Richard Branson set to leave Earth: What you need to know about the billionaire space race

The last century’s space race was a competition between the world’s great powers and a test of their ideologies. It would prove to be a synecdoche of the entire Cold War between the capitalist United States and the socialist Soviet Union.

The starting pistol in the race to the future was fired in 1961 when President John F Kennedy committed to “achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth” and it ended with a US victory on 24 July 1969 when the crew of the Apollo 11 mission splashed down safely in the Pacific Ocean.

There are no such stakes in today’s race. The values of the future aren’t in question, merely the egos of three billionaires. One of these men is launching his private spacecraft off the planet on Sunday. Another follows suit soon after.

So here’s how they compare and what you need to know:

“My mum taught me to never give up and to reach for the stars,” said Sir Richard Branson announcing that he was going to be among the first people his spaceflight company launches on a mission.

Unfortunately, not only will Virgin Galactic’s mission fall short of the stars, the two-and-a-half hour mission will also fall short of space, at least according to the internationally agreed definition.

VSS Unity is a spaceplane (perhaps just a plane?) that launches in mid-air from the belly of a carrier aircraft at an altitude of about 15km, and then flies up to an altitude of about 80km, allowing the passengers to feel nearly weightless for approximately six minutes and glimpse the curvature of the Earth.

The problem for Sir Richard is that the Federation Aeronautique Internationale (FAI) defines the boundary between Earth’s atmosphere and outer space as 100km above Earth’s mean sea level, the so-called Karman Line, 20km higher than he is going to travel.

The definition of the edge of space is a bit of a challenge. Earth’s atmosphere doesn’t suddenly end but becomes progressively thinner at greater altitudes. In very simple terms, physicist Theodore von Karman’s solution was to define the edge of space as the highest point at which an aircraft could fly without reaching orbital velocity.

While Karman himself and the FAI regards this altitude as 100km, Sir Richard has the US Air Force and NASA on his side. They both place the boundary of space at 80km above mean sea level, partially because putting it at 100km would complicate issues regarding surveillance aircraft and reconnaissance satellites for the US – although the Department of Defence subscribes to the FAI definition.

It’s not clear whether this definition is covered by the small print of Virgin Galactic’s customer tickets, but ultimately the company aims to be operating multiple space tourism flights a year, and already has more than 600 customers for the $250,000 (£189,000) seats – including Justin Bieber and Leonardo DiCaprio.

“Ever since I was five years old, I’ve dreamed of traveling to space. On 20 July, I will take that journey with my brother,” said Jeff Bezos, announcing his seat on a journey to the edge of space.

Blue Origin’s New Shepard rocket is capable of actually making it there, with a maximum achieved altitude of above 100km, but how high it will bring its four passengers hasn’t yet been confirmed.

These passengers will be Jeff Bezos, his brother Mark, a mystery customer who paid $28m (£20m) for the seat in an auction, and 82-year-old Mary Wallace “Wally” Funk, a woman who had astronaut training in the 1960s but was denied the chance to go into space because of her gender.

While the mission will be scooped to launch by Virgin Galactic, by inviting Wally Funk it has managed to scoop Branson on getting a famous victim of gender injustice into space – she had previously put money down to fly with Virgin Galactic.

It will take three minutes to take the passengers up to the required altitude, at which point they will have three minutes more in which to enjoy their sudden near-weightlessness. They’ll be allowed to unbuckle their seatbelts and float around, as well as examine the curvature of the Earth through one of the capsule’s windows. Just over 10 minutes after launch, the spacecraft will land back on Earth.

The 20 July flight will fittingly occur on the anniversary of the moon landings in 1969, but unlike the Apollo missions there will be no human piloting the modules. Instead, Blue Origin’s New Shepard spacecraft is completely autonomous and will follow a programmed mission timeline before parachuting back to Earth.

The company has said that it expects to sell seats for more tourism flights in the future, but it isn’t clear how this will happen and the tickets for New Shepard are yet to go on general sale.

“I want to die on Mars – just not on impact,” Elon Musk once quipped, although he hasn’t announced his immediate intention to travel into space at all.

