A sundial on Curiosity?

When I saw the first reports of this on Twitter I thought it was a joke. A sundial on Curiosity? Just in case the computer packs up they can still tell the time? I thought some wag was pulling our collective legs with a photo of one of the rover’s antennae.

But, turns out this is something like a sundial. Its a Marsdial – actually a calibration target enabling photographs to be corrected for colour. BIll Nye, from the Planetary Society, describes its role in Curiosity’s Marsdial is on Mars!

“As I’m sure you’re aware, geologists love rocks, and they especially love the rocks on Mars. The first thing they all want to know about a rock is what’s it made of. For that, it’s good to just take a look at the color of the rock surface. When everything is being done on the alien landscape of another world, it’s easy enough to electronically get the color wrong, or not quite right. To that end, artists, photographers, and a few scientists have noticed that by looking at the color of a shadow on a neutral white or gray background, you can infer the color contributed to the scene by the sky.

On Earth, shadows take on a sky blue tinge (what I like to call “cerulescence”). On Mars, it’s a salmon color (what I like to call “arangidescence”). And so, the MarsDials bear a small metal post that casts a shadow onto some white and gray rings of known value or grayness.”

The NASA animation above is made up from four Mastcam images of the calibration target — the Marsdial. They were taken on Curiosity’s sol 3 (August 9, 2012) over a period of about 8 minutes. In that time, the shadow moved slightly, marking time on Mars with a sundial. (You may need to click on the photo to see the animation).

Scientific shift work

Some of the people on teams managing the rovers on Mars call themselves “Rover drivers” or “Mars drivers.” Of course, things are not that simple. It is not possible to drive a vehicle on Mars in real-time from Earth. Instead, computer code must be uploaded to enable the vehicle to carry out planned manoeuvres, analyses, etc., autonomously.  And the computer code can only be written after the results of the previous commands are known.

In practice, this involves large teams of engineers, software experts and scientists. Each team has their own work – and the teams need to interact to plan the rover’s work, iron out priorities, and deal with problems. This work has to occur at strange times, and with deadlines, to fit in with the activity and day/night programme on Mars. Energy limitations means that the rover usually does not operate during the Martial day.

So all this work, the meetings of each team and their joint meetings, and decisions about planned activity must take place before the rover “wakes up.” And because the results from the previous day’s activities feed into this detailed decision cannot be made and code written until after that data has been downloaded and analysed.

The graphic above was shown in one of the recent Mars Science Laboratory – Curiosity – media briefings. It indicates the time line for the Laboratory to be active (“awake”), the downloading of data via the Mars Odyssey and Mars Reconnaissance orbiters, assessment of data, planning of future activity (particularly that for the next day), interaction of engineering, scientific and software teams, integration of plans, validation and approval and then the sending of the new commands to Curiosity as it “wakes up” for the new day.

I note they have even left a brief time gap “margin” to handle unforeseen problems.

It must be fascinating to work in large teams like this on scientific projects. And I am sure there are also political and emotional problems that need management as well as the engineering, scientific and software problems. Apparently with groups managing Mars rovers the shift-work, and the drift in shift times because of mismatch in the length of the Earth day and the Mars sol, causes “jet lag.” So the emotional and human issues resulting from this also need management.

Andrew Kessler gives an idea of the procedures involved in managing Mars rovers and landers in his book Martian Summer: Robot Arms, Cowboy Spacemen, and My 90 Days with the Phoenix Mars Mission. This is based on his own experiences as a journalist embedded in the teams managing the recent Phoenix lander. It’s a bit of an eye-opener – at least for someone who hasn’t worked in such large scientific teams before.

See Working on Mars for my review of that book.

Cynical evangelisation of children

All parents are concerned when they send their children out into the world. We all hope that our schools, and other places our children go, are going to be safe. We are rightfully shocked when we find adults entrusted with the care of children have actually been preying on them.

Sexual predators get the headlines. But children can also be subject to unhealthy interest of adults who interests are more political or ideological than sexual. I am beginning to think we should look at the way religious instruction operates in our public schools as an example of this unhealthy interest.

