02:04 ZeroOne : Don't call it sq***ing.
02:04 CJSF : lol
02:04 loonyman : QUESTION Does the new MRO image throw any light on the
glinting object in the lander photos?
02:04 djellison : The drop test vid rules out squidding - it opened really
quickly I thought. MER's chute design had DREADFULL squidding early on
:O
02:04 ynyralmaen : Question: can they also use Mars Express as a backup
for the UHF comm?
02:04 marko-1522 : let's call it PZ-ing instead of squi**ing
02:05 CJSF : good one marko
02:05 ZeroOne : dje said a bad word. heh.
02:05 newmars : QUESTION: any problems at all with PHX or it is really
perfect?
02:05 soucerofmilkfortable4 : Speaking of Mars Express, was it able to
capture a descent image like MRO-HiRISE?
02:07 Maquis : QUESTION: Does that mean that MRO can't establish UHF connection
to MERs too?
02:08 surreyguy : thx, Emily!
02:08 CargoCult : (Emily's internet connection is relayed by MRO?)
02:08 djellison : Mars Express could do UHF with Phoenix if needed ( it
did during EDL )
02:08 vrruiz : CargoCult: lol
02:08 djellison : And the MER's just use Odyssey - not MRO
02:08 dragonsyoung : cargo bad boy
02:08 loonyman : Nars express will probably release an image in 6 months
or so, they only get out half a dozen images a year!!
02:09 ynyralmaen : Ta Doug
02:09 Maquis : CargoCult: that would be one hell of a 'bent pipe' ;)
02:09 marko-1522 : hydrazine again, poisoning Mars :-D
02:09 newmars : QUESTION: Will they use the RAC to make a closeup survey
of the ground?
02:09 joshcryer-1 : loonyman, yeah, they need to work on their data releases,
it goes to PDS but over a *long* wait time.
02:09 ZeroOne : don't say it
02:09 joshcryer-1 : loonyman, I'm *still* waiting for Venus Express data!!
02:09 joshcryer-1 : STILL!
02:09 joshcryer-1 : (oops, sorry for spamming the chat, thought I was somewhere
else)
02:09 newmars : QUESTION: Can the ground temperature be directly measured?
02:10 ZeroOne : two minute push broom isn't it
02:10 ustreamer-85388 : Question: Mic is off, as it can bog computer, but
is there any chance to turn it on at the end of the mission?
02:10 dexgod : They just said they might soon
02:10 dragonsyoung : there is a chance at the end of the mission
02:10 dexgod : in the latest post
02:10 joshcryer-1 : 85388, they said they can turn it on at end of mission,
but it may not work, since it was designed for descent.
02:11 ustreamer-94205 : THIS IS THE 4TH SUCCESFUL EDL FOR A MARS LANDING;IS
NASA NOW CONFIDENT THAT IT HAS OVERCOME THE PROBLEM OF PUTTING A LANDER ON THE
PLANET?
02:11 ahecht : 94205, there's still only a 50% success rate
02:11 newmars : nothing in the press kit
02:11 ynyralmaen : Isn't it the 6th for NASA?
02:11 Maquis : landing is always a gamble ;)
02:12 Maquis : ask russians, they know ;)
02:12 joshcryer-1 : ahecht, Mars landing with NASA has only failed once.
The Russians stacked that stat. :P
02:12 marko-1522 : Soyuz?
02:12 Maquis : more like russian mars missions
02:12 dragonsyoung : ty for that mic info
02:12 WolverineTX : Viking 1, Viking 2, Sojourner/Pathfinder, Spirit, Opportunity,
Phoenix
02:13 ahecht : Well, three if you include Deep Space 2
02:13 ugordan : QUESTION: Any initial thoughts from the teams on how much
excavation was done by the backshell/heatshield?
02:13 WolverineTX : So NASA's 6 for 7 ;)
02:13 newmars : QUESTION: have you still got your tattoo?
02:13 ahecht : 6 for 9
02:13 WolverineTX : erm, 9.
02:13 WolverineTX : Sorry, lol
02:13 joshcryer-1 : ahecht, what are the other two?
