New release of OpenRocket 15.03 . Tube Fin aficionados rejoice because it includes experimental support for tube fins.

Changes include:

Support for scripting in simulation extensions
Experimental support for tube fins
Custom default mach number
Improved preferences UI
Fin fillet masses (no aero effects though)
Custom icons for different mass types (altimeter, hardware, etc)
Mass in the tool tip on the component tree.
And numerous little bugs and annoyances fixed

Today’s test. Turn it up loud!

It’s nice to see a spacecraft in the “not in low earth orbit” context again. Great photo of second stage delivering the spacecraft to it’s parking orbit for a spectacular view of the whole earth.

Soft Landing at sea.

Elon Musk tweeted:
“Rocket soft landed in the ocean within 10m of target & nicely vertical! High probability of good droneship landing in non-stormy weather.”

DARPA has a concept program called ALASA(Airborne Launch Assist Space Access) that uses small jets to assist in launching small payloads into orbit.

“DARPA’s Airborne Launch Assist Space Access program (ALASA) seeks to propel 100-pound satellites into low Earth orbit (LEO) within 24 hours of call-up, all for less than $1 million per launch. The current ALASA design envisions launching a low-cost, expendable launch vehicle from conventional aircraft. Serving as a reusable first stage, the plane would fly to high altitude and release the launch vehicle, which would carry the payload to the desired location. The program is moving ahead with rigorous testing of new technologies that one day could enable revolutionary satellite launch systems that provide more affordable, routine and reliable access to space.” – DARPA
