Search for iron-containing minerals, and to identify and quantify relative amounts of specific mineral types that contain water or were formed in water, such as iron-bearing carbonates.This will help determine the accuracy and effectiveness of various instruments that survey Martian geology from orbit. Perform calibration and validation of surface observations made by Mars Reconnaissance Orbiter (MRO) instruments.Such processes could include water or wind erosion, sedimentation, hydrothermal mechanisms, volcanism, and cratering. Determine what geologic processes have shaped the local terrain and influenced the chemistry.Determine the distribution and composition of minerals, rocks, and soils surrounding the landing sites.In particular, samples sought include those that have minerals deposited by water-related processes such as precipitation, evaporation, sedimentary cementation, or hydrothermal activity. Search for and characterize a variety of rocks and soils that hold clues to past water activity.The scientific objectives of the Mars Exploration Rover mission were to: On February 13, 2019, NASA officials declared that the Opportunity mission was complete, after the spacecraft had failed to respond to over 1,000 signals sent since August 2018. NASA hoped to re-establish contact with the rover, citing a recurring windy period which was forecast for November 2018 to January 2019, that could potentially clean off its solar panels. It was hoped it would reboot once the weather cleared, but it did not, suggesting either a catastrophic failure or that a layer of dust had covered its solar panels. ĭue to the planetary 2018 dust storm on Mars, Opportunity ceased communications on June 10 and entered hibernation on June 12, 2018. The rover survived moderate dust storms and in 2011 reached Endeavour crater, which has been considered as a "second landing site." The Opportunity mission is considered one of NASA's most successful ventures. Mission highlights included the initial 90-sol mission, finding meteorites such as Heat Shield Rock (Meridiani Planum meteorite), and over two years of exploring and studying Victoria crater. By June 10, 2018, when it last contacted NASA, the rover had traveled a distance of 45.16 kilometers (28.06 miles). This careful operation allowed Opportunity to operate for 57 times its designed lifespan, exceeding the initial plan by 14 years, 47 days (in Earth time). With a planned 90- sol duration of activity (slightly less than 92.5 Earth days), Spirit functioned until it got stuck in 2009 and ceased communications in 2010, while Opportunity was able to stay operational for 5111 sols after landing, maintaining its power and key systems through continual recharging of its batteries using solar power, and hibernating during events such as dust storms to save power. 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. Opportunity was operational on Mars for 5111 sols (14 years, 138 days on Earth). Go to Filter > Noise > Add Noise and add a small amount of noise with a Gaussian Distribution and Monochromatic ticked.Īdding a dust overlay in Photoshop is a great way to give your photos an aged look.Opportunity, also known as MER-B ( Mars Exploration Rover – B) or MER-1, is a robotic rover that was active on Mars from 2004 until 2018. A lower opacity will make the dust more subtle, while a higher opacity will make it more pronounced.ĥ. Adjust the opacity of the dust layer until you’re happy with the look. This will allow the black background of the dust layer to become transparent, making it look like it’s part of the image itself.Ĥ. Change the blending mode of the dust layer to Screen. Return to the image you’re working on, make sure the new layer is active, and press CTRL+V to paste.ģ. To do this, open the image containing the dust overlay in Photoshop and press CTRL+A to select all, then CTRL+C to copy. Paste the dust overlay onto the new layer. Create a new layer by clicking on the “Create a new layer” icon at the bottom of the Layers panel.Ģ. Open the image you want to add the dust overlay to in Photoshop. It’s also a quick and easy way to add some interest to otherwise bland images. Adding a dust overlay in Photoshop is a great way to give your photos an aged look.
