In February 2022, Pixxel, an Indian-American space technology company specializing in hyperspectral Earth observation, selected Dawn Aerospace, a New Zealand-based aerospace firm, to provide propulsion systems for its satellite constellation. This collaboration aimed to enhance Pixxel's ability to monitor Earth's health through advanced imaging technologies. ([spacewatch.global](

Pixxel's Hyperspectral Imaging Constellation

Founded in 2019, Pixxel is dedicated to building a constellation of hyperspectral imaging satellites designed to deliver high-resolution spectral intelligence across visible and infrared wavelengths. The constellation roadmap includes the Firefly and Honeybee constellations, each with specific technical specifications and operational parameters. ([support.pixxel.space](

The Firefly constellation, Pixxel's operational hyperspectral constellation, delivers high-resolution VNIR (Visible–Near Infrared) imagery designed for frequent global monitoring. The Honeybee constellation, planned for future launch, will have expanded hyperspectral coverage from visible to shortwave infrared. ([support.pixxel.space](

Dawn Aerospace's Role in the Collaboration

Dawn Aerospace specializes in satellite propulsion systems and has been providing propulsion modules to Pixxel's satellites. These modules enable Pixxel's satellites to maneuver into their desired orbit post-launch, manage in-space operations, and deorbit responsibly at the end of their mission life. ([news.satnews.com](

In 2022, Dawn Aerospace announced that it was providing satellite propulsion systems to Pixxel, supporting the company's mission to build a health monitor for the planet through a constellation of hyperspectral imaging small satellites. ([spacewatch.global](