Unlike both Bezos and Branson, Musk’s private spaceflight company, SpaceX, has a long and successful history of launching payloads way beyond the 100km mark.

SpaceX has announced it will be launching an all-civilian mission into orbit by the end of the year, with the passengers actually orbiting around the planet for up to four days before returning to Earth.

All four crew seats on the mission have been paid for by Jared Isaacman, the founder of Shift4 Payments, who has declined to reveal the costs.

Isaacman is donating two of the seats to St Jude Children’s Research Hospital in Memphis, with one being given to a staff member there, and another intended to be raffled off to a member of the public. He hopes to raise $200m (£145m) for the hospital, alongside a $100m (£72m) donation of his own.

Elon Musk hasn’t mentioned flying on this mission himself, although he has long articulated a plan to travel to Mars, plans that have been described as a dangerous delusion by Britain’s chief astrophysicist Lord Martin Rees.

Back in 2016, Musk outlined his vision of building a colony on Mars “in our lifetimes” – with the first rocket propelling humans to the Red Planet by 2025.

For many years the company used an image of the Martian surface being terraformed (turned Earth-like) in its promotional material. However, a NASA-sponsored study published in 2018 dismissed these plans as impossible with today’s technology.

Recently Musk has tweeted he believed it was “possible to make a self-sustaining city on Mars by 2050, if we start in five years” but as of yet, SpaceX has not planned any missions to the planet.

Health warning issued as heatwave grips South and Southeast Asia

Countries in South and Southeast Asia have been coping with a weeks-long heatwave which has seen record temperatures sweep parts of the region.

Pupils in the Philippines, India and Bangladesh have been told to stay at home and learn remotely due to a severe health risk.

Schools in Cambodia have also cut back on their hours.

Cambodia faces its hottest temperature in 170 years, according to meteorologists – as high as 43C (109F).

Bangkok in Thailand has reached 40C (104 F), but the heat index is said to have topped 50 C (122 F) due to the heat being trapped among the mass of buildings.

The United Nations Children’s Fund warned in April that the heat could put the lives of millions of children at risk and asked people who care for them to take extra precautions.

A spokesperson for UNICEF said around 243 million children were exposed to hotter and longer heatwaves.

They said the increased heat was “putting them at risk of a multitude of heat-related illnesses, and even death”.

Thirty people in Thailand have died from heatstroke in the past month, according to data from the country’s health ministry.

People are being advised to avoid outdoor activities and to stay hydrated.

Several towns in Myanmar were included on lists of the hottest spots globally last month, with temperatures reaching 48.2C (118F) in at least one case.

Parts of eastern India also experienced their hottest April on record.

Kerala, on India’s west coast, this week instructed all schools and colleges to close until Monday, while influencers in Bangladesh have encouraging people to plant trees in response to the record heat.

Benjamin Horton, director of the Earth Observatory of Singapore, said there were three factors for heatwaves: a naturally-occurring climate phenomenon known as El Nino, an increase in global temperatures, and human-induced climate change.

Brazil is currently experiencing another climate phenomenon – La Nina – with 39 dead and 68 missing in floods across the country.

More than 24,000 people have been forced to leave their homes due to the flooding.

Scientists believe the naturally-occurring phenomenon has intensified due to the impact of climate change.

Philippine coastguard hits out at China’s ‘brute force’ after water cannon attack

Philippine coastguard hits out at China's 'brute force' after water cannon attack

China has been branded “a bully” and an international lawbreaker after its ships blasted Philippine vessels with water cannon in the South China Sea.

Sky News was on board the BRP Bagacay when a Chinese vessel fired water at it, causing significant damage.

Philippine coastguard spokesman Jay Tarriela told Sky News that this week’s confrontation was the first time China had used “such aggression” against their ships.

“The metal parts and the railing were bent. The canopy was also destroyed. So this came as a surprise for us that China never hesitated to use brute force,” he said.

“It completely justifies us calling The People’s Republic of China a bully country.”

