NASA’s Mars Curiosity rover discovers smooth Iron-Nickel Meteorite on Mars

NASA - National Aeronautics and Space AdministrationPasadena, CA – Laser-zapping of a globular, golf-ball-size object on Mars by NASA’s Curiosity rover confirms that it is an iron-nickel meteorite fallen from the Red Planet’s sky.

Iron-nickel meteorites are a common class of space rocks found on Earth, and previous examples have been seen on Mars, but this one, called “Egg Rock,” is the first on Mars examined with a laser-firing spectrometer. To do so, the rover team used Curiosity’s Chemistry and Camera (ChemCam) instrument.

The dark, smooth-surfaced rock at the center of this Oct. 30, 2016, image from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover was examined with laser pulses and confirmed to be an iron-nickel meteorite. It is about the size of a golf ball. (Credit: NASA/JPL-Caltech/MSSS)

NASA Study finds patterns in the occurrence of Global Dust Storms on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Global dust storms on Mars could soon become more predictable — which would be a boon for future astronauts there — if the next one follows a pattern suggested by those in the past.

A published prediction, based on this pattern, points to Mars experiencing a global dust storm in the next few months. “Mars will reach the midpoint of its current dust storm season on October 29th of this year. Based on the historical pattern we found, we believe it is very likely that a global dust storm will begin within a few weeks or months of this date,” James Shirley, a planetary scientist at NASA’s Jet Propulsion Laboratory, Pasadena, California.

Two 2001 images from the Mars Orbiter Camera on NASA's Mars Global Surveyor orbiter show a dramatic change in the planet's appearance when haze raised by dust-storm activity in the south became globally distributed. The images were taken about a month apart. (NASA/JPL-Caltech/MSSS)

NASA, Japan Aerospace Exploration Agency partner to increase research abilities on International Space Station

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A new program for research cooperation on the International Space Station will enable JAXA (Japan Aerospace Exploration Agency) and NASA to encourage researchers and entities from both countries to mutually utilize experiment hardware between the U.S. and Japanese Experiment Module (JEM, or Kibo, which means “Hope” in Japanese).

The Japan-U.S. Open Platform Partnership Program was announced by the governments of the U.S. and Japan in December 2015, and will run through at least 2024.

The Japanese Experiment Module (JEM), includes an external platform for payloads, an airlock and a robotic arm for deploying payloads. The module is called “Kibo,” which means “hope” in Japanese. (NASA)

NASA research helps develop Artificial Intelligence Technology that may one day help First Responders in the Field

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Firefighters have only their wits and five senses to rely on inside a burning building. But research developed in part by NASA’s Jet Propulsion Laboratory, Pasadena, California, may change that, introducing artificial intelligence (AI) that could collect data on temperatures, gases and other danger signals and guide a team of first responders safely through the flames.

AUDREY, the Assistant for Understanding Data through Reasoning, Extraction, and sYnthesis, has received the Undersecretary’s Award for Collaboration from the Department of Homeland Security (DHS) in recognition of its joint development by JPL and DHS.

NASA’s Juno Spacecraft takes first pictures from Jupiter Orbit

 

Written by DC Agle / Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The JunoCam camera aboard NASA’s Juno mission is operational and sending down data after the spacecraft’s July 4th arrival at Jupiter. Juno’s visible-light camera was turned on six days after Juno fired its main engine and placed itself into orbit around the largest planetary inhabitant of our solar system. The first high-resolution images of the gas giant Jupiter are still a few weeks away.

“This scene from JunoCam indicates it survived its first pass through Jupiter’s extreme radiation environment without any degradation and is ready to take on Jupiter,” said Scott Bolton, principal investigator from the Southwest Research Institute in San Antonio. “We can’t wait to see the first view of Jupiter’s poles.”

This color view from NASA's Juno spacecraft is made from some of the first images taken by JunoCam after the spacecraft entered orbit around Jupiter on July 5th (UTC). (NASA/JPL-Caltech/SwRI/MSSS)

American Heart Association reports Hispanics/Latinos at higher risk for Cardiac Dysfunction, Heart Failure

 

American Heart Association Rapid Access Journal Report

American Heart AssociationDallas, TX – Hispanics/Latinos have higher rates of cardiac dysfunction but are rarely aware they have the heart-pumping problem that can lead to heart failure, according to new research in the American Heart Association’s journal Circulation: Heart Failure.

Researchers found that about half of the 1,818 adults in their study of middle-aged and older Hispanics/Latinos had cardiac dysfunction, yet fewer than 1 in 20 participants knew they had a problem.

NASA says Caltech’s CHIMERA instrument to examine Objects in Kuiper Belt

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – At the Palomar Observatory near San Diego, astronomers are busy tinkering with a high-tech instrument that could discover a variety of objects both far from Earth and closer to home.

The Caltech HIgh-speed Multi-color camERA (CHIMERA) system is looking for objects in the Kuiper Belt, the band of icy bodies beyond the orbit of Neptune that includes Pluto. It can also detect near-Earth asteroids and exotic forms of stars. Scientists at NASA’s Jet Propulsion Laboratory and the California Institute of Technology, both in Pasadena, are collaborating on this instrument.

The CHIMERA instrument is located at the Hale Telescope at the Palomar Observatory near San Diego, California. (Gregg Hallinan)

NASA prepares Orion spacecraft and Space Launch System rocket for first test flight

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA is hard at work building the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems needed to send astronauts into deep space. The agency is developing the core capabilities needed to enable the journey to Mars.

Orion’s first flight atop the SLS will not have humans aboard, but it paves the way for future missions with astronauts. Ultimately, it will help NASA prepare for missions to the Red Planet. During this flight, currently designated Exploration Mission-1 (EM-1), the spacecraft will travel thousands of miles beyond the moon over the course of about a three-week mission.

NASA¹s Space Launch System rocket will launch with Orion atop it from Launch Complex 39B at NASA¹s modernized spaceport at Kennedy Space Center in Florida. (NASA)

NASA Study compares two types of Southern California Fires

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new University of California/NASA study finds Southern California autumn wildfires driven by Santa Ana winds have been 10 times as costly in the past 20 years as summer wildfires, even though both types of fires have consumed about the same total acreage.

Both types of fires are predicted to increase by midcentury, but non-Santa Ana fires are expected to increase more.

The research could assist policymakers and response agencies in better allocating firefighting resources in the future.

An October 2007 image, left, of Southern California wildfires shows how offshore Santa Ana winds control these events. Wind is less likely to dominate summer fires like the 2009 Station Fire, right. Images from the Moderate Resolution Imaging Spectrometer on NASA's Aqua satellite. (NASA)
