Absolutely awesome stuff, right by the book!

Did I hear correctly they're saying a quarter of a degree tilt? biggrin.gif

Posted by: elakdawalla May 26 2008, 12:00 AM

yes, 1/4 degree

Posted by: nprev May 26 2008, 12:01 AM

Gonna go ahead and call that "flat", then..... smile.gif

Phew!!!!!!!!!!!!!!!!!!!!!!!!!!!

Never doubted it for a second! rolleyes.gif

Posted by: David S. May 26 2008, 12:01 AM

That was simply amazing, my first live landing on another planet biggrin.gif biggrin.gif

Those last seconds were scary, it went so fast i thought it was going too fast ! That was beautiful cool.gif

Edit : no peanuts here, but i'm eating a Mars bar to celebrate this ! tongue.gif

Posted by: Roby72 May 26 2008, 12:02 AM

I suspect the last 100m down were a little longer than in the EDL simulation, isn it ?

This implies a (probably) very flat landing site. Maybe similar to Doug's rendering?

Perfectly aligned East-West as well! Perfect!!!

Bed time for me, don't look at the pics till I get back in the morning! smile.gif

"Solar arrays open" is listed as occurring at 00:06:33 ERT (UTC). Does anyone remember when confirmation that this worked is due?

Posted by: SpaceListener May 26 2008, 12:09 AM

Completely flat only landing site but still don't know how are they arounds!!!

Wait for few minutes for a possible transmission of pictures.

The solar panels will deploy a little after the touchdown. This pause allows the dust kicked up during the landing to settle and not collect on the arrays.

Posted by: pioneer May 26 2008, 12:10 AM

It landed at a 1/4 degree tilt

Posted by: climber May 26 2008, 12:12 AM

Peter is talking about extended mission! Mood is high, very high.
What a thing it was to share this with you all.

Edited : a big thanks to administrators an a thought for Emily having her server down. I hope you enjoyed the landing anyway

My guess would be during the Mars Odyssey relay that begins about 01:43UTC....

I believe it and I am in tears.... happens everytime...

WOW... those last few minutes went like seconds!!!!! to me... could hardly keep up on my checklist....

Can't wait for those first thumbnail pics.... remember MER??? This should be very flat (so few rocks, Doug????? laugh.gif ) but just to see those solar arrays fanned out will be beautiful.....

now for that shot of Jack... CHEERS!!!!!

I second climber's comments - kudos to the UMSF team for letting us share this! The site worked smoothly right through landing. And thanks to dmuller for the great simulation.

Oh yeah, and, according to my formula, Mars currently occupies 180 degrees from the viewpoint of Phoenix! biggrin.gif

Posted by: Stu May 26 2008, 12:26 AM

Fantastic evening everyone, just fantastic... and what a BRILLIANT way of experiencing it with everyone here!

No WAY I'm going to bed before seeing those first pictures... laugh.gif

The first powered landing on Mars for 32 years. That's a lot of time.

Posted by: SFJCody May 26 2008, 12:28 AM

And next time... a completely new system for powered descent... SKYCRANE ph34r.gif

except for the RADs on on pathfinder and MER wink.gif

Yes - I can attest to the 32 year time span, having been at JPL for the Viking 2 landing...

Posted by: climber May 26 2008, 12:30 AM

This give good mood for skycrane.
1- they'll do a lot of studies since this will be THE futur landing system
2- Only the last meters will change as compared to full powered descent

Posted by: Steve G May 26 2008, 12:32 AM

I had to switched from Discovery Channel to my computer to watch NASA TV to rid myself of their commentary! A lot more exciting on NASA TV!

I'm still quite emotional. Landing on an alien world does that to the soul.

Posted by: akuo May 26 2008, 12:36 AM

Woohoo! Wonderful! Can't believe how happy these moments are.

Has somebody already put the last few minutes on youtube so we can relive those wonderful moments of telemetry-bliss!

Posted by: Gonzz May 26 2008, 12:37 AM

I'm working late tonight at the moment, deadline next morning, so it's perfect for waiting for those first few pics smile.gif
The first views from an alien landscape, so incredibly far and yet now so close

Very emotional landing, specially doing it live here with all of you.

Many Congrats for the Pheonix team, thanks so much for sharing your vision with all of us.

Spirit and Oppy have company!

Maybe during the checkoff in five minutes power production will indicate the state of the panels.
Don't know if it will be clearly stated at that time, but surely the first pictures to come down in a little over an hour will show the panels in all their glory!

