NASA to launch first pair of CubeSats designed for Deep Space

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Many of NASA’s most iconic spacecraft towered over the engineers who built them: think Voyager 1 and Voyager 2, Cassini or Galileo — all large machines that could measure up to a school bus.

But in the past two decades, mini-satellites called CubeSats have made space accessible to a new generation. These briefcase-sized boxes are more focused in their abilities and have a fraction of the mass — and cost — of some past titans of space.

In May, engineers will be watching closely as NASA launches its first pair of CubeSats designed for deep space. The twin spacecraft are called Mars Cube One, or MarCO, and were built at NASA’s Jet Propulsion Laboratory in Pasadena, California.

Virtual 3-D models of NASA’s Robotic Space Explorers in new “AR” Mobile App

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory Media Relations Office

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA spacecraft travel to far-off destinations in space, but a new mobile app produced by NASA’s Jet Propulsion Laboratory, Pasadena, California, brings spacecraft to users. The new app, called Spacecraft AR, uses the latest augmented reality (AR) technology to put virtual 3-D models of NASA’s robotic space explorers into any environment with a flat surface.

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/JPL-Caltech)

NASA’s Kepler Mission to end when Spacecraft runs out of Fuel

 

Written by Charlie Sobeck
NASA’s Kepler Space Telescope mission

NASA - National Aeronautics and Space AdministrationSilicon Valley, CA – Trailing Earth’s orbit at 94 million miles away, the Kepler space telescope has survived many potential knock-outs during its nine years in flight, from mechanical failures to being blasted by cosmic rays.

At this rate, the hardy spacecraft may reach its finish line in a manner we will consider a wonderful success. With nary a gas station to be found in deep space, the spacecraft is going to run out of fuel. We expect to reach that moment within several months.

In 2013, Kepler’s primary mission ended when a second reaction wheel broke, rendering it unable to hold its gaze steady at the original field of view.

NASA’s Cassini Spacecraft data reveals Saturn’s moon Titan has Sea Level elevation

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA –  Saturn’s moon Titan may be nearly a billion miles away from Earth, but a recently published paper based on data from NASA’s Cassini spacecraft reveals a new way this distant world and our own are eerily similar. Just as the surface of oceans on Earth lies at an average elevation that we call “sea level,” Titan’s seas also lie at an average elevation.

This is the latest finding that shows remarkable similarities between Earth and Titan, the only other world we know of in our solar system that has stable liquid on its surface.

Ligeia Mare, shown in here in data obtained by NASA's Cassini spacecraft, is the second largest known body of liquid on Saturn's moon Titan. It is filled with liquid hydrocarbons, such as ethane and methane, and is one of the many seas and lakes that bejewel Titan's north polar region. (NASA/JPL-Caltech/ASI/Cornell)

NASA’s Jet Propulsion Laboratory 2018 Missions and Activities

 

Written by Elyssia Widjaja
NASA’s Jet Propulsion Laboratory Newsroom

NASA - National Aeronautics and Space AdministrationPasadena, CA – The year 2017 marked several milestones in science, technology and flight projects for NASA’s Jet Propulsion Laboratory, Pasadena, California. Voyager 1 returned data from interstellar space as it surpassed 40 years in flight.

NASA’s Cassini Spacecraft ended its 13-year tour of Saturn. JPL celebrated the 25th anniversary of the launch of the Earth-orbiting Topex/Poseidon satellite.

As JPL turns 82 in 2018, its missions and activities will continue to inspire. Here is a preview of events planned for JPL (some dates subject to change):

NASA 2017 Highlights

 

Written by Jen Rae Wang / Allard Beutel
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The Moon became a key focus point for NASA in 2017, whether it was blocking out the Sun during one of the most-viewed events in U.S. history, or reinvigorating the agency’s human space exploration plans.

One of the numerous NASA-related activities and actions the Trump Administration did in 2017 was to reconstitute the National Space Council. During its first meeting on October 5th, Vice President Mike Pence directed NASA to develop a plan to help extend human exploration across our solar system, and return astronauts to the Moon in preparation for human missions to Mars and other destinations.

A Last Look at Saturn from NASA’s Cassini Spacecraft

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In a fitting farewell to the planet that had been its home for over 13 years, the Cassini spacecraft took one last, lingering look at Saturn and its splendid rings during the final leg of its journey and snapped a series of images that has been assembled into a new mosaic. 

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 Enceladus

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Heat from friction could power hydrothermal activity on Saturn’s moon Enceladus for billions of years if the moon has a highly porous core, according to a new modeling study by European and U.S. researchers working on NASA’s Cassini mission.

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. (ESA/NASA/JPL-Caltech/SSI/LPG-CNRS/U. Nantes/U. Angers)

NASA releases new findings from Cassini Spacecraft’s observations of Saturn

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft ended its journey on September 15th, 2017 with an intentional plunge into the atmosphere of Saturn, but analysis continues on the mountain of data the spacecraft sent during its long life.

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/JPL-Caltech/Space Science Institute)

NASA looks back at Cassini spacecraft’s dive into Saturn

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA’s Cassini spacecraft made its fateful dive into the upper atmosphere of Saturn on September 15th, 2017, the spacecraft was live-streaming data from eight of its science instruments, along with readings from a variety of engineering systems.

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.
