Imagine being dropped off by a tiny bush plane into a remote wilderness, knowing you are about to brave the biggest challenge you have ever faced. Todd Wells did just that when he led an exploratory kayaking expedition into the heart of the Wrangell Mountains in Alaska. He and his team members were only able to get to their destination at the headwaters of the Chitina River by being dropped off one at a time, with their kayaks strapped to the bottom of the plane. “I had paddled Class V with each of these paddlers before, but this … was probably the biggest challenge that any of us had ever faced,” Wells says. “Our goal [was] just to make it down safely in one piece.”
The Chitina River in the WrangellSt. Elias National Park in Alaska originates right beneath the Logan Glacier. “Just a decade or two ago, the Logan Glacier used to cover this canyon,” Wells says. “Because of climate change and because of the recession of all these glaciers in Alaska, the Logan Glacier has retreated farther up into the mountains and opened up an entrance to the canyon that we've now been able to access.” Now there is a new, raging Class V+ gorge, which was previously concealed beneath the ice.
Wells put together a team of paddlers he trusts who have each spent at least 10 years paddling Class V rivers: friend Ben Mar, friend and photographer Eric Parker, Wells's brother Brandon, videographer Chris Korbulic, and local friend Matt Peters.
The headwaters canyon is about 12 miles (19 kilometers) long, and the team's goal was to paddle as much of the canyon as they could. “We knew that there were probably a couple portages that we would have to make, but as long as we were able to paddle the majority of the river and not have to portage the whole canyon, I was going to be satisfied,” Wells explains. They ended up only having to portage twice for about 500 yards (457 meters), which meant they faced a lot of white water.
“Sometimes when we're in a safer environment, we really push it hard and we try to run every single rapid and really, really push it. But out here on the Chitina, our goal [was] just to make it down safely in one piece and that's what we were able to do,” Wells says. “There are a couple rapids we portaged that potentially we could go back and try to run sometime, but they were really pretty scary and if we were to make a mistake on either one of those rapids, it could have been fatal.”
The team had to prepare carefully for other demanding conditions as well, such as camping in the cold and packing all of their equipment inside the back of their kayaks. “None of us have ever done anything quite like this,” Wells said. “It was a learning process figuring out where to set up camp where we [were] protected from the wind, how to portage and scout rapids safely. It was a difficult challenge for us all.”
The retreat of the Logan Glacier opened up the landscape relatively recently so there are dramatic rugged rocks and not a lot of vegetation. “Just being in the heart of the WrangellSt. Elias National Park was a really, really amazing experience. I'd never been anywhere that felt nearly as remote as the headwaters canyon and the Chitina River. We were seeing wildlife throughout the trip. There were bears and moose and just no human influence at all. It was a really special spot to be.”
This kind of remote exploration is what drives Wells as a kayaker. Doing a first descent down the Chitina canyon was a thrill. “I really feel that Alaska is the last frontier for a lot of explorations, a lot of kayaking expeditions. It's really unique to be able to be up there and explore these places that no one has ever been before.”

14 July 1857: A spectacular glass pavilion in Manchester is filled with 16,000 artworks for the Art Treasures Exhibition
The reign of Anne is like one of those meetings of tidal waters where the voyager is tossed in the hurly-burly of opposing forces till he is sickened and confused, and only discovers the overmastering strength of the dominant current when it has borne him out of the broken water of the tide-way. In this reign struggled for the last time, as equal antagonists, the claims of the prerogative and the powers of constitutionalism.
It is an interregnum between the arbitrary rule of the Stuarts and the law-limited government of the house of Hanover. It is true that the former was put down by the revolution of 1658, but William's whole reign was a struggle at once with those who repented of the share they had taken in the convention, with the non-jurors and Jacobites who regarded all the convention had done as deadly sin, and with the rival ambitions which the revolution had let loose.

Technology image of the week highlights ESA's double-satellite Proba-3 mission that will be flying where no previous member of the Proba minisatellite family has gone before up to 60 000 km away, a seventh of the way to the Moon.
Set for launch in 2019, the two satellites will be launched together into a highly elliptical or elongated orbit, ranging from an perigee (low point) of 600 km up to an apogee (high point) of 60 000 km.
“This long 19.7 hour orbit will allow us to maintain sustained contact with the two satellites using a single ground station,” explains Agnes Mestreau-Garreau, Proba-3 project manager.
“And around the high point of the orbit we will be able to spend around six hours on solar observation or devoted to experimental formation flying manoeuvres.”
The latest member of ESA's experimental Proba minisatellite family, Proba-3's paired satellites will manoeuvre relative to each other with millimetre and fraction-of-a-degree precision, intended to serve as the virtual equivalent of a giant structure in space and so open up a whole new way of running space missions.
As has become traditional with Proba missions, the success of Proba-3's technology will be proven through acquiring high-quality scientific data. In this case, the smaller ‘occulter' satellite will blot out the Sun's fiery disc as viewed by the larger ‘coronagraph' satellite, revealing mysterious regions of our parent star's ghostly ‘corona', or outer atmosphere.
When in Sun-observing mode, the two satellites will maintain formation exactly 150 m apart, lined up with the Sun so the occulter casts a shadow across the face of the coronagraph, blocking out solar glare to come closer to the Sun's fiery surface than ever before, other than during frustratingly brief terrestrial solar eclipses.
The challenge is in keeping the satellites safely controlled and correctly positioned relative to each other. This will be accomplished using various new technologies, including bespoke formation-flying software, relative GPS information, intersatellite radio links, startrackers, and optical visual sensors and optical metrologies for close-up manoeuvring.
Fifteen ESA Member States are participating in the Proba-3 consortium, with SENER in Spain as prime contractor for the satellite platforms and Centre Spatial de Liège in Belgium as prime contractor for the coronagraph.