Posted by: Leither May 26 2008, 12:37 AM

Emily has taken her laptop into the press briefing - see her Ustream. Sounding good.

I think my two quickest streams of information were National Geographic and hardcover books.

But by Pioneer Venus I'd started to make use of the small-town newspaper.

And after Voyager at Jupiter, Science News.

Galileo's arrival was when I joined the world of "real time".

Seems like we're at the end of that evolution now. We could only cut seconds off.

My mistake. An off-hand comment by Doug led me to think that Rob was part of the Phoenix EDL team, but maybe he was just part of a review panel. But Rob always has something interesting to say.

Posted by: climber May 26 2008, 12:53 AM

Everything looks nominal. Only parachutte deployed 7 second late which support we'll have landed long.

Posted by: mars loon May 26 2008, 01:35 AM

Peter Smith is on Live now on NASA TV

he is talking surface operations "They are ready to go. We will analyze from surface down to ice layer""

First few hours are all preprogrammed. We willl take pictures of solar arrays first. they lander foot . then lander horizon"

New Data/Images expected in a few minutes

Posted by: Norm Hartnett May 26 2008, 01:37 AM

Looks like they are going to cover surface ops from EDL/JPL. At least for the first pictures which is all PAO will cover.

Hopefully UA will do as good as or better job than the MER folks have done.

I was watching live on the science channel when at T-5 minutes to landing my grandma was like "ok time for cake! *clicks TV off*" I was like "NOOOOOOOOOOOOOOO!!!!". I don't think I've ever ran for the TV remote so fast in my life! rolleyes.gif

I'm really happy right now...

Large rock, I suppose. This one should be around several feet tall.

Posted by: kwan3217 May 26 2008, 02:07 AM

lg_320.jpg? Looks to me like its a "hole" in the lander shadow, like there is a triangluar hole in the spacecraft over the leg or something like that.

Posted by: Stu May 26 2008, 02:07 AM

Oh wow, look at that... lots of little pebbles to cast shadows in the slanting sunlight.... an intriguing "something" on the horizon... features on the ground... Flat? Maybe. Dull? Absolutely not!

I think that's just a little spot that's not in shadow. Take a look at the large version:

It looks just like the sunlit part on the left.

Posted by: tuvas May 26 2008, 02:08 AM

If they could get these 6 images back so fast, well, it might be soon indeed. Hmmm... Still, I'm guessing about 10 hours...

Yes, thanks. The higher resolution of the on-line image supports your interpretation nicely.

Posted by: kwan3217 May 26 2008, 02:09 AM

They are already getting part of a panorama back, look at lg_331.jpg. The bottom of it looks to be at -30deg, about 4m away, still out of reach of the arm.

This terrain looks rather familiar. There's a lot of fairly (or possibly very) similar terrain here in Iceland, except that it's not that flat all the way to the horizon. I need to dig up a comparison picture.

We had 279 active users at the end of EDL which is as high as I saw it but it might have nudged up a few more. Whatever the absolute number is this is the busiest UMSF has ever been while I've been watching and Doug's new server and host have both held up to the task.

Posted by: imipak May 26 2008, 02:26 AM

Looks like absolutely textbook polygonal frost heave - hopefully that means the ice will be at the depth expected. My wild-eyed speculation about landing at a tilt wasn't completely hatstand, after all, I think - it looks like there's (?) 30 - 50cm vertical relief in places.

And how's about that for fast image release? ESA eat your heart out... that is how tax-funded space science outreach should be done.

edit: yes, definite thruster exhaust effects; it looks like you could get down to ice by scrubbing with a stiff broom.

It looks like the terrain they landed in is nice and uniform. Representatives of all the elements that they see (so far) stretching out to the horizon ad infinitum should oughta be within the work volume.

Congratulations for a perfect landing, and massive thanks for getting the images put up on the web so quickly!

Fascinating and spectacular. Look at the texture of the pyramid shaped rock at half-way up to the left of the pad. Are those tiny pyramid shapes on the upper, sunlit plane part of the surface of the rock, or fragments that have frozen to the parent? If the former, that'll be what CO2 frost exfoliation looks like, will it?

O.K. Put the peanuts back in the cupboard, and let's do science!

This surface has accumulated a lot of rubble. It's poorly sorted and angular. I assume most of it is distal impact ejecta (where is the nearest young crater?), with a small proportion of meteorites. This probably wouldn't have landed here overnight. Ergo, this is not a very young surface. The rubble reminds me of the exposures north of Victoria Crater down in the spaces between dunes. So what's happening here? Rockhounds?

