Iss Definition and 65 Threads

Hello I have a question regarding the ISS (international space station) For about a year now, I've been using free youtube tutorials to teach myself how to 3D model for free. Just something I'm doing to educate myself. As sort of an "exercise" I'm 3D modeling an interplanetary cycler ship...

Does the ISS remain oriented with the Earth? I.e. it rotates 360 degrees every 24 hours, or is it fixed with the stars? If the latter, there should be a time when it's visible end-on. I looked it up but did not find the deets. I guess that what the gyros are for.

I tried a Google search on this question, and got mixed results. I was curious if satellites (and the ISS) have to burn power to stay pointed at Earth, or if any were able to use passive tidal locking instead. I did find that satellites in geosychronous orbit are less likely to use tidal...

Hello, I am new in physics but I really like it so far. I have a question about hydrostatic pressure. I know that hydrostatic pressure equals (height)x(density)x(g). Am I right if I say that hydrostatic pressure in a bottle of water on ISS (state of weightlessness) will be zero ? Thank you for...

Using the above formula I get that the time goes 6.5∗10−86.5∗10−8 percent faster in ISS. Thus, this is approximately 2 seconds in a year. But the answer is much lower. Where am I making a mistake?

NASA says the ISS is 200 miles away. Planes fly at around 10 miles from the surface and we can't see them due limits to the angular resolution of the human eye. Given the inverse square law of light and the ISS being 20 times the distance to the plane, how is it possible to see the ISS?

I would like to know what will be the visibility from the portable telescope aboard the International Space Station. What could they potentially view, and what are (at least some of) the things they are known to have looked at? Presumably they use it *inside* the ISS and not outside, and are...

I saw a physics problem on Craig’s List (of all places) that piqued my interest. I’ll paraphrase it: An astronaut on the ISS placed a large magnetized sphere outside the station far enough where the station had no effect on the magnet then threw a large pail of iron filings at the sphere. He...

Nauka, a Russian multipurpose science module and one of the largest ISS modules, was docked to the ISS. During the checkout procedures after docking the module suddenly fired its thrusters, rotating the ISS quite rapidly (up to 0.5 degree/s). The Zvezda module and a docked Progress resupply ship...

Hello All The Hafele-Keating experiment in 1971 confirmed measurable time dilation effects on atomic clocks flown around the Earth on aircraft. Presumably clocks aboard the International Space Station suffer worse time dilation because of their greater speed in orbit. How often are corrections...

The Boeing Starliner just launched into a pre-sunrise cloudless sky. It was fun to see the black smoke trail change to white as it lifted into the sunlight (pic 1). It was not as spectacular as the post-sunset launch from California a few months ago. The trajectory became more horizontal...

What does a helium balloon do on the ISS . most say, its a 0 g environment, but is it really the same as intercosmos travel "0g"? I saw a video of helium ballons on the vomit comet, where during the "0 g phase" the helium balloons went to the floor, while all other things floated. I would...

I've seen much about jerk, and how it's generally nearly instantaneous, and for general acceleration, that's fine. However, if I lift at a constant acceleration upward slightly stronger than gravity is pulling me downward, the gravitation pull of the Earth will offset part of my force, so that...

Homework Statement I am faced to a problem of interpretation illustrated on figure below : I must precise that I talk about **mean anomaly**. Homework Equations for the 2 questions, I am asked to find : 1) at which anomaly is the ISS at the two lines epoch ? 2) at wchich anomaly is the...

The ISS suffered a leak apparently caused by a 1/8 inch hole left during manufacture and never repaired. On Quora, the claim has been made that such a hole with one atm of pressure difference would only cause 324 cu ft of air to rush out per hour. I don't think this is close to correct, but I am...

I JUST spotted the ISS with my powerful binoculars, How luck I am... :woot: I was looking at Sirius and just then a streak of non twinkling light passed through, when I ran to desktop to check ISS tracker i saw it was just over India... I feel very lucky to see the greatest project of mankind...

What is the practical feasibility of changing the International Space Station's orbital inclination to match the orbit of the Moon? Major future missions beyond the Earth-Moon system (ie: space colonization) will likely require in-orbit assembly of components from multiple launches. And...

Last time I looked at the stars for fun must have been when I was 6 or 7 or 8 years old - who knows. Somewhere I learned about the Big Dipper - whether from a parent or from passing through Grand Central Station - but not much more. Very recently I have realized that although I live in a...

I was thinking about two spheres of lead, 1 Kg and if I remember right would be about 3 cm radius. So inside the ISS in microgravity could the gravitational attraction of the two spheres allow them to orbit one another? I calculated an orbital time, if 2 cm apart of about one hour per orbit...

I use several web sites to search the visible passes of the ISS over a given location. Then I calculate the Sun elevation as seen from the ISS and I get surprisingly low elevations; for example, I get ISS magnitude= -3.8 and Sun elevation at the ISS= -19.9 deg. I suppose that the atmospheric...

I have a friend who I was trying to explain why we can see the ISS. Unfortunately though I don't have a good enough physics background to adequately answer his question, which was: "Why can I not see a plane once it reaches about 80 km away, yet I can see the ISS, at over 250 km away" This is...

Tomorrow Fri Jan 13 the second part of the mission to replace the batteries, the second recent spacewalk outside the International Space Station (ISS). Last week commander Shane Kimbrough and flight Engineer Peggy Whitson of NASA. This week commander Kimbrough and Thomas Pesqet of ESA (European...

