SpaceX just showed us what every day could be like in spaceflight – Ars Technica

Between Sunday night and Monday night, SpaceX teams in Texas, Florida, and California supervised three Falcon 9 rocket launches and completed a full dress rehearsal ahead of the next flight of the company’s giant Starship launch vehicle.

This was a remarkable sequence of events, even for SpaceX, which has launched a mission at an average rate of once every three days since the start of the year. We’ve reported on this before, but it’s worth reinforcing that no launch provider, commercial or government, has ever operated at this cadence.

SpaceX has previously had rockets on all four of its active launch pads. But what SpaceX accomplished over a 24-hour period was noteworthy. Engineers inside at least four control centers were actively overseeing spacecraft and rocket operations simultaneously.

The sprawl of SpaceX

On Sunday night at the Starbase facility in South Texas, teams loaded more than 10 million pounds of methane and liquid oxygen propellants into the nearly 400-foot-tall (121-meter) Starship rocket slated to lift off as soon as this month on the third full-scale test flight of SpaceX’s next-generation launcher.

This was likely the final major test before SpaceX launches the third Starship test flight. The countdown rehearsal of the fully stacked rocket ended as planned at T-minus 10 seconds, just before the booster’s Raptor engines were ignited; SpaceX then drained the vehicle of propellant. SpaceX previously test-fired the Super Heavy booster and Starship upper stage separately.

The schedule for the next Starship launch hinges on approval from the Federal Aviation Administration, which is reviewing SpaceX’s actions to correct the malfunctions that occurred on the second Starship test flight in November. Last week, the FAA announced it closed its investigation into the second Starship test flight, which was largely successful in demonstrating significant progress on SpaceX’s privately funded rocket program. But the test flight ended with explosions of the Super Heavy booster and Starship upper stage, prompting an FAA investigation.

On the next Starship flight, SpaceX wants to perform some early-stage testing of the in-space refueling technology it will need for later Starship flights, such as missions to the Moon for NASA.

At the same time SpaceX’s team in Texas managed the Starship countdown rehearsal, another group of engineers and technicians on Florida’s Space Coast stepped through a Falcon 9 launch countdown Sunday night. Three NASA astronauts and one Russian cosmonaut strapped into their seats on SpaceX’s Crew Dragon Endeavour spacecraft on top of the Falcon 9 rocket, then waited for liftoff from Launch Complex 39A at NASA’s Kennedy Space Center at 10:53 pm EST Sunday (03:53 UTC Monday).

The Falcon 9 launch of NASA’s Crew-8 mission Sunday night was the first of three Falcon 9 launches over the next 20 hours. Next in line was a launch at 5:05 pm EST (2205 UTC) Monday from Vandenberg Space Force Base in California with 53 small payloads on SpaceX’s 10th Transporter rideshare mission. The customer payloads on this Falcon 9 launch included MethaneSAT, an $88 million satellite funded primarily by philanthropic donations to monitor methane greenhouse gas missions around the world.

Then, less than two hours later, at 6:56 pm EST (2356 UTC), a Falcon 9 rocket took off from SpaceX’s most active launch pad at Cape Canaveral Space Force Station in Florida. This mission delivered 23 more Starlink broadband satellites into orbit for SpaceX’s commercial Internet network. At 1 hour and 51 minutes, this was the shortest time separation to date between two SpaceX launches.

All three Falcon 9 launches ended with landings of the rockets’ first stage boosters.

While controllers at Starbase, Cape Canaveral, and Vandenberg looked after these three Falcon 9 launches, SpaceX engineers at the company’s headquarters near Los Angeles tracked the performance and progress of the Crew Dragon Endeavour spacecraft on its way to the International Space Station, where it docked early Tuesday. Next week, another SpaceX capsule, Crew Dragon Endurance, will depart the station to bring a different four-person crew back to Earth.

SpaceX, which now has more than 13,000 employees, pulled off a similar rapid-fire launch cadence in mid-February with three Falcon 9 launches in approximately 23 hours, but this time included the additional complexity of operating a Dragon crew capsule en route to the ISS, plus the Starship countdown in Texas. While all this was going on, a handful of ground controllers also monitored the health of the Dragon spacecraft currently docked at the space station.

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.