Edit: So does Alan get credit for the first UMSF processed image (the 3D) from Phoenix Station? Bravo!

Posted by: ToSeek May 26 2008, 03:00 AM

The landing site location is being reported (per Emily) as 68.22 north, 234.3 east, and they're calling it long, but it seems to be almost smack dab in the middle of the landing ellipse in http://www.planetary.org/image/phoenix_landing_site_usgs_map_ellipse_shifted.jpg.

I have reason to suspect those landing figures are a bit off. It seems slightly more to the north, and alot more to the east. 68.5N 233.3 E is what I've seen.


(Correction, I've seen better numbers, that match much better the numbers Emily provided. Still, it is off of on the left side of the landing ellipse in http://planetary.org/blog/article/00001431/ )

I dunno. I mentioned mine dumps on another thread, and they sure look like this in Butte, MT: no coherent pattern in rock shapes, lots of deposition of same on or near frost heave lines (it gets VERY cold there in the winter, and unexpectedly warm in the summer). I'd say that a lot of the rocks we see are being excavated by frost heaves over time.

It's been pointed out to me on another forum that there's a more up-to-date http://www.planetary.org/image/phoenix_landing_site_usgs_map_saturday.jpg, and that the location is indeed long on this ellipse. (Maybe they should have stuck with the old one!)

Posted by: fredk May 26 2008, 03:37 AM

It's just because they're shooting more or less into the low polar sun, and the bright sky is reflecting in the arrays and so they used a very short exposure.

It's not completely black (I'm assuming you mean image SOL0 281477120), but rather, very dark. I'm guessing that the surface there has a big spacecraft between it and the sun, causing it to be very dark.

Posted by: dvandorn May 26 2008, 03:40 AM

Yeah, my only thought was that it must be looking past the solar panel into Phoenix's own shadow. But I downloaded the picture and blew it up, and saw no detail in the black area at all, which I didn't expect.

Still -- lots of reflected light plus the shadow is the only explanation that makes sense, I think.

-the other Doug

Posted by: scalbers May 26 2008, 03:42 AM

Besides being a powered landing, one might note another similarity with Viking 2, that being polygonal terrain. A quick check shows this reference that delves into the causes of this in the case of Viking. Mostly it's more the larger scale polygons that are discussed however.

http://www.lpi.usra.edu/meetings/7thmars2007/pdf/3322.pdf

It seems the lander site-scale polygons may share a similar ice related cause at both sites, while the large-scale polygons at Utopia Planitia would have a different cause.

I did catch that question in the presser; nobody wants to hazard a guess about that thing yet. Understandable...but, yeah, gotta be EDL hardware, obviously.

In fact, the 'lens flare' is almost identical to the spec reflection that Oppy's backshell produced at certain angles, and IIRC Phoenix uses identical CCDs. That's pretty much a smoking gun.

Likewise, many congratulations are due on a truly brilliant recovery from the previous debacle...
which left us wondering about the risks of attempting a non-airbag landing.

Regarding the sparkly object on the horizon, recall that the interior of the backshell is very shiny silvery material (if the same as the Rovers') and those backshells both became inverted on impact, which made them so bright and caused long streaks of camera artifacts similar to what we see here.

Also, given the flat unobstructed terrian, I'll be surprised if the parachute isn't lying visible somewhere on the other side of the spacecraft, currently out of view....

I'd guess that we're seeing frost heave, plus wind deflation, plus ejecta from the crater to the east. Some pebbles look angular and some rounded. The frost polygons are reminescent of parts of Meridiani, no? Different origin, similar erosional processes.

It does look reminiscent of the etched terrain, but I think the scales are different. This is flatter than Meridiani, and the vertical relief of each polygon looks pretty invariant. So what appears to be a sea of dune crests are really the darker sides of the polygons. My estimate last night of 30-50cm height looks to be a 10x over-estimate in the cold light of, er, early afternoon. I can't wait for anaglyphs showing the arm out, to provide scale. As to erosional processes - no, I don't think there's CO2 frost cracking / exfoliation at Meridiani, just aeolian erosion caused by slow moving airborne fines and saltation.

The darker fine material along the edges of the polygons where they slope downwards towards the "cracks", has a crust-like appearance in places. Presumably that's fine dust eroded from the pebbles, and it's preferentially sorted onto the sides of the "valleys" by wind (?)

I have to say I'm quite happy Teshiener won't have to make route maps by deciphering which nearly identical dune we're parked next to today... that whole slog down to Erebus and Beagle was purgatory to me smile.gif
