NASA recently established a new tool to overcome signal disruptions - "High Rate Delay Tolerant Networks"(DTN). Spacecraft communication using a series of relaying satellites that circle a planet; experts estimates that up to 95% of the data is not transmitted back to earth and may never be recovered.- Snopes The move to a more connected space, internet like system will make space communication more efficient, secure, safe and reliable. Introduced in 2003, delay- tolerant networks(DTN) have proved most useful in deep space communication. DTN is built on existing technology by employing a laser or optic communication to send Information between spacecraft, astronauts and earth. Data is modulated to be placed within the laser beam before it is transmitted between devices...... "High Rate DTN" is designed with speed, security and efficiency to keep up with data rates of newer laser and radio frequency communication systems.... In 2013, NASA used lasers to send an image of Mona-Lisa to the moon and back to earth at the Lunar laser demonstration. A common approach used to address delays and distruptions is via the use of a store and forward mechanism. A version of DTN is in operation on the international space station. More recently, it has been proposed: the enhanced disruption-tolerant network called EDIFY(Ehanced Distruption and Fault Tolerant Bundle Delivery). In the EDIFY architecture, there are several types of nodes regular DTN nodes, DTN name registrar(DNR), etc. Excessive round trip time or high loss probability requires more attention. The DTN architecture is actually to support the objectives of the Artimes mission. Artimes programme is a series of program. Artemis 1, mission has already been completed - In late 2022. Uncrewed test flight, orbiting and flew beyond the moon. Artimes 2, will be crewed flight beyond the moon which will take humans the farthest they have been in space. Artimes 3, will be the first crewed Moon landing mission since Apollo 17 in 1972 to be followed by Artimes 4, 5, etc. NASA's goal is to go there now to stay permanently. It will involve establishing bases both in the Lunar orbit and on the Moon surface by the middle of the decade. (Royal Museum Greenwich). - Alfred, Spintex.

NASA - National Aeronautics and Space Administration’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 milestone is part of a NASA technology demonstration aimed at streaming very high-bandwidth video and other data from deep space – enabling future human missions beyond Earth orbit. “This accomplishment underscores our commitment to advancing optical communications as a key element to meeting our future data transmission needs,” said NASA Deputy Administrator Pam Melroy. “Increasing our bandwidth is essential to achieving our future exploration and science goals, and we look forward to the continued advancement of this technology and the transformation of how we communicate during future interplanetary missions.” The demo transmitted the 15-second test video via a cutting-edge instrument called a flight laser transceiver. The video signal took 101 seconds to reach Earth, sent at the system’s maximum bit rate of 267 megabits per second (Mbps). Capable of sending and receiving near-infrared signals, the instrument beamed an encoded near-infrared laser to the Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California, where it was downloaded. Each frame from the looping video was then sent “live” to NASA Jet Propulsion Laboratory in Southern California, where the video was played in real time.

How might lasers revolutionize deep space communications? NASA will test high-bandwidth laser (or optical) communications for the first time beyond the Moon with a pioneering technology demonstration called Deep Space Optical Communications (DSOC). If successful, this kind of laser communications technology could be used to transmit large volumes of data – such as streaming video and higher-resolution science observations – from robotic spacecraft and from future astronauts exploring Mars. DSOC is attached to NASA’s Psyche spacecraft and will send and receive signals during the first two years of Psyche’s six-year journey to the metal-rich asteroid of the same name. During its demonstration period, DSOC will not be transmitting Psyche data, but rather its own set of data. The experiment involves a transceiver on the spacecraft along with two ground stations – one at the Jet Propulsion Laboratory’s Table Mountain facility and the other at Caltech’s Palomar Observatory. Psyche and DSOC are expected to launch in October 2023 Learn more about the DSOC experiment at https://lnkd.in/gSsdcDEj

NASA - National Aeronautics and Space Administration is embarking on a mission called #Starling, where they will be sending a team of four CubeSats into orbit around Earth to test their ability to cooperate autonomously without real-time updates from mission control. This mission is crucial for the future of deep space missions, where more complex and autonomous spacecraft will be necessary. #cubesat #nasa #NASAStarlingProgram #UnitedStates

"In October 2023, NASA launched its long-awaited on-again, off-again Psyche mission. The spacecraft is on its way to study the metal-rich asteroid 16-Psyche, an M-type asteroid that could be the remnant core of a planetesimal that suffered a collision long ago. But understanding the giant, metal-rich asteroid isn’t the Psyche mission’s only goal. It’s also testing a new laser communication technology. The new system is called Deep Space Optical Communications (DSOC.) DSOC uses infrared lasers to communicate between spacecraft and ground stations. In this first experiment, the Psyche spacecraft communicated with the Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California. Psyche was beyond the Moon when it communicated, and the distance between the spacecraft and the Hale Telescope was nearly 16 million km (10 million miles.)" #space #communications #optical #lasers

NASA has achieved a groundbreaking feat by sending a laser-beamed message from nearly 10 million miles away to Earth in just 50 seconds. This technological advancement, using NASA's Deep Space Optical Communications (DSOC) experiment on board the Psyche spacecraft, could enable high-speed streaming and communication with Mars in the future. The DSOC system is capable of beaming information 10 to 100 times faster than current space communications equipment. This achievement paves the way for higher-data-rate communications and supports humanity's goal of sending humans to Mars. #NASA #DeepSpaceCommunications #MarsStreaming

A laser communications experiment flying aboard NASA - National Aeronautics and Space Administration ’s Psyche mission has beamed back a video to Earth from nearly 19 million miles (31 million kilometers) away — and the short clip stars a cat named Taters. It’s the first time #NASA has streamed a video from deep space using a laser. In the ultra-high definition video, the playful orange tabby cat chases, of all things, the elusive red dot from a laser pointer as it moves across a couch. The cat video was transmitted to Earth from a flight laser transceiver as part of the Deep Space Optical Communications experiment, or DSOC. The technology could one day be used to quickly transmit data, imagery and videos as humans push the limits of space exploration by venturing to places like Mars. The 15-second video was encoded in a near-infrared laser and beamed from the Psyche spacecraft to the Hale Telescope at the California Institute of Technology’s Palomar Observatory. The video was downloaded at the observatory on December 11, and each frame was streamed live at NASA’s Jet Propulsion Laboratory in Pasadena, California. The Video NASA’s Laser Communications Experiment Streamed From Deep SpaceVideo The Video NASA’s Laser Communications Experiment Streamed From Deep Space At the time of the transmission, the distance between the Psyche spacecraft and Hale was 80 times the distance between Earth and the moon. It only took 101 seconds for the laser to each Earth. https://lnkd.in/dhJrQsUt
