The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope image is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms, and bright blue star clusters. Also captured in the upper left-hand corner is a far closer object: a star just 577 light-years away in our own galaxy.
UGC 5460 has hosted two recent supernovae: SN 2011ht and SN 2015as. It’s because of these two stellar explosions that Hubble targeted this galaxy, collecting data for three observing programs that aim to study various kinds of supernovae.
SN 2015as was as a core-collapse supernova: a cataclysmic explosion that happens when the core of a star far more massive than the Sun runs out of fuel and collapses under its own gravity, initiating a rebound of material outside the core. Hubble observations of SN 2015as will help researchers understand what happens when the expanding shockwave of a supernova collides with the gas that surrounds the exploded star.
SN 2011ht might have been a core-collapse supernova as well, but it could also be an impostor called a luminous blue variable. Luminous blue variables are rare stars that experience eruptions so large that they can mimic supernovae. Crucially, luminous blue variables emerge from these eruptions unscathed, while stars that go supernova do not. Hubble will search for a stellar survivor at SN 2011ht’s location with the goal of revealing the explosion’s origin.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
How to Attend
The workshop will be hosted by NASA Jet Propulsion Laboratory.
Virtual and in-person attendance are available. Registration is required for both. (Link coming soon!)
Virtual attendees will receive connection information one week before the workshop.
Background, Goals and Objectives
The NASA Engineering and Safety Center (NESC) is conducting an assessment of the state of cold capable electronics for future lunar surface missions. The intent is to enable the continuous use of electronics with minimal or no thermal management on missions of up to 20 years in all regions of the lunar surface, e.g., permanently shadowed regions and equatorial. The scope of the assessment includes: capture of the state of cold electronics at NASA, academia, and industry; applications and challenges for lunar environments; gap analyses of desired capabilities vs state of the art/practice; guidance for cold electronics selection, evaluation and qualification; and recommendations for technology advances and follow-on actions to close the gaps. The preliminary report of the assessment will be available the first week of April 2025 on this website, i.e., 3 weeks prior to the workshop. Attendees are urged to read the report beforehand as the workshop will provide only a limited, high-level summary of the report’s key findings. The goal of the workshop is to capture your feedback with regards to the findings of the report, especially in the areas below: Technologies, new or important studies or data that we missed. Gaps, i.e. requirements vs available capabilities that we missed. Additional recommendations, suggestions, requests, that we missed.

Electrical engineer Scott Hesh works on a sub-payload canister at NASA’s Wallops Flight Facility near Chincoteague, Virginia. The cannister will be part of a science experiment and a demonstration of his Swarm Communications technology.Credits: NASA’s Wallops Flight Facility/Berit Bland Scott Hesh, an electrical engineer at NASA’s Wallops Flight Facility on Virginia’s Eastern Shore, was announced Nov. 2 as the FY22 IRAD Innovator of the Year, an award presented by the agency’s Goddard Space Flight Center in Greenbelt, Maryland.
“An electrical engineer with an insatiable curiosity, Scott Hesh and his team have worked hand-in-glove with science investigators since 2017,” said Goddard Chief Technologist Peter Hughes. “He developed a technology to sample Earth’s upper atmosphere in multiple dimensions with more accurate time and location data than previously possible with a sounding rocket.”

“Scott has this enthusiasm for what he does that I think is really contagious,” Sounding Rocket Program technologist Cathy Hesh said. “He’s an electrical engineer by education, but he has such a grasp on other disciplines as well, so he’s sort of like a systems engineer. If he wants to improve something, he just goes out and learns all sorts of things that would be beyond the scope of his discipline.”
Mechanical engineer Josh Yacobucci has worked with Scott Hesh for more than 15 years, and said he always learns something when they collaborate.
“Scott brings this great perspective,” Yacobucci said. “He could help winnow out things in my designs that I hadn’t thought of.”
“For his interdisciplinary leadership resulting in game-changing improvements for atmospheric and solar science capabilities,” Hughes said, “Scott Hesh deserves Goddard’s Innovator of the Year Award.”

Dr. Dorothy M. Peteet is a senior research scientist at GISS and an adjunct professor at Columbia University. She directs the Paleoecology Division of the New Core Lab at Lamont Doherty Earth Observatory (LDEO) of Columbia.
In collaboration with GISS climate modelers and LDEO geochemists, she is studying conditions of the Late Pleistocene and Holocene that are archived in sediments from lakes and wetlands. Peteet documents past changes in vegetation, derived from analyses of pollen and spores, plant and animal macrofossils, carbon, and charcoal embedded in sediments. Her research provides local and regional records of ancient vegetational and climate history. One recent focus has been the sequestration of carbon in northern peatlands and coastal marshes: ecosystems that are now vulnerable to climate change and potentially substantial releases of carbon back into the atmosphere.
Peteet also has performed climate modeling experiments to test hypotheses concerning the last glacial maximum and abrupt climate change. She is interested in climate sensitivity and in how past climate changes and ecological shifts might provide insights on future climate change.
