Scientists discover how first quasars in universe formed
Thursday, 07 July 2022 09:16
The mystery of how the first quasars in the universe formed - something that has baffled scientists for nearly 20 years - has now been solved by a team of astrophysicists whose findings are published in Nature.
The existence of over 200 quasars powered by supermassive black holes less than a billion years after the Big Bang had remained one of the outstanding problems in astrophysics becau NASA Rockets Launch from Australia to Seek Habitable Star Conditions
Thursday, 07 July 2022 09:16
A NASA Black Brant IX suborbital sounding rocket was successfully launched at 9:47 a.m. EDT (11:17 p.m. ACST) July 6, 2022, from the Arnhem Space Centre (ASC) in the Northern Territory of Australia. The launch was for the Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars, or SISTINE, mission for the University of Colorado, Boulder. Preliminary anal Could we eavesdrop on communications that pass through our solar system
Thursday, 07 July 2022 09:16
Communications across the vastness of interstellar space could be enhanced by taking advantage of a star's ability to focus and magnify communication signals. A team of graduate students at Penn State is looking for just these sorts of communication signals that might be taking advantage of our own sun if transmissions were passing through our solar system.
A paper describing the technique Embry-Riddle Joins NSF Space Weather Challenge

Just as the ocean's surface can be calm and glassy or churning big waves, a moody portion of space called the ionosphere can smoothly reflect communication signals or bounce them into oblivion. Predicting the ionosphere's wild mood swings is the focus of new National Science Foundation (NSF) support for research at five top engineering schools, including Embry-Riddle Aeronautical University.

The first satellite to be built under ESA’s Eurostar Neo programme has completed mechanical tests designed to demonstrate its ability to withstand the vibration that occurs during launch.
Virgin Galactic taps Boeing subsidiary to build motherships
Thursday, 07 July 2022 07:24
Virgin Galactic announced Wednesday that it is partnering with a Boeing subsidiary to manufacture the next generation of the twin-fuselage aircraft used to carry aloft the space tourism company's rocket ship.
Aurora Flight Sciences will build two of the special carrier planes at its facilities in Mississippi and West Virginia. Final assembly still will take place at Virgin Galactic's facility in Mojave, California, with the first mothership produced under the contract expected to enter service in 2025.
Each of the aircraft will be designed to fly up to 200 launches per year.
Virgin Galactic officials said that outsourcing the work will provide access to labor, minimize supply chain disruptions and lead to faster production times. The company has repeatedly pushed back the timeline for launching paying customers, with commercial service now expected in 2023.
Virgin Galactic CEO Michael Colglazier said the next-generation motherships will be integral to scaling up the company's operations.
"They will be faster to produce, easier to maintain and will allow us to fly substantially more missions each year," he said in a statement. "Supported by the scale and strength of Boeing, Aurora is the ideal manufacturing partner for us.
NASA re-establishes contact with CAPSTONE spacecraft

NASA has regained communications with its new lunar spacecraft, the space agency confirmed on Wednesday.
"Mission operators have re-established contact with NASA's Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) spacecraft," NASA said in a statement.
It did not immediately provide additional details or updates.
"We have re- Boeing subsidiary to build two new Virgin Galactic motherships
Thursday, 07 July 2022 03:54
Virgin Galactic confirmed Wednesday it is retaining Boeing subsidiary Aurora Flight Sciences to build two next generation motherships, the company announced on Wednesday.
The agreement calls for the first ship to enter service in 2025, the same year Virgin Galactic's first Delta-class spaceship is expected to begin revenue payload flights.

Testing the effect of multicolor lighting on improving people's psychological state
Wednesday, 06 July 2022 15:02
As missions for deep space exploration and space habitats are put on the agenda, astronauts need to withstand being tested by multiple stressors in confined and isolated conditions during such long flights, especially because in deep space exploration, problems such as signal delays make astronauts feel the anxiety of being far away from Earth and the psychological fear of deep space.
According to a series of experiments conducted recently on Earth and during current space missions aboard the International Space Station (ISS), NASA believes that monotony of vision, in particular, aggravates the crew's anxiety, irritability, and depression. Moreover, a large number of studies have also found that crew members on long-term missions on the Antarctic Space Simulation Station are extremely susceptible to psychological problems caused by visual monotony and monochromatic colors.
