Coming Soon..... Stowaway

In 2015 Joe Penna AKA MysteryGuitarMan contacted me about a movie he was writing about a crew headed to Mars, asking if I could offer some technical advice about space stuff. I jumped at the chance to get involved in a project like this and over the last few years I've been answering questions, sometimes doing the math and offering suggestions o...

Improvising And Ad-Libbing OSIRIS REx

I rarely write scripts, usually I'm working from notes and bullet points, and sometimes that means a lot of cutting of moments where I start saying things and then realise I shouldn't be saying it, or, rewinding to say something else first. 

With the recent OSIRIS REx video I think my heart was very much into the subject and this is t...

Behind the Scenes - Making Fuel Injector Animations

In my recent video on fuel injectors I made all the animations using a particle effect filter that's intended to look like a blood spray, here's a quick rundown of how I did this and for those who want to use the animations they're alll here:

Black Hole Raytracing

I've sorta become addicted to building out a proper black hole raytracer to do an updated version of my 360 video showing what it looks like to fall into a black hole.  I started with code from this page as a reference  http://www.madore.org/~david/math/ker...

Best Stuff Of The Decade Video - Games & Movies

I thought this might make a decent video but decided I didn't have the time to actually make it into a full production, so I'm sharing it here for those who are interested.

Sometimes things don't work out as planned

I'm trying to depict the location of every satellite relative to the space station, but I was stuck with the problem of wanting the Earth to look decent, so I used the only scriptable rendering environment I knew - POVRay - and used that to make 360 renders of the Earth from LEO.

Boy it was slow..... so I turned the planet from an isospher...

Taming Liquid Hydrogen

Another free NASA historical book I've been reading through, I wish I'd read it before making yesterdays video because there's a fun anecdote in there involving hitting a balloon tank with a sledgehammer. Also the reason why Pratt And Whitney got to develop the RL-10 engine despite having no rocket engine experience before.

Space Shuttle Main Engines Upgrades

One of the main references on my RS-25 reflight video is this NTRS presentation on the multiple generations of the Space Shuttle Main Engine design. The engines were upgraded over time and swapped between orbiters as missions required working engines. 

And of course now these veteran engines are going for one last spaceflight together...

Look at the size of that thing

If You Could See All The Satellites WIP

Using the satellite data code from the weekend I started working on the idea of showing what things would look like if you could see all the satellites in the sky overhead, this is the first stage proof of concept rendered into a 360 video on youtube. 

THis needs a lot of work, it's missing all the debris and classified satellites, th...

Science Hack Day - Watch The Skies

This weekend I participated in the 10th San Francisco Science Hack Day http://sf.sciencehackday.org/. An event where people get together to design and build things, some are stupid toys, others are sceintific experiments and some even position themselves as future product prot...

Video from ESA/ESTEC Before Editing

I've not had time to edit the footage I'm recording on my trip to ESTEC, but I figured these are a couple of bits which don't need any editing to be interesting. The center has a public museum which includes a typical collection of space hardware, but my favourite part was a Viking 2 engine from a 1st generation Ariane rocket which had been cut ...

Space Debris & Solar Activity

I found this image in a NASA publication about orbital debris and wanted to share it. It shows 2 sets of data on the same chart. One line shows the level of solar activity, as it changes over the 11 year sunspot cycle, the blue points show the orbits of debris from the 1985 ASAT demonstration where an F-15 destroyed the Solwind satellite using a...

The Last Ever Single Stick Delta Rocket

Tomorrow morning the last of the single stick Delta IV's will launch, leaving the Delta IV Heavy as the only Delta design still flying. Last year we saw the final Delta II as well. The Delta IV has been more expensive to fly compared to the Atlas V, so it's only found use on military payloads, and a handful of civilian spacecraft which needed ev...

Kerbal Space Program 2 Is Coming

I owe a huge part of my youtube success to the popularity of this game, when it appeared I had a step up from other gamers because of my background in astronomy. When flying the rockets I made I'd talk about science, but now I talk about science and only occasionally use the games when it helps.

It's not being developed by the original tea...

