SpaceX’s Starship Prototype Nails Another Hop Test! Bring on Orbital Flights! – Universe Today

Published

 on


SpaceX has done it again! Earlier today (Thurs. Sept. 3rd), the company completed a second hop test with a Starship prototype. This time, it was the sixth iteration (SN6) that successfully made the 150-meter (~500 foot) flight at their launch facility near Boca Chica, Texas. This latest test has further validated the Starship design and the Raptor engine, two systems which Musk hopes will someday take humans to the Moon, to Mars, and beyond!

This test comes less than a month after SpaceX made a similar hop with their SN5 prototype (which took place on August 4th). On that occasion, the Starship managed to reach 150 m and then land on an adjacent pad without incident, though it didn’t quite stick the landing and damage one of its legs in the process. Together, these tests have put SpaceX in good standing to begin conducting high-altitude (and eventually, orbital) test flights.

Originally, the company was hoping to make this second attempt during an otherwise jam-packed Sunday. Aside from SN6 blasting off from Boca Chica, SpaceX was also scheduled to conduct two launches from Cape Canaveral – another batch of Starlink satellites (V1 L11) and Argentina’s SAOCOM 1B Earth observation satellite. In anticipation of the launch, Cameron County issued a road closure notice for up to three days.

This notice specified Sunday (Aug. 30th) as the primary date – from 08:00 am to 08:00 pm local time (07:00 am – 07:00 pm EDT; 06:00 am – 06:00 pm PDT) – with backup opportunities for Monday and Tuesday from 08:00 am to 08:00 pm. Unfortunately, the flight test was pushed back to Thursday, most likely due to prevailing winds around the launch site, at around 12:45 pm local time (10:45 am PDT; 01:45 pm EDT).

These two hop tests are the latest in a string of successes for SpaceX, which is a welcome change of pace given their previous string of failures. After completing tests with the miniature prototype, the Starship Hopper, the company lost four full-scale prototypes in a row – Mk1, SN1, and SN3, and SN4. The first three prototypes blew up during cryogenic loa testings, whereas the SN4 passed this test, but exploded during a static fire test.

But of course, these losses were anticipated because of SpaceX’s rapid-prototyping and “test to failure” process. By building one iteration of the Starship after another, then pushing it to its limits, SpaceX has been able to accumulate massive volumes of data that have helped them improve the overall design. With the lessons that they have learned, the company is now on the verge of several major milestones.

This includes the assembly of the SN7 and SN8 prototypes, which (according to a previous statement made by Musk) are likely to be making their own 150-meter hop tests in the near future. Once that is finished, SpaceX will be attempting a high-altitude hop test, which will involve a prototype equipped with three Raptor engines and body flaps attempting to hop 20 km (12.4 mi).

During a phone interview on Tuesday, as part of the 2020 Virtual Humans to Mars Summit, Musk shared that his company would begin constructing the first stage booster (the Super Heavy) this week. He also said that the design might be updated once again to feature fewer engines – 28 instead of 31 this time. “That’s still a lot of engines,” he said. “We’ll up cranking up the thrust on those engines.”

As for when the high-altitude flight could take place, he indicated that it could happen “probably next year.” He also cautioned that there will still be a steep learning curve:

“The first ones might not work. This is uncharted territory. Nobody’s ever made a fully reusable orbital rocket … and then having something twice the size of a Saturn V (the rocket that astronauts to the moon) that’s also fully reusable… that’s really something else, that’s profound. That’s the gateway to the galaxy or at least the solar system.”

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.