A 'research station' on the 'peaks of eternal light' would prevent anyone else from approaching. A Harvard-Smithsonian Center for Astrophysics senior astrophysicist, Martin Elvis, has sounded the alarm of how an unfriendly power the Chinese for example could seize control of an important piece of lunar real estate. They could do it legally by exploiting provisions of the Outer Space Treaty, that bars any nation — and by extension, corporation — from owning property on a celestial body, but a loophole in the pact may amount to the same thing, warns Elvis.
The real estate in question are the so-called “peaks of eternal light” that lay around permanently shadowed craters at the Lunar South Pole. Unlike the Earth, which is tilted so the poles are in six months of darkness and six months of light, the moon is almost perfectly aligned with its orbit around the sun. Because of the way the moon tilts, these peaks are bathed in sunlight for most if not all of the time, which means you can have an almost continuous power supply, ideal for a photovoltaic power station. Thus this part of the moon would be perfect places to erect solar power stations that would support mining operations in the nearby craters, where water and other valuable resources such as Helium 3 have been deposited over billions of years.
Elvis says that provisions in the treaty allow nations to exploit resources, including through establishing research stations, and bar others from disrupting such endeavors. In some cases, this could amount to de facto ownership, Elvis said. As China and Japan plan moon landings, and corporate leaders eye their own space ventures, the loophole has gained in importance.
Not only are China and Japan planning a series of missions to the moon, China just announced that one of its missions would land at the south pole somewhere. There are also private companies, stimulated by the Google Lunar X Prize. And there are two teams that have rocket flights booked for 2017, an Israeli team and Moon Express, a U.S. company. And they seem to be looking at being able to send a lander to the moon for $50 million, which is very cheap by space standards. So this makes it a very urgent issue.
People will soon want to start putting power stations on these Peaks of Eternal Light and use them for exploiting the resources. What we pointed out is that a very simple experiment, similar to the one that the Chinese have already landed on the near side of the moon, [could serve to limit access to others]. You land on one end of the ridge and a little rover goes off, trailing a little copper wire behind it. It trundles off to the other end of the ridge, and that would then form a radio telescope to explore the Cosmos.
During the 40th Anniversary Commemoration Event for Apollo 17, moonwalker and NASA retired astronaut and geologist Harrison Schmitt said "one of the most significant contributions of the Apollo Missions was confirming the presence of Helium-3 on the moon."
Helium-3 (He-3) is a light, non-radioactive isotope of helium with two protons and one neutron. Its presence is rare on Earth, it is sought after for use in nuclear fusion research, and it is abundant in the moon's soil by at least 13 parts per billion (ppb) by weight.
In 2007, shortly after Russia claimed a vast portion of the Arctic sea floor, accelerating an international race for the natural resources as global warming opens polar access, China announced plans to map "every inch" of the surface of the Moon and exploit the vast quantities of Helium-3 thought to lie buried in lunar rocks as part of its ambitious space-exploration program.
Ouyang Ziyuan, head of the first phase of lunar exploration, was quoted on government-sanctioned news site ChinaNews.com describing plans to collect three dimensional images of the Moon for future mining of Helium 3: "There are altogether 15 tons of helium-3 on Earth, while on the Moon, the total amount of Helium-3 can reach one to five million tons."
"Helium-3 is considered as a long-term, stable, safe, clean and cheap material for human beings to get nuclear energy through controllable nuclear fusion experiments," Ziyuan added. "If we human beings can finally use such energy material to generate electricity, then China might need 10 tons of helium-3 every year and in the world, about 100 tons of helium-3 will be needed every year."
Helium 3 fusion energy - classic Buck Rogers propulsion system- may be the key to future space exploration and settlement, requiring less radioactive shielding, lightening the load. Scientists estimate there are about one million tons of helium 3 on the moon, enough to power the world for thousands of years. The equivalent of a single space shuttle load or roughly 25 tons could supply the entire United States' energy needs for a year.
Thermonuclear reactors capable of processing Helium-3 would have to be built, along with major transport system to get various equipment to the Moon to process huge amounts of lunar soil and get the minerals back to Earth. The harvesting of Helium-3 on the could start by 2025. Our lunar mining could be but a jumping off point for Helium 3 extraction from the atmospheres of our Solar System gas giants, Saturn and Jupiter.
UN Treaties in place state that the moon and its minerals are the common heritage of mankind, so the quest to use Helium-3 as an energy source would likely demand joint international co-operation. Hopefully, exploitation of the moon's resources will be viewed as a solution for thw world, rather than an out-moded nation-state solution.
