گراڤيتي-1 المهمة 1 إطلاق 11 يناير 2024

گراڤيتي-1 (Gravity-1 ؛ الصينية: 引力一号) هي solid-propellant expendable medium-lift launch vehicle designed, manufactured and launched by Chinese aerospace company Orienspace. يمكنها حمل حمولة تصل إلى 6.5 طن إلى مدار أرضي منخفض أو 4.2 طن إلى مدار متزامن مع الشمس، مما يُمكنها من نشر كوكبات ساتلية واسعة النطاق. يبلغ ارتفاع الصاروخ 30 متر، وزن الإقلاع هو 400 طن، بقوة دفع عند الإطلاق قدرها 600 طن،[1] and a fairing diameter of 4.2 meters.[2] Its maiden launch was conducted from a منصة إطلاق بحري in the Yellow Sea on January 11, 2024, breaking records as both the world's most powerful solid-fuel carrier rocket and China's most powerful commercial launch vehicle to date.[3] Large pieces of debris were seen during the launch, which carried 3 Yunyao-1 meteorological satellites built by the Shanghai Academy of Spaceflight Technology, as part of the planned 90-satellite Yunyao constellation.[3][2]

Gravity-1 consists of seven solid rocket motors (SRB) in total. The first four side-mounted SRBs are ignited on the ground, while three core boosters are air-lit in sequence. The launch cost for Gravity-1 is around US$39 million. Gravity-1 has a quick-response-time of only five hours between manufacturing completion and launch. Orienspace has signed contracts for the launch of more than one hundred satellites.[4] Gravity-1 is the most powerful rocket consisting of entirely solid-rocket motors.[5] Due to the huge solid rocket motors, large plumes of smoke were produced during the launch.
