At my old uni they were still using windows 95 on some machines, because when they were made that is the OS they used. Now they are still being used and its cheaper to keep a Win95 OS than it is to get new machine or redevelop the software for anything newer.

[@guss77]

@@Azivegu until eventually it will become too expensive to maintain a 30 years old machine than to do the whole thing from scratch - but then it will be after a failure so there'll be a time pressure, so the project will be rushed, so the result will be bad, so it will be patched again under budget and under time pressure, the product getting worse from patch to patch. This story had been repeated over and over again. The alternative is to invest some money every 5 years to modernize and improve - in the long run you get better results for less money.

@ Windows 95 won't even install on a modern PC you can buy in the store now. How do you deal with hardware failures? Probably the only logical thing to do is to run the whole thing virtualized, but it really sounds like a bad idea for long term maintainability.

[@Azivegu]

@@guss77 I don't disagree, but it was an instrument to test the pressure a rock could handle for a geology department that cost something like €5 million. If the top were somehow to come of, the cylinder inside of it would be shot at such a speed it enter into a sub orbital trajectory. So they'll keep using it as long as they can.

“Inside a drop tower simulating zero-g **effects**”

[@boonies4u]

yeah, thankfully the person they're interviewing clarified

[@Jonassoe]

If you want to be technical, the drop tower experiments are weightless (or "experiencing microgravity") for the same reason that astronauts on the space station are - they're in freefall in Earth's gravity field. It doesn't "simulate" zero-g effects any more than actually being in space does, so I think it's a bit of an arbitrary distinction.

[@lits0_042]

Jonassoe it’s the idea of simulating the effects... the actual environment of “zero-g” or even the term “microgravity” is technically not even happening. The astronauts on the ISS experience nearly the same amount of gravity as everyone else on Earth. As you said, they are in a “weightless” environment. A constant free-fall spinning around the globe.

[@boonies4u]

@@lits0_042 if something is in free fall at terminal velocity it is zero-g, it literally means zero acceleration

[@XLostGamer]

@@Jonassoe the problem here is that it still in gravity these test are flaud unless they can remove gravity

[@siggyincr7447]

Shame they didn't go more into depth about the plans for the new system. If I'm understanding it correctly they'll accelerate the experiments on a powered elevator or "slider" with exactly the same acceleration as gravity produces to negate it's effects. Should be far more efficient as creating a vacuum in that large of a chamber must reck up one hell of a power bill. The only thing I''m surprised about is that this hasn't been done in an abandoned mine shaft. Some of them go far deeper than you could practically build a tower.

[@ninjafruitchilled]

I don't really get why they need to evacuate the whole tower over and over. Why not just have an airlock or some such in the sections where the experiments go in and out, so you only have to evacuate that one small chamber repeatedly?

Use an airlock to keep the tower tube evacuated while the launch site is serviced and prepped. Then evacuate that smaller area more quickly before opening the airlock hatch wide enough to make the tower accessible. Then close the hatch again when complete to access the experiment while preserving the vacuum. Quicker turn around. Not much of an upgrade needed.

Jumping high just to get those doses of micro gravity...

[@bueb8674]

To those wondering how it can be weightless while going up; after it's 'shot', it starts with 165km/h, decelerates and reaches 0km/h at the top, then accelerates to 165km/h by the time it's back at the bottom. The only force acting on it _is_ the acceleration of gravity and thus it's in free-fall the whole time. If you were to plot the velocity over time, it would be a perfect parabola changing at 9.8m/s^2. To put it into a relatable feeling, think when you're jumping on a trampoline, you feel 'weightless' the whole time you're in the air, even while moving upward. Or in an elevator going up, that brief moment when it stops, you may almost lift off the floor. Like that but it launches you at 30g so you go flying up

Question: why they don't add a sealed door lock above the room where the capsule is managed, so they can start pumping out air from the tower above, while refilling the deceleration chamber and setting up the capsule?

Guys, here is the paper on the next gen tower they are building that was in the video. www.researchgate.net/publication/270344841_Concept_for_a_Next-Generation_Drop_Tower_System They basically use guided electro-magnetic linear drives (like in roller coasters) to sort of have the capsule inside a capsule in an elevator which goes through air (not in a vacuum!) with enough force that the capsule inside the elevator never touches the walls effectively making it drop as fast as if it would have dropped inside a vacuum tube like i the old system.

A carbon fiber cord looped over a wheel at the top and strung to the bottom to a lower wheel, then back up with the test capsule as a joiner of the ends of this cord, driven concurrently by 2 electric motors positioned at both wheels with the motors controlled by an accelerometer's data transmitted from within the capsule, might offer the air drag compensation and eliminate the need for a vacuum. The motors might offer some boost to the hydraulic drive of the upward phase, or even provide all the initial upward thrust when doing experiments that will not permit the high g forces of the hydraulic system.
