You can download the new app here. JPL developed the Spacecraft AR app in collaboration with Google. The app uses Google’s ARCore technology to bring 3-D spacecraft into users’ devices using native mobile augmented reality. (“Native mobile” AR uses the built-in capabilities of a mobile device to interact with 3-D environments and objects.) ![]() The free Spacecraft AR app uses Google ARCore technology to put virtual 3-D models of NASA robotic spacecraft, such as the Curiosity Mars rover seen here, into any environment with a flat surface.

NASA looks back at America’s first Satellite, Explorer 1Written by Preston Dyches
The date was January 31st, 1958. NASA had yet to be formed, and the honor of this first flight belonged to the U.S. Army. The rocket’s sole payload was a javelin-shaped satellite built by the Jet Propulsion Laboratory in Pasadena, California. Explorer 1, as it would soon come to be called, was America’s first satellite. «Read the rest of this article» Sections: Technology | No Comments
A Last Look at Saturn from NASA’s Cassini SpacecraftWritten by Preston Dyches
Cassini’s wide-angle camera acquired 42 red, green and blue images, covering the planet and its main rings from one end to the other, on September 13th, 2017. Imaging scientists stitched these frames together to make a natural color view. The scene also includes the moons Prometheus, Pandora, Janus, Epimetheus, Mimas and Enceladus. ![]() After more than 13 years at Saturn, and with its fate sealed, NASA’s Cassini spacecraft bid farewell to the Saturnian system by firing the shutters of its wide-angle camera and capturing this last, full mosaic of Saturn and its rings two days before the spacecraft’s dramatic plunge into the planet’s atmosphere.

New Study using NASA’s Cassini Spacecraft data reveals heat from friction may power Hydrothermal Activity on Saturn’s Moon EnceladusWritten by Preston Dyches
The study, published today in the journal Nature Astronomy, helps resolve a question scientists have grappled with for a decade: Where does the energy to power the extraordinary geologic activity on Enceladus come from? ![]() This graphic from ESA (the European Space Agency) illustrates how water might be heated inside Saturn’s moon Enceladus.

NASA releases new findings from Cassini Spacecraft’s observations of SaturnWritten by Preston Dyches
Some of the Cassini team’s freshest insights were presented during a news conference today at the American Astronomical Society Division for Planetary Science meeting in Provo, Utah. ![]() Cassini obtained this panoramic view of Saturn’s rings on Sept. 9, 2017, just minutes after it passed through the ring plane.

NASA looks back at Cassini spacecraft’s dive into SaturnWritten by Preston Dyches
While analysis of science data from the final plunge will take some time, Cassini engineers already have a pretty clear understanding of how the spacecraft itself behaved as it went in. The data are useful for evaluating models of Saturn’s atmosphere the team used to predict the spacecraft’s behavior at mission’s end, and they help provide a baseline for planning future missions to Saturn. ![]() NASA’s Cassini spacecraft is shown during its Sept. 15, 2017, plunge into Saturn’s atmosphere in this artist’s depiction.

NASA’s Cassini spacecraft makes final flyby of Saturn’s moon TitanWritten by Preston Dyches
The spacecraft made its closest approach to Titan today at 12:04pm PDT (3:04pm EDT), at an altitude of 73,974 miles (119,049 kilometers) above the moon’s surface. The spacecraft is scheduled to make contact with Earth on September 12th at about 6:19pm PDT (9:19pm EDT). ![]() Cassini made its final, distant flyby of Saturn’s moon Titan on Sept. 11, which set the spacecraft on its final dive toward the planet.

NASA’s Cassini spacecraft to make final plunge into Saturn September 15thWritten by Preston Dyches
Yet several mission milestones have to occur over the coming two-plus weeks to prepare the vehicle for one last burst of trailblazing science. ![]() NASA’s Cassini spacecraft is shown heading for the gap between Saturn and its rings during one of 22 such dives of the mission’s finale in this illustration. The spacecraft will make a final plunge into the planet’s atmosphere on September 15th. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Cassini Spacecraft continues dives between Saturn and it’s RingsWritten by Preston Dyches
Other recent science highlights include promising hints about the structure and composition of the icy rings, along with high-resolution images of the rings and Saturn’s atmosphere. ![]() Recent images of features in Saturn’s C ring called “plateaus” reveal a streaky texture that is very different from the textures of the regions around them.

NASA studies possible missions to Uranus and NeptuneWritten by Preston Dyches
The results of this and future studies will be used as the Decadal Survey deliberates on NASA’s planetary science priorities from 2022-2032. The study identifies the scientific questions an ice giant mission should address, and discusses various instruments, spacecraft, flight-paths and technologies that could be used. ![]() Left: Arriving at Uranus in 1986, Voyager 2 observed a bluish orb with subtle features. A haze layer hid most of the planet’s cloud features from view. Right: This image of Neptune was produced from Voyager 2 and shows the Great Dark Spot and its companion bright smudge.
