U.S. National Science Foundation award funds Skynet's build-out

What the award funds

The U.S. National Science Foundation (NSF) has awarded $874,000 through its Advanced Technologies and Instrumentation program to complete Skynet 2 — the platform behind this site. The work falls into four areas:

• Deployment and hardening. Moving from a working testbed to software that runs unattended, at every participating site, every clear night.
• Telescope onboarding. Bringing committed facilities onto the network in sequenced waves, beginning with experienced operators who have time to help shake the system out.
• Event-broker integration. Connecting Skynet to the time-domain brokers — ALeRCE, Fink, Lasair, and ANTARES — so that survey alerts can trigger follow-up without a human in the loop.
• New observing modes. Extending the range of observations the network can plan and execute automatically, across both optical and radio facilities.

This follows a $3M Department of Defense National Defense Education Program award that funded four years of design and construction on the baseline Skynet 2 system.

Why a constellation

Time-domain astronomy is entering an age of overabundance. The Zwicky Transient Facility already produces on the order of a million alerts per night, and Vera C. Rubin Observatory, the Argus Array, and the Deep Synoptic Array will expand the number, cadence, and wavelength coverage of transient discoveries by a further order of magnitude.

Detection is no longer the bottleneck. Characterization is. Brokers can filter and preliminarily classify these streams computationally, but the rarest and most valuable events need something a survey cannot provide on its own: dense, targeted observations that begin immediately and continue across hours, days, wavelengths, and longitudes. Even the largest telescope networks operating today could do that for only the brightest few thousand events a year. Doing it at the scale the new surveys demand takes not tens of telescopes, but hundreds.

The same limit applies in education. Between one and two percent of survey-level undergraduate astronomy students in the United States now use professional telescopes as part of their coursework, and that is close to the ceiling of what Skynet's original two dozen telescopes can support alongside their research obligations.

A different model

Most telescope networks are collections of similar hardware bought and maintained by a single organization. That model cannot grow without proportional capital and staffing.

Skynet 2 federates instead. One to two orders of magnitude more professional-quality telescopes have already been deployed by colleges and universities, regional astronomy organizations, private individuals, national observatories, and space-situational-awareness companies — and most are significantly underused.

Participation is reciprocal and deliberately light. Owners keep local control of their telescopes and contribute a fraction of contested time to constellation-wide programs — generally around 10% for sub-meter optical and smaller radio facilities, negotiated downward for larger apertures. Otherwise-idle time can still be used without drawing down that allocation. In return, participants gain access to the much larger global pool and can join science and education programs that no single facility could support.

Where things stand

More than 100 telescopes have committed to the network, optical and radio, spanning six continents and ten countries. Optical apertures range from 8 inches to 2.4 metres; radio facilities range from 2 to 40 metres.

Those telescopes are committed, not yet connected. Onboarding runs in waves through 2029, and this platform is open now so that participating operators, and anyone who wants to see where the project is going, can use it while it is being built. Much of what you can exercise here today runs against simulated hardware, and some features are still limited or disabled. That is what a build-out looks like from the inside.

What comes next

As facilities come online, a constellation-wide science working group will feed multi-wavelength light curves into the downstream brokers and follow up high-priority, broker-flagged events. Campaigns should be able to draw on scores — and eventually perhaps hundreds — of telescopes at once, producing densely sampled, time-resolved, multi-wavelength coverage. Through the AEON+ partnership, especially compelling targets can also be coordinated with 4–8 metre facilities.

On the education side, Skynet's established OPIS! curriculum continues, joined by the more advanced MWU! curriculum in which students work with both professional optical and professional radio telescopes. At more than 100 telescopes, the network has the capacity to roughly quadruple Skynet's educational reach, and to keep scaling as more owners adopt the platform.

Skynet has operated computer-controlled telescopes for more than two decades, supporting research that has produced roughly one refereed paper every 24 days, including five in Nature and Science. Skynet 2 is how that continues at the scale the next decade of surveys will require.
