SuitSat-1: A Spacesuit Floats Free
Explanation: A spacesuit floated away from the
International Space Station 15 years ago, but no investigation was conducted. Everyone knew that it was pushed by the
space station crew. Dubbed
Suitsat-1, the unneeded Russian
Orlan spacesuit filled mostly with
old clothes was fitted with a faint
radio transmitter and released to orbit the Earth.
The suit circled the Earth twice before its
radio signal became unexpectedly weak.
Suitsat-1 continued to orbit every 90 minutes until it burned up in the
Earth's atmosphere after a few weeks.
Pictured, the lifeless spacesuit was photographed in 2006 just as it
drifted away from
space station.

And since we now know its not allowed/possible to wash clothes in space,
it would have been a very grimy set of clothes inside indeed !?

Re-entry would have had something of a scouring effect, perhaps as high as two micro-Zwickys.

This is weirdly entertaining. I have so many questions now. Are spacesuits so ubiquitous that they can just jettison one for fun? Or did they intentionally bring along an extra spacesuit? Did they get in trouble for doing it? Did they sneak some vodka onto the ISS and were just drunk? And finally... just how smelly were those clothes?

The suit had reached it's end of useful life (probably along with some worn out clothes - or can clothes really not be effectively or economically washed in space, with or without water?) - and was repurposed to end life doing something of some scientific value.

So, is a Zwicky a made-up unit, used here solely for comedic effect? I searched in vain to find a definition. It would no doubt be based on the work of famous astronomer Fritz Zwicky -
https://en.wikipedia.org/wiki/Fritz_Zwicky.
EDIT: ok, it's humourous. I found this from
https://stargazerslounge.com/topic/1605 ... be/page/2/:
One of his colleagues said that 'The Zwicky' should be adopted as a unit of abrasievness, to which another replied that the micro-Zwicky would already exceed the highest know abrasiveness on earth! Walter Baader thought Zwicky wanted to kill him.

This spacesuit floats free picture reminds me of something similar not 15 years ago but some 3 or 4 years ago about a spacesuit (empty as well) that was seen driving away from Earth in a red convertible car. I think it belonged to the Elon Musk Space Corporation or something. Wonder what happened to that?

<<Fritz Zwicky (born
February 14, 1898) is remembered as both a genius and a
curmudgeon. One of his favorite insults was to refer to people he did not approve of as "spherical bastards", because, he explained, they were bastards no matter which way one looked at them. German colleague Walter Baade claims to have been accused by Zwicky of being a Nazi, and falsely staged complaints that he "feared" Zwicky. Unknown to the public was that Baade was fearful, because he had named a galaxy after himself that was discovered by Zwicky. Edwin Hubble corrected this injustice and the galaxy was catalogued as a Zwicky galaxy. Zwicky & Baade pioneered and promoted the use of the first Schmidt telescopes used in a mountain-top observatory in 1935. In 1934 he and Baade coined the term "supernova" and hypothesized that supernovae were the transition of normal stars into neutron stars,as well as the origin of cosmic rays.
Zwicky was skeptical of the expansion of space in 1929, because the rates measured at that time seemed too large. It was not until 1956 that Walter Baade corrected the distance scale based on Cepheid variable stars, and ushered in the first accurate measures of the expansion rate. Cosmological redshift is now conventionally understood to be a consequence of the expansion of space; a feature of Big Bang cosmology. In support of this hypothesis, Zwicky started looking for supernovae, and found a total of 120 by himself (and one more, SN 1963J, in concert with Paul Wild) over 52 years (SN 1921B through SN 1973K), a record which stood until 2009 when passed by Tom Boles. Zwicky did his laborious work, comparing photographic plates with the human eye, which is far more challenging and difficult than Boles accomplished using modern technology for his record.>>

It's in an orbit around the Sun with a 1.5 year period, ranging in distance from about Earth's orbit to somewhat beyond Mars's orbit.

So anything just casually tossed out the space station door/airlock will burn up in a few weeks?

Depends on the shape and mass.

Yes, a brilliant gesture by Musk.

The spacesuit in Elon Musk's "space Tesla" was exactly empty, because there was a mannequin inside.
Got to say I loved that piece of cheekiness from Elon Musk. Too cool! (Yes, I know I'm being childish here, but I can't help it, I loved it.)

The fact that the Tesla was aimed (sorta) at Mars, and missed by about half a universes worth might be of some
concern for those heading for Mars later on - unless someones navigation skills have improved somewhat. !
The official reason was that the motors burned for much longer than expected. (?).
But you'd think that should have come into the calculations.

Almost all trash in the ISS is ejected. It's the most efficient, cost-effective way of getting rid of it. And this spacesuit was obsolete and of no further use. So it was, in fact, trash. Nice they found a way to stretch one last little bit of value from it.

Hmm, what about the loss of some oxygen due to the ejection process. Or maybe that's deliberately minimized enough to be a non-issue.

I think it's a non-issue. The amount lost is trivial compared with other places it is lost. Oxygen is constantly being delivered to the ISS and made from water to make up for that. I expect the space occupied by an obsolete space suit is more valuable than the amount of oxygen inside it.

Actually, I think I disagree with your take. It would be very valuable for the Russians to get a used space suit back and examine it under a microscope (literally and figuratively), do materials tests, etc., since they know
exactly what it was exposed to, when, how used, maintained, etc. In fact, IF they regularly returned such things, it’s the one set of experiences they could regularly ‘sell’ on the open market- especially to China. Yet they just threw it away. The reasons?
They had no way to return it using only Soyuz, and obviously refused to ‘request’, or barter, for space on a returning Dragon capsule; probably due to pride.
You that image was first released, you can just bet that there were groans at the Russian space suit manufacturer….as well as those in the foreign ministry and certain people at top of Roscosmos who realized it was valuable property and hard-won experience being thrown away; all because some politico in the Russian chain of command- maybe even Rogozin or Putin; or, someone
afraid of how Rogozin or Putin would react- to a request to bring down the suit on an American Dragon.

If in fact such "wear and tear" data were valuable, I'd imagine that similar data had already been collected and analyzed long ago both in orbit and back on earth.
