Saturn's Rings by Sunlight | NASA Cassini

Color-composite of raw images acquired in visible light by NASA's Cassini spacecraft on Nov. 4, 2006.

Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It has only one-eighth the average density of Earth, but with its larger volume, Saturn is over 95 times more massive. Saturn is a gas giant because it is predominantly composed of hydrogen and helium. It lacks a definite surface, though it may have a solid core.

NASA's 60th Anniversary (1958-2018)

Friends of NASA Celebrates its 10th Anniversary (2008-2018)
From 2018 through 2022, NASA is marking a series of important milestones—the 60th anniversary of the agency’s founding by Congress in 1958, and the 50th anniversary of the Apollo missions that put a dozen Americans on the Moon between July 1969 and December 1972.

Celebrations already are under way. Some are complete, some are scheduled in the coming months, and some are still being planned.

July 29, 2018 marked 60 years since President Dwight D. Eisenhower established NASA as a U.S. government agency by signing Public Law 58-568, the National Aeronautics and Space Act. The act consolidated several federal and military research organizations, including the National Advisory Committee for Aeronautics, under one agency.

The new agency was given responsibility to plan, direct and conduct U.S. civil aeronautics and space activities and share the results of those activities as widely as practicable. NASA opened for business about two months later, on Oct. 1, 1958—the date NASA observes as its birthday.

NASA kicked off its 60th anniversary Jan. 31 by remembering the 1958 launch of the first U.S. satellite, Explorer 1, from Cape Canaveral, Florida. An experiment on the satellite discovered belts of charged particles trapped in space by Earth’s magnetic field, now known as the Van Allen Belts.

The celebrations continued June 1-2 with "Space, the Next Frontier," a tribute to NASA by the National Symphony Orchestra Pops at the Kennedy Center for the Performing Arts in Washington. The center is named for President John F. Kennedy, who had not only a vision for cultural advancement, but also a vision for technological advancement in the form of landing Americans on the Moon. Kennedy’s legacy to the space program is highlighted along with six decades of NASA achievements in an exhibition at the Kennedy Center’s Hall of Nations May 27-June 3.

The public will be invited to celebrate with the agency in September and October. Special activities are being planned at several NASA visitor centers and other locations across the United States. Details will be announced as they become available.

NASA’s celebration of all things Apollo will begin Oct. 11, the 50th anniversary of the launch of Apollo 7, the first of the missions to carry a crew into space. On this day, at the National Air and Space Museum in Washington, the U.S. Mint will unveil the design for an Apollo 11 commemorative coin that will go on sale in January 2019.

In December, NASA will join the National Air and Space Museum in recalling the 50th anniversary of the flight of Apollo 8, whose crew of three spent Christmas 1968 in orbit around the Moon.

The focus will turn to Apollo 11 in July 2019. Celebrations are planned in Washington and at NASA centers that were crucial to the success of the Apollo Program. On July 19, NASA TV will broadcast live from the refurbished Apollo Mission Operations Control Room at NASA’s Johnson Space Center and several other locations with Apollo connections coast to coast.

Sahara Desert Sandstorm | International Space Station

U.S. Astronaut Ricky Arnold: "A massive sandstorm rolls across the Sahara."

The Sahara is the largest hot desert and the third largest desert in the world after Antarctica and the Arctic. Its area of 9,200,000 square kilometers (3,600,000 sq mi) is comparable to the area of China or the United States. The name 'Sahara' is derived from a dialectal Arabic word for "desert", ṣaḥra.

The desert comprises much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and Sudan. It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south, it is bounded by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and the Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions including: the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, the Ténéré desert, and the Libyan Desert.

NASA's Parker Solar Probe: Prepping for Launch

Launch targeted for August 11, 2018

NASA’s Parker Solar Probe has cleared the final procedures in the clean room before its move to the launch pad, where it will be integrated onto its launch vehicle, a United Launch Alliance Delta IV Heavy. This is an historic mission that will revolutionize our understanding of the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds. Parker Solar Probe will travel through the Sun’s atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions—and ultimately providing humanity with the closest-ever observations of a star.

Seen here inside one half of its 62.7-foot tall fairing, the Parker Solar Probe was encapsulated on July 16, 2018, in preparation for the move from Astrotech Space Operations in Titusville, Florida, to Space Launch Complex 37 on Cape Canaveral Air Force Station, where it will be integrated onto its launch vehicle for its launch that is targeted for August 11, 2018.

Understanding Lunar Eclipses | NASA

It's not often that we get a chance to see our planet's shadow, but a lunar eclipse gives us a fleeting glimpse. During these rare events, the full Moon rapidly darkens and then glows red as it enters the Earth's shadow. Though a lunar eclipse can be seen only at night, it's worth staying up to catch the show. ​The next lunar eclipse that can be seen all over the U.S. will be on Jan. 21, 2019. It will also be a supermoon. The January 2019 a total lunar eclipse will be visible in the Americas, Europa, Africa and the Central Pacific.

NASA's Space to Ground: Locally Grown | Week of July 27, 2018

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. NASA astronauts Drew Feustel and Serena Auñón-Chancellor continued a second week of research operations to gain fundamental data about fertility in space. The duo examined biological samples in a microscope and stowed them in a science freezer for later analysis. The Micro-11 study is exploring the possibility of human reproduction in space including ways to address aging problems on Earth.

Alexander Gerst, of the European Space Agency, explored the sedimentary properties of quartz and clay particles. The German astronaut mixed quartz and clay samples suspended in a liquid for photographic and video downlink to scientists on Earth. Observations can help guide future geological studies of unexplored planets and improve petroleum exploration here on Earth.

