NASA’s Hubble Space Telescope used to create High-Resolution Ultraviolet-Light survey of nearby Galaxies

 

NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Capitalizing on the unparalleled sharpness and spectral range of NASA’s Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.

The researchers combined new Hubble observations with archival Hubble images for 50 star-forming spiral and dwarf galaxies in the local universe, offering a large and extensive resource for understanding the complexities of star formation and galaxy evolution.

The project, called the Legacy ExtraGalactic UV Survey (LEGUS), has amassed star catalogs for each of the LEGUS galaxies and cluster catalogs for 30 of the galaxies, as well as images of the galaxies themselves.

These six images represent the variety of star-forming regions in nearby galaxies. The galaxies are part of the Hubble Space Telescope's Legacy ExtraGalactic UV Survey (LEGUS), the sharpest, most comprehensive ultraviolet-light survey of star-forming galaxies in the nearby universe.

NASA to launch three CubeSat satellites on next International Space Station resupply mission

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – This weekend, when the next cargo resupply mission to the International Space Station lifts off from NASA Wallops Flight Facility in Virginia, it will be carrying among its supplies and experiments three cereal box-sized satellites that will be used to test and demonstrate the next generation of Earth-observing technology.

NASA has been increasing its use of CubeSats — small satellites based on several configurations of approximately 4 x 4 x 4-inch cubes — to put new technologies in orbit where they can be tested in the harsh environment of space before being used as part of larger satellite missions or constellations of spacecraft.

NASA’s Mars Curiosity Rover to use new technique to get back to drilling

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity rover could soon be drilling rocks on Mars again.

Engineers have been working for the past year to restore the rover’s full drilling capabilities, which were hampered in 2016 due to a mechanical problem. Later this weekend, they’ll be adding percussion to a new technique already in use on Mars.

This new technique is called Feed Extended Drilling, or FED. It lets Curiosity drill more like the way a person would at home, using the force of its robotic arm to push its drill bit forward as it spins. The new version of FED adds a hammering force to the drill bit.

NASA satellite observations reveal Freshwater locations changing around the Earth

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In a first-of-its-kind study, scientists have combined an array of NASA satellite observations of Earth with data on human activities to map locations where freshwater is changing around the globe and why.

The study, published today in the journal Nature, finds that Earth’s wet land areas are getting wetter and dry areas are getting drier due to a variety of factors, including human water management, climate change and natural cycles.

A team led by Matt Rodell of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, used 14 years of observations from the U.S./German-led Gravity Recovery and Climate Experiment (GRACE) spacecraft mission to track global trends in freshwater in 34 regions around the world.

NASA’s Mars Cube One takes photo of Earth and Moon

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Voyager 1 took a classic portrait of Earth from several billion miles away in 1990. Now a class of tiny, boxy spacecraft, known as CubeSats, have just taken their own version of a “pale blue dot” image, capturing Earth and its moon in one shot.

NASA set a new distance record for CubeSats on May 8th when a pair of CubeSats called Mars Cube One (MarCO) reached 621,371 miles (1 million kilometers) from Earth. One of the CubeSats, called MarCO-B (and affectionately known as “Wall-E” to the MarCO team) used a fisheye camera to snap its first photo on May 9th. That photo is part of the process used by the engineering team to confirm the spacecraft’s high-gain antenna has properly unfolded.

The first image captured by one of NASA's Mars Cube One (MarCO) CubeSats. The image, which shows both the CubeSat's unfolded high-gain antenna at right and the Earth and its moon in the center, was acquired by MarCO-B on May 9. (NASA/JPL-Caltech)

Reexamination of NASA Galileo orbiter data yields new evidence of Plumes from Jupiter’s moon Europa

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence that the moon’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.

Data collected by NASA’s Galileo spacecraft in 1997 were put through new and advanced computer models to untangle a mystery — a brief, localized bend in the magnetic field — that had gone unexplained until now.

NASA looks to use Carbon Nanotube Technology for Spaceflight Applications

 

Written by Lori Keesey
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – An ultra-dark coating comprised of nearly invisible shag rug-like strands made of pure carbon is proving to be highly versatile for all types of spaceflight applications.

In the most recent application of the carbon-nanotube coating, optical engineer John Hagopian, a contractor at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Goddard scientist Lucy Lim are growing an array of miniscule, button-shaped bumps of multi-walled nanotubes on a silicon wafer.

John Hagopian (left) collaborated with instrument scientist Lucy Lim to develop a new instrument that relies on carbon nanotubes to provide the electrons needed to excite minerals contained in an extraterrestrial sample. Larry Hess (right) patterns all the leads and patches where the catalyst for growing nanotubes is deposited. (NASA's Goddard Space Flight Center/Bill Hrybyk)

NASA discovers X-ray Pulsar with fastest Orbit ever recorded

 

Written by Jeanette Kazmierczak
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Scientists analyzing the first data from the Neutron star Interior Composition Explorer (NICER) mission have found two stars that revolve around each other every 38 minutes — about the time it takes to stream a TV drama.

One of the stars in the system, called IGR J17062–6143 (J17062 for short), is a rapidly spinning, superdense star called a pulsar. The discovery bestows the stellar pair with the record for the shortest-known orbital period for a certain class of pulsar binary system.

The data from NICER also show J17062’s stars are only about 186,000 miles (300,000 kilometers) apart, less than the distance between Earth and the Moon.

The stars of IGR J17062–6143, illustrated here, circle each other every 38 minutes, the fastest-known orbit for a binary system containing an accreting millisecond X-ray pulsar. As they revolve, a superdense pulsar pulls gas from a lightweight white dwarf. The two stars are so close they would fit between Earth and the Moon. (NASA’s Goddard Space Flight Center)
