NASA looks back at the July 2012 Solar Superstorm that just missed Earth

 

Written by Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news.

Two years ago, Earth experienced a close shave just as perilous, but most newspapers didn’t mention it. The “impactor” was an extreme solar storm, the most powerful in as much as 150+ years.

“If it had hit, we would still be picking up the pieces,” says Daniel Baker of the University of Colorado.

NASA’s prepares for Next Giant Leap, Mars and Beyond

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The first humans who will step foot on Mars are walking the Earth today. It was 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era.

We stand on a new horizon, poised to take the next giant leap—deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond.

NASA’s Johnson Space Center has Astronauts Test Tools Underwater for Asteroid Mission

 

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – NASA is planning to send astronauts to an asteroid in the 2020s, and preparations are already being made.

Stan Love and Steve Bowen have between them spent more than 62 hours in the vacuum of space on nine shuttle mission spacewalks, and they’re putting that experience to use here on Earth by helping engineers determine what astronauts will need on NASA’s next step toward Deep Space.

NASA’s Spitzer Space Telescope finds Asteroid candidate for Redirect Mission

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers using NASA’s Spitzer Space Telescope have measured the size of an asteroid candidate for NASA’s Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid.

The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer’s infrared vision was key to sizing up the asteroid.

NASA uses ground radar to capture images of Asteroid as it passes near Earth

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8th, 2014, the new views of the object designated “2014 HQ124″ are some of the most detailed radar images of a near-Earth asteroid ever obtained.

The radar observations were led by scientists Marina Brozovic and Lance Benner of NASA’s Jet Propulsion Laboratory, Pasadena, California. The JPL researchers worked closely with Michael Nolan, Patrick Taylor, Ellen Howell and Alessondra Springmann at Arecibo Observatory in Puerto Rico to plan and execute the observations.

NASA selects concepts for Phase I of Innovative Advanced Concepts (NIAC) Program

 

Written by David E. Steitz
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has selected 12 proposals, including three from the Jet Propulsion Laboratory, Pasadena, California, for study under Phase I of the NASA Innovative Advanced Concepts (NIAC) Program, which aims to turn science fiction into fact through pioneering technology development.

The selected proposals cover a wide range of imaginative concepts, including  a submarine to explore the methane lakes of Titan, using neutrinos to perform measurements for the icy moons of the outer planets, and  a concept to safely capture a tumbling asteroid, space debris, and other applications.

NASA’s newly found Asteroid will Safely Pass Earth

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A newfound asteroid will safely pass Earth on June 8th from a distance of about 777,000 miles (1.25 million kilometers), more than three times farther away than our moon.

Designated 2014 HQ124, the asteroid was discovered April 23rd, 2014, by NASA’s NEOWISE mission, a space telescope adapted for scouting the skies for asteroids and comets. The telescope sees infrared light, which allows it to pick up the infrared glow of asteroids and obtain better estimates of their true sizes. The NEOWISE data estimate asteroid 2014 HQ124 to be between 800 and 1,300 feet (250 and 400 meters).

This diagram shows the orbit of asteroid 2014 HQ124, and its location relative to Earth on June 8th. (NASA/JPL-Caltech)

NASA’s Mars Reconnaissance Orbiter discovers large new Crater on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA’s Mars Reconnaissance Orbiter.

The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in the Martian sky caused by intense friction between an incoming asteroid and the planet’s atmosphere.

This is the largest fresh impact crater anywhere ever clearly confirmed from before-and-after images. It is 159 feet across. (NASA/JPL-Caltech/Univ. of Arizona)
