Back to basics for US

A private space company attempting to make history today by firing its Dragon space capsule into orbit en route to a rendezvous with International Space Station had its launch aborted in the final seconds of liftoff.

The launch of the Falcon 9 and Dragon has been strictly downplayed as a ‘test flight’ by SpaceX officials and NASA observers. But a lot rests on its successful outcome which could buoy or blunt future political support for a private US space race in human spaceflight.

A year ago the iconic buildings and launch pads at Kennedy Space Center, Florida, were still a hive of activity and excitement as NASA and the US remained enraptured by the final launches of the Space Shuttle programme.

This morning’s dawn launch preparations took place far away on a dedicated launch pad and SpaceX preparation area at Cape Canaveral Air Force Station. A new launch attempt is now likely to be made on Tuesday.

I visited the SpaceX site last summer when the company was keen to show off its facilities and give us a close up view of the launch pad as it was preparing for an end of the year Falcon 9 launch.

If fully successful, this new mission will be a big confidence boost for SpaceX and NASA, which are partners for at least 12 unmanned cargo delivery flights to the Space Station over the next few years.

It will also edge the US a little closer to regaining its ability to launch humans into space - a capability it had maintained for five decades until the final launch of the Space Shuttle last summer.

NASA has paid SpaceX $381 million in an agreement to help pay for the design, development, and testing of the Falcon 9 rocket and Dragon spacecraft. SpaceX has spent $1.2 billion to date, including public and private capital.

NASA and SpaceX are also jointly funding the design of a crewed version of the Dragon spacecraft to transport astronauts to the Space Station later this decade.

But SpaceX still has to compete with other aerospace companies for further NASA financing to support development of rockets and spacecraft for human occupants.

"We know this has been touted as a huge mission," said Gwynne Shotwell, SpaceX's president. "We keep trying to say it's a test. Nonetheless, it's a big job. Success is not going to mean success of the commercial space industry, and failure is not going to mean failure of the commercial space industry."

Shotwell told a press conference at KSC the day before the flight that the most important outcome of the Dragon test flight was to learn from it - as the spacecraft's solar arrays, navigation and rendezvous sensors, and flight computer were all new.

Politically the flight comes at a crucial juncture just as budget decisions are about to be made in Washington.

Success will prove it is possible for SpaceX and other commercial operators to do the work NASA has advanced since the 1960s.

The mission is crucial for International Space Station operations. Assuming all goes well, SpaceX intends to launch its first, fully loaded cargo resupply mission to the station in mid-August.

Another company - Orbital Sciences Corp - has a $1.9 billion contract to launch its Antares rocket and Cygnus spacecraft on eight cargo missions.

Orbital plans to launch a test flight of its Antares rocket in July. Then in September, an Antares rocket is scheduled to launch a Cygnus cargo carrier on a demonstration mission before its first cargo resupply mission to the Space Station in early 2013.

With the US pace Shuttle fleet firmly retired, the Dragon is the only means to return scientific experiments and equipment from the Space Station. All other robotic cargo carriers servicing the orbiting outpost double as rubbish trucks and burn up in the atmosphere.

"Since we no longer fly shuttles, we can’t take anything sizeable back down from the Space Station and this is absolutely critical to Space Station," Bill Gerstenmaier, associate administrator for Human Exploration and Operations, said.

The commercial space race in the US may be hotting up but it can’t disguise the fact that the country and NASA will remain without the ability to put people into orbit for at least another five years or perhaps longer.

Postcard from Namche Bazaar

We’re on our way down. Arrived at Namche Bazaar mid-afternoon and able to post an email to guys back home from the local internet café.

The lower altitude means our bodies are alive with the 'extra' oxygen - an exhilarating feeling. But this has been a challenging journey for us normally office-bound mortals.

There have been times of great beauty and times of intense physical effort. We have gazed upon golden eagles from above as they swoop and soar below.

There has been a helicopter evacuation of our youngest member after he fell seriously ill with altitude sickness.

And we have experienced extreme cold and biting winds when it seemed almost impossible to keep warm.

Now we are on our way home. It has been a life-changing experience, a test of stamina and willpower, and all in the presence of the world's mightiest mountains.

Unforgiving and at the same time alluring in their pristine and rugged beauty. To see snow billowing from the mountain tops in the early morning jet-stream set against the clearest and deepest blue you could imagine is a sight to behold.

To trudge through a glacier that has created a landscape so alien it seems like no place on earth was both exciting and scary at the same time.

