Make a mosaic from Rosetta’s comet pictures. ESA/Rosetta/NAVCAM
ESA’s Rosetta is now taking images from just 61 km from comet 67P/Churyumov-Gerasimenko. That is close enough so Rosetta is imaging the comet in about quarters.
The above four-image mosaic is featured at the Rosetta blog was taken on 31 August 2014. It’s really not quite a mosaic yet If you look at the four-panels you will see some overlap. The images were made from 20 minute exposures and there is also some rotation from the mutual movement of Rosetta and comet.
We, the public are invited to create a mosaic from them. Rosetta Blog has the four individual frames on the page for downloading which I have done. Just scroll down the page linked above to get the individual shots.
I have everything loaded into a imaging program and working on my mosiac. The rotation is creating quite a challange!
Give it a try. I’ll post my effort if I can get anywhere with it.

A picture of the Martian landscape but not from Curiosity. This is the the Navcam view from Opportunity.
Yes, Opportunity is still doing science on Mars after 3,749 Martian days when this image was taken (10 August 2014).

One of the nice things about this time of year is the clearing skies. I mean really clear skies, cooler temperatures and stable “seeing” kind of clear. If you have a telescope you probably know exactly what I mean.
We have a few nice pairings of stars / planets / moon. These pairings are especially nice for casual viewing and interesting conversation with those friends who might not otherwise notice and I find they almost always will look.
I don’t always get the best view of the zodiacal light right here because of the hills to my east but I can see it. If I’m on the road at the right time I can drive to a good location and stop long enough to let my eyes acclimate some and sip my coffee or tea for a short time and appreciate the view. Yes, I know coffee / tea doesn’t help the process, but it does make it more enjoyable.
It’s been a busy week at NASA and was pleased to have see the news about the Space Launch System heavy-lift rocket in video format.
A good episode and as always you can get a more in-depth account of the topics at TW@N
Voyager’s look at clouds on Neptune. Credit: NASA Jet Propulsion Laboratory / NASA Planetary Photojournal
The bit of an interlude in the ESA’s Comet watch blog is a good time to look at some of Voyager 2’s images of Neptune. This is one of my favorites. I don’t really know if there is more than coincidence that the New Horizon’s spacecraft crossed the Neptune orbit 29 years almost to the day after Voyager started its Neptune encounter.
There is a lot of comparisons being drawn between the New Horizon’s and Voyager missions. Hey I’m on board with it. If I had my way there would be a “Le Verrier” or “Galle” spacecraft, a Neptune analog of the Cassini spacecraft in orbit right now.
In case you were wondering what was going on with Rosetta, everything is fine. Mission managers are looking at images from as close as 50 km trying to select the best landing spot. New images will be posted shortly.
This image comes from NASA’s Solar System Exploration (and Planetary Photojournal) site:
This Voyager 2 high resolution color image, taken 2 hours before closest approach, provides obvious evidence of vertical relief in Neptune’s bright cloud streaks.
A look at the Space X Falcon 9 rocket’s first descending through the atmosphere and soft landing in the Atlantic Ocean.
A little trivia: The Falcon 9 first stage is powered by Merlin Engines supplying thrust greater than FIVE 747’s at full power at launch.

Curiosity’s HazCam testing Bonanza King. Image Credit: NASA/JPL-Caltech
Last week I mentioned the Mars Science Laboratory – Curiosity was at an interesting rock and mission managers were evaluating it to see if it would be a good choice for a sample collection (see the post).
Before there is a sample collection Curiosity uses the mini-drill procedure to aide in evaluating the location. Part of using the percussive drill for making a starter hole, probably akin to a hammer drill many of us use now and then. During the starter hole step Bonanza King moved a little bit and the protective software on Curiosity sensed it and stopped the procedure.
Mission managers decided to move on towards the long term goal of reaching Mount Sharp. Maybe they will find something interesting along the way.

ESA’s Landing Site Selection Group met over the past weekend and identified five possible landing sites for Rosetta’s Philae lander on Comet 67P/Churyumov-Gerasimenko. Three of the sites are on the smaller lobe and two on the larger one.
The original ten candidate sites were all marked with a letter designation, A to J and the group was narrowed to five at the meeting (A, B, C, J, I). The letters are only for identification and do not denote any preference.
After a detailed review for physical hazards and even long term illumination are complete, a primary landing site will be selected on 14 September. A secondary site will also be selected at that time.
Personally (today and very subject to change) I like:
You might think this sounds a little dubious, yet when I heard this on the news (amazed) I said “Ah but this sort of thing is not necessarily new”. Remember the Surveyor 3 and Apollo 12 story?
Not to mention this.
I remember this quite well. I was watching the video data being rebroadcast on the ham bands and I was decoding them on a ROBOT 400 SSTV converter – good times!
Truly an epic mission.
