NASA Fast-Tracks $150M for Next-Gen Habitable Worlds Observatory by 2040s

NASA, pushing ahead with plans for the Habitable Worlds Observatory (HWO), a next-generation space telescope set to launch in the 2040s, has allocated $150 million in its 2026 budget—far more than the initial $3.3 million proposed. The agency has also awarded contracts to seven companies for key technology studies.

The HWO is designed to outperform all existing telescopes, detecting objects too dim for current instruments. Its capabilities will span exoplanet research and deep-space cosmology. Engineers are currently evaluating two mirror sizes: a six-metre option and an eight-metre alternative.

NASA has also tasked seven firms—Astroscale U.S., BAE Systems, Busek, L3Harris, Lockheed Martin, Northrop Grumman, and Zecoat—with studying critical technologies. Their work will cover mirror coatings, propulsion systems, and servicing methods needed for the telescope's construction and operation.

Meanwhile, two probe mission concepts, AXIS and PRIMA, remain under consideration. A decision on which to advance was expected by the end of the fiscal year, but no selection has been announced. The chosen probe will help shape future large telescope projects beyond HWO.

Looking further ahead, the next astrophysics decadal survey, Astro2030, will assess concepts for even larger space telescopes. NASA's long-term strategy depends on both HWO's success and the outcomes of the ongoing probe mission studies.

The $150 million budget boost signals NASA's commitment to HWO, with technology development now underway. The telescope's unprecedented sensitivity and scale will redefine space observation when it launches in the 2040s. Further decisions on probe missions and future telescope designs will follow in the coming years.
