NASA Swift Satellite and AI Improve Measurement of Gamma-Ray Bursts
Write a comment
Astronomers are utilizing AI to measure the expansion of the universe. Two studies led by Maria Dainotti, a visiting professor with UNLV's Nevada Center for Astrophysics and assistant professor at the National Astronomical Observatory of Japan (NAOJ), applied machine learning models to enhance distance measurements for gamma-ray bursts (GRBs). GRBs are the most luminous explosions in the univers NASA satellite detects smaller object in black hole pair for the first time

Several international research groups have confirmed that two black holes exist at the center of the distant galaxy OJ 287, a theory first suggested by astronomers at the University of Turku, Finland. A new study shows that satellite observations conducted in 2021 revealed the smaller black hole of the pair for the first time.
In 2021, NASA's exoplanet-hunting satellite was pointed towards Intuitive Machines Achieves Lunar Landing with Sciaky EBAM Component

Sciaky has extended its pioneering work in additive manufacturing to lunar exploration by producing a critical part for Intuitive Machines' IM-1 mission to the Moon. Using a refractory alloy and one of its Electron Beam Additive Manufacturing (EBAM) systems, Sciaky completed the upper section of the main engine nozzle in just sixteen hours.

Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear.
"Since its discovery in 2016, there have been many attempts to reproduce Crater 2's unusual properties, but it has proved very challenging," said ISS 90th spacewalk will retreive microorganisms from exterior of space station

NASA astronauts will venture into space Thursday to scrape microorganisms from the outside of the International Space Station and study the origins of life.
Their live-streamed spacewalk also will include some repairs.

A new collaboration between ESA and Schiphol Airport in the Netherlands has got passengers thinking about space. Digital screens throughout the airport featuring stunning satellite images of Earth have been stopping travellers in their tracks. That's because these pictures from space are part of a fun Where on Earth? travel quiz.
Eclipse-making double-satellite Proba-3

Proba-3 is ESA’s – and the world’s – first precision formation flying mission. A pair of satellites will fly together relative to the Sun so that one casts a precisely-controlled shadow onto the other, to create a prolonged solar eclipse in orbit. In the process the mission will open up the Sun’s faint surrounding coronal atmosphere for sustained study. Normally this corona is rendered invisible by the brilliant face of the Sun, like a firefly next to a bonfire.
Due for launch together this autumn, the two Proba-3 satellites will fly 144-m apart for up to six hours

Production of Galileo Second Generation satellites advances at full speed after two independent Satellite Critical Design Review boards have confirmed that the satellite designs of the respective industries meet all mission and performance requirements. This achievement is another crucial milestone hit on time in the ambitious schedule to develop the first 12 satellites of the Galileo Second Generation fleet.
Short commercial space flights may not have big impact on health
Write a comment
The first all-civilian space mission is shedding light on the potential health risks facing private astronauts. The takeaway is short-duration spaceflights appear to pose none that are significant. The study sample was small—four people who spent three days in low-earth orbit (LEO) on the 2021 Inspiration4 mission.
But it lays the groundwork for an open biomedical database for commercial astronauts' health data and establishes best practices for collecting and dealing with this information, according to a team led by Baylor College of Medicine's Center for Space Medicine in Houston.
"Civilian participants have different educational backgrounds and medical conditions compared to astronauts with career-long exposure to space flight," said study co-author Dr. Emmanuel Urquieta, chief medical officer of the Translational Research Institute for Space Health (TRISH) at Baylor.
"Understanding their physiological and psychological responses to spaceflight and their ability to conduct research is of utmost importance as we continue to send more private astronauts into space."
Like astronauts who do months-long tours of duty on the International Space Station, the hazards facing these four included radiation exposure, sustained microgravity, confinement and isolation.
