What’s Hot in Space Science

Pinpointing where the lights went out in Puerto Rico

A team of scientists from NASA’s Goddard Space Flight Center and Marshall Space Flight Center processed and corrected the raw data to filter out stray light from the Moon, fires, airglow, and any other sources that are not electric lights. Credit:

After Hurricane Maria tore across Puerto Rico, it quickly became clear that the destruction would pose daunting challenges for first responders. Using its Visible Infrared Imaging Radiometer Suite (VIIRS), NASA’s Suomi National Polar-orbiting Partnership (Suomi NPP) satellite helped first responders better deploy rescue and repair crews and to distribute life-saving supplies where there were power outages.

VIIRS created Puerto Rico’s nighttime lights based on data captured by the Suomi NPP satellite. It soon became apparent that most of the electric power grid and telecommunications network was knocked offline. Flooding, downed trees, and toppled power lines made many roads impassable.

Scientists from NASA’s Goddard Space Flight Center designed the experimental maps to make it easier to monitor neighborhood-scale outdoor features.

NASA’s Cassini spacecraft ends historic exploration of Saturn

A thrilling epoch in the exploration of our solar system came to a close last month as NASA’s Cassini spacecraft made a fatal plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet.

While the Cassini spacecraft is gone, its enormous collection of data about Saturn – the giant planet, its magnetosphere, rings and moons – will continue to yield new discoveries for decades to come.

“Cassini may be gone, but its scientific bounty will keep us occupied for many years,” said said Linda Spilker, Cassini project scientist at NASA’s Jet Propulsion Laboratory (JPL). “We’ve only scratched the surface of what we can learn from the mountain of data it has sent back over its lifetime.”

World View successfully launches near-space balloon from its new HQ

World View’s dreams of replacing satellites with edge-of-space balloons have been long in the making, and not without some hiccups. The startup has completed the first launch of a Stratollite balloon from its new headquarters in Tucson.

Right now, the balloons don’t exactly last long — World View’s longest-lasting flight was 27 hours, which would only be useful for the briefest of uses. However, the Tucson launch lays the groundwork for much more.

World View has started a new phase of refinement that could lead to balloons which stay afloat for months. That, in turn, could lead to balloons that replace satellites for long-term science experiments, weather tracking and observation.
