Artificial Intelligence In Space Exploration
In this video we will learn about the use of artificial intelligence in space exploration. Space is fascinating. There is hardly anyone who hasn’t looked at the night sky and imagined traveling through the space. There are hardly few rivalries that benefited mankind. One of them is the cold war between Russia and USA. That opened up the opportunity in space exploration. When one of these countries tried to shine over the other one, mankind shined with knowledge about space. And from there to today’s SPACEX age we have come across a long way. Starting from manually calculating the trajectory for moon landing to modern day usage of artificial intelligence in space exploration we have come a long way and yet there are many things to be done. By the way, did you know, Katherine Johnston, an African-American female physicist was the first person to do the calculations for the first actual moon landing in 1969.

Machine Learning and Cosmology: New Approaches to Constraining the Dark Universe
Matias Carrasco Kind is a current astronomy graduate student and a CSE fellow at the University of Illinois at Urbana-Champaign. His current research interests lie in cosmology and extragalactic astronomy, especially in large scale structure, galaxy formation and evolution, computational and theoretical cosmology, environmental dependence of galaxy properties, photometric redshift estimation, machine learning techniques and data mining.

Dr Francois Lanusse - Exploring the Cosmos with Deep Learning
The main challenge of modern Cosmology is to answer pressing questions on the physical nature of dark matter and dark energy, which despite accounting for ~95% of the Universe today remain complete mysteries. This is what motivates a new generation of cosmological surveys which will map the Universe in great detail and on an unprecedented scale, implying a great potential for new discoveries but also new and outstanding challenges at every step of the science analysis, from image processing to the modelling of galaxy physics. In this talk, I will illustrate how recent advances in Deep Learning can be used to address some of these challenges and to exploit this wealth of data in new and exciting ways. A first application is the automated detection of rare astronomical objects, in this case strong gravitational lenses, using deep residual networks. In this typical image classification problem, Deep Learning has the potential of eliminating the need for human visual inspection which would have been intractable at the scale of future surveys. In a second example of application, I will present recent deep generative models and how they can be applied to emulate realistic signals when a proper physical model is lacking. In our specific application, we use deep generative models to produce realistic galaxy images, an essential part of the simulation pipeline necessary to the validation and calibration of our measurements. The last example I will mention is Deep Learning on graphs, more specifically how we use graph convolutional networks to model the properties of galaxies along the cosmic web (the large-scale structure of the Universe) in large-scale cosmological simulations.

Prof. Ofer Lahav: From Deep Learning to the Dark Universe
The talk will illustrate how new Artificial Intelligence and Machine Learning methods can help unveiling the mysteries of Dark Matter and Dark Energy from large deep galaxy surveys. Prof Ofer Lahav is an astrophysicist of international renown and holds the Perren Chair of Astronomy at University College London. He is famous for his advanced research on Dark Matter and Dark Energy by using methods like Machine Learning and is one of the founders of the Dark Energy Survey (DES). He has served as Vice-President of the Royal Astronomical Society and Co-Chair of the international DES Science Committee and has been awarded a wide variety of prices and honours. His projects include HST CLASH, DESI, LSST, Euclid, and several others focussed on understanding and analysing the behaviour of Dark Matter.

Understanding Galaxy Evolution through Machine Learning
Presentation for Summer All Zoom Epoch of Reionization Astronomy Conference (SAZERAC) 2020

John Wu - Deep learning in astrophysics: galaxy scaling relations
Deep learning in astrophysics: galaxy scaling relations. I will discuss some applications deep convolutional neural networks (convnets), and present a high-level overview of how to select, optimize, and interpret convnet models. We have trained a convnet to recognize a galaxy's chemical abundance using only an image of the galaxy; the traditional approach using spectroscopy requires at least an order of magnitude more telescope time and achieves a comparable level of accuracy to our method. We discover that the convnet can recover an empirically known scaling relation that connects galaxies' chemical enrichment and star formation histories with zero additional scatter, implying that there exists (and that the convnet has learned) a novel representation of the chemical abundance that is strongly linked to its optical-wavelength morphology.

Yashar Hezaveh: Mapping distant galaxies with artificial intelligence
We are in the midst of a revolution in computing, with "machine learning" algorithms solving problems for which major progress was thought to be decades away. As a result, computers can now exceed human performance at tasks such as recognizing patterns in images, playing complex games such as Go, and even driving cars. Can we harness the same machine learning algorithms to advance our understanding of physics? Understanding materials at the atomic level could lead to rapid advances in areas such as solar energy harvesting and the design of new computer hardware. The complex behavior of trillions of atoms all obeying the esoteric rules of quantum mechanics is not, however, easy for humans to untangle on their own. At this teachers' conference, we hear from scientists using the techniques of artificial intelligence and machine learning to advance our understanding of the quantum behavior of such matter as magnets, metals and superconductors, as well as the constituents of atoms. We also hear how insights from physics could be repurposed to advance the field of machine learning itself.

