Asteroid 2012-TC4 12th Oct -A third closer than indicated before

Image is from https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2012%20TC4&orb=1

Previously and in my last post the closest distance was 3.0e-4.

Today (11th October 2017) the JPL diagram is giving a distance of 2.0e-4.

Therefore the asteroid, 2012-TC4, is showing 1/3rd closer than calculated before by JPL

2.0e-4 = 0.000200 AU or 18591 miles from the CENTRE OF THE EARTH

In km this is 29919.5 from Earth’s centre so minus the radius of earth of 6371 KM:

23,548.5 KM from Earth’s surface

This is well below the orbiting height of satellites.

The orbit of a weather satellite is about 36,000 kilometres from Earth’s surface.

This includes communications satellites as I posted previously.

 

 

Asteroid 2012 TC4 – same altitude as communications satellite

I thought it’s worth mentioning that the asteroid 2012 TC4 is estimated to be at it’s closest to us on October 12th 2017 and the JPL orbit diagram is giving a minimum altitude of 3.0E-4.
In case you are unable to view the orbit diagram due to java problems, there are images below.
The JPL link for this asteroid is https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2012%20TC4;orb=1;old=0;cov=0;log=0;cad=0#phys_par

I am no mathematician but I did manage to work out the distances.
On 12th October 2017 this asteroid 2012 TC4 will be a distance of 3.0e-4 AU.
3.0e-4 AU equals 0.00030 AU.
This equals 27886.7 miles.

That’s 44879 km and the distance is given from earth’s centre so minus the earth radius of 6371km, it gives an altitude from average earth surface of 38508 km same altitude as Molniya-3 communications satellite.

Other similar satellites are in the same altitude range, for example, Bulgaria launched their first communications satellite in June this year according to this article, http://uk.reuters.com/article/us-space-launch-bulgaria/bulgarias-first-communications-satellite-launched-into-orbit-idUKKBN19F05U
“The satellite will be positioned into orbit at 36,000 km (22,000 miles) above the Earth and be operational up to 20 years.”

This is pretty close to 38508 km.

On the JPL website there is an error margin for the fly by distance of 2012 TC4:
Orbital margins for 2017-Oct-12 05:42 distances from Earth calculated on 2017-Sep-05
Time uncertainty 00:01
Nominal distance 0.000335370338966099 AU
Maximum distance 0.000333848671968589 AU
Minimal distance 0.000336892964761902 AU
As shown in the images below, the orbit diagram is currently giving 3.0e-4 for closest to earth and this equals 0.00030 AU

The Arrangers at the Place of Books, Writing on the Walls (and another volume)

This is a view of the Place of Books as Curiosity was moving away from the hill.

This is how I see it: After the clerics / librarians had passed into oblivion there came the arrangers. The arrangers seeded onto a planet with little landmarks and so they arranged what had been left behind to make their landmarks, because they travelled by air. That’s why they made faces and other shapes out of the hill tops using whatever was lying around, be it gold or wood, stone or paper….
This is the top of the hill on the approach to the Place of Books. It’s very pretty, there are a couple of books here, but the landscape art was so nice I left them out.

There is a video at the end of this post with writing on the wall and a nice big book with torn spine shown in this small image .

 

This is the hill top as it is in the RAW image http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=1601ML0081530000505322E01_DXXX&s=1601

Rather than make a gallery I decided to just upload the pictures so that you can scroll through them. I think the quality is better that way.

First, Top of the Hill – different filters show different details

There are a couple of books in the middle of this next one

Last but by no means least – The writing on the stones and a few more books and objects –

Shot in the Head on Mars – Video posted

I hadn’t posted a video with the blog post about the Brain on Mars that has a foreign body in the side of it, so here it is, it’s an update to the original posting http://www.afterzen.co.uk/wanderings/injury-to-a-detailed-mammal-brain-in-a-curiosity-image-sol-0580/

Birds on Mars? sol 1601- Today’s Curiosity images

Screenshot From 2017-02-06 22:42:59

birds_sol_1601

The first time I noticed it.

This is from the same image as the structure below

This is what I was looking at.

The same image is lightened below

In the top part of the shadow of the “roof” is a grey shape that seems to be flying past.

Below is the whole image smaller size and I have altered the levels of light. The bird shape is in the middle at the far left side.

The original image is at http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NRB_539621172EDR_F0603162NCAM00259M_&s=1601

It’s also visible in this image from the other NAVCAM http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NLB_539621172EDR_F0603162NCAM00259M_&s=1601

I was really surprised so looked around the other images and found this:

This is lightened again. I think I can see the pale outline of a wing. The body position is different from the first one.

Here they are side by side

This short silent video is a forensic exploration of the second of these bird images:

Here’s where it begins to get strange.

The second bird is from this image, lightened here and smaller size. it was taken a couple of minutes later. I have drawn a ring around the bird:

The source for this is at this link: http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NRB_539621234EDR_F0603162NCAM00260M_&s=1601

On another NAVCAM-Left image bird one is visible, standing on the white square  thing:

It’s in the right-centre of this image, also smaller size and lightened: the link is here http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NLB_539621148EDR_F0603162NCAM00259M_&s=1601

Let’s compare the three images:

    The last one has been enlarged a bit more than the others. I think it has moved a little.

It isn’t there in this one:

found at:

http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NLB_539621196EDR_F0603162NCAM00260M_&s=1601

 

All three birds were in the distance. The clearest image after applying levels was the second one shown here in the RAW original levels of light and dark http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/01601/opgs/edr/ncam/NRB_539621234EDR_F0603162NCAM00260M_.JPG

It is standing on a log shape. http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/01601/opgs/edr/ncam/NRB_539621234EDR_F0603162NCAM00260M_.JPG

Then I found this in another image:

This is from http://mars.jpl.nasa.gov/msl/multimedia/raw/?rawid=NRB_539621588EDR_F0603162NCAM00653M_&s=1601
“This image was taken by Navcam: Right B (NAV_RIGHT_B) onboard NASA’s Mars rover Curiosity on Sol 1601 (2017-02-06 03:17:36 UTC).”

There is another image taken at exactly the same time – “This image was taken by Navcam: Left B (NAV_LEFT_B) onboard NASA’s Mars rover Curiosity on Sol 1601 (2017-02-06 03:17:36 UTC)”

Actual size  enlarged

I looked at this and wondered if the missing blacked out part of the other image had something like a bird in it, and if so could this obscure image have any clues?

I have lightened it by levels and drawn where I saw the outlines of the image:

I have demonstrated how I did this – without it being an imaginary concoction, and shown some of my exploration in this video below which is about 15 minutes or so

All these images are

Tiny, fragile and hidden thing in a Curiosity Image, what is it?

Curiosity has sent this image of a fragile, delicate looking small device placed by someone on top of a large metallic object.


I found this large object and wondered what it is. It’s out of place. I wondered if something fell off the rover because it looks metallic. There’s a few marks indicating the rover might have investigated it perhaps. It’s too shiny and solid to be clay. Clay wouldn’t keep it’s shape unless it was fired and the surface looks shiny and metallic not glassy or glazed.

Looking closer I was pretty shocked to see such a delicate tiny thing on the top of it. It has the look of something meant to transmit or receive signals. It can’t have survived geological disturbance so how did it get there? What is it for? Who made it and put it there? Are there little people on Mars?
