  1. Not really glue but people have been looking at gecko feet for robots stability recently. http://www.washingtonpost.com/news/speaking-of-science/wp/2014/08/12/new-research-investigates-the-physics-of-sticky-gecko-feet/
  2. I will look into it too. I've posted a couple messages on ESA's multiple facebook pages about this and will post any responses here. In my experience with GPR, antenna placement is really crucial for good measurements. I've had so much data distorted with the antenna being affected by topography. Some of my research has suffered due to poor surveying. But then again, they probably did plan for irregular topography so it is possible that the data may be corrected or unaffected by Philae's position.
  3. Yes, please have a go. I am interested in reading about that. I think, correct me if I am wrong, but the Rosetta sends the electromagnetic waves down and the Philae receives them then sends the data back to Rosetta. If this is the case, the antenna is on Rosetta and the receiver on Philae then perhaps the position of Philae wouldn't be too big of a problem? I'm really not sure. I have experience with GPR here on Earth but the CONSERT is a whole different instrument. Quite an amazing piece of technology.
  4. I apologize for back seat moderating. I just felt that this thread was going to be shortly derailed. It sounded like trolling. I didn't say he was wrong or they were right. I meant "smart" as in to recognize when someone might be trolling. I'm not trying to oppress opinions here (I was asking questions earlier about CONSERT data if you think I have nothing better to do). I just see an impass here and maybe I hoped that it could be settled in private message or they could agree to disagree.
  5. Well, I found this excellent paper about the CONSERT: ftp://ftp.eorc.jaxa.jp/cdroms/EORC-061/data/f_papers/ceos006.pdf I can't understand half of it but it might be enlightening to some of you.
  6. Some questions maybe some of you could answer to me about CONSERT: 1. The frequency of the transmitter they used is 90MHz. My estimation is that this has a penetrating depth of maybe 20-30 meters depending on the permittivity of the comet material. Does that sound right? 2. Would the lander being in a strange position affect the data? Could it be corrected? 3. If they didn't know the material making up the comet...then how did they know what settings to use for the CONSERT? In my experience, not surveying with an optimal dielectric setting can give inaccurate results.
  7. ".@Philae2014 now idling. Nothing happening on board. Power low. Loss of communication visibility expected at about 02:00 CET #cometlanding" Yup! Excellent! I look forward to the results whenever they publish. I'm glad to see penetrating radar being used in this mission. Another response to "what can on earth can you possibly learn by shooting electromagnetic waves into the ground?" that I often hear.
  8. Isn't a convex surface important when entry into an atmosphere occurs? The bell of an engine (or whatever it is called) is concave and almost surely could have strange aerodynamic consequences.
  9. Dusty? Tweet is just 19 minutes old Cool. Just wanted to know what the news was...this was just the first tweet I've seen about anything CONSERT related since the landing. Oh, there is this one too. They misspelled CONSERT xP ESA Operations â€Â@esaoperations 36m36 minutes ago Download link remains nominal despite v. low power. Waiting to receive #CONCERT data #cometlanding
  10. Does anyone know if they have used CONSERT yet? I really want to see some subsurface data. Or will it not be possible with the low battery?
  11. Same here. I'm in LA but can't make the premiere. Thursday at 8 for me...or maybe the midnight showing in Southbay.
  12. Well, I just had to speak for myself. I imagine you may understand this more than myself. I study geophysics and other irrelevant fields. Maybe you are capable of seeing the potential accuracy here when I might not. I really look forward to the papers as well. I imagine this will be a very discussed topic soon. Maybe it will inspire other big budget sci-fictions to participate in simulations like this. Can't wait for the movie either! Interstellar Nov 7th...Philae landing on the 12th. It looks like November is going to be one heck of a month!
  13. Sorry, I'm still skeptical. Especially when this article was published 1 week before the movie comes out. How do you know its accurate other than these short articles. I must be missing important information other than this guy saying "trust me".
  14. I'll wait until he publishes the two papers until I believe that this is accurate.
  15. That is an amazing opportunity! What kind of research at JPL? Do you work there or is it some sort of internship program?
  16. Humans make up corporations but I see where you are going with that. Love your idea on the patent, very clever!
  17. Slavery is a term used for human beings and human beings only. It would not qualify as slavery.
  18. If you can read Italian then it explains it a little more here: http://www.aliveuniverseimages.com/speciale-missioni/missioni-nel-sistema-solare/rosetta/930-esa-rosetta-i-primi-dati-di-alice,-cosima,-osiris-e-virtis But I posted an English response from these guys on the first page too. It might represent real colors but it is a simulated, thus a guess.
  19. That is not an "actual color" photo but simulated. Artist said this about this photo: "Hi all, no raw data. No OSIRIS image has been released with different filters so can get an RGB image as result. We started with a single image flic.kr/p/p6kuZs working on the information that we all know (low albedo, dusty surface, and so on), obtaining three virtual layer. Processing, as long as even our eyes were pleased and believed what they was looking at. In a way, we pushed to limit a technique that we use for a long time to make color native b/w shots to increase the visual perception." Source: https://www.flickr.com/photos/lunexit/14999812157/
  20. I've been trying to get a tour at SpaceX but apparently you need to know someone who works there! Really would like to see their work up close!
  21. I was wondering if they were any people here that are studying or have studied geophysics (applied too)? I'm an undergraduate at the moment and I'm using a ground-penetrating radar to conduct some field tests. I've been studying countless surveys and technical books to educate myself. Another instrument I'm using is a magnetometer but I'm less familiar with that instrument. I wanted to know if some of you have experience with these instruments. How have you applied them to your research, work, or education? If you don't have any experience but knowledge on the subject then I would be interested in what you think about studies using these instruments. I'm adept with both the tools (conducted field research in both hemispheres!) but rarely meet someone to discuss them with. Just reaching out! Instruments I'm using: GSSI 400 MHz and 200 MHz antenna and an Overhauser magnetometer. The research was mostly archaeological but naturally included geology as well.
  22. Wasn't SpaceX the only company out of the 4 for that recent contract that would use their own rockets and capsules?
