After a series of delays due to Hurricane Ida and "an issue found during a pre-launch ordnance circuit continuity check", for the first time in almost 11 months, a United Launch Alliance (ULA) Atlas V rocket took off from Florida's Space Launch Complex 41 (SLC-41), Cape Canaveral Space Force Station (CCSFS), on Sunday at 8:47 a.m. EDT (1247 UTC).
This marks the second launch of the year fo XRISM satellite launches to study the universe in different colors of X-rays

On Sept. 6, a new satellite left Earth; its mission is to tell us about the motions of hot plasma flows in the universe.
Launched from Tanegashima Space Center in Japan, the X-Ray Imaging and Spectroscopy Mission (XRISM) satellite will detect X-ray wavelengths with unprecedented precision to peer into the hearts of galaxy clusters, reveal the workings of black holes and supernovae, as well as to tell us about the elemental makeup of the universe.
XRISM, pronounced "crism," is a collaborative mission between the Japan Aerospace Exploration Agency (JAXA) and NASA, with participation by the European Space Agency.

SpaceX's Starship to remain grounded after explosion probe
Sunday, 10 September 2023 09:02 Write a comment
SpaceX's Starship, the most powerful rocket ever built, must remain grounded while Elon Musk's company completes dozens of corrective actions to prevent a repeat of the spectacular explosion that marred its first orbital test flight, regulators said Friday.
The 63 steps include "redesigns of vehicle hardware to prevent leaks and fires, redesign of the launch pad to increase its robustness," Viasat researching more portable satcoms terminals for dismounted soldiers

Virgin Galactic notches fourth spaceflight in four months

Virgin Galactic on Friday announced it had sent three paying customers on an hour-long journey to space and back, racking up its fourth successful flight in as many months.
The private astronauts aboard the Galactic 03 mission were among the first people to buy their tickets from the company founded by British billionaire Richard Branson in 2004.
American real estate entrepreneur Ken Baxter, South Africa-born conservationist Timothy Nash, and British engineer and entrepreneur Adrian Reynard took their places aboard the rocket-powered spaceplane VSS Unity, along with Virgin Galactic's astronaut instructor Beth Moses.
"What a thrilling day for our three new private astronauts and the entire team at Virgin Galactic," said CEO Michael Colglazier.
Scientists study distributed satellite cluster laser networking algorithm with double-layer Markov DRL architecture
Friday, 08 September 2023 16:31 Write a comment
With the development of satellite networks, space-air-ground integrated networks, and the Internet of Things, the future giant constellations, high-resolution Earth observation, human-crewed spacecraft, space stations and other space-based information systems have put forward an increasingly urgent demand for large-capacity space networking and information transmission.
The space distributed satellite cluster (DSC) overcomes the resource constraints and technical bottlenecks of single-satellite platforms by using multiple heterogeneous satellites in the same orbit to cooperate with distributed payloads to achieve large-capacity high-speed networking and information transmission and exchange in space, providing an effective solution for the above-mentioned needs.
The high-speed variation of relative positions of multi-satellites in the same orbit and the visible state constraints of satellite-borne optical phased array antennas cause the topology of DSC to be dynamically time-varying and intermittent link interruptions. It is necessary to solve the problems of rapid topology reconstruction and dynamic continuous networking under these two situations.