Sensing to Intelligence: From Human Body to Black Holes in Space / Caltech Seminar Day Session II
Caltech professors Azita Emami and Katherine Bouman discussed a holistic approach that brings together the two distinct fields of sensor technology and artificial intelligence through the co-design of sensors and algorithms. The aim is to create sensor networks that intelligently and autonomously process their own data and adapt their activity in real time based on what they detect, enabling transformative discoveries in areas ranging from neural signals in the human body to black holes in space.

Speakers: Katherine Bouman Assistant Professor of Computing and Mathematical Sciences and Electrical Engineering; Rosenberg Scholar

What Would a Journey to the Black Hole Be Like?
Today, I'm setting off on a journey toward the nearest black hole. But don't worry - I'll keep you in the know by live-streaming my entire adventure! I'll have someone to talk to during the flight, and he can help me if things get really tough! My travel buddy's name is Liam. Liam is a robot with artificial intelligence. Space distances are seriously long. That's why traveling there would take way more time than you'd like to spend on the road! For example, Voyager 1, a space probe launched in 1977, was traveling out of the Solar System at a speed of 40,000 miles per hour. If my spacecraft moved at the same speed, it would take me a whole 77,000 years to get to the nearest star! But luckily, my spaceship is much faster than that. So let the journey begin!

The Path to Safe Fusion Energy through Deep Learning
When the plasma inside a fusion reactor becomes unstable, there can be a release of energy that seriously damages the reactor. Key to preventing damage is predicting when these disruptions are about to happen.

Looking for exoplanets using supervised machine learning
"Data science in astronomical high-contrast imaging: looking for exoplanets using supervised machine learning" by Carlos Alberto Gomez Gonzalez , IPAG, Université Grenoble Alpes

Artificial Intelligence and NASA Data Used to Discover Eighth Planet Circling Distant Star
Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA’s Kepler space telescope. The newly-discovered Kepler-90i -- a sizzling hot, rocky planet that orbits its star once every 14.4 days -- was found by researchers from Google and The University of Texas at Austin using machine learning. Machine learning is an approach to artificial intelligence in which computers “learn.” In this case, computers learned to identify planets by finding in Kepler data instances where the telescope recorded signals from planets beyond our solar system, known as exoplanets.

AI helped NASA find a new planet!
Follow Nexter for more: In the most recent NASA news, they have discovered an eighth planet which revolves around the star. This new planet adds to the growing Earth like planets list. Known as one of the Kepler planet, this planet was discovered by Google’s artificial intelligence by thoroughly searching those weak signals which has been overlooked by the Kepler Space Telescope. This newest galactic figure adds up the new planets discovered by NASA. This new planet, which is being touted as “Earth 2.0”, this Kepler new planet is located around Kepler-90 which is a star which has a distance of 2,500 light years from earth. This star was discovered in 2014. The new planet, however, cannot handle life like the Earth does because of its solar system. Kepler 90 is bigger by 20 percent and 5 percent hotter compared to our sun. The participation of computers and artificial intelligence in the planet searching process should not be of concern, however, by human beings. Artificial intelligence and technology are just there to help scientists and researchers look for more planets and find one that can support human life. More and more Earth sized planets are being discovered and being added into the NASA new planets. A lot of them are Kepler exoplanets. Astronomy and heavenly bodies are something that is very interesting, and every intergalactic news is being followed instantly.

SETI Talks - Big Astronomy Begins: Searching for Exoplanets with AI
To uncover the mysteries of the universe, astronomers are becoming greedy, making more observations than they can possibly analyze manually. Large photometric surveys from space telescopes like Kepler and the future TESS are no exception and today modern astronomers use artificial Intelligence (AI) algorithms to help them reveal the existence of exoplanets hidden in many years of observations of hundreds of thousands of stars. For this SETI Talk, we invited two researchers involved in the Kepler mission and AI to discuss the potential of neural networks to transform astronomy. Jeff Smith, Data scientist at the SETI Institute, has developed data processing and planet detection algorithms for Kepler since 2010 and is now involved in developing the pipeline for the future TESS mission. Chris Shallue, a senior software engineer at Google AI has used a neural network to analyze archival data from the Kepler Space Telescope to reveal the existence of two unknown exoplanets, named Kepler-90i and Kepler-80g. After presenting their recent work, we will discuss the impact of this new mode of scientific discovery, where artificial intelligence can assist humans in mapping out parts of the galaxy that have not yet been fully revealed.

