Farside Northern Highlands
Window to the Farside Mantle
Farside! And All the Way Around
In a clean room at NASA's Jet Propulsion Laboratory in Southern California in March 2024, technician Nik Schwarz prepares the agency's Farside Seismic Suite (FSS) for testing. The cube-shaped payload contains two instruments that will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation (the shiny, reflective material seen here) and suspended within an outer protective cube, which is in turn covered with a shiny insulating blanket. A technician is here attaching a stiffening brace to the bottom of the FSS outer cube structure. https://photojournal.jpl.nasa.gov/catalog/PIA26341
In a clean room at NASA's Jet Propulsion Laboratory in Southern California in March 2024, engineers and technicians work to prepare the agency's Farside Seismic Suite (FSS) for environmental testing to simulate conditions it will encounter in space. Along with being placed in a vacuum chamber and subjected to extreme temperatures, the instrument suite will undergo severe shaking that mimics the rocket's motion during launch. The cube-shaped payload contains two instruments that will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation and suspended within an outer protective cube, which is in turn covered with a shiny insulating blanket. The suite's single solar panel can be seen at center. On top is a white radiator that will allow the suite to shed heat generated by its electronics during the hot lunar daytime hours. The puck-like object atop the radiator is the suite's antenna, for communicating with two small relay satellites that will orbit the Moon and send data to Earth.

Here, engineers move FSS onto a fixture that will allow them to tilt the payload, simulating the pull of lunar gravity in the direction at which one of the instrument's two seismometers is sensitive to motion. (The Moon's gravity is about one-sixth of Earth's.) Called an ambient tilt test, this activity allows engineers to check the seismometers' performance. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation and suspended within an outer protective cube, which is in turn covered with a shiny insulating blanket. The suite's single solar panel can be seen right of center.

NASA's Farside Seismic Suite (FSS) is assembled in a clean room at the agency's Jet Propulsion Laboratory in Southern California in November 2023. Two sensitive seismometers packaged in the suite's cube-within-a-cube structure will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. Seen here is the inner cube structure, with the suite's large battery at rear. The gold, puck-shaped device at left is the Short Period sensor, or SP, which measures motion in three directions using sensors etched into a trio of square silicon chips, each about 1 inch (25 millimeters) wide. At right, within the silver cylindrical enclosure, is the Very Broadband seismometer, or VBB, the most sensitive seismometer ever built for use in space exploration. It can detect ground motions smaller than the size of a single hydrogen atom, measuring up-and-down movement using a pendulum held in place by a spring. Constructed as a backup instrument (a "flight spare") for NASA's InSight Mars lander by the French space agency, CNES (Centre National d'Études Spatiales), the VBB was slightly modified and packaged in a new enclosure for lunar use. The suite's computer and electronics are packed alongside the battery and seismometers. After being encased in insulation, this inner cube was suspended within a protective outer cube, which was in turn covered with a shiny insulating blanket. https://photojournal.jpl.nasa.gov/catalog/PIA26300
There's no way to tell from this SOHO image whether the halo CME on March 5, 2013, originated from the front or far of the sun. But the STEREO spacecraft were watching the sun from the sides and showed it was from the far side. The bright planet is Venus. Credit: NASA/SOHO CME WEEK: What To See in CME Images Two main types of explosions occur on the sun: solar flares and coronal mass ejections. Unlike the energy and x-rays produced in a solar flare – which can reach Earth at the speed of light in eight minutes – coronal mass ejections are giant, expanding clouds of solar material that take one to three days to reach Earth. Once at Earth, these ejections, also called CMEs, can impact satellites in space or interfere with radio communications. During CME WEEK from Sept. 22 to 26, 2014, we explore different aspects of these giant eruptions that surge out from the star we live with. When a coronal mass ejection blasts off the sun, scientists rely on instruments called coronagraphs to track their progress. Coronagraphs block out the bright light of the sun, so that the much fainter material in the solar atmosphere -- including CMEs -- can be seen in the surrounding space. CMEs appear in these images as expanding shells of material from the sun's atmosphere -- sometimes a core of colder, solar material (called a filament) from near the sun's surface moves in the center. But mapping out such three-dimensional components from a two-dimensional image isn't easy. Watch the slideshow to find out how scientists interpret what they see in CME pictures. The images in the slideshow are from the three sets of coronagraphs NASA currently has in space. One is on the joint European Space Agency and NASA Solar and Heliospheric Observatory, or SOHO. SOHO launched in 1995, and sits between Earth and the sun about a million miles away from Earth. The other two coronagraphs are on the two spacecraft of the NASA Solar Terrestrial Relations Observatory, or STEREO, mission, which launched in 2006. The two STEREO spacecraft are both currently viewing the far side of the sun. Together these instruments help scientists create a three-dimensional model of any CME as its journey unfolds through interplanetary space. Such information can show why a given characteristic of a CME close to the sun might lead to a given effect near Earth, or any other planet in the solar system...<b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b> <b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

