NASA uses Satellite data to create Damage Maps of Nepal’s Earthquake

 

Written by Elizabeth Landau

NASA - National Aeronautics and Space AdministrationPasadena, CA – Nepal’s magnitude 7.8 Gorkha earthquake caused significant damage and loss of life in 2015. In natural disasters like this, it is critical to locate areas that are in the most need of assistance as fast as possible.

Quickly assessing and communicating where the hardest-hit areas are and prioritizing which regions or communities have the greatest need for first-response teams is difficult when a disaster unevenly devastates various parts of a large area. It helps to get a bigger-picture view of where the damage is located from a high vantage point: low-Earth orbit.

This image shows street-level photos in the Bhaktapur area of Nepal overlaid on a damage proxy map derived from data from COSMO-SkyMed satellites. The color gradation -- yellow to orange to red -- represents increasingly more significant change on the ground. (NASA/JPL-Caltech/Google/DigitalGlobe/CNES/Astrium/Amy MacDonald/Thornton Tomasetti)

NASA study will have 4 People living in an Isolated Habitat for 30 Days in preparation for long Space Missions

 

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – 4 people are living in an isolated habitat for 30 days. Why? Science!

This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house.

The Human Exploration Research Analog (HERA), formerly known as the Deep Space Habitat, was transferred from the JSC Engineering Directorate to HRP in FY2013. This unique modular three-story habitat was designed and created through a series of university competitions and was previously used in the Desert Research and Technology Studies in the Arizona desert.

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The latest self-portrait from NASA’s Curiosity Mars rover shows the car-size mobile laboratory beside a dark dune where it has been scooping and sieving samples of sand.

The new selfie combines 57 images taken by the Mars Hand Lens Imager (MAHLI) camera at the end of Curiosity’s arm on January 19th.

The rover has been investigating a group of active sand dunes for two months, studying how the wind moves and sorts sand particles on Mars. The site is part of Bagnold Dune Field, which lines the northwestern flank of Mars’ Mount Sharp.

This Jan. 19, 2016, self-portrait of NASA's Curiosity Mars rover shows the vehicle at "Namib Dune," where the rover's activities included scuffing into the dune with a wheel and scooping samples of sand for laboratory analysis. (NASA/JPL-Caltech/MSSS)

NASA’s Dawn Spacecraft photos reveal details of Dwarf Planet Ceres over 200 years since it’s discovery

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New Year’s Day, 1801, the dawn of the 19th century, was a historic moment for astronomy, and for a space mission called Dawn more than 200 years later. That night, Giuseppe Piazzi pointed his telescope at the sky and observed a distant object that we now know as Ceres.

Today, NASA’s Dawn mission allows us to see Ceres in exquisite detail. From the images Dawn has taken over the past year, we know Ceres is a heavily cratered body with diverse features on its surface that include a tall, cone-shaped mountain and more than 130 reflective patches of material that is likely salt. But on that fateful evening in 1801, Piazzi wasn’t sure what he was seeing when he noticed a small, faint light through his telescope.

Giuseppe Piazzi used this instrument, called a Ramsden Circle, to discover Ceres on January 1, 1801. The telescope is on display at the Palermo Observatory in Sicily. (NASA/JPL-Caltech/Palermo Observatory)

NASA Scientists help study the seas around Antarctica

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A team of scientists has launched a series of research flights over the remote seas surrounding Antarctica in an effort to better understand how much carbon dioxide the icy waters are able to lock away.

Called ORCAS, the field campaign will provide a rare look at how oxygen and carbon dioxide are exchanged between the air and the Southern Ocean. The campaign is led by the National Center for Atmospheric Research (NCAR). Michelle Gierach of NASA’s Jet Propulsion Laboratory, Pasadena, California, is a principal investigator, along with other scientists from a range of universities and research institutions.

NASA’s Mars Opportunity rover keeps busy during Martian Winter

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s senior Mars rover, Opportunity, worked through the lowest-solar-energy days of the mission’s seventh Martian winter, while using a diamond-toothed rock grinder and other tools in recent weeks to investigate clues about the Red Planet’s environmental history.

The modern Mars environment lent a hand, providing wind that removed some dust from Opportunity’s solar panels in the weeks before and after the Mars southern hemisphere’s winter solstice on January 2nd.

NASA’s Cassini Spacecraft to move into higher orbit around Saturn

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini mission is entering its next chapter with an orbital choreography meant to tilt the spacecraft’s orbit out of Saturn’s ringplane.

The second of five large propulsive maneuvers in this campaign took place on Saturday, January 23rd. Each maneuver in the series sets up a subsequent gravity-assist flyby of Saturn’s massive moon Titan, which reshapes the spacecraft’s orbit, sending it to increasingly higher inclination with respect to Saturn’s equator.

This is an artists concept of Cassini during the Saturn Orbit Insertion (SOI) maneuver, just after the main engine has begun firing. (NASA/JPL)

NASA Scientists study Galaxy Clusters to better understand Dark Matter

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Dark matter is a mysterious cosmic phenomenon that accounts for 27 percent of all matter and energy. Though dark matter is all around us, we cannot see it or feel it. But scientists can infer the presence of dark matter by looking at how normal matter behaves around it.

Galaxy clusters, which consist of thousands of galaxies, are important for exploring dark matter because they reside in a region where such matter is much denser than average. Scientists believe that the heavier a cluster is, the more dark matter it has in its environment. But new research suggests the connection is more complicated than that.

This image from NASA's Hubble Space Telescope shows the inner region of Abell 1689, an immense cluster of galaxies. Scientists say the galaxy clusters we see today have resulted from fluctuations in the density of matter in the early universe. (NASA/ESA/JPL-Caltech/Yale/CNRS)

NASA reports Caltech Researchers discover evidence of a new Planet, Planet 9

 

Written by Kimm Fesenmaier
California Institute of Technology

NASA - National Aeronautics and Space AdministrationPasadena, CA – Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system.

The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun.

The researchers, Konstantin Batygin and Mike Brown, discovered the planet’s existence through mathematical modeling and computer simulations but have not yet observed the object directly.

This artistic rendering shows the distant view from Planet Nine back towards the sun. The planet is thought to be gaseous, similar to Uranus and Neptune. Hypothetical lightning lights up the night side. (Caltech/R. Hurt (IPAC))

NASA reports Five Planets visible in the morning sky from now till February 20th

 

Written by Jane Platt
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – “When the moon is in the seventh house, and Jupiter aligns with Mars, then peace will guide the planets, and love will steer the stars.”

Well, it’s not quite like the song about the dawning of the Age of Aquarius, but our solar system is experiencing an uncommon lineup that should be quite a treat for sky-watchers. The solar system itself hasn’t changed — it’s just that the timing of the planets orbiting the sun puts them into a lineup that makes for good viewing by Earthlings.

Early risers have an opportunity to see five naked-eye planets in pre-dawn skies during late January and continuing through late February. (NASA/JPL-Caltech)
