SpaceX Lands the Faclon9 First Stage - A revolution in Rocket Science and Engineering

Today, at 8:33, Spacex made history. They landed the first stage of their Falcon9 rocket after having it successfully deploy a second stage into low earth orbit.

The Video is here:

Unlike other rocket companies, Spacex in not making small hops - they did that 2 years ago with their grasshopper rocket. In fact, this is how they tested the initial avionics systems that would be able to land the rocket in a stable position autonomously. Here is some footage:

Unlike the companies that makes these hops, Spacex has to use this stage to help get payloads into low earth orbit… and then recover it! This is incredibly difficult and requires an advanced retro-trusting maneuver that has never been successful - until now! The diagram below shows this trusting maneuver, which happens shortly after the second stage has decoupled and ignited.

Spacex claims that this is similar to trowing a pencil over the Empire State Building, then having it flip perfectly, then have it fall into a shoebox… easy enough right?

Only, in real life SpaceX isn’t shooting a pencil… they are shooting a rocket! This is the pad that the now famous falcon9 rocket landed on:

Now you might ask, why does this matter? This means space will become cheaper! We can already build satellites that are less than $10,000, as a matter of fact I’m building a small satellite with a team right now! As it currently stands, space travel is too expensive for creative people to take risks. Now, thanks to SpaceX, we may be mining or visiting asteroids, visiting the moon, visiting mars, or doing something crazier - and we may be doing this very soon! The Falcon9 rocket costs $54 million to build but only $200,000 to refuel… let’s put this in perspective… That’s the same amount that it costs to refuel a Boeing 747 (which is the airplane that consumers use to fly around the world). This means that space travel could be as cheap as air travel very soon! Way to go SpaceX!

The Mystical World Of Mushrooms Captured In Photos

Most people consider mushrooms to be the small, ugly cousins of the plant kingdom, but theirs is  surprisingly beautiful and wonderful world waiting to be explored. These beautiful mushrooms, captured by enthusiastic nature photographers, are a far cry from the ones you find in the woods or your local grocery store.

Most mushrooms, as we know them, are actually just the reproductive structure of the fungus they belong to – their fungal networks expand far further underground, and some fungi don’t even sprout the sort of mushrooms that we’re used to seeing. In fact, depending on your definition of “organism,” the largest living organism in the world is a fungus – there’s a honey mushroom colony in Oregon that occupies about 2,000 acres of land!

Courtney’s Big Space Book Recommendation Post

Okay, so, hi. It has come to my attention that I have gained a lot - a lot - of followers over the last few weeks due to hype for The Martian. Rad.

So, with that in mind, I’ve decided to put together a bunch of non-fiction space recommendations for y’all. Since an anon asked a few days ago, and I kindof want to do it more justice.

If you are new to me and my blog, you might not be aware that I am a gigantic fucking nerd for human space flight and exploration, and I have a boatload of dumbass blogs about it. So, uh, I’ve read a lot of books. Like, lots.
