They did it with an advanced instrument called a flight laser transceiver and the video signal took 101 seconds to reach Earth. The finest part of all of it? Its a video of a feline going after a laser.
NASA just made history. The space company sent a video from almost 19 million miles away at a maximum bit rate of 267 megabits per second (Mbps)– much better than the web Im presently composing on.

The very first deep space transmission (” first light” as NASA calls it) was beamed on November 14 from the Psyche mission. The Psyche mission represents an exploration to an asteroid plentiful in metals, situated in the asteroid belt in between Mars and Jupiter.
” Despite transmitting from countless miles away, it had the ability to send the video quicker than many broadband internet connections,” said Ryan Rogalin, the projects receiver electronic devices lead at JPL. “In truth, after getting the video at Palomar, it was sent to JPL online, and that connection was slower than the signal coming from deep area. JPLs DesignLab did an amazing job assisting us display this innovation– everybody likes Taters.”
In general, NASA has downloaded 1.3 terabits of information in about a month of testing. For comparison, the Magellan mission to Venus sent 1.2 terabits throughout its whole objective from 1990 to 1994.
” When we achieved first light, we were delighted, however also mindful. This is a new innovation, and we are explore how it works,” said Ken Andrews, task flight operations lead at JPL. “But now, with the help of our Psyche colleagues, we are getting used to dealing with the system and can lock onto the spacecraft and ground terminals for longer than we could formerly. We are finding out something brand-new during each checkout.”
NASA gradually increased the download speed of the transmission to 62.5 Mbps, 100 Mbps, and finally to 267 Mbps. Using lasers, it handles to achieve these speeds from a massive 31 million kilometers away (or about 80 times the Earth-Moon distance).
However whats truly cool, besides the content of the video, is the speed at which it was sent out.
This is where Taters video comes in. Taters is an orange feline and the family pet of a JPL worker. The video reveals Taters chasing after a laser pointer, with overlayed information of numerous NASA missions. Taters heart color, rate, and breed are also on display screen.

Theres a historical reference here, too. In 1928, a small statue of Felix the Cat (a popular animation character) was utilized in test broadcast transmissions.
” This achievement highlights our commitment to advancing optical communications as a crucial element to meeting our future data transmission needs,” said NASA Deputy Administrator Pam Melroy. “Increasing our bandwidth is important to accomplishing our future exploration and science goals, and we look forward to the continued advancement of this innovation and the change of how we interact during future interplanetary missions.”
The video, featuring a cat called Taters, marks a crucial minute in our area exploration. Checking out the much deeper parts of space isnt practically constructing engines and life assistance, its also about interaction. If we desire to explore the solar system (and ultimately, go beyond that), we require ways to beam details to and from Earth.
Changing how we see the solar system
The ramifications for future missions are considerable. Picture astronauts on Mars able to send out high-resolution video back to Earth, or probes at the external edges of our planetary system transmitting in-depth data much faster than ever before. This might dramatically change our understanding of area and our location in it.
This innovation might reinvent how we send out and receive data from deep space. Standard radio waves have served us well, however laser communication provides a much higher information rate. This suggests more comprehensive images, more data from clinical instruments, and even the possibility of high-definition video streaming from distant planets or moons.
The success of this laser communication test is a step towards making these possibilities a truth, however its still early days. As NASA continues to finesse the innovation, new avenues for area expedition are opening up– but theres still a method to go.
The video, including a cat called Taters, marks a crucial minute in our space expedition. The video shows Taters chasing after a laser guideline, with overlayed data of numerous NASA missions.” Despite sending from millions of miles away, it was able to send the video much faster than many high speed broadband web connections,” stated Ryan Rogalin, the projects receiver electronic devices lead at JPL. “In reality, after receiving the video at Palomar, it was sent out to JPL over the internet, and that connection was slower than the signal coming from deep area. Picture astronauts on Mars able to send out high-resolution video back to Earth, or probes at the outer edges of our solar system transmitting detailed data quicker than ever before.
