NASA’s Kepler Space Telescope discovers first Earth size planet orbiting another Star in the “Habitable Zone”

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting in the “habitable zone” of another star. The planet, named “Kepler-186f” orbits an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky Way galaxy.

The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

The “habitable zone” is defined as the range of distances from a star where liquid water might pool on the surface of an orbiting planet.

NASA’s AIM spacecraft data shows Teleconnections in Earth’s Atmosphere linking Climate and Weather across the Globe

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Earth’s poles are separated by four oceans, six continents and more than 12,000 nautical miles.

Turns out, that’s not so far apart.

New data from NASA’s AIM spacecraft have revealed “teleconnections” in Earth’s atmosphere that stretch all the way from the North Pole to the South Pole and back again, linking weather and climate more closely than simple geography would suggest.

Department of Defense releases Estimated Impacts of Sequestration-Level Funding Report

 

United States Department of Defense - DoDWashington, D.C. – On Tuesday, April 15th, 2014, the Department of Defense released a report that documents the damaging cuts to military forces, modernization, and readiness that will be required if defense budgets are held at sequester-levels in the years beyond fiscal 2015.  This report fulfills a commitment made by Secretary Chuck Hagel to provide details on the effects of these undesirable budget cuts.

As the report says, sequester level budgets would result in continued force-level cuts across the military services.

The Army would be reduced to 420,000 active duty soldiers along with 315,000 in the Guard and 185,000 in the Reserve. «Read the rest of this article»

NASA announces that SpaceX Dragon Cargo Spacecraft to launch Monday as scheduled

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – International Space Station Program officials, the international partners and representatives of SpaceX agreed Sunday to proceed with Monday’s scheduled launch of the SpaceX Falcon 9 rocket and its Dragon cargo craft on the company’s third commercial resupply mission to the orbital laboratory.

After a series of meetings and reviews of procedures, flight controllers, engineers and managers concluded that the SpaceX-3 mission could be conducted as planned without violating any launch commit criteria despite the loss Friday of a backup computer command relay box called a multiplexer/demultiplexer (MDM) that resides in the station’s S0 truss.

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A team of about 20 working at NASA’s Jet Propulsion Laboratory in Pasadena, CA, through the lab’s Phaeton early-career-hire program, led the development of the Optical Payload for Lasercomm Science (OPALS) investigation, which is preparing for an April 14th launch to the International Space Station aboard the SpaceX-3 mission.

The goal? NASA’s first optical communication experiment on the orbital laboratory.

NASA to conduct long term space flight experiment on Twins

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Consider a pair of brothers, identical twins. One gets a job as an astronaut and rockets into space. The other gets a job as an astronaut, too, but on this occasion he decides to stay home. After a year in space, the traveling twin returns home and they reunite.

Are the identical twins still … identical?

NASA is about to find out.

NASA says researchers use Microgravity Environment aboard International Space Station to better understand Fungi

 

Written by Laura Niles
International Space Station Program Science Office and Public Affairs Office

NASA - National Aeronautics and Space AdministrationWashington, D.C. – You may not recognize it by name, but if you have ever had a child with a diaper rash, that child was likely a host to Candida albicans (C. albicans). This unwelcome “guest” can be hard to control, as it can potentially lead to serious illness in humans with weakened immune systems.

During an investigation dubbed “Microbe,” using the unique microgravity environment aboard space shuttle Atlantis on an International Space Station mission, researchers at the Arizona State University (ASU) in Tempe gained a better understanding of these prevalent fungi.

Group Activation Pack cylinders similar to these, pictured within the Commercial Generic Bioprocessing Apparatus, were used to study the fungal pathogen C. albicans aboard space shuttle Atlantis. (NASA)

NASA’s Mars Curiosity rover stops to survey next Observations area

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – On Wednesday, NASA’s Curiosity Mars rover drove the last 98 feet feet (30 meters) needed to arrive at a site planned since early 2013 as a destination for studying rock clues about ancient environments that may have been favorable for life.

The rover reached a vantage point for its cameras to survey four different types of rock intersecting in an area called “the Kimberley,” after a region of western Australia.

NASA's Curiosity Mars rover recorded this view of various rock types at waypoint called "the Kimberley" shortly after arriving at the location on April 2, 2014. (NASA/JPL-Caltech)

NASA’s Cassini spacecraft data reveals Saturn’s moon Enceladus has underground Ocean

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. -  Evidence that Saturn’s moon Enceladus harbors a large underground ocean has been uncovered by NASA’s Cassini spacecraft and Deep Space Network, furthering scientific interest in the moon as a potential home to extraterrestrial microbes.

Researchers theorized the presence of an interior reservoir of liquid water in 2005 when Cassini discovered water vapor and ice spewing from vents near the moon’s south pole. New data on the moon’s gravity field reported in the April 4th, 2014, edition of the journal Science strengthen the case for an ocean hidden inside Enceladus.

This diagram illustrates the possible interior of Saturn's moon Enceladus based on a gravity investigation by NASA's Cassini spacecraft and NASA's Deep Space Network, reported in April 2014.