The Philippine coastguard was on a resupply mission to the Scarborough Shoal to deliver food and fuel to Philippine fishermen when they were struck.

The submerged reef lies in disputed waters. China claims sovereignty over the reef but it is much closer to the Philippines and lies within its legally recognised exclusive economic zone.

The vessel Sky News was on board was the closest the coastguard had ever been to the shoal – just 600 metres away from it.

Asked if the mission to the shoal was a provocative move by the Philippine coastguard, Commodore Tarriela denied they were “poking the bear” but rather “driving the bear out of our own territory”.

The Philippines has been stepping up its patrols in the area under the instruction of President Bongbong Marcos, and reasserting its claim to the shoal in recent months.

It has raised the spectre of open conflict. While neither side currently wants that, there is now a greater threat of open conflict.

Asked what the end game was for the Philippines, Commodore Tarriela said their priority was to “tell the world” about China’s aggression.

He said their secondary goal was to ensure “like-minded states” also made China “fall in line and respect international law”.

“Otherwise, it’s everybody’s loss,” he added.

Philippine government policy is not to resist using water cannon against Chinese vessels – and Commodore Tarriela insisted that policy remains in place after the confrontation.

The government also remains intensely determined to protect the waters it believes it has every right to operate in.

“We’re not going to yield and we’re not going to surrender a square inch of our territory,” Commodore Tarriela insisted.

Beijing has called the action its own coastguard took as “necessary”.

Speaking at the Chinese foreign ministry’s daily news conference, spokesperson Lin Jian described the coastguard’s conduct as “professional, proper, and lawful”.

Three charged over killing of Sikh separatist leader in Canada – in incident which sparked diplomatic spat with India

Three charged over killing of Sikh separatist leader in Canada - in incident which sparked diplomatic spat with India

Three suspects have been charged by Canadian police over the killing of a Sikh separatist leader in Vancouver last June, in an incident that sparked a diplomatic spat between Ottawa and New Delhi.

Hardeep Singh Nijjar, 45, was shot dead outside a temple by masked gunmen in Surrey, outside Vancouver, on 18 June 2023.

Royal Canadian Mounted Police assistant commissioner David Teboul said police could not comment on the nature of the evidence or the motive.

“This matter is very much under active investigation,” Teboul said.

The three suspects – Indian nationals Kamalpreet Singh, Karan Brar and Karampreet Singh – were arrested in Edmonton, Alberta, the Royal Canadian Mounted Police said.

Superintendent Mandeep Mooker said: “This investigation does not end here. We are aware that others may have played a role in this homicide and we remain dedicated to finding and arresting each one of these individuals.”

Canadian Prime Minister Justin Trudeau sparked a diplomatic feud with India when he said in September that there were “credible allegations” of Indian involvement in the killing. India angrily denied involvement.

Mr Nijjar, an Indian-born citizen of Canada, was a leader in what remains of the Khalistan movement – a once-strong group calling for the creation of an independent Sikh homeland.

He was organising an unofficial referendum in India for an independent Sikh nation at the time of this death and had denied allegations of ties to terrorism.

The Khalistan movement has lost much of its power but is still supported by some in the Punjab state in northwestern India and in the Sikh diaspora overseas.

A violent, decade-long Sikh insurgency shook north India in the 1970s and 1980s, and was ultimately crushed in a government crackdown which saw thousands of people killed, including prominent Sikh leaders.

In June 1984, Indian forces stormed the Golden Temple, the holiest Sikh shrine in Amritsar, where separatists had taken refuge.

In more recent years, the Indian government has repeatedly warned that Sikh separatists were trying to make a comeback.

The diplomatic row saw diplomats expelled by both India and Canada.

The Indian government said it “completely rejected” Mr Trudeau’s allegations and added: “We are a democratic polity with a strong commitment to rule of law.”

The dispute derailed trade talks between the two countries and ultimately saw Canada withdraw 41 of its 62 diplomats in India.

At the time, Canada did not provide public evidence to back up Mr Trudeau’s allegations. However, it did reveal the claims were based on intelligence provided by a major ally and surveillance of Indian diplomats in the country.
