Inprentus wins TASA contract for CubeSat greenhouse gas observatory gratings

By AI, Created 11:08 AM UTC, May 20, 2026, /AGP/ – Inprentus has landed a Taiwan Space Agency contract to build convex diffraction gratings for a CubeSat greenhouse gas observatory, following a recent NASA award. The work expands the company’s role in compact space instruments aimed at climate monitoring and emissions tracking.

Why it matters: - Inprentus is moving deeper into space-based optics with contracts from both TASA and NASA. - The TASA project could help improve global greenhouse gas monitoring by shrinking spectrometer hardware into CubeSat form. - The contract also signals growing demand for high-precision gratings in compact satellites and other small space vehicles.

What happened: - Inprentus won a TASA contract to produce ultra-high-precision convex spherical diffraction gratings for an orbital greenhouse gas observatory. - The award follows Inprentus’ recent NASA contract for concave gratings for the ESIS-II solar mission. - TASA plans to use the gratings in a proving mission that combines a compact spectrometer, telescope and detector into a CubeSat. - The company said the CubeSat is about the size of a 1-gallon water jug.

The details: - The gratings are designed to detect infrared signatures of carbon dioxide and methane. - Inprentus will initially deliver two convex spherical gratings for ground testing and alignment of the prototype spectrometer. - The planned orbital mission is expected to map global greenhouse gas emissions by linking spectroscopic data with geolocation. - The system is designed to detect subtle spectral variations that indicate 0.2% increases above ambient atmospheric concentrations. - TASA plans to include five convex gratings in the final satellite design. - Each grating will be tuned to the spectral signatures of specific greenhouse gases. - The satellite is projected to be ready to fly by 2030. - The mission is expected to support climate monitoring, emissions tracking, atmospheric analysis and observation of environmental events such as the Hunga Tonga submarine volcano eruption in 2022. - Inprentus said the performance of its gratings comes from its digital ruler architecture and dynamic contact mode lithography technique. - The process allows precise control of the shape and placement of individual grating grooves. - Inprentus said the technology is especially important for curved optical surfaces, where precision affects light throughput and spectral resolution. - The extension of the technology to convex geometries is a technical milestone for the company. - Inprentus says the capability expands its market in space-based optics.

Between the lines: - The TASA win suggests Inprentus is becoming a more established supplier for missions that need compact, high-performance optics. - The focus on convex surfaces matters because miniaturized spacecraft need more optical performance in less space. - The company is also leaning on its technical heritage to position modern mechanical ruling as a continuation of older grating-making methods. - Subha Kumar, chief operations officer of Inprentus, said contracts from NASA and TASA validate the company’s ability to carry on Henry Rowland’s legacy with upgraded 21st century mechanically ruled gratings.

What’s next: - Inprentus will deliver the first two gratings for lab testing and spectrometer alignment. - TASA will continue developing the final satellite design around five tuned convex gratings. - The mission’s next major milestone is a targeted 2030 launch readiness date. - If successful, the orbital observatory could become a tool for routine greenhouse gas and atmospheric measurements from space.

The bottom line: - Inprentus is turning precision grating manufacturing into a growing space business, with TASA and NASA contracts reinforcing its position in small-satellite optics.
