What Happened After [leaving H.E.S.S.]

Etosha National Park13/10/11 - 15/10/11

After a handful of nights sampling the various Backpackers of Windhoek, I boarded a Northbound-soon-to-be-Southbound overland truck headed for the first stop of the Acacia Cape Desert Safari – and brought its number up to a baker’s dozen. Miles upon miles with naught but giant termite mounds to look upon hardly readied the pallet for the feasting of our eyes on the many wonderful animals of Etosha National Park. Over the course of two days’ game drives I saw pretty much the entire cast of I Just Can’t Wait to be King. There were all manner of antelope (including a few old faces from the farm), and birds of every shape and size and colour. We camped at Okaukeujo, beside a floodlit waterhole; a more intimate viewing platform than the truck, and this is where I saw my first lion – an experience not in the least marred even by the DEET fumes rising from every square inch of my exposed skin. My chief fear in the tent both nights was that the (potentially rabid; free-to-roam-the-camp) jackals might like the smell of the Vicks VapoRub on my chest. I feel incredibly blessed to have been an observer here – watching the African wildlife in its natural environment is an experience I struggle now to capture with just words and pictures. Life crowds the waterholes and the shade. I saw elephants bathing, Oryx rutting, ostriches with wings outstretched to shield their chicks from the sun. I saw a “real” Zebra crossing! After Etosha, The Lion King would never be the same movie to me again.


My first lion sighting - taking a drink at the flood-lit waterhole by Okaukeujo!

Spitzkoppe15/10/11

Upon leaving Etosha, we strayed off the tour-schedule-path somewhat in paying a visit to a nearby cheetah farm, where we fed the resident cats their… I suppose it must’ve been brunchtime meal! Kudu-on-a-stick. To interact with these beautiful animals was a real highlight for me, and carried a wave of nostalgia and sentimentality as I compared the deed with keeping my own fine felines at home in Felix and treats!  Afterwards, we made for Damaraland to spend the night at a bush camp by the Spitzkoppe [bush camp noun a camp with no running water, in which you might get rained on whilst spending a penny], which had a definite Pride Rock thing going on. Nestled at the foot of the bornhardts, we toasted marshmallows over the fire and slept out under the moon and stars, specifically (in my case) under a work-of-engineering involving two brooms, a mop and a mosquito net. My heart still racing from the scaling of one particular monadnock during a hike earlier that afternoon, and after Riann dropped a beetle onto my laptop with a cry of “There’s a bug on your computer!”, I wasn’t about to let a single wayward insect disturb my peace. The place was at once eerie and beautiful by night – almost as I imagine the haunted Dwimorberg of Middle Earth, and I treasured its remoteness.


Well-fed Cheetahs!
Our shadows at Spitzkoppe!











Swakopmund16/10/11 - 18/10/11

The Skeleton Coast.

Remember the Nothing described in The NeverEnding Story? Well on our journey to the seaside resort of Swakopmund, I almost believed we’d found it! What it was, in actual fact, was a bank of ocean/desert fog, the breach of which turned our surroundings into a lunar landscape. It was cold, quiet and bleak, and the sight of shipwrecks as we neared the South Atlantic only made things spookier! We had reached the Skeleton Coast. Further South, Swakopmund slowly stole its way into our sights with its colonial German architecture and dusty, palm-lined roads. Here we tasted 48 hours of civilisation – restaurant dining, free Wi-Fi, an en suite dorm with four walls and a ceiling! I even saw my first domestic cat in five weeks. And in the interest of purchasing souvenirs for kith and kin, I tried my hand at haggling! My attempts then and later were not nearly so dismal as Python-Brian's, which I might easily have misguidedly emulated. In fact I drove a hard bargain, though I did so by playing the pity card. …But if it works, it works, right? Inspired by the most stunning alcohol packaging I’d ever laid eyes upon, I also bought myself a take-home bottle of Wild Africa Cream liqueur. It had a furry, leopard-print jumper on. Need I say more? You can even like this on Facebook!

The Desert18/10/11 - 19/10/11

In the Namib desert.

