Bilan 2011 des lancements vu par les Russes

29.12.2011 / 00:05 In 2011, the space-faring nations met 84 launch of space carriers


In 2011, around the world started 84 of the launch vehicle (LV), the aim of which was injected into Earth orbit a payload of various kinds. Of these, 77 launches were successful, three - partially successful, four - the emergency.
The number of launches in 2011 the carrier over the previous year increased by 10 units (13.5%) and almost reached the 2000 level, when held 85 launches. Over the last decade is the highest rate.
As in recent years a leader in the number of launches rocket was Russia - 32 start-up (38.09% of the global total). If we take into account two launches "Soyuz-ST" from Kourou, "recorded" for the company Arianespace, the buyer of missiles, and launch rocket "Zenit-3SL" with sea launch platform Odyssey, referred to the company Sea Launch, which has recently been plays a major role RSC "Energia", through its subsidiary, this number increases to 35 starts (41.67% of the world total).
disturbs only a relatively high level alarm and a partially successful launches of Russian rocket - 5 (15.62% and 14.28%, respectively, for different methods of calculation).
For the first time in the history of the world space to the second largest number of rockets launched out China - 19 starts (22.35%), including one emergency. For China, this figure is a "record." Never before in the Middle Kingdom did not run so much space carriers.
United States for the first time in the history of space "slipped" into third place - 18 starts (21.17%), including one emergency.
The fourth place is occupied by a consortium Arianespace with seven runs. But, as noted above, actually two launches should be assigned to Russia.
fifth or sixth places are shared by India and Japan. The assets of these countries on three space launch.
seventh and eighth place is shared by Iran and the company Sea Launch - one start. But the "sea spaceport" is included in this rating with the above disclaimer.
More from the analysis of the starting activity of cosmic powers will be available on the pages of the "Encyclopedia" Space " from 16 am Moscow time on 31 December 2011.

12.30.2011 / 00:05 in 2011 was put into orbit a spacecraft 131


As a result of launch vehicles in 2011, was launched into orbit 131 spacecraft. That's 13 satellites more than in 2010.
This includes two American nanosatellite Nanosail-D2 and Fastrac-2, separated at the beginning of last year running in 2010 and satellite Fastsat Fastrac-1, respectively.
Seven satellites were lost as a result of Accidents carriers.
As the number of implemented carrier rockets, Russia holds the leadership and the number placed in orbit satellites - 52 (39.69% of all the countries of the running). But 28 spacecraft (53.84%) - a foreign satellite, launched on commercial contracts. If we add to this the number of satellites placed in space by means of "Unions", launched from Kourou, as well as start-up program Sea Launch, the number of satellites launched by Russia, is increased to 61, while the share of commercial payload increases to 60.66 %.
Value, which is not very good.
The American missiles have put into orbit 28 satellites (21.37%), Chinese - 21 satellite (16.03%).
Launchers Ariane-5 Arianespace company brought in Space 9 spacecraft (6 , 87%).
With Indian carriers launched eight satellites (6.1%).
Three satellites (2.29%) were launched by Japanese rocket.
One spacecraft (0.76%) delivered into orbit Iran's satellite launch vehicle.
More about running in 2011, satellites will be available on the pages of the "Encyclopedia" Space " from 16 am Moscow time on 31 December 2011. - KI

En fait ce qui est essentiel dans un lancement : c'est la CHARGE UTILE qui représente son unique justification, en dehors des vols d'essais du dit lanceur évidemment.
Grosso modo le rôle du lanceur peut se réduire comme simple vecteur entièrement consommable et non comme une fin en soi !
Logiquement, la nationalité d'un lancement devrait être celle de son commanditaire payant mais ça risque de compliquer les statistiques astronautiques où tout était bien tranché durant les premières décennies.

Alors Fobos-Grunt, lancement russe ou ukrainien :scratch:

Les Russes sont très très forts... en comm ! :D
Quand ils disent "28 satellites commerciaux", ils comptent tous les petits Cubesats et autres microsatellites lancés par Dniepr, ainsi que les lancements Soyouz en Guyane et Soyouz par STARSEM...

Exocet a écrit:On pourrait également faire un décompte en valeur ou en "tonnage", ça pourrait être intéressant.

les ukrainiens : - russe bien sur !
les russes : - ukrainien bien sur !

Le lancement en lui-même s'est bien passé (succès de la Zenit 2), c'est la sonde qui a défailli ensuite. Donc les Ukrainiens auraient torts de ne pas revendiquer ce tir. ;)

Russia hints at foul play in its space failures
January 10, 2012

The head of Russia's beleaguered space programme hinted on Tuesday that foreign powers may be behind the string of failures that struck his agency in the past year.

Roskosmos chief Vladimir Popovkin told the Izvestia daily he could not understand why several launches went awry at precisely the moment the spacecraft were travelling through areas invisible to Russian radar.

"It is unclear why our setbacks often occur when the vessels are travelling through what for Russia is the 'dark' side of the Earth -- in areas where we do not see the craft and do not receive its telemetry readings,"he said.

"I do not want to blame anyone, but today there are some very powerful countermeasures that can be used against spacecraft whose use we cannot exclude," Popovkin told the daily.

One of Russia's most high-profile recent failures involved the November launch of a Mars probe called Phobos-Grunt that got stuck in a low Earth orbit and whose fragments are now expected to crash back down on Sunday.

Popovkin said there was "no clarity" as to why the 13.5-tonne probe's booster rocket failed to fire on schedule. But he admitted the mission was risky to begin with because it involved an underfunded project whose original designs went back to Soviet times.

"If we did not manage to launch it in the window open in 2011 for a Mars mission, we would have had to simply throw it away, writing off a loss of five billion rubles ($160 million)," he said.

Popovkin was named the head of Russia's space agency in April after its previous chief was sacked in the wake of an embarrassing loss of three navigation satellites during launch.

Yet the problems only multiplied under his watch as Russia lost several more satellites and also saw its Progress cargo ship experience its first-ever failure on a mission to the International Space Station.

The Mars mission setback was followed last month by the loss of the Meridian communications satellite. Its fragments crashed into the Novosibirsk region of central Siberia and hit a house ironically located on Cosmonaut Street. No injuries were reported but the 50-centimetre (20-inch) fragment blew a hole in the home's roof.
