Nasa erhält Botschaft aus dem Weltall – aus 460 Millionen Kilometer Entfernung
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.”

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
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).

#NASA Set To Test #Space #Laser Comms At 240 Million Km With #Psyche #Asteroid
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.

#DSOC operations are planned for about two years, beginning roughly 20 days after launch. The 5.1-meter Hale #Telescope 
at Caltech’s Palomar Observatory* in San Diego County, #California, will receive the downlinked high-rate data from the DSOC flight laser https://www.jpl.nasa.gov/press-kits/psyche/dsoc

• 20 days after launch: DSOC calibration and commissioning phase is expected to begin, preparing the tech demo for operation.
• 50 days after launch: First expected contact opportunity between DSOC ground systems and the flight transceiver aboard Psyche.
• June 2024: First phase of this technology demonstration ends.
• January 2025: Second phase of the tech demo begins.
• October 2025: DSOC tech demo ends.

The Deep Space Optical Communications experiment will launch aboard the Psyche spacecraft, NASA’s first mission to the metal-rich asteroid Psyche. The experiment will test high-bandwidth optical communications to Earth during the first two years of the spacecraft’s journey to the main asteroid belt.
#NASA will host a media teleconference at 1 p.m. EDT on Wednesday, Sept. 20

#NASA July 12, 2023 #DSS23 started in February 2021 at the Goldstone, #California, #DSN Complex (with #OpticalCommunication
capabilities, which will be critical to communicate with #astronauts 
traveling to #Mars ). NASA cannot use #RadioFrequency communications to carry higher data rates like those required for Mars without increasing
the size of its antennas 
or power of its radio transmitters. Therefore, the Agency is developing #optical communications (use
of light as a means of transmitting information through #lasers) https://oig.nasa.gov/docs/IG-23-016.pdf