There has been a lot in the media lately about “bible in schools” and similar programmes. Simon Greening, the chief executive officer for the main provider of these religious instruction programmes (the Churches Education Commission),  has been assuring everybody that their interests are not evangelical. They are not trying to convert children – just educate them about values (see Their mission – values or advancement of religion?). It hasn’t helped him that other spokesmen for his organisation have presented a different story – admitting that they see religious instruction in public schools as a great opportunity for their religious mission. There has even been talk of creating disciples out of children in these religious instruction classes.

George Higinbotham (@streligionVIC) a recent commenter here pointed me to a document which is very relevant to this issue. Partly because one of the drafters of the document is Mitch Jordan who is currently Chairperson of the CEC board. But also, and more seriously, the document outlines a cynical programme for the evangelisation of children that seems to actually now be in place in New Zealand.

The document is Evangelisation of Children.” Prepared several years ago, it’s seen as part of a general plan of world evangelisation. I’ll present some extracts from the document and compare them with what is actually happening here.

Identifying children as a fruitful group for evangelisation

We are all aware of the importance dogmatic religions place on the early indoctrination of their own children. But this document describes the same approach to your children.

“Children represent arguably the largest unreached people group and the most receptive people group in the world. “

“Children are more open and receptive to the gospel than at any other time in their lives.”

„ “Between the ages 5 and 12, lifelong habits, values, beliefs and attitudes are formed.  Whatever beliefs a person embraces when he is young are unlikely to change as the individual ages.”

„ “If a person does not embrace Jesus Christ as Saviour before they reach their teenage years, they most likely never will.”

“The data show that churches can have a very significant impact on the worldview of people, but they must start with an intentional process introduced to people at a very young age.  Waiting until someone is in their teens or young adult years misses the window of opportunity.”

“Unevangelised children generally become adults who see no relevance of Christian faith to real life, make no contact with a church, who live and die without knowing that Jesus offers eternal life.  Ineffectively-evangelised children in our churches become ‘well-intentioned, inadequately nurtured, minimally equipped secular people who dabble in religious thought and activity.”

The organisations currently operating religious instruction classes in public schools all seem to express the same belief in the importance of reaching young children.

Evangelisation of children, by children

The document cynically advocates to: “invite children to be active participants in the task of evangelization:”

“The focus of mission and the call to mission do not have any age limitations.”

“The work of mission can be shared by a generation of children equipped to be faithful witnesses for Jesus”

“peer evangelism among young children – one kid leading another kid to the foot of the Cross for a life-changing encounter with Jesus”

“Children bring unique gifts to the task of evangelization.  For example, they have access to thousands of children outside the church – and are often the only means of reaching these children.  They have a simple faith that is attractive.  They put their whole heart into reaching out.  Children will do the job of evangelism in simple obedience.  Even adults will listen to children because they are perceived to have no hidden agenda.”

“Challenge children to be witnesses and challenge them at an early age”

“Marketing companies have recognised that children have the power to enthuse others. Imagine if the church worldwide could harness the enthusiasm of children and encourage them to tell their friends and get them involved as well.”

“existing worldwide initiatives that focus on child evangelism could encourage children who are already churched to take ownership of the event – be trained to share their testimonies, invite their friends and do discipleship.”

What a horrible task to place on children – that their friendships be destroyed by the need to evangelise.

Action plans for influencing children

The action plans advocated in this document are very similar to what is occurring in New Zealand:

“ACTION PLAN for the local church: Think about how a values-based programme might give unexpected access to local non-Christian communities (e.g. schools) and become a vehicle for evangelization”

Provide “Quality interactive websites for children” and  Email, chat-rooms and ‘mailbox clubs’ which are tools to help children to follow Jesus.”

“Going to where the children are in their world.  In every continent, there are more children outside our churches than inside: we dare not be content with hoping that children will come to visit a strange place with strange rituals and unknown people.  Many children require stepping stones before they can cross the cultural barriers represented by church as it is now.”

It advocates “specific application to the evangelization of children in different social contexts.” And “Working within the web of relationships to which the child belongs – friends, gang, family.’

