AI Thread Summary
Copenhagen Suborbitals is set for a sea launch of its SMARAGD hybrid rockets on July 27, with the first launch, SMARAGD-1, aiming for an altitude of 8 km to test stage separation. If successful, the second launch, SMARAGD-2, will attempt to reach 20-25 km with a full fuel load. The launch will be live-streamed, though video quality may vary due to signal issues from offshore. Following an initial failure due to ignition signal problems, preparations for the second attempt are proceeding smoothly, with all systems operational. Updates and debrief information will be shared as they become available.

According to the latest status and weather reports, the danish amateur rocket group Copenhagen Suborbitals [1] is still go for a sea launch of one or both of its two-stage SMARAGD hybrid rockets in the expected launch window Friday, July 27 at 08 to 12 UTC [2].

The first launch will be SMARAGD-1, where the second stage will be loaded with a reduced amount of fuel to test stage separation, is expected reach an altitude of around 8 km. If the launch of SMARAGD-1 is successful, SMARAGD-2 will be launched with a full fuel load for an expected maximum altitude of 20-25 km. A nice video presentation of the SMARAGD rocket made by the CS group can be found on youtube [3].

The event is expected to be covered by a live transmission on livestream [4] and I will post relevant news to this thread as the event proceeds.

The sea launch platform, Sputnik, and its support vessels are in position in the launch area. The preparations for the first launch are proceeding according to plan.

Interested can watch live video feed on http://www.livestream.com/csscph with audio commentary in English at http://www.livestream.com/cssaarhus

Video feeds may only work intermittently due to signals having to go over radio link from 30 km off shore. The video feed from the platform may be shaking a bit due to the platforms diesel engine (expected to be turned off right before launch).

First launch attempt failed due to a problem with the ignition signal, apparently from interference from the voice VHF link and misaligned antennas.

Second launch attempt under way.

Update: Launch area clear and ready for launch. Payload electronics and camera have been recharged and is operational. Final go/no-go has been completed. Launch in progress. Launch confirmed. Payload section of SMARAGD has been located and is being retrieved. The crew is preparing to return to port Nexø.

I will post relevant debrief information here when it becomes available from the group.

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
