Aphelion Orbitals

Aphelion Orbitals is a New Jersey-based aerospace company founded in 2017 with the mission of providing reliable, low-cost, and frequent access to orbit for small satellite operators. The company is developing the Helios launch vehicle — a small, mass-produced nanosatellite launcher designed to deliver payloads up to 20 kg to sun-synchronous orbit on a regular, scheduled basis.

Unlike rideshare missions that require customers to fit within large constellation launch schedules, Aphelion's model emphasizes dedicated, on-demand launch windows for nanosatellite operators. The Trailblazer system targets even smaller payload classes, extending the company's reach into the picosatellite and femtosatellite markets.

Aphelion also develops nanosatellite buses and integrated spacecraft systems for commercial customers, positioning itself as an end-to-end provider for the rapidly growing small satellite segment. The company was established to address the growing launch backlog faced by nanosatellite developers seeking timely orbital access.