And always we have been supported by our able team of Sherpas, porters and cooks, whose cheery demeanour and willingness to serve is a lesson to us all.

They have guided and met our every need. Sometimes cajoling us along a particularly awkward path or offering to carry a rucksack when the altitude bites at our lungs and demands more than we are seemingly able to give.

We have climbed to more than 5,000 metres, and experienced emotions high and low in the process. But now we are on our way home. The place we have been dreaming of on the long, cold dark nights.

Camping at Tengboche

I was now beginning to feel some effects of being at high altitude. Normal actions seemed to take much longer and I was surprised how rapidly one becomes out of breath when walking up a gradient. Everything required more effort.

It started to rain a little (low cloud) on the afternoon's final approach to Tengboche. Arrived about 3.45. Drink to stave off altitude headache; thankfully it went almost straight away.

Bitingly cool this evening, especially with the damp air. Dinner was in mess tent at about 6.30 pm. Many other parties here. Tengboche is a regular stopping point for treks.

Had found lunch a little hard to digest (again an effect of altitude). Dinner this evening comprised bombay potatoes, coleslaw, bread pancakes and banana delight. Always hot juice when we arrived at campsite, and tea and biscuits in tent. I bought a can of Sprite for extra liquid.

Went to see sort film about Tengboche monastery but fell asleep. It was warm and the chairs were relatively comfortable.

Everest still seemed a distance dream but after first light in morning we should have a stunning view from the campsite, given clear weather.

It’s 9 pm. Sky is now clear. Giant mountains are silhouetted by twinkling stars. Several of us had discussion about coming days and how we would make it to Basecamp. Determined to keep going.

Some of our party started taking Diamox tablets to help thin the blood and thus combat some of the effects of altitude. Along with others I decided to wait and see how things went the next day.

Last night I slept from 11 pm until 0530 am without a break. Socks staying on tonight as colder but will try to save really warm clothing for the severe cold higher up. Others are already using long johns, hats and gloves etc at night.

Can't imagine what the coming days and nights are going to be like. For us ’office guys’ this is a test of determination and character.

Probably not enough pre-trek training with hingsight - and some more gym work might have helped as tiredness kicks in very quickly. Daytime walks are not technically difficult, though.

Our Yaks are tied up this evening near tents. Their thick shaggy coats glistened in the frost as we turned in. They are lying down but the bells clank every now and then - a comforting sound.

Awoke at 0540. Cold overnight in sleeping bag but only woke a couple of times and didn't need to venture out. People now out of tents. Sun just catching tops of mountains - looks like it will be an excellent day.

I took a short walk to top of the Tengboche site to view the sun rising on mountains. Monks in their colourful robes were gathered outside to witness the rising sun too, a daily ritual. Our campsite is white with a heavy frost and we wait for the warmth of the first swun rays of the day. It happens quickly, like the end of an eclipse. In the sun it iswarm but in the shadows still bitterly cold.

I can see the distant Everest from this campsite but it is dwarfed by other mountains in the foreground. The first part of the trail today is down through woods on sandy ground. Then across a suspension bridge. After crossing we contour around a mountainside, with a fast flowing icy river below.

There is a string of high mountains opposite, with Everest in the distance. The mighty mountain is becoming a familiar, if a little discreet, in the range beyond. Most of this part of the walk is dominated by the mcuh closer to hand and distinctively-shaped Ama Dablam.

At 12 noon it has turned a little cooler and we stop for lunch. By the time we leave an hour later the sun has disappeared as the afternoon clouds build; it will be much colder in the afternoon.

I can hear but not see the roar of water below. By now I have neck ache and a pounding lower head; not sure whether result of gaining altitude. I struggle to walk quickly after lunch. The gradient has become hard work.

The scenery is turning to barren tundra as we lose trees and vegetation. I’ve developed a severe headache in back of neck and have bad indigestion.

We come to a small wooden bridge across a raging tributary. I took a short break here and drank a can of Sprite bought at the campsite shop that morning. Then it was a steep climb up onto open land. Taking it steady, I tried to establish rhythm.

My own head had cleared now but a number of our party  werenow suffering bad headaches and stomach upsets. As a result we will probably stay extra night at our next scheduled stop - Dingboche.

Altitude emergency

No walking this afternoon as having lunch at Kangjung which is also where we are sleeping. Stopped at Everest View Hotel en route and also visited simple Sherpa Museum just after we set out from Namche.

