Calibrating NASA's images of the Sun using AI

#artificialintelligence

Since it launched on February 11, 2010, NASA's Solar Dynamics Observatory, or SDO, has provided high-definition images of the Sun for over a decade. The images have provided a detailed look at various solar phenomena. SDO uses Atmospheric Imaging Assembly (AIA) to continuously look at the sun, taking images in 10 wavelengths every 10 seconds. It creates a wealth of information about our Sun never previously possible. Due to constant staring, AIA degrades over time, and the data needs to be frequently calibrated.


NASA is using AI to take better pictures of the sun as

The sun may be the most powerful source of energy in the Milky Way, but NASA researchers are using artificial intelligence to get a better view of the giant ball of gas. The US space agency is using machine learning on solar telescopes, including its Solar Dynamics Observatory (SDO), launched in 2010, and its Atmospheric Imagery Assembly (AIA), imaging instrument that looks constantly at the sun. This allows the agency to snap incredible pictures of the celestial giant, while limiting the effects of solar particles and'intense sunlight,' which begins to degrade lenses and sensors over time. The sun goes through an 11-year cycle where it goes from very active to less active. It is tracked by sunspots and it is currently going through a quiet phase.


Artificial intelligence helps improve NASA's eyes on the Sun

#artificialintelligence

A group of researchers is using artificial intelligence techniques to calibrate some of NASA's images of the Sun, helping improve the data that scientists use for solar research. The new technique was published in the journal Astronomy & Astrophysics on April 13, 2021. A solar telescope has a tough job. Staring at the Sun takes a harsh toll, with a constant bombardment by a never-ending stream of solar particles and intense sunlight. Over time, the sensitive lenses and sensors of solar telescopes begin to degrade.


Scientists finally understand Mars's crust after Nasa mission examines 'Marsquakes'

The Independent - Tech

Scientists have finally been able to understand the crust underneath the surface of Mars. The research represents the first time that humanity has been able to start mapping the interior of another planet beyond our own Earth. The new research relied on data taken from Nasa's InSight mission, which has been looking for Marsquakes that reverberate across its surface. Using information about those quakes, researchers are able to understand what might be lurking beneath the Martian surface. Beneath the InSight landing site, the crust is either approximately 20 kilometres or 39 kilometres thick, according to an international research team led by geophysicist Dr Brigitte Knapmeyer-Endrun at the University of Cologne's Institute of Geology and Mineralogy and Dr Mark Panning at Jet Propulsion Laboratory, California Institute of Technology (Caltech).

The energy consumption from crypto mining has been increasingly exponentially with the increasing adoption of crypto. This increasing becoming of concern as it should be. Large parts of the world suffer from energy deprivation due to unaffordability and inadequate energy generation. At the same time climate change goals will require the world to reduce net emission much of which is produced from electricity generation. Supporting the world's growth and generating the and while reducing emissions when large populations suffer from energy deficiency is a very difficult issue requires trillions is capital over the coming 2 decades.


NASA's Perseverance rover is hunting for signs of life on Mars - and NASA will share initial results

Daily Mail - Science & tech

NASA's Perseverance rover has officially started its search for ancient life on Mars and the US space agency will share the initial findings on Wednesday. According to a NASA statement, the $2.7 billion rover is using its seven-foot mechanical arm to analyze Martian rocks with X-rays and ultraviolet light. This allows the rover to'zoom in for closeups' of tiny segments of rock that may show signs of microbial activity in the past. Known as PIXL (Planetary Instrument for X-ray Lithochemistry), the X-ray instrument on the arm'delivered unexpectedly strong science results' while it was still being tested, a period that lasted 90 sols (Martian days), according to Abigail Allwood, PIXL's principal investigator at NASA JPL. NASA's Perseverance rover has started its search for ancient life on Mars. A news conference will be held on Wednesday at 1 p.m. EST to discuss the results PIXL, one of seven instruments aboard NASA's Perseverance Mars rover, is equipped with light diodes circling its opening to take pictures of rock targets in the dark'We got our best-ever composition analysis of Martian dust before it even looked at rock,' Allwood said.


NASA's Perseverance Mars rover begins hunt for signs of past life

FOX News

NASA's Perseverance Mars rover has begun its hunt for evidence of ancient microbial life. The spacecraft, which landed on the red planet in February, has tested an array of instruments on its 7-foot robotic arm. In a Monday release, NASA said that Perseverance had commenced its probe of Martian rocks and sediment, testing detectors and capturing its first science readings. The rover will use X-rays and ultraviolet light to examine rocks in addition to zooming for "closeups" of surfaces. PIXL, one of seven instruments aboard NASA's Perseverance Mars rover, is equipped with light diodes circling its opening to take pictures of rock targets in the dark.


Russia launches new 'walking' robot arm module to the International Space Station

The Independent - Tech

A Proton rocket launched from the Baikonur Cosmodrome in Kazakhstan today, taking the European Robotic Arm (ERA) payload to the International Space Station. The 11-meter long robot has been folded and attached to the Multipurpose Laboratory Module, also called'Nauka', that will be its home base when it reaches the ISS. The rocket put Nauka and the ERA into orbit at 16:08pm GMT, ten minutes after liftoff, at an altitude of nearly 200 kilometres above the Earth. The ISS already has two robotic arms, which are used to berth spacecraft and transfer payloads and astronauts, but neither arm can each the Russian segment, the European Space Agency said. Instead, the ERA will'walk' around the Russian parts of the orbital complex, handling components up to 8000 kilograms, and transport astronauts when it eventually reaches the station.


Russia is launching a new module for the International Space Station

New Scientist

Russia is launching a new module for the International Space Station (ISS), after more than a decade of delays. The Nauka module is set to lift off from Baikonur Cosmodrome in Kazakhstan on top of a Proton-M rocket at around 1500 GMT today, along with a new robotic arm for the station created by the European Space Agency. The ISS is composed of modules and equipment from different space agencies including Europe, Japan and Canada, but the bulk of the station is composed of two main sections, a Russian segment and a US segment. At 13 metres long and weighing more than 20 tonnes, Nauka, also called the Multipurpose Laboratory Module, will be among the largest in Russia's half. After launch, Nauka will take eight days to reach the ISS.


NASA has just fixed the mysterious computer problem with its famous space telescope

ZDNet

NASA's Hubble telescope has been taking snaps of the universe almost 600 kilometers above the surface of the Earth for 31 years. NASA's Hubble telescope, the giant space observatory taking snaps of the universe almost 600 kilometers above the surface of the Earth, is all set to get back to work after a month-long break caused by a stubborn computer glitch. The space agency has confirmed that Hubble is up and running again, with all science instruments onboard the spacecraft operational and ready to start collecting data for researchers on the ground. After some final instrument calibrations are completed, the telescope will carry out an observation at the end of the week – the first one since some of Hubble's key hardware started playing up last month.
