NASA begins planning new Mars Orbiter with advanced communications and imaging technology

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA is soliciting ideas from U.S. industry for designs of a Mars orbiter for potential launch in the 2020s. The satellite would provide advanced communications and imaging, as well as robotic science exploration, in support of NASA’s Journey to Mars.

The orbiter would substantially increase bandwidth communications and maintain high-resolution imaging capability. It also may use experimental cutting-edge technologies, such as high-power solar electric propulsion or an optical communications package, which could greatly improve transmission speed and capacity over radio frequency systems.

NASA’s New Horizons spacecraft examines the layers of Pluto’s atmosphere

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scientists on NASA’s New Horizons mission team are learning more about the structure and behavior of Pluto’s complex atmosphere by discovering new attributes of its extensive haze layers. The hazes were first discovered by New Horizons in July, as the spacecraft swept past Pluto and made its historic first exploration of the mysterious world.

Mission scientists have discovered that the layers of haze in Pluto’s nitrogen atmosphere vary in brightness depending on illumination and viewpoint, yet the haze itself maintains its overall vertical structure.

NASA will connect Bigelow Expandable Activity Module to International Space Station, Saturday

 

Written by Cheryl Warner
NASA’s Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The first human-rated expandable structure that may help inform the design of deep space habitats is set to be installed to the International Space Station Saturday, April 16th. NASA Television coverage of the installation will begin at 5:30am EDT.

The Bigelow Expandable Activity Module (BEAM) will be attached to the station’s Tranquility module over a period of about four hours. Controllers in mission control at NASA’s Johnson Space Center in Houston will remove BEAM from the unpressurized trunk of SpaceX’s Dragon spacecraft, using the robotic Canadarm2, and move it into position next to Tranquility’s aft assembly port.

NASA’s NEOWISE spacecraft continues to identify potentially hazardous near-Earth objects

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Near-Earth Object Wide-field Survey Explorer (NEOWISE) mission has released its second year of survey data. The spacecraft has now characterized a total of 439 NEOs since the mission was re-started in December 2013. Of these, 72 were new discoveries.

Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of the giant planets in our solar system into orbits that allow them to enter Earth’s neighborhood. Eight of the objects discovered in the past year have been classified as potentially hazardous asteroids (PHAs), based on their size and how closely their orbits approach Earth.

NASA’s Mars Opportunity rover spots Dust Devil on Mars

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – From its perch high on a ridge, NASA’s Mars Exploration Rover Opportunity recorded this image of a Martian dust devil twisting through the valley below. The view looks back at the rover’s tracks leading up the north-facing slope of “Knudsen Ridge,” which forms part of the southern edge of “Marathon Valley.”

Opportunity took the image using its navigation camera (Navcam) on March 31st, 2016, during the 4,332nd Martian day, or sol, of the rover’s work on Mars.

NASA’s Mars Opportunity rover tackles highest angled slope ever attempted on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s long-lived Mars rover Opportunity is driving to an alternative hillside target after a climb on the steepest slope ever tackled by any Mars rover. Opportunity could not quite get within reach of a target researchers hoped the rover could touch earlier this month.

A new image shows the view overlooking the valley below and catches the rover’s own shadow and wheel tracks as Opportunity heads toward its next target.

A shadow and tracks of NASA's Mars rover Opportunity appear in this March 22, 2016, image, which has been rotated 13.5 degrees to adjust for the tilt of the rover. (NASA/JPL-Caltech)

NASA uses Microsoft HoloLens mixed reality headset to create guided tour of Mars

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – What might it look like if you were walking around on Mars? A group of researchers at NASA’s Jet Propulsion Laboratory, Pasadena, California, has been working on methods to take this question from the realm of imagination to the mind-bending domain of mixed reality.

As a result, NASA and Microsoft have teamed up to offer the public a guided tour of an area of Mars with astronaut Buzz Aldrin this summer in “Destination: Mars,” an interactive exhibit using the Microsoft HoloLens mixed reality headset. “Mixed reality” means that virtual elements are merged with the user’s actual environment, creating a world in which real and virtual objects can interact.

Erisa Hines, a driver for the Mars Curiosity rover, based at JPL, also talks to participants in "Destination: Mars." (NASA/JPL-Caltech/Microsoft)

NASA’s Dawn Spacecraft provides high resolution details of Bright Spots and complex features on Dwarf Planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists from NASA’s Dawn mission unveiled new images from the spacecraft’s lowest orbit at Ceres, including highly anticipated views of Occator Crater, at the 47th annual Lunar and Planetary Science Conference in The Woodlands, Texas, on Tuesday.

Occator Crater, measuring 57 miles (92 kilometers) across and 2.5 miles (4 kilometers) deep, contains the brightest area on Ceres, the dwarf planet that Dawn has explored since early 2015. The latest images, taken from 240 miles (385 kilometers) above the surface of Ceres, reveal a dome in a smooth-walled pit in the bright center of the crater.

NASA Spacecrafts orbiting Mars make revealing Gravity Map of the Red Planet

 

Written by William Steigerwald / Nancy Neal Jones

NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A new map of Mars’ gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet.

“Gravity maps allow us to see inside a planet, just as a doctor uses an X-ray to see inside a patient,” said Antonio Genova of the Massachusetts Institute of Technology (MIT), Cambridge. “The new gravity map will be helpful for future Mars exploration, because better knowledge of the planet’s gravity anomalies helps mission controllers insert spacecraft more precisely into orbit about Mars”

This Mars map shows variations in thickness of the planet's crust, the relatively thin surface layer overlying the mantle of the planet. It shows unprecedented detail derived from new mapping of variations in Mars' gravitational pull on orbiters. (NASA/GSFC/Scientific Visualization Studio)

NASA’s MAVEN orbiter observes Comet Siding Spring create havoc with Mars’ Magnetic Field during flyby

 

Written by Elizabeth Zubritsky
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Just weeks before the historic encounter of comet C/2013 A1 (Siding Spring) with Mars in October 2014, NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft entered orbit around the Red Planet.

To protect sensitive equipment aboard MAVEN from possible harm, some instruments were turned off during the flyby; the same was done for other Mars orbiters. But a few instruments, including MAVEN’s magnetometer, remained on, conducting observations from a front-row seat during the comet’s remarkably close flyby.

A close encounter between a comet and Mars in 2014 flooded Mars with an invisible tide of charged particles. The comet's strong magnetic field temporarily merged with, and overwhelmed, the planet's weak magnetic field, as shown in this artist's depiction. NASA's MAVEN mission monitored the effects.
