Introducing Project Perseus….

(July 30th, Cuyahoga Falls, OH)

Born from the Pegasus booster project, we bring to the world, the Perseus Medium Power Booster.

Perseus booster #1 (Eagle) after a fresh coat of paint.

Here’s the quick rundown:

Stronger, Lighter, Faster. The Perseus launch vehicle system was developed to allow for heavier payloads than the Artemis booster can lift, and at much faster speeds.

The Artemis boosters reach their maximum capacity with loads slightly heavier than a standard 9 volt battery.  To lift anything heavier involves going faster than the 250 MPH limit of the Artemis design.

This is where Perseus comes into the picture. Built to go much faster than 250 MPH (the design can easily go near supersonic speeds) and being much lighter, many more electronic payload experiments are possible, including dual deployment systems to allow us to send this rocket to over 2,000 feet in altitude.

One neat feature is slightly raised launch lugs, so the launch rod doesn’t rub against the body (causing friction).  This feature was pioneered on the Pegasus booster.

Another feature brought over from the Pegasus booster is “through the wall” fin mounting, which is the secret behind breaking the Artemis Booster speed limit.

This rocket also features a slightly advanced version of the ejection baffle system / parachute bay configuration used in the Artemis boosters.

The first flight of Perseus booster “Eagle” (Mission PLS-001) is set for August 14th.

The booster is named after the famous “Eagle” lunar lander that took man to the moon for the first time.

The rockets have names!

Of all the rockets we’ve built and flown, only one had a name.  That is the lost Artemis Booster #1, “Big Red”.

"Big Red" carries the Artemis 1E payload to the skies on mission ALS014

Artemis Booster #1, "Big Red".

For a while now, I’ve wanted to name the other rockets…it was just a matter of WHAT to call them.

Starting with the Perseus booster project, Perseus booster # PB01 was given the name “Eagle”, named for the lunar module used in the Apollo 11 mission that took Neil Armstrong and Edwin “Buzz” Aldren to the moon.

Perseus Booster #PB01 "Eagle".

Perseus booster # PB02 (under construction) has already been named “Columbia” — for both the command module used in the  Apollo 11 mission, and in memory of the space shuttle Columbia.


Perseus Booster # PB02 "Columbia" under construction. Not much to see YET!

Artemis rocket names

Artemis booster #03 has been named “Garfield”, after the comic strip character.  It is one of my favorite comic strips.  The color scheme used on the booster (orange and black), reminds me of the comic strip cat.

Artemis Booster #02 has been officially named “Bumble Bee” — it’s yellow and black color scheme has led me to “unofficially” call it that since it was first painted.

Artemis Booster #2 - "Bumble Bee" starting mission ALS017B.

Artemis Booster #04 has not been named yet, but it will be by the time it makes its August 14th launch date.

Artemis Booster #4 - has no name yet..

Keep an eye out on the rocketry blogs, and I will indicate when Booster #4 gets a name!

New launch pad worked flawlessly!

The launch pad and associated electronics all performed flawlessly.  The first launch from the pad was Artemis booster #3,  and the launch was beautiful!

...and LIFTOFF from the new launch pad!

Artemis booster #3 flew missions ALS 029 and 30 from the pad, followed by Artemis booster #3 with missions ALS031 and ALS032.

The Pegasus booster flew two missions from the launch pad, the second being its final mission concluding the experimentation of that new design, and clearing the way for project “Perseus”.  — More on that in a post soon!

Other rockets in my arsenal, but not part of my rocket experiments were flown from the pad too, including my Estes D Region Tomahawk using Aerotech E15w composite propellant motors.

The launch support system performance was textbook, and ready for the next series of launches August 14th!

Launch delayed to Sunday July 25 / launch pad update.

(Cuyahoga Falls, OH July 24, 2010)

Due to high winds, Saturdays launches have been delayed until Sunday.

The purpose of the next three Artemis missions will be to test the new custom built mid power launch pad, and associated electronics.

The electronics include a SLA battery powered pad support unit, and hand held launch controller.

This launch pad is the first step in our bigger project of a customized launch pad system to support future higher power rocketry projects.  Consider it our “getting the feet wet” phase.

We will let you know how it all works out!

Launch Pad update

(July 18th, 2010 – Cuyahoga Falls, OH)

Our new launch pad built for Artemis and Pegasus class booster rockets is nearing completion.  If all goes well, it should be ready to go by July 24th.  This particular pad is a tri-pod design, and is supplied with a beefy 7aH 12 volt gel cell power system to ensure that ALL igniters will function – no questions asked!

This launch pad is also designed with future projects in mind — such as the upcoming Artemis II booster project – which would use clustered motors for flight.

Pictures to come soon!
