Emission Reductions From Pandemic Had Unexpected Effects on Atmosphere

Earth’s atmosphere reacted in surprising ways to the lowering of emissions during the pandemic, showing how closely climate warming and air pollution are linked.

PASADENA, Calif. (NASA PR) — The COVID-19 pandemic and resulting limitations on travel and other economic sectors by countries around the globe drastically decreased air pollution and greenhouse gas emissions within just a few weeks. That sudden change gave scientists an unprecedented view of results that would take regulations years to achieve.

Report: NASA Needs to Improve Oversight of Contracts and Grants

NASA finished assembling the main structural components for the Space Launch System (SLS) rocket core stage on Sept. 19. Engineers at NASA’s Michoud Assembly Facility in New Orleans fully integrated the last piece of the 212-foot-tall core stage by adding the engine section to the rest of the previously assembled structure. Boeing technicians bolted the engine section to the stage’s liquid hydrogen propellant tank. (Credit: NASA/Steven Seipel)

Between 2014 and 2017, NASA awarded Boeing a total of $64 million in performance awards for its work on the Space Launch System (SLS) despite significant schedule delays and cost overruns in the program.

It was only after the NASA Office of Inspector General (OIG) questioned the propriety of the awards that SLS program officials began “providing Boeing award fees that better reflected actual performance,” the space agency’s watchdog said in a new report.