Church groups in New Zealand are forming special relationships with public schools as the document outlines. These also include web sites and email clubs for children who are initially contacted through the religious instruction classes. the Cool Bananas Kids Mailbox Club operated by the Cool Bananas group in Tauranga is one example. The same group offers an Annual 5 day Adventure Camp. Other local groups do the same.

There is a video in my post What really happens in religious instruction classes? describing how Pentecostals in Australia use such camps to further indoctrinate children attracted through religious instruction classes at school.

Tactics – winning the cooperation of care-givers

“For the local church to plan evangelism that minimises offence and maximises effectiveness, it must:  1. Commit to long-term effort, preferably involving a partnership of interested people such as teachers or health care workers”

“6. Be prepared to work within the limitations while taking the opportunities”

“1. Use the window of opportunity  Parents may well have an interest in introducing values, ethics or belief frameworks to their young children.  The church will be one option they may consider.  Make it an attractive one!”

„ “Church members join school boards, volunteer for sports coaching”

This is a cynical agenda for the infiltration of places our children attend with the sole purpose of evangelisation.

Confidence of their plans for your children

“We can bring about a transformational shift even through the timespan of a single generation if we seriously address the challenges and opportunities that face the evangelism of this generation of children.”

This document reads like a cynical action plan for a political/ideological group wishing to carry out a political/ideological change in society. And they are concentrating on our children because they see them as the group most easily captured or evangelised. And as a group which itself can further evangelise others.

When we send our children to public schools with a legally prescribed secular curriculum we do not expect they should be preyed on, evangelised, by such groups.

It’s time this was stopped.

Book review: The Atheist Camel Rants Again!: more arguments and observations from the atheist front by Bart Centre.

Price: US$10.71; NZ$20.60
Paperback: 326 pages
Publisher: CreateSpace (May 25, 2011)
Language: English
ISBN-10: 1460933915
ISBN-13: 978-1460933916

Personal passion does wonders for one’s writing. Mind you, passion is also polarising. Not everyone is going to love what you say, even though you say it forcefully and colourfully.

I am sure this is the case with Dromedary Hump’s latest book The Atheist Camel Rants Again! But that is part of what makes the book so good – for some of us at least.

The book is well named – it is a rant. But a colourful, humorous and soul-enhancing rant which will appeal to atheists and other free-thinkers. It was not meant to appeal to those who Centre satirically calls the “theologically deluded.” Nevertheless, I am sure there are some more open-minded religious people who will appreciate the humour and colour. In fact these people will probably find a lot they can identify with as they must sometimes despair at the stupidity reached by their more militant and strident co-religionists.

Like his earlier book, this one is a collection of 105 lively blog posts. They are each only about 2 pages long – which makes the book easy to dip into. You can read what you want, when you want, depending simply on what strikes your mood at the time.

In my review of his previous book (see The Atheist Camel Chronicles) I said that when Centre “calls a spade a spade” he “cleverly implies it might actually be a bloody big shovel.” Well he has lost none of that eloquence. Or humour. The satire and cynicism is just as biting.

Theist stupidity

Just as well, because there is still a lot of stupidity out there.  In “Pity the Persecuted Christians,” for example, he describes how some religious leaders:

“make it sound as though Christianity is undergoing a veritable Inquisition. . . .They cannot differentiate between their right to practice their religion (which is never implied) and the rights of non-Christians NOT to have Christian religion forced upon them . .  which is precisely what they are protesting. By impeding their holy charge to proselytize, convert, harass, badger, and impose their beliefs on others, it is they who are being persecuted. That’s about as bizarre a reversal of logic as one could conceive.”

Right on! Someone has to say it. People are fed up with the arrogant attitude demonstrated by non-consensual imposition of religious “values”, traditions and ceremonies. Centre colourfully describes this in “The Invocation:”

“the sky pilot couldn’t care less if it irks some because he sees it as his divinely directed duty to shove his God down people’s throats, welcome or not.”

In “Religion is a ‘Beautiful Thing,’” he asks:

“is it because religious charity is a way to proselytise to those desperately in need of material aid in an effort to gain converts? Is that the ‘beauty of religion’?”

Again, who else has wondered that?