When International Space Station is at rest, it revolves around it's axis once per orbital revolution (92.65 minutes). In other words, is tidally locked. Does the spinning around it's axis do create non-zero artificial gravity? Does it have non zero angular momentum?

Hi, I read about definition of microgravity. It is usually described as reduced g, but not zero g. How can one say then that an object is in microgravity? I was looking hours for a clear definition, like an object is in microgravity if there are just 10^-6g left (clearly wrong, because I read...

Homework Statement Consider an experiment on the International Space Station, which is illustrated below. A cylindrical capillary of length L= 10. [cm] and inner diameter of dc=500. [µm] (sealed at one end), is positioned to contact a droplet of water, D = 1.0 [cm], which is floating in the ISS...

Obviously, just about anywhere you go in the ISS, the walls are lined with electronics. Potentially a silly question, but why don't the astronauts need to be more careful when they handle water, considering that it could short circuit the electrical systems? Example:

Before I begin this thread I must confess to nearly complete ignorance of Quantum Physics, or for that matter most any technical science.(I'm somewhere between a consumer and a parasite). That being said I came across this JPL link and it caught my attention, seems to be some groundbreaking...

The B612 Foundation, http://en.wikipedia.org/wiki/B612_Foundation http://b612foundation.org/ is a nonprofit composed of astronauts, scientists and engineers dedicated to the cause of developing a technological early warning system to detect distant asteroids that might be future dangerous...

I was watching the following video, and I have a question about something they said that seemed kind of vague (I know I could have asked in the video comments section, but this forum tends to supply much better answers, so I hope it's OK that I am asking about a YouTube video here): If you...

I was watching the ISS live feed (from YouTube) and came across this strange look. https://gyazo.com/c5a09c7af0412c4c361fa0549b03a29d Does anyone know what would cause this in the live feed?

Experts - Why they don't increase altitude of ISS to overcome slight atmospheric drag it faces. Due to this, they need to make altitude corrections frequently to ISS. I want to know, why they can not put ISS in higher orbit where there is almost nil atmospheric drag (or may be altitude...

Suppose I am on ISS and Earth is exactly below (at the right angle to the ISS's line of path). Now if I throw one ball below towards Earth from window at exactly 90 degrees to the line of path of ISS and one ball upwards at right angle to the line of path of ISS. **Assume normal human strength...

My name is Vamsi and I am from India. I am currently pursuing Ms in ME at University of Houston-Houston-Texas-USA. I have taken a course called "space vehicle design" in which we need to form a team and do a project of our choice. My team project is "Designing a space capsule to carry...

ISS flyover about an hour ago: 800/5.6, 1/1000 s, ISO 1000. ISS was maximum magnitude -2.0, I tried to 'pre-calibrate' against Vega but still underexposed.

An astronaut on a revolving space station releases a wooden spoon out of the satellite, into empty space. Will the spoon fall toward Earth ? What will happen next ?

why is there no telescope like Hubble on the international space station/? as i know, the iss is only 150 km lower in orbit than the Hubble space telescope, and is at different inclination. Having people around is pretty convenient i think, so replacing parts and doing regular maintenance would...

I wondered, how much micrometeors, solar storms endanger the infrastructure and personnel of ISS? Does it require really thick outer walls, and quite regular maintenance?

I'm aware that it orbits West to East and covers almost every part of the land on Earth. But what is the reason behind it not passing over Arctic and Antarctic regions?

On the ISS, special relativity dictates the station's clocks run slower than clocks on Earth because of the high velocity, but general relativity dictates that the station's clocks run faster than clocks on Earth because of the lesser gravity. Which effect is predominant, and do the station's...

Greetings all ! I have this problem with SGP4 propagation, that I hope someone can help me out with. I acquired a TLE of the ISS from internet and used the C++ SGP4 propagator to compute future position and velocity vectors of the Station. I am unsure about some aspects of results though and...

Hey All, Would the International Space Station be visible to the naked eye if it was painted black? Thanks for any replies!

The International Space Station now has a set of High Def cameras hooked up to a live stream. High Definition Earth Viewing When it's on the dark side of the earth, it will often appear black. You can use this image to check it's location. Refresh the page to get the current location.

background information is that I have been working on code for a rocket launch to the ISS and I have gotten it close. The problem is when calculating the Force of drag, the problem occurs with it. As entering space, and for this "model" were going to say that temperature is 0 K in space or...

Why did the ISS cost just over 57 times as much as the LHC? What was it about the ISS that made it so expensive to build? $150billion is crazy! The LHC costs just $2.6billion

...curvatures in spacetime being created by Earth's gravity? My understanding is that its speed offsets the gravity being created by earth, that it's freely falling towards Earth but never hits it because its speed somehow causes it to keep missing. If that's the case, wouldn't that suggest...

If you had nothing particularly pressing to do, and the International Space Station was passing over at the right time to be easily visible, would you bother watching it? The International Space station (ISS) is easily visible, if the timing is right: it needs to be passing overhead within a...

I have been following this for the last few days, they launched the Falcon 9 rocket with the Dragon capsule on Tuesday, then Thursday had to perform a series of tests to make sure the Dragon spacecraft was working fine, now they are docking. They had to perform multiple tests on it to make...

How do occupants living on board the International Space Station (ISS) survive exposure to solar storms and especially coronal mass ejections?
