Vienna-based startup Tumbleweed has shipped its first satellite, Oasis Alpha, to launch services provider Exolaunch ahead of a planned launch in July, marking what the company says is Austria’s first fully commercial satellite mission.
The milestone comes less than a year after Tumbleweed was founded in 2024, highlighting the company’s goal of simplifying access to space for organizations seeking to conduct microgravity research.
While Austria has participated in numerous international and academic space missions and recently commissioned its first military satellite, Oasis Alpha represents the country’s first satellite mission developed and operated on a fully commercial basis.
Satellite Developed in Less Than Nine Months
Tumbleweed said it designed, built and delivered Oasis Alpha in under nine months, with total development costs below €500,000 ($580,000).
The satellite is designed to carry specialized payload containers, known as pods, that allow customers to conduct experiments in microgravity without having to meet the extensive testing and certification requirements typically associated with space missions.
According to the company, the pods are engineered to contain any potential failures internally, reducing risks to the satellite and enabling first-time space users to fly experimental hardware more easily.
First Mission Fully Booked
The inaugural Oasis Alpha mission will carry payloads from four European customers: Delft University of Technology, the European Space Resources Innovation Centre, The Spring Institute for Forests on the Moon and Mass Balance.
Several of the participating organizations will be conducting their first experiments in space, aligning with Tumbleweed’s strategy of serving customers with limited or no previous spaceflight experience.
“Historically, things that have scaled in space are things where the end user doesn’t need to understand anything about space. When you use Google Maps, no one knows it’s a space-based service at all,” CEO Julian Rothenbuchner told Payload.
“We need to get to that point with microgravity.”
Expanding Into Reentry Missions
While Oasis Alpha is a free-flying satellite, Tumbleweed plans to expand its services by offering missions that allow customers to recover payloads after launch.
The company said future pods will be integrated into reentry capsules, enabling experiments and hardware to be returned to Earth for analysis. The first such mission is currently planned for 2027, and customer bookings have already been secured.
Tumbleweed also intends to increase the scale of payloads it can accommodate. The current Oasis Alpha mission carries payloads roughly the size of a beverage can, but the company aims to support payload capacities of up to 250 kilograms by 2029.
“My bet is we probably haven’t even seen the actual scaling applications yet,” Rothenbuchner said.
“Everything the industry is telling us is that there are probably way bigger things out there that we’re not even considering. We’ve barely scratched the surface.”
The company’s plans reflect growing interest in commercial microgravity research and the emergence of new platforms designed to lower barriers to entry for organizations seeking access to space-based experimentation.
