sustainable space environment for all.
