Enceladus & Europa: profusely populated with microbial life and The 3 Monkeys at NASA
#1
...

We need a thread on Enceladus and Europa. 
They are too important for NASA to ignore anymore.
They should send a mission to Enceladus,
before they send a mission to the clouds of Venus,
or a submarine to Titan.
Europa should have been landed on before NASA performed the Pluto Fly  Hi Bye. 

Fly  Hi Bye's are bullshit missions.
You either go into orbit or land there.

These moons with subsurface oceans which will produce massive evidence of life.
Just like Mars will,
when NASA actually decides to really look for life there,
rather than in "el cheapo" missions that are designed to pretend to find evidence of life.

The 3 monkeys at NASA Whip
are
See No Life
Hear No Life
Speak No Life

These NASA monkeys run the Decadal survey corruption of space mission funding.
Otherwise we would already have missions landing on the two moons,
if NASA really wanted to find evidence of life.

But you don't want to hear about all that NASA nonsense, it is old hat and been repeated many times.
Long story made short,
we need priority missions to Enceladus and Europa,
certainly before anything goes to Venus or Titan.

So aside from the NASA mumbo jumbo  Naughty about wanting to find life on Mars or elsewhere,
we 
also
KNOW
there is life on Europa and especially Enceladus.

So I simply want a spot to warm up any developments for Europa and Enceladus.


Enceladus' Tiger Stripes glow red in new global mosaic
https://newatlas.com/space/enceladus-tig...al-mosaic/

excerpts from the article:
Quote:Data captured by the Cassini spacecraft has been used to create a global infrared map,
of the Saturnian moon Enceladus. 

The icy world plays host to the dramatic "Tiger Stripe" vent formation Whip
 which leads down to a massive subsurface ocean that, 
it's long been speculated, 
could play host to extraterrestrial life.

Cassini captured stunning imagery of the icy moon, 
and a horde of data that scientists are still picking through today, 
long after the probe ended its mission by plunging into the swirling depths of Saturn’s cloud surface.

It was from this data,
that scientists constructed a new global infrared mosaic of Enceladus’ frigid surface. 
More specifically, 
researchers used data collected by Cassini’s Visual and Infrared Mapping Spectrometer, 
which was capable of characterizing the temperature, 
makeup and crystallinity of the water ice grains that form the moon’s surface.

The team took this information and performed photometric corrections Hmm2
which takes into account and corrects variations in the data 
caused by different surface materials, 
their shape, 
and the angle at which they are viewed. 
These corrections revealed new details, 
and highlighted deviations in the composition and state of the moon’s surface.

In the resulting infrared views of Enceladus, 
the moon’s iconic Tiger Stripe formation can be seen to glow an angry red, 
which is indicative of the presence of newly deposited freshwater ice. 

This fresh material would have been drawn from Enceladus’ subsurface ocean, 
and ejected from the vents in the moon’s surface to settle on the surrounding terrain.

In this image they name the "Tiger Stripes" of Enceladus.
They must be running out of names?
Seems like the better option would be to name them all Egyptian, or all Iraqi.
Bogus bullshit names.
NASA names surface water ice heat anomalies on Enceladus,
after cities on Earth baking in the desert sands. 

Come on man.
Baghdad and Damascus?   Pennywise

What about Earth water deities?  Slap2

100,000 Ice Blocks Mapped Out at the South Pole … of Enceladus


Quote:Ever since the Cassini space probe conducted its first flyby of Enceladus in 2005, 
the strange Saturnian moon has provided us with a treasure trove of images and scientific wonders. 

These include the jets of icy water vapor, 
periodically bursting from its south pole, 
the possibility of an interior ocean – which may even harbor life – 
and the strange green-blue stripes located around the south pole.


These stripes are essentially four fractures bounded on either side by ridges,
that appear to be composed of mint-green-colored ice. 

Known unofficially as “tiger stripes”,  
these surface fractures have become a source of interest for astronomers, 
since they appear to be the youngest features in the region.

Recently, between these stripes, 
over 100,000 ice blocks were observed, 
and they are a further source of wonder. 
Scientists with the Division of Geological and Planetary Sciences at the California Institute of Technology 
were able to map out the locations of these blocks, 
in the hopes of determining just how they got there.


