  • Leah Villalon, Geoff Hilton, Kirk Kittell have joined the conference.
  • Geoff Hilton: no clue Lavina
  • Leah Villalon: howdy
  • Lavina Parwani: heya
  • Geoff Hilton: ahoy!
  • Leah Villalon: who's in the house
  • Lavina Parwani: Sorry
  • Lavina Parwani: Leah, this is Geoff
  • Lavina Parwani: and Kirk
  • Tom Nordheim has joined the conference.
  • Lavina Parwani: And Tom
  • Geoff Hilton: heheh
  • Lavina Parwani: Everyone, this is Leah, my vicepresident for PhilSEDS
  • Tom Nordheim: hi
  • Geoff Hilton: Hi Leah
  • Kirk Kittell: hi Leah
  • Leah Villalon: hi everyone
  • Leah Villalon: how is everyone?
  • Geoff Hilton: Kirk
  • Geoff Hilton: I'm good, Leah!
  • Lavina Parwani: I'm pretty nifty myself
  • Lavina Parwani: Is this everyone for today's meeting?
  • Geoff Hilton: hehe
  • Kirk Kittell: but otherwise good
  • Geoff Hilton: I think it may be
  • Lavina Parwani: damn
  • Geoff Hilton: yup
  • Kirk Kittell: we may get Anbarasan or Amrut late
  • Geoff Hilton: Amrut won't be coming
  • Kirk Kittell: ok
  • Geoff Hilton: he's going to another city because of a radio talk show
  • Lavina Parwani: oh, fun
  • Lavina Parwani: In which case, maybe we should get started?
  • Kirk Kittell: yep
  • Kirk Kittell: Mission Concept Review
  • Kirk Kittell: is the main idea today
  • Kirk Kittell: wait a minute
  • Kirk Kittell: Mission Feasibility Study
  • Kirk Kittell: that is the link I wanted
  • Lavina Parwani: ah
  • Lavina Parwani: ok
  • Nikko Torcita has joined the conference.
  • Kirk Kittell: we
  • Nikko Torcita: hi
  • Tom Nordheim: dz_lemon?
  • Nikko Torcita: ?
  • Lavina Parwani: sorry, guys, this is Nikko
  • Kirk Kittell: we'll put our research in that document, suggest a few mission concepts, and explain how we think we can achieve the mission
  • Geoff Hilton: from last week?
  • Kirk Kittell: hey Nikko
  • Geoff Hilton: Hi Nikko
  • Nikko Torcita: yo?
  • Lavina Parwani: Kirk, can you explain the last bit?
  • Lavina Parwani: "how we think we can achieve the mission"?
  • Kirk Kittell: sure
  • Geoff Hilton: 2 hamsters in a wheel inside the cube...
  • Kirk Kittell: basically -- proving that we can perform the mission
  • Geoff Hilton: Yay us!
  • Kirk Kittell: in the industry, it would prove the mission is worth doing
  • Lavina Parwani: Ah
  • Lavina Parwani: I see
  • Kirk Kittell: we already think that, of course
  • Lavina Parwani: hehe, yep
  • Kirk Kittell: but this would prove that we can do it
  • Geoff Hilton: the fact that we can pull it off means it's worth doing?
  • Geoff Hilton: That's my kind of industry!
  • Lavina Parwani: but the trick is to make everyone else think that?
  • Kirk Kittell: yep
  • Kirk Kittell: so we can get others to join the team as participants or sponsors
  • Kirk Kittell: it is not too complicated, so don't worry
  • Lavina Parwani: Alright
  • Leah Villalon: ok
  • Kirk Kittell: Mission Feasibility Study
  • Geoff Hilton: Oh! I have a question which I believe we've covered before, but my memory is fuzzy
  • Kirk Kittell: for Nikko -- that is the link
  • Kirk Kittell: go for it
  • Geoff Hilton: I have (another) friend who really would like to join us
  • Lavina Parwani: When you say "Concepts" (I'm referring to the MFS link) what exactly do you mean?
  • Geoff Hilton: though he's as much a student as I am (we met at the same place), technically, he's already pretty started in his career (not space-related), he's a Project Manager I believe, where he works
  • Kirk Kittell: different ideas for subsystems
  • Kirk Kittell: summarizes the research we did
  • Kirk Kittell: and how we think it could be useful to our system
  • Geoff Hilton: kirk?
  • Lavina Parwani: So taking the Communications System as an example, I'll evaluate the different options available to us such as half wave dipole and quarter wave monopole antennas?
  • Lavina Parwani: and give my opinion on which is better?
  • Kirk Kittell: yeah
  • Kirk Kittell: that's it exactly
  • Kirk Kittell: yeah Geoff?
  • Geoff Hilton: my question lacked a question mark...but that was it, up there
  • Geoff Hilton: essentially, "can he join us, even though he's 30 and done his studying?"
