Artificial intelligence helps classify new craters on Mars – IAM Network

#artificialintelligence

An innovative artificial intelligence (AI) tool developed by NASA has helped identify a cluster of craters on Mars that formed within the last decade.The new machine-learning algorithm, an automated fresh impact crater classifier, was created by researchers at NASA's Jet Propulsion Laboratory (JPL) in California -- and represents the first time artificial intelligence has been used to identify previously unknown craters on the Red Planet, according to a statement from NASA. Scientists have fed the algorithm more than 112,000 images taken by the Context Camera on NASA's Mars Reconnaissance Orbiter (MRO). The program is designed to scan the photos for changes to Martian surface features that are indicative of new craters. In the case of the algorithm's first batch of finds, scientists think these craters formed from a meteor impact between March 2010 and May 2012. Related: Latest photos from NASA's Mars Reconnaissance Orbiter"AI can't do the kind of skilled analysis a scientist can," Kiri Wagstaff, JPL computer scientist, said in the statement.

Asteroid samples escaping from jammed NASA spacecraft

FOX News

U.S. Space Force officials swear in first recruits for the defense branch on'Fox & amp; Friends.' CAPE CANAVERAL, Fla. – A NASA spacecraft is stuffed with so much asteroid rubble from this week's grab that it's jammed open and precious particles are drifting away in space, scientists said Friday. Scientists announced the news three days after the spacecraft named Osiris-Rex briefly touched asteroid Bennu, NASA's first attempt at such a mission. The mission's lead scientist, Dante Lauretta of the University of Arizona, said Tuesday's operation 200 million miles away collected far more material than expected for return to Earth -- in the hundreds of grams. The sample container on the end of the robot arm penetrated so deeply into the asteroid and with such force, however, that rocks got sucked in and became wedged around the rim of the lid. In this image taken from video released by NASA, the Osiris-Rex spacecraft touches the surface of asteroid Bennu on Tuesday, Oct. 20, 2020.

The sample container on the end of the robot arm penetrated so deeply into the asteroid and with such force, however, that rocks got sucked in and became wedged around the rim of the lid. Scientists estimate the sampler pressed as much as 19 inches (48 centimeters) into the rough, crumbly, black terrain.

The sample container on the end of the robot arm penetrated so deeply into the asteroid and with such force, however, that rocks got sucked in and became wedged around the rim of the lid. The team was scrambling to put the sample container into the return capsule as early as Tuesday -- much sooner than originally planned -- for the long trip home.

The widespread use and increasing complexity of mission-critical and safety-critical systems at NASA and in the aerospace industry require advanced techniques that address these systems' specification, design, verification, validation, and certification requirements. The NASA Formal Methods Symposium (NFM) is a forum to foster collaboration between theoreticians and practitioners from NASA, academia, and industry. NFM's goals are to identify challenges and to provide solutions for achieving assurance for such critical systems. New developments and emerging applications like autonomous software for Unmanned Aerial Systems (UAS), UAS Traffic Management (UTM), advanced separation assurance algorithms for aircraft, and the need for system-wide fault detection, diagnosis, and prognostics provide new challenges for system specification, development, and verification approaches. Similar challenges need to be addressed during development and deployment of on-board software for both spacecraft and ground systems.


Generative Models (GANs) - Top Videos, Papers & more

#artificialintelligence

The past few years has seen great advancement in the world of generative models (GANs), becoming one of the most promising approaches toward collecting all of the easily accessible open-source information available and using it to develop models and algorithms to analyze and understand. The below blog brings together a general explanation of GANs, alongside the newest papers, video presentations, application methods and more. For a model to be "Generative" must fit in a class of statistical models which contrast against discriminative models. Simply, a generative model is one that can generate new data after learning from the dataset. Therefore, "Generative" describes a class of statistical models that contrasts with discriminative models.


NASA releases never-before-seen pictures of Bennu, an asteroid that may hold the building blocks of life

FOX News

Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. Following Tuesday's historic touchdown on the asteroid Bennu, NASA has released never-before-seen images of the OSIRIS-REx spacecraft kicking up rocks and debris on the space rock's surface. The images are from the point in time when OSIRIS-REx approached and touched down on the surface of Bennu, which is more than 200 million miles from Earth. "The spacecraft's sampling arm – called the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) – is visible in the lower part of the frame," NASA wrote on its website.


Incredible photos reveal the moment NASA's OSIRIS-Rex made historic touchdown on asteroid Bennu

Daily Mail - Science & tech

Stunning images taken from the historic OSIRIS-REx mission show the moment the spacecraft touched down on the asteroid Bennu more than 200 million miles away from Earth to collect a sample of dirt and dust Tuesday night. On Wednesday NASA unveiled videos and images showing the moment the spacecraft pulled off the six-second touch-and-go (TAG) mission where it bounced off the asteroid's surface and picked up samples along the way. The triumphant $1.16 billion mission is the first American effort to take a sample from an asteroid with the hopes to unlock secrets about the origin of life on Earth. The sample will be returned to Earth in 2023. The images show how the spacecraft descended within three feet of the target landing spot dubbed Nightingale on the asteroid while avoiding boulders the size of buildings.


NASA says images suggest 'success' in asteroid sample collection

The Japan Times

WASHINGTON – The U.S. space agency said Wednesday that it likely succeeded in collecting samples through a spacecraft touchdown on asteroid Bennu a day earlier, based on images that captured the activities. "Everything that we can see from these initial images indicates sampling success," Dante Lauretta, a University of Arizona scientist who leads NASA's OSIRIS-REx mission, told an online news conference, although noting that verification activities will continue. As part of the first U.S. mission to carry samples from an asteroid back to Earth, the OSIRIS-REx spacecraft on Tuesday unfurled its robotic arm to touch the surface of Bennu for six seconds, according to NASA. Images unveiled Wednesday showed the disk-shaped sample collector attached at the end of the arm making contact with the surface of the asteroid and crushing some rocks underneath it. The collector, which is 30 centimeters in diameter, then fired nitrogen gas to stir up and lift rocks and dust for capture.
