SpaceX Inspiration4 mission: All-civilian crew touch down on Earth after historic three days in orbit

Published

on

Commander Jared Isaacman, pilot Sian Proctor, medical officer Hayley Arceneaux and mission specialist Chris Sembrosk took part in the Inspiration4 mission, making them the first to circle the world without a professional astronaut.

A SpaceX capsule carrying the first all-civilian crew into space has touched back down on Earth after three days in orbit.

The four amateur astronauts orbited the planet every 90 minutes at a speed of more than 17,000mph and an altitude of up to 363 miles – higher than the International Space Station and Hubble Telescope – during their time in space.

The Dragon capsule safely parachuted into the ocean just before sunset on Saturday, off the Florida coast where the private flight began three days ago. Upon re-entry through the Earth’s atmosphere, Dragon’s surface reached temperatures 3,500F (1,926C).

“Your mission has shown the world that space is for all of us,” SpaceX Mission Control radioed as the capsule landed.Advertisement

“It was a heck of a ride for us… just getting started,” replied trip sponsor Mr Isaacman, hinting at more private flights in the future.

Mr Isaacman, a billionaire, paid undisclosed millions for the trip for himself and his three guests – all of whom were strangers to him beforehand.

The group wanted to show that ordinary people could blast into orbit by themselves, and SpaceX founder Elon Musk took them on as the company’s first rocket-riding tourists.

Following the landing Mr Musk, who is worth an estimated $196.3bn, tweeted, “congratulations!”

Mr Isaacman, a 38-year-old entrepreneur and experienced pilot, aimed to raise $200m (£145m) for St Jude Children’s Research Hospital through the trip.

Donating $100m himself (£72.5m), he held a lottery for one of the four seats. He also held a competition for clients of his Allentown, Pennsylvania payment-processing business, Shift4 Payments, for another of the spots.

These were won by Mr Sembroski, 42, a data engineer in Everett, Washington, and Ms Proctor, 51, a community college educator, scientist and artist from Tempe, Arizona.

Ms Arceneaux, 29, a St Jude physician assistant who was treated at the Memphis, Tennessee hospital nearly two decades ago for bone cancer, took the last seat.

Together they spent six months training and preparing for potential emergencies during the flight but did not have to undergo the rigorous preparations that astronauts go through.

During the trip, the group was treated to unparalleled views of Earth through a large bubble-shaped window added to the top of the capsule.

They spent the time chatting with St Jude patients, conducted medical tests on themselves, rang the closing bell for the New York Stock Exchange, and complete some drawing and ukulele playing.

Ms Arceneaux, the youngest American in space and the first with a prosthesis, told her patients: “I was a little girl going through cancer treatment just like a lot of you, and if I can do this, you can do this.”

The four also took calls from Tom Cruise, interested in his own SpaceX flight to the space station for filming, and the rock band U2’s Bono.

They ate untypical space food: Cold pizza and sandwiches, pasta Bolognese and Mediterranean lamb.

Nearly 600 people have reached space – a scorecard that began 60 years ago and is expected to soon skyrocket as space tourism heats up.

The group is the first to end their flight in the Atlantic since Apollo 9 in 1969. SpaceX’s two previous crew splashdowns – carrying astronauts for NASA – were in the Gulf of Mexico.

NASA had little to do with the mission, only lending the use of its Kennedy Space Centre launchpad.

Meta: UK competition regulator tells Facebook owner to sell GIF library Giphy

Published

on

The investigation into the acquisition has been acrimonious, with Meta previously being fined £50m by the CMA for deliberately refusing to comply with the regulator’s inquiries.

Facebook’s owner Meta has been issued a legally binding order to sell the GIF library Giphy after an investigation found the takeover “could harm social media users and UK advertisers”.

The Competition and Markets Authority (CMA) launched an in-depth investigation into the deal in April after raising a number of concerns. It subsequently warned of the potential forced sale in August.

Giphy – a website for making and sharing animated images, known as GIFs – was acquired by Facebook (now Meta) in May last year to integrate the GIFs with Instagram, but the CMA has now ordered the acquisition to be unravelled.

Sky News understands Facebook intends to appeal the CMA’s decision. It has four weeks to do so and the appeal would go to a the Competition Appeal Tribunal, which is independent of the CMA.

Meta could potentially challenge that ruling in the UK courts, but only on points of law.Advertisement

Stuart McIntosh, who chaired the independent inquiry into the acquisition, said: “The tie-up between Facebook and Giphy has already removed a potential challenger in the display advertising market.

“Without action, it will also allow Facebook to increase its significant market power in social media even further, through controlling competitors’ access to Giphy GIFs.

“By requiring Facebook to sell Giphy, we are protecting millions of social media users and promoting competition and innovation in digital advertising,” Mr McIntosh explained.

The investigation into the acquisition has seen points of acrimony, with Meta being fined a record £50m by the CMA for deliberately refusing to comply with the regulator’s inquiries.

Meta argued that it has been in compliance with the competition watchdog’s primary orders at all times.

At the time of the fine, the company complained that the CMA delayed for seven months a request to amend these orders which was eventually agreed in what the company described as nearly an identical manner to what had been requested.

When Facebook first merged with Giphy it terminated the image library’s advertising services, “removing an important source of potential competition” according to the CMA.

This was considered “particularly concerning given that Facebook controls nearly half of the £7 billion display advertising market in the UK”.

However in Meta’s response to the preliminary findings, the social media giant described the acquisition as a simple vertical merger and said that Giphy was financially troubled and suggested that its attempts to monetise its GIF library for display advertising were unsuccessful.

“If GIF paid alignments were the promising business model that the CMA believes they are, then one would expect to encounter them in the real-world at scale… Yet that is not the case,” the response stated.