Turned colder as the sun disappeared early, about one o’clock. Thankful to be in the teahouse at Kangjung and by a warm stove.

The youngest member of our group, David, aged 19, rather worryingly asleep in a room at the tea house. He came on lower level easier walk as he was suffering since yesterday evening quite severe symptoms, in my opinion, of advanced mountain (altitude) sickness.

Our trek leader said we’ll see how he is tomorrow, although I heard her at lunchtime tell the Sirdar she was worried. Altitude sickness should be taken very seriously, according to the books I had read.

So far everyone else seems okay. The pace was slower today and easier to cope with. Apparently there are a number of contingency options and alternative routes to cope with a variety of circumstances.

My own cold and cough, which struck me on the second night, is much the same, not really bothering me until I lie down, mainly a running nose and hacking cough.

It’s 15:30 now. There is thick monstrous cloud all around. The light is bright but flat. The tent cold. I will transfer to our room in the tea house soon to keep a little warmer. I expect we should make the most of this luxury as it will only get colder as the trek progresses.

Ninety minutes later after a flurry of activity inside two of our porters burst through the door with a very ill-looking David propped between them. It was dark and they were all dressed for the extreme cold. I sensed a real emergency was unfolding before our eyes.

David was carried back across the mountain by the two brave porters and led by our Sirdar. It was a walk of mercy through the bitterly cold night, taking some four hours to reach the Kunde hospital where we had taken a short break that morning shortly after leaving Namche.

Our trek leader was visibly upset by now and told us she wanted a ‘second opinion’ on David’s rapidly deteriorating condition which had rapidly turned into acute altitude sickness.

It was 21.20 and I had just turned in. We had spent the evening chatting in the warmth, drinking hot tea and playing card games for 10 Rupees a go in the tea house. It was reported back that David had been put on oxygen and was staying in the remote mountain hospital overnight. That was a life-saver.

Cloudy mist hangs over the campsite tonight. Somehow it doesn’t feel so cool and it’s nice to have been inside the warm of the tea room for much of the late afternoon and evening. Heated by a stove powered by Yak dung and lighted by Tilley lamps.

We heard the next day that David had been evacuated by helicopter to hospital in Kathmandu. At the lower altitude he would thankfully make a full recovery - it had been a close shave and this trek was definitely over for him.

Namche Bazaar

A day of crossing and re-crossing the thundering glacial ‘Dudh’ (milk) river, walking through pine forests and cleared areas of terraced fields, growing a surprising variety of crops. A series of small hamlets mark the way as we slowly gain altitude, with spectacular 6000 m mountain peaks unfolding above.

We pass through the gates of the Sagarmartha National Park, the establishment of which has seen a significant attempt to stem the use of firewood in the area. Today, self-contained trekking groups must use only kerosene fuels for cooking, and tea-houses and lodges are encouraged to use kerosene or yak dung.

We follow the river course to the confluence of the Dudh and Bhote rivers, and cross a spectacular high bridge before commencing our ascent to the village of Namche Bazaar, the Sherpa ‘capital’ of Nepal.

It is a tough climb towards the end of the day as the trail zig zags steadily upwards through a forest of pine to a vantage point that provides our first glimpse of distantMount Everest. The trail continues to climb and meander to Namche, and the sight of this prosperous village spread within a horseshoe-shaped valley opposite the beautiful peak of Kongde Ri is worth every step.

At Namche we have emerged from the narrow lowland valleys and after an acclimatisation day will continue into a changing landscape of broad glacial valleys punctuated by the moraines left by retreating glaciers.

This stunningly located gateway to so many paths in history straddles the sides of the valley at some 12,000 feet above sea level - you can almost taste the atmosphere in the air, the sense of hope, joy and wonder to come.

It was called a rest day but after breakfast we were off, thought this time with a light pack. We climbed steadily up the side of the village to a museum and then up towards a view point. It was hard going as we put on 500 m.

The skies had been rather cloudy to start with but the sun came out mid-morning. It was a steep twisting climb, but first chance to see Everest in the distance though was thwarted by distant clouds.  Some of our group walked on to the Everest View Hotel but they didn’t see it from there either.

The walk back down was equally punishing in the heat of the day - twisting hairpin footpaths with wonderful panoramic views of Namche at every turn.
.
By the time we got down I was tired with a headache, even though it had been a fairly slow pace. After drinks and lunch the headache disappeared and so did the weariness.

