Hunk of burning junk by SpaceX

SpaceX  is delivering a 3.500 kg satellite, KoreaSat 5A, to geostationary transfer orbit (GTO). SpaceX will be attempting to land the first stage back on their drone ship Of Course I still Love you (OCISLY) about 8 minutes after launch 630 km (430nM) downrange in the Atlantic Ocean.

SpaceX is targeting the launch of Koreasat-5A from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center, Florida on Monday, October 30 at 3:34 p.m. EDT, or 19:34​ UTC. The satellite will be deployed approximately 36 minutes after liftoff.

Following stage separation, Falcon 9’s first stage will attempt a landing on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.

Something fueltank related got damaged during landing and the engine bay caught fire

Landing of the first stage was also successful, albeit resulting in a “toasty” engine section, although fire hoses on the drone ship will have put out the flames shortly after landing.

I have no special knowledge of what SpaceX is using as fire suppressant, but typically a MIL-spec fluoroprotein-based aqueous film-forming firefighting foams are used to fight petroleum-based fires. They can be mixed just as well with seawater as freshwater, which makes them a good choice for firefighting at sea.

The payload Koreasat 5A (Mugunghwa 5A)

Thales Alenia Space announced in May 2014 that it has signed a contract with the Korean satellite service operator KT Sat, subsidiary of KT Corporation, to build two telecommunications satellites, Koreasat-7 and Koreasat-5A, winning the contract against an international field of competitors. The two satellites will provide Internet access, multimedia, broadcasting and fixed communications services.

As program prime contractor, Thales Alenia Space is in charge of the design, production, testing and On Ground Delivery (OGD) of the satellites. It will also take charge of the launch campaigns, the launch and early operations phase (LEOP) and in-orbit tests (IOT).

Built on the Upgraded Spacebus-4000B2 platform from Thales Alenia Space, Koreasat-5A will carry 36 Ku-band transponders. Koreasat-5A will cover Korea, Japan, Indochina and the Middle East. The satellite will weigh about 3,500 kg at launch and will offer payload power of about 7 kW. Koreasat-5A will be positioned at 113° East. Source

The Koreasat 5A and Koreasat 7 telecommunications satellites constructed by Thales Alenia Space will include the largest spacecraft parts ever made in Europe using a 3D laser beam printing technique called the “powder bed additive manufacturing process” in the Concept Laser Xline 1000R 3D printer, that is melting aluminum powder into telemetry and command antenna supports structures measuring some 45cm by 40cm by 21cm.

The parts for the two satellites are identical and were made in the same batch by the same machine belonging to Poly-Shape, a French partner of Thales Alenia Space. Each satellite has two antenna parts, featuring an innovative bio-design, passed the vibration acceptance tests, and demonstrated perfectly reproducible dynamic behavior.

Using 3D printing technology on this type of part offers a number of advantages, including 22% weight savings, a decrease in the production schedule of around one or two months, about 30% cost savings, and higher performance. Antenna support of this type is already in orbit on the TurkmenAlem satellite also built by Thales Alenia Space in April 2015.

Kerbal on a personal note

It would be nice if Tim Dodd had a Kerbal version of a Falcon 9 flight from launch to drone ship landing of stage one. The fairings from separation through descent and landing on the ocean or on the fairing catching boat. The second stage until SES-2 with explanations depending on mission profile Polar, ISS, LEO or GTO and deployment of payloads including their own journeys to their targets. There should be Kerbal videos about all scenarios.

Flying into the night is such a sight

SpaceX is targeting the launch of a Falcon 9 with a reused booster B1031-2 with EchoStar 105/SES-11 from Launch Complex 39A - LC-39A at NASA’s Kennedy Space Center, Florida. The two-hour launch window opens on Wednesday, October 11 at 6:53 p.m. EDT, or 22:53​ UTC. The satellite will be deployed approximately 36 minutes after liftoff.

There was a successful landing on ASDS “Of Course I Still Love You” about T+08:33 after liftoff from LC-39A some kilometer downrange. Landing of the first stage B1031-2 was successful, but resulted in a fire from a leak somewhere in the engine section; the onboard fire hoses put out the flames shortly after landing.

This is the third time SpaceX will be reflying a booster. This flight-proven booster B1031-2 has flown once before for mission CRS-10 in February 2017. This is the 15th launch for SpaceX this year and 43rd launch of the Falcon 9 overall.

The Payload

SES-11/EchoStar 105 is a shared geostationary communications satellite operated by SES S.A. and EchoStar. It’s designed and manufactured by Airbus Defence and Space. It has a mass of 5,200 kilograms (11,500 lb) and has a design life of at least 15 years.

The spacecraft had been ready to beam television programming and video services across the Americas for SES and EchoStar. The launch vehicle has placed the satellite into a high-altitude supersynchronous transfer orbit.

On 11 October 2017, a flight-proven (refurbished) SpaceX Falcon 9 rocket launched the SES-11 satellite to the geostationary orbital position of 105.0° West. The launch was originally set for late 2016 but suffered a year-long delay because of SpaceX's Amos-6 September 2016 Falcon 9 explosion.

SES-11 was built by Airbus Defence and Space and is a dual mission satellite, with 24 Ku-band transponders marketed by EchoStar as EchoStar 105 to replace capacity on SES' AMC-15 satellite, and 24 C-band transponders marketed by SES as SES-11 for replacement capacity for AMC-18 delivering video, especially HD and UHD, to the United States, Mexico and the Caribbean. Following positioning at 105.0° West and in-orbit testing, SES-11 was declared fully operational on 29 November 2017.

Chain gang

Working on a chain gang. B1031-2 “I’ll be back” is back in Port Canaveral. John Krauss.

This picture tells us that 4 tripods hold the weight of the Falcon 9 rocket in its launch hold down clamps just under the landing leg hinges, and that 8 heavy duty safety chains are welded to the drone ships deck plates and tightened fast to prevent lateral movements.

The Man on deck indicates that there is 5-6 feet to the bottom rim of the engine bells of the Falcon 9 Merlin 1D+ engines. The scale of the Falcon 9 rocket is impressive. It literally is a “tower” of human rocket engineering.
