NASA’s Juno spacecraft discovers Changes in Magnetic Field of Jupiter

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The first definitive detection beyond our world of an internal magnetic field that changes over time was detected during NASA’s Juno mission to Jupiter. It’s a phenomenon called secular variation. The gas giant’s secular variation is most likely driven by the planet’s deep atmospheric winds, Juno determined.

The discovery will help scientists further understand Jupiter’s interior structure – including atmospheric dynamics – as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy.

NASA looks to Advance Human Moon Landers with help from 11 American Companies

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA looks to put American astronauts, the first woman and next man, on the Moon’s south pole by 2024 and establish sustainable missions by 2028. In order to do so, NASA has picked 11 companies to conduct studies and produce prototypes of human landers for its Artemis lunar exploration program.

“To accelerate our return to the Moon, we are challenging our traditional ways of doing business. We will streamline everything from procurement to partnerships to hardware development and even operations,” said Marshall Smith, director for human lunar exploration programs at NASA Headquarters.

NASA’s Mars 2020 Spacecraft nears completion

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Prior to a test in the Space Simulator Facility at NASA’s Jet Propulsion Laboratory in Pasadena, California, an engineer inspects the completed spacecraft that will carry NASA’s next Mars rover to the Red Planet.

From the top down, and suspended by cables, is the complete cruise stage, which will power and guide the Mars 2020 spacecraft on its seven-month voyage to the Red Planet. Directly below that is the aeroshell (white back shell and barely visible black heat shield), which will protect the vehicle during cruise as well as during its fiery descent into the Martian atmosphere.

NASA’s Mars Reconnaissance Orbiter finishes 60,000 trips around Mars

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Reconnaissance Orbiter completed 60,000 loops around the Red Planet at 10:39am PDT (12:39 pm CDT) on Wednesday morning, May 15th, 2019. On average, MRO takes 112 minutes to circle Mars, whipping around at about 2 miles per second (3.4 kilometers per second).

Since entering orbit on March 10th, 2006, the spacecraft has been collecting daily science about the planet’s surface and atmosphere, including detailed views with its High Resolution Imaging Science Experiment camera (HiRISE). HiRISE is powerful enough to see surface features the size of a dining room table from 186 miles (300 kilometers) above the surface.

NASA releases video of proposed route for Mars Curiosity Rover

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new animated video shows what it would be like to soar over Mount Sharp, which the NASA Curiosity rover has been climbing since 2014. If you have ever wanted to visit Mars, watch this video.

This video highlights several regions on the mountain that are intriguing to Curiosity’s scientists, chief among them what the science team calls the “clay-bearing unit,” where Curiosity has just started analyzing rock samples.

This image shows a proposed route for NASA's Curiosity rover, which is climbing lower Mount Sharp on Mars. The map labels different regions that scientists working with the rover would like to explore in coming years.

NASA study reveals Earth’s Moon has active, changing surface

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says the Earth’s Moon formed vast basins called “mare” (pronounced MAR-ay) over a billions of years ago. Scientists have long assumed these basins were dead, still places where the last geologic activity occurred long before dinosaurs roamed Earth.

But a survey of more than 12,000 images reveals that at least one lunar mare has been cracking and shifting as much as other parts of the Moon – and may even be doing so today. The study adds to a growing understanding that the Moon is an actively changing world.

New surface features of the Moon have been discovered in a region called Mare Frigoris, outlined here in teal. This image is a mosaic composed of many images taken by NASA's Lunar Reconnaissance Orbiter (LRO). (NASA)

NASA’s Grace satellites data reveals how Water moves on Earth

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA says when you hear news about an aquifer in California that is getting depleted, ice loss from Greenland or Antarctica,  or a new explanation for a wobble in Earth’s rotation, you might not realize that all these findings may rely on data from one single mission: the U.S.-German Gravity Recovery and Climate Experiment (GRACE).

GRACE data, collected from 2002 to 2017 while the mission was active, are still being used to improve our understanding of water in motion and its sometimes surprising effects on our planet.

NASA develops Flying Robots to help with work in Space

 

NASA - National Aeronautics and Space AdministrationMountain View, CA – Bees are known to be both busy and hard-working, and NASA’s new free-flying space robots, called Astrobee, will soon have the same reputation. Unlike bees that live on Earth, the robots will do their work flying alongside astronauts inside the International Space Station and will play a critical role in supporting innovative and sustainable exploration of the Moon, Mars and beyond.

Astrobee is a free-flying robot system that will provide a research platform for the orbiting laboratory. The system includes three robots—named Honey, Queen and Bumble— as well as a docking station for recharging.

NASA’s Kepler Space Telescope discovers Third Planet in Kepler-47 System

 

NASA - National Aeronautics and Space AdministrationMountain View, CA – Astronomers have discovered a third planet in the Kepler-47 system, securing the system’s title as the most interesting of the binary-star worlds. Using data from the NASA Kepler space telescope, a team of researchers, led by astronomers at San Diego State University, detected the new Neptune-to-Saturn-size planet orbiting between two previously known planets.

With its three planets orbiting two suns, Kepler-47 is the only known multi-planet circumbinary system. Circumbinary planets are those that orbit two stars.

NASA’s Mars Odyssey orbiter takes photos of Mars’ moon Phobos at full moon

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Odyssey orbiter has captured Mar’s moon Phobos during a full moon phase for the first time. Each color in this new image represents a temperature range detected by Odyssey’s infrared camera, which has been studying the Martian moon since September of 2017.

Looking like a rainbow-colored jawbreaker, these latest observations could help scientists understand what materials make up Phobos, the larger of Mars’ two moons.

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range. (NASA/JPL-Caltech/ASU/SSI)