About 50,000 Clementine images were processed to produce the four orthographic views of the Moon. The images show albedo variations (normalized brightness or reflectivity) of the surface at a wavelength of 750 nm (just longward of visible red). The image projection is centered at 0 degree latitude and 180 degrees longitude. Mare Moscoviense (dark albedo feature upper left of image center) and South Pole-Aitken Basin (dark feature at bottom) represent maria regions largely absent on the lunar farside. The Clementine altimeter showed Aitken Basin to consist of a topographic rim about 2500 km in diameter, an inner shelf ranging from 400 to 600 km in width, and an irregular depressed floor about 12 km in depth. http://photojournal.jpl.nasa.gov/catalog/PIA00304
AS08-13-2327 (21-27 Dec. 1968) --- A brightly-rayed crater on the farside of the moon near the sub solar point, where the sun was directly overhead, as seen from the Apollo 8 spacecraft. (HOLD PICTURE WITH THE CRATER SLIGHTLY TO THE UPPER RIGHT). Brightly-rayed craters are numerous on the lunar front side; however, they have not been previously observed in such detail on the farside.
AS11-42-6285 (July 1969) --- An Apollo 11 view of a bright rayed crater on the lunar farside. The crater is unnamed. The center of this photograph is located at 100 degrees southeast longitude and 4 degrees 30 minutes north latitude. This area is just east of Smyth's Sea.
NASA image release March 11, 2011 Caption: The lunar farside as never seen before! LROC WAC orthographic projection centered at 180° longitude, 0° latitude. Credit: NASA/Goddard/Arizona State University. Because the moon is tidally locked (meaning the same side always faces Earth), it was not until 1959 that the farside was first imaged by the Soviet Luna 3 spacecraft (hence the Russian names for prominent farside features, such as Mare Moscoviense). And what a surprise - unlike the widespread maria on the nearside, basaltic volcanism was restricted to a relatively few, smaller regions on the farside, and the battered highlands crust dominated. A different world from what we saw from Earth. Of course, the cause of the farside/nearside asymmetry is an interesting scientific question. Past studies have shown that the crust on the farside is thicker, likely making it more difficult for magmas to erupt on the surface, limiting the amount of farside mare basalts. Why is the farside crust thicker? That is still up for debate, and in fact several presentations at this week's Lunar and Planetary Science Conference attempt to answer this question. The Clementine mission obtained beautiful mosaics with the sun high in the sky (low phase angles), but did not have the opportunity to observe the farside at sun angles favorable for seeing surface topography. This WAC mosaic provides the most complete look at the morphology of the farside to date, and will provide a valuable resource for the scientific community. And it's simply a spectacular sight! The Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) is a push-frame camera that captures seven color bands (321, 360, 415, 566, 604, 643, and 689 nm) with a 57-km swath (105-km swath in monochrome mode) from a 50 km orbit. One of the primary objectives of LROC is to provide a global 100 m/pixel monochrome (643 nm) base map with incidence angles between 55°-70° at the equator, lighting that is favorable for morphological interpretations. Each month, the WAC provides nearly complete coverage of the Moon under unique lighting. As an added bonus, the orbit-to-orbit image overlap provides stereo coverage. Reducing all these stereo images into a global topographic map is a big job, and is being led by LROC Team Members from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). Several preliminary WAC topographic products have appeared in LROC featured images over the past year (Orientale basin, Sinus Iridum). For a sneak preview of the WAC global DEM with the WAC global mosaic, view a rotating composite moon (70 MB video from ASU's LROC website). The WAC topographic dataset will be completed and released later this year. The global mosaic released today is comprised of over 15,000 WAC images acquired between November 2009 and February 2011. The non-polar images were map projected onto the GLD100 shape model (WAC derived 100 m/pixel DTM), while polar images were map projected on the LOLA shape model. In addition, the LOLA derived crossover corrected ephemeris, and an improved camera pointing, provide accurate positioning (better than 100 m) of each WAC image. As part of the March 2011 PDS release, the LROC team posted the global map in ten regional tiles. Eight of the tiles are equirectangular projections that encompass 60° latitude by 90° longitude. In addition, two polar stereographic projections are available for each pole from ±60° to the pole. These reduced data records (RDR) products will be available for download on March 15, 2011. As the mission progresses, and our knowledge of the lunar photometric function increases, improved and new mosaics will be released! Work your way around the moon with these six orthographic projections constructed from WAC mosaics. The nearside view linked below is different from that released on 21 February.

