Early in the pandemic, it was expected that satellite imagery around the world would show cleaner air as a result of COVID-19 lockdowns. But not all pollutants were taken out of circulation. For tiny airborne-particle pollution, known as PM 2.5, researchers using NASA data found that variability from meteorology obscured the lockdown signals when observed from space.

Using data originally gathered for spacecraft ‘housekeeping’ aboard ESA’s Rosetta and Mars Express missions, scientists have revealed how intense bursts of high-energy radiation, known as cosmic rays, behave at Mars and throughout the inner Solar System.
NASA team to study new roles for the agency in addressing orbital debris
Monday, 28 June 2021 01:15
WASHINGTON — NASA has established a working group to examine what new roles the agency can take to mitigate the growth of orbital debris and promote space sustainability.
In a talk at the Secure World Foundation’s Summit for Space Sustainability June 23, Bhavya Lal, senior adviser to the NASA administrator for budget and finance, said she is leading a recently established team that will examine how the agency could take a larger role in efforts to mitigate and remediate orbital debris.
