a new US-Chilean facility located in Chile
a joint project of NSF & DOE operates under NOIRlab
Operations start late 2023
what's in a name?
The first ground-based national US observatory named after a woman, Dr. Vera C. Rubin
VRO
In the first 10 years of its life Rubin will conduct the Legacy Survey of Space and Time or LSST

Exquisite image quality
all over the sky
over and over again
SDSS image circa 2000
HSC image circa 2018
when you look at the sky at this resolution and this depth...
everything is blended and everything is changing
world public!
Rubin LSST will deliver 10M alerts each night about anything that changed in the southern hemisphere sky: supernovae, merging stars, transiting planets, gravity bendind light and magnifying stars...
to anyone in the world by a set of selected "brokers" that will work with Rubin to accomplish this incredible goal!
the data belongs to the people!
within 60 second of detection!

Rubin LSST = Astro + DataScience
Rubin will see ~1000 SN every night!
A lot of them will be too faint to study with traditional means, particularly spectra.
Lots of emphasis in new analysis techniques that rely on "Big Data"

LIGO/VIRGO area of localization ~100deg square
Ursa Minor contains 255.86 square degrees
S190425z 18% of the sky localization
Rubin can find the electromagnetic counterpart of Gravitational Wave and Neutrino discoveries better than any survey!

6 teams (One-Meter, Two Hemispheres (1M2H), DLT40, VISTA, Master, DECam, Las Cumbres Observatory imaged the same new source independently in a 90-minute interval. The first to detect optical light associated with the collision was the 1M2H team running the Swope Supernova Survey, which found it in an image of NGC 4993 taken 10 hours and 52 minutes after the GW event by the 1-meter diameter (3.3 ft) Swope Telescope operating in the near infrared at Las Campanas Observatory, Chile. They were also the first to announce it, naming their detection SSS 17a in a circular issued 12h26m post-event. The new source was later given an official International Astronomical Union (IAU) designation of AT 2017gfo.

Evidence that mergers of NS are significant sources of r-process elements heavier than iron, including gold and platinum, which was previously attributed exclusively to supernova explosions

think about us as an army of volunteers that thinks Rubin LSST will be amazing and transformational and are investing in preparing to use its data and helping optimize the Observatory choices

We aspire to be an inclusive, equitable, and ultimately just group and we are working with renewed vigor in the wake of the recent event that exposed inequity and racism in our society to turning this aspiration into action.
