launch of China’s Kuaizhou-11 fails,after march booster soars to space

China confirmed its Kuaizhou-11 rocket failed after launching today (July 10) from the Jiuquan Satellite Launch Center in northwest China. The cause for failure is currently being evaluated.

This failure comes just one day after the country launched another rocket type successfully from the Xichang Satellite Launch Center in southwest Sichuan China.

A press release from state media source Xinhua stated that a “malfunction” happened after the liftoff at 12:17 p.m. Beijing time (12:17 a.m. EDT or 0417 GMT). “The specific cause of the failure is under further analysis and investigation,” Xinhua added.

Video footage of the launch, which is available via a delayed stream, shows that the rocket worked well in the first minute of the launch and the first and second stage separations appeared to be successful, according to SpaceNews.com.

Kuaizhou-11 (also known as KZ-11) was attempting to launch on its first mission after several delays in development and was carrying two satellites into space. The rocket was first developed in 2015 and its first launch was initially scheduled for 2018, according to NASASpaceflight.com.

There were two satellites on board the failed rocket. CentiSpace-1 S2 (also referred to as Xiangrikui 2 or Weili-1-02 in media reports) was part of a satellite series for low-Earth orbit navigation. Jilin-1 Gaofen-02E (also called BilibiliSat) is a remote sensing satellite intended for commercial applications, specifically for managing geological disasters and natural resources.

KZ-11 was developed by the China Aerospace Science and Technology Corp. and commercialized by the China Space Sanjiang Group Corporation (Expace), according to NASASpaceflight.com. The rocket can send up a payload with a mass of up to to 220 pounds (100 kilograms) to sun-synchronous orbit in a medium-altitude Earth orbit that allows for consistent lighting conditions below. Alternatively, it can send a payload of up to 3,300 pounds (1500 kg) to low-Earth orbit. A KZ-11 represents one of several commercial efforts in China to supplement the country’s traditional reliance on government-funded launches, an analyst told SpaceNews.com.

While this launch, which was the 19th launch from China in 2020, resulted in failure, the country’s 18th launch of the year which took place the day before successfully lifted the APSTAR-6D telecommunications satellite into space aboard the veteran Long March 3D rocket type. This launch was captured in footage by state media source China Central Television (CCTV). It blasted off at 8:11 p.m. Beijing time (8:11 a.m. EDT or 1211 GMT) on Thursday (July 9).

APSTAR-6D is expected to last about 15 years in space in geostationary orbit, as part of a broadband satellite communications system serving the Asia-Pacific region, CCTV added in a news report. The satellite is designed to provide high-speed communications with a capacity of about 50 gigabytes per second.

The APSTAR-6D satellite was developed by the China Academy of Space Technology, a subsidiary of China Aerospace Science and Technology Corp. The satellite was purchased by APT Mobile SatCom Limited in 2016.

DFH-4E’s launch comes after two earlier failures of the platform, SpaceNews added. A ChinaSat-18 spacecraft power failure occurred immediately after launch in August 2019 and a second attempt in April this year saw the Long March 3B rocket and the Nusantara-2 Indonesian satellite destroyed.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine

Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.

When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.

While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress. (Also read: Bhagyashree swears by this super easy exercise for instant leg pain relief and better mobility.

Why recovery is key for muscle growth

According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.

Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.

Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.

Role of overtraining syndrome and deload weeks

Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.

Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.

Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
