Norsk Elektro Optikk AS (NEO), a leading payload provider of high-performance hyperspectral imaging systems, has signed a contract with the European Space Agency (ESA) to complete the design and manufacturing of HyperNOR S-1280, the first spaceborne instrument in the HySpex HyperNOR family. The next-generation in-orbit hyperspectral demonstrator is designed to unlock the full potential of extended Short-Wave Infrared (eSWIR, 950–2500 nm) imaging from space.

The HyperNOR S -1280 instrument is being realised under ESAs General Support Technology Programme (GSTP), with support from the Norwegian Space Agency (NOSA). The contract enables a complete payload development pathway—from Qualification Model (QM) to Flight Model (FM), culminating in launch as an In-Orbit Demonstrator (IOD) in the first half of 2028. By combining qualification, flight readiness, and in-orbit validation within a single framework, GSTP accelerates the transition of HySpex’s proven hyperspectral sensor technology from airborne and laboratory domains into space, while reducing risk and establishing a robust foundation for future operational missions and constellations.

HyperNOR S-1280 represents a significant advancement in hyperspectral Earth observation. As an ESA-supported GSTP/IOD mission, it is designed to close the commercial eSWIR gap in space-based imaging, enabling a new generation of high-impact applications for downstream providers.

“The HyperNOR S-1280 represents a critical step forward in bringing high-quality, calibration-grade hyperspectral data into space,” says Lars O. Lierstuen, Head of Space & Business Development at NEO. “By combining high spatial resolution with robust eSWIR coverage, we are enabling continuity from lab to orbit and paving the way for next-generation hyperspectral constellations.”

Sceye, a pioneering aerospace company specializing in material science and the manufacture of High-Altitude Platform Systems (HAPS), proudly announces the successful completion of a full diurnal flight in the stratosphere, marking a significant milestone in the journey toward long-duration flights powered by solar energy.

The HAPS launched from Sceye's New Mexico facility at 7:36 AM MST on August 15th and landed the following day at 12:21 PM MST after successfully completing all designated flight test points. This endeavor demonstrates the capability of utilizing solar power during daylight hours while employing battery capacity for overnight flights, showcased by the advanced technology now poised to sustain operations over months or even years.

The HAPS carried two HySpex hyperspectral imagers (HSI) for Norsk Elektro Optikk AS (NEO): a Mjolnir V-1240, owned by the U.S. Geological Survey (USGS), and a SWIR-640 customized for methane detection, featuring 5- and 3.4-meter ground sampling distances (GSD) from 70,000 feet. Both were tailored for high-altitude operations. The two HSIs operated side-by-side, enabling hyperspectral data collection across the 400-1000nm and 1350-2500nm wavelength ranges.

“It is hard to grasp the amount of information that can be recovered from HSI, but it is safe to say that this platform is a game changer when it comes to remote sensing with natural light. From vegetation, farming, and mineral exploration to hydrocarbon leaks and surveillance” says Martin Løvøy, Research Scientist at NEO and a part of the payload team, present at the Roswell flight.

HySpex's third successful stratospheric flight significantly advances NEO’s high-altitude systems strategy. While this achievement is notable, the work continues as the team returns to Norway with vast amounts of data. This data will be processed into geology maps, hydrocarbon detection maps, and methane detection maps.

“With this flight, we hope to demonstrate our detection limit for methane gas from the stratosphere. The hyperspectral cameras from HySpex aboard the Sceye HAPS provide a superb turnkey solution for environmental monitoring, with the distinct advantage of long-duration stratospheric operations,” says Karina Strøm, Research Scientist at NEO, who also participated in the Roswell flight.

HySpex continues to prove its expertise by delivering high-quality hyperspectral data across diverse environmental conditions, showcasing the adaptability of its products. Sceye's advanced payload suite, featuring multiple sensors, marks a significant step toward real-time environmental monitoring and mapping that addresses critical global issues, including, but not limited to, flooding, wildfires, and pollution, such as gas leaks or plastics.

Sceye has conducted a total of twenty test flights, with two additional flights scheduled for 2024, further refining the platform in anticipation of commercialization.
