Here is a question for you guys and a new article about the launches from t his space company back in december 2019:

What is a back-to-back rocket launch ?
I tried googling it so far it seems two pads being used, but maybe it also means these rockets return to earth ?
That's the part I am trying to figure out, did these rockets return to eart h and if so were they touched by employees from this space company in wuhan where supposedly the corona virus orginated.

Two solid-fueled Kuaizhou 1A rockets fired into orbit from the same spacepo rt in northern China Saturday, demonstrating a further advance in China? ??s aim for a quick-response, on-call satellite launch capability.
The back-to-back Kuaizhou 1A missions both lifted off from the Taiyuan spac e center in northern China?s Shanxi province, using separate road-m obile transporters as launch pads.
The rockets successfully carried a total of seven small satellites into orb it for Earth-imaging, ship tracking, and experimental communications missio ns, according to China?s state-run Xinhua news agency.
Saturday?s rapid-fire launches from Taiyuan marked the sixth and se venth flights of Kuaizhou 1A rockets since then launch vehicle model debute d in 2017, and the fourth and fifth Kuaizhou 1A flights this year. Last mon th, Chinese teams performed two Kuaizhou 1A launches in a four-day period a t the Jiuquan launch base in northwestern China.
All seven of the Kuaizhou 1A satellite delivery flights to date have been s uccessful.
Powered by three solid-fueled booster stages and a liquid-fueled orbital in jection engine, the Kuaizhou 1A rocket is one of several new Chinese smalls at launchers. It?s managed by Expace, a commercially-oriented subsi diary of the China Aerospace Science and Industry Corp., the biggest Chines e state-backed aerospace contractor. The light-class Kuaizhou 1A rocket is capable of injecting 440 pounds (200 kilograms) of payload to a 435-mile-hi gh (700-kilometer) orbit.
Kuaizhou means ?speedy vessel? in Chinese, a name indicativ e of its purpose as a satellite launcher that can be readied for liftoff in a short time period. The rocket ? likely derived from Chinese ball istic missile technology ? launches from a road-mobile transporter.
The launches Saturday were the first Kuaizhou 1A flights from Taiyuan. All previous launches by the solid-fueled booster originated from Jiuquan.
The first Kuaizhou 1A flight Saturday lifted off from Taiyuan at 0255 GMT S aturday (10:55 a.m. Beijing time; 9:55 p.m. EST Friday) with the Jilin 1 Ga ofen 02B Earth observation satellite, according to Xinhua.
The Jilin 1 Gaofen 02B spacecraft joins a fleet of commercial Earth-imaging stations owned by Chang Guang Satellite Technology Co. Ltd. The new satell ite is the 15th spacecraft launched in the Jilin 1 fleet since 2015, and wi ll be capable of collecting imagery with a resolution of better than 2.5 fe et (75 centimeters).
The Kuaizhou 1A rocket delivered the Jilin 1 Gaofen 02B satellite into a 33
2-mile-high (535-kilometer) orbit inclined 97.5 degrees to the equator.
Less than six hours after the first launch of the day from Taiyuan, another Kuaizhou 1A booster fired off a different launch pad at 0852 GMT (4:52 p.m . Beijing time; 3:52 a.m. EST) with six small satellites on-board. The second Kuaizhou 1A launch Saturday from the Taiyuan space center delive red six small satellites into orbit. Credit: Weibo
The six payloads aboard the second Kuaizhou 1A flight Saturday were deploye d in orbit around 310 miles (500 kilometers) above Earth, on a track inclin ed 97.4 degrees to the equator.
Two privately-developed satellites for Beijing-based HEAD Aerospace launche d on the second Kuaizhou 1A flight Saturday will provide environmental moni toring, asset supervision, emergency communication, and ship and aircraft t racking services. The 100-pound (45-kilogram) HEAD 2A and 2B satellites are the first craft in HEAD Aerospace?s Skywalker constellation.
The second Kuaizhou 1A launch also delivered the Spacety 16 and 17 small sa tellites to orbit for Spacety Co. Ltd. The Spacety payloads are ?me dium-resolution micro-nano remote sensing satellites that are mainly used f or disaster prevention, maritime applications, agricultural remote sensing and polar environment monitoring,? according to Xinhua.
Two experimental data relay nanosatellites named Tianqi 4A and 4B were also launched for Guodian Gaoke, another Beijing-based company, Xinhua said. "
Bye for now, Skybuck.