Chris Shallue is a Senior Research Software Engineer on the Google AI team in Mountain View, California. His research is currently focused on machine learning techniques for identifying planets in data collected by the NASA Kepler space telescope. He also works on image captioning, natural language modeling and machine learning theory. Chris was previously a member of the Google Display Ads team where he worked on ad selection and personalization for GMail and Google Maps. Prior to joining Google, Chris was teaching, studying and researching mathematics.

Dr. Jeffrey Smith began his academic passion in the field of High Energy Accelerator Physics. His Ph.D. thesis was on the design of the International Linear Collider (ILC), a 22 mile-long electron-positron accelerator that will complement the discoveries being made at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. After Cornell, Jeff joined the SLAC National Accelerator Laboratory at Stanford University to continue his work on the ILC and also to develop upgrade hardware for the LHC. After a successful career looking into the tiniest of inner-spaces Jeff decided to look up to the stars. Dr. Smith, now at the SETI Institute, develops data processing and planet detection algorithms for the Kepler and TESS Missions. Eking out planet signals in the Kepler data has proven to be a challenging and rewarding endeavor but looking toward the future, Dr. Smith is involved with developing new methods for use with the Transiting Exoplanet Survey Satellite (TESS), a new NASA planet finding mission to find Earth’s nearest cousins in a our galactic back yard.

Microsoft's AI For Earth
Human society is faced with an unprecedented challenge to mitigate and adapt to changing climates, ensure resilient water supplies, sustainably feed a population of 10 billion, and stem a catastrophic loss of biodiversity. Time is too short, and resources too thin, to achieve these outcomes without the exponential power and assistance of AI. Early efforts are encouraging, but current solutions are typically one-off attempts that require significant engineering beyond what’s available from the AI research community. In this session we will explore, in collaboration with the Computational Sustainability Network (a twice-funded National Science Foundation (NSF) Expedition) the latest applications of AI research to sustainability challenges, as well as ways to streamline environmental applications of AI so they can work with traditional academic programs. The speakers in this session will set the scene on the state of the art in AI for Earth research and frame the agenda for the next generation of AI applications.

Geospatial Machine Learning for Urban Development
Ilke Demir, Postdoctoral Research Scientist, Facebook Presented at MLconf 2018 Abstract: The collective mission of mapping the world is never complete: We need to discover and classify roads, settlements, land types, landmarks, and addresses. The recent proliferation of remote sensing data (overhang images, LiDAR, sensors) enabled automatic extraction of such structures to better understand our world. In this talk, we will first mention the motivation and results of DeepGlobe Satellite Image Challenge[1][2], for road extraction, building detection, and land cover classification. Then we will go into details of an example approach[3] which proposes a complete system to use deep learning for generating street addresses for unmapped developing countries. The approach applies deep learning to extract road vectors from satellite images, then processes the street network to output linear and hierarchical street addresses, by labeling regions, roads, and blocks; based on addressing schemes around the world and coherent with human cognitive system. We will share and demonstrate the motivation and algorithm behind the scenes, then compare them to current open and industrial solutions, and walk through our open source code[4] to generate the addresses for a given bounding box.

Talk by Dr. Jeremy Frank of NASA AMES at Arizona State University. (A joint FSE-SESE Colloquium co-hosted by CIDSE, SESE and SEMTE) 2/18/2020 Over the past decade, the NASA Autonomous Systems and Operations (ASO) project has developed and demonstrated numerous autonomy enabling technologies employing AI techniques. Our work has employed AI in three distinct ways to enable autonomous mission operations capabilities. Crew Autonomy gives astronauts tools to assist in the performance of each of these mission operations functions. Vehicle System Management uses AI techniques to turn the astronaut's spacecraft into a robot, allowing it to operate when astronauts are not present, or to reduce astronaut workload. AI technology also enables Autonomous Robots as crew assistants or proxies when the crew are not present. We first describe human spaceflight mission operations capabilities. We then describe the ASO project, and the development and demonstration performed by ASO since 2011. We will describe the AI techniques behind each of these demonstrations, which include a variety of symbolic automated reasoning and machine learning based approaches. Finally, we conclude with an assessment of future development needs for AI to enable NASA's future Exploration missions.

