The Havørn rocket is 2.85m long and 0.09m in diameter and is powered by an ‘M-class’ KNER solid rocket motor. The rocket will launch from the group’s purpose-built offshore launch platform in the North Sea.
Check out the group’s website, Facebook and YouTube for more information.
Video Caption: Long time since we posted a video, but we are still going strong. This video shows some of the work we have done in 2017 and until now.
Bugger sums this up!

Video Caption: This was the 2nd test firing of the 12 x 44″ KNSB static test fire motor for the Sugar Shot to Space project. The first firing was using two 12 x 20″ propellant grains each weighing 132 pounds for a total propellant weight of 264 pounds. This test was using three 12 X 13″ propellant grains, each containing 85 pounds of KNSB sugar propellant.
A nice overview video of USCRPL’s Fathom II launch from back in March showcasing prep, launch/flight, and recovery. The team set a record for student built rockets.
Video Caption: On March 3rd, 2017, University of Southern California Rocket Propulsion Lab launched Fathom II, a sub-scale model of its space-shot vehicle in Spaceport America, New Mexico. Fathom II reached 144,00 ft at apogee, taking the record for highest student rocket by almost 50,000 feet.
In what is possibly a first, the MIT Rocket team have successfully tested a fully 3D printed solid rocket motor. The motor which included everything bar the propellant was printed from Nylon.
Be interesting to know the cost, let’s say vs a hobby motor of the equivalent size.
Check out the video below and read the full write-up here.
Video Caption: Using Markforged Onyx Nylon a 2 piece, completely 3D printed rocket motor was fired for the first time by MIT Rocket Team on April 21.
Without the generous support of Markforged this project would not have been possible.
Team Icarus, a team under the SDSU Rocket Project, recently tested their in-house designed and built solid rocket motor. The motor is intended to launch a boosted dart to 100,000ft.
This particular motor was a 4″ dia (101.2mm) composite case, burning an APCP propellant blend, producing a chamber pressure of 760psi. The burn time was 5sec.
You can follow Team Icarus on Facebook to stay up to date on this project.
12″ diameter (304.8mm), 2 Bates grains, 260lbs (117kg) of propellant!
Be interesting to know the thrust and chamber pressures achieved in this test, they seem to have figured out any grain cracking issues that could arise and over pressurize the motor, looking forward to seeing more tests of this size in the future!
