Nasa erhält Botschaft aus dem Weltall – aus 460 Millionen Kilometer Entfernung
#dsoc
Transporting #data 📶 at rates up to 100 times higher than radio frequencies by #laser https://www.jpl.nasa.gov/news/nasas-laser-comms-demo-makes-deep-space-record-completes-first-phase/
Are 7kW of laser power enough to allow communications at distances similar to that between Earth and Mars at their farthest? And at speeds 100x that of equally powered radio transmissions?
#NASA seems to have proven it is:

“Our hybrid antenna has been able to successfully and reliably lock onto and track the #DSOC downlink since shortly after the tech demo launched,” said Amy Smith, #DSN deputy manager at JPL. “It also received #Psyche's radio frequency signal, so we have demonstrated synchronous radio and optical frequency deep space communications for the first time.”

2023 was a big year for laser communications at #NASA! It saw the first bi-directional laser communications relay with the #ISS performed by the #LCRD mission (at over 1 Gbps), a 267 Mbps downlink from deep space (19 million miles away) by the #DSOC mission, and 200 Gbps throughput on a laser link with a LEO orbiting spacecraft by the #TBIRD mission.

Psyche – from Greek mythology to Greek mountain tops
ESA will participate in NASA's Deep Space Optical Communication (DSOC) demonstration in 2025.
To select a suitable site for ESA’s ground infrastructure, the team searched for the most suitable optical telescopes in Europe; the 2.3 m Aristarchos telescope, located at an altitude of 2340 m at the Helmos Observatory in Greece, checked all the necessary boxes.

📆 December 19, 2023 #Caturday at #NASA - they streamed a #cat 🐈 video from #DeepSpace using a #laser.
“Despite transmitting from millions of miles away, it was able to send the video faster than most broadband internet connections” https://edition.cnn.com/2023/12/18/world/nasa-space-laser-cat-video-scn/index.html
💡 NASA usa le comunicazioni ottiche via laser per trasmettere i video
Grazie al laser, la NASA invia il primo video in streaming da oltre 19 milioni di chilometri dimostrando il potenziale delle comunicazioni ottiche per le future missioni spaziali umane

Brilliant. Our first long-distance space laser communications test is a cat video! Hopefully the aliens aren't dog lovers. 😸

#NASA’s Deep Space Optical Communications experiment beamed an ultra-high definition streaming video on Dec. 11 from a record-setting 19 million miles away (31 million kilometers, or about 80 times the Earth-Moon distance).
The video signal took 101 seconds to reach Earth, and was sent at the system’s maximum bit rate of 267Mbps.

On 📆 Dec. 4, the mission turned on #Psyche’s twin cameras 📷 and retrieved the first images – a milestone called “first light.” "In 📆 2026 we’ll take test images of #Mars 🔴 during the #spacecraft’s flyby" https://www.nasa.gov/missions/psyche-mission/nasas-psyche-delivers-first-images-and-other-data/
#Psyche sees first light!
Although still far from its 2029 encounter with the asteroid, the spacecraft opened its eyes (twin cameras) and captured a total of 68 images, all within a star field in the constellation Pisces.
The spacecraft has already set a record by using a laser beam to communicate with Earth in an experiment called Deep Space Optical Communications (#DSOC).

Mission
NASA will test a brand new #communications system with the Psyche mission, aiming to improve data transfer speeds significantly. This is part of NASA's #DeepSpace Optical Communications (#DSOC) test, which will place a transceiver equipped with a laser transmitter and a camera to send lasers to Earth and also receive laser communications from the home planet.
