http://www.esa.int/ESA
it becomes clear, that they are biased.
Their webpage, their statements very much looks like commercial advertisements.
So, I won't rely on just them saying it's a success.
What do other independent experts say ?

apparently they give press conferences, but I can't find the transcripts
of these conferences with keyword search, nor on their webpage ?!
Just newspapers quoting parts from it. More or less accurately/misleading.


I feel that these days these agencies are primarily public relation
institutes, trying to get good press for more future funding.
I remember, I first felt this with the Higg's Boson coverage.
I think it was all more objective and realistic in the last century ?!?










http://www.heise.de/newsticker/meldu...n-2457235.html

"die Mission läuft fantastisch"
Wie die ESA in einer Pressekonferenz in Darmstadt erklärte, wurden die Sensoren des
MUPUS-Instruments in den Boden getrieben, wo sie verschiedene Eigenschaften der
Oberfläche messen sollen.

Während der Pressekonferenz um 14 Uhr will die Esa ein

================================

apparently the press briefings are uploaded as videos to youtube:

as video: 1h01m
hard to understand [---microphone - gets better later]

9PM UTC + 28min+30min --> expect news at midnight middle european time

one keyphrase led to:

http://www.hertfordshiremercury.co.u...ail/story.html

I don't understand.
philae would be lost when the batteries are empty ?
Or they just have to wait longer, until the batteries reload.
So it can operate 1 more day or 4 more months times 10% = 12 days ?
Achieving maybe the most important experiments while leaving out the
more energy consuming ones.
--------edit---------
it seems that they need energy to continuously operate the system
and they can't just wait for the batteries to load without consuming
some energy.
So the hope is for tonight and maybe some more days
and then maybe reactivation in August 2015.
How that may go, and the system survives the long shutdown nevertheless,
I still don't understand.


================================

at 33:50 in that video, someone asked for the % of expected data (percent of maximum ?!) :-)
and the answer was 80%-90% !

-======================================

[after listening to the whole video, however, I get the impression that he must have weighted
the data by importance or included the Rosetta data or such. ]

the total amount of expected philae-data seems to be only ~2%, am I wrong ?

=======================================

I'd cut them a little slack, gsgs. What they've accomplished is an enormous achievement so far & apparently, a ton of data is streaming back. That alone, no matter what the data show, makes the mission thus far a success.

yes, but that's what we know already and everyone is repeating
again and again.
Thus looking like self-advertising without additional info.
See especially the last minutes in the video.

I mean, why does science have to be beautiful ?
(how they liked the pictures)
Beyond successful.

Reminds to the moonlanding, that "big step for mankind".
Turned out that the moon had been a dead end and satellites
had been the then-future of space-engineering .

Ah, but that's the EXCITING part. Data is coming in but we don't know what can be teased out of the data stream yet - that may be years & years of analysis. Perhaps the information will eventually prove to be pretty dull stuff but it will be more than we have now.

Science IS beautiful. There's a beauty in precision & for many, even more beauty in the unknowns. Look at the puzzles they present us! Reaching out for what we've yet to discover inspires the search & the word 'beautiful' probably means different things to many of the science teams involved. It can mean success, precision, pride in accuracy, in the case of images - the degree of resolution they were able to attain...

It's most necessary to engage the public if funding is to keep flowing & if it takes beauty to do so - why not?

for me science has to be logical and correct and true and objective,
not beautiful.
Beauty is for the arts, it's subjective, it changes over time.
Totally unscientific.

They are proud of being first ? But being first is just for historical records,
not of scientific importance.
Suppose another team had done the same just some months earlier,
would that diminish the merit ?

ugly comet, btw.

and my mission here is to figure out whom we can trust best
politicians ? scientists ? professors ? WHO/UNO ? statisticeans ?
journalists ? friends ?

I still don't understand. This is still a mystery, I think they failed to make that clear.

Can't they accumulate solar energy for one week or so and then reactivate again ?!
It just takes longer to load the batteries. And the system is still ready for awakening
as several statements said.
Then they think that Philae can maybe be re-activated when the comet comes closer to the sun.
When will this be ? Some speak of weeks, some of months, or "not in the next 2 months",
but most say "August 2015".
Then they rotated the solar panel by 35 degrees so to receive more sun.
Was this just for August 2015 ??

--------------------------edit-----------------
OK, I found it here:
http://spaceflightnow.com/2014/11/14...ar-exhaustion/

The batteries can only be loaded above 0C temperature.
And the sun-thing in August is unlikely,
so Philae is likely lost now. Two day's data instead of >100,
but the most important first

GSGS. I think you are just unclear on the concept.


Beauty - Definition
www.merriam-webster.com/dictionary/beauty

Merriam‑Webster
Full Definition of BEAUTY. 1 : the quality or aggregate of qualities in a person or thing that gives pleasure to the senses or pleasurably exalts the mind or spirit : loveliness.
.................
Beauty | Define Beauty at Dictionary.com
Dictionary.com

the quality present in a thing or person that gives intense pleasure or satisfaction to the mind.................................................. .......

As you clearly find "satisfaction of the mind" or "exaltation of the mind" in things numeric, charts, graphs, equations, etc, so do many people find those things in the discoveries and workings of science.

Thumbs up

Nice job Canada! A real worthwhile chore that needs to be done, IMO.

