NASA to launch Expandable Habitat to International Space station

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA and Bigelow Aerospace are preparing to launch an expandable habitat module to the International Space Station this year. The agency joined Bigelow Thursday at its Las Vegas facility to mark completion of the company’s major milestones.

The Bigelow Expandable Activity Module, or BEAM, leverages key innovations in lightweight and compact materials, departing from a traditional rigid metallic structure. In its packed configuration aboard SpaceX’s Dragon spacecraft launched on a Falcon 9 rocket, the module will measure approximately 8 feet in diameter.

NASA’s Mars Curiosity rover uses arm to move sample rock powder to analyzing instrument

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover used its robotic arm Wednesday, March 11th, to sieve and deliver a rock-powder sample to an onboard instrument. The sample was collected last month before the team temporarily suspended rover arm movement pending analysis of a short circuit.

The Chemistry and Mineralogy (CheMin) analytical instrument inside the rover received the sample powder. This sample comes from a rock target called “Telegraph Peak,” the third target drilled during about six months of investigating the “Pahrump Hills” outcrop on Mount Sharp. With this delivery completed, the rover team plans to drive Curiosity away from Pahrump Hills in coming days.

This area at the base of Mount Sharp on Mars includes a pale outcrop, called "Pahrump Hills," that NASA's Curiosity Mars rover investigated from September 2014 to March 2015, and the "Artist's Drive" route toward higher layers of the mountain. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Cassini spacecraft reveals Ocean on Saturn’s moon Enceladus may have Hydrothermal Activity

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft has provided scientists the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities.

“These findings add to the possibility that Enceladus, which contains a subsurface ocean and displays remarkable geologic activity, could contain environments suitable for living organisms,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “The locations in our solar system where extreme environments occur in which life might exist may bring us closer to answering the question: are we alone in the universe.”

This cutaway view of Saturn's moon Enceladus is an artist's rendering that depicts possible hydrothermal activity that may be taking place on and under the seafloor of the moon's subsurface ocean, based on recently published results from NASA's Cassini mission. (NASA/JPL-Caltech)

NASA’s Mars Curiosity rover to begin using it’s arm again

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Managers of NASA’s Curiosity Mars rover mission expect to approve resumption of rover arm movements as early as next week while continuing analysis of what appears to be an intermittent short circuit in the drill.

A fluctuation in current on February 27th triggered a fault-protection response that immediately halted action by the rover during the mission’s 911th Martian day, or sol.

Since then, the rover team has avoided driving Curiosity or moving the rover’s arm, while engineers have focused on diagnostic tests. Science observations with instruments on the rover’s mast have continued, along with environmental monitoring by its weather station.

This March 4, 2015, image from the Navcam on NASA's Curiosity Mars rover shows the position in which the rover held its arm for several days after a transient short circuit triggered onboard fault-protection programming to halt arm activities on Feb. 27th. (NASA/JPL-Caltech/MSSS)

NASA’s Dawn spacecraft makes history as it begins orbit around Dwarf Planet Ceres

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000 kilometers) from Ceres when it was captured by the dwarf planet’s gravity at about 4:39am PST (7:39am EST) Friday.

Mission controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California received a signal from the spacecraft at 5:36am PST (8:36am EST) that Dawn was healthy and thrusting with its ion engine, the indicator Dawn had entered orbit as planned.

IRS gives Five Good Reasons why you should choose Direct Deposit

 

Internal Revenue Service - IRSWashington, D.C. – The best way to get your tax refund is by direct deposit.

You should deposit your refund directly into accounts in your own name, your spouse’s name or both. Don’t deposit it in accounts owned by others. Some banks require both spouses’ names on the account to deposit a tax refund from a joint return. Check with your bank for their direct deposit requirements.

Here are five good reasons to join the 84 million taxpayers who chose direct deposit last year. «Read the rest of this article»

NASA researchers study of Ionosphere may help improve GPS Communications

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – When you don’t know how to get to an unfamiliar place, you probably rely on a smart phone or other device with a Global Positioning System (GPS) module for guidance. You may not realize that, especially at high latitudes on our planet, signals traveling between GPS satellites and your device can get distorted in Earth’s upper atmosphere.

Researchers at NASA’s Jet Propulsion Laboratory, Pasadena, California, in collaboration with the University of New Brunswick in Canada, are studying irregularities in the ionosphere, a part of the atmosphere centered about 217 miles (350 kilometers) above the ground that defines the boundary between Earth and space.

NASA Earth science missions provide new insights into planet Earth

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Four new NASA Earth-observing missions are collecting data from space – with a fifth newly in orbit – after the busiest year of NASA Earth science launches in more than a decade.

On February 27th, 2014, NASA and the Japan Aerospace Exploration Agency (JAXA) launched the Global Precipitation Measurement (GPM) Core Observatory into space from Japan. GPM and the other new missions are making observations and providing new insights into global rain and snowfall, atmospheric carbon dioxide, ocean winds, clouds and tiny airborne particles called aerosols. Three of the new Earth missions are managed by NASA’s Jet Propulsion Laboratory, Pasadena, California.

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)