AS16-120-19228 (16-27 April 1972) --- Strongly textured terrain north of the lunar farside King Crater which is centered near 120.5 degrees east longitude and 5.5 degrees north latitude. This near vertical oblique view eastward was photographed from the Apollo 16 spacecraft in lunar orbit with a Hasselblad camera equipped with a 250mm telephoto lens. Several irregular areas characterized by conspicuously smooth surfaces interrupt the rough texture in this view of the eastern quarter of the large, unnamed crater between King and Guyot. Similar "ponds" occur at varied levels in the rim deposits of the nearside craters Copernicus and Tycho. Hold picture with the smooth area at the top.

This artist's concept shows a cutaway of Mars along with the paths of seismic waves from two separate quakes in 2021. These seismic waves, detected by NASA's InSight mission, were the first ever identified to enter another planet's core. InSight's seismometer allowed scientists to study these waves and gain an unprecedented look at the Martian core. The quakes were detailed in a paper published April 24, 2023, in the Proceedings of the National Academies of Sciences. Occurring on Aug. 25 and Sept. 18, 2021, the two temblors were the first identified by the InSight team to have originated on the opposite side of the planet from the lander – so-called farside quakes. The distance proved crucial: The farther a quake happens from InSight, the deeper into the planet its seismic waves can travel before being detected. https://photojournal.jpl.nasa.gov/catalog/PIA25827
AS08-13-2244 (21-27 Dec. 1968) --- This Apollo 8 view of the lunar surface looks southward at 162 degrees west longitude, showing rugged terrain that is characteristic of the lunar farside hemisphere. Hold picture with black sky at top right. The large crater at the left side of the picture is about 110 kilometers (70 statute miles) in diameter and is centered about 200 kilometers (125 statute miles) south of the spacecraft. The sharp, circular crater in the foreground is about 15 kilometers (9 statute miles) across. Conspicuous surface lineations that extend from the lower right corner of the photograph toward the upper left resemble a radial texture observed near Mare Orientale on Lunar Orbiter IV photographs. The lineations in this area probably are related to another major crater because the observed trend is not radial to Mare Orientale.
About 50,000 Clementine images were processed to produce the four orthographic views of the Moon. The images show albedo variations (normalized brightness or reflectivity) of the surface at a wavelength of 750 nm (just longward of visible red). The image projection is centered at 0 degree latitude and 180 degrees longitude. Mare Moscoviense (dark albedo feature upper left of image center) and South Pole-Aitken Basin (dark feature at bottom) represent maria regions largely absent on the lunar farside. The Clementine altimeter showed Aitken Basin to consist of a topographic rim about 2500 km in diameter, an inner shelf ranging from 400 to 600 km in width, and an irregular depressed floor about 12 km in depth. http://photojournal.jpl.nasa.gov/catalog/PIA00303

