Is this broadcast anywhere else on the arc?

I`m having problems getting 23.5 due to the wind, can get 13e 19.2e upto now but its too windy to try anything else as I can only move the dish when the wind dies down or I might aswell be peein in the wind lol

Everything was a few clicks west of where it`s ment to be on the motor but I just cant get it to lock on 23.5

He's right, the rocket is to be taken off the pad.

Still, there is Globalstar 2 in a couple of days time

An avionics module has been deemed faulty. launch delayed at least 25 days as the rocket has to be destacked.

LIVE: ILS Proton-M launches with SES-4
February 14th, 2012

International Launch Services (ILS) have launched their first Proton-M rocket of the year on Tuesday. Lift off came at 19:36 GMT from the Baikonur Cosmodrome in Kazakhstan, with the Proton’s Briz-M Upper Stage tasked with deploying the large telecommunications satellite after nine hours of flight.

Proton Launch:

The Proton booster tasked with the launch of the satellite was 4.1 m (13.5 ft) in diameter along its second and third stages, with a first stage diameter of 7.4 m (24.3 ft). Overall height of the three stages of the Proton booster is 42.3 m (138.8 ft).

The first stage consists of a central tank containing the oxidizer surrounded by six outboard fuel tanks. Each fuel tank also carries one of the six RD-276 engines that provide first stage power. Total first stage vacuum-rated level thrust is 11.0 MN (2,500,000 lbf).

Of a conventional cylindrical design, the second stage is powered by three RD-0210 engines plus one RD-0211 engine and develops a vacuum thrust of 2.4 MN (540,000 lbf).

Powered by one RD-0213 engine, the third stage develops thrust of 583 kN (131,000 lbf), and a four-nozzle vernier engine that produces thrust of 31 kN (7,000 lbf). Guidance, navigation, and control of the Proton M during operation of the first three stages is carried out by a triple redundant closed-loop digital avionics system mounted in the Proton’s third stage.

The Breeze-M upper stage is the Phase III variant, a recent upgrade which utilizes two new high-pressure tanks (80 liters) to replace six smaller tanks, along with the relocation of command instruments towards the centre – in order to mitigate shock loads when the additional propellant tank is being jettisoned.

The launch was set to take place at the end of 2011, prior to a problem associated with the avionics system of the launch vehicle’s Breeze M upper stage forcing a delay into 2012, ahead of further slips to the February 14 launch date. The initial delay was called after Khrunichev engineers at the launch site received an anomalous telemetry reading on the Breeze M upper stage during preflight testing.

The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, lifted off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the SES-4 satellite on board.

The first three stages of the Proton used a standard ascent profile to place the orbital unit (Breeze M upper stage and the SES-4 satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission manoeuvres to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geostationary transfer orbit.

Separation of the SES-4 satellite is scheduled to occur approximately 9 hours, 12 minutes after liftoff.

A beautiful on time lift off - and with clear skies we managed to follow the launch right through to first stage burn out and separation.

BAIKONUR COSMODROME, Kazakhstan, February 15, 2012– International Launch Services (ILS), a leading launch services provider for the global commercial satellite industry, successfully carried the SES-4 satellite into geostationary transfer orbit today on an ILS Proton for SES of Luxembourg (Euronext Paris and Luxembourg Stock Exchange: SESG). This was the 20th SES satellite launched on ILS Proton and the 70th ILS Proton launch overall.

The ILS Proton Breeze M launched from Pad 39 at the Cosmodrome at 1:36 a.m. today local time (2:36 p.m. EST, 20:36 GMT on February 14). After a 9 hour, 12-minute mission, the Breeze M successfully released the SES-4 satellite into geostationary transfer orbit.

This was the 373rd launch for Proton since its inaugural flight in 1965. The Proton Breeze M launch vehicle was developed and built by Khrunichev State Research and Production Space Center of Moscow, one of the pillars of the space industry and the majority shareholder in ILS
SES-4 is the largest satellite in SES’s fleet, weighing 6.18 metric tons to be located at 338°east; the largest neighborhood in the Atlantic. Built on the flight-proven Space Systems/Loral 1300 platform, SES-4 will be a hybrid satellite featuring 52 high powered C-band coverage and incremental global capacity for video distribution, government and VSAT services. The satellite’s 72 Ku-band payload will provide enhanced capacity across three continents, with coverage in Europe, the Middle East, Africa, Western Africa and Latin America.

ILS President, Frank McKenna said, “It is always thrilling to achieve milestones in our business but even more so when it is with a longtime customer, such as SES. With the ILS Proton launch of SES-4 this marks our 20th SES satellite launched on ILS Proton and the 50th satellite in the SES fleet. We are honored to be entrusted with launching the powerful SES-4 satellite and look forward to performing on all of our upcoming ILS Proton missions for SES,” said ILS President, Frank McKenna.
“Once again, ILS Proton has come through for SES, enabling the expansion of our business into emerging markets with the launch of SES-4. This is the 50th satellite in SES’s fleet and the third launch attempt by the powerful Proton launch vehicle proved to be a total success. We are thankful for the hard work and diligence of the collective teams of ILS, Khrunichev, SES and Space Systems/Loral on this mission for this successful launch,” said SES President and CEO, Romain Bausch.