I spent time in the afternoon looking round local ‘shops’. Very colourful and spread along tiny, steep streets with Yak passing-room only. I bought a fake North Face down jacket at a bargain price which I thought might be useful later for the cold nights at higher altitude.

It seemed my body was adjusting to the altitude. Today’s up and then down again walk had helped. Breathing was now easier than the first night at Namche.

But we would be back at square one tomorrow After the climb out of Namche the first part of the day would be fairly level, then a descent into the valley followed by a steady and steep climb.

Under Himalayan skies

After lunch in a wooden tea house we set off from Lukla about 12 noon for a relatively short up and down trek along a well-trodden path into the valley.

Our starting height was 10,000 feet and the path seemed more down than up. The terrain, if not the view, was not too different from a practice weekend earlier in the summer on Ben Nevis in Scotland. The warm sun was on our backs and the air felt clean and fresh.

This part of our 10 day trek is not a wilderness trail with many people were going back and forth, including the Yaks with their shaggy mountain coats and porters carrying impossible loads.

At this point the altitude didn’t appear to be making any significant difference. We camped behind a lodge and tents were allocated. Tea and local biscuits, then chance to sort out our gear before a meal at 6 pm.

It had been a brilliant first day - from the bustling streets of Kathmandu to the foothills of the Himalayas inside a few hours. Quiet, peaceful and now turning quite cool, with the sound of crashing water in the river gorge below.

We had a briefing from our Sirdar called Tek who was responsible for making sure everything went smoothly. We could expect much harder days to follow.

We would be woken at 6 am with hot tea to drink and a bowl of warm water for washing. Breakfast would be at 7 am, by which time we would have been expected to clear and pack our packs, leaving our tents empty and ready to hit the trail by 8 am, just as the sun was rising above the mountaintops.

We were camping tonight at the tiny settlement of Phakding where the first of many suspension bridges was slung high across the raging river below. In our deep, sheltered gorge the thunderous sound of the river filled the air. The night air was fresh and sharp, and the sleeping bag warm.

Our first night of camping under Himalayan skies was one of relative comfort.

Kathmandu to Lukla

Awoken at 0545 am after a restless, noisy night. Breakfast in the hotel 30 minutes later followed by some last minute packing. By 7 am we were heading in a rickety old coach towards Kathmandu’s national airport. Despite the hour the streets were already chaotic.

At the airport we entered through ‘local' departures. It was a hurly burly, do-it-yourself kind of check in but somehow it seemed to work.

There were already some eight planes awaiting as we were bused out to a twin engined Otter operated by Yeti airways. These planes can make four or five trips a day to somewhere like Lukla, some 30 to 40 minutes of spectacular flying time away.

Localised fog out on the runway meant everything was grounded until the sun was properly up to burn away the early morning mist. We hung around outside the plane with the chance to closely examine what looked like a flying relic of days gone by. Hopefully good enough for one more trip into the mountains.

Thought it’s not entirely logical, I feel thankful that we have two pilots as we career down the runway and buzz up into the air away from Kathmandu.

It’s a tight fit for 16 people and all the trekking gear for 10 days and we have an intimate view of the two pilots at the front. Soon we are flying over hilly farmland at about 10,000 feet. To the left there are distant towering mountain ridges.

As we can see through the cockpit window the tiny mountainside landing strip comes into view. It has to be a pinpoint touchdown here as the runway is short and ends in a wall of mountainside. No second chances as the pilots line up for what must be one of the most exciting landing strips in the world.  It is a unique and truly memorable flight.

The mountainside settlement of Lukla, gateway to Everest, is bustling with people and small aeroplanes and even a couple of helicopters. No sooner has our plane turned into the tiny parking area and another is buzzing down the runway to leap into oblivion over the mountain edge. Bags and people are unloaded immediately.

The airstrip at bustling Lukla was built by Sir Edmund Hillary and his friends to service the Everest region when he began his work of building schools and hospitals for the Sherpa people.

We are immediately impressed by the scale of the huge peaks that surround the settlement, as we greet our Sherpa team and take time loading gear with the porters and yaks.

Our party sets off from Lukla at about 11 o’clock, down from the landing strip through a narrow cobbled street. Tiny shops spill onto the walkway and there is the smell of wood fires with smoke rising into the still air.

We snake downhill on a broad and well-marked rocky trail towards the Dudh Kosi, a raging river that flows from the highest peaks. At 10,000 feet the air is already thinning and cool, and you can taste the mountains with every breath as - it is both intoxicating and exhilarating.
