EPIC maintains a constant view of the fully illuminated Earth as it rotates, providing scientific observations of ozone, vegetation, cloud height and aerosols in the atmosphere. Once EPIC begins regular observations next month, the camera will provide a series of Earth images allowing study of daily variations over the entire globe. About twice a year the camera will capture the moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the moon.
These images were taken between 3:50 p.m. and 8:45 p.m. EDT on July 16, showing the moon moving over the Pacific Ocean near North America. The North Pole is in the upper left corner of the image. It is in the original orientation as taken by the spacecraft.
The far side of the moon was not seen until 1959 when the Soviet Luna 3 spacecraft returned the first images. Since then, several NASA missions have imaged the lunar far side in great detail. The same side of the moon always faces an earthbound observer because the moon is tidally locked to Earth. That means its orbital period is the same as its rotation around its axis.
Combining three images taken about 30 seconds apart as the moon moves produces a slight but noticeable camera artifact on the right side of the moon. Because the moon has moved in relation to the Earth between the time the first (red) and last (green) exposures were made, a thin green offset appears on the right side of the moon when the three exposures are combined. This natural lunar movement also produces a slight red and blue offset on the left side of the moon in these unaltered images.
The lunar far side lacks the large, dark, basaltic plains, or maria, that are so prominent on the Earth-facing side. The largest far side features are Mare Moscoviense in the upper left and Tsiolkovskiy crater in the lower left. A thin sliver of shadowed area of moon is visible on its right side.
Once EPIC begins regular observations next month, NASA will post daily color images of Earth to a dedicated public website. These images, showing different views of the planet as it rotates through the day, will be available 12 to 36 hours after they are acquired.
A full moon occurs when the moon is on the opposite side of Earth from the sun. It officially reached full illumination at 6:17 a.m. EDT (1017 GMT) on July 21 but still appears relatively full for a few days around the peak.
The July full moon is also known as the Buck Moon or the Thunder Moon, the former because it coincides with the time of year when male deer antlers are in full growth and the latter because it is also when thunderstorms are common in many parts of the world.
Another stunning entry from Turkey shows the Buck Moon setting in the early hours at Anitkabir, a mausoleum complex in the ankaya district of Ankara. The mausoleum serves as the resting place of Mustafa Kemal Atatrk, the first president of the Turkish Republic.

My rules for moon photography are simple: capture detail in both the moon and the landscape in one click (no blending of images for exposure, or to upsize or reposition the moon), and appreciate the moment.
I enjoy using the moon as a simple accent to a wide angle scene, but when possible, I also try to photograph the moon big, the bigger the better. And each time I do capture a big moon, I try to figure out how I might capture it even bigger the next time.
Of course increasing the focal length to increase the size of your moon decreases the field of view correspondingly. One of the most difficult parts of pairing a large moon with a specific landscape subject is finding a vantage point distant enough to fit the terrestrial subject and the moon. For example, there are some great views of Half Dome on the east side of Yosemite Valley, but the longest focal length I can use there and still fit all of Half Dome is around 150mm.
Coordinating all the moving parts (moon phase and position, foreground subject alignment, subject distance, and rise/set timing) requires a little advance work. Once I choose a subject to go with my moon, I try to find the most distant view of that subject. Then I need to figure out when that location, my distant subject, and the moon all align.
With a terrestrial subject identified, I do my plotting and mark my calendar for the day I want to be there. That often means waiting a year or more for the alignment I want. The location I monitor most closely for a possible full moon alignment is Yosemite, which has a wealth of prominent subjects and distant vistas.
This image was intercepted by the Jodrell Bank observatory in England, which beat the Soviets to releasing it. The quality in this version was less than ideal, but it was the one that made the newspapers like my hometown Calgary Herald.
This image, along with data transmitted from strain gauges in the three landing legs, gave valuable information to NASA about the bearing strength of the lunar surface, vital for planning the Apollo missions that were to follow.
Surveyor 1 shut down during the 14-day lunar night but revived and transmitted pictures until July 14. Even after that it was able to send back engineering data during lunar days until January 1967. Its panoramas have been processed more recently by Philip J. Stooke of the University of Western Ontario.
Those were exciting days for space enthusiasts and for the general public. We were witnessing the first pictures taken from the surface of another world. That same summer, spacecraft also went into orbit around the Moon for the first time. Luna 10 and Lunar Orbiter 1 transmitted many more images, as did their successors. Three years later, humans walked on the Moon, helped in no small part by their robotic precursors.
The images reveal surface features as small as 50 miles across, a spatial resolution that until now had been achievable only with spacecraft sent to Jupiter, such as the two Voyager spacecraft in 1979, the Galileo mission, which ended in 2003, and Juno, which has been orbiting Jupiter since 2016. The resolution is equivalent to taking a picture of a dime-sized object from 100 miles away, according to the research team. The images are two to three times better than could be obtained through the Hubble Space Telescope.
Her hope is to combine optical images from the LBT with infrared observations to correlate glowing hot magma with visible features, such as lava flows and colorful deposits created by fallout from volcanic plumes.
The Moon landing was one of the biggest television events in history, reaching an estimated 650 million viewers. This incredible milestone in broadcasting was the result of years of planning and technological development.
The image and sound signals were transmitted via a lightweight antenna on the top of the lander. The umbrella-like antenna was lined with 38 miles of fine gold-plated wire, thinner than human hair, to reflect the signal 250,000 miles back to Earth.
Goldstone Observatory in California was also receiving the signal, but the picture was grainy and hard to make out. At the last second, NASA switched from Goldstone to Honeysuckle for the world broadcast. The Parkes radio telescope dish in Australia also began transmitting once it was able to have line-of-sight contact with Apollo 11.
At first, the images broadcast from the Moon were upside down, due to the position in which the television camera had been mounted on the Lunar Module for safe transport. Operators at Honeysuckle Creek flipped the picture for broadcast; when the astronauts moved the camera to a tripod, it was flipped back around.
Many broadcasters used simulations to flesh out their Apollo programming. Networks paid hundreds of thousands of dollars for scale models of Apollo command modules and rockets. During the broadcast, these were used to create simulations of the mission which were then intercut with real footage.
The High Resolution Imaging Science Experiment (HiRISE) camera would make a great backyard telescope for viewing Mars, and we can also use it at Mars to view other planets. This is an image of Earth and the moon, acquired on October 3, 2007, by the HiRISE camera on NASA's Mars Reconnaissance Orbiter.