New Tune By Test Shot Starfish - AKA 'SpaceX FM'

I'm a sucker for their music as background for working on all sorts of things, especially when they borrow liberally from space themes for their SpaceX soundtrack work.

If you've ever wondered about the name, it's a reference to the highest altitude nuclear weapons test - 'Starfish Prime' which kicked the earth's magnetic field creating a ...

A Rocket Casts A Shadow On Its Own Exhaust Trail

This morning's AEHF-5 launch by the ULA was rather spectacular, there were some minor delays and the rocket lifted off about 40 minutes before sunrise. This lead to a highly visible trail which was visible from hundreds of miles away, but the on-board camera also recorded something I don't remember seeing in a launch. 

After the rocke...

Learning New Things About The F-15 Launched ASAT Missile

I've been doing some research for a story about the only case of a pilot 'shooting down' a satellite and in the process found that I'd misunderstood the launch trajectory for years. The missile had to be launched from a climbing f-15 in close proximity to the satellite's expected track, since the missile can't get to orbital velocity I'd imagine...

Ariane & SpaceX Launches Today

For those who like watching live, Ariane is about to launch and is livestreaming:

SpaceX is planning to launch the AMOS-17 communications satellite, this will be a free launch to make up for that unfortunate RU...

Amazing Fairing

SpaceX just released this stunning video from the recovered fairing during its controlled reentry. Looking back into the ionized air from the reentry, probably the fastest reentry of a fairing to date.

The colors are likely not truly representative, the purple color is typical of the engineering cameras used by SpaceX which don’t have n...

A Big Day On Space TV

Earlier in the day NASA performed a spectacular live test of the Launch Escape System for the Orion Capsule intended to fly on SLS - I missed it live due to being on a train, but it looked like a success. Yes, it was intentional that they were going to drop the capsule into the ocean without parachutes.

Deep space update from deep inside Europe

With asteroid day events taking all my time I haven’t had any video making opportunities - so here’s a quick update while on the road.

Answering Questions

I thought some of you might be interested in my answers to these 4 questions, I recorded these for a currently unnamed TV production but without that context I can share them now:

My Earliest Space Video From Over 20 Years Ago

I created this video using POVRay in the 1990's showing a spacecraft being sent to divert a comet using a nuclear blast. I didn't use a modeller, I hand coded all the scene files, all the animations, and even wrote an asteroid generation system that started with a cube and subdivided it into polygons. 

It has several obvious mistakes ...

Omegaaaaad - OmegA Rocket First Stage Fails During Test

Northrop Grumman just livestreamed a full duration burn test for the first stage of their OmegA rocket, and seconds before the end of the test the nozzle disintegrated.

This SRB is very similar to the ones used to launch the Space Shuttle and planned for the SLS, however it's modernized compared to both using new materials for the casing a...

Asteroid (33434) Scottmanley = 1999 FU = 1989 GA6

It's official, I now have a minor planet named after me - asteroid 33434 was renamed 'Scottmanley'.

It's a small main belt asteroid, 2.74 AU out with an eccentricity of 0.064 and period of 5.02 years. It was discovered in 1999 by Alain Maury, but later analysis found the object was previously seen in 1989 and all the way back to 1954. So t...

Mariner I Research - Some 'Light' Reading

The 'Why Rockets Fail' series has been something I wanted to do for years, but I always wanted to start with Mariner I - it was supposed to be the first space probe sent to another planet, but instead ended up in the ocean after a guidance failure. And the root cause of the guidance failure was a programming error in the computer.

Arthur C...

Blue Origin - Blue Moon ‘Hot take'

I’ll have a full video up for everyone tomorrow, but I had 5 minutes so I recorded this for those who are interested.

Kerbal Space Program Doesn't Teach....

I like doing these deep dives on rocket science related subjects, they take a lot of work to put together and cross reference all the sources. I have a few options for the next one, most with lots of supporting research already in the bag.

Which of these would people like to see? 

Or do you have other details that you think woul...

Hullo!

So, yes it's official, after many requests to start a patreon I have this! 

There'll a bunch of extra updates for supporters, and I hope that if you take the plunge and support me that you'll feel it was worth it. I don't really have the spare time to make extra videos similar to those on youtube, but I will have a few 'off the cuff' ...
