Shrouded in clouds today in 1969, this image was taken by the crew of Apollo 10 as they began their lunar journey. From 36,000 nautical miles away, this full disk view of our home planet shows the crew’s vantage point from space.

The crew members on Apollo 10 were astronauts Thomas P. Stafford, commander; John W. Young, command module pilot; and Eugene E. Cernan, lunar module pilot. Astronaut Young remained in lunar orbit, in the Command and Service Module (CSM) “Charlie Brown”, while astronauts Stafford and Cernan descended to within nine miles of the lunar surface, in the Lunar Module (LM) “Snoopy”.

Saturn’s shadow on the rings grows shorter as the northern hemisphere advances toward summer, thanks to the planet’s permanent tilt as it orbits the sun. This will continue until the solstice later this month. Then, the shadow will extend only as far as the innermost A ring.
The image was taken in visible light with the Cassini spacecraft wide-angle camera on Feb. 3, 2017. The view was acquired at a distance of approximately 760,000 miles (1.2 million kilometers) from Saturn.

At the edge of the sun, a large prominence and a small prominence began to shift, turn and fall apart in less than one day on May 8-9, 2017. Prominences are notoriously unstable. Competing magnetic forces pulled the plasma back and forth until they dissipated. The images were taken in a wavelength of extreme ultraviolet light. The 18-second video clip is comprised of almost 600 frames being shown at 30 frames per second.

Saturn’s hexagonal polar jet stream shines with the glow of reflected sunlight in this image taken by our Cassini spacecraft. The sunlight falling on Saturn’s north pole, which is just enough to allow us to image and study the region, does not provide much warmth. In addition to being low in the sky (just like summer at Earth’s poles), the sun is nearly ten times as distant from Saturn as from Earth and is only about 1 percent as intense as on Earth.

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by our Solar Dynamics Observatory on April 24-26, 2017.
These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in this wavelength of extreme ultraviolet light. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold. This video covers almost two days of activity.

We did it! Our Cassini spacecraft successfully dove through the gap between Saturn and its rings – an area previously unexplored by any spacecraft!
These unprocessed images show features in Saturn’s atmosphere from closer than ever before! These views were captured by our Cassini spacecraft during its first Grand Finale dive between the planet and its rings on April 26, 2017.

As Cassini dove through the gap, it came within about 1,900 miles (3,000 kilometers) of Saturn’s cloud tops (where the air pressure is 1 bar – comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.

Space ravioli? No, it’s Saturn’s moon Pan. These raw, unprocessed images of Saturn’s tiny moon, Pan, were taken on March 7 by our Cassini spacecraft. The flyby had a close-approach distance of 24,572 kilometers (15,268 miles).
These images are the closest images ever taken of Pan and will help to characterize its shape and geology.

Engineers successfully tested the parachutes for our Orion spacecraft at the U.S. Army Yuma Proving Ground in Arizona Wednesday. This was the second test in a series of eight that will certify Orion’s parachutes for human spaceflight. The test, which dropped an Orion engineering model from a C-17 aircraft at 25,000 feet, simulated the descent astronauts might experience if they have to abort a mission after liftoff.
Orion, which will launch atop our new Space Launch System rocket, is built to take astronauts farther into the solar system than ever before. The spacecraft will carry crew to space, provide emergency abort capabilities, sustain the crew during their mission and provide safe re-entry through Earth’s atmosphere.

Pandora Up Close: This image from our Cassini spacecraft is one of the highest-resolution views ever taken of Saturn’s moon Pandora. Pandora (52 miles, 84 kilometers) across orbits Saturn just outside the narrow F ring.
The spacecraft captured the image during its closest-ever flyby of Pandora on Dec. 18, 2016, during the third of its grazing passes by the outer edges of Saturn’s main rings. The image was taken in green light with the Cassini spacecraft narrow-angle camera at a distance of approximately 25,200 miles (40,500 kilometers) from Pandora. Image scale is 787 feet (240 meters) per pixel.

Japanese Cargo Craft Approaches Space Station: Station Commander Shane Kimbrough of NASA shared this photograph of the Japan Aerospace Exploration Agency’s Kounotori H-II Transfer Vehicle (HTV-6) as it approached the International Space Station (@ISS) today, writing, “Beautiful #HTV6 Space Station. @NASA and @EuropeanSpaceAgency astronauts using station’s robot arm to capture the spacecraft. Proud of Int’l. #Teamwork”

Kimbrough and Flight Engineer Thomas Pesquet of ESA successfully captured the 12-ton spacecraft using the @canadianspaceagency’s robotic arm. Robotic ground controllers then installed it on the Earth-facing side of the Harmony module. Flight Engineer Peggy Whitson of NASA monitored HTV-6 systems during the rendezvous and grapple. The unpiloted cargo spacecraft is loaded with more than 4.5 tons of supplies, water, spare parts and experiment hardware for the six-person station crew.