02:13 WolverineTX : Can't watch and type at the same time :D
02:13 ustreamer-76187 : ciao
02:13 ustreamer-66286 : QUESTION Since it the warmest part of the year
in the polar area is there a potential for dust storms at the landing site
02:13 dragonsyoung : Question: what is you thoughts on the rocks around
the landing sight some seem to like pumis
02:14 ustreamer-94205 : COS I BELIEVE SUCCESS OF PHOENIX WAS VERY IMPORTEANT
FOR MSL
02:14 loonyman : QUESTION was the downtime on Plan.org and here due to
over-subscription or hacker attack?
02:15 ustreamer-94205 : IT COULD HAVE DELAYED MSL IN CASE PHOENIX FAKLE
02:15 ustreamer-8421 : Just curious: If there was a manned mission
to Mars, and you were invited, but there was not guarantee of return to Earth,
would you go?
02:15 joshcryer-1 : Hah!
02:15 joshcryer-1 : Emily for the win!
02:15 ustreamer-94205 : FAILED
02:15 WolverineTX : ah I was right the first time :p
02:15 joshcryer-1 : Thank you Emily.
02:15 launchwatcher : QUESTION: Did they mention anything about how the
power panels are doing? day vs night?
02:15 Maquis : 6 for 7? ;)
02:15 ahecht : 6 of 9! Don't forget Deep Space 2 Microprobes!
02:15 joshcryer-1 : WolverineTX that's why I was asking ahecht to clarify.
02:15 ynyralmaen : It's probably fair to say that the Soviet Mars 3 was
a sucessful landing as it failed on the surface and started sending back
an image
02:15 ustreamer-93101 : Question: Is there any hope that the Phoenix will
be able to wake up after the Martian winter?
02:15 joshcryer-1 : ahecht, don't count!
02:16 NM : QUESTION: Since the local pressure is above the triple point
for water, could there be signs of liquid water pooling in the recent past?
02:16 ZeroOne : Phoenix has Lazarus mode and will phone home of it can.
02:16 ustreamer-94205 : WHEN THE GROUND FREEZES OVER WITH CHANGE OF SEASON,IS
THERE ANY IDEA HOW THICK THE ICE WILL GET AROUND PHOENIX?
02:17 dragonsyoung : up to a foot
02:17 ustreamer-94205 : WILL IT BURY PHOENIX?
02:17 nevets01 : your pretty
02:17 ZeroOne : cover 7-foot-tall Phoenix
02:18 newmars : QUESTION why is the lander deck so dust free?
02:18 dragonsyoung : lol
02:18 dragonsyoung : there is a dust sheild on the lander
02:19 newmars : thanks nevets01
02:19 ZeroOne : Give Phoenix some time to get dusty.
02:19 ustreamer-8421 : QUESTION: If there was a manned mission to Mars,
and you were invited, but there was not guarantee of return to Earth, would you
go?
02:20 newmars : there shold have been dust settle out from the landing
02:20 ustreamer-80808 : yes, but it was pushed in all directions by the
thrusters, i.e. away from the lander
02:20 ZeroOne : The force from descent engines was down and out.
02:20 ustreamer-80808 : with the time delay on array deployment, it is
pretty clean
02:20 newmars : 8421 - that's a but like travelling pn Britsh Airways
02:21 ynyralmaen : joshcryer: DS2 microprobes - apparently they were independent
of MPL and their loss was independent of MPL landing failure, so I reckon 6 of
9 is fair!
02:21 akuo : QUESTION: any news about the actual power output from the
solar panels?
02:21 ustreamer-93101 : QUESTION: Is there any hope that the Phoenix will
be able to wake up after the Martian winter?
02:21 djellison : I'm using BA in two weeks...from Terminal 5.
02:21 newmars : good luck!
02:21 djellison : The bags have as much chance of being imaged by Phoenix
as they do of arriving with me
02:21 ustreamer-79601 : me 2 terminal 5 in 2 weeks..fingers crossed
02:22 ustreamer-94205 : you'll get delays
02:22 BigBobUK : QUESTION - a friend was asking how come the Visions of
Mars DVD didn't fry during entry? Would it still be playable?
