Spirit Opportunity Solar Panels

No it wasn t overlooked.

Spirit opportunity solar panels.

Launched on july 7 2003 as part of nasa s mars exploration rover program it landed in meridiani planum on january 25 2004 three weeks after its twin spirit mer a touched down on the other side of the planet. Mars exploration rovers spirit and opportunity exploring the planet mars facts information videos and pictures. Both were taken by opportunity s panoramic camera pancam. Designed to last just 90 martian days and to travel 1 100 yards 1 000 meters opportunity vastly surpassed all expectations in its endurance.

The last signal from the spacecraft was heard on june 10 2018. Powered by a bank of solar cells on its upper surface each mars exploration rover mer has advanced communication capabilities that allow it to keep in touch with orbiting probes and directly with earth. Generally supposing that martian winds have blown dust clear off the probes on mars including the solar panels which power them increasing their energy output. At the end of 2008 a winter storm further reduced the output of spirit s solar panel to about 89 watt hours per martian day.

In addition the mers spirit and opportunity each carry an array of seven tools for exploring the surface of mars. The mission was required to last for 90 sols plus the landing sol about 93 earth days. Various means of cleaning the panels were discussed with wiper blades being one of the worst but all were deemed unnecessary. A cleaning event is a phenomenon whereby dust is removed from solar panels in the context of exploration and science rovers on mars supposedly by the action of wind the term cleaning event is used on several nasa webpages.

Through much of the earth summer of 2007 both spirit and opportunity faced massive dust storms that eroded their ability to operate effectively mainly due to lack of power generated from the solar panels. Opportunity also known as mer b mars exploration rover b or mer 1 and nicknamed oppy is a robotic rover that was active on mars from 2004 until the middle of 2018. 1 start with a solar energy franchise or as a sole proprietor. A self portrait of nasa s mars exploration rover opportunity taken in late march 2014 right shows that much of the dust on the rover s solar arrays has been removed since a similar portrait from january 2014 left.

Sister rover spirit was not able to soldier on for as long as opportunity but it wasn t dust covering its solar panels that killed. New entrepreneurs have many important decisions to make but one of the biggest is whether to start a business of their own creation as a sole proprietor or to own a proven solar energy franchise system.
