Large satellite constellations can unintentionally generate electromagnetic noise, creating an additional source of interference for radio astronomers.
Time to act on light pollution, say leading experts at NAM conference
Wednesday, 05 July 2023 09:27
Action on light pollution is long overdue, campaigners will say at a panel event (3 July) at the National Astronomy Meeting in Cardiff. The panellists call for UK governments and local authorities to put policies in place to restore our view of the skies and to mitigate the impacts of excessive light at night on biodiversity and potentially human health.
Light pollution is rarely far from iRocket contracts with US Space Force to transform how launch vehicles are powered
Wednesday, 05 July 2023 09:27
Innovative Rocket Technologies Inc. (iRocket), a company that provides low cost and rapid access to space with its 100% reusable rockets, announced that it signed a contract with the U.S. Space Force Space Systems Command (SSC). Under the contract, iRocket will further develop its highly reusable rocket engine, which will transform how launch vehicles are powered with clean, sustainable propella Time appears five times slower in early universe: study
Wednesday, 05 July 2023 09:27
Time appears to run five times slower in the early universe, scientists said on Monday, for the first time using extraordinarily bright cosmic objects called quasars as "clocks" to confirm this strange phenomenon.
Einstein's theory of relativity predicts that because space is expanding, "we should see the distant universe run in slow motion," said Geraint Lewis, an astrophysicist at the Univ Hawaii observatories play criical role adding color to new space mission
Wednesday, 05 July 2023 09:27
Observing billions of galaxies across more than a third of the sky and building a 3D map of the universe are all part of the Euclid mission that the European Space Agency launched with its Euclid satellite from Cape Canaveral, Florida. Euclid's dataset is getting a big helping hand from observations taken at three observatories in Hawaii.

As two companies prepare to begin or resume commercial suborbital human spaceflights, they are facing uncertainty about how the safety of the people on those flights will be regulated.
Unfavourable weather delays final Ariane 5 launch
Tuesday, 04 July 2023 09:00
The farewell flight of Europe's workhorse Ariane 5 rocket, scheduled for Tuesday, has been postponed for 24 hours due to bad weather, operator Arianespace said.
The 117th and final flight of an Ariane 5 rocket, after 27 years of launches, had been due to take off between 2130 and 2305 GMT from Europe's spaceport in Kourou, French Guiana.
"Due to unfavourable winds at high altitude above ISRO terminates hot test for semi-cryogenic engine midway
Tuesday, 04 July 2023 09:00
The Indian Space Research Organisation (ISRO) recently experienced a hiccup in their semi-cryogenic engine development project. A scheduled hot test was halted midway due to unexpected engine performance.
On July 1, 2023, ISRO revealed that it had initiated the inaugural hot test on an intermediate configuration of the semi-cryogenic engine, designated as Power Head Test Article (PHTA). Th Quasar 'clocks' show Universe was five times slower soon after the Big Bang
Tuesday, 04 July 2023 09:00
Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein's expanding universe.
Einstein's general theory of relativity means that we should observe the distant - and hence ancient - universe running much slower than the present day. However, peering back that far in time has proven elusive. Scientists have now SmartSat CRC Pledges $7M for Autonomous AI Spacecraft Development

Findings from a recent study underscore the potential for satellite-based early warning systems to bolster evacuation protocols in certain Asian communities. Published on April 27, 2023, in the Emergency Management Science and Technology journal, the study highlights the limitations of conventional ground-based telecommunication systems in regions such as Bangladesh, Bhutan, and Mongolia. Chinese private space company to launch latest rocket in 2024
Tuesday, 04 July 2023 09:00
In the vanguard of the rapidly evolving commercial space industry, Beijing-based private firm Space Pioneer plans the inaugural launch of its TL 3 carrier rocket in 2024. The launch will signify an ambitious stride toward fortifying China's presence in the commercial space launch market.

Tuesday, 04 July 2023 06:57
The farewell flight of Europe's workhorse Ariane 5 rocket, scheduled for Tuesday, has been postponed for 24 hours due to bad weather, operator Arianespace said.
The 117th and final flight of an Ariane 5 rocket, after 27 years of launches, had been due to take off between 2130 and 2305 GMT from Europe's spaceport in Kourou, French Guiana.
"Due to unfavorable winds at high altitude above the Guiana Space Centre, Arianespace decided not to start the final phase of the launch preparation operations," the French firm said.
The nearest launch window was now between 2200 and 2305 GMT on Wednesday "if weather conditions are favorable", it added.
The final flight of an Ariane, whose launches have punctuated life in Kourou for nearly three decades, was originally scheduled for June 16.
It was postponed the day before because of problems with pyrotechnical lines in the rocket's booster. The lines have since been replaced.
The final payload on an Ariane 5 is a French military communications satellite and a German communications satellite.
The arrival in 1996 of the Ariane 5, which was able to carry a far bigger load than its predecessor Ariane 4, allowed Europe to establish itself in the communication satellite market.
Ariane 5 flight VA261: weather delays launch
Tuesday, 04 July 2023 06:45
Europe’s Ariane 5 rocket is being prepared for its final launch, following the replacement of pyrotechnical transmission lines which delayed its earlier scheduled liftoff. Due to unfavourable weather Flight VA261 will now lift off no earlier than 5 July at 23:00 BST/00:00 CEST, pending suitable conditions for launch. You can follow live on ESA Web TV; transmission starts 30 minutes before earliest liftoff time.
