SpaceX Crew Dragon: astronauts reveal big benefit over space shuttle – Inverse

Published

Doug Hurley and Bob Behnken are the only two people who know what it’s like to fly on a SpaceX rocket. On Friday, the pair revealed some more details about how it feels, and why the Falcon 9’s design changes things.

Hurley and Behnken flew on the first crewed flight of the SpaceX Crew Dragon. The human-carrying capsule, designed to help NASA send astronauts to and from the International Space Station, was launched by a Falcon 9 rocket on May 30 from Kennedy Space Center’s Launch Complex 39A in Florida. It was a momentous occasion: after NASA’s space shuttle program ended in 2011, the agency had to send astronauts to the station with the help of Russian agency Roscosmos. SpaceX’s crewed flight helped kickstart a new era for NASA missions, one that brings these flights a little clsoer to home.

In an interview with Spaceflight Now, Hurley described the launch as feeling “totally different than shuttle,” adding that “it was smooth. It got a little rougher.” Hurley, who was in charge of launching, landing and recovery for the Crew Dragon mission, also flew on the space shuttle’s final mission.

Behnken agreed, saying that he was “surprised a little bit at how smooth things were off the pad.” He told the publication:

“The space shuttle was a pretty rough ride heading into orbit with the solid rocket boosters, and our expectation was, as we continued with the flight into second stage, that things would basically get a lot smoother than the space shuttle did. But Dragon was huffing and puffing all the way into orbit. It was not quite the same ride the smooth ride as the space shuttle was up to MECO (main engine cutoff). A little bit less Gs, but a little bit more alive is probably the best way I would describe it.”

The main difference, as noted by Hurley, is the propellant in use. The space shuttle used two solid rocket boosters for flight, designed to send the vehicle up to 150,000 feet. Each booster weighs 1.3 million pounds, with a motor that uses 1.1 million pounds of propellant. These worked with the main engines, so the boosters provided the thrust for the first two minutes of flight before giving way to the hydrogen-powered main engines.

Using solid fuel, unlike liquid, makes it easier to store and makes the development process cheaper. But the New York Times noted that solid fuel burns more “like a giant firecracker,” as opposed to the easier-to-control liquid fuel as used on the Falcon 9.

This is perhaps why the launch phase felt smoother to the pair. The nine Merlin engines that power the Falcon 9 use super-cool liquid oxygen and rocket propellant to provide 1.7 million pounds of thrust at liftoff.

Behnken and Hurley will likely be joined later this year in the exclusive SpaceX flyers’ club. The first non-test mission, “Crew-1,” will send up astronauts Victor Glover, Michael Hopkins and Shannon Walker from NASA. They will be joined by Soichi Noguchi from Japan’s JAXA agency. The mission is expected to take place in the third quarter of 2020.

The Inverse analysis – The comments demonstrate how SpaceX’s entry into the rocket race is changing how astronauts experience spaceflight. Beyond the fuel switch, the Crew Dragon also uses a more futuristic-looking array of touchscreens on the inside, as opposed to the dials and levers better associated with traditional spacecraft.

As SpaceX gears up to fly the Starship, there could be more changes on the way. That ship, with the ability to send up to 100 people into space at a time, is set to be complete with an entertainment area and internal cabins. In the future, spaceflight may no longer be limited to the confines of a tiny capsule.

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.
