Evocative Endeavour

I did kind of wish for a second or two today, staring up at the big, black, underbelly of Space Shuttle Endeavour – boxed away at the California Science Center in Los Angeles – that I’d made more of an effort to see  she or her sisters performing live.

Am I getting all mushy and romantic about a spacecraft now?   Well, maybe just a bit.  My wife Erin said she felt unexpectedly moved after our visit.  I’d set myself to appreciative-engineer-mode before I went in, but still felt like I was standing on the rim of the Grand Canyon for the first time; you’ve seen all the postcards  and  videos, and can’t  imagine the real deal adding anything new – but  it does.  That’s  twice I’ve been emotionally sucked in by an iconic cliché.  Shocking.

Objects are evocative.  At one point I found myself back in my lab as a research student in Birmingham in 1986, hearing about the Challenger accident.  Then I’m back imagining all those tiles, engines, doors, and windows flying apart.

And there on Endeavour is that area of wing leading-edge, damaged on Columbia by falling debris during launch, causing her demise on re-entry in 2003 (more on that in this earlier post).

First Impressions

There is of course plenty of engineering to appreciate, and science behind it to ponder.  But my gut reaction is how big she is, the length of the cargo bay, and how….dirty .  It looks like she’s been treated like some science fiction fan might treat an Airfix model of the Millennium Falcon: roughed up, artificially distressed – so it looks like the real thing.  Except the distress, evidently manageable, is real.

Size perception is odd too.  I’ve seen video of the shuttle during ascent (in fact you can see it in Matt Mellis’s movie/iPad App called ‘Ascent’), where the ‘body flap’ – that piece below the engine in the picture below – is vibrating violently; it’s positively oscillating.  The flap looks small and flimsy on the film, but it’s a huge construction; the forces must be tremendous.

Tiles

The famous tiles, part of the Shuttle’s Thermal Protection System (TPS), are unmistakable.  Designed not to ablate like the heat shields on the Apollo capsules, tiles do suffer wear and damage, and some had clearly been replaced with new ones for display.

The complexity and variation of tile design is striking.  If you think tiling round the bathroom wash-basin is tricky, take a look at the area round the main engine gimbals and thrusters of the Shuttle.  No wonder maintenance costs were high.

Earthquake Protection

Several sliding bearings, or seismic isolators, sit between the Shuttle and its supporting pillars, insulating Endeavour from the perils of Los Angeles’ earthquakes.  The idea is the Shuttle rocks around harmlessly until the shaking ground settles down.

Visiting

We saw Endeavour in temporary accommodation; it’s destined to be mounted vertically in a custom-designed building.  That said, the exhibition as it stands doesn’t feel temporary, and the associated display areas and accompanying audio-visuals describing California’s particular role in the Shuttle story and showing off various artifacts from the program – including, importantly, the Shuttle’s WC or ‘space potty’, are excellent.

Entry to the California Science Center is free, but there’s a very reasonable $2 entry charge or ticket booking fee to see Endeavour.

Parting Impressions

I need a Tee-shirt, right?

Even as we celebrate, the Space Shuttle program is criticised, particularly around issues of cost and safety, but also the scope of its achievements.  As always, it’s easy to find fault in hindsight, and judge historical decisions by the political and economic expedients of the present day.  Personally, I reckon we’d be in a much sorrier state had the program not gone ahead.  The Shuttle was the workhorse behind the International Space Station, the full learning from which I suspect has yet to be converted.  And Endeavour personally, so to speak, enabled the repair of the Hubble Space Telescope.

NASA is at a turning point, collaborating more closely with private partners and, most recently, other nations on its manned space program.  While the arrival of new entrants, working methods, and relationships are culturally refreshing, surely much of the knowledge and expertise behind them has its roots in the Shuttle and related programs.

Hopefully this note’s been short and sweet.  There’s no point my repeating loads of technical and historical information you can get from many sources: not least the NASA and California Science Center websites, which, like Endeavour, are both worth a visit.

Puzzling over Tyrannosaurs at the Natural History Museum of Los Angeles

How when we dig up a dinosaur bone do we know it comes from a young animal or a smaller example of a different species?  That’s a question the Museum of Natural History of Los Angeles collection of T.rex helps answer.

Yesterday, Erin and I visited the new Dinosaur Hall, where for the first time fossilised skeletons of three complete Tyrannosaurs are brought together to illustrate the different stages in the animal’s development.

Above you see the three who died at 17 yrs, 14 yrs, and 2 yrs.

Here’s the largest, Thomas, as he looked a couple of years back when we last visited the museum: encrusted in rock, but the star all the same of his own very public extraction in the Dino Lab:

At 14 yrs. Adolescent, but dangerous.

