SPOC Satellite to be deployed into orbit from the ISS
After having been on the International Space Station a couple weeks, SPOC is scheduled to be deployed into orbit on November 5th at 4:05 AM ET, where the satellite begins it's research mission monitoring the health of coastal ecosystems using an advanced optic system that can zoom in on coastal areas to detect chemical composition and physical characteristics on ocean and wetland surfaces.

The Hubble Space Telescope: 30 Years of Cosmic Discovery
The Hubble Space Telescope is operating at peak scientific capability even 30 years after its launch, thanks to successful astronaut servicing missions and operations that keep the observatory in top condition. I will review the premiere scientific advancements achieved by Hubble, including both those that were planned at launch (e.g. measuring the Hubble constant) and many that were never dreamed of at launch (e.g. finding evidence for dark energy; analyzing exoplanet atmospheres). Hubble and ground-based observations together led to the discovery of the accelerating expansion of the universe and a resulting Nobel Prize. Hubble observations are now driving new quests in Multi-Messenger Astronomy and in revealing fundamental discrepancies in cosmological measurements. Hubble programs are also preparing the field for JWST, the Roman Space Telescope, and other future missions, and are contributing critical data in coordination with ground-based observatories and solar system probes like JUNO. I will discuss how Hubble can be used in its coming final years to provide the best science return, complementing other space-based and ground-based observatories and setting the stage for future breakthroughs in astrophysics.

Quantum Turbulent Structure in Light
A random superposition of plane waves is known to be threaded with vortex line singularities which form complicated tangles and obey strict topological rules. In this work, we use both numerical simulations of random waves and experiments on laser speckle to observe and characterize the dynamics of the vortex tangles. We find that the velocity statistics of the vortices in random waves match those of turbulent quantum fluids such as superfluid helium and atomic Bose- Einstein condensates (Physical Review Letters 122, 044301 2019). These statistics are shown to be independent of system scale. These results raise deep questions about the role of nonlinearity in the structure of turbulence and the general nature of quantum chaos.
