High-definition video of a cat transmitted 19 million miles through space using a laser

In preparation for Mars missions, NASA has transmitted a 15 second, high definition video of a cat chasing a laser pointer 19 million miles through space via laser. The cat in the video it is owned by one of the staffers at NASA.

In fact, the cat, 'Taters' lives with one of the employees of Nasa’s Jet Propulsion Laboratory (JPL).

The video was sent from NASA's Deep Space Optical Communications team's Psyche probe back to earth. The probe set off in October and is on a six year mission to visit an asteroid. The video was transmitted back to Earth on December 11.

“One of the goals is to demonstrate the ability to transmit broadband video across millions of miles,” Bill Klipstein, the tech demo’s project manager at JPL, told CBS. “Nothing on Psyche generates video data, so we usually send packets of randomly generated test data.

It is appropriate to send a cat video. I think you will agree because for a while, cat videos were dominating the world as were pictures of cats specifically funny pictures of cats. It was all pretty crazy and stupid but now they've managed to transmit this video over millions of miles through deep space, they'll be sure that they can do the same thing when the team travels to Mars.

Here is the Twitter X video (remember that it is embedded here. It might not work one day):

How important is available space in multi-cat homes in terms of cat welfare?

A study concluded that increasing the area for a group of cats confined to a specific area resulted in the cats playing more and being more active. They concluded that this indicated that they were more content and that extra space resulted in improved cat welfare. Note: the capitalised letters have been added for emphasis.

"In this study we examined the social and spatial behaviour in large groups of cats, as well as stress related body postures (using the Cat-Stress-Score) and if there were any changes within a stable group of 15 cats kept at different floor areas of 1 square meter, 2 square meters and 4 square meters PER CAT. Based on our results we conclude that increasing the area for group housed cats promote more play and general activity. Play can be an indicator of positive welfare for the cats."

They collected cats from shelters and used a fixed space in a research facility where the cats had varying amounts of space to themselves: one square metre, 2 m² and 4 m². The greater the space the more content they were is my interpretation of the summary of this research project.

How space affects a domestic cat's welfare

There has to be a commonsense appraisal of this because the result doesn't surprise me at all. This is because an individual male domestic cat probably would naturally require an area up to around 50 acres. It will vary and it might be a smaller at about 10 acres and for female cats it will be smaller still but the space that they naturally require is going to be much larger than that they are allowed if they are full-time indoor cats. And even if they are allowed outside into a garden enclosure it is still unnaturally small.

In the study they were confined to a much smaller area and when allowed to expand into a larger area they became more content which, as mentioned, was predictable.

The point of this very brief discussion is that the amount of space allowed to a domestic cat can have an impact upon their stress levels and therefore their contentment and as a result their general welfare and health.

This is a point that needs to be remembered by people who desire to look after several cats in perhaps a small house or even an apartment.

Of course, domestic cats are adaptable and they will adapt to the smaller area and it depends on the relationship between the cats but it is better that they don't need to adapt as there is always this underlying instinct to live within an area of up to around 50 acres. This figure of up to 50 acres comes from other research studies. There have been many on this topic.