  • Kirk Kittell: sure
  • Geoff Hilton: oh, ok
  • Kirk Kittell: that's fine -- send him the link to the email list
  • Geoff Hilton: will do!
  • Geoff Hilton: he's not on right now, probably sleeping
  • Geoff Hilton: we partied until 4am
  • Kirk Kittell: the wiki page is available for everyone to edit
  • Kirk Kittell: except Lavina.... which will be fixed shortly I hope
  • Geoff Hilton: hehe
  • Lavina Parwani: *crosses fingers*
  • Tom Nordheim: did you get the file I sent you Kirk?
  • Geoff Hilton: Lavina's question brought up a few of mine though, which will come back to me, hopefully
  • Tom Nordheim: I got stuck in an airport yesterday, so that is kind of of what I could manage when I was there
  • Kirk Kittell: no worries, looks fine
  • Kirk Kittell: I got the file
  • Geoff Hilton: for the Command & Data Handling subsystem, I'm responsible for the Onboard Computer System specs as well?
  • Kirk Kittell: yeah
  • Geoff Hilton: okay, I've already got some samples in my research page
  • Kirk Kittell: regarding the wiki page -- feel free to add information and then fix the grammar, etc., later
  • Lavina Parwani: Yep
  • Geoff Hilton: I'm thinking of an "anything but windows-ce" approach, I noticed one cubesat project used two PDAs joined together
  • Kirk Kittell: a short paragraph about each technology you studied will be good
  • Kirk Kittell: in fact, you could probably group similar technologies in the same paragraph
  • Lavina Parwani: do we have sample MFS documents?
  • Geoff Hilton: the "anything but windows" thing is just my personal moral stand, really
  • Tom Nordheim: I have some thought when it comes to onboard computers etc also, and it makes sense that we work on that together
  • Kirk Kittell: I found one or two example documents at work
  • Kirk Kittell: I'll search again tomorrow
  • Geoff Hilton: yeah tom? and of course, absolutely!
  • Kirk Kittell: (dialup is slow.......)
  • Geoff Hilton: *throws bandwidth kirk's way*
  • Nikko Torcita has left the conference.
  • Geoff Hilton: hmm
  • Kirk Kittell: but don't worry too much about existing docs on this one
  • Kirk Kittell: for the PDR and CDR it will be more helpful
  • Geoff Hilton: Oh!!!
  • Geoff Hilton: I remember my other Q now, looking at my research
  • Geoff Hilton: will we have thrusters onboard the satellite?
  • Kirk Kittell: maybe
  • Kirk Kittell: it depends
  • Geoff Hilton: I know Mike's latest e-mail suggests it could be a possible approach
  • Kirk Kittell: since we are a small group today, this is the plan for the week, then we can call the meeting short
  • Geoff Hilton: per his explanations, it would be the single best way to stay lined up perfectly with the sun, for continuous solar power, without requiring a battery on board
  • Kirk Kittell: if we need that much power, it will be a good idea
  • Lavina Parwani: Kirk, plan for the week = putting up short paragraphs about technology we studied?
  • Tom Nordheim: but it is also far more complicated than having a battery
  • Kirk Kittell: that's close, Lavina
  • Geoff Hilton: Yeah! ...but how "little" power does a thruster expend?
  • Lavina Parwani: hehe
  • Tom Nordheim: it needs fuel
  • Geoff Hilton: non-renewable, I imagine?
  • Tom Nordheim: an ion thruster needs a very high voltage
  • Lavina Parwani: I think that before we decide that we should calculate how much power each subsystem is going to need
  • Tom Nordheim: yeah
  • Kirk Kittell: it is a possible idea tho -- I know that ION-1 had small arc thrusters
  • Kirk Kittell: include it as an idea
  • Kirk Kittell: Mission Feasibility Study
  • Geoff Hilton: would there be a way of moving the satellite without requiring thrusters?
  • Kirk Kittell: add your research (in a coherent form) there
  • Tom Nordheim: reaction wheels
  • Geoff Hilton: what about that gravity boom idea?
  • Kirk Kittell: in the subsystems concepts
  • Tom Nordheim: yeah gravity boom
  • Tom Nordheim: also magnetic coils
  • Tom Nordheim: but they usually require power
  • Geoff Hilton: Ideally, I wouldn't want there to be a Plan E - Decommissioning
  • Geoff Hilton: reaction wheels?
  • Kirk Kittell: when you add info, send an email to the list
  • Kirk Kittell: so that we can have a look
  • Tom Nordheim: but these are more adc type things, not for propulsion
  • Tom Nordheim: but whatever we decide, adcs is probably going to be a must anyway
  • Geoff Hilton: oh! okay..well, my research is up on the wiki I'll e-mail about it afterwards
  • Tom Nordheim: we need to have the satellite stabilized in at least one axis, probably two
  • Geoff Hilton: yeah
  • Tom Nordheim: both for communications, power and the observational part
  • Lavina Parwani: yes
  • Kirk Kittell: don't forget to add it to the document Geoff
  • Geoff Hilton: eh kirk?
