NASA’s Mars Curiosity Rover discovers Nitrogen on Mars

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA’s Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments.

The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating. Nitrates are a class of molecules that contain nitrogen in a form that can be used by living organisms. The discovery adds to the evidence that ancient Mars was habitable for life.

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Lunar Reconnaissance Orbiter (LRO) acquired images of the lunar surface before and after the largest recorded explosion occurred on the surface.

On March 17th, 2013, an object the size of a small boulder hit the surface in Mare Imbrium and exploded in a flash of light nearly 10 times as bright as anything ever recorded before.

This bright flash was recorded by researchers at NASA’s Marshall Space Flight Center in Huntsville, AL with coordinates 20.6°N, 336.1°E.

NASA’s Magnetospheric Multiscale Probe set to launch March 12th

 

Written by Karen C. Fox
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – The Magnetospheric Multiscale, or MMS, mission is scheduled to launch into space on March 12th, 2015. The mission consists of four spacecraft to observe a phenomenon called magnetic reconnection — which doesn’t happen naturally on Earth all that often, but is a regular occurrence in space.

At the heart of magnetic reconnection is a fundamental physics process in which magnetic field lines come together and explosively realign, often sending the particles in the area flying off near the speed of light.

Solar flares – such as this one captured by NASA's SDO on July 12, 2012, are initiated by a phenomenon called magnetic reconnection. (NASA/SDO)

NASA’s Soil Moisture Active Passive (SMAP) observatory completes instruments test

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Fresh off the recent successful deployment of its 20-foot (6-meter) reflector antenna and associated boom arm, NASA’s new Soil Moisture Active Passive (SMAP) observatory has successfully completed a two-day test of its science instruments.

The observatory’s radar and radiometer instruments were successfully operated for the first time with SMAP’s antenna in a non-spinning mode on February 27th and 28th.

The test was a key step in preparation for the planned spin-up of SMAP’s antenna to approximately 15 revolutions per minute in late March.

The test was performed with SMAP's antenna in a non-spinning mode, which limits measurement swath widths to 25 miles (40 kilometers). (NASA/JPL-Caltech; NASA Goddard Space Flight Center)

NASA Scientists recreate Building Blocks of Life by simulating Outer Space Environment

 

Written by Ruth Marlaire
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces these essential ingredients of life.

Pyrimidine is a ring-shaped molecule made up of carbon and nitrogen and is the central structure for uracil, cytosine, and thymine, which are all three part of a genetic code found in ribonucleic (RNA) and deoxyribonucleic acids (DNA). RNA and DNA are central to protein synthesis, but also have many other roles.

NASA’s Wide-field Infrared Survey Explorer (WISE) discovers stars at the edge of the Milky Way Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers using data from NASA’s Wide-field Infrared Survey Explorer, or WISE, have found a cluster of stars forming at the very edge of our Milky Way galaxy.

“A stellar nursery in what seems to be the middle of nowhere is quite surprising,” said Peter Eisenhardt, the project scientist for the WISE mission at NASA’s Jet Propulsion Laboratory in Pasadena, California. “But surprises turn up when you look everywhere, as the WISE survey did.”

The newfound young star clusters lie thousands of light-years below the plane of our Milky Way galaxy, a flat spiral disk seen in this artist's conception. If alien lifeforms were to develop on planets orbiting these stars, they would have views of a portion, or all, of the galactic disk. (NASA/JPL-Caltech)

NASA’s Mars Curiosity Rover takes powder sample from rock at Telegraph Peak

 

Written by Guy Webster
NASA’ Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover used its drill on Tuesday, February 24th to collect sample powder from inside a rock target called “Telegraph Peak.” The target sits in the upper portion of “Pahrump Hills,” an outcrop the mission has been investigating for five months.

The Pahrump Hills campaign previously drilled at two other sites. The outcrop is an exposure of bedrock that forms the basal layer of Mount Sharp. Curiosity’s extended mission, which began last year after a two-year prime mission, is examining layers of this mountain that are expected to hold records of how ancient wet environments on Mars evolved into drier environments.

This hole, with a diameter slightly smaller than a U.S. dime, was drilled by NASA's Curiosity Mars rover into a rock target called "Telegraph Peak." (NASA/JPL-Caltech/MSSS)

NASA - National Aeronautics and Space AdministrationPasadena, CA – Over the past 12 months NASA has added five missions to its orbiting Earth-observing fleet – the biggest one-year increase in more than a decade. NASA scientists will discuss early observations from the new missions and their current status during a media teleconference at 11:00am PST (2:00pm EST) Thursday, February 26th.

New views of global carbon dioxide, rain and snowfall, ocean winds, and aerosol particles in the atmosphere will be presented during the briefing.

NASA’s Terra Satellite takes image of Eastern United States under Arctic Freeze

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Terra satellite captured an image of the snow-covered eastern U.S. that looks like the states have been sitting in a freezer. In addition to the snow cover, Arctic and Siberian air masses have settled in over the Eastern U.S. triggering many record low temperatures in many states.

On February 19th at 16:40 UTC (11:40am EST), the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA’s Terra satellite captured a picture of the snowy landscape.

NASA monitors Frigid Temperatures moving across Eastern United States

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Some of the coldest air of the 2014-2015 winter season was settling over the eastern two-thirds of the U.S. on February 13th, 2015. That Arctic air mass brought wind chills from below zero to the single numbers from the Midwest to the Mid-Atlantic.

Despite the cold on the surface, infrared NASA satellite imagery revealed even colder temperatures in cloud tops associated with the air mass.

NOAA’s GOES-East satellite provided a visible and infrared picture of the clouds associated with the Arctic air mass, as they stretched from the eastern Dakotas to the Mid-Atlantic region.

This false-colored infrared image from the AIRS instrument aboard NASA's Aqua satellite at 7:29 UTC (2:29 a.m. EST) shows cloud top temperatures over New York, Vermont, and New Hampshire near 245K/-28C/-18F (greenish to blue shading). (NASA JPL, Ed Olsen)
