Well, after a 10 month absence, I’ve decided to get back to work on this blog. I do so because I love astronomy, and want to continue learning about it and sharing it with people. If you’re wondering why I stopped, the answer is that I left Primland resort in order to start a new life with my beautiful wife. It was an honor and privilege working at the resort, and if you get a chance to go, I definitely recommend it. I simply chose to look at the stars somewhere closer to home. That said, this blog will continue and I will post weekly whenever there is an astronomical event that sparks my interest.
I found a great video from DeepSky Videos.com, where an astronomer probes the depths of a beautiful dwarf galaxy that is encircling our own like a comet. Only recently has NASA been able to penetrate this galactic cloud, and here are some of the facts about this unique object:

Like most of us in this economy, NASA has had to make some budget cuts. When they released their 2014 budget, it cut over $55 million from the previous year. Planetary studies have been hurt the most with 300 million cut from the budget. Looking at this, it’s clear that studying our solar system is just not a priority anymore; NASA is taking new directions with its research and some of its new plans are quite exciting.
For Example, NASA is increasing its funding to support Earth science; tracking man made and natural changes to our planet, including pollution and climate changes. The idea is that hopefully learning more about how to protect our planet and to protect ourselves.
In addition, there is also a program in place to start manned missions into space once again. I’ve written about this before when I mentioned the Orion Spacecraft, the first manned spacecraft designed for interplanetary orbit in 30 years. NASA is already building the space capsule, and the whole project should be finished by 2021.
BUT, there is one item on the NASA budget that seems right out of science fiction- The capture and mining of ASTEROIDS!
That’s right, President Obama approved a new project designed to send a special craft out into space for the purposes of finding and capturing a Near-Earth Asteroid (NEA), and then bringing it back down to Earth to study, and eventually mine it for its contents. This might sound like something out of a James Cameron movie, but it really is part of the NASA budget, and the project is getting underway as we speak.
So why mine asteroids? To answer this question, I’ll break down the arguments and, (to continue with the Sci-Fi theme I’ve begun), I’m going to list them one by one, and name them after some awesome Sci-fi movie titles.
1. The Abyss/ Avatar-
According to scientific estimates, one asteroid may contain over $20 TRILLION dollars worth of precious metals, as well as iron, nickel, and cobalt. Ultimately, it might improve NASA’s budget and the world economy greatly to invest in asteroid mining. Plus, unlike Avatar, all of these asteroids would be uninhabited, making mining comparatively easy from a socio-political standpoint. Still, as you can see from the video above, to make this plan economically viable on a large scale we would need to develop vastly superior rockets, to keep the cost of sending rockets up into space all the time lower than the profits reaped from the asteroids themselves. As far fetched as this idea may seem, companies are already working to make it a reality. Imagine NASA beginning a new industry as unlimited as the universe itself!
2. Titan AE
If our planet were to suffer a cataclysm, (which could literally happen any day now), we will need to find a new way of getting water, oxygen, and the ingredients to create plant life. In addition to precious metals, asteroids also contain all of these. Bits of oxygen and hydrogen are locked up within the rocks. In addition, we know that asteroids contain ingredients for life, since 3.5 billion years ago, they helped develop life on our own planet. Therefore, if we ever need to leave the Earth, it makes more sense to mine our raw materials from asteroids, rather than taking everything with us. Of course, getting us off the Earth, is a much bigger problem:
As the Russian meteor explosion grimly reminded us, Earth could literally be hit by an asteroid at any time without warning. This is why the primary goal of the Asteroid Retrieval project is to study asteroids and determine how best to combat a potential threat. Lest we forget, an asteroid destroyed entire species on our planet 65 million years ago, and we need to be careful to make sure it doesn’t happen to us (cue the dramatic music).
So there you are, the major reasons why it’s a good idea to find asteroids and bring them back here. We eagerly await NASA making this project a reality, so that they make space a safer and more profitable place to live. As one more treat, here is a NASA animation of how the project might look, with dramatic Hollywood music underscoring for good measure.
Asteroid DA 14 is due in the skies in North America in the next two hours, so I thought I’d provide links to the best live coverage. First, here’s a
live feed from NASA that begins at 9PM EST:
Secondly, here’s a compilation of clips from astronomers at SLOOH.com, which was featured on Dateline last night:
That’s all I got for now, I gotta get ready for the tour tonight!
