Apex Unveils Larger Satellite Bus, Dubbed Comet

Spacecraft manufacturing startup Apex announced today that it is beefing up its product line with Comet, its largest satellite bus to date.  

Bus stats: Comet has a flat design that allows it to stack flat for launch, allowing more sats to ride on each rocket. It’s able to deliver 5 kW of power to payloads, making it well-suited for commercial and national security customers pursuing missions to LEO with high-power requirements, including direct-to-device constellations and advanced antenna systems. 

“From cell phone towers in space for consumer technology [to] unique sensing missions, or as an interceptor platform for Golden Dome, Comet is the clear choice to accelerate the most ambitious space missions,” Apex CEO Ian Cinnamon said in a statement.  

The Goldilocks effect: Apex now offers platforms in different sizes and configurations, aiming to ensure one will be just right for customers: 

  • The Aries, which can carry up to 150 kg (330 lbs) to LEO and 120 kg (265 kg) to GEO;
  • Nova, which can carry up to 300 kg (660 lbs) to LEO
  • Comet, which can carry more than 500 kg (1,100 lbs) to LEO

How we got here: It’s been less than a year since Apex announced it was entering the GEO market with a 200-kg (440-lb) ESPA-class vehicle built for that far-out orbit. Apex’s move into GEO is in response to customers operating in that orbit being willing to consider platforms that aren’t made-to-order for the first time, Cinnamon told Payload at the time.

The LA-based startup also closed a $200M Series C last month, led by Point72 Venture and 8VC. The significant funding news followed a major technical milestone for Apex: its first Aries bus celebrated its first operational year on-orbit in March.
