SimplePlanes VR is now available

After far too many late nights of caffeine-infused coding and 3D modeling, we are proud to present SimplePlanes VR. Strap a VR headset to your face and grab the stick and throttle in front of you to fly. Flip switches, push buttons, crank levers, slide throttles, and so much more. Download community-made aircraft without leaving the comfort of your VR headset. SimplePlanes VR is the most feature-packed VR flight sim you'll find for the meager cost of a gourmet sandwich. We hope you enjoy your flight! SimplePlanes VR is a standalone game and does not require SimplePlanes. However, if you own SimplePlanes, then purchasing SPVR will unlock VR mode in your original SimplePlanes so you can easily switch to VR mode and see how your builds are looking in VR.

Explosions in SR2
When you are building rockets, you're most likely going to run into the occasional rapid unscheduled disassembly. It happens to even the most experienced rocket surgeons. You might as well embrace it and take advantage of the opportunity and snag some spectacular photos. In addit

Beta Testing (PC/Mac)
We have recently started (secretly) beta testing SimpleRockets 2 for PC and Mac. We started with a very small group of people, just to ease into this and make sure nothing exploded, including our brains. So far we've had about 165 bug reports submitted and only Nathan's brain has

Planned Burns in SimpleRockets 2
With rising fuel prices, we'd hate for you to waste your precious RP-1 guessing how to burn your engines to get where you want to go. In SimpleRockets 2, you can plan your burns by clicking on your current orbit and adding a Planned Burn. From there you can easily drag gizmos aro

Ion Engine in SimpleRockets 2
The tyrannical Tsiolkovsky rocket equation cannot be avoided. The only way for rockets to accelerate in space is by expelling some of their mass. Most engines do this with combustion, which expels huge amounts of fuel mass at a respectable velocity. This gives great acceleration
The tyrannical Tsiolkovsky rocket equation cannot be avoided. The only way for rockets to accelerate in space is by expelling some of their mass. Most engines do this with combustion, which expels huge amounts of fuel mass at a respectable velocity. This gives great acceleration (and an impressive fireball), but very poor specific impulse. Specific impulse is like gas mileage for rocket engines. Ion engines, on the other hand, take a different approach. They shoot out a minuscule amount of fuel mass, but they do it at insane velocities. Around 40 kilometers per second (90,000mph). This results in a force that is about the equivalent of lifting a piece of paper into the air. That's not very impressive, but they make up for it by taking their time with their fuel. Ion engines can "burn" for weeks, so this small force can add up to an extremely impressive delta-V. This little satellite I made has a delta-V of 14,533 m/s and a burn time of about 72 hours. Here are the details:

Thrust: 0.050 kN (Yep, that's right, just fifty Newtons)
Mass: 50 kg
Price: $100,000
Specific Impulse: 11,515 s
Fuel Type: Xenon
Electrical Consumption: 100kW
Height: 0.25 m
Diameter: 0.6 m
Max Gimbal Angle: 0 degrees
Given the extremely long burn times, these engines aren't very useful when playing the game at normal speed. This weekend I've been prototyping how to use these engines while playing the game at up to 1,000x fast-forward mode. It makes playing with these engines far more enjoyable.

The cargo bay will open the door to many possibilities. The most obvious being the space shuttle. There are many more possibilities, but it really hinges on your creativity. I know the creativity of our players is far greater than my own and I can't wait to see what you do with them. The cargo bay is our most complicated procedural part. It can be resized just like the fuel tank, so it can take on an infinite number of shapes. You can also change the angle the doors open as well as their speed. My son just pointed out to me that the green one looks like a coffin. That wasn't the intention, but just add that to the list of things you can make with the cargo bay part. You could also use it to house custom-made, retractable landing gear. Or you could make a bomb bay (we don't have bombs, but you can pretty much make anything with the fuel tank part). Or set the open angle to zero and use it as a hollow fuselage. Here are the part details:

Mass: Your
Price: Heart's
Size: Desire
Max Open Angle: 0 to 150 degrees
Opening Speed: 10% to 250%
Also, in case you missed it, here are some screenshots of a Space Shuttle that Kevin made a few weeks ago. (The cargo bay has changed a lot since then). Now that I have you, I should mention a little something about our launch date. Today we looked over the remaining tasks and the long list of bugs and we came to the conclusion that we are extremely unlikely to launch by end of summer (Sept 22nd). We are now putting our launch date in October. I am confident this will be the last slippage of schedule. If I'm wrong, I will eat black licorice. I hate black licorice.

Pixel Pop Pictures and Virtual Tour

Nav Sphere in SimpleRockets 2
The Nav Circle in SR1 made it very easy to control rockets in a 2D game. It took me a while to figure out the best way to extend the Nav Circle into three dimensions. I ended up with basically two nav circles: one for heading and one for pitch. The end result is now called the Na

Re-Entry Effects in SimpleRockets 2
They said the Apollo 11 command module re-entered Earth's atmosphere at Mach 36 and temperatures of the air in front of the heat shield reached nearly 20,000° degrees Fahrenheit, which is well beyond the melting point of sanity. Today, I loaded up the latest build of SimpleRocket

Our newest engine, the Apex I is an absolute beast. It's heavy, expensive, and drinks RP-1 like there's no tomorrow, but it will have the power to get even your most poorly engineered contraptions into space. It dwarfs the Mage I engine in size, power, and visuals. Here are the details:

Thrust: 3,200 kN
Mass: 3,500 kg
Price: $8,500,000
Height: 4.2 m
Diameter: 3.0 m
Max Gimbal Angle: 2.5 degrees
Fuel Consumption: 1,350 L/s
Specific Impulse: 298 s
Here's a bonus shot of it in a highly ill-advised use case. Can anyone guess the inspiration behind this engine? I'll give you a hint, if you are on a PC, the name of the engine is on your keyboard...

*Note: Check the FAQ here before asking questions.* We've just completed development of the second engine in SR2. The Pixie engine is a much smaller alternative to the Mage engine with far better gas mileage. This makes it suitable for those second stages destined for Smoon. With an accordingly lower thrust, it is also a lot easier to land on a low-G planetary body without getting into an endless cycle of up-and-down that I often find myself in when trying to land with a Mage engine. Here are the details:

Thrust: 50 kN
Mass: 75 kg (165 lbs)
Price: $150k
Height: 1.0 m (3.2 ft)
Diameter: 0.7 m (2.3 ft)
Max Gimbal Angle: 10 degrees
Fuel Consumption: 15 L/s
[wiki=en]Specific impulse[/wiki]: 339 s
Max Torque: 5 Nm
Here's a bonus shot of it in action. Also, I just wanted to let everyone know that I'm going to start posting blog updates every other week instead of every week. It's been fun, but these posts take a lot of time to put together and as we continue to slip further and further behind schedule, I need to use any extra time I can find to focus on development. I hope you understand!