NEOSSat: Canada's Sentinel in the Sky

http://www.asc-csa.gc.ca/eng/satellites/neossat/
Launch: February 25, 2013
Status: Calibration and testing phase

(Credit: Canadian Space Agency)

The Near-Earth Object Surveillance Satellite (NEOSSat), launched February 25, 2013, is the latest in a proud family of world-leading Canadian satellites. The world's first space telescope dedicated to detecting and tracking asteroids and satellites. It circles the globe every 100 minutes, scanning space near the Sun to pinpoint asteroids that may someday pass close to Earth. NEOSSat is also sweeping the skies in search of satellites and space debris as part of Canada's commitment to keeping orbital space safe for everyone. NEOSSat applies the kind of industry-leading technology for which Canada has become known and has already demonstrated in our very successful Microvariability and Oscillations of Stars (MOST) satellite.

An Eye on Asteroids

The suitcase-sized NEOSSat orbits approximately 800 kilometers high above the Earth, searching for near-Earth asteroids that are difficult to spot using ground-based telescopes. Due to its lofty location, it is not limited by the day-night cycle, and can operate 24/7. The hundreds of images that NEOSSat will generate per day will be downloaded and analyzed by the University of Calgary's NEOSSat science operations centre. Through NEOSSat, Canada will contribute to the international effort to catalogue the near-Earth population of asteroids producing information that will be crucial to targeting new destinations for future space exploration missions.

Space Debris Surveillance

In its other capacity, NEOSSat monitors orbiting space objects to help minimize collisions between them. NEOSSat will keep track of the positions of both satellites and "space junk" as part of the High Earth Orbit Surveillance System project by Defence Research and Development Canada (DRDC). NEOSSat is the first microsatellite used for this purpose. One of the major advantages of using NEOSSat in this capacity is that, unlike ground-based telescopes, it is able to track satellites and space debris in a wide variety of locations and not be limited by geographic location, the day-night cycle, or weather. The information produced by NEOSSat will bolster Canada's contribution to international efforts to maintain the safety of Canadian and international space assets.



NEOSSat testing at the Canadian Space Agency's (CSA) David Florida Laboratory test facility

NEOSSat is a dual-mission microsatellite designed to detect potentially hazardous Earth-orbit-crossing asteroids and track objects that reside in deep space. It is also the first implementation of Canada's generic multi-mission microsatellite bus. (Credit: Janice Lang, DRDC)

NEOSSat is jointly funded by the CSA and DRDC. The satellite is built by Microsat Systems Canada Inc., with support from Spectral Applied Research and COM DEV International Ltd (formerly Routes AstroEngineering). The two Principle Investigators are Dr. Brad Wallace from DRDC and Dr. Alan Hildebrand from the University of Calgary. Dr. Hildebrand leads the Near Earth Space Surveillance project with scientific collaborators from the University of British Columbia, the Planetary Science Institute, the University of Arizona, the University of Western Ontario, the National Aeronautics and Space Administration (NASA), and Science Applications International Corporation (SAIC). Dr. Wallace leads the High Earth Orbit Space Surveillance project and the science team whose mission is to track satellites and debris in High Earth Orbit.

now the chances for a reactivation of Philae in May are being
considered "very good"
what happened, what changed

what gave the drilling




Forschern zufolge stehen die Chancen im Mai 2015 sehr gut,
dass durch die Sonne eine Aufladung bzw. Reaktivierung des
Landegerätes Philae auf dem Kometen Tschuri möglich ist.


http://en.wikipedia.org/wiki/Philae_(spacecraft)

unable to drill into the comet surface, likely due to hard ice.
The SD2 drill went through the necessary steps to deliver a
surface sample to the COSAC instrument,[46] but it was
determined that nothing entered the COSAC ovens.[49]

they speak about August, nothing about May

-------------------------------------

If all goes well and Philae does awaken, it will have a front-row
seat to the changes that take place on 67P during perihelion in
August — an event that may not have been possible for it to
observe had it not wound up somewhere that shielded it from
overheating.

Luck may still be with the little lander after all.

---------------------------------------------

=======================================
Philae's position remains unknows [2015/02/02]
==========================================
flight-leader Andrea Accomazzo at the conference DLD in Munich
gives it a 50% chance that Philae can be revived
============================================
http://www.astronomy.com/news/2015/0...lose-encounter
February 14 flyby 4 miles close

1.35*1.37km

"big news from Philae: in smelling mode it detected organic molecules"

how can that be new, when Philae has no energy since months

Rosetta's final mission will be to land next to lander Philae
Telegraph.co.uk‎ - Jun 4, 2015
Mr Taylor said 'for emotional reasons' the team would try to place the orbiter next to lander
Philae so that 'mother and child' could be reunited.
----------------------------------------------------
http://www.independent.co.uk/news/sc...-10318822.html
For 85 seconds Philae "spoke" with its team on ground, via Rosetta, in the first contact since
going into hibernation in November.
DLR Philae Project Manager Dr. Stephan Ulamec said: "Philae is doing very well: It has an
operating temperature of -35ºC and has 24 Watts available." "The lander is ready for operations."
We have also received historical data
There are still more than 8000 data packets in Philae’s mass memory which will give
the DLR team information on what happened to the lander in the past few days
discovered organic molecules on the comet
may have found the exact location

There is a YouTube blogger who claims the 67/P Churyenkov COmet is part of the corpse of a prehistoric Giant, and the coma of the comet is mainly VOCs that are uncombusted meat smoke.
