Opportunity's Science Team Remains Vigilant  

Pasadena CA (JPL) Jul 19, 2018 The dust storm on Mars is continuing as a Planet-encircling Dust Event (PEDE) with no indication of receding at this time. The storm has sustained high atmospheric opacity conditions over the Opportunity site for several weeks without any change. There is no indication at this time of the storm abating or clearing. Since the last contact with the rover on Sol 5111 (June 10, 2018), it
