[Via Satellite 03-10-2016] The question of launch vehicle reusability reigned supreme during Wednesday\u2019s SATELLITE 2016 Conference & Exhibition closing session \u201cGlobal Launch Services \u2014 How the World Fell in Love with Rockets All Over Again,\u201d which featured representatives from Europe\u2019s Arianespace<\/strong>, Japan\u2019s Mitsubishi Heavy Industries<\/strong> (MHI), International Launch Services<\/strong> (ILS), the U.S. subsidiary of Russia\u2019s Khrunichev<\/strong>, and SpaceX<\/strong>. Only SpaceX, which recovered its first rocket first stage in December, has laid out a pointed plan to introduce reusability into its services, with President and COO Gwynne Shotwell saying that the company would like to reuse a recovered rocket first stage within the year.<\/p>\n

\u201cI think we might do [a relaunch of a recovered rocket first stage] this year,\u201d said Shotwell.<\/p>\n

Shotwell said the price of reusing a first stage to launch a satellite could drop costs of launch vehicles. \u201cWe need to recover more and see how many times we can reuse the stage \u2026 but I\u2019d like to see a 30 percent reduction from reuse,\u201d she said. \u201cThe second stage we are not currently recovering, maybe we could figure out some great way to get that back as well.\u201d<\/p>\n

Reusability is a prime way for SpaceX to drive down costs, especially with its aggressive upcoming launch cadence, with Shotwell noting the company is targeting 18 launches total in 2016 and looking to increase that number by 30 to 50 percent year-over-year. \u201cOn top of that, if we do deploy a constellation, that adds quite a bit of launches to our manifest. That\u2019s why we need the rapid and complete reused first stage,\u201d said Shotwell, referencing the company\u2019s early stage plans for a Low Earth Orbit (LEO) constellation. The company is also in the process of opening another launch pad in Cape Canaveral, Fla., which Shotwell said they hope to have up and running by the end of this year, in order to ensure that launch pad availability doesn\u2019t interfere with its aggressive launch schedule. SpaceX has plans to bring a new commercial pad online in Houston, Texas in 2018 as well. Additionally, Shotwell noted that the company is nearly completely vertically integrated for its Falcon 9 launcher and so does not anticipate any hiccups in the supply chain as it ramps up its launch cadence.<\/p>\n

While the SpaceX president notes the company is aiming to recover every first stage, it is unlikely they will be able to do so, citing the recent SES 9 launch in which the company failed to recover the first stage of the Falcon 9. A more realistic lineup for the company includes recovering 75 to 80 percent of first stages from missions to LEO and 50 to 60 percent from missions to Geostationary Transfer Orbit (GTO), she said.<\/p>\n

Other panelists noted that reusability was on their radar, but challenged its practicality.<\/p>\n

\u201cFor the Angara vehicle the main engine was designed to be reused up to five times and I\u2019ve worked on other launch vehicles where reusability was built into the design. The problem is not demonstrating the technical capability of reusability but finding that practical ability to recover it, refurbish it, get it back out onto the launch pad and be able to have the confidence that you are going to provide a reliable launch service time and time again,\u201d said Kirk Pysher, president of ILS.<\/p>\n

Shotwell believes that refurbishing a first stage would be going about it the wrong way.<\/p>\n

\u201cYou can\u2019t take a rocket that was never designed to be reusable and turn it into a reusable rocket, that\u2019s inviting disaster. The aircraft industry doesn\u2019t refurbish their airplanes after every flight \u2014 you can imagine what the turn around at major airports would look like if you had to. So the key is to design a system that you don\u2019t need to refurbish,\u201d Shotwell said, joking that she would rather fly on an aircraft that\u2019s flown a few times. \u201cHopefully our customers get comfortable flying the third or fourth time.\u201d<\/p>\n

Ko Ogasawara, vice president and director of integrated defense and space systems at MHI, noted that reusability has registered on Mitsubishi\u2019s radar as well. The company has been studying the viability of reusable rockets for about 10 years and could potentially introduce the technology into its next launch vehicle design, after introducing its H3 vehicle in 2020, which aims to target the commercial satellite market.<\/p>\n

Other launchers pointed to plans to lower costs on expendable rockets without sacrificing reliability.<\/p>\n

Stephane Israel, chairman and CEO of Arianespace, said the company\u2019s Ariane 6 launch vehicle will provide the same performance of Ariane 5 while reducing cost by 40 to 50 percent.<\/p>\n

\u201cWe have key drivers for that: a new governance, the fact that we are going to produce the same the same booster at a high cadence, so it will reduce the cost, and we have been manufacturing designed to cost and, doing all that; at the end of the day in 2020 we will have a new rocket that is 40 to 50 percent cheaper than Ariane 5,\u201d Israel said. Arianespace is on track to launch eight rockets this year and is targeting 11 to 12 launches per year in the future, according to Israel.<\/p>\n

All launch providers were careful to emphasize, however, that reliability remained the foremost priority.<\/p>\n

\u201cA rocket that fails is a very expensive rocket for my customers, so reliability has always been the main goal,\u201d said Shotwell. \u201cFailure sucks.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
