Pasadena, CA – Scientists working with NASA’s 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of asteroid 2004 BL86. The images show the asteroid, which made its closest approach today (January 26th, 2015) at 8:19am PST (10:19am CST) at a distance of about 745,000 miles (1.2 million kilometers, or 3.1 times the distance from Earth to the moon), has its own small moon.
The 20 individual images used in the movie were generated from data collected at Goldstone on January 26th, 2015. They show the primary body is approximately 1,100 feet (325 meters) across and has a small moon approximately 230 feet (70 meters) across.

Pasadena, CA – A new NASA satellite that will peer into the topmost layer of Earth’s soils to measure the hidden waters that influence our weather and climate is in final preparations for a January 29th dawn launch from California.
The Soil Moisture Active Passive (SMAP) mission will take the pulse of a key measure of our water planet: how freshwater cycles over Earth’s land surfaces in the form of soil moisture.
The mission will produce the most accurate, highest-resolution global maps ever obtained from space of the moisture present in the top 2 inches (5 centimeters) of Earth’s soils.
NASA’s Hubble Space Telescope takes image of Pillars of Creation that shows possible destructive side
Written by Tony Phillips
Washington, D.C. – Although NASA’s Hubble Space Telescope has taken many breathtaking images of the universe, one snapshot stands out from the rest: the iconic view of the so-called “Pillars of Creation.”
The jaw-dropping photo, taken in 1995, revealed never-before-seen details of three giant columns of cold gas bathed in the scorching ultraviolet light from a cluster of young, massive stars in a small region of the Eagle Nebula, or M16.
In celebration of its upcoming 25th anniversary in April, Hubble has revisited the famous pillars, providing astronomers with a sharper and wider view. Although the original image was dubbed the Pillars of Creation, the new image hints that they are also “pillars of destruction.”
NASA’s Wide-field Infrared Survey Explorer (WISE) data analyzed by Volunteer Disk Detectives finds possible Planetary Habitats
Written by Francis Reddy
Greenbelt, MD – A NASA-sponsored website designed to crowdsource analysis of data from the agency’s Wide-field Infrared Survey Explorer (WISE) mission has reached an impressive milestone.
In less than a year, citizen scientists using DiskDetective.org have logged 1 million classifications of potential debris disks and disks surrounding young stellar objects (YSO). This data will help provide a crucial set of targets for future planet-hunting missions.

Pasadena, CA – It’s active. It’s passive. And it’s got a big, spinning lasso.
Scheduled for launch on January 29th, 2015, NASA’s Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth’s soils with an unprecedented accuracy and resolution. The instrument’s three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.
Remote sensing instruments are called “active” when they emit their own signals and “passive” when they record signals that already exist.

Greenbelt, MD – Severe weather in the form of tornadoes is not something people expect on Christmas week but a storm system on December 23rd brought tornadoes to Mississippi, Georgia and Louisiana. As the storm moved, NASA’s RapidScat captured data on winds while NOAA’s GOES satellite tracked the movement of the system.
NASA’s RapidScat instrument flies aboard the International Space Station and captured a look at some of the high winds from the storms that brought severe weather to the U.S. Gulf Coast on December 23rd. In addition, an animation of images from NOAA’s GOES-East satellite showed the movement of those storms and other weather systems from Canada to South America from December 21st to 24th.

Pasadena, CA – For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun.
NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy X-rays.
“NuSTAR will give us a unique look at the sun, from the deepest to the highest parts of its atmosphere,” said David Smith, a solar physicist and member of the NuSTAR team at University of California, Santa Cruz.
NASA’s Mars Curiosity rover detects organic chemical in atmosphere and organic molecules in rock powder on Mars
Written by Guy Webster
Pasadena, CA – NASA’s Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill.
“This temporary increase in methane — sharply up and then back down — tells us there must be some relatively localized source,” said Sushil Atreya of the University of Michigan, Ann Arbor, a member of the Curiosity rover science team. “There are many possible sources, biological or non-biological, such as interaction of water and rock.”

Pasadena, CA – The Voyager 1 spacecraft has experienced three shock waves.
The most recent shock wave, first observed in February 2014, still appears to be going on.
One wave, previously reported, helped researchers determine that Voyager 1 had entered interstellar space.
The “tsunami wave” that NASA’s Voyager 1 spacecraft began experiencing earlier this year is still propagating outward, according to new results. It is the longest-lasting shock wave that researchers have seen in interstellar space.
Washington, D.C. – NASA and space agencies across the globe are opening up new possibilities for space exploration with missions to comets, asteroids, and other celestial bodies.
Following NASA, European Space Agency (ESA), and Indian Space Research Organisation (ISRO) spacecraft observations of the close flyby of Mars by comet Siding Spring in October, and the successful November landing of ESA’s Philae lander on comet 67P/Churyumov–Gerasimenko, the Japan Aerospace Exploration Agency (JAXA) successfully launched its Hayabusa2 mission on December 3rd to rendezvous with an asteroid, land a small probe plus three mini rovers on its surface, and then return samples to Earth.
