SpaceX Starship struts its stack to show it has the right stuff

How tall is Starship and superheavy?

Super Heavy alone stands 230 feet (70 meters) tall and Starship SN4 added another 165 feet (50 m) of height. Together they stood a whopping 395 feet tall (120 m), taller than NASA's massive Saturn V moon rocket, which was 363 feet tall (110 m). "Dream come true," Musk wrote on Twitter of the stacked Starship. space.comSpaceX stacks Starship atop massive booster for 1st time to make the world's tallest rocket

Biggest ever rocket is assembled briefly in Texas

The vehicle's two segments - an upper-stage called Starship and a booster called Super Heavy - were connected together at the firm's Starbase R&D facility in Boca Chica, Texas.

Standing roughly 120m (400ft) in height, the SpaceX rocket dwarfs any previous launch system.

When it eventually lifts off, it will produce about twice the thrust of the vehicles that sent men to the Moon.

The main engines on Apollo's famous Saturn V rockets delivered some 35 meganewtons (nearly 8 million pounds of force) off the pad. The new SpaceX Super Heavy booster should achieve around 70 meganewtons.

A massive crane was needed to join the two segments together. They were held in position for an hour before then being separated again.

SpaceX still has weeks to months of testing ahead of it to prepare for the inaugural flight.

This will see the booster hurl the Starship into space for a once-around-the-Earth trip, which will end with a disposal "landing" in waters off the Hawaiian islands in the Pacific. The Super Heavy will be ditched in the Gulf of Mexico.

Ultimately, though, SpaceX wants both segments of future vehicles to make controlled touchdowns, on land or on sea platforms, so they can be re-used.

Company CEO, Elon Musk, says the Starship system, once fully developed, will be more than capable of taking humans to the Moon and Mars.

It could also ferry people quickly around the globe. Putting satellites in orbit is another obvious application.

The American space agency, Nasa, has already contracted SpaceX to produce a version of the Starship upper-stage that can land astronauts near the lunar south pole this decade.

Friday's milestone follows months of breathtaking activity in Boca Chica.

Engineers have built a succession of prototypes at Starbase. These have helped the design team understand the best way to manufacture the huge stainless steel craft. And by launching some of the Starship iterations on high-altitude hops, SpaceX technicians have also gained invaluable flight experience.

The government agency is currently conducting an environmental review that will invite at some point a 30-day public consultation. So, the maiden orbital outing is still some way off. But Mr Musk is very keen that it should happen well before the end of the year.

He described seeing the brief mating of the segments on Friday as a "dream come true".

The most powerful rocket currently in operation is the Falcon Heavy, also built by SpaceX. This produces 23 meganewtons of thrust at launch.

Simone Biles' Olympic career may be over but experts say her influence will transcend gymnastics

Observer 07 August, 2021 - 05:00am

The superstar left on her terms, after stepping away during the competition to focus on her mental health.

Although she is leaving the door open for a 2024 return, if Tokyo was her curtain call, then the questions turn to what is her legacy and what does the sport’s most recognizable gymnast do for a second act?

Experts say Biles, who is tied for the Olympic record for most medals won by an American gymnast, will transcend the sport, pushing for mental health and wellness, and ushering it past the last remnants of its darkest period — the Larry Nassar scandal.

Nassar, the USA Gymnastics team’s former doctor, was accused of sexually assaulting more than 120 girls. He pleaded guilty to sexually abusing 10 minors in Michigan court in 2018 and is serving up to 175 years in prison.

She now has the opportunity to continue speaking out against sexual assault and promoting any other social banners she chooses to carry.

“I would say Simone’s legacy is actually far greater reaching than medal count, and her beginning to help facilitate the change of culture in our sport,” said Bob Neat, director of communications for the National Gymnastics Association.

He said Biles, who has 32 Olympic and world medals, will represent a shift toward advocating for more safety and better treatment of athletes and coaches.

Neat predicted she’ll become more outspoken and take on a bigger stage.

In Tokyo, Biles withdrew from the team all-around, the individual all-around, the vault, floor exercise and uneven bar events after struggling early on.

She cited the mental and emotional toll of competing in the Games as reasons for backing out.

"Physically, I feel good. I'm in shape," she told Hoda Kotb on NBC's "TODAY" show following her exit. "Emotionally, it varies on the time and moment. Coming to the Olympics and being head star isn't an easy feat."

Her decision drew harsh criticism from many who said she had quit on her team, and praise from mental health supporters who backed Biles, the most decorated gymnast in history, for knowing when to take time for herself.

Biles, a Black woman dominating a majority white sport, said she felt a lot of pressure heading into the international competition.

It’s “like the weight of the world on your shoulders," she said. It’s a "little bit too heavy to carry," but it helps to take a step back and focus on her mental health, she said.

Derrin Moore, founder of the Atlanta-based advocacy group Brown Girls Do Gymnastics, said Biles’ legacy will forever be tied to her decision in Tokyo.

“I feel before, her legacy was going to be about her ability and skill and showing brown girls you can be who you want to be,” Moore said. “But now that she bowed out of a lot of the Olympics, I think her legacy will be around mental health. As tough as she is, and as talented as she is, she still knew when she needed to take a break. I think that’s huge for her.”

Biles wasn’t afraid to push the envelope or be the greatest gymnast, which opens the door for more Black and brown girls to follow in her footsteps, she said.

Biles’ influence on the sport will likely grow through World Champions Centre, the Houston-area training facility her parents founded, where she will most likely mold the next wave of world-class gymnasts.

“Simone was one of the first people to open up a gym and coach the kids the way she wanted to be coached. Simone was always talented, but she always wanted to do more,” said Ashley Umberger, a 2001 USA national team gymnastics member.

Biles can lean on her experience to train future Olympic gymnasts, she said.

“You understand the training and mentality because you were the athlete. And once the athlete becomes the coach, it’s like another realm,” Umberger, who owns North Stars Gymnastics in New Jersey, said. “She’s going to have the feel of going to the Olympics, she’s going to have the experience of what it’s like to be an Olympic champion and what it feels like to make a mistake and come back.”

World Champions Centre has already had big successes.

“I lived in a world where everything [was] strict, strict, strict,” Chiles told NBC Sports in May. “They’ve (World Champions) given me so much encouragement. I didn’t get that too much in the past.”

Chiles then credited Biles with bringing about a culture change.

“The fact that the gym is Black-owned makes it a beacon for Black elite gymnasts,” Moore said. “That’s not by happenstance. That’s a Simone thing. It’s going to become the blueprint.”

As great of an athlete as Biles is, some believe her spotlight may dim a little in the years ahead.

“There’s always somebody new that’s going to come and maybe make new achievements,” said Tori Ford, a women’s gymnastics coach at Discover Gymnastics in Houston. “She won’t be forgotten about all the way.”

It wouldn’t be the first time a well-known Olympic gymnast has faded. Dominique Dawes and Shannon Miller, who both won gold medals as part of the 1996 “Magnificent Seven” team, were once household names who aren’t in the public eye as much anymore.

“I don’t think it’s possible to forget Simone Biles,” Umberger said.

Neat reiterated that Biles’ impact will eventually surpass her accomplishments and steering the next generation of athletes.

“Her role isn’t going to be just coaching in the gym, but leading a cultural shift of protecting the wellness of athletes and coaches. Her biggest role coming out of the Olympic Games is helping to shift the culture. That’s her legacy. She is the person to do it. She is the individual that understands it better than anybody.”