[Image: enceladus_stripe_11-30-10-1.jpg]



The preliminary results of their work reveal that ice blocks in the southern hemisphere
are most concentrated within the geologically active South Polar Terrain (SPT)
and chiefly concentrated within 20 km of the tiger-stripe fractures. 


Elevated View of Enceladus’ South Pole
[Image: enceladus1.jpg]



To ascertain just how these ice-blocks formed and evolved, 
and how they came to be distributed in the southern region, 
the team considered various mechanisms. 
These included the well-known aspects and features of the moon – 
namely its seismic activity, impacts by meteors, and volcanic eruptions – 
but also the possible roles of tectonic disruption of the icy surface mantle and ice slides.

Ultimately, they concluded that impact cratering as well as slides, 
perhaps triggered by seismic events, 
could account for a majority of ice-block features within the inner SPT.

However, they also noted that cryovolcanic activity – i.e., 
the ejection of icy material caused by sub-surface volcanic eruption, 
and the condensation of ice around the eruption vents – could not be ruled out. 

They noted that the pervasiveness of fracturing on many size scales, 
the sheer number of ice blocks in the inner SPT, 
and the occurrence of linear block arrangements that parallel crack networks along the flanks of tiger stripes, 
would seem to indicate,
that tectonic deformation also played an important role.

Furthermore, 
they postulated that nearer to the warm tiger-stripe fractures, 
sublimation likely leads to erosion and disaggregation, which plays a role as well.

Last, they noted that the relative scarcity of blocks beyond the bounds of the SPT, 
particularly on old, cratered terrains, 
may be attributed to ice grains accumulating on the surface over time,
rather than the same causal factors that led to the 100,000 blocks observed around in the southern region.

In short, 

the CIT team believes that the unusual ice-block formation around Enceladus’ south pole,
is chiefly the result of impacts from meteors or comets   Naughty   and seismic activity Nonono
but, 
that the peculiar activity in this young region of the planet – 
such as volcanic eruptions from the hypothesized interior-ocean – may also play a role.

As you can see from the last post,
NASA named this moon's :  "Tiger Stripe" heat anomalies,
where the Enceladus vents spew water vapor from the south pole,
and with a submerged ocean under the ice,
after:
Earth cities in sandy desert environments.

Sorry, I cannot stand for that kind of nonsense.
They must either have idiots at NASA naming solar system planetary and moon geologies,
or they are purposely trying to divert attention from Enceladus,
with stupid names.

So I proposed -- ancient Mesopotamian water deities -- as a more valid alternative.

This is what Enceladus could look like, and generate far more public interest.

The Cradle Of Future Civilization On Enceladus

2220

edit --
to be clear about "the cradle of future civilization" -- on Enceladus,
there will be cradles of blossoming civilization on Mars, and on Europa, and so on.
Mesopotamia is my candidate for the one on Enceladus.
Another will be at Occator crater on Ceres.
It is perfect spot for a giant artificial dome to cover the entire crater,
with suburb colonies sprawling outside the crater in an eventuality.

but if NASA doesn't get their act together,
the Moon might get renamed China Town. Damned

Ever since the Mole failed on Mars all I see is NASA excuses.

It is kind of like ... Mission Rewrite DuJour   
Original mission plans ---> Kickbut <--- New mission cost overruns means go back and redesign the science cheaper 

The mission to Europa is falling apart at the seams.

Rocket limbo complicating NASA's Europa Clipper mission
Clipper team members say they need a decision soon.



Quote:NASA's highly anticipated mission to the Jupiter ocean moon Europa needs a rocket — 
and soon, 
the project's planners say.

The Europa Clipper probe is scheduled to launch in 2024 to study the Jovian satellite, 
which harbors a huge sea of liquid water beneath its icy shell. 
Clipper will assess the habitability of that buried ocean and perform a number of other tasks, 
including scouting out promising sites for a future life-hunting lander mission.

Congress has long mandated that Clipper launch atop the Space Launch System (SLS), 
the giant rocket that NASA is developing Whistle
to send astronauts toward the moon and other distant destinations. 
But SLS has been plagued by delays and cost overruns, 
and the megarocket isn't slated to debut until late 2021.

That initial mission will launch NASA's Orion capsule,
on an uncrewed flight around the moon for the space agency's Artemis program of lunar exploration. 