02:23 ZeroOne : Phoenix enclosed in heat shield and backshell
02:23 newmars : put one in your freezer and see what happens
02:23 Maquis : and why do You think Phenix didn't burn? ;)
02:24 loonyman : Question, How long are you there for, and are you made
welcome?
02:24 ahecht : the Phoenix DVD is not a standard plastic DVD with aluminum
film -- it is gold and glass
02:24 loonyman : sorry Dj , I meant QUESTION!!
02:24 kalaru : hello from Australia, the local press claim the intial data
went to the Canberra Deep Space Centre, 4hrs later Tidbinbilla took over, b4
it was transmitted to Pasadena. Is this correct?
02:24 joshcryer-1 : ynyralmaen, I just feel that they were too unlikely
to have survived since they didn't have chutes, being considered more a crapshot
than an actual attempt to land.
02:24 ustreamer-25979 : will phoenix be able to capture images of the martian
ice cap as it develops during the winter, or will it freeze before that?
02:24 dragonsyoung : lol
02:24 dexgod : type QUESTION before asking
02:25 dexgod : you make it easier for her
02:25 ustreamer-6229 : QUESTION - when will get get to see some panoramos
from Phoenix?
02:25 ustreamer-70093 : Did they ever find the Mars Polar Lander?
02:25 ugordan : hand-written? wow
02:25 ustreamer-6229 : *panoramas
02:26 ustreamer-79601 : MPL not found as far as I know
02:26 ugordan : no, MPL still remains lost
02:26 ugordan : you're welcome to help search, though :)
02:26 newmars : QUESTION: did you see MSL?
02:26 volcanopele : you can always stop by Sonnet if you come to Tucson
02:27 CargoCult : QUESTION: Is the effective 'mission control' now in Tucson?
02:27 loonyman : some of us are lookin for the MOL right this second ;-)
02:27 ustreamer-69448 : QUESTION: Has any decision been made on a launcher
for Cosmos II
02:27 loonyman : MPL
02:27 joshcryer : QUESTION: Emily, do you know if we will get new images
tonight despite the MRO problem?
02:27 ugordan : any sign of it yet, loonyman? :D
02:27 ustreamer-35232 : can the lander communicate directly to earth?
02:27 ynyralmaen : joshcryer: hmmm. I bet we'd be talking about 8/9 if
it was only MPL that has failed that year! I get your point, not sure I agree...
:|
02:28 Maquis : lander can't comm to earth
02:28 djellison : 35232 - No. UHF to the orbiters only.
02:28 dragonsyoung : yay australia my home
02:28 ustreamer-94205 : QUESTION:is the ice under the soil expected to
be rock hard or soft like snow?
02:28 Maquis : it doesn't have direct to earth antenna
02:28 loonyman : I thought I had found it friday night, but then realised Í was
drunk and had dirty glasses!!
02:28 surreyguy : Golly, so Phoenix was always relying on the orbiters
continuing to function...
02:29 ustreamer-93101 : QUESTION: In your mind, what is the best outcome
of data gathering by Phoenix? What's the best thing you can anticipate
to find there (besides life ;))?
02:29 ugordan : well, it does have 3 orbiters to choose from in principle
02:29 ustreamer-70093 : Why didn't they use a nuclear powered lander for
this?
02:29 ustreamer-45498 : url for those panoramas?
02:29 CargoCult : http://fawkes3.lpl.arizona.edu/images.php?gID=0&cID=8
02:29 ustreamer-80808 : nuclear's a pain, there's actually a limited about
of fuel available
02:30 Maquis : because RTG is heavy
02:30 Maquis : plus there isn't much fuel available
02:30 ugordan : not to mention political issues of RTGs
02:30 loonyman : Question. How much memory does it have, and what sort
of speed is the uplink?
02:30 newmars : :)
02:30 ugordan : *cough*environmentalists...
02:30 volcanopele : QUESTION: I just wanted to confirm, should we expect
new images from Phoenix during this evening's Odyssey pass? Or will it
be of the same terrain?
02:30 dexgod : I wonder what's the average speed in KB/s in the comm with
the orbiters
02:30 Maquis : uplink is max 128 kbit/s to ODy
02:30 djellison : MSL - Nuclear powered, laser wielding...and frickin huge.
02:30 dexgod : oh
02:30 joshcryer-1 : djellison, they're keeping the laser?