Landuse Classification from Satellite Imagery using Deep Learning
With the abundance of remote sensing satellite imagery, the possibilities are endless as to the kind of insights that can be derived from them. One such use is to determine land use for agriculture and non-agricultural purposes. In this talk, we’ll be looking at leveraging Sentinel-2 satellite imagery data along with OpenStreetMap labels to be able to classify land use as agricultural or non-agricultural. Sentinel-2 data has a 10-meter resolution in RGB bands and is well-suited for land use classification. Using these two datasets, many different machine learning tasks can be performed like image segmentation into two classes (farm land and non-farm land) or more challenging task of identification of crop type being cultivated on fields. For this talk, we’ll be looking at leveraging convolutional neural networks (CNNs) built with Apache MXNet to train deep learning models for land use classification. We’ll be covering the different deep learning architectures considered for this particular use case along with the appropriate metrics. We’ll be leveraging streaming pipelines built on Apache Flink and Apache NiFi for model training and inference. Developers will come away with a better understanding of how to analyze satellite imagery and the different deep learning architectures along with their pros/cons when analyzing satellite imagery for land use.

Collision Avoidance in Space

Youtube search... ...Google search ...News search

Challenge: Today, active collision avoidance among orbiting satellites has become a routine task in space operations, relying on validated, accurate and timely space surveillance data. For a typical satellite in Low Earth Orbit, hundreds of alerts are issued every week corresponding to possible close encounters between a satellite and another space object (in the form of conjunction data messages CDMs). After automatic processing and filtering, there remain about 2 actionable alerts per spacecraft and week, requiring detailed follow-up by an analyst. On average, at the European Space Agency, more than one collision avoidance manoeuvre is performed per satellite and year. In this challenge, you are tasked to build a model to predict the final collision risk estimate between a given satellite and a space object (e.g. another satellite, space debris, etc). To do so, you will have access to a database of real-world conjunction data messages (CDMs) carefully prepared at ESA. Learn more about the challenge and the data.

Results: Spacecraft collision avoidance procedures have become an essential part of satellite operations. Complex and constantly updated estimates of the collision risk between orbiting objects inform the various operators who can then plan risk mitigation measures. Such measures could be aided by the development of suitable machine learning models predicting, for example, the evolution of the collision risk in time. ...This paper describes the design and results of the competition and discusses the challenges and lessons learned when applying machine learning methods to this problem domain.

Powerful A.I. Engine simulates the Universe Formation
For the first time, scientists have used artificial intelligence to create complex, three-dimensional simulations of the Universe. It's called the Deep Density Displacement Model, or (D^3)M, and it's so fast and so accurate that the astrophysicists who designed it don't even know how it does what it does. What it does is accurately simulate the way gravity shapes the Universe over billions of years. Each simulation takes just 30 milliseconds - compared to the minutes it takes other simulations.

Computing a Universe Simulation
Physics seems to be telling us that it’s possible to simulate the entire universe on a computer smaller than the universe.

Shirley Ho - The First AI Simulation of the Universe is Fast and Accurate (February 26, 2020)
A full understanding of the evolution of the universe’s structure is one of the holy grails of modern astrophysics. Astrophysicists survey large volumes of the universe and compare the findings to computer simulations. Simulating the movement of billions of particles over billions of years is a daunting task, however, even when using the simplest physical models. In this lecture, Shirley Ho will discuss her team’s work building a deep neural network that learns from a set of pre-run numerical simulations and predicts the large scale structure of the universe. Extensive analysis demonstrates that their deep-learning technique outperforms the commonly used fast approximate simulation method in predicting cosmic structure in the non-linear regime. They also show that their method can accurately extrapolate far beyond its training data and predict structure formation for significantly different cosmological parameters. This ability to extrapolate outside its training set is highly unexpected and remains a mystery.

AI Learning to land on The Moon. Lunar Lander V2 reinforcement learning
This deep learning reinforcement algorithm is using an off policy Sarsa (State-Action-Reward-State-Action) Agent to learn to control this moon landing capsule.The AI can use the left thrust, right thrust, main thrust or do nothing. This is running agent is running in OpenAI Lab. OpenAI Lab is an experimentation framework for Reinforcement Learning using OpenAI Gym, TensorFlow, and Keras. With Lunar Lander V2 the agent gets a reward for moving from the highest point of the screen to landing zone and landing with zero speed. On the off chance that lander moves far from landing cushion it loses reward points. Episode completes if the lander crashes or lands, getting extra points. Using main thruster cost points. Fuel is endless, so the agent can figure out how to fly and then land. The data on the right shows reward overtime with our 150 episode exploration rate, mean reward overtime and the network loss overtime.

Landing a SpaceX Falcon Heavy Rocket
Can we land a SpaceX Falcon Heavy Rocket in simulation using machine learning? Yes! Reinforcement learning is a technique that lets an agent learn how best to act in an environment using rewards as its signal. OpenAI released a library called Gym that lets us train AI agents really easily. We'll use a combination of the TensorFlow and gym libraries to build an RL agent capable of landing a rocket perfectly. The specific technique we're using is called proximal policy optimization, this is an actor-critic algorithm that is really popular. Lets get started!