And on a topical issue of marriage equality (“Those Damn Homos are Changing Word Definitions! Stop Them NOW!”) he tells opponents that “you’ll get used to gay marriage:”

“in five to ten years, gay marriage will be legal in a majority of states. And in three hundred to five hundred years, the Christian churches will apologise for their homophobic hysteria. It just takes them that long to catch up to humanity.”

And what about this depiction of a “Beffudled God” who requires a professional army of interpreters and apologists (in “Beffudled God: Good Thing he has so Many Interpreters”):

“Their God, it seems, is an articulate and confused old fool who has to rely on his creations to figure out and explain exactly what his words mean and policies should be. Liken it to a ninety-eight-year-old senile company founder who is kept locked in his office by the board of directors, and who translate his babble into whatever the board wants it to mean to the shareholders.”

Some atheists disappoint

But Centre doesn’t waste all his satire on the religiously inclined – some atheists also get a tongue lashing. He laments:

“a few atheists who, through their own stupidity, feed theist misconceptions of atheism. Some of them call for an ‘atheist church’ or at least see no conflict with the oxymoronic term. These atheists are the Uncle Toms, the embarrassing mentally impaired relatives of the activist atheist movement who are best confined to an attic or their parents’ basement.”

And later adds:

“On the other hand, if by calling every atheist organisation a church, mosque, synagogue, or coven we all get a major tax break . . .  count me in and call me ‘Reverend.’”

But, seriously, he is concerned about the knee jerk reactions of some atheists to current events:

“Perhaps my disappointment is my own fault, as I tend to credit freethinkers with using the same reasoned approach to all issues and events as when they rejected supernaturalism. More credit than we apparently deserve.”

Well, I often think we are not a rational species – even if we sometimes get some things right.

No one will be surprised to learn that Bart Centre is the creator and co-owner of the Eternal Earth-Bound Pets post-Rapture Pet rescue website (http://www.eternal-earthbound-pets.com/).

I started reading this book when I was feeling down. Before long I was laughing my head off. I had forgotten my own problems – except I was wishing I had such satirical skills.

If you are that way inclined, or even just open-minded and unafraid of satire, you will find this a book which you read through quickly. And then will start looking for his last one The Atheist Camel Chronicles.

But if you are sensitive about your beliefs (theist or non-theist) and can’t take a joke, then I recommend you avoid the book.

Infectious jubilation

Crowd in New York’s Times Square celebrate successful Mars landing – 1:30 am. Credit: Jason Major (@JPMajor)

The mass interest in the current Olympics, and yesterday’s landing of the Curiosity Rover on Mars really brought home to me that we are an empathetic species. We celebrate the achievements of others and feel the jubilation they do when things go right.

And with Curiosity’s successful landing I think we also celebrate the achievement because we see that it belongs to all of us. It is an achievement for all humanity.

The achievement is huge. The technically difficult landing seemed to go without a hitch. Scientists and engineers at NASA’s Jet Propulsion Laboratory were receiving images within minutes. Everyone was aware that attempts at Mars landing have a history of failure.

The descent by parachute was photographed by a high-resolution camera on board the Mars Reconnaissance Orbiter. – see below.

Photo: NASA – Curiosity Spotted on Parachute by Orbiter.

That seems incredibly lucky but clearly a lot of skill and technology went into this achievement as well. As Phil Plait wrote on Bad Astronomy:

“The simple and sheer amazingness of this picture cannot be overstated. Here we have a picture taken by a camera on board a space probe that’s been orbiting Mars for six years, reset and re-aimed by programmers hundreds of millions of kilometers away using math and science pioneered centuries ago, so that it could catch the fleeting view of another machine we humans flung across space, traveling hundreds of million of kilometers to another world at mind-bending speeds, only to gently – and perfectly – touch down on the surface mere minutes later.”

According to a media briefing earlier today the full version of this image also shows the abandoned heat shield which landed some distance from the Curiosity’s landing site.

Patience

Now we have to be patient while Curiosity is checked out by engineers and slowly brought into full functioning. It will be weeks before the vehicle starts driving around, sampling soil and rocks, and analysing samples.