From Swakopmund, we continued South through the Namib Desert, skirting the edge of the Naukluft National Park, which was significantly more burnt in appearance than I remembered from my nearly-end-of-shift-day-trip. There had been smoke on the horizon that day though… I came over all nostalgic at the sight of the Gamsberg (as constant a companion during my stay at the farm as the telescopes were, albeit not so close at hand!), and upon re-crossing the Tropic of Capricorn in the opposite direction. We stopped before lunch for a bushman safari, on which we learned how a trapdoor spider keeps his house and secures his meals, how the local flora cope with the limited water supply, and what becomes of a mountain zebra after a run-in with a leopard. (In a grisly case of Here’s One I Made Earlier, we could also make an educated guess as to the fate of its uneaten calves, seeing as the patio table back at base had stripy, black-and-white legs, the likes of which you wouldn’t find even in IKEA!) We met the first, second and third of many dung beetles there, presumably enjoying the shade cast by our truck. 

A trapdoor spider's trapdoor!
I revisited the German bakery at Solitaire, this time sharing carrot cake with the finches instead of apple strudel, which along with the resident peacock and peahen invoked fresh home-sickness in reminding me of dear Bradgate Park. (Note to self: well resisted on the pun there, Kate!) We made camp in Sesriem, having explored the canyon on its outskirts, which was to my mind a miniature Samaria Gorge – right down to the little stone pyramids certain of our number made use of for stone-throwing practise! Not to belittle their attempts (why, they were as good as any hobbit’s!), but I can’t say I would wish a similar doom upon the structure mum and I created all those years ago in Crete. A windbreaker fashioned from spare mattresses kept the chill off that night, until at truly-ridiculous o’clock we left to climb Dune 45 at Sossusvlei and watch the sunrise from atop it! A breath-taking, humbling sight, almost worth the terrifying ascent preceding it. What with H.E.S.S. I saw a fair few sunrises in Namibia, but this was the most spectacular. There was almost a Nants ingonyama bagithi Baba! on my lips! We broke our fast on solid ground, after emptying the sand from our trainers (creating our very own mini-dunes in the process.) We were not done with sand for the day, however – for there was still Deadvlei to explore! [lit. “dead marsh” …but I met no Gollum here.] We (that is, Debbie and I) hiked as far as the entrance sign and back (given our 90-minute time allowance) undeniably traversing bona fide desert – it was hard going even with such luxuries as water, sunscreen and other-people’s-footprints-to-walk-in: a vast, unforgiving landscape. By evening (near the village of Bethanie), my hair was grey with sand and dust.

Fish River Canyon 20/10/11
  
At last a change of terrain as the tour took us yet further South to Fish River Canyon – the second largest canyon in the world! We occupied our time with the throwing of stones and the making of echoes and the taking of photos (even a foot’s-eye-view of the gorge!). The camp for that night – Ai-Ais – was in the valley itself, and I spent the last of my Namibian dollars relaxing in the hot-springs-heated indoor pools: I felt halfway between a lobster and Harry-Potter-in-the-Prefects’-bathroom.

South Africa21/10/11 - 26/10/11

A view of Table Mountain from Cape Town
And so we bid farewell to Namibia – I after over five weeks of calling it home. By noon we had crossed over the border (domestic cat #2 was patrolling it) into South Africa, and begun preparations for a “Christmas” celebration on the banks of the Orange River. That afternoon saw us swimming in it – back to Namibia in fact, technically. Sand- and stick-smuggling aside, with the exception of the (wee) Lin, I don’t think I’d so much as dipped a toe into a river before, so the experience was quite exhilarating. We weren’t caught in our illegality. By nightfall, singing fairy lights had been draped about a convenient tree, and there was punch to drink and secret-Santa gifts to distribute! It was a carefree, click-happy night that ended with an outdoor screening of The Lion King. I fell asleep trying desperately not to think about the dead baboon spider we’d spotted in the bar; whether it had any living relatives thereabouts! Our final night was spent beside a vineyard, and for the third and last time – in tents! This because of the rainfall, which like any self-respecting and instinctive Brit, I foresaw after one look at the clouds. I shared my morning shower with a gecko, and we both enjoyed a beautiful view of the valley below through the window-cum-hole-in-the-wall. The last leg of the trip took us to Cape Town, where we were taken on a township tour of Langa – an eye-opener and no mistake. I had my first taste of maize, somewhat sullied as new culinary experiences go, by my fully expecting mash potato! Later, as the truck drove away, leaving us at a Backpackers in Green Point, my time became my own again – and I had three days to play with before the flight home! One of these I spent touring the Cape Peninsular. I hopped on a boat bound for Seal Island from nearby Hout Bay. There, and in the choppy waters, were a multitude of (you’ll never guess) seals. I visited Simon’s Town to see the penguin colony on Boulders Beach, and from there biked 7km down the road with my nose full of Springtime blossom and the sea. Next stop one of the Cape Point lighthouses – via Funicular – and thereafter a hike along the cliff to the Cape of Good Hope (for the obligatory photograph). 

