NASA and National Oceanic and Atmospheric Administration scientists are teaming up to test remote sensing technology for use in oil spill response.

Just off the coast of Santa Barbara, California, thousands of gallons of oil seep through cracks in the seafloor and rise to the surface each day. But this isn’t a disaster zone: It’s one of the largest naturally occurring oil seeps in the world and is believed to have been active for thousands of years.

NASA is developing capabilities that will allow missions at high altitudes to take advantage of signals from Global Navigation Satellite System (GNSS) constellations — like GPS commonly used in the U.S. These signals — used on Earth for navigation and critical timing applications — could provide NASA’s Artemis missions to the Moon with reliable timing and navigation data. NASA’s Space Communications and Navigation (SCaN) program is developing the technologies that will support this goal.
LIVERMORE, Calif. (Lawrence Livermore National Laboratory PR) — Nanosatellite technology, in particular, small cube satellites, are finding purpose in the most extraordinary places. Known as CubeSats, these miniature versions of conventional satellites can be used for applications that range from tracking space debris to monitoring atmospheric gas concentrations.
Now, Lawrence Livermore scientists and engineers are turning their expertise in CubeSat development toward assisting the U.S. Coast Guard in becoming a spacefaring agency.
EL SEGUNDO, Calif. (Aerospace Corporation PR) — For decades, the dense sea ice covering the Arctic Ocean has been shrinking and, in some regions, disappearing altogether. This environmental change is dramatically altering areas that were once blocked by ice and creating open water that is being turned into shipping lanes for an increasing number of vessels looking for a faster route between Asia, eastern North America and Europe.
According to data from the U.S. Committee On The Marine Transportation System, the number of vessels operating in the Arctic region has increased from 52 in 2008 to 144 in 2013. The committee predicts that the Arctic Ocean will see 2,111 vessels by 2025. This rapid increase in traffic through a dynamic environment like the Arctic has made U.S. Coast Guard (USCG) missions especially challenging while underscoring the need for prompt and reliable emergency distress signal response.
WASHINGTON (DHS PR) — The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) launched two miniature cube-shaped satellites (CubeSats) into space on December 3, 2018, via the SpaceX Falcon 9 rocket.
Named Yukon and Kodiak, the CubeSats, which are approximately the size of a shoebox, neatly squeezed into a 20-ft. payload stack with 62 other small satellites (SmallSats), and began orbiting our planet.
WASHINGTON (U.S. Coast Guard PR) — Two small satellites, scheduled for launch in 2018, will provide the Coast Guard with the opportunity to test the effectiveness of satellite communications in supporting Arctic search and rescue missions.
These satellites, or “cubesats,” are capable of detecting transmissions from emergency position indicating radio beacons (EPIRBs), which are carried on board vessels to broadcast their position if in distress. The Coast Guard will deploy the cubesats in cooperation with the Department of Homeland Security (DHS) Science and Technology Directorate’s Polar Scout program, the Air Force Operationally Responsive Space Office, and the National Oceanographic and Atmospheric Administration (NOAA).
