An international team of researchers came up with a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment, and it may deliver high rates of molecule production per kilogram of instrumentation sent to space.

Such a system could play a critical role in the development of life-support systems on Mars and the feedstock and base chemicals necessary for processing fuels, building materials, and fertilizers.

In the Journal of Applied Physics, the team from the University of Lisbon, the Massachusetts Institute of Technology, Sorbonne University, Eindhoven University of Technology, and the Dutch Institute for Fundamental Energy Research presented a method for harnessing and processing local resources to generate products on Mars.

Satellites owned by private companies have played an unexpectedly important role in the war in Ukraine. For example, in early August 2022, images from the private satellite company Planet Labs showed that a recent attack on a Russian military base in Crimea caused more damage than Russia had suggested in public reports. Ukrainian President Volodymyr Zelenskyy highlighted the losses as evidence of Ukraine's progress in the war.

Soon after the war began, Ukraine requested data from private satellite companies around the world. By the end of April, Ukraine was getting imagery from U.S. companies mere minutes after the data was collected.

My research focuses on international cooperation in satellite Earth observations, including the role of the private sector.

The core of NASA's Europa Clipper spacecraft has taken center stage in the Spacecraft Assembly Facility at the agency's Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) wide, the craft's main body will for the next two years be the focus of attention in the facility's ultra-hygienic High Bay 1 as engineers and technicians assemble the spacecraft for its launch to Jupiter's moon Europa in October 2024.

Scientists believe the ice-enveloped moon harbors a vast internal ocean that may have conditions suitable for supporting life. During nearly 50 flybys of Europa, the spacecraft's suite of science instruments will gather data on the moon's atmosphere, surface, and interior—information that scientists will use to gauge the depth and salinity of the ocean, the thickness of the ice crust, and potential plumes that may be venting subsurface water into space.
