The latest picture was taken by the rover at "Buckskin", which is the seventh rock target on its mission.
Curiosity does this planetary photography in the same way we would take a selfie - by holding a camera at arm's length and framing itself.
The pictures must then be stitched together to make this final scene.
Nasa is trying to take one at every location where the robot drills into the surface of the red planet.
The robot has now been on Mars for three Earth years.  It is in what's known as Gale Crater.
Curiosity is currently climbing through what's known as Mount Sharp, examining the rocks as it goes.
Scientists want to understand when and how Mars became so barren.

The £15,000 prize was presented to London-born Orr by Woman's Hour's Dame Jenni Murray at a ceremony in London.
Author and judge Kei Miller described Disappearances as "a near perfect example of how the short story works".
The story about guilt and identity was inspired by Orr watching a solitary man in a cafe while in Argentina.
It tells the tale of a retired plastic surgeon who develops a relationship with a local waitress.
The shortlist for the competition was made up of five women.
Runner-up Claire-Louise Bennett, also a debut writer, received £3,000 in prize money for her story Morning, Noon & Night.
The other three shortlisted authors, Mantel, Lavinia Greenlaw and Tahmima Anam, each received £500.
Di Speirs, books editor at BBC Radio 4, which broadcasts the event, said: "In a year when the shortlist was supremely well balanced and the judges initially quite divided about a winner, our meeting was full of insight, debate, discussion and courtesy; by its conclusion we were all of a mind.
"KJ Orr's precision and clarity, her ability to expose a life in a line and to induce sympathy and disdain, linger long after reading the final paragraph."
Orr's debut collection of short stories, Light Box, was published in February.
Her stories have appeared in the Sunday Times Magazine, The Irish Times and The Dublin Review amongst others and she was shortlisted for the BBC National Short Story Award for the first time in 2011.
Orr studied at St. Andrews, UEA and Chichester and has published essays and reviews in Poetry Review, the TLS and the Guardian.
Previous winners of the BBC National Short Story prize include Jonathan Buckley, Julian Gough, James Lasdun, Lionel Shriver and Clare Wigfall.

Matthew Cherrington, 32, from West Bromwich, murdered 26-year-old sex worker Lidia Pascale, who was last seen on 19 November 2014.
Her body was discovered more than two weeks later in Hope Street, West Bromwich.
Cherrington must serve a minimum of 19 years, Birmingham Crown Court was told.
The electrician arranged for Ms Pascale, who had been working as an escort, to visit his flat where he attacked and killed her, West Midlands Crown Prosecution Service (CPS) said.
Ms Pascale, who had been staying in Smethwick, West Midlands, and Coventry, had suffered at least 11 blows to the head.
Judge Melbourne Inman told Cherrington he was "a very dangerous man capable of extreme unprovoked violence" who had "never shown any remorse or regret."
The CPS said Cherrington, of High Street, tried to "evade detection" and had blamed an associate for Ms Pascale's disappearance.
Mobile phone analysis showed he had contacted several escorts including Ms Pascale on the day of the murder, the CPS said.
Emily Lenham, from the CPS, said: "A very dangerous man has been convicted of a brutal and senseless crime."
A West Midlands Police spokesperson said the force was supporting Ms Pascale's family, who are from Tulcea in Romania.
The US space agency Nasa has issued a "selfie" portrait from its Curiosity rover on Mars.