02:30 surreyguy : Hey, some of us are proud to be environmentalists
02:30 ustreamer-94205 : think more budget problem
02:30 ustreamer-8971 : what is she talking about?
02:31 djellison : Yup - Chemcam got put back on
02:31 ustreamer-8971 : anything significant?
02:31 ZeroOne : chem-cam is back
02:31 joshcryer-1 : djellison, that is great nwes if it got kept on. ChemCam
rocks.
02:31 ustreamer-8971 : or earth shaking
02:31 ustreamer-8971 : ?
02:31 akuo : yay for lazer guns
02:31 ustreamer-16383 : MER can do 256 kbps in some situations. Maybe Phoenix
can do the same.
02:31 joshcryer-1 : ZeroOne, that will make the mission 100x more effective,
wow.
02:31 ahecht : lol at Volna
02:31 ugordan : is the UHF datarate predetermined or adaptive?
02:31 djellison : predetermined
02:32 Maquis : adaptive
02:32 djellison : LOL
02:32 loonyman : lol
02:32 ugordan : lol make up your mind
02:32 ugordan : :D
02:32 ZeroOne : two msl instruments restored: http://www.planetary.org/programs/projects/space_advocacy/20071109.html
02:32 Maquis : pre?
02:32 Maquis : how?
02:32 ustreamer-79601 : lol
02:32 ustreamer-80808 : the Mars Telecom Orbiter (canceled) would have
been the first adaptive datarate platform at Mars
02:32 Maquis : hmm
02:32 akuo : thanks emily!
02:32 ZeroOne : bye thanks
02:32 ustreamer-45498 : thank you emily
02:33 surreyguy : Thank you!
02:33 WolverineTX : Thanks, Emily! :)
02:33 AshRS : thank you!
02:33 CargoCult : Thanks again!
02:33 CJSF : Thank you Emily
02:33 BigBobUK : Thanks Emily
02:33 ustreamer-49262 : thats better
02:33 ustreamer-79601 : thanks yet again
02:33 ustreamer-8421 : Thank you so much!
02:33 ZeroOne : same time so we have to choose
02:33 ustreamer-22596 : thanks Emily
02:33 joshcryer-1 : QUESTION: Before you go, do you know if we will get
new images tonight despite the MRO problem?
02:33 dragonsyoung : thank you emily
02:33 marko-1522 : Great questions, greater answers!
02:33 Maquis : They said on briefing that lander would max datarate from
32K to 128K... that was predetermined?
02:33 ustreamer-49262 : irish
02:33 ustreamer-53882 : thanks!!
02:33 ZeroOne : out
02:33 loonyman : Thanks from Sweden Emily.....
02:33 ustreamer-49262 : go figure
02:33 ustreamer-78758 : greetings from Spain
02:33 CJSF : w00t!
02:33 marko-1522 : our pleasure
02:33 quirkquark-1 : great info. thanks
02:33 ustreamer-73671 : Thanks again! Interesting and informative.
02:33 djellison : Yup - the 8k and then switch to 32k was pre-programmed
02:33 ustreamer-40449 : lol
02:33 ustreamer-94205 : thanks
02:33 Maquis : ah
02:33 CJSF : Thanks to moderators too
02:33 NM : Adios
02:33 ugordan : but wasn't EDL a special case?
02:34 joshcryer-1 : Thanks Emily. Caio.
02:34 ustreamer-45498 : thanks a lot
02:34 ynyralmaen : Thanks Emily.
02:34 djellison : And with MER - the pre-select good passes for 256k
02:34 CJSF : so very cool
02:34 launchwatcher : Your's are more interesting than bad astronmers.
Thanks!!
02:34 CJSF : 'night everyone
02:34 ugordan : you wouldn't want the lander to pick its own rates
02:34 Maquis : they said it in a way I thought it's adaptive :)
02:34 joshcryer-1 : djellison, did you say yes we will get new images?
02:34 surreyguy : 'night all!
02:34 msnewel : Thanks for all the in depth coverage Emily!
02:34 djellison : http://mgsw3.jpl.nasa.gov/seq/relay/srpr/06208-06222.S00.apgen.notes -
