Progeny Mk6 Block II Flight 1

The debut flight of the powerful Block II version of the Mk6 sets out to see if its design proves capable of reaching space and possibly exploring a new region if it can pass through the hazardous radiation found above the planet

Progeny Mk6 Block I Flight 5 Analysis

After sending 4 rockets on southward trajectories to see if we could find an end to the hazardous radiation region discovered ~350km above the planet, the final flight in that series recorded no radiation increase above the baseline 0.01rad/hr found outside the atmosphere. To determine whether the same could be said north of the equator, this flight sent up earlier in the week was planned to mirror the third launch of the Mk6 Block I that found an increase, but not to peak levels of 10rad/hr. If we could record similar measurements on this flight, we could determine the field is fairly uniform around the equator, otherwise we could find significantly more or less to tell us the field is asymmetrical.

The Flight

Because the rocket needed to launch northwards, the launch base had to be moved out into the field north of the runway so the rocket would not risk damaging the new service towers constructed on the launch pad for Ascension rockets. This presented some issues that slightly delayed the launch as cables run out that far to carry power and data were not able to handle the distance initially, and relays/repeaters had to be installed. Although we’ve had rockets launch from this area before, the power requirements of the Progeny Mk2.1 were much less and no data was needed other than a simple electrical signal to trigger the launch.

Progeny Mk6 Block I Flight 5

Exploring the hazardous radiation zone to the north of the equator opposite a previous flight, although it completed its primary objective the rocket failed to be recovered due to an operational oversight

Progeny Mk6 Block I Flight 4 Analysis

The final launch in our latest campaign has been to space and back. This ends our initial exploration of the hazardous radiation zone discovered above the planet, a report on which will be published separately after more data collection and analysis from future Progeny launches. We’ll cover that at the end as usual, for now let’s take a look at this recent flight in detail.

The Flight

Once again the only major change to the ascent profile of the rocket was to launch even further to the south, lifting off from the launch base at precisely 09:02:00.06 local time to head 150° SSE after a delay due to cloud cover. 67.2kN of thrust from the lower 0.625m booster pushed the rocket at 4Gs and climbed to 68.9kN before beginning to taper off after just 3 seconds to ensure the rocket did not speed through MaxQ too fast, topping out with a dynamic pressure of 77.104kPa passing through 5km traveling at 550m/s at L+18s. Staging occurred at L+35s, 14.9km ASL, after the lower booster expired and was pushed away by the decoupler, its fins shredding via det-cord 1 second later to spoil its lift and send it crashing downrange into the Kerblantic .

Coasting for 7.62 seconds before the nose fell 1.5°, the AFCS kicked off the second stage booster at 18.5km to boost at 14.7kN with a TWR of 3.1. Trajectory remained stable throughout the burn until the booster expired at L+54s, when the stage was dumped and the third booster ignited one second later at full thrust to continue the push for space.

Progeny Mk6 Block I Flight 4

Although threatened by weather on both launch and landing the latest flight for the Mk6-I was a complete success despite some technical issues during the freefall back to Kerbin. It also may have discovered the edge of the hazardous radiation region