  • Kirk Kittell: your research -- add it to Mission Feasibility Study
  • Geoff Hilton: oh!
  • Geoff Hilton: Command and Data Handling it was currently there <---
  • Kirk Kittell: that is a good place for it
  • Tom Nordheim: I'll add it to the blog as well...
  • Geoff Hilton: yup
  • Kirk Kittell: but we also need to include info about command and data handling in our report
  • Kirk Kittell: that's what I meant
  • Geoff Hilton: oh okay, yeah
  • Kirk Kittell: yeah yeah, I'm confusing
  • Kirk Kittell: also, you should all add to two other sections: cost and schedule
  • Lavina Parwani: that's the other thing
  • Lavina Parwani: Costs?
  • Tom Nordheim: I'm a bit unclear about that part actually
  • Kirk Kittell: as you research, note (generally) how long it took to buy and develop these things
  • Lavina Parwani: in what terms should we add that?
  • Kirk Kittell: ok
  • Kirk Kittell: haha
  • Kirk Kittell: oh no
  • Geoff Hilton: in my report, I also mention how the CDH subsystem will work I imagine, as in how others implemented theirs and how I envision ours?
  • Kirk Kittell: $C or pounds or ...
  • Lavina Parwani: pesos
  • Tom Nordheim: are we actually getting any funding for this, or do we have to get some companies to sponsor us
  • Lavina Parwani: or rupees
  • Kirk Kittell: we will look for companies to sponsor
  • Geoff Hilton: in my case...taking all the output from every other subsystem and doing something with that info? (thinking out loud, correct me if you need to)
  • Tom Nordheim: ok
  • Kirk Kittell: and in some cases, it may be our universities that help with some of the costs
  • Tom Nordheim: I wouldn't view that as very likely in my case at least
  • Kirk Kittell: Geoff -- you'll briefly describe how the other technologies work and how they can work for us
  • Kirk Kittell: regarding the cost --
  • Geoff Hilton: okay
  • Kirk Kittell: very general
  • Kirk Kittell: in fact, you may just be able to find the entire cost of the other cubesat missions
  • Lavina Parwani: yeah
  • Kirk Kittell: it is just a way of proving that building a cubesat is feasible
  • Tom Nordheim: ok
  • Lavina Parwani: alright
  • Kirk Kittell: not just technology, but cost
  • Tom Nordheim: in the other cubesat I was on, we decided on using only off the shelf components
  • Kirk Kittell: and for us, we'll need to prove how we will work together across continents
  • Kirk Kittell: that may be best for us as well Tom
  • Tom Nordheim: *on the other
  • Geoff Hilton: so finding out how much the parts used in other missions cost, how much what we suggest, might cost. ..?
  • Kirk Kittell: I think what we do is this
  • Geoff Hilton: off the shelf components as opposed to home-brewed?
  • Kirk Kittell: we mention what other systems cost, then suggest a cost for our system based on that
  • Geoff Hilton: sounds good
  • Tom Nordheim: no as opposed to space grade or military grade etc
  • Lavina Parwani: yep
  • Lavina Parwani: as for how we're going to work together across continents, where on the MFS do we include our suggestions?
  • Kirk Kittell: hmmmm
  • Kirk Kittell: maybe Staff Plan
  • Lavina Parwani: Alright
  • Kirk Kittell: however -- you can add sections
  • Lavina Parwani: *nods*
  • Kirk Kittell: that was just a quick outline
  • Geoff Hilton: space grade -- stuff that costs millions which is specifically tailored for space in every respect? heh
  • Kirk Kittell: you can change everything!
  • Tom Nordheim: not that much
  • Tom Nordheim: but it is expensive
  • Geoff Hilton: yeah
  • Geoff Hilton: I imagine more on man-power costs than actual materials
  • Kirk Kittell: that is all I have for the mtg, but you can continue to discuss ideas just as you are now
  • Kirk Kittell: please go to Mission Feasibility Study and add your ideas today
  • Kirk Kittell: unless you are Lavina
  • Tom Nordheim: and some of the components are actually just the commercial ones which have been tested and certified for space
  • Lavina Parwani: I'll post the transcript and notes in the morning
  • Lavina Parwani: hehe
  • Geoff Hilton: oh I see
  • Tom Nordheim: sorry for being slow on that last week btw
  • Lavina Parwani: er, actually, I'll have the transcript ready to post
  • Kirk Kittell: no worries
  • Tom Nordheim: I got distracted by some assignments
  • Kirk Kittell: you can post it to the email list and someone will take care of you
  • Kirk Kittell: no problem, that's how school is Tom
  • Geoff Hilton: ditto tom, I need to invite time!