According to the regulator, the acquisition potentially also enabled the social media giant to change the terms of access to the GIF library for its competitors.

“For example, Facebook could require Giphy customers, such as TikTok, Twitter and Snapchat, to provide more user data in order to access Giphy GIFs.

“Such actions could increase Facebook’s market power, which is already significant,” the regulator said.

In its review of the merger, the CMA said it risked entrenching Meta’s market dominance, noting that its platforms (Facebook, Instagram, and WhatsApp) already accounted for 73% of all user time spent on social media in the UK.

A spokesperson for Meta said: “We disagree with this decision. We are reviewing the decision and considering all options, including appeal. Both consumers and Giphy are better off with the support of our infrastructure, talent, and resources.

“Together, Meta and Giphy would enhance Giphy’s product for the millions of people, businesses, developers and API partners in the UK and around the world who use Giphy every day, providing more choices for everyone.”

COVID-19: Mild and moderate cases during pregnancy doesn’t harm babies’ brains, finds study

Published

on

Parents should be reassured, there is “no evidence that a maternal SARS-CoV-2 infection has any effect on the brain development of the unborn child” say scientists.

Mild and moderate coronavirus infections in pregnant women appear to have no effect on the brain of the developing foetus according to a new study.

Two years into the COVID-19 pandemic “there is evidence that pregnant women are more vulnerable” to the coronavirus, according to a study presented to the Radiological Society of North America (RSNA).

The new study aims to identify what the possible consequences are for the unborn child if the mother is infected during pregnancy, and to study the likelihood of the virus being passed on to the foetus.

“Women infected with SARS-CoV-2 during pregnancy are concerned that the virus may affect the development of their unborn child, as is the case with some other viral infections,” said Dr Sophia Stoecklein, senior author of the study.Advertisement

“So far, although there are a few reports of vertical transmission to the foetus, the exact risk and impact remain largely unclear,” added Dr Stoecklein, from the department of radiology at Ludwig Maximilian University of Munich.

“The aim of our study was to fill this gap in knowledge regarding the impact of a maternal SARS-CoV-2 infection on foetal brain development,” she added.

MRI scans were used to study 33 pregnant women who were infected with COVID-19 during their pregnancy, with the women roughly 28 weeks into the pregnancies at the time of the scan.

The scans were evaluated by radiologists with years of experience in foetal MRIs who found that the brain development in the assessed areas was age-appropriate in all of the children, with no findings indicating any infection affected the brains.

“In our study, there was no evidence that a maternal SARS-CoV-2 infection has any effect on the brain development of the unborn child,” Dr Stoecklein said. “This fact should help to reassure affected parents.”

But she cautioned that only mothers with mild to moderate symptoms who were not hospitalised were included in the study, meaning the impact of “severe infection on brain development in the foetus has not been conclusively determined”.

Earth’s water may have come from the Sun, new research finds

Published

on

Researchers at the University of Glasgow say there is evidence that particles emitted by the Sun created water on the surface of dust grains on asteroids which hit Earth.

The origin of Earth’s water continues to be debated by scientists – whether it was here when the planet formed or if it had an extraterrestrial source.

But new research points the finger at a previously uncounted point of origin: the Sun at the centre of our solar system.

According to astronomers, solar radiation may have created water on the surface of dust grains carried on asteroids that smashed in to our planet billions of years ago.

Water covers more than 70% of our planet’s surface, but the exact source has puzzled scientists for decades if not longer.

A new study published in the journal Nature Astronomy suggests it has found a source which perfectly matches the isotopic signature of water on Earth.Advertisement

The research, led by scientists at the University of Glasgow, used a process called atom probe tomography to analyse different asteroid samples – some of which carry water and others which orbit too close to the Sun to do so.

Dr Luke Daly, from the University of Glasgow and the study’s lead author, said: “The solar winds are streams of mostly hydrogen and helium ions which flow constantly from the Sun out into space.

“When those hydrogen ions hit an airless surface like an asteroid or a space-borne dust particle, they penetrate a few tens of nanometres below the surface, where they can affect the chemical composition of the rock.

“Over time, the ‘space weathering’ effect of the hydrogen ions can eject enough oxygen atoms from materials in the rock to create H2O – water – trapped within minerals on the asteroid.

“Crucially, this solar wind-derived water produced by the early solar system is isotopically light.”

“That strongly suggests that fine-grained dust, buffeted by the solar wind and drawn into the forming Earth billions of years ago, could be the source of the missing reservoir of the planet’s water,” Dr Daly added.Thousands of people could still be killed by a completely unpredictable asteroid impact

Professor Bland at Curtin University explained that the existing theory that water was carried to Earth in the final stages of its formation by water-carrying asteroids didn’t hold up to examination.

“Previous testing of the isotopic ‘fingerprint’ of these asteroids found they, on average, didn’t match with the water found on Earth meaning there was at least one other unaccounted for source,” he said.

“Our research suggests the solar wind created water on the surface of tiny dust grains and this isotopically lighter water likely provided the remainder of the Earth’s water,” added the professor, who works at the Space Science and Technology Centre at Curtin University.

“This new solar wind theory is based on meticulous atom-by-atom analysis of miniscule fragments of an S-type near-Earth asteroid known as Itokawa, samples of which were collected by the Japanese space probe Hayabusa and returned to Earth in 2010.

“Our world-class atom probe tomography system here at Curtin University allowed us to take an incredibly detailed look inside the first 50 nanometres or so of the surface of Itokawa dust grains, which we found contained enough water that, if scaled up, would amount to about 20 litres for every cubic metre of rock,” added Professor Bland.
