SpaceX puts 60 Starlink satellites in orbit with first rocket launch of the year [photos] – Teslarati

Published

SpaceX has kicked off a record-breaking 2020 launch manifest with a spectacular combination of Starlink satellites and a Falcon 9 rocket, the first of perhaps two dozen such launches planned this year alone.

Falcon 9 booster B1049 supported the mission, becoming the second SpaceX rocket ever to complete four launches and landings after B1048 did it first in November 2019. Starlink-2’s Falcon 9 booster is now safely aboard drone ship Of Course I Still Love You and beginning the 600 km (375 mi) journey back to Port Canaveral, Florida, where it will likely be processed and turned around for a fifth launch in the near future.

Teslarati photographer Richard Angle was on-site to capture the event and caught a number of spectacular photos of SpaceX’s Starlink-2 launch, ranging from an excellent visualization of the rocket’s trajectory to a close-up view highlighting the fury of Falcon 9’s nine Merlin 1D engines seconds after liftoff.

Falcon 9 Block 5 boosters are loaded with some 520 metric tons (1.2 million lb) of liquid oxygen, refined kerosene (RP-1), helium, and nitrogen. At full throttle, the nine Merlin 1D engines that power each Falcon booster can produce more than 7600 kN (1.7 million lbf) of thrust, equivalent to more than 60 737 passenger jets chained together. At the same time, every one of those nine Merlin 1D engines likely consumes more than 270 kg (600 lb) of liquid oxygen and kerosene every second, with all nine engines combining to burn the equivalent of one and a half Tesla Model 3s worth of propellant per second.

A step further, the 1.5 Teslas of propellant Falcon 9 boosters burn each second exits the nozzles of their nine Merlin 1D engines traveling almost 3 kilometers per second (1.9 miles per second) – more than 35 times faster than the fastest hurricane windspeeds every recorded. In simple terms, the exhausts of even tiny orbital-class rockets create a spectacularly violent and unearthly environment in the seconds immediately following liftoff, exaggerated by the ground and pad hardware reflecting all that energy and fury.

And Falcon 9 (let alone Falcon Heavy) is no tiny rocket. While it’s still extremely difficult to get a good sense of scale while looking at launch photos, it’s safe to say that photos of Falcon 9’s nine Merlin 1D engines shortly after launch undeniably capture at least a small sense of the sheer heat, fury, and stress experienced by SpaceX’s orbital launch pads. One of the most obvious features are giant clouds backlit by the rocket’s own engines, produced as a side effect of the common use of water deluge systems to protect launch pads and keep launch vehicles from damaging themselves.

In the handful seconds the rocket is near the pad, swimming pools worth of water are almost instantaneously vaporized by into superheated steam clouds by its exhaust and then violently buffeted by the shockwaves and vibrations they produce. In simple terms, the sound alone – let alone the heat or debris kicked up by the exhaust – would likely kill or at least severely injure an unprotected human observer standing nearby, while the heat would probably incinerate immediate bystanders.

Regardless of the pedantry of observing rocket launches up close and really personal, January 6th’s Starlink launch is the first of as many as 36 launches SpaceX has planned in 2020 – some two dozen of which could end up being dedicated Starlink missions. SpaceX’s next two Starlink launches – Starlink-3 and -4 – are already scheduled to lift off as early as later this month.

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

Published

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.