Expedition 56 Flight Engineer Ricky Arnold of NASA split his time working on a variety of science gear that examines different microscopic properties. He set up Aerosol Samplers in the Harmony and Tranquility modules to collect airborne particles in the station’s air cabin for analysis. Arnold later stowed a Biomolecule Sequencer he used this month to sequence DNA extracted from microbes living on space station surfaces.

Mars: Liquid Water Found Under South Pole | ESA

Mars Express detects liquid water hidden under planet’s south pole
July 25, 2018: Radar data collected by the European Space Agency’s Mars Express spacecraft point to a pond of liquid water buried under layers of ice and dust in the south polar region of Mars. Evidence for the Red Planet’s watery past is prevalent across its surface in the form of vast dried-out river valley networks and gigantic outflow channels clearly imaged by orbiting spacecraft. Orbiters, together with landers and rovers exploring the martian surface, also discovered minerals that can only form in the presence of liquid water.

But the climate has changed significantly over the course of the planet’s 4.6 billion year history and liquid water cannot exist on the surface today, so scientists are looking underground. Early results from the 15-year old Mars Express spacecraft already found that water-ice exists at the planet’s poles and is also buried in layers interspersed with dust.

The presence of liquid water at the base of the polar ice caps has long been suspected; after all, from studies on Earth, it is well known that the melting point of water decreases under the pressure of an overlying glacier. Moreover, the presence of salts on Mars could further reduce the melting point of water and keep the water liquid even at below-freezing temperatures.

But until now evidence from the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument, MARSIS, the first radar sounder ever to orbit another planet, remained inconclusive.

It has taken the persistence of scientists working with this subsurface-probing instrument to develop new techniques in order to collect as much high-resolution data as possible to confirm their exciting conclusion.

Ground-penetrating radar uses the method of sending radar pulses towards the surface and timing how long it takes for them to be reflected back to the spacecraft, and with what strength. The properties of the material that lies between influences the returned signal, which can be used to map the subsurface topography.

The radar investigation shows that south polar region of Mars is made of many layers of ice and dust down to a depth of about 1.5 km in the 200 km-wide area analysed in this study. A particularly bright radar reflection underneath the layered deposits is identified within a 20 km-wide zone.

Analysing the properties of the reflected radar signals and considering the composition of the layered deposits and expected temperature profile below the surface, the scientists interpret the bright feature as an interface between the ice and a stable body of liquid water, which could be laden with salty, saturated sediments. For MARSIS to be able to detect such a patch of water, it would need to be at least several tens of centimeters thick.

“This subsurface anomaly on Mars has radar properties matching water or water-rich sediments,” says Roberto Orosei, principal investigator of the MARSIS experiment and lead author of the paper published in the journal Science today:
http://science.sciencemag.org/content/early/2018/07/24/science.aar7268

“This is just one small study area; it is an exciting prospect to think there could be more of these underground pockets of water elsewhere, yet to be discovered.”

“We’d seen hints of interesting subsurface features for years but we couldn’t reproduce the result from orbit to orbit, because the sampling rates and resolution of our data was previously too low,” adds Andrea Cicchetti, MARSIS operations manager and a co-author on the new paper.

“We had to come up with a new operating mode to bypass some onboard processing and trigger a higher sampling rate and thus improve the resolution of the footprint of our dataset: now we see things that simply were not possible before.”

The finding is somewhat reminiscent of Lake Vostok, discovered some 4 km below the ice in Antarctica on Earth. Some forms of microbial life are known to thrive in Earth’s subglacial environments, but could underground pockets of salty, sediment-rich liquid water on Mars also provide a suitable habitat, either now or in the past? Whether life has ever existed on Mars remains an open question, and is one that Mars missions, including the current European-Russian ExoMars orbiter and future rover, will continue to explore.

“The long duration of Mars Express, and the exhausting effort made by the radar team to overcome many analytical challenges, enabled this much-awaited result, demonstrating that the mission and its payload still have a great science potential,” says Dmitri Titov, ESA’s Mars Express project scientist.

“This thrilling discovery is a highlight for planetary science and will contribute to our understanding of the evolution of Mars, the history of water on our neighbor planet and its habitability.”

Mars Express launched June 2, 2003 and celebrates 15 years in orbit on December 25 this year.

Galileo Satellite Mission: Ariane 5 Rocket Liftoff | ESA

Galileo: The world's first civilian Earth satellite navigation system
Europe’s next four Galileo navigation satellites lifted off on July 25, 2018 from Europe’s Spaceport in French Guiana atop an Ariane 5 launcher.

Galileo is the global navigation satellite system (GNSS) that is being created by the European Union (EU) through the European Space Agency (ESA), headquartered in Prague in the Czech Republic, with two ground operations centers, Oberpfaffenhofen near Munich in Germany and Fucino in Italy. The €10 billion project is named after the Italian astronomer Galileo Galilei. One of the aims of Galileo is to provide an independent high-precision positioning system so European nations do not have to rely on the Russian GLONASS, Chinese BeiDou or U.S. GPS systems, which could be disabled or degraded by their operators at any time.The use of basic (lower-precision) Galileo services will be free and open to everyone. The higher-precision capabilities will be available for paying commercial users. Galileo is intended to provide horizontal and vertical position measurements within 1-meter precision, and better positioning services at higher latitudes than other positioning systems.

Galileo is to provide a new global search and rescue (SAR) function as part of the MEOSAR system. Satellites will be equipped with a transponder which will relay distress signals from emergency beacons to the Rescue coordination center, which will then initiate a rescue operation.

French Guiana, officially called Guiana, is an overseas department and region of France, on the north Atlantic coast of South America in the Guyanas. It borders Brazil to the east and south and Suriname to the west. Since 1981, when Belize became independent, French Guiana has been the only territory of the mainland Americas that is still part of a European country.
