The results from Monday\u2019s hotfire test will help designers confirm the rocket\u2019s performance matches expectations.<\/p>\n<p>\u201cNo anomalies were seen and the performance met expectations, though full analysis will take several months,\u201d the European Space Agency said in a statement.<\/p>\n<p>Burning a&nbsp;pre-packed rubber-like solid propellant mixture called HTPB, the P120C will be used as the first stage of Europe\u2019s new Vega-C rocket set to enter service late next year. The Vega-C is an upgraded, higher-performing version of the Vega launch vehicle, which has logged 11 straight successful flights since its debut in February 2012.<\/p>\n<p>Europe\u2019s next-generation Ariane 6 rocket, scheduled for a maiden test flight in July 2020, will fly with two or four P120C rocket motors as strap-on boosters, allowing engineers to adjust the launcher\u2019s lift capability depending on the weight and destination of its payload.<\/p>\n<figure id=\"attachment_33407\" aria-describedby=\"caption-attachment-33407\" style=\"width: 678px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-large wp-image-33407\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/First_hot_firing_of_P120C_motor_for_Vega-C_and_Ariane_6-678x479.jpg\" alt=\"\" width=\"678\" height=\"479\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/First_hot_firing_of_P120C_motor_for_Vega-C_and_Ariane_6-678x479.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/First_hot_firing_of_P120C_motor_for_Vega-C_and_Ariane_6-300x212.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/First_hot_firing_of_P120C_motor_for_Vega-C_and_Ariane_6-768x543.jpg 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/First_hot_firing_of_P120C_motor_for_Vega-C_and_Ariane_6.jpg 1200w\" sizes=\"(max-width: 678px) 100vw, 678px\"><figcaption id=\"caption-attachment-33407\" class=\"wp-caption-text\">The P120C solid rocket motor ignites Monday on a test stand in French Guiana.

The P120C\u2019s carbon fiber casing is manufactured by Avio in Colleferro, Italy, near Rome, and its nozzle is produced at Ariane Group\u2019s Le Haillan site near Bordeaux, France.<\/p>\n<p>Ariane Group is a 50-50 joint venture between Airbus and Safran, and the principal owner of the launch services company Arianespace.<\/p>\n<p>The major components were shipped to French Guiana, and the developmental motor fired Monday was assembled and filled with solid propellant at a fueling plant at the Guiana Space Center, then rolled out to the test stand on rails last month.<\/p>\n<p>\u201cThe success of the P120C static firing test is a key milestone on the Vega-C and Ariane 6 development programs in view of the launchers\u2019 maiden flights schedule for 2019 and 2020, respectively,\u201d said Giulio Ranzo, Avio\u2019s chief executive.<\/p>\n<p>In a statement, Ranzo called the test-firing \u201ca great technological achievement for its unique performance, the result of radical innovation combined with over 30 years of experience in solid propulsion through cooperation between Avio and Ariane Group.\u201d<\/p>\n<figure id=\"attachment_33408\" aria-describedby=\"caption-attachment-33408\" style=\"width: 678px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-33408\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/P120C_rocket_motor_transfer_to_test_stand_at_Europe_s_Spaceport_node_full_image_2-678x480.jpg\" alt=\"\" width=\"678\" height=\"480\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/P120C_rocket_motor_transfer_to_test_stand_at_Europe_s_Spaceport_node_full_image_2-678x480.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/P120C_rocket_motor_transfer_to_test_stand_at_Europe_s_Spaceport_node_full_image_2-300x213.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/P120C_rocket_motor_transfer_to_test_stand_at_Europe_s_Spaceport_node_full_image_2.jpg 700w\" sizes=\"(max-width: 678px) 100vw, 678px\"><figcaption id=\"caption-attachment-33408\" class=\"wp-caption-text\">The P120C development motor was transferred to its test stand in French Guiana in June.

It contains nearly twice the propellant carried by the P80 rocket motor, and provides an increase in thrust of roughly 50 percent over the currently-flying P80.<\/p>\n<p>By comparison, the Ariane 5 rocket\u2019s twin strap-on solid-fueled boosters each produce around 1.2 million pounds of thrust at sea level, more than the P120C. But the Ariane 5\u2019s boosters come in three heavier steel pieces, or segments, and are more expensive to manufacture.<\/p>\n<p>High-power five-segment solid rocket boosters designed to fly on NASA\u2019s Space Launch System generate more than 3 million pounds of thrust.<\/p>\n<p>Two qualification test-firings of the P120C rocket motor are planned at the end of this year and in 2019 before the inaugural flight of the Vega-C rocket.<\/p>\n<p>The Vega-C will be the first vehicle to incorporate the P120C solid rocket motor. The uprated version of Europe\u2019s Vega launcher will be able to loft up to 4,850 pounds (2.2 metric tons) to a 435-mile-high (700-kilometer) polar orbit, an improvement over the Vega\u2019s current lift capability of around 3,300 pounds (1.5 metric tons) to the same orbit, according to the European Space Agency.<\/p>\n<p>Officials intend for a launch of the upgraded Vega-C rocket to cost no more than the baseline Vega booster, which has achieved success in luring contracts for launching small Earth observation satellites. Arianespace is also eyeing the rideshare launch market for future Vega flights.<\/p>\n<p>The Vega-C will also debut an enlarged second stage motor, called the Zefiro 40, which was successfully test-fired in Sardinia for the first time in March.<\/p>\n<figure id=\"attachment_33409\" aria-describedby=\"caption-attachment-33409\" style=\"width: 678px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-33409\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/Artist_s_view_of_Ariane_6_and_Vega-C_node_full_image_2-678x559.jpg\" alt=\"\" width=\"678\" height=\"559\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/Artist_s_view_of_Ariane_6_and_Vega-C_node_full_image_2-678x559.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/Artist_s_view_of_Ariane_6_and_Vega-C_node_full_image_2-300x247.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/07\/Artist_s_view_of_Ariane_6_and_Vega-C_node_full_image_2.jpg 700w\" sizes=\"auto, (max-width: 678px) 100vw, 678px\"><figcaption id=\"caption-attachment-33409\" class=\"wp-caption-text\">Artist\u2019s illustration of the Ariane 6 (left) and Vega-C (right) launch vehicles.

A test version of the Ariane 6\u2019s Vulcain 2.1 main engine, based on the Ariane 5\u2019s Vulcain 2 powerplant, completed its first hotfire demonstration on a test stand in Germany in January.<\/p>\n<p>The development of both rockets is funded in public-private partnerships between the European Space Agency and industry, mainly Ariane Group and Avio, with the objective to provide Europe with an independent strategic launch capability, while attracting continued commercial launch business for Arianespace.<\/p>\n<p>The Vega-C and Ariane 6 rockets will blast off in French Guiana from launch pads a few miles away from the test stand used for Monday\u2019s P120C hotfire.<\/p>\n<p>With the projected launch rates of the Ariane 6 and Vega-C rockets, Avio says it will produce up to 35 P120C motor casings per year at its Colleferro manufacturing facility. European officials say the shared solid motor production line will help bring down Ariane 6 and Vega-C launch costs as Arianespace faces stiff competition from private launch companies like SpaceX.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>European engineers test-fired the world\u2019s most powerful present-day single-segment solid rocket booster Monday in French Guiana, clearing a major development hurdle for the Vega-C and Ariane 6 launchers set for debuts in 2019 and 2020.
