NASA announced Monday that it had found one 19 million miles (31 million kilometers) from Earth spaceship used a state-of-the-art laser communication system to send high-definition (HD) video of a cat to Earth.
According to the news agency AFP, a 15-second video of a tabby cat named Taters is the first video broadcast from deep space, showing that it could be used to send humans to Mars. It is possible to transmit high data rate communications required for complex missions.
The video was shown on Earth using a laser transceiver on NASA’s Psyche probe. The spacecraft is on its way to find a mysterious metal-encrusted object between Mars and Jupiter.
In a video clip uploaded before the launch, the cat can be seen chasing a laser light on a couch. Test graphics overlays can also be seen in the video, including technical information about the Psyche spacecraft’s orbit, lasers and data.
When this video was sent, the spacecraft was 80 times the distance between the Earth and the Moon.
We just streamed the first ultra-HD video brought to you via laser from deep space. And it’s a video of Taters, a tabby cat.
This test will pave the way for high-data-rate communications in support of the next giant leap: sending humans to Mars. https://t.co/tf2hWxaHWO pic.twitter.com/c1FwybYsxA

These uncoded and near-infrared signals were received by the Hale Telescope at the Palomar Observatory in San Diego County, USA, and sent from there to NASA’s Jet Propulsion Laboratory (JPL) in Southern California.
Bill Klipstein, project manager of TechDemo at JPL, said: ‘One of the goals of this experiment is to demonstrate the ability to transmit broadband video over hundreds of thousands of miles. Nothing on the Psyche Probe creates video data, so we usually send packets of generated test data.’

He added: ‘But to make this momentous event even more memorable, we decided to work with the designers at JPL to create a fun video, showcasing the demo experience as part of the Psyche mission. Recorded.’
Traditionally Space Mission Sending and receiving data relies on radio waves, but working with lasers can increase data rates by 10 to 100 times.
It took 101 seconds to send the high-definition video to Earth at a speed of 267 megabits per second, the fastest of home broadband connections.
Ryan Rogalin, the project’s receiver electronics lead at JPL, said: ‘After actually receiving the video at Palomar, it was sent over the internet to JPL and the connection was slower than the signal from outer space.’
In response to the question why was the video of the cat sent? It has a historical connection, JPL said. When American interest in television began to grow in the 1920s, the statue of Felix the Cat was broadcast as a test picture.

NASA’s Laser Communication System: A Giant Leap towards High-Speed Data Transmission
In a groundbreaking experiment, NASA has successfully transmitted a high-definition video of a tabby cat named Taters from deep space to Earth using a state-of-the-art laser communication system. This achievement marks a significant milestone in the development of laser communication technology, which has the potential to revolutionize the way we transmit data across vast distances.
The Psyche Mission
The experiment was conducted using the Psyche spacecraft, which is on its way to explore a mysterious metal-encrusted object between Mars and Jupiter. The spacecraft is equipped with a laser transceiver that enables it to send and receive data through laser signals. In this test, the spacecraft was approximately 80 times the distance between the Earth and the Moon, making it the first video broadcast from deep space.
How it Works
Laser communication systems use invisible beams of light to transmit data between two points. According to NASA, lasers can increase data rates by 10 to 100 times compared to traditional radio waves [[3]]. In this experiment, the Psyche spacecraft transmitted the video signal to the Hale Telescope at the Palomar Observatory in San Diego County, USA, which then sent the signal to NASA’s Jet Propulsion Laboratory (JPL) in Southern California.
The Future of Space Communication
This experiment demonstrates the potential of laser communication systems to support complex missions, such as sending humans to Mars. The ability to transmit high-data-rate communications is critical for such missions, as it enables the transmission of large amounts of data, including high-definition video, in real-time.
NASA’s Laser Communication Technology
NASA has been at the forefront of laser communication technology, using lasers to send information to and from Earth [[1]]. The agency’s Space Communications and Navigation (SCaN) program has been working on developing advanced laser communication systems that can support future space missions.
Lasers in Space Exploration
Lasers are being used in various applications in space exploration, including remote sensing, laser ranging, and laser communication [[2]]. NASA’s Chris Smith explains how scientists put lasers to work to study Earth and beyond [[3]].
Conclusion
The successful transmission of a high-definition video from deep space to Earth using a laser communication system marks a significant milestone in the development of laser communication technology. This achievement has the potential to revolutionize the way we transmit data across vast distances, enabling faster and more efficient communication for future space missions.
