'Foreign object' found by Mars rover a rock flake,NASA
Washington, Aug 17 : A so-called "foreign object debris" spotted by Mars rover Curiosity and speculated to be a piece of spacecraft debris has turned out to be a very thin flake of rock, NASA has said.
The object in the image captured on August 13 also triggered speculation among scientists that the Curiosity rover might have shed a piece of itself.
But an analysis by Curiosity's Chemistry and Camera (ChemCam) instruments revealed that the object, which was officially referred to as "Pettegrove Point Foreign Object Debris" (PPFOD), only raised a false alarm, NASA said on Thursday.
"In fact it was found to be a very thin flake of rock, so we can all rest easy tonight - Curiosity has not begun to shed its skin," Curiosity team member Brittney Cooper wrote in a mission update of the analysis.
"Perhaps the target should have been given a different name befitting the theme of the current quadrangle in which Curiosity resides: 'Rabhadh Cearr', or 'False Alarm' in Scottish Gaelic," Cooper said.
The Curiosity team had reasons to worry as in 2012, the rover spotted an equally mysterious bright object on the surface that turned out to be a tiny piece of plastic material shed from the rover, CNET reported.
The rover is currently monitoring the dust opacity or "tau" in Gale crater as the global dust storm that started on Mars in June declines.

'Warm and engaging atmosphere reigned', Shashi Tharoor on Putin banquet
New Delhi (PTI): Senior Congress leader Shashi Tharoor, who on Friday attended a banquet for Russian President Vladimir Putin at the Rashtrapati Bhawan, on Saturday described the atmosphere there as "warm" and "engaging", and said he enjoyed his conversations with many of the attendees.
Tharoo’s remarks came a day after President Droupadi Murmu hosted a banquet for the visiting Russian president at the Rashtrapati Bhavan here.
“Attended the @rashtrapatibhvn banquet for President Putin last night. A warm and engaging atmosphere reigned. Enjoyed my conversations with many of the attendees, especially my dining companions from the Russian delegation!" Tharoor said in a social media post.
Murmu, while welcoming President Putin and his delegation at the banquet, had said that his visit marked an important milestone -- the 25th anniversary of the India-Russia strategic partnership, which was established in October 2000 during his first visit to the country as president.
Murmu also appreciated Putin's support and personal commitment to the India-Russia special and privileged strategic partnership.
The Congress on Friday said that the leaders of the opposition, Mallikarjun Kharge and Rahul Gandhi, were not invited to the banquet, and took a swipe at Tharoor for accepting the invite.
The party’s media and publicity department head, Pawan Khera, accused the government of breaking protocols daily and not believing in democratic principles.
“There is no invite to both the LoPs, Mr (Mallikarjun) Kharge and Mr (Rahul) Gandhi. This comes as a surprise, but I don't think we should be surprised. This government is known to be breaching all protocols. What else to say, ask the government,” Khera said on Friday.
Asked about Tharoor accepting the invite for the banquet, Khera said, "Ask Mr Tharoor. All of us who are in the party, if our leaders don't get invited and we get invited, we need to question our own conscience and listen to our conscience. Politics has been played in inviting or not inviting people, which in itself is questionable, and those who accept such an invite are also questionable."
“We would have listened to our voice of conscience,” he added.
Earlier, Tharoor had said that there was a time when the chairman of the external affairs committee was routinely invited, but that practice seems to have stopped some years ago.
On Thursday, Congress leader Rahul Gandhi alleged that the government tells visiting foreign dignitaries not to meet the leader of opposition due to its "insecurity".
His remarks came hours ahead of Putin's two-day visit to India.