die Kaap van Goeie Hoop

Drinks that night with remaining tour-buddies at Cape Town’s Long Street Café, and dinner (in a cauldron!) at “Mamma’s Africa”, with live music I can only describe as a kind of African opera! Brilliant. My remaining time in Africa dispensed with Science and Adventure in favour of souvenir shopping. More bartering at the market in town, and postcard-buying on the V&A Waterfront. At last the following evening, I left the Southern Hemisphere behind me, and after eleven hours of cat-napping, landed in London (just like the song!) It was raining. Glorious. The view from the coach window as I sped toward Leicester swapped quiver trees and pencil trees for rain-drenched countryside; fairy rings for wind turbines. Such beautiful greens and greys. My homecoming was all I had envisioned; my reunions (parent, sibling and feline alike) a little like the tear-jerking scene from Homeward Bound – but I would go again.

In no particular order…
(New) animals encountered since last post: Lions, cheetahs, jackass penguins, elephants, giraffes, plains and mountain zebra, red hartebeest, kudu, secretary birds, black-faced impala, kori bustards, black rhinoceros, ground squirrels, guinea fowl, wildebeest, bontebok, peacocks, vultures, pale chanting goshawk

(New) animals eaten since last post*: Ostrich, Springbok, Kudu stew!
*…none of them tasted half so good as Oryx though!

The “Big Five” Highlights:
Etosha, feeding the cheetahs, sunrise from Dune 45, swimming in the Gariep, working for H.E.S.S.

Please note, the photos here are ~2% of what my camera captured, so if a picture can tell a thousand words, you’ve not heard the whole story. I refer you to The Lion, the Witch and the High Energy Stereoscopic System on my Facebook page!

It’s like Twoflower said: “You see, last night it occurred to me, I thought, well, the thing is, all this travelling and seeing things is fine but there’s also a lot of fun to be had from having been. You know, sticking all your pictures in a book and remembering things…  The important thing about having lots of things to remember is that you’ve got to go somewhere afterwards where you can remember them, you see? You’ve got to stop. You haven’t really been anywhere until you’ve got back home.” – The Light Fantastic

As to the end of my adventure, the Road goes ever on and on – does it not?