SLS and Orion are key elements of Artemis, 
which seeks to land two astronauts near the moon's south pole in 2024 
and establish a sustainable human presence on and around Earth's nearest neighbor by the end of the decade.

Given the commitment to Artemis and the relatively slow pace of SLS development, 

the rocket's availability Whip

for an on-time Europa Clipper launch Whip

is in serious doubt Slap2
NASA's Office of Inspector General concluded last year.

This concern has apparently bubbled up into the U.S. House of Representatives. 
The House's proposed 2021 NASA budget, 
which was released in July,
directs the agency to launch Clipper by 2025 and the Europa lander by 2027. 

The proposal dictates that SLS be used for both missions "if available." Naughty

That wording leaves the door open for a commercial alternative — 
perhaps SpaceX's Falcon Heavy, 
the operational rocket that comes closest to SLS' power 
(though SLS' power remains purely hypothetical until it flies).

The Europa Clipper team has been planning for both launch contingencies. 
But the mission cannot stay in this limbo for much longer, team members said.

"We really need a decision by the end of this calendar year 
in order to continue to mature the spacecraft development," 
Europa Clipper project manager Jan Chodas, of NASA's Jet Propulsion Laboratory in Southern California, 
said on Wednesday (Sept. 2) during the fall meeting of NASA's Outer Planets Assessment Group.

The mission team is already working toward a big milestone at the end of the year: 
Clipper's critical design review (CDR), 
the final vetting hurdle 
to clear before full-scale manufacturing begins, will be held in December.

The CDR "was originally planned to be earlier, 
but, 
because of the launch-vehicle uncertainty, 
we've delayed it until the end of the year," Chodas said.

The roughly $3 billion Europa Clipper mission has been dealing with other complications as well. 
Costs have ballooned on several science instruments, for example. 
And the coronavirus pandemic has had a significant impact, 
the extent of which is still being assessed, Chodas said.

The team is aiming to have Clipper launch-ready in early 2024. Nonono
Liftoff will occur in summer or fall of that year,
if all goes according to plan.

Clipper will eventually settle into orbit around Jupiter. 

The probe will study Europa in depth during a series of roughly 50 fly   Hi  byes, 
which will take place over nearly four Earth years. 
Clipper will use nine science instruments to characterize Europa's ocean, 
measure the thickness of the moon's ice shell and hunt for plumes of water vapor wafting from the surface, 
among other tasks. 
The probe will also look for good touchdown sites for the Europa lander, 
which is still a concept mission, not an official NASA project.

Cost growth prompts changes to Europa Clipper instruments

Cost overruns on three instruments for NASA’s Europa Clipper spacecraft,
led NASA to consider dropping them from the mission Scream 
and ultimately
requiring significant changes to some of them.

At a July 9 briefing to the Committee on Astrobiology and Planetary Sciences of the National Academies, 
NASA officials said they recently conducted “continuation/termination reviews”  Horsepoop
for the three instruments: 
a camera, 
infrared imaging spectrometer 
and mass spectrometer. 
Those reviews were prompted by cost overruns on those instruments.

“We’ve been struggling on cost growth on Clipper for some time,” 
said Curt Niebur, 
program scientist for the mission at NASA Headquarters. 
“Overall, we’ve been largely successful in dealing with it, 
but late last fall, 
it became clear that there were three instruments that experiencing some continued and worrisome cost growth.”


[Image: europaclipper-2016-879x485.jpg]



The outcome of the reviews, he said, 
could have ranged from making no changes to the instruments to, 
in a worst-case scenario, 
terminating the instruments.  Pennywise

The leadership of NASA’s Science Mission Directive recently decided to keep all three instruments, 
at least for now.

“We are flying the entire payload, 
and every decision in the memo is intended to maximize the chance, 
that we will retain the entire payload through launch,” he said.

However, there will be changes to some instruments, 
particularly to the Mass Spectrometer 
for Planetary Exploration/Europa, or MASPEX. 
That instrument is designed to measure the composition of the Jovian moon’s very tenuous atmosphere, 
and any plumes of material that erupt from its surface.

MASPEX was suffering serious cost and schedule problems, 
Niebur said, 
a situation “that deteriorated further” Whip
during and after a risk assessment earlier this year.
 “It was really felt that significant relief was needed to avoid termination of MASPEX,” he said.