Even the downloading of images already captured will take time. So far we are only seeing relatively low resolution images. Large teams of engineers and scientists will be working strange hours (the slightly different length of the Martian day (sol) and the Earth day causes “jet lag” for these people) receiving data, planning experiments, writing code and uplifting code and instructions.

Andrew Kessler gives an idea of the activity and life style of the teams involved in managing the last Mars lander – Phoenix – in his book Martian Summer: Robot Arms, Cowboy Spacemen, and My 90 Days with the Phoenix Mars Mission. For my review of this book see Working on Mars.

Curiosity requires patience

The Mars Science Laboratory, Curiosity, lands today – hopefully (5:31 pm NZ time). But when will we know if the landing has been successful?

Communication between Mars and Earth is hardly simple. It’s not just the time delays involved (currently about 15 min). There’s also rotation of both planets. So communication with Curiosity (if it lands successfully) will involve three satellites in orbit around Mars – the Odyssey Orbiter, the Reconnaissance Orbiter and ESA’s Mars Express. (Watch this video to see the alignment of Curiosity, Odyssey and Reconnaiscance during landing). Messages, and particularly data, may need to be stored on board Curiosity or the satellites before transmission to earth.

So we may not even have confirmation of Curiosity’s safe landing for several hours – maybe even several days. This video describes the problems and how they are overcome.

Thanks to Universe Today: When Will We Hear From Curiosity?

Curiosity’s landing site

Here’s a computer-generated view of Mars’ Gale crater as if seen from an aircraft north of the crater. Because of its history, 96-mile wide Gale Crater crater landing site is an ideal region for exploration of the planets history.

It has thick exposed sections of layered sedimentary rocks with a wet history. Joy Crisp, Mars Science Laboratory Deputy Project Scientist from NASA’s Jet Propulsion Laboratory said:

“The rock record preserved in those layers holds stories that are billions of years old — stories about whether, when, and for how long Mars might have been habitable.”

Going for gold – on Mars

I know Kiwi readers are going to have a hard time dragging themselves away from TV coverage of the London Olympics – and our current ranking in the medal tables – but it’s worth putting in an effort early Monday evening for the planned landing of Curiosity on Mars. This is scheduled for 5.31 pm New Zealand time – between the reruns of New Zealand Olympic triumphs on afternoon TV and live coverage of the new days activity in the evening.

There will be a number of sites streaming live coverage, but the NASA TV  is a safe bet. When I say live – it will be live coverage of the the scientists and engineers behind the attempt, and their reaction to incoming data. There is a camera on board the probe which will record video but that won’t arrive on earth for a few days. But those scientists and engineers are going to be pretty emotional – it will be a bit like one of those attempts at Olympic gold medals we have followed lately.

I imagine that space enthusiasts around the world will be organising their own parties and venues to follow coverage. NASA coverage will even be broadcast publicly in Times Square, New York. OK, landing is at 1:30 am local time – but they say New York is the city that never sleeps.

My earlier post Seven Minutes of Terror has a video showing the complexity of the landing operation. There is obviously a large chance of failure, because much of the landing technology is new. This will add  to the excitement and tension of the video coverage.  If successful, Curiosity will be largest rover yet to land on Mars. This image gives some idea of its size

Credit: NASA

It’s really a mobile laboratory and  will search for any evidence of past or present habitable environments in the Gale Crater area. Curiosity has mast-mounted instruments for surveying its surroundings and identifying potential sampling targets. Instruments on its robotic arm will enable close-up inspections. Sample of rock, soil and atmosphere will be analysed by instruments inside the rover. Even during its descent sensors on the heat shield will collect information on the atmosphere.

Curiosity’s initial planned programme provides for 1 year of investigations, and may be extended depending on funding and performance. It’s going to be fascinating to see what this rover discovers. Discovery of life, or potential habitats for life, or even evidence of past life will create wide interest. But even negative results will give valuable insight into the similarities and differences  between early Mars and early earth.

Let’s not forget that there is always a large team behind space probes and rovers like this. The photo below showing 2/3rds of the team behind Curiosity give some idea of its size.