Goodbye from Goldilocks

As of the morrow I cease to be in Namibia as a seconded scientist to the H.E.S.S. project and instead begin the business of closing up for Christmas sight-seeing! Part of me will dearly miss the nightly routine that goes something like: wake up at some ungodly hour; battle with the cameras until they’re persuaded to work; open the roofs of the camera huts (with brute force and a pole in the case of CT2!); find the way back through the gloom to the Control Room; park out the telescopes; cross fingers for a smooth shift! The part of me that rather enjoys sleeping at night-time couldn’t be happier. I’ll be honest. The image of myself – the shifter – trekking from telescope to telescope of a night with nothing but my headlamp and the vaguest sense of where I’m going; animal cries and the hum of insects in my ears, would not look out of place in a horror film. With this in mind, I think I’ve rallied pretty well all told!
~~~~~~~~~~~   A Sciencey Interlude  ~~~~~~~~~~~

The question of how the H.E.S.S. telescopes actually detect those precious gamma-rays has been put to me a few times since I came out here, so I thought I’d spend a few words in addressing it. Feel free to skip this section if you’re not in the mood for an Astrophysics lesson. Feel free to hum the Monty Python Intermission theme whilst you read.

As you’re probably aware, the Earth’s atmosphere shields us from cosmic gamma radiation (which is just as well!) but incident very-high-energy photons do generate a signature electromagnetic cascade of electrons, positrons and secondary photons, when they interact at high altitude. The particles in this shower are super-relativistic, and as such emit Cherenkov radiation. These nanoseconds-long flashes of blue-green light can be detected – in stereo – using the four H.E.S.S. telescopes, provided both the sun and moon are below the horizon and assuming the light pool favourably covers CT1 through 4. The images recorded by each camera allow the position on the sky of the parent γ ray to be reconstructed, and the image intensity gives us its energy! Magic, no? (Not to be confused with MAGIC – a Cherenkov telescope on the Canary Island of La Palma)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So today I take my leave of Ferdi, Jade, Jenny and Clia (the actual names of the cameras, you understand, and nothing to do with my fancy). I have braved the cobweb-ridden huts for the last time and can marvel at the construction of CT5 (alternately nicknamed The Monster and Daddy Bear depending on my mood) no longer. In the last month I’ve been involved in real SCIENCE, but I’ve also hiked out to look at cave paintings, visited a German bakery in the desert, and read three classics (like a good girl) on mum’s Kindle. (These were Wives and Daughters, Pride and Prejudice and David Copperfield – you can check out my Goodreads page to see what I thought of them!) It has been a full and fulfilling experience, but I think I’m quite ready for a change of scene – and indeed, a change of genre. So next on the reading list is the real “There and Back Again”, and the PDF version of Machine of Death stored on my laptop, and then – after a fortnight or so – I can be reunited with paper-and-ink books, of which I miss the look and feel and smell! The “m” word is such a can of worms these days…

I miss my morning cup of Earl Grey with milk and half a sugar. I miss counting the rabbits outside Syston Train Station on the way to work. I miss swinging my brolly round my wrist when it’s not-raining-but-might-yet-rain. I miss standing my origami T-rex and Parasaurolophus back up when they are knocked down. I miss quoting A Christmas Carol/Will Hay/The Ghost & Mrs. Muir with mum at every opportunity. I miss driving to Loughborough with my latest playlist on shuffle. I miss fish and chips and mushy peas from Birstall Fisheries. I miss waiting outside the pub for Loo and Sarah; wondering how many songs it will take them to arrive. I miss Baileys and milk. I miss Orion being the right-way-up.

Daddy Bear, Mummy Bear and Baby Bear (CT5, 1 and 3)

Animal encounters since my last post: a jackal, donkeys, camels, squirrels, rabbits, canis lupus familiaris (specifically some very friendly terriers!) and more oryxes, springbok, ostriches and wild horses. And birds. So many birds. I’ve seen more birds than people this month.

So it's goodbye from me, H.E.S.S.

Gecko in the Garden

Be welcome to another account of life in OPPOSITE WORLD, where Autumn is Spring, night is day and taps and locks respectively loosen and open the wrong way, blast-it-all! I am become nocturnal, waking a few hours before the long moonless shifts begin, and returning to bed before the sun is up. The lightproof shutters in my room go a long way towards fooling my body into sleep, where at least I can dream of daylight (that, and cannons-fired; “arcade vampires” in underground, watery caverns; rooftop journeys ‘tween London Town and Leicester, and Big Cats loose in my house, apparently!)

I’ve a somewhat gloomy countenance this week, for the Science has given way to cloud overhead, and the rise in humidity has sent the creepy-crawly count through the roof! I don’t know that you remember the Animal Ark series of Children’s books, with their quaint, alliterative titles, but here my mind dwells querulously on such imaginings as Spider in the Sink and Hornet in the (telescope) Hut… I jest only to hide my (very real, if irrational) fear of such beasties.