AS12-47-6949 (19-20 Nov. 1969) --- A photograph of the Apollo 12 lunar landing site taken during the extravehicular activity (EVA) of astronauts Charles Conrad Jr., commander; and Alan L. Bean, lunar module pilot. The Apollo 12 Lunar Module (LM) is on the left. Barely visible in the center of the picture, in the shadows on the farside of the crater, is the Surveyor 3 spacecraft. The two spacecraft are about 600 feet apart. Conrad and Bean walked over to Surveyor 3 during their second EVA. The television camera and several other pieces were taken from Surveyor 3 and brought back to Earth for scientific examination. Astronaut Richard F. Gordon Jr., command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit, while astronauts Conrad and Bean descended in the LM to explore the moon. The considerable glare in the picture is caused by the position of the sun. The Apollo tool carrier is the object next to the LM footpad.
NASA's Lunar Reconnaissance Orbiter (LRO) recently captured a unique view of Earth from the spacecraft's vantage point in orbit around the moon. "The image is simply stunning," said Noah Petro, Deputy Project Scientist for LRO at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The image of the Earth evokes the famous 'Blue Marble' image taken by Astronaut Harrison Schmitt during Apollo 17, 43 years ago, which also showed Africa prominently in the picture." In this composite image we see Earth appear to rise over the lunar horizon from the viewpoint of the spacecraft, with the center of the Earth just off the coast of Liberia (at 4.04 degrees North, 12.44 degrees West). The large tan area in the upper right is the Sahara Desert, and just beyond is Saudi Arabia. The Atlantic and Pacific coasts of South America are visible to the left. On the moon, we get a glimpse of the crater Compton, which is located just beyond the eastern limb of the moon, on the lunar farside. LRO was launched on June 18, 2009, and has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the moon. LRO experiences 12 earthrises every day; however the spacecraft is almost always busy imaging the lunar surface so only rarely does an opportunity arise such that its camera instrument can capture a view of Earth. Occasionally LRO points off into space to acquire observations of the extremely thin lunar atmosphere and perform instrument calibration measurements. During these movements sometimes Earth (and other planets) pass through the camera's field of view and dramatic images such as the one shown here are acquired. This image was composed from a series of images taken Oct. 12, when LRO was about 83 miles (134 kilometers) above the moon's farside crater Compton. Capturing an image of the Earth and moon with LRO's Lunar Reconnaissance Orbiter Camera (LROC) instrument is a complicated task. First the spacecraft must be rolled to the side (in this case 67 degrees), then the spacecraft slews with the direction of travel to maximize the width of the lunar horizon in LROC's Narrow Angle Camera image. All this takes place while LRO is traveling faster than 3,580 miles per hour (over 1,600 meters per second) relative to the lunar surface below the spacecraft! The high-resolution Narrow Angle Camera (NAC) on LRO takes black-and-white images, while the lower resolution Wide Angle Camera (WAC) takes color images, so you might wonder how we got a high-resolution picture of the Earth in color. Since the spacecraft, Earth, and moon are all in motion, we had to do some special processing to create an image that represents the view of the Earth and moon at one particular time. The final Earth image contains both WAC and NAC information. WAC provides the color, and the NAC provides high-resolution detail. "From the Earth, the daily moonrise and moonset are always inspiring moments," said Mark Robinson of Arizona State University in Tempe, principal investigator for LROC. "However, lunar astronauts will see something very different: viewed from the lunar surface, the Earth never rises or sets. Since the moon is tidally locked, Earth is always in the same spot above the horizon, varying only a small amount with the slight wobble of the moon. The Earth may not move across the 'sky', but the view is not static. Future astronauts will see the continents rotate in and out of view and the ever-changing pattern of clouds will always catch one's eye, at least on the nearside. The Earth is never visible from the farside; imagine a sky with no Earth or moon - what will farside explorers think with no Earth overhead?" NASA's first Earthrise image was taken with the Lunar Orbiter 1 spacecraft in 1966. Perhaps NASA's most iconic Earthrise photo was taken by the crew of the Apollo 8 mission as the spacecraft entered lunar orbit on Christmas Eve Dec. 24, 1968. That evening, the astronauts -- Commander Frank Borman, Command Module Pilot Jim Lovell, and Lunar Module Pilot William Anders -- held a live broadcast from lunar orbit, in which they showed pictures of the Earth and moon as seen from their spacecraft. Said Lovell, "The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth."

AS08-14-2506 (21-27 Dec. 1968) --- This photograph of a nearly full moon was taken from the Apollo 8 spacecraft at a point above 70 degrees east longitude. (Hold picture with moon's dark portion at left). Mare Crisium, the circular, dark-colored area near the center, is near the eastern edge of the moon as viewed from Earth. Mare Nectaris is the circular mare near the terminator. The large, irregular maira are Tranquillitatis and Fecunditatis. The terminator at left side of picture crosses Mare Tranquillitatis and highlands to the south. Lunar farside features occupy most of the right half of the picture. The large, dark-colored crater Tsiolkovsky is near the limb at the lower right. Conspicuous bright rays radiate from two large craters, one to the north of Tsiolkovsky, the other near the limb in the upper half of the picture. These rayed craters were not conspicuous in Lunar Orbiter photography due to the low sun elevations when the Lunar Orbiter photography was made. The crater Langrenus is near the center of the picture at the eastern edge of Mare Fecunditatis. The lunar surface probably has less pronounced color that indicated by this print.