“We pulled out all the stops” to keep the instrument on the mission, 
he said, 
because of its importance in evaluating the habitability of Europa. 
The instrument now has a cost cap and its risk classification has changed from Class B, 
with a low tolerance for risk, 
to Class D, with a greater acceptance of risk. Nonono

The mission’s overall “Level 1” science requirements will also be modified Scream
to reduce the mission’s reliance on MASPEX and the instrument’s performance requirements.

NASA also decided to replace the principal investigator (PI) of MASPEX,
 which had been Hunter Waite of the Southwest Research Institute. 
Niebur said that the institute, 
which retains responsibility for developing the instrument, 
has appointed an acting PI, 
Jim Burch, and will nominate a permanent replacement to be approved by NASA Headquarters.

Niebur praised Waite for an “incredible job” on MASPEX,
 but that new leadership was needed to keep the instrument on the mission.
 “To get it the final 10 yards to the end zone,
 we need somebody with more experience,” he said. 
“Jim Burch is a good match for that.”

A second instrument, the Europa Imaging System (EIS), will also get a cost cap. 
The camera system was suffering technical issues he described as not particularly surprising, 
but those problems, combined with cost growth, posed a greater concern.

One option considered by the agency was to remove a wide-angle camera (WAC) from the instrument 
“because it has less intrinsic scientific value” 
than its narrow-angle camera, Niebur said. 
Instead, NASA decided to keep both cameras and place a cost cap on EIS, 
with instructions to prioritize development of the narrow-angle camera. 
The mission’s Level 1 requirements will change to reduce reliance on the wide-angle camera.

“If you have to cut corners on the WAC, that’s OK,” he said. 
“In the worst-case scenario, 
if we have to go forward without the WAC, we will.”

The third instrument, the Mapping Imaging Spectrometer for Europa (MISE), 
did not see significant changes. 
Niebur said that reviewers found its design had stabilized after past issues which affected its cost and schedule. 
“The decision for MISE was straightforward,
to adjust the cost and the schedule and to simply continue on,” he said.

These reviews are not the first time that instruments for the mission have faced problems. 
Last year, NASA terminated a magnetometer instrument called ICEMAG 
because of continued cost growth and technical problems. 
The agency replaced it with a simpler and less expensive magnetometer with a different PI.

Some members of the committee wondered if the instruments were being singled out,
for the overall cost growth in the mission, 
which as an agency cost commitment of $4.25 billion. 

Jan Chodas, project manager for Europa Clipper at the Jet Propulsion Laboratory, 
said that the instruments used about the same amount of budget reserves as the spacecraft, 
or about $70 million each. 
However, she said that dollar amount was a much larger fraction of the overall cost,
to build the instruments than for the spacecraft.

Chodas said that Europa Clipper now has a launch readiness date of 2024, 
a year later than plans announced last year

There are launch opportunities in the summer and fall of 2024 for the mission, 
including an August launch window using the Space Launch System 
that would send the spacecraft directly to Europa. 
An October launch window would require Mars and Earth gravity assists, 
extending the flight time, 
but could also be done by commercial launch vehicles such as SpaceX’s Falcon Heavy.

NASA remains engaged in a debate with Congress about how to launch Europa Clipper. 
Congress has for several years mandated the use of SLS for the mission 
as well as a follow-on Europa lander mission. 
NASA has requested the ability to use other vehicles, 
citing cost savings and the lack of available SLS vehicles, 
which for the next several years are devoted to the Artemis lunar exploration program.

A House appropriations bill introduced July 7 would give NASA some flexibility, 
requiring Europa Clipper to launch on SLS only “if available,” 
a provision not found in previous spending bills. 
However, some in Congress continue to press NASA to use SLS on the mission. 
“NASA must increase the pace of SLS production to ensure an SLS is available for the Europa missions,” 
said Rep. Robert Aderholt (R-Ala.), 
ranking member of the commerce, 
justice and science appropriations subcommittee, at a July 8 markup of the bill.

Chodas said that while the Europa Clipper program has been working to support launches both on SLS and alternative vehicles, she needs a decision soon on which vehicle will launch the spacecraft. That uncertainty forced the program to delay its critical design review from August to December of this year.

“We really need a definitive decision on that launch vehicle by the end of this calendar year,” she said.
