7 months..pretty quick for government standards...reference the remote go-pro's for SpaceX.

We knew some support would be "delegated" to ensure Ariane 6 stability...

Germany, Italy, Spain, and Switzerland signed an agreement to use European launch vehicles for their institutional satellites. A win for Arianespace and the Ariane 6 rocket.

Ingenio, built by @AirbusSpace, is a Spanish govt optical reconnaissance satellite. It's part of a system that includes the Paz radar satellite, launched in Feb by @SpaceX.

Details presumably to come. For example, will Germany's commitment include military sats? Will @ASI_spazio never look at another @spaceX or @blueorigin or other non-EU rocket?

Appears to be "localized" government launches to appease their EU political football.

[Blue-Vision]

Yep. This needed to happen for the political "stuff" to get dealt with. Now things can finally move forward full-speed.

[DocM]

Like SLS, A6 one is more a jobs program and govt. feel-good project.

 

They'd be better off supporting European small launcher development with seed money, smallsat launches and regulatory reform then let nature take its course.

 

At one time this would have been hard for startups, but with SpaceX, Rocket Lab etc. providing the strategic roadmap and 3D metal printing for engines...

I dunno. Europe needs it's own launch platform, and A5 is getting long in the tooth; so I can see them doing a big upgrade project to a new platform. As long as it's an actual upgrade.

 

We'll see where it goes. 😊

[DocM]

It's clear A6 is a half-step, Arianespace has admitted it by starting a re-use progeam. They should have done that the day after the first Falcon 9 landed.

[Blue-Vision]

True, but they gotta start somewhere.

NASA’s Hubble Space Telescope Returns to Science Operations

 

NASA’s Hubble Space Telescope returned to normal operations late Friday, Oct. 26, and completed its first science observations on Saturday, Oct. 27 at 2:10 AM EDT. The observations were of the distant, star-forming galaxy DSF2237B-1-IR and were taken in infrared wavelengths with the Wide Field Camera 3 instrument. The return to conducting science comes after successfully recovering a backup gyroscope, or gyro, that had replaced a failed gyro three weeks earlier.

 

A gyro is a device that measures the speed at which the spacecraft is turning, which is necessary to help Hubble turn and lock on to new targets. One of Hubble’s gyros failed on Oct. 5, and the spacecraft’s operations team activated a backup gyro the next day. However, the backup incorrectly returned rotation rates that were far in excess of the actual rates.

 

Last week the operations team commanded Hubble to perform numerous maneuvers, or turns, and switched the gyro between different operational modes, which successfully cleared what was believed to be blockage between components inside the gyro that produced the excessively high rate values. Next, the team monitored and tested the gyro with additional maneuvers to make sure that the gyro was stable. The team then installed additional safeguards on the spacecraft in case the excessive rate values return, although this is not anticipated.

 

On Thursday, the operations team conducted further maneuvers to collect gyro calibration data. On Friday, Hubble performed activities similar to science observations, including rotating to point at different sky locations, and locking on to test targets. The team completed all of these activities without issue.

 

Late Friday, the team began the process to restore the scientific instruments to standard operating status. Hubble successfully completed maneuvers to get on target for the first science observations, and the telescope collected its first science data since Oct. 5. 

 

Hubble is now back in its normal science operations mode with three fully functional gyros.  Originally required to last 15 years, Hubble has now been at the forefront of scientific discovery for more than 28 years. The team expects the telescope will continue to yield amazing discoveries well into the next decade, enabling it to work alongside the James Webb Space Telescope.

Maritime Launch Services Releases Spaceport Animation

The animation, set with local music, guides the user through the various proposed facilities including the integration of payload on the Ukrainian Cyclone 4M rocket.

 

In August the province requested MLS conduct an additional focus report that would “examine potential impacts of the Project on: water resources, soil, air quality, noise flora and fauna, fish and fish habitat, protected areas and parks, dangerous good management, waste management, human health and contingency planning. The EA Administrator will provide you with written terms of reference for the preparation of the focus report within 25 days. Maritime Launch Services Ltd. will have up to one year to submit the required number of hard copies for distribution by the EA Branch, and an electronic copy of the focus report. The EA Branch will notify the public of the release of the focus report for review. There will be a 30-day public review period once the focus report has been released to the public.”

 

MLS is hoping to have the focus report completed and approved in time for a spring ground breaking.

S7 Space to modernize Sea Launch floating spaceport for reusable rocket

 

Quote

MOSCOW, November 7. /TASS/.

 

S7 Space plans to modernize the Sea Launch floating spaceport after switching to the launches of its reusable rocket from it, Company CEO Sergei Sopov told TASS on Wednesday.

 

"The spaceport will be modernized for the new carrier rocket," he said.

 

Today all the equipment on the command vessel and the launching platform has become obsolete, the chief executive said.

 

"It was developed 20 years ago. The platform’s remaining service life is another 25 years. Within this period, the launches of Zenit rockets that have been ordered and are in the process of production and also of our new carrier can be carried out," he said.

 

"The later we make the new carrier, the less time will be left for its operation from the Sea Launch platform," he pointed out.

 

"But, naturally, the spaceport’s service life, like the service life of any complex technical facility, can be considerably extended in case of its major repairs and modernization," the chief executive said.

 

S7 Space is considering several ways of recovering the first stage of its future reusable rocket after launch.

 

"On the list of likely options we have a hypersonic parachute capable of withstanding reentry heat, or special wings. We will make up our mind during the design phase as a result of more accurate calculations and research," he said.

In his opinion at this point it looks like a parachute system will be less costly.

 

"But if this solution is chosen, landing the re-entry stage safely on a small pre-prepared site will be a great problem due to strong side winds," Sopov said.

 

Non-reusable rockets have become uncompetitive and a private company has no chance to survive on the space launch market without reusable vehicles today, he said. 

 

"Without it [the reusable carrier], we simply won’t be able to survive on the commercial market. It is not even funny to compete with reusable and cheap offers entering the market with a non-reusable carrier," he said.

 

In the opinion of S7 Space chief, "a non-reusable rocket is as effective as a non-reusable aircraft."

 

"Creating a non-reusable carrier means not simply marking time but is a road backwards," Sopov said.

 

It is not a matter of the method of recovering the spent rocket stage but largely a matter of "its service life, in the first place, the cycles, the repairability and the labor intensity."

 

"Today all the rocket’s assemblies and systems [in Russia] are non-reusable, i.e. unfit for their repeat use," Sopov said.

Appears the rocket mafia and Boeing may have lit up the phone board....must play the political game...while thinking..."why the hoot am I saying this ?"

 

Because..if true...they just lost the race...outright....well, it really was never a race.

Doesn't change the fact it's on the ground, or in space. SLS is a dinosaur looking for a time & place to rot into crude.
