SpaceX’s next Starlink launch to break Falcon 9 fairing reuse record – Teslarati

Published

 on



SpaceX has revealed that its next Starlink launch will mark a new first for Falcon 9 payload fairing reuse, reaching a milestone that took booster reuse 18 months in less than a year.

Scheduled to lift off no earlier than (NET) 2:19 pm EDT (18:19 UTC) on Thursday, September 17th, the Starlink-12 (v1.0 L12) mission will be SpaceX’s 11th in 2020 alone and 13th overall. If things go according to plan, it could leave SpaceX’s nascent constellation just two or so months away from the beginning of the first public beta tests of Starlink internet service.

Meanwhile, Falcon 9 booster B1058 will be attempting its third launch less than four months after its flight debut, an unprecedented cadence of reuse for SpaceX. Aside from likely ensuring that B1058 becomes the proud holder of SpaceX’s first and second place records for booster turnaround (time between launches), the mission also continues an unexpected trend: the near-extinction of Falcon 9 static fire tests.

SpaceX’s first successful Falcon booster landing happened in December 2015, just a few months shy of five years ago. In March 2017, two years later, SpaceX reused a Falcon 9 booster on an orbital-class launch for the first time in history. Some 21 months after that historic milestone, SpaceX launched the same Falcon 9 booster for the third time, kicking off a relentless series of reusability firsts that continue to be made to this day.

Now, SpaceX says it’s about to launch the same Falcon 9 payload fairing half for the third time in a significant and unexpected first for fairing reuse. Constructed primarily out of a carbon fiber-aluminum honeycomb composite material, Falcon fairings are dramatically more fragile – and reaches much higher altitudes and velocities – than the boosters SpaceX has cut its teeth on recovering and reusing.

Compared to booster reuse, it’s quite the achievement. SpaceX first managed to launch the same Falcon 9 booster three times in December 2018, ~33 months after the first booster reuse. Measured from SpaceX’s first fairing reuse, completed in November 2019 as part of the first Starlink v1.0 launch (Starlink-1), the company will have managed to cross the three-flight fairing reuse barrier less than 11 months later – a full three times faster than SpaceX’s booster reuse program took to achieve the same milestone.

No more static fires?

Meanwhile, SpaceX appears to be turning a major corner on Falcon 9 launch operations. Of all 93 Falcon 9 launches since the rocket’s June 2010 debut, every single one has been preceded by a combined wet dress rehearsal (WDR) and static fire test a few days or weeks prior to liftoff. Effectively simulating a launch 1:1 up to the exact moment before liftoff, SpaceX has used static fires to verify vehicle health and firewall minor quality assurance lapses for as long as it’s been launching rockets.

In a major operational change that has almost flown under the radar, SpaceX appears to have killed the practice of universal prelaunch static fires beginning with Starlink-8 in June 2020. Including Starlink-8, of the seven launches SpaceX has completed in the last three months, just three (GPS III SV03, Starlink-9, and Starlink-10) included Falcon 9 static fire tests prior to liftoff. A step further, two of the four static fire-free launches were for major commercial missions – not retiring risk on SpaceX’s own Starlink launches, in other words.

As of today, Falcon 9 has completed 65 successful launches since the last catastrophic vehicle failure (Amos-6, September 2016) and 74 consecutively-successful launches if Amos-6 (which never lifted off) is excluded. As of 2020, it’s the most reliable US launch vehicle currently in operation, surpassing ULA’s Atlas V several months ago. In fewer words, it’s not actually surprising (in retrospect) that SpaceX has begun to relax its position on static fires – especially considering that there isn’t another launch provider on Earth that static fires rockets before every launch.

More likely than not, SpaceX will continue to static fire Falcon 9 and Heavy boosters at the launch pad before their flight debuts and upon customer request. If launch or post-flight inspection data offer reason(s) for concern, SpaceX may still choose to static fire boosters out of caution. Additionally, SpaceX shows no signs of ending the practice of performing full booster static fires in McGregor, Texas as part of acceptance testing, still leaving it a step beyond traditional rocket manufacturers, which only static fire individual engines.

Regardless, SpaceX’s 13th Starlink launch will be streamed live as usual, with coverage beginning around 15 minutes prior to liftoff.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
