Former Google CEO plans to singlehandedly fund a Hubble telescope replacement

Paper: The Lazuli Space Observatory: Architecture & Capabilities
Named for the deep sky blue of the rock Lapis lazuli, Lazuli is an optical space telescope with a mirror diameter of 3.1 meters (by comparison, the primary mirror of the Hubble Space Telescope is 2.4 meters). It is intended to launch as early as late 2028 and begin scientific operations in 2029.
There are some notable differences between Hubble and Lazuli, starting with the orbit. Lazuli will be located much farther from Earth, in an elliptical orbit with an apogee of 275,000 km and a perigee of 77,000 km, the latter distance about twice as high as geostationary orbit. This will afford the telescope a much clearer view than Hubble, located about 500 km above Earth and increasingly affected by the passage of Starlink and other communications satellites in its observations. At this higher altitude the Lazuli team believes it can maintain control of the telescope at all times and have a rapid data downlink.
The other three telescopes that will be funded by the Schmidts will be based on the ground, in the southern and western United States, but they are no less innovative than Lazuli. All three of the proposed telescopes are modular and take advantage of recent advances in computing power, storage, and AI processing and analyzing data.

Today at a meeting of the American Astronomical Society, Schmidt Sciences, a foundation backed by billionaires Eric and Wendy Schmidt, announced one of the largest ever private investments in astronomy: funding for an orbiting observatory larger than NASA’s Hubble Space Telescope, along with funds to build three novel ground-based observatories. The project aims to have all four components up and running by the end of the decade.
“We’re providing a new set of windows into the universe,” says Stuart Feldman, president of Schmidt Sciences, which will manage the observatory system. Time on the telescopes will be open to scientists worldwide, and data harvested by them will be available in linked databases. Schmidt Sciences declined to say how much it is investing but Feldman says the space telescope, called Lazuli, alone will cost hundreds of millions of dollars.

The observatory system is something of a departure for Schmidt Sciences, which usually hands out grants to scientists and their projects, Feldman says. With the new investment, Schmidt Sciences will lead the development and operation of the observatories. The foundation was already supporting early efforts for the three ground-based projects, but it decided last year to consolidate them into one program and add the Lazuli space telescope. “We told people to go and do it,” Feldman says. “There are real signatures on real agreements.”

Paper: The Lazuli Space Observatory: Architecture & Capabilities
Website of the program: The Eric and Wendy Schmidt Observatory SystemThe Lazuli Space Observatory is a 3-meter aperture astronomical facility designed for rapid-response observations and precision astrophysics across visible to near-infrared wavelengths (400-1700 nm bandpass). An off-axis, freeform telescope delivers diffraction-limited image quality (Strehl 0.8 at 633 nm) to three instruments across a wide, flat focal plane. The three instruments provide complementary capabilities: a Wide-field Context Camera (WCC) delivers multi-band imaging over a 35' 12' footprint with high-cadence photometry; an Integral Field Spectrograph (IFS) provides continuous 400-1700 nm spectroscopy at R 100-500 for stable spectrophotometry; and an ExtraSolar Coronagraph (ESC) enables high-contrast imaging expected to reach raw contrasts of and post-processed contrasts approaching . Operating from a 3:1 lunar-resonant orbit, Lazuli will respond to targets of opportunity in under four hours--a programmatic requirement designed to enable routine temporal responsiveness that is unprecedented for a space telescope of this size. Lazuli's technical capabilities are shaped around three broad science areas: (1) time-domain and multi-messenger astronomy, (2) stars and planets, and (3) cosmology. These capabilities enable a potent mix of science spanning gravitational wave counterpart characterization, fast-evolving transients, Type Ia supernova cosmology, high-contrast exoplanet imaging, and spectroscopy of exoplanet atmospheres. While these areas guide the observatory design, Lazuli is conceived as a general-purpose facility capable of supporting a wide range of astrophysical investigations, with open time for the global community. We describe the observatory architecture and capabilities in the preliminary design phase, with science operations anticipated following a rapid development cycle from concept to launch.
The Eric and Wendy Schmidt Observatory System is designed to pioneer a new paradigm for astronomical observatories, fundamentally rethinking how they are conceived, developed, and utilized. This initiative compresses development timelines from decades to years, dramatically lowering barriers to global participation and accelerating the pace of discovery. By uniting rapid development cycles with open data and shared scientific tools, the system empowers researchers everywhere to engage in frontier astrophysics.
