MOSCOW, January 31 - RIA News. Troubleshooting the Fregat upper stage, which is intended to launch British OneWeb communication satellites with the Soyuz launch vehicle from the Kourou cosmodrome, will take a week, so the start is shifted from February 20 to February 27, a source in the space rocket told RIA Novosti.

MOSCOW, January 31. / TASS /. Specialists at the Kourou (French Guiana) cosmodrome eliminated a pinhole in the Fregat upper stage, which is necessary for launching OneWeb satellites into orbit. This was reported TASS source in the rocket and space industry.

"There was a hole in the highway with helium, during inspections pressure began to fall. The specialists at the Kourou cosmodrome cost the standard materials and have already eliminated the hole, and used a simple repair kit. Transportation of the Frigate to Russia will not be necessary," said the agency interlocutor.

According to him, the commission to prepare for the launch of OneWeb satellites, including French experts, gave the go-ahead for the further preparation of the Frigate for the launch.

The source noted that a pinhole in the “Frigate” could have occurred either during the production of the upper stage or during its transportation to the Kourou cosmodrome. "By manufacture it is improbable. Most likely, during transportation", - he told.

The interlocutor of the agency added that the launch of OneWeb satellites was postponed, but there is no exact date for the launch of the Soyuz-ST launch vehicle.

X-ray check

Another source in the industry also confirmed to Tass that the pinhole on the Frigate was eliminated. “The microhole is really patched up, now additional tests are being carried out at the Kourou cosmodrome. Russian experts at Kourou asked their French colleagues to check the Frigate again with an X-ray machine, since Russian specialists do not have such a device at the cosmodrome,” the source said.

He added that before sending to Kura, the upper stage was checked with an X-ray machine at NPO Lavochkina and no micro holes were detected. “Accordingly, this pinhole appeared after the device was taken away from the enterprise. Most likely, during transportation,” said the source.

Roskosmos told TASS that the specialists of NPO Lavochkin, who will fly to Kura on Thursday, upon arrival at the cosmodrome will conduct the full range of necessary work with the upper stage "and report on the results to the customer [of OneWeb], who decides to start."

"Arianespace company has not accepted the offer by the Russian Lavochkin Research and Production Association, which is the producer of the Fregat booster, to repair the unsealed welding seam by putting a bandage on it. We are currently negotiating the possibility to carry out the welding works at the space center, but Arianespace opposes this idea as it believes that repairs should be carried out at the factory", the source said.

MOSCOW, February 5 - RIA News. Experts at the Kourou cosmodrome have begun to test the tightness of the main line with a welded "crack" on the Fregat upper stage, intended to launch the first British OneWeb communication satellites, a source in the rocket and space industry told RIA Novosti on Tuesday.
"Visually, the quality of brewing a leaky seam on the helium supply line was rated by experts as good. Therefore, the cosmodrome began filling the Fregat upper stage with helium in order to check the tightness of the sealed crack," the agency’s source said.

Well, this has been an interesting dance re: quick succession of launch dates...
Feb. 19, to Feb. 26, to possibly March, to Feb. 22.

That's the launch biz! :)

New Date: Tuesday, Feb 26. Four day slip! This is new territory launching so many autonomous spacecraft, and they were factory built. Two firsts, so we are moving carefully in every way. A few days here or there to double check rockets, routines and process is ok by me :)

If these go well we will be set for launching the entire system. Its not just the six satellites but we are constantly reviewing the entire supply chain, manufacturing process repeatability and all the code to make this smooth. Looking good!