  • Lavina Parwani: alrighty
  • Geoff Hilton: invent, too, inviting seems terminal
  • Kirk Kittell: but seriously though -- add some idea today
  • Geoff Hilton: Oh!
  • Kirk Kittell: it does not have to be a perfectly finished idea
  • Tom Nordheim: yeah I will
  • Kirk Kittell: we can fix it later
  • Geoff Hilton: where are we on that algae thing?
  • Geoff Hilton: I never quite understood *why algae* ?!?
  • Kirk Kittell: algae?
  • Lavina Parwani: I might have to do it tomorrow or Tuesday--I need to get to bed soon
  • Kirk Kittell: ahhh... yeah
  • Kirk Kittell: that's ok Lavina
  • Geoff Hilton: I mean...we can scuba and pick it up ourselves, then put it under a microscope, say
  • Lavina Parwani: hey Martin
  • Lavina Parwani: er
  • Lavina Parwani: sorry
  • Lavina Parwani: haha
  • Tom Nordheim: I was just trying to think up a mission that's different from what the other cubes have been doing
  • Kirk Kittell: ok I see
  • Lavina Parwani: well, Geoff, the satellite will sense global disturbances
  • Geoff Hilton: oh okay, it certainly is
  • Tom Nordheim: algea growth can be linked to global warming for example
  • Tom Nordheim: it's one of the things they look at with envisat I believe
  • Lavina Parwani: Tom, you said you had another idea to, I believe
  • Geoff Hilton: SEDSat-2: Codename Obi Wan Kenobi
  • Lavina Parwani: haha
  • Tom Nordheim: yeah it was something a friend of mine is working on
  • Geoff Hilton: ooh, proving global warming would be good
  • Kirk Kittell: great Tom -- that reminds me
  • Tom Nordheim: pinpointing radars using relativistic doppler measurements
  • Kirk Kittell: include citations for your ideas
  • Kirk Kittell: if you find your info somewhere, include the link to a web site or book or whatever
  • Tom Nordheim: ok
  • Kirk Kittell: so it is a valid tech report
  • Geoff Hilton: maybe it'd finally put a cork in Bush's "global warming is a fallacy!"
  • Tom Nordheim: have you looked at the pdf I sent you?
  • Kirk Kittell: hmmm -- I don't think I received that Tom
  • Kirk Kittell: I just got the meeting notes, thought that was the file you sent
  • Tom Nordheim: ah wrong file perhaps
  • Tom Nordheim: ?
  • Kirk Kittell: let me look again
  • Tom Nordheim: I sent you a file with some more info on cameras etc
  • Kirk Kittell: can you send it again?
  • Tom Nordheim: just a short summary on what we have discussed with regards to the payload
  • Tom Nordheim: it should be the same file
  • Geoff Hilton: Oh! What about my concave surface acting-as-a-dish thing, how would that be incorporated into the report? I really like that idea!!
  • Lavina Parwani: I'll take that into account, Geoff
  • Kirk Kittell: not sure -- try to add it where you think it is best
  • Lavina Parwani: I mean to say, when I do my research
  • Kirk Kittell: someone can always move it to an appropriate section
  • Lavina Parwani: yep
  • Geoff Hilton: yeah, cause I don't think it would add to cost...would it?
  • Lavina Parwani: don't think so
  • Kirk Kittell: ok, everyone that isn't in the Philippines, add info to the report today
  • Geoff Hilton: since it would be physically part of the cubesat, as opposed to a protruding gadget or something
  • Lavina Parwani: hehe, thanks Kirk
  • Geoff Hilton: I think that would be me and tom
  • Geoff Hilton: lol
  • Lavina Parwani: hehe
  • Lavina Parwani: yeah
  • Kirk Kittell: and post something to the blog as well, following Tom's lead
  • Geoff Hilton: hehe, I really do need to do that
  • Lavina Parwani: And if you can get a message to Michael, Geoff, that might be good
  • Geoff Hilton: yupyup
  • Geoff Hilton: he's coming over later today actually
  • Geoff Hilton: we're gonna watch a movie
  • Lavina Parwani: cool
  • Kirk Kittell: excellent
  • Geoff Hilton: hehe
  • Kirk Kittell: ok -- all of the work this week is out-of-meeting work
  • Lavina Parwani: yep
  • Kirk Kittell: but if you want to discuss something, say it over the email list
  • Kirk Kittell: don't be shy
  • Geoff Hilton: okay!
  • Kirk Kittell: and check it before we are finished
  • Kirk Kittell: ok, that's all from me -- Lavina, you're saving the transcript and notes?
  • Lavina Parwani: Yep