And for those who love toys – Mattel Inc., who manufacture a die-cast line of Hot Wheels toy cars, is ready to release the car-size Curiosity as its latest 1:64 scale miniature in September. The Hot Wheels “Mars Rover Curiosity” set is part of Mattel’s assortment of 247 toy cars for 2012.

July ’12 – NZ blogs sitemeter ranking

Every month I get queries after posting these rankings. Some people are checking for mistakes. Others are wanting their own blog included. I am happy to respond to queries but have prepared a list of frequently asked questions (FAQs) people can check out. Have a look at NZ Blog Rankings FAQ.

Here are the rankings of New Zealand blogs with publicly available statistics for July 2012. Please note, the system is automatic and relies on blogs having sitemeters which allow public access to the stats. There are now over 270 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters.

I have listed the blogs in the table below, together with monthly visits and page view numbers for July, 2012.

Meanwhile I am still keen to hear of any other blogs with publicly available sitemeter or visitor stats that I have missed. Contact me if you know of any or wish help adding publicly available stats to your bog.

NZ Blog Rankings FAQ

It’s almost time for posting the July NZ Blog Rankings. Every month after posting a get a rash of queries about the list, and requests from bloggers for inclusion. So here as list of frequently asked questions which readers can consult.
Don’t hesitate to ask if your question is not covered.


1: What is the NZ Blog Rankings?

Produced monthly, usually on the first of the month,  it is a list of NZ blogs, ranked by their activity.

2: Why bother ranking NZ blogs?

Because some people see a need for it. Here are some possible reasons for this

  • Some will just use it as a list of NZ blogs with links they can investigate.
  • Others are more interested in the blog activity.
  • NZ bloggers themselves may be interested to see where they rank, and how well other blogs with a similar agenda, or speciality, rank.
  • Some bloggers may use the list as way of advertising their blog – a list of links attracting readers

There are no doubt other reasons, but the fact that bloggers want to be included, or bloggers and readers keep referring to the list indicates it has a use. Every month I notice a surge of activity by readers checking out the blog links on the list.

3: How are blogs ranked?

Several different ranking methods have been attempted in New Zealand. For example, using the Technorati or Alexa ranking systems.  Each have their adherents and critics. In the end I concluded that ranking using actual blog statistics is probably the most useful and objective method. Blogs are ranked by visit numbers for the month, and page view numbers are also included.

4: Why are many NZ blogs not included?

The statistics used in the blog rankings are obtained automatically and need participating blogs to include a site meter to gather the data and to allow automatic access to the data. Many bloggers already do this for their own information. But not all blogs have site meters, or allow public access.

5: How do I include my blog

Just contact me using the contact form below or in About me. Let me know your blog URL and the URL for your sitemeter (this isn’t necessary if you have installed a link or widget on your blog that I can find).

I am happy to answer queries about the process but suggest that bloggers at least attempt to install a suitable site meter before proceeding.

6: What site meter should I use

That’s up to you – providing I can automatically access the data. Ones that NZ bloggers currently use include  in order of decreasing popularity):

7: How do I allow public access to my stats?

A few meters allow public access by default. Sitemeter and Statcounter need setting the access to public. It pays to read the instruction for installation.

For Sitemeter:

Have a look at this article. The privacy level is set from the Manager section under the “Privacy Level” link. The default setting is NORMAL which allows public access by clicking on your counter.

For Statcounter:

Go to Config.>Control User Access and Public Stats.>Choose “All stats are public.

8: What about mistakes?

We all make mistakes – even with an automatic system. Contact me using the form below if you come across a mistake and I will attempt to fix it. Mistakes are most likely just after first inclusion in the ranking database.

9: Why do some blogs rank a lot lower than expected?

usually this is because the blog’s site meter has stopped recording and sometimes happens after a blogger has reformatted their blog. Eventually the numbers get really low and I check the blog. If the site meter has been removed I usually delete the blog from the list.

10: How do I exclude my blog?

I generally add NZ blogs with publicly available stats I come across. If you find you are included and you want to opt out just contact me and I will delete your blog from the database.

If you have another question or wish to include (or exclude) your blog on the ranking list  please use the contact form below:
