Private space companies are eyeing the Moon's resources for mining

The race to develop lunar landers that can prospect for valuable minerals, mine them, and send them back to Earth, is proceeding along, slowly but surely.

The MX-1 lander has just been unveiled by Moon Express, a private space company. It's not an amazing piece of technology, not when compared to something like Nasa's $2.5bn Curiosity rover currently on Mars, but it does represent an early contender in what will become a decades-long race to mine the Moon for profit.

Private space companies have started to appear around the world, but particularly in the US, as the price and technology barriers for space travel fall and governments turn away from nationalised space policies. Some companies, like Virgin Galactic, are planning on giving tourists an expensive thrill, while others, like SpaceX, see a gap in the market for cargo services. This month, SpaceX put a commercial satellite into orbit for the first time, and last year it made history as the first company contracted to send a cargo resupply mission to the International Space Station.

The US government in particular, through Nasa, is starting to encourage private space companies to bid for contracts, creating an industry that is a bit like defence - one large state-funded agency that collaborates with private companies on projects and which outsources certain parts of its research and development. This is where Moon Express comes in. Here's how it describes its new probe:

The main MX-1 rocket engine is a dual mode bi-propellant system that also uses kerosene as an after burner to give the spacecraft the punch to break out of Earth orbit, accelerate to faster than a bullet, travel a million miles to beyond the Moon, and come back to break to zero velocity using its outboard thrusters as it touches the lunar surface. The spacecraft is designed to ride to Earth orbit on low cost secondary payload opportunities aboard commercial launchers like the SpaceX Falcon 9 that are radically reducing the cost of access to space.

About the size of a large coffee table, the MX-1 is a completely self-contained single stage spacecraft that can reach the surface of the Moon from a geosynchronous transfer orbit (GTO) commonly used to place communications satellites above the Earth. It is also designed to be a flexible spacecraft platform that can support a number of applications including serving as a flexible, agile upper stage for existing launch systems enabling Earth orbit cubesat deployment, satellite servicing, and "space tug" applications such as cleaning up space debris.

This first version of the MX-1 is designed to do one specific thing - land on the move, drive around a bit, and send back some high-definition video footage. Those are the criteria that, once fulfilled, will win the $20m Google Lunar X Prize. The prize, sponsored by Google but offered by the X Prize Foundation, is the latest in a number of space-related challenges inspired by the $25,000 Orteig Prize of 1919. That's the one Charles Lindbergh won by completing the first non-stop flight between New York City and Paris. The aim of these prizes is to give small private companies something to aim for beyond just the record of being first.

There is quite the incentive to get to the Moon, though. We use a lot of what are known as "rare Earth minerals" - with wonderful names like cerium, neodymium, and dysprosium - in electronics, but they're a finite resource. They're very common throughout the Earth's crust, but the name comes from the fact that they rarely appear in concentrations high enough to make mining economical. This has made the mining of such minerals a geopolitical issue, with politicians in the US and Europe threatened by China's control of most of the world's mines.

The Moon, it's thought, formed out of molten rock ejected from the early Earth's crust, and as such should have plenty of rare Earth minerals lying around waiting to be prospected and mined. Helium-3, an isotope essential for operating nuclear fusion reactors, is also theorised to be abundant on the Moon. Newt Gingrich had this in mind when he proposed building a Moon base as part of his failed campaign to become the Republican candidate for president in 2012.

That's if we can find it, of course, and the current UN treaty that governs the Moon - the 1966 Outer Space Treaty - effectively treats it like international waters. Private companies can explore and mine it all they want. We're many decades away from seeing established mining colonies on the Moon (and even then, expect them to be completely robotic), but keep an eye on companies like Moon Express, as they'll be the first ones up there.

Understanding anxiety – my inside view of a debilitating disorder and how to control it

Following a number of recent anxiety attacks, I set out to learn why this happens to me.

As I stepped out of the office one evening after a routine day at work, I found myself glued to the floor. Legs bolted, knees quivering, heart racing – I was cemented into the ground by something paralysing.

I had to work out what was happening, and fast. Was a looming deadline holding me back from leaving? Was an unread message on my phone stopping me in my tracks? Perhaps fatigue had set me on edge. Or that passerby with an unsettling stare caught me off-guard. Maybe it was something more surreal; maybe a sense of dread had taken over, as I started to perceive each onlooker as a potential source of fear. Whether it was all of those things or none of those things, I eventually realised that the sticky situation I had found myself in was the onset of an anxiety attack.

Anxiety is a disorder of varying forms. People may be affected by generalised anxiety disorder – characterised by excessive worrying (often without an identifiable trigger), a specific phobia or panic disorder, in which terror can overwhelm a person without warning. The sufferer experiences physical and mental symptoms of distress that include a feeling of restlessness, shortness of breath, and agitation, exacerbated by the uncontrollable spiralling of their thoughts, which can often be self-deprecating and debilitating.

I had been in this situation before. The rising tension makes for an overwhelming and often paranoid experience, but my awareness of the fact that I was indeed having an anxiety attack was enough to know that this feeling wouldn’t persist for an indefinite amount of time; it would eventually pass, as all anxiety attacks do.

