QuantX Labs’ TEMPO Mission First Optical Frequency Comb Launch to Orbit in 2025

Introduction

QuantX Labs, based in Adelaide, Australia, is at the forefront of precision timing and quantum sensing. In partnership with French in‑space logistics firm Exotrail, QuantX is preparing to launch the Optical Frequency Comb—a core part of its TEMPO optical atomic clock—into low Earth orbit late in 2025 aboard Exotrail’s spacevan™ on a SpaceX Falcon 9 rideshare QuantX Labs – Quantifying The Unknown. The project is underwritten by a $3.7 million grant from the Australian Space Agency’s Moon to Mars initiative, reflecting Australia’s commitment to sovereign space‑based navigation and timing.

Background on Optical Frequency Combs

Optical Frequency Combs were first pioneered around 2000 and garnered the Nobel Prize in Physics in 2005 for their role in precision spectroscopy and timing QuantX Labs – Quantifying The Unknown. These “combs” produce a spectrum of discrete, equally spaced optical frequencies that serve as an ultra‑stable ruler for measuring time and frequency. On the ground, combs have revolutionized telecommunications and metrology. Flying one in space opens new frontiers in deep‑space communications, navigation, and synchronized Earth observation.

“This launch represents not only a breakthrough for our TEMPO technology but also the culmination of countless hours of hard work by our engineers and physicists. We have managed to deliver this outcome in much less time and at much less cost than is traditional,” said Professor Andre Luiten, Managing Director of QuantX Labs QuantX Labs – Quantifying The Unknown.

TEMPO Atomic Clock System

The TEMPO (Time‑based Precision Oscillator) system integrates the Optical Frequency Comb with cutting‑edge lasers, atomic references, and control electronics. Together, they form an optical atomic clock capable of 10⁻¹⁸ timing precision—orders of magnitude better than current space clocks Orbital Today. TEMPO’s modular design allows the comb to serve as a subsystem ahead of the full payload, reducing risk and enabling iterative technology maturation.

Environmental Testing and Validation

QuantX’s Optical Frequency Comb has successfully endured a battery of harsh environmental tests designed to simulate launch and on‑orbit conditions:

Test Type Simulated Condition Status
Temperature Extremes –40 °C to +85 °C cycling Passed
High Vacuum 10⁻⁶ Torr level Passed
Vibration & Shock Random and sine vibration profiles Passed
Radiation Exposure Total ionizing dose > 10 kRad(Si) Passed

Exotrail’s spacevan™ made its maiden flight on SpaceX’s Transporter‑9 mission in November 2023, demonstrating its in‑orbit transfer capabilities before handling the QuantX payload exotrail.com. This upcoming flight will be the spacevan’s second orbital mission, leveraging that flight heritage to ensure mission success

Future Applications and Impact

Beyond demonstrating an Australian sovereign timing capability, this mission lays groundwork for next‑generation navigation, deep‑space networks, and Earth observation. By flying optical clocks in space, QuantX aims to supplement or even replace existing GPS and GNSS systems, offering enhanced accuracy and resilience against signal interference Orbital Today. Dr. Sebastian Ng, QuantX’s PNT Program Lead, notes that insights from the frequency comb deployment will inform the development of the full TEMPO payload on subsequent missions.

SpinLaunch is challenging the long-standing reliance on chemical rockets by developing a kinetic launch system. Instead of burning massive amounts of fuel, the system uses a large vacuum-sealed centrifuge to accelerate satellites and other payloads before hurling them into the upper atmosphere.

The principle behind this approach is not new—medieval trebuchets used similar kinetic energy concepts to launch projectiles. However, modern materials, electronics, and engineering advancements have made it possible to scale this method for space launches.

𝐇𝐨𝐰 𝐒𝐩𝐢𝐧𝐋𝐚𝐮𝐧𝐜𝐡 𝐖𝐨𝐫𝐤𝐬

SpinLaunch’s orbital accelerator is essentially a massive, high-speed spinning arm enclosed in a vacuum chamber. Here’s how it functions:

  • A payload (satellite or spacecraft) is attached to the rotating arm inside the chamber.
  • The system spins the payload at incredible speeds (up to 5000 mph) using electric motors.
  • At the precise moment, the arm releases the payload, flinging it into space.

Unlike rockets, this system does not require staging, meaning there are no parts to be discarded mid-flight.

  • Lower cost: Fuel is one of the largest expenses in traditional rocket launches. SpinLaunch eliminates this entirely.
  • Eco-friendly: No carbon emissions or fuel combustion reduces environmental damage.
  • High launch frequency: The system can launch satellites multiple times a day without requiring extensive refurbishment.

𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞𝐬 𝐅𝐨𝐫 𝐒𝐩𝐢𝐧𝐋𝐚𝐮𝐧𝐜𝐡

While the idea is promising, several technical hurdles remain:

  • Extreme G-forces: The payload must withstand forces of up to 10,000 Gs, requiring special engineering.
  • Atmospheric resistance: The object must pierce through the lower atmosphere at high speeds.
  • Payload limitations: Currently, only small satellites can be launched, as the system is not designed for human travel.

SpinLaunch has created a system called the kinetic launch system. This system can send objects into space. The process involves using a large spinning arm. The arm throws objects into the sky at high speeds. This is different from traditional rockets. Rockets use a lot of fuel to escape Earth’s gravity. The kinetic launch system uses less fuel. It relies on spinning energy instead. SpinLaunch is the company that developed this technology. They believe it is a more efficient way to reach space.

𝐎𝐭𝐡𝐞𝐫 𝐈𝐧𝐧𝐨𝐯𝐚𝐭𝐢𝐯𝐞 𝐋𝐚𝐮𝐧𝐜𝐡 𝐌𝐞𝐭𝐡𝐨𝐝𝐬

SpinLaunch is not the only company reimagining space travel. Other exciting satellite launch alternatives include:

Technology Developer Key Benefit
Reusable Rockets SpaceX Reduces costs by landing and reusing boosters
Air-Launched Rockets Virgin Orbit Flexible launch locations
3D-Printed Rockets Relativity Space Faster, cheaper manufacturing
Space Tugs Momentus Moves satellites after launch

Each of these alternative launch methods contributes to making space more accessible, reducing dependence on traditional rocket launches.

𝐓𝐡𝐞 𝐅𝐮𝐭𝐮𝐫𝐞 𝐎𝐟 𝐒𝐩𝐢𝐧𝐋𝐚𝐮𝐧𝐜𝐡

SpinLaunch has already completed multiple successful test flights and is now working toward building a coastal launch facility for orbital launches.

Their next steps include:

  • Developing a larger system to support heavier payloads.
  • Partnering with organizations like NASA, Airbus, and Cornell University.
  • Expanding their system to be a primary method of small satellite deployment.

If successful, kinetic launch technology could redefine the economics of space travel.

𝐅𝐚𝐜𝐭𝐬 𝐀𝐛𝐨𝐮𝐭 𝐊𝐢𝐧𝐞𝐭𝐢𝐜 𝐋𝐚𝐮𝐧𝐜𝐡

  • SpinLaunch’s system is 10 times more energy efficient than chemical rockets.
  • NASA’s cannon-launched projectiles inspired parts of this design.
  • The launch speed is faster than a bullet! SpinLaunch hurls objects at Mach 6 speeds.
  • Ancient war machines like trebuchets used similar physics.
