Italian becomes first European woman on spacewalk outside ISS

Italian Samantha Cristoforetti became the first European woman astronaut to embark on a spacewalk outside the International Space Station on Thursday, NASA footage showed.
Cristoforetti was joined by Russian cosmonaut Oleg Artemyev on the spacewalk which began just before 1500 GMT, with the pair expected to spend around six and half hours more than 400 kilometres (248 miles) above Earth.
Among their tasks is work on a Europe-made robotic arm which just a week ago became embroiled in tensions between Russia and the West over Moscow's war in Ukraine.
Early last week the head of Russian space agency Roscosmos Dmitry Rogozin, furious at the European Space Agency's decision to cut ties with Moscow on a Mars rover mission, told cosmonauts on the ISS to stop using the European Robotic Arm.
But President Vladimir Putin dismissed Rogozin as Roscosmos chief on Friday, and hours later Washington and Moscow said they would renew flights together to the ISS.
Solar storm to hit Earth's magnetic field on July 21

Something is happening to the sun. One of the regions of the solar atmosphere currently exhibiting sunspots caught the attention of observatories on July 11, when there was a sudden increase in ultraviolet and X-ray brightness. The next ones to notice were the amateur radio communities on either side of the Pacific Ocean, when their communications were briefly interrupted.
A solar flare—the emission of electromagnetic radiation and energetic particles located in a small region of the solar atmosphere—had just occurred. It is a region where the magnetic field is particularly strong and complex.
SPECTACULAR FILAMENT ERUPTION: A filament stretching halfway across the solar disk became unstable and erupted away from the Sun. Couple things to note: (1) A section of it twists (magnetic energy being released).
EarthCARE takes a big stretch
Write a comment
ESA’s upcoming EarthCARE satellite mission has just taken a big stretch. Engineers have gently unfolded this new satellite’s huge five-panel solar wing to test that it will deploy correctly once it is in space. The solar wing is a critical part of the satellite, providing the energy for EarthCARE to do its job: to quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere.

AST SpaceMobile, Inc. (NASDAQ: ASTS) reports that its BlueWalker 3 test satellite has been fully assembled and left its Midland, TX headquarters and manufacturing facility.
Over the next few weeks, BlueWalker 3 will be undergoing final environmental testing at an off-site facility in California, which will provide flight data to be used during the launch at Cape Canaveral.

Gemini South, one of the world's most productive and powerful optical-infrared telescopes, received a major capability boost with the successful installation of a new high-resolution spectrograph called GHOST constructed by an international consortium.

It's been nearly a century since astronomer Fritz Zwicky first calculated the mass of the Coma Cluster, a dense collection of almost 1,000 galaxies located in the nearby universe. But estimating the mass of something so huge and dense, not to mention 320 million light-years away, has its share of problems - then and now. Zwicky's initial measurements, and the many made since, are plagued by sour Webb telescope may have already found most distant known galaxy

Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday.
Known as GLASS-z13, the galaxy dates back to 300 million years after the Big Bang, about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for As A New Method to Detect Exoplanets

In recent years, a large number of exoplanets have been found around single 'normal' stars. New research shows that there may be exceptions to this trend. Researchers from the Autonomous University of Nuevo Leon (UANL), the National Autonomous University of Mexico (UNAM), and New York University Abu Dhabi suggest a new way of detecting dim bodies, including planets, orbiting exotic binary stars When Mars throws you a curveball Sol 3539-3540

The rover has been making its way along the "Bolivar" ridge, dodging small boulders and rocks that have apparently eroded off the hillside as seen in the above engineering camera image. Unfortunately, due to the complex terrain our last drive ended about 11 meters short of its anticipated location.
Because of the unexpected rover heading, the antenna we usually use to uplink plans directly
