Sometimes you get answers to questions you never knew you had asked... When I worked in television, we always had to move our dish to a different satellite for the overnight feed when we went off the air. We always had to sync with LCS-1 before switching to the new satellite feed. I was 0 days old today when I learned what in the hell LCS-1 really was. Thanks for the lesson! :)
Aint that the truth, I didn't even see this in mu notifications, just seen it while browsing, and yep, sure enough, had I thought to ask, or knew of its existance, I def would have looked into this!
It's one of those things that makes a lot of sense when you learn about it, and understand it is a most critical thing necessary for other things; but usually don't bother to do so because it's overshadowed by those other things it supports and enables.
Well all you had to do was ask 🤷🏻♂️ At one job they kept saying this acronym and anytime I asked what it meant no one seemed to know, I'm like how are you training me if you don't even know what those letters stand for? I looked it up on Google and found out what it was and everything made more sense.
Huh, now that you mention it none of our tins are tin anymore. Our sewing tins, our tin cans, our tins of soup or cookies, our tin foil etc. All aluminium but we call it tin
Fascinating. I was familiar with the two Echo satellites launched in 1960, but not with LCS-1. The Echo satellites were 30m inflated spheres made of aluminized mylar, and were designed to test radio communication by reflection, and not for calibration. Both satellites re-entered in the late 1960s.
Here at Space Fence, we use both LCS spheres and a couple other objects for radar calibration. We track from LEO all the way to GEO. At low orbit we can track extremely small objects! All thanks to MIT-Lincoln Labs

I've always wondered how they know if the instruments are reading information correctly. Cool to know we have something that they can test instruments on.
ESA have an Earth observation satellite called Aeolus that measures wind speeds in our atmosphere. They have some ground based equipment too to make sure that what the satellite is measuring from space is actually the same as the conditions measured from the surface.
@@massimookissed1023 ah! I thought weather stations just observed their areas with ground based equipment. Though I do know that they have a super computer in wyoming. That the information from weather collected by satellites goes to! I think it's to observe weather patterns and calculate weather into the future.
@@pyrogotz5076 commercial aircraft also gather weather data for places that model the atmosphere and try to predict weather. They can collect temperature and pressure readings, maybe humidity too, and possibly windspeed (measured at the plane vs plane's speed from GPS). All those flights can gather data from locations that ground-based monitoring stations can't access.
@@pyrogotz5076 the vast majority of global climate data is from satellites. The earth is huge and there's still tons of remote areas that don't have good, reliable weather stations.
Thank you, Hank, you guys keep covering really important science topics that do not get the coverage they should. At the same time you cover the flash stuff too as well as anybody (and better than all but specialists). I guess you guys are high-quality entertainment for the thinkers.
This whole video read so much like a Pin-of-the-Month announce ment to me lol. I was waiting the whole time to see what the pin design was, I was really expecting to buy it
It might be worth noting that later, Lincoln Laboratory built and launched a series of active communications satellites into orbit. The LES (Lincoln Experimental Satellite) series were far more reliable than almost any others built by for-profit defense contractors. The last in the series, LES 8 and LES-9 were launched into synchronous altitude* in 1976 and in the almost sixty years since then, they never failed. *Synchronous altitude but not geosynchronous. An observer on earth sees each of these satellites moving in a figure eight pattern repeating daily.
I’ve tracked LCS-1 (1361) and LCS-4 (5398) numerous times in my radar career. There are several different calibration satellites available. AJISAI (16908) is a mirror ball with laser reflectors.
"It's own kind of party" It's kinda like the audio tech's party. Everyone's up and in front cheers for the heroes on the stage. Backstage have their own party.
Imagine if a nearly perfectly round hollow metal sphere, perhaps mildly damaged by collisions, fell into our solar system. The paranoia that it would create would be extreme even if it essentially was merely a calibration sphere that got lost to its original purpose.
I have had a similar thought myself as an idea for a science fiction book or movie. What if something entered our solar system from outer space but it was totally mundane, i.e. a spanner or a sheet of metal.
It wouldn't be a case of what it is, but what it means. Considering the time it would take it to get here. It would mean they were probably at roughly a comparable level to us, when we launched ours, tens of thousands of years ago. What their technology could be today, could be godlike to us.
@@lordgarion514 careful: there is no guarantee that technology and economies can grow forever. A civilization millions of years older than ours may be perfectly conceivable in its technological superiority over us.
Why am I only hearing about this legendary ex beercans now? So many tiny little barely formed questions floating around the skull just got lightbulbed! Thanks Hank😎
Almost as impressive as the inanimate carbon rod that saved the very lives of the Spcae Shuttle mission crewed by Race Banyon, Buzz Aldrin and Homer Simpson!
April Fools' prank idea: discretely swap LCS-1 and LCS-4 and send them along each other's trajectories. Scientists will be confused when they look for one LCS and find that it has the light reflection pattern of the other
Probably nobody. For reference, it appears about the same size as Pluto from Earth, which is quite difficult to spot. It would be nearly impossible to spot unless you knew where to look, or had an extremely powerful telescope.
It's so poetic to me that what is arguably the least interesting of humankinds space tech is one of the most important. Whenever you are feeling small or unappreciated remember that an unimpressive space marble has been and continues to be one of the most important tools for space exploration since it first began 💕💕.
When I was at JPL,we needed to precisely calibrate a radar we’d built. We had a local firm make a 12” aluminum sphere and took the whole kit and caboodle out to Goldstone in the Mojave desert, hoisted it with a tethered balloon, and proceeded to do exactly that. Fun!
Now that I think about it, even if an asteroid or something passes by Earth and doesn't collide, it will probably bring down a lot of the space debris.
@1:59 - Wouldn't an aluminium cube with comparably smooth surfaces actually have a larger radar cross-section and "look bigger" when seen face-on rather than from a corner what with deflecting the radar rather than reflecting it back to the source?
Imagine if an alien civilization discovered this, long after we've all destroyed ourselves in the next few decades. They'd probably conclude it was a religious artifact.
Measurements are integral to science, and calibration of measurement devices is integral to their efficacy. This gave me the same jolt as the Veritasium video about measuring very small things.
I have a _bone_ to pick with you, Hank. Five years ago, you and John guest hosted Good Mythical Morning, and it was fantastic. But _when_ are you going to get Rhett and Link to guest host an episode of SciShow!?
As a young boy, I dreamed of being a one-meter hollow aluminum sphere, sent into a circular orbit around the Earth. But tonight I say, we must move forward, not backward; upward, not forward; and always twirling, twirling, twirling towards freedom!
So wait, conspiracy theorists claim the “Black knight” object has been floating in orbit for 13,000-to this day (despite being debunked numerous times) but I’m just now learning of this aluminum sphere?
The first (and only) British-built and launched satellite, Prospero, also known as the X-3, was launched in 1971. It is still up there. If only we had made it spherical...
So this thought comes up. Does time dilation drastically change with the distance from the star with planets moving at different rates of speed and velocity and or oval orbits that slingshot around the sun. Would orbital mechanics limit the rate of time dilation keeping uniform velocities of stars and distance ?
My question after seeing pictures of the NACA sphere and the pseudo sphere is, is it really a Mylar fabric with aluminum skin, as a balloon? And if so, was it inflated once in orbit by a gas, or was it a foam? It could explain why there is a difference in reflectivity.
