UP Aerospace is a privately held American suborbital launch services company founded by aerospace engineer Jerry Larson, a former Lockheed Martin engineer, with origins dating to 1998 and formal incorporation in 2004. The company is headquartered in Denver, Colorado, and conducts all of its launches from Spaceport America near Upham, New Mexico, where it was the first company to fly from the newly built spaceport. UP Aerospace's primary product is the SpaceLoft XL, a solid-fuelled sounding rocket capable of carrying research, educational and government payloads to suborbital altitudes, with parachute recovery of the payload section; the company has also flown smaller SL-series rockets. UP Aerospace has supported NASA's Flight Opportunities programme, Los Alamos National Laboratory, university researchers and U.S. military customers, and had completed around 21 SpaceLoft missions with a mixed flight-success record by the mid-2020s. The company has also announced development of an orbital small-satellite launch vehicle, Spyder, though this has not yet flown. UP Aerospace remains an active, privately held company under president Jerry Larson, operating as one of the longest-running commercial suborbital launch providers in the United States.

Zendir is a Canberra, Australia software company developing a cloud-based spacecraft digital twin and mission validation platform. The platform enables satellite developers and operators to build simulation environments that mirror their spacecraft's hardware and software — including hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing configurations — without needing deep simulation engineering expertise. Zendir's drag-and-drop interface lowers the barrier to creating realistic spacecraft simulations for mission planning, fault analysis, operator training, and pre-launch validation. As the small satellite market grows with operators having limited specialized engineering staff, tools like Zendir that democratize rigorous simulation are increasingly valuable. The company is based in Australia's emerging space ecosystem (Canberra/ACT) and has received support from the Australian Space Agency.
