Nasa-50-Earth-Day

This year, Nasa marks the 50th anniversary of Earth Day with a host of exciting and informative #EarthDayAtHome activities, instead of holding in-person events, due to the pandemic. This is an excellent opportunity to tune in to the slew of online broadcasts, and deepen our understanding of our planet, even as we remain indoors.

Nasa’s work in space has been helpful in understanding the risks that our home planet faces, in terms of environmental issues. For instance, the space agency has helped to document the changing climate, and created green technologies to save energy and natural resources. Their online programmes promise to be eye-opening segments in exploring important discoveries we may not have known about. On Earth Day which falls on April 22, gear up for these programmes:
