Watch live: SpaceX launches Starlink satellite from Cape Canaveral on Falcon 9 rocket
Posted by Kelvin Dafiaghor in categories: drones, internet, satellites
Watch live coverage as SpaceX launches a Falcon 9 rocket with 23 second-generation Starlink internet satellites. Liftoff from pad 40 at Cape Canaveral Space Force Station is scheduled for tonight at 11:01 p.m. EST (0401 UTC). The first-stage booster, making its third flight, will land on the drone ship ‘A Shortfall of Gravitas’ about eight and a half minutes into the flight.\
Our live coverage from Cape Canaveral, with commentary by Will Robinson-Smith, will begin about an hour before launch.\

‘Teleporting’ images across a network securely using only light
Posted by Dan Breeden in categories: quantum physics, satellites, security
Nature Communications published research by an international team from Wits and ICFO-The Institute of Photonic Sciences, which demonstrates the teleportation-like transport of “patterns” of light—this is the first approach that can transport images across a network without physically sending the image and a crucial step towards realizing a quantum network for high-dimensional entangled states.
Quantum communication over long distances is integral to information security and has been demonstrated with two-dimensional states (qubits) over very long distances between satellites. This may seem enough if we compare it with its classical counterpart, i.e., sending bits that can be encoded in 1s (signal) and 0s (no signal), one at a time.
However, quantum optics allow us to increase the alphabet and to securely describe more complex systems in a single shot, such as a unique fingerprint or a face.

China launches large classified optical satellite towards geostationary orbit
Posted by Saúl Morales Rodriguéz in category: satellites
HELSINKI — China sent the classified Yaogan-41 optical satellite towards the geostationary belt Friday using the country’s largest launch vehicle.
The sixth Long March 5 rocket lifted off from the coastal Wenchang Satellite Launch Center at 8:41 a.m. Eastern (1341 UTC) Dec. 15. The China Aerospace Science and Technology Corp. (CASC) announced launch success around an hour later.

Electron returns to flight with successful launch of Japanese radar imaging satellite
Posted by Saúl Morales Rodriguéz in category: satellites
WASHINGTON — Rocket Lab successfully launched a Japanese radar imaging satellite on the first flight of its Electron rocket since a failure nearly three months ago.
The Electron rocket lifted off from the company’s Launch Complex 1 in New Zealand at 11:05 p.m. Eastern Dec. 14. The vehicle deployed its payload, the QPS-SAR-5 or Tsukuyomi-1 satellite for Japanese company iQPS, nearly 57 minutes after liftoff into a 575-kilometer orbit.
The launch was the first for Electron since a Sept. 19 failure during a launch of another radar imaging satellite for Capella Space. On that mission, the first stage performed as expected but the engine of the second stage appeared to shut down immediately after ignition, preventing it from reaching orbit.

Space X Falcon 9-rival from Rocket Lab returns to Space after a setback
Posted by Gemechu Taye in category: satellites
The launch marks the firm Electron rocket’s comeback after its failure in September, which resulted in the loss of a commercial Earth-observing satellite.
The 42nd mission signifies the return of Electron small rocket, bouncing back after a temporary pause prompted by a setback in September.

The SpaceX Falcon 9 rocket is the vehicle that brings satellites, Dragon cargo spacecraft and Crew Dragon spacecraft to orbit.
Among its many uses, SpaceX regularly launches Falcon 9 to bring its Dragon spacecraft to the International Space Station. Dragon made the first private spacecraft visit ever there in October 2012 and has run more than 25 cargo missions in the years since. Since 2020, SpaceX also used Falcon 9 for crewed missions to the ISS, on behalf of NASA and other customers.

Amazon tests space laser to transmit internet, aims 3,236 satellite web
Posted by Gemechu Taye in categories: internet, satellites
Project Kuiper seeks to deploy a swarm of small satellites into low Earth orbit (LEO) to enhance global broadband access, particularly to remote locations of the planet.
Amazon’s Project Kuiper initiative has marked a significant achievement with the successful in-orbit testing of a critical technology known as optical inter-satellite links (OISL).

NASA ’s Starling spacecraft are getting in formation: the mission team has spent the last two months troubleshooting issues and commissioning the four spacecraft, nicknamed Blinky, Pinky, Inky, and Clyde.
Pinky, Inky, and Clyde have successfully completed their propulsion system commissioning and have executed maneuvers to get into their swarm operations configuration, maintaining a range between 50–200 km apart. The three have also successfully demonstrated two-way communications with their crosslink radios in this closer proximity.
