NASA’s Perseverance rover, which successfully landed on Mars on February 18, is powered in part by the first plutonium produced at Department of Energy laboratories in more than 30 years. The radioactive decay of Pu-238 provides heat to radioisotope thermoelectric generators (RTGs) like the one onboard Perseverance and would also be used by the Dynamic Radioisotope Power System, currently under development, which is expected to provide three times the power of RTGs.
Idaho National Laboratory is scaling up the production of Pu-238 to help meet NASA’s production goal of 1.5 kg per year by 2026, the DOE announced on February 17.




The Environmental Protection Agency has awarded three contracts for cleanup efforts at more than 50 abandoned uranium mine sites in and around the Navajo Nation in the southwestern United States. The Navaho Area Abandoned Mine Remedial Construction and Services Contracts, worth up to $220 million over the next five years, were awarded to the Red Rock Remediation Joint Venture, Environmental Quality Management, and Arrowhead Contracting, the agency announced on February 11.
Maybe everything really is bigger in Texas, but that’s not necessarily a good thing. The brutal winter storm that hit much of the country earlier this week struck the Lone Star State with particular severity, leaving the power grid in shambles and millions of Texas residents without power, in many instances for days. On Tuesday, at the height of the power crisis, more than 4.4 million utility customers were without access to electricity, according to 
Coordinated federal and private industry investments made now could yield an operational fusion pilot plant in the 2035–2040 time frame, according to