On a lighter note.  Ever wondered what a Tyrannosaurus rex looks like with (most of) its bones missing?  Probably not I guess, but here it is:

Boneless

This was a bit of fun we got roped into: a Tyrannosaur puzzle no less.   The bones of the T.rex are taken off the frame, and it’s up to us non-experts to put them back in the right place.   It’s harder than you might think – and it makes you think! (Shh – that’s the point).

Where to start…..

I got off to an easy start with those deceptively unimpressive fore-limbs we all know and love from Jurassic Park, but soon came to grief when it came to the ribs. Best leave things to the experts:

The tail bone’s connected to the …..er…..?

Assembling a Tyrannosaur is just like working on your car: there’s always an extra piece left over when you put it back together……

Great exhibition and well recommended.   Thanks to NHMLA for an enjoyable afternoon.

 

Annular Solar Eclipse 20th May 2012

Eclipse near maximum projected from 100mm Swarovski spotting scope

I’m in Los Angeles at the moment, which means I got a half decent view of this evening’s annular solar eclipse.

The sun didn’t show as a true annulus from where I am, but an off-set 85% coverage is pretty spectacular all the same.  The sun’s image is projected with a 100mm spotting scope, and I took pictures with my standard camera.

With projection, you need something to shade the image from the direct light of the sun, and failing anything better at hand, I find my head does the job – complete with muzzed up solar flare haircut for the occasion!

Note, this is all about projecting the sun’s image.   Remember: NEVER  LOOK DIRECTLY AT THE SUN THROUGH A TELESCOPE.

The eclipse started at 17:24 PST and reached maximum at 18:38 PST.  I caught the maximum but gave up shortly after because of trees getting into the shot.

Working backwards from maximum eclipse, this is at 18:39.

Few sunspots visible again near maximum eclipse:

About half an hour before maximum…

18:10 PST. About half an hour to maximum eclipse

Sunspots come out very well in projection.  There’s some distortion of the shape of the sun/moon by this method, because the camera is always a bit off-centre, but I reckon the detail is pretty good.

Well on it’s way….

30 minutes or so in....

Craters on the moon?  For sure there are craters on the moon.  But can you see them in profile during an eclipse?  The air tends to ‘boil’ the image so much that it’s hard to separate out random optical effects from real lunar geography.  These two shots were taken a few seconds apart, so features appearing on both are likely to be real.

Close up showing surface irregularity of moon

Same as above but a few seconds later:

Close-up showing surface irregularities of moon (as above plus a few seconds)

I think there is a bit of a dip about a third of a way up the limb, but it’s not clear cut.  To do this properly, we’d need to take a bunch of photographs and electronically combine them to get an average profile over a few seconds or minutes.  Some dedicated soul out there will have done it.

Zoonomian Podcast – Interview with Alan Mootnick, Director Gibbon Conservation Center, Santa Clarita, California

Alan Mootnick

(Update 4th November 2011.  We were very sorry to hear of Alan’s death earlier today.  A fantastic guy and unmatched friend of gibbons.  Rest in peace Alan.)

What better way to spend Christmas than in the company of your favourite gibbons?   That’s exactly what my wife Erin and I did on the 26th December 2008, on our second visit to the Gibbon Conservation Center at Santa Clarita, California – home to some of the world’s rarest gibbons.

As well as catching up with gibbon families first met in September and described in this earlier post, I recorded the gibbons singing, and an extended interview with the Founder and Director of the Center, Alan Mootnick.

Much of what Alan has to say about working in gibbon conservation with various institutes, authorities, and peoples around the world, and particularly in Asia, is also relevant to other species.

Part 3 – Breeding Program

Alan describes the breeding program for the Javan gibbon – of which only 4000 remain in the wild, the Center’s collaboration with zoos – including in the UK, and the challenges of finding gibbons for study in the wild.

 

Part 4 – Taxonomy

Gibbon genomics, taxonomy, and a showcase of mistaken identity.  The challenges of moving gibbons and their DNA around the world, and the role  of faeces in working out bloodlines.

Part 5 – Behaviour

Including apparent similarities with man, and discussion around gibbon song and brachiation (swinging arm to arm).  The highlight is Alan’s empirically supported theory of hostile genital or anal presenting – ‘gibbon mooning’ in other words.

Part 6 – Volunteer Program

Including the possibility of joining the Center from the UK.

Part 7 – Threats

Discusses issues around land management and deforestation in Indonesia, the illegal trade in gibbons, and the impact that’s having on the gibbon population.  Also some tips on how to work to best effect when dealing with zoos in Asia.

And this is the entire interview as a single edit:

Interview With Alan Mootnick – Director, Gibbon Conservation Center, Santa Clarita

(Update 4th November 2011.  We were very sorry to hear of Alan’s death earlier today.  A fantastic guy and unmatched friend of gibbons.  Rest in peace Alan.)