Geckos now, may be said to creep and to crawl, but are a whole different kettle of fish! I have such an affinity for the little dears, being I think the most draconic and endearing of reptiles alive today. One of the characters in my book is a gecko in fact, and her likeness is painted on the front of my ukulele. Of themselves by all accounts, they are such charming creatures, and a night or so ago, upon finishing the shift and making for bed, I learned a shocking lesson about them. I spotted something white writhing on the ground like a fish out of water, and immediately jumped to the worst conclusion – that this was some hellishly large and poisonous invertebrate – when in actuality a gecko had been spooked into dropping its tail. This is a remarkable defence mechanism of theirs, and all my dread-turned-horrified-concern dissolved upon hearing that they are then able to grow a new tail. This I was assured of before I could peaceably go to sleep!

One wonder (if indeed it can be called so) I’ve witnessed since these long shifts under cover of cloud began, is that of absolute darkness – the like of which can only be "seen" in the strict absence of light pollution and starlight. It is akin to blindness, and really quite disconcerting, disturbed yesternight by lightning; this morning (in the wee hours) by the storm-induced bushfire on the horizon! I can only liken this alarming sight to the scene from The Two Towers in which the hobbits have their first glimpse of far-off Mordor.

Here follows a few things I find myself missing...
             
Grass You may laugh, but last week we drove into Windhoek to buy some groceries, and I was briefly at liberty to explore a little hotel courtyard, where I was so delighted by the sight of grass I immediately had to sit myself thereupon and feel the blades between my eager fingers!

Rain There was lightning to the East even as I wrote this item, followed by a downpour-of-sorts, but this fortnight past has elsewise been dry as a bone, and the rain here doesn’t smell half so good as it does back home. 

The cats I shouldn’t wonder you think this unfeeling, when I’ve not confessed first to missing my family and friends (who of course I do!), but I’m dealing more in specifics here, and I long for a glimpse of Gump’s wonderfully expressive face; the sound of her plaintive meow, and Cully’s soft purring response to my goodnight scratch-under-the-chin. Yes – even Monty’s sandpaper tongue!

Carpet It gets sillier I know, but there’s something very clinical and uncomfortable about floor-to-floor tiles!

Gotta Catch 'em All


It is here in the Khomas highlands of Namibia – on the site of the High Energy Stereoscopic System – that my adventure begins. The shifters’ residence building was a welcome sight indeed after my 27 hour-long journey, made sweeter still by the discovery of an acoustic guitar in the sitting room, and my learning that the nest above my bedroom door is in fact home to a swallow, and not some hostile insect intent upon bleeding me dry. The abrupt change in season and altitude have had no truly adverse effects as yet, though I noticed those extra 1600 metres when I took a short bike ride on Monday, and had the winds knocked out of me. Meal times are largely a carnivorous affair (Gemsbok barbecue, anyone? My first taste of game, I rather think!) and taken outside, with the Gamsberg (Namibia’s table mountain) in sight upon the horizon and the tweeting of myriad little birds on the air.

Of course my situation this month is by no means perfect. I am the only individual on site lacking a Y chromosome, the dry air is wreaking havoc on my skin, and a good 50% of the flora and fauna pose some threat or other if I get too close, but you know, I think it’s worth it just to see the Milky Way painted gloriously across the Southern night sky of an evening, or watch the telescopes slowly parking out in unison before a shift; to witness finally the rising of the Magellanic Clouds (Big Fuzz and Little Fuzz as I've come to name them) or play spot-the-γ in the Control Room as events flash onto the monitor in real time. It’s all really quite magical.

So today I met a singing; dancing warthog who assured me in a rich baritone (in no uncertain terms) that I should adopt a problem-free philosophy from now on.
Okay, that’s not altogether true. Would that it were! I did see a warthog at the side of the road, seemingly fully occupied with grazing for it paid us little heed. I’ve seen such animal life here I hardly know where to begin! Birds of prey, Oryxes and Ostriches, Snakes and Springbok – and baboons in abundance! Nearby waterholes make such sightings frequent, and this will tide me over ‘till the safari next month.

In case you’re wondering, the title of this post alludes at once to the obvious plight of the gamma-ray astronomer, and my completing the set of naked-eye-planets-viewed-through-a-telescope at long last – with Jupiter rising even before the Witching Hour and the use of a sturdy little optical reflector living on site, I was treated to a wondrous view of the great gas giant that has eluded me for so long! Its zones and belts, and four of its satellites were also visible, and Sky View Café assures me these were Io, Callisto, Europa and Ganymede. Incidentally, Pokémon with planets rather than pocket monsters would I think be a far easier state of affairs, given there are only eight of them (sorry Pluto dearest – your ship has sailed).

So without further ado, a gamma-ray haiku, entitled Monitor Number Five:

Gamma rays, these days
Are little fishes swimming
In Cosmic-ray pools

Muons are ripples
On the detector surface
From Cosmic-ray rain

The fishes converge
On a night-sky point: Here be
Cosmic-ray dragons

Still alive and there's Science to do!
