Yesterday, SpaceX founder and CEO Elon Musk announced the preliminary results ove the investigation on the mishap to the Falcon 9 rocket which led to its destruction just over two minutes after its June 28, 2015 launch. The culprit appears to be a component of the hardware rocket, one of the support struts of the rocket’s second stage’s liquid oxygen tank that handled a pressure much lower than that it was certified for.

A flittle while ago the SpaceX Dragon spacecraft blasted off on a Falcon 9 rocket from Cape Canaveral in its CRS-7 (Cargo Resupply Service 7) mission, also referred to as SPX-7. It was supposed to be the seventh mission that sent the Dragon spacecraft to the International Space Station with various a cargo. Unfortunately a couple of minutes after launch something went wrong, causing the destruction of the rocket and the Dragon.

Airbus Defence and Space, a subsidiary of the aerospace corporation Airbus Group that builds the Ariane 5 launchers for ESA and Arianespace, has presented the project of the Adeline (ADvanced Expendable Launcher with INnovative engine Economy) system to reuse part of rockets’ first stage. It also presented plans to build space tugs to be placed in orbit, where they’ll deliver newly launched satellites into their required orbit.

Roscosmos, the Russian space agency, announced the results of the investigation on the failure of the mission of the Progress M-27M cargo spacecraft. The problem was found to be in the separation system between the spacecraft and the third stage of the Soyuz 2-1a rocket used to launch it. A new Progress mission to bringh supplies to the International Space Station could be scheduled for early July, probably using a Soyuz-U rocket, the version used until recently.

Roscosmos, the Russian space agency, announced the results of the investigation on the problem that caused the failure of the mission of the Proton-M rocket on May 16, 2015. The fault was detected in the turbopump rotor of the rocket’s third stage engine which resulted in an instability in the engine that caused the emergency shutdown. According to the investigation, it’s a design flaw and recommendations were issued to correct it.
