Curiosity Self-Portraits
It does not include the rover's robotic arm, though the shadow of the arm is visible on the ground. Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic's component images.
The arm was positioned out of the shot in the images, or portions of images, that were used in the mosaics.

Actually the robotic arm did, and as a result the shadow of the arm is in the picture, but not the arm.

It doesn't show because it is what is taking the picture. So they just edit out its part of the image. Pretty simple, actually.

Here's an article about the problem.

(26,795 posts)I'm glad the rover is still on the move. The damage was discovered over a year ago...and has been quite a concern...but it keeps on roving!

(40,416 posts)The little guy is still going strong after more than a decade. Its sister rover, Spirit, has sadly died and Opportunity is a creaky old man with some problems. Nevertheless it is still going strong enough that it keeps working every Sol (a day on Mars).
Here's the Wiki: https://en.m.wikipedia.org/wiki/Opportunity_rover
BTW, this was supposed to be a 90 day mission, ten years later still returning good science.
Nota bene: Opportunity is solar powered and small. Curiosity is huge and powered by an RTG, a radioactive thermal generator, the same thing that powers the Voyager probes which are still running after decades in space. One of them has left the solar system; the other is on its way out. We expect to remain in contact for several more years.
Curiosity is a mechanical contraption so it will not likely live that long. Just like Spirit, something will break down and put an end to the mission. Likewise Opportunity, which has some severe problems today, but keeps on trucking nevertheless.

(12,047 posts)The Juno spacecraft, currently making its way to Jupiter, will for the first time peer below Jupiter's dense cover of clouds to answer questions about the gas giant and the origins of our solar system.
Juno's primary goal is to reveal the story of Jupiter's formation and evolution. Using long-proven technologies on a spinning spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter's gravity and magnetic fields, atmospheric dynamics and composition, and evolution.
Juno will arrive at Jupiter on July 4 of this year. Over the next year the spacecraft will orbit the Jovian world 33 times, skimming to within 3,100 miles (5,000 kilometers) above the planets cloud tops every 14 days. During the flybys, Juno will probe beneath the obscuring cloud cover of Jupiter and study Jupiters aurorae to learn more about the planet's origins, structure, atmosphere and magnetosphere.
Mission Events
Launch - August 5, 2011
Deep Space Maneuvers - August/September 2012
Earth flyby gravity assist - October 2013
Jupiter arrival - July 2016
Spacecraft will orbit Jupiter for 20 months (37 orbits)
End of mission (deorbit into Jupiter) - February 2018

Should have some great pics!

(58,785 posts)if you know what I mean. It's so lovely to be drawn away like this from the small and petty and mean to a whole big world of aspiration and wonder and great accomplishment, and I'm, of course, not actually talking about Mars or Jupiter, magnificent as they are.

(12,047 posts)NASA's Juno mission to Jupiter has broken the record to become humanity's most distant solar-powered emissary. The milestone occurred at 11 a.m. PST (2 p.m. EST, 19:00 UTC) on Wednesday, Jan. 13, when Juno was about 493 million miles (793 million kilometers) from the sun.
The previous record-holder was the European Space Agency's Rosetta spacecraft, whose orbit peaked out at the 492-million-mile (792-million-kilometer) mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko.
"Juno is all about pushing the edge of technology to help us learn about our origins," said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. "We use every known technique to see through Jupiter's clouds and reveal the secrets Jupiter holds of our solar systems early history. It just seems right that the sun is helping us learn about the origin of Jupiter and the other planets that orbit it."
Launched in 2011, Juno is the first solar-powered spacecraft designed to operate at such a great distance from the sun. That's why the surface area of solar panels required to generate adequate power is quite large. The four-ton Juno spacecraft carries three 30-foot-long (9-meter) solar arrays festooned with 18,698 individual solar cells. At Earth distance from the sun, the cells have the potential to generate approximately 14 kilowatts of electricity. But transport those same rectangles of silicon and gallium arsenide to a fifth rock from the sun distance, and its a powerfully different story.

(58,785 posts)worked at JPL in the 1990s, computer support, and I miss all the chat about what they're engaged in. They were suffering the effects of severe reaganomics effects and "cut the waste" budget cuts and reorganizations in that period but were typically enthusiastically immersed in the challenges they were able to tackle anyway.
Our little 9-year-old grandsons weren't really engaged in what they'd been told about current projects in school until I told them about rogue asteroids and the AIDA project -- and that we were going to crash a probe into an asteroid's moon to try to change its orbit. Violence they could visualize! That did it, of course.
