    selvaarchi: "Do I put the ESA launch as a partial failure as it did not insert the satellites in the correct orbit? Suggestions please."

    Tough question.

    - I would guess most launches occur with anomalies of some type.
    - The payload ended up in the right orbit. Was its lifetime affected by use of etra propellant? I think this was the case with a Chinese satellite last year.
    - If it had been a Chinese launch, we might not have been aware of any anomaly whatsoever.

    That is why Trebuchet suggested the category "partial failure" be introduced when we discussed it before.

    How about Zuma? Doesn't seem to have been a success. Unless that's what THEY want us to think....

    These are geostationary sats, they don't need fuel once they reach their spot. So if it can still reach its orbit, which it can, it will reach its intended lifespan. So...I'd say it's a close call but a success. There is no influence on the mission. A very different situation from the LEO satellites for which the "partial failure" category was created.

    SES-14 will reach the geostationary orbit four weeks later than originally planned, and the satellite is expected to meet the designed life time.

    Till we get confirmation that it is "lost" we got to go with SpaceX's story that it was a textbook launch.

    I am putting it as partial failure as the rocket did not do what it was supposed to do and put the satellites in a wrong orbit.

    I think geostationary satellites drift a bit and need fuel to keep them precisely on station. Using fuel to get there will reduce lifespan. Citation needed, of course.

    ETA: Citation.

    But...but...but I just gave a citation that the lifespan will not be influenced for this particular case. I have a booboo now.

    The 13th launch for this year is from USA. It was SpaceX 2nd launch this year.

    For future reference, the time of launch will be taken as the UTC time. This will stop the confusion of the different time zones. For example this was launched on the 1st of February in Malaysia.

    https://www.nasaspaceflight.com/2018...lcon-9-launch/

    SpaceX launched Luxembourg’s first military spacecraft on Wednesday, with a flight-proven Falcon 9 carrying the GovSat-1 communications satellite into geosynchronous transfer orbit. Liftoff from Cape Canaveral’s Space Launch Complex 40 was at the start of a 121-minute window that opened at 16:25 Eastern Time (21:25 UTC). Amazingly, the booster survived a water landing, despite the return not involving the drone ship.

    The 14th launch this year and the 1st in February is by Russia.

    https://www.nasaspaceflight.com/2018...-1a-kanopus-v/

    Russia made its first launch of 2018 Thursday, using a Soyuz-2-1a/Fregat-M rocket to deliver a pair of Kanopus-V satellites to orbit. Soyuz lifted off from the Vostochny Cosmodrome in Eastern Russia at 11:07 Yakutsk Time (02:07 UTC), beginning a five-and-a-half-hour mission that will also include the deployment of nine secondary payloads.

    The 15th launch this year and the 2nd in February is by China.

    https://www.nasaspaceflight.com/2018...-investigator/

    A Long March 2D has conducted the sixth Chinese launch of 2018, with the lofting of the Zhangheng-1 spacecraft, a new research satellite for the observation of ionospheric precursors of earthquakes. The launch took place at 07:51 UTC on Friday from the 94 Launch Platform at the LC43 Launch Complex from the Jiuquan Satellite Launch Center (JSLC). An additional six small satellites rode along with the primary payload.

    The Orbital Debris newsletter also carries a list of launches, perhaps you can use it for double checking, if you want.

    Wow Japan just launched a satellite into orbit with the smallest rocket in the world.

    The 16th launch this year and the 3rd in February is by Japan.

    http://spaceflight101.com/japan-ss-5...aunch-success/

    A beefed-up sounding rocket-turned-orbital-launch-vehicle zoomed into the skies over Japan’s Kyushu Island on Saturday in a bid to become the smallest launch vehicle to successfully achieve orbit one year after its inaugural test flight crashed into the Pacific Ocean.

    The SS-520-5 vehicle shot up from its rail launcher at 5:03 UTC and JAXA confirmed the rocket successfully achieved orbit less than four and a half minutes after liftoff – one of the fastest space shots ever carried out.

    Saturday’s launch placed a tiny, three-Kilogram satellite into orbit and demonstrated the feasibility of launching CubeSats one at a time using a dedicated Nano Satellite Launch Vehicle – an as of yet largely unexplored area of the market.

    Well done SpaceX. That was awesome - congratulations.

    The 17th launch this year and the 4th in February is by USA. It was the 3rd launch by SpaceX this year.

    https://www.nasaspaceflight.com/2018...ration-launch/

    The long-awaited and much anticipated heavy lift rocket from SpaceX has become most powerful and capable rocket presently in service around the world after its debut launch on its maiden voyage from LC-39A at the Kennedy Space Center on Tuesday, 6 February. The historic launch set sail near the end of its available window at 15:45 pm Eastern.

    The 18th launch this year and the 5th in February is by China.

    https://www.nasaspaceflight.com/2018...3-meo-3-meo-4/

    Monday saw the seventh orbital launch of the year by China, with a Long March-3B/YZ-1 orbiting a new pair of navigation satellites. The launch took place just after 05:00 UTC from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province. It took over four hours to complete the mission.

    The 19th launch this year and the 6th in February is by Russia.

    https://www.nasaspaceflight.com/2018...iss-rendezous/

    The Russian Progress resupply ship MS-08 launched at the second attempt atop the Soyuz 2-1A rocket at 08:13 UTC on Tuesday. Docking will occur two days later. The original launch was to result in docking at the International Space Station (ISS) just 3.5 hours later. However, it was scrubbed with just seconds remaining in the countdown at the Baikonur Cosmodrome.

    They are targeting between 40 and 45 launches this year. From the NASASPACEFLIGHT report on the BeiDou launch they have another two this month. This give you some idea of their ambition this year.

    http://www.xinhuanet.com/english/201..._136974997.htm

    The Long March-3B rocket launched Monday from the Xichang Satellite Launch Center in southwest China's Sichuan Province marked the seventh successful mission of the Long March rocket series since the beginning of 2018.

    The year 2018 will be an ambitious year for China's space program, with the largest number of Long March rocket launches.

    The 20th launch this year and the 7th in February is by USA. It was the 4th launch by SpaceX this year.

    Mr. Steven however did not manage to net the fairing halve.

    https://www.nasaspaceflight.com/2018...o-new-fairing/

    SpaceX has launched with the debuting of an upgraded payload fairing for the Falcon 9 rocket during Spain’s Paz satellite lofting from Vandenberg Air Force Base on Thursday. The launch, scrubbed on Wednesday due to Upper Level Winds, also carried the first demonstration satellites for SpaceX’s own satellite internet constellation. Launch occurred at an instantaneous launch opportunity at 06:17 Pacific Time (14:17 UTC).