What better way to spend Christmas than in the company of your favourite gibbons?   That’s exactly what my wife Erin and I did on the 26th December 2008, when we made our second visit to the Gibbon Conservation Center at Santa Clarita, California – home to some of the world’s rarest gibbons.

As well as catching up with gibbon families we first encountered in September, and described in this earlier post,  I made some sound recordings during this visit, including an extended interview with the Founder and Director of the Center, Alan Mootnick.

I hope you’ll  find the resulting podcast, which you can stream or download below, gives an in-depth, candid, yet often humorous insight  into the mission of the Gibbon Center, the plight of the gibbon, and the work of a dedicated scientist and hands-on conservationist.

Gibbon Half A Chance

Last month, the International Primatological Society reported that nearly 50% of the world’s 634 primate species and subspecies are in danger of going extinct, with more than 70% of species in Asia coming under near term threat. Reading this on the way out to the USA earlier this month set a grim backdrop to an encounter I had very much been looking forward to.

Gibbons are found in three places: the jungles of Asia, the zoo, and, the subject of this post – a gibbon conservation center.

It was with bleary eyes that Erin and I arrived at the Gibbon Conservation Center in Santa Clarita, California, at the virtuous hour of 7.15 a.m. Erin had arranged the visit with Director and founder Alan Mootnick, as an anniversary present (I am a lifelong fan of these hairy cousins). Not an all-comers zoo, the Gibbon Center welcomes groups and serious researchers by appointment, so the personal tour was a bonus; a little politeness and a sensible donation helps.

The declared mission of the Center, established in 1977, is to help ensure the survival, preservation, and propagation of all gibbon species in the wild and captivity, to provide a captive haven for gibbons as a complement to protecting them in the wild, to educate the public and to further our knowledge of gibbon care, and to support ongoing field projects.

Alan warmly welcomed us at the gate and introduced our feet to a tray of disinfectant. Gibbons are highly susceptible to human disease and, with forty in residence, precautions are essential. It is unsettling to learn that more than 75% of Americans have oral herpes but downright scary that the gibbons who contract it will be dead within four days. Volunteers are the lifeblood of this Center, but medical tests are a pre-qualification.

The wire fenced compound houses several individual cages of gibbon family units – typically a male, a female, and one or two offspring. The family theme is very strong and not artificial – this is how gibbons live. One group we became absorbed with comprised a darker haired, white-bewhiskered male, a golden female partner nursing a gangly infant of 1yr, a hyperactive younger son, and an older sister – visible to, but separated from, the group; the consequence of uncontrollable spats at meal times. Anthropomorphising animal behaviour may not be in vogue or politically correct with some, but after three hours close to these families the parallels in behaviour to our own are obvious – whether we like it or not.

A successful breeding programme is essential to meet the Center’s conservation goals, and there was evidence aplenty of this during our visit. Between the five families on which we focused, we saw three recent offspring (including the acrobatic ‘Canter’ in the photo above) and two evident pregnancies. Such prolific reproduction is one indicator that the animals are relatively happy in their captivity. Also, while the chainlink fencing looks intimidating to us, its regular geometry and strength makes it popular with the gibbons, who strangely have spurned more sophisticated apparatus provided for their brachiating delight (that is their characteristic swinging from arm to arm). We certainly saw no evidence of the repetitive and obsessive rocking behaviours characteristic of bored, disturbed or mistreated animals. With no less than nine separate feedings a day, there is little chance of gibbon ennuie setting in within this community.

While Mootnick clearly cares deeply about his charges, he is not overly sanctimonious in pursuing his task. He delights in the gibbon’s hesitant yet rapid two legged walk, likening it to a man walking on hot coals. Indeed, the gibbons’ entertainment value may be their salvation; during the tour a call came in from a major TV company keen to film at the Center, and its not the first time, as this sequence for the L.A. Times and this half-hour interview with Alan Mootnick shows.

Inevitably, the conservation business has its own politics. The main players are zoos providing a more corporate approach; then the ‘activists’ – who seem driven mostly by the principle of keeping gibbons in their countries of origin; then groups like Alan’s (his model is not unique) – which, while a team effort, is also personally inspired with a flexibility that I sensed is not always endearing to more regimented interests. But from the recent visits and best practice exchanges that Alan described – not to mention gibbon exchanges – the Center is an important part of an informal network that essentially pulls together. 2% of donations to the Center go to support projects devoted to conservation of wild gibbons.

Despite the Center’s success, encroaching humanity from an enlarging Santa Clarita is threatening the gibbons and driving the current imperative and funding appeal to relocate and expand operations. Details are on the Centre’s website.

I will be following the fortunes of these California residents with interest, and plan to call in at the Center again over the new year. In the meantime, I would encourage anyone to learn more about the plight of primates, and especially gibbons, and consider supporting the Gibbon Center if you are able.
