Space Toilet Broken

Out in space, no one can hear you scream when the one toilet breaks. That's the status on the International Space Station right now. Solid waste is being taken care of just fine, but liquid waste currently is having problems that is temporarily being served by a "bypass" solution while the astronauts wait for new parts to arrive this weekend along with a shuttle.This all reminds me of the scene from Apollo 13 when the engineers need to fix the filter with available parts. Maybe someday this too will get the Hollywood treatment. Link

Would a container in space maintain its temperature?

It space where there are no particles in the air (metaphorically), would a container maintain its heat.  A vacuum doesn't conduct and in theory that would remove any chance of something losing its heat energy.  And if so would the earth lose all of its heat in the even't of the sun going away.  Or would it average out all of the temperatures, which would still be very cold and would leave the earth feeling about 0 degrees Celsius.  But in theory this would allow us to use some vast heating operation to raise the temperature of a planet and maintain it for us to live on.  I know that there are some things on earth that use the heat and convert its energy to other forms therefore heat is removed from within earth, but could those be eliminated?  This is all just food for thought for people and I kinda wondered what people would say.  Its all in all just fun to learn new things.

Space Heater Repair, is there a glue for broken heating element coil spacer that is inflammable? Answered

Usually a space heater consists of a fan mounted to a motor which is then mounted to a back plate. Connected to the back plate are reflective spacers that hold the heating element coils seperate from eachother so they don't spark. Recently, I figured I'd repair my space heater after it started sparking instead of going and buying a new one. I opened it up to find the spacer plate which has several arms for holding 1-5 coiled wires. One of the arms was broken and the coils touched which is why it was sparking. Seeing as this is a heater, i'm fairly certain I can't use a super glue or epoxy to fix the plate due to its flammable nature. The plates are not easily replaceable themselves as they've been spot welded into place. So the question, is there a type of glue which will hold up under high temperatures which is not flammable that will bond metal / plastic / ceramic. I'd estimate the heating element probably reaches no higher then 700 degrees. If you have any suggestions on how I would go about repairing this I'd love to hear your ideas. Thanks in advance.

Renewed Interest In Space, Lunar Explorations

Japan's space agency today launched its much-delayed lunar probe in the most ambitious mission to the moon since the US Apollo space flights.The Selenological and Engineering Explorer — or Selene — probe was launched on board an H-2A rocket from Tanegashima, the remote island location of the agency's space centre..............................Japan's mission comes at a time of renewed interest in the moon. China plans to send a probe, the Chang'e 1 to the moon, possibly this month. The Chang'e 1 orbiter will use stereo cameras and x-ray spectrometers to map three-dimensional images of the lunar surface and study its dust. China's official Xinhua news agency has reported that a manned probe could be launched within 15 years. Japan is also considering a manned mission by 2025.Meanwhile, Google has launched a $20m (£9.9m) competition to send a robotic mission to the moon. To claim the prize, a team of researchers will need to send a rover to the moon, make it roam for a minimum of 500 metres and send video, images and data back to Earth, all before December 31 2012.Full article hereRelated Articles:UK astronaut on moonIndia's unmanned probePlan for spaceport in SingaporeEverybody else want to go to space too..

Teens take pics from edge of space with a balloon

With a latex balloon, a camera, and some home-built electronics, four teens in Spain managed to get pictures from 20 miles up! The balloon was inflated with helium, the camera and electronics were attached and away it went up to 100,000 feet before it popped and returned to earth. The camera was still snapping away when the students picked it up 10km from the launch site.Team leader Gerard Marull, 18, said: "We were overwhelmed at our results, especially the photographs, to send our handmade craft to the edge of space is incredible."Completing their landmark experiment on February, the Meteotek team had to account for a wide variety of variables and rely on a lot of luck."The balloon we chose was inflated with helium to just over two metres and weighed just 1500 grams," said Gerard. "It was able to carry the sensor equipment and digital Nikon camera which weighed 1.5kg. Link

could we actually travel through space?

OK, earlier today i was watching sci fi science on-demand and it was the episode where he discussed hitting mars with several astroids and i thought of something: what if instead of using a normal rocket,why not use the only thing that we know of that is more powerful than a nuclear reaction? anti-matter! no, it is not a myth, CERN has been harvesting the stuff for decades, yet all they have is about 10 pounds or so. most likely less. in theory, we could make a two compartment chamber with an air lock between the two chambers, and in each chamber put a few particles of a natural substance and its anti- substance in the separate chambers with a remote module to open the airlock separating the chambers while we are several hundred miles away, with two possible,reasonable theories:1)the chamber skyrockets through the atmosphere and into the great unknown of the skies and stars 2) we create a new grand canyon in the middle of nowhere, harvest the profits of the tourist attraction and try again until we get it right, if we fail 2) then we have several hundred grand canyons!(whew!!!!!!!!!!)

I need help explaining the shape of this nebula Answered

Http://www.esa.int/spaceinimages/Images/2014/10/Butterfly_death_throes This image is the "Butterfly Nebula". I'm having trouble understanding it's shape. According to the accompanying blurb, the shape indicates a "bipolar nebular, where fast-moving gas can escape more easily from the poles of the dying star than around its equator. This creates a lobed structure reminiscent of an hourglass, or, as in this case, a giant butterfly." But... why? Why can the gases escape more easily from the poles?  Why is it harder to escape at the equator? Surely, if it was blasting from the poles, we would see a more linear shape, long "beams" of material shooting out of each end?  This image looks to me as if material blasted away from the equator, but parallel to the poles, almost as if the two halves of the star's surface were peeled apart, like turning half an orange skin inside out. Anybody got a borderline high-school/university level explanation for the shape?

Nerdman's Ships: Round 2

Hello! It's been awhile since I was here (was working on other things), but I've finally gotten around to making screenshots and renders, along with a bunch of new sketches (3D). I apologize for the amount Short List: (In order) - Assault Destroyer - Barracuda Class Frigate - Knife's Edge (now with new features) - Barracuda Class Frigate - Sky Razor (Sister ship of the above) - Falcon Class Heavy Cruiser - Hieroglyph Class Multi-role Fighter - Manta Class Bomber - Dolphin Class Artillery Frigate ::WIP:: - Mark XII - Light Torpeto Link to better images- http://s1206.photobucket.com/albums/bb441/nerdman234/ Minor side note: Thank you ibles for having an multi-uploader.  This is much easier than the other site I post on. :D - Nerdman  ------------------------------------------------ Expanded List:: ------------------------------------------------ - Assault Destroyer - Armed With 7 Medium Rail Guns - Designed for both direct assault and defense of large vessels against smaller ships (Frigates, bombers, etc.) - Barracuda Class Frigate - Knife's Edge (now with new features) - Designed for both exo-atmosphere and in-atmosphere operations - Armed with 4 light torpedo tubes, 3 triple AA turrets, and 2 solid mounted railguns in the nose - Barracuda Class Frigate - Sky Razor (Sister ship of the above) - Designed more as a heavy fighter than a support frigate, this can both keep up with standard fighters but even out maneuver them due to it's massive engines - Armed with 2 triple AA turrets, 6 light torpedo tubes, 2 solid mounted and 2 partially mobile railguns in the nose - Falcon Class Heavy Cruiser - Designed as fast attack ship, the falcon can reach incredible speeds while still being able to turn very sharply - The falcon is primarily armed with 512 packs of multi purpose launcher tubes, it can hold up to almost a thousand missiles or nearly 6,200 un-guided rockets. - Hieroglyph Class Multi-role Fighter - Carries two multipurpose modules (similar to the Heron) which hold quite literally anything that fits inside the power, weight, and computing restrictions. - Designed using spare Heron frames which were useless due to constant space combat. - Armed with a triple AA turret (rear), all other weapons/ offensive abilities come from the pods. - Manta Class Bomber - The Manta Class Bomber, created about the same time as the Hieroglyph, was made from XUAP hulls which were useless in space and were unused because of it. - Armed with 6 light torpedo (single use tubes), 3 triple AA turrets, and a minor ECM package, this bomber can hold it's own against even heavy fighters. - Dolphin Class Artillery Frigate ::WIP:: - The Dolphin Class of frigate was created when the fail "General Frigate" was unable to meet expectations. - Armed with 2 heavy plasma cannons capable of shots up to 400km away. - The Dolphin is also nimble enough to avoid long range missiles, but is unable to enter atmosphere and is unable to avoid fighters. - Mark XII - Light Torpeto - The Mark XII was created strictly for bombers, but soon showed extreme success in both heavier fighters, and light frigates. Being powerful for it's size, it was also reasonably light and nearly as maneuverable as some missiles.

Pressure, vacuums, and the on earth equivalent?

One atm is equivalent to about 14.7 psi.  Does that mean that if one was in a perfect vacuum a vessel sporting 1 atm would need only hold the pressure of 14.7 psi?  It seems to me that in space (not a perfect vacuum) a craft would only need to hold maybe 12 psi (of course when messing with human life I would definitely allow for 150 to 200% tolerance, but in the end 24 psi still isn't very much is it.  Is there more to it than this, or are all those quotes about how hard it is to deal with a vacuum and how things must be super strong a little over blown.  Going just 11 meters under water exposes you to a little over double air pressure at sea level.  Someone in just a diving suit has been to over 60 times atmosphere and the deepest submarine dive I could find was 1083 atm at around 11000 m.  It just seems to make holding out a vacuum a little overrated.

Food Creator and dispensor

This project is currently in the research stage. Having been reading the books 'Zero to Maker' by David Lang (OpenROV) and 'The Toaster Project' by Thomas Thwaites I have realised what I need is a project with a goal to take me out of the Arduino blinky light and solder kit zone, in to real making/hacking. Lang suggests an 'Unknown Project' which as I understand it is one that has been unexplored or under-explored, and he also suggests that using a popular forum to log, share and discus ideas would help the process along. So my idea, is an open hardware food creating machine, that will produce a large array of food, from a limited array of ingredients (approx 50) that can be made easily, and a ingredient markup language. 3d food printers in current development are either impractical or unappealing to me. They range from candy makers, ones that still need to be hand finished and cooked or the one publicised for receiving NASA funding recently used dead bugs. They seem all to focus on the gimmick, and not the food, and I like food. The other approach is the barbots, which seem to mostly perform flawlessly, but are unable to produce food. So my approach is to work through the process logically and break it down to sub projects. Design meals by hand using the limited ingredients for proof of concept, choose the ingredients to provide the widest possible range of nutrients and transpose the recipies to psudocode that can be easilly transformed in to a markup language later. Design a process for mixing and cooking ingredients. I envision a system of different food processors, steamers, boilers etc. and a range of extruding dies. Design a self cleaning system. Possibly ultrasonic or ionic. To that end, here is my preliminary list of ingredients. sugar, salt, oil, water, co2,Alcohol 37.5%,pectin,bicarb,nutritional yeast coffee,tea,mint,cocoa,garlic,oregano,chilli powder, paprika rice,soya,corn,wheat lemon extract,orange extract,tomato powder,dried apple,dried carrots,dried peas,potato powder. These ingredients can be used to make among other things, sausages, burgers, curry's, pasta, fries, soups, cereals, 'cider', cocktails, deserts, sodas, sauces, egg cheese and milk substitutes. So that's my plan. What do you guy think, and what ingredients would you add and why? And what would you call it? There are loads of things I left out as everything will change as I work through the process. Thanks for reading, Haydn

Any ideas for near space (weather) balloon telemetry? Answered

Hey guys, I'm considering a project like the recently popular near space balloon project. The only twist is that it could float for several days/weeks at a time. The major problem I have is that I need some way to reliably communicate with the system. The balloon would have to send climate data, gps data, and maybe photos. A video feed would be good too. I'd have to be able to control its descent and control its cameras. The issue I see is that many common systems are only good to about 40 miles which would still be way too short of a distance. Cellphones are obviously out of the question (way too unreliable up there). Satellite phones would break the bank. Power consumption is also a concern I have. I would consider getting an amateur radio license if you guys think it would help.  Note: I plan to use arduinos. JP Aerospace does some of the stuff I want to do with this potential project. The photo is their Away 46 mission.