After roughly half an hour of concentrated breathing, conscious changes in thought patterns and eventually moving to a quieter spot, I had managed to calm down.

Though I had managed my anxiety attacks before via similar means, I was curious to know – what exactly was happening during my attacks? What can specifically be done while they’re happening? And could the panic and jitters of anxiety ever be beneficial?

The biology of an anxiety attack

The biological basis of an anxiety attack is tied to the actions of the body’s autonomic nervous system – a division of our nervous system that, without conscious control, regulates our bodily organs and systems.

When stimulated, the autonomic nervous system kicks into gear, causing the release of adrenaline into the bloodstream. And that’s when things flare up.

Pulses of adrenaline are produced in response to a stimulus  one that causes the body to kick into a defensive fight-or-flight mode. With anxiety, these stressful stimuli include excessive thoughts, heightened worries, trauma triggers and objects posing as threats. Even subconscious phenomena have been proposed as provokers; it is known that sufferers may wake up from a night’s sleep in a bout of panic. The stimuli add to the existing level of distress, making a person’s breath shallower, often inducing profuse sweating, and initiating a dark foreboding, all in the space of a moment.

Combating anxiety

According to the NHS, there are a number of techniques that can be employed to manage the distressing symptoms of an attack. Staying in a fixed spot, deep breathing and actively issuing a challenge in your mind to the fears on which you may be fixating are crucial things to do in the immediate stages. I wasn’t sure whether in my latest case I had done this instinctively or out of habit from past struggles. Either way, the methods were relieving.

The end of an attack is reached through an eventual depletion of adrenaline, which tells the body that it no longer needs to be on high alert. It brings with it tiredness but a welcome passing of the crisis. However, without a longer-term, pragmatic approach to tackling the disorder, it’s almost certain that an individual will face another intense period of anxiousness. So how should anxiety sufferers manage the issue over a longer period of time?

This is where therapy can be an extremely useful form of intervention. Cognitive behavioural therapy (CBT) is the most common form of therapy for the disorder, with research demonstrating its effectiveness in treating the closely related disorders under the umbrella of anxiety. CBT focuses on a reconfiguring of thought patterns, shifting perceptions and a redefining of negative sources of fear.

Recently, I spoke to David Potts, a CBT therapist, to discuss how therapy can be of benefit. He said: “In therapy we'd work on specifics. It would involve telling yourself what the triggers are. Often people have very negative views about what's happening to them [during an attack]; they'll think I'm having a heart attack or I'm going to die and those kinds of thoughts form a vicious cycle and the panic gets worse.”

According to Potts, being attuned to the occurrence of an anxiety attack is essential in taking active steps to overcome it. It can facilitate the process of calming down, allowing the person in the midst of an attack to separate the thoughts in their mind from the reality of a particular situation.

Therapy can also offer an individualised approach to understanding a person’s anxiety. Potts told me: “Often, from a therapy perspective, we are considering what’s happening to them [the patient] in their lives that lead them to be more anxious than other people. It could include things they’ve experienced in childhood, it could be ways that families are, or it could involve ways that they’ve learnt to manage different emotions.”

Beyond therapy, medication is available to aid anxiety. Appropriate to a disorder that can affect people in various ways, there are different types of medication. Selective serotonin reuptake inhibitors (SSRIs) are the most common form of medication. SSRIs are antidepressants that seek to increase levels of serotonin in our brains – a neurotransmitter thought to be central to the maintenance of mood. Other drugs available (in case of side effects from SSRIs) include serotonin and noradrenaline reuptake inhibitors (SNRIs), pregabalin and benzodiazepines. Though alleviating, medication is something that should supplement forms of therapy, as the pills themselves won’t solve the social triggers and problems that cause anxiety.

As people have increasingly moved towards holistic lifestyles, emphasis on exercise and dietary intake has been elevated. Eating healthier has been linked to reduced symptoms of anxiety, while exercise has been proven to reduce levels of stress in the long run. Reduced stress equates to a reduced risk of an anxiety attack.

Changes to the brain from exercise have been documented too. Researchers at Princeton University found that physical exercise generates excitable new brain cells in the hippocampus – an area of the brain involved in emotional responses. Though the excitability of the neurons would generally be unfavourable (priming the brain for anxiety), researchers found that the impact of exercise was one which had a calming effect, as the exercise was able to switch off the newly-generated, excitable neurons at times when they weren’t required.

When just a ten-minute walk has been shown to offer benefit, there seems to be very little to oppose the implementation of exercise as a form of therapy for anxiety.

Living with anxiety

Perhaps surprisingly, anxiety can be harnessed as a tool of empowerment for some. When it occurs at a smaller scale, it can serve as an informative warning against stressors, and help an individual focus and pinpoint their attention.

As a sufferer, acknowledgement of anxiety seems to be the key to unlocking the resources that can dull its impact. With carefully paid attention, responsibility and mindfulness, the waves of anxiety threatening to drench you can be reduced to smaller, more manageable ebbs and flows.
