The Russian investigation into the latest Proton rocket has concluded that the failure was caused by a design failure in the rocket’s third stage.
While it is always possible for new design issues to be discovered, I wonder why this problem hadn’t been noticed in the decades prior to 2010, when the Proton began to have repeated failures.
The competition heats up? Virgin Galactic’s replacement SpaceShipTwo has successfully lowered its landing gear for the first time.
I wish them luck, but they will have to do a lot more before I will believe them when they say they are making progress.
The competition heats up: An engine that Russia has developed for its Angara rocket has now been tested and is ready for shipment to the U.S. for use in the first stage of Orbital ATK’s Antares rocket.
This new engine will replace the refurbished Soviet-era engines Antares had been using previously that had caused the October launch failure. Note also that since Antares is not a military rocket, it does not fall under the Congressional ban for Russian engines that limits their use on ULA’s Atlas 5 rocket. As the article notes,
On Jan. 16, 2015, RKK Energia, parent company of NPO Energomash, announced that it had reached an agreement with the American company Orbital Sciences Corporation, OSC, on the export of RD-181 engines for the first stage of the Antares rocket, thus replacing the NK-33 engines previously used on the launcher. The contract, worth around $1 billion, was actually signed and ratified by the Russian government in December 2014. According to the document, a total of 60 RD-181 engines would be delivered to OSC beginning in June 2015.
This deal means that Antares will likely be back in business soon, though it will still be dependent on Russian-built equipment, which carries its own risks. It also means that Orbital ATK will not be able to sell Antares to the U.S. military, limiting its marketability.
A British businessman has purchased a discarded Russian rocket and installed it in his garden as decoration.
Almost 40ft long and weighing five tonne, the rocket was first flown in 1991 after being built by the Russians in collaboration with NASA at a cost $10 million. For ten years it held the record for the fastest ever made-made machine before it was jettisoned as archaic.
Somehow it ended up at a car auction at South Marston where it was spotted by Mr Sweet while checking out vintage motors. Mr Sweet, who runs the Cirencester-based computer company Zycko, said: “I saw it for sale at a car auction and decided to buy it, not really knowing what I was going to do with it.”
I am curious how the rocket had ended up being owned and offered for sale by a UK company that “specializes in car restorations.” I also wonder if this might be a major new profit center for the struggling Russian rocket industry.
The three Russian technicians and their supervisor whose sloppy work caused the spectacular 2013 crash of a Proton rocket immediately after launch have now been indicted on criminal charges and will face trial.
According to investigators, Grishin, Nikolayev and Gudkova in 2011 were tasked with installing the angular rate sensors on the Proton rocket that are responsible for yaw control. “As a result of their violation of technical discipline envisaged by engineering and technological documentation, these sensors were installed incorrectly / at 180 degrees from their correct position/,” Markin said.
The installation error accounted for the vehicle’s wild trajectory, causing its crash and destruction. During the investigation, Grishin and Nikolayev partly admitted their guilt in committing the crime, he said.
In his turn, Nasibulin guided by the fact that over a long time no violations had been found during the installation process and also amid the job cuts withdrew the control operation from a respective list. He did not monitor the process and the sensors were installed without the due control.
Note that they didn’t sabotage anything intentionally. They only did bad work. In the U.S. such incompetence would certainly get them fired, but no one would dream of prosecuting them under these circumstances. It appears that Putin’s government has decided to make them scapegoats and an example to everyone else: Do your work right or else!
Along these lines, Russian government officials have also indicated they are considering imposing fines on manufacturers for any future failures or delays.
Both the criminal indictments and the fines would surely work to prevent further disasters. They will also work very effectively in preventing any risk-taking or innovation from anyone. Who wants to build something new and untested if there is a strong possibility its failure will get you in prison?
Do not expect much creativity from the Russian aerospace industry in the coming years.
Astronauts and ground controllers today successfully used the space station’s robot arm to relocate one of the station’s modules to a different port in order to facilitate the future arrival of two American cargo freighters and two American manned ferries.
The link provides a very detailed explanation of what was done and why.
The Planetary Society’s LightSail solar sail test mission, launched as a secondary payload on last week’s Atlas 5 X-37B launch, has fallen silent because of a software problem.
The communications problem occurred before the mission could achieve its main engineering goal of testing the deployment of the solar sail. They still hope to regain communications, but time is limited as the cubesat is in a low orbit that will decade relatively quickly.
The competition heats up: The Air Force on Tuesday certified SpaceX to permit it to bid and launch military payloads.
This puts big pressure on ULA, which no longer has a monopoly on all military launches. In order to gain contracts they are going to have to compete, lowering their prices to match SpaceX’s.
The inventor of a hoverboard designed to be flown by an individual standing on the board has set a new world record, flying more than 900 feet.
Canadian inventor Catalin Alexandru Duru traveled a distance of 275.9 m (905.2 ft) on a propeller-based hoverboard he created himself. The machine was reportedly designed and built over the course of 12 months. “I wanted to showcase that a stable flight can be achieved on a hoverboard and a human could stand and control with their feet,” Duru is quoted as saying to Guinness World Records, which has recognized the feat.
Video of the flight is below the fold. It appears he essentially scaled up a drone to carry human weight.

In anticipation of the arrival of privately-built manned capsules, NASA will continue the rearrangement of its modules on ISS on Wednesday.
NASA intends to televise the event, if you wish to watch.
Internal disagreements appear to be hampering the investigation into the Progress launch failure in late April.
The investigation had been leaning to pinning the failure on the disintegration of the Soyuz third stage oxygen tank. Others, however, are now claiming that the disintegration itself was caused by an improper separation of Progress from the rocket. The result is that the investigation has delayed the release of its findings.
The competition heats up: The United Arab Emirates (UAE), in conjunction with its goal to send an unmanned probe to Mars, has announced the formation of its own NASA-like space agency.
Reading the long official press announcement at the link above will make you realize that a lot of this is public relations fluff being pushed by the UAE’s sheiks. Stripping that away, what I find left is mostly a program to educate students.
