NASA to Chronicle Close Earth Flyby of Asteroid

on Thursday, 14 February 2013. Posted in Space, Sci/Tech

At the time of its closest approach to Earth at approximately 11:25 a.m. PST (2:25 p.m. EST / 19:25 UTC), the asteroid will be about 17,150 miles (27,600 kilometers) above Earth's surface.

NASA to Chronicle Close Earth Flyby of Asteroid

NASA Television will provide commentary starting at 11 a.m. PST (2 p.m. EST) on Friday, Feb. 15, during the close, but safe, flyby of a small near-Earth asteroid named 2012 DA14. NASA places a high priority on tracking asteroids and protecting our home planet from them. This flyby will provide a unique opportunity for researchers to study a near-Earth object up close.

NASA Associate Administrator John Grunsfeld: "This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August, another proud day for America."

NASA Curiosity Rover Collects First Martian Bedrock Sample

NASA's Curiosity rover has, for the first time, used a drill carried at the end of its robotic arm to bore into a flat, veiny rock on Mars and collect a sample from its interior. This is the first time any robot has drilled into a rock to collect a sample on Mars.

Curator Stephen Godfrey: "This is an armored type of dinosaur that had spikes all over their body. The spikes consist of bones that were embedded in their skin."

Dinosaur Footprints at NASA Goddard Take Another Step

A grouping of 110 to 112 million-year-old dinosaur footprints pressed into mud from the Cretaceous Period have now been safely moved from their original setting on the grounds of NASA's Goddard Space Flight Center in Greenbelt, Md. Until further scientific study is possible, the footprints, now wrapped in protective material, will be stored on the Goddard campus.

NASA project scientist Paul Goldsmith: "This is another example of Herschel's versatility and sensitivity yielding important new results about star and planet formation."

Herschel Finds Past-Prime Star may be Making Planets

A star thought to have passed the age at which it can form planets may, in fact, be creating new worlds. The disk of material surrounding the surprising star called TW Hydrae may be massive enough to make even more planets than we have in our own solar system.

NASA Telescope Observes How Sun Stores and Releases Energy

Heliophysicist Jonathan Cirtain: "Seeing this for the first time is a major advance in understanding how our sun continuously generates the vast amount of energy needed to heat its atmosphere."

NASA Telescope Observes How Sun Stores and Releases Energy

A NASA suborbital telescope has given scientists the first clear evidence of energy transfer from the sun's magnetic field to the solar atmosphere or corona. This process, known as solar braiding, has been theorized by researchers, but remained unobserved until now.

NASA's Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet.

NASA Mars Rover Preparing to Drill Into First Martian Rock

NASA's Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet. If the rock meets rover engineers' approval when Curiosity rolls up to it in coming days, it will become the first to be drilled for a sample during the Mars Science Laboratory mission.

NASA Rules Out Earth Impact in 2036 for Asteroid Apophis

on Friday, 11 January 2013. Posted in Space, Sci/Tech

Discovered in 2004, the asteroid, which is the size of three-and-a-half football fields, gathered the immediate attention...when initial calculations of its orbit indicated a 2.7 percent possibility of an Earth impact during a close flyby in 2029.

NASA Rules Out Earth Impact in 2036 for Asteroid Apophis

NASA scientists at the agency's Jet Propulsion Laboratory in Pasadena, Calif., effectively have ruled out the possibility the asteroid Apophis will impact Earth during a close flyby in 2036. The scientists used updated information obtained by NASA-supported telescopes in 2011 and 2012, as well as new data from the time leading up to Apophis' distant Earth flyby yesterday (Jan. 9).

Sensenbrenner Questions Administration’s Shortsighted NASA Policy

on Friday, 14 December 2012. Posted in Space, Sci/Tech, Opinion, Letter From Congress

Rep. Jim Sensenbrenner: "Now by cancelling the Constellation Program, NASA has lost international partners who supported a mission to the Moon. President Obama took a “been there, done that” approach. But we haven’t been there in 40 years..."

Sensenbrenner Questions Administration’s Shortsighted NASA Policy

By the office of Congressman Sensenbrenner 

During a Science Committee hearing today [December 12, 2012], Congressman Sensenbrenner questioned the Obama Administration’s short sighted NASA policy because it threatens America’s ability to recruit and train a future generation of scientists and engineers.

Astronomers Catch Jet from Binge-Eating Black Hole

on Thursday, 13 December 2012. Posted in Space, Sci/Tech

"The discovery of jets tells us that this particular ULX is a typical stellar remnant about 10 times the mass of the sun, swallowing as much material as it possibly can," said Matthew Middleton, astronomer at the Anton Pannekoek Astronomical Institute.

Astronomers Catch Jet from Binge-Eating Black Hole

Back in January, a new X-ray source flared and rapidly brightened in the Andromeda galaxy (M31), located 2.5 million light-years away. Classified as an ultraluminous X-ray source (ULX), the object is only the second ever seen in M31 and became the target of an intense observing campaign by orbiting X-ray telescopes -- including NASA's Swift -- and radio observatories on the ground. These efforts resulted in the first detection of radio-emitting jets from a stellar-mass black hole outside our own galaxy.

Cassini Spots Mini Nile River on Saturn Moon

on Thursday, 13 December 2012. Posted in Space, Sci/Tech

"Titan is the only place we've found besides Earth that has a liquid in continuous movement on its surface," said Steve Wall, the radar deputy team lead, based at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Cassini Spots Mini Nile River on Saturn Moon

Scientists with NASA's Cassini mission have spotted what appears to be a miniature, extraterrestrial likeness of Earth's Nile River: a river valley on Saturn's moon Titan that stretches more than 200 miles (400 kilometers) from its "headwaters" to a large sea. It is the first time images have revealed a river system this vast and in such high resolution anywhere other than Earth.

NASA's Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space.

Solar Minimum; Solar Maximum

on Tuesday, 27 November 2012. Posted in Space, Sci/Tech

The journey toward solar maximum is evident in current images of the sun, showing a marked difference from those of 2010, with bright active regions dotted around the star.

Solar Minimum; Solar Maximum

The sun goes through a natural solar cycle approximately every 11 years. The cycle is marked by the increase and decrease of sunspots -- visible as dark blemishes on the sun's surface, or photosphere. The greatest number of sunspots in any given solar cycle is designated as "solar maximum." The lowest number is "solar minimum."

Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe

on Wednesday, 26 September 2012. Posted in Space, Sci/Tech

Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe.

Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe

Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon.
