NASA to send high tech legs to International Space Station for Robonaut

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s built and is sending a set of high-tech legs up to the International Space Station for Robonaut 2 (R2), the station’s robotic crewmember. The new legs will be delivered to the space station aboard the SpaceX-3 cargo resupply mission, due to launch March 16th from Cape Canaveral Air Force Station in Florida.

These new legs, funded by NASA’s Human Exploration and Operations and Space Technology mission directorates, will provide R2 the mobility it needs to help with regular and repetitive tasks inside and outside the space station. The goal is to free up the crew for more critical work, including scientific research.

NASA looks for Asteroid candidates for Redirect Mission to the Moon

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One year ago, on February 15th, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth’s atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb.

Tracking near-Earth asteroids has been a significant endeavor for NASA and the broader astronomical community, which has discovered 10,713 known near-Earth objects to date.

This concept image shows an astronaut preparing to take samples from the captured asteroid after it has been relocated to a stable orbit in the Earth-moon system. Hundreds of rings are affixed to the asteroid capture bag, helping the astronaut carefully navigate the surface.

NASA scientists use new Technique to examine meteor, comet materials for components of Life

 

Written by Bill Steigerwald
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life.

Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life.

Researchers have analyzed carbon-rich meteorites (carbonaceous chondrites) and found amino acids, which are used to make proteins.

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has three new discoveries since reactivation

 

Written by Whitney Clavin/DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In its first 25 days of operations, the newly reactivated NEOWISE mission has detected 857 minor bodies in our solar system, including 22 near-Earth objects (NEOs) and four comets. Three of the NEOs are new discoveries; all three are hundreds of meters in diameter and dark as coal.

The mission has just passed its post-restart survey readiness review, and the project has verified that the ability to measure asteroid positions and brightness is as good as it was before the spacecraft entered hibernation in early 2011.

More than 100 asteroids were captured in this view from NASA's Wide-field Infrared Survey Explorer, or WISE, during its primary all-sky survey. (NASA/JPL-Caltech/UCLA)

NASA’s NEOWISE Spacecraft discovers it’s first new Asteroid since being reactivated

 

Written by DC Agle / Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen asteroid — its first such discovery since coming out of hibernation last year.

NEOWISE originally was called the Wide-field Infrared Survey Explorer (WISE), which had made the most comprehensive survey to date of asteroids and comets. The spacecraft was shut down in 2011 after its primary mission was completed.

The six red dots in this composite picture indicate the location of the first new near-Earth asteroid seen by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) since the spacecraft came out of hibernation in December 2013. The asteroid, called 2013 YP139, is the first of hundreds of space-rock discoveries expected during its renewed mission. The inset shows a zoomed-in view of one of the detections of 2013 YP139.

NASA’s Wide-Field Infrared Survey Explorer (WISE) takes image of dying star

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In an unexpected juxtaposition of cosmic objects that are actually quite far from each other, a newly released image from NASA’s Wide-Field Infrared Survey Explorer (WISE) shows a dying star, called the Helix nebula, surrounded by the tracks of asteroids. The nebula is far outside our solar system, while the asteroid tracks are inside our solar system.

The portrait, discovered by chance in a search for asteroids, comes at a time when the mission’s team is celebrating its fourth launch anniversary — and new lease on life.

NASA’s Deep Space Network celebrates 50 years of operation

 

Written by David Israel
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Deep Space Network, the world’s largest and most powerful communications system for “talking to” spacecraft, will reach a milestone on December 24th: the 50th anniversary of its official creation.

Over the past 50 years, antennas of the Deep Space Network (DSN) have communicated with just about every mission that has gone to the moon or beyond. The historic communiqués include “That’s one small step for man. One giant leap for mankind”; numerous encounters with the outer planets of our solar system; images taken by rovers exploring Mars; and the data confirming that NASA’s Voyager spacecraft had finally entered interstellar space.

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), a spacecraft that made the most comprehensive survey to date of asteroids and comets, has returned its first set of test images in preparation for a renewed mission.

NEOWISE discovered more than 34,000 asteroids and characterized 158,000 throughout the solar system during its prime mission in 2010 and early 2011.

NASA’s Mars Reconnaissance Orbiter shows seasonally changing surface near Mar’s equator

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Reconnaissance Orbiter has revealed to scientists slender dark markings — possibly due to salty water – that advance seasonally down slopes surprisingly close to the Martian equator.

“The equatorial surface region of Mars has been regarded as dry, free of liquid or frozen water, but we may need to rethink that,” said Alfred McEwen of the University of Arizona in Tucson, principal investigator for the Mars Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) camera.

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows how the appearance of dark markings on Martian slope changes with the seasons. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Wide-field Infrared Survey Explorer data used to bring Galaxies out of Hiding

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s WISE mission has released a new and improved atlas and catalog brimming with data on three-quarters of a billion objects detected during two full scans of the sky.

WISE, which stands for Wide-field Infrared Survey Explorer, scanned the entire sky in infrared light in 2010, snapping a dozen pictures of every star and galaxy. By October of that year, the spacecraft ran out of the coolant needed to chill some of its heat-seeking detectors. NASA then decided to fund a second scan of the sky to look for asteroids and comets, in a project called NEOWISE.

The new AllWISE catalog will bring distant galaxies that were once invisible out of hiding, as illustrated in this image.
