The next generation of London Tube trains

A new generation of London Underground trains enters service during 2024,* remaining in operation for 40 years.* The aging Tube network had been underinvested for decades – resulting in ever-worsening delays, overcrowding and safety issues. In the early 21st century, however, a massive programme of upgrades and modernisation was initiated. This included a £16bn ($26bn) project announced by Transport for London in October 2014, intended to fundamentally overhaul its rolling stock.

These futuristic new carriages were designed to accommodate the city's rapidly increasing population (forecast to grow by 37% to 11 million by 2050),* address safety concerns, improve usability for the disabled and offer a more pleasant overall experience for travellers. Step-free trains and wider doors would enable those in wheelchairs to have seamless access from platform to carriage, while door barriers placed on the edge (already introduced on the Jubilee Line) could prevent suicides or accidents.

With trains designed to be more spacious and easier to board – in combination with modern signalling and control systems – a faster, more frequent and more reliable service could be provided. The Piccadilly line, for example, serving many of London's top tourist attractions, would have its capacity boosted by 60%, equivalent to an extra 19,000 customers per hour.*

In the past, summer temperatures and humidity on some lines were known to reach levels unsuitable for cattle transport, let alone humans. All of these new carriages now feature air conditioning, for vastly improved comfort. In addition, hi-tech electronic displays provide real-time information, while better lighting creates more of a "living room" feel.

The New Tube is first introduced on the Piccadilly line in 2024, followed by the Bakerloo, Central and Waterloo & City lines. Self-driving trains are deployed from the early 2030s.* These had already been present on some parts of the network, such as the Docklands Light Railway (DLR) in the Canary Wharf financial district. As they become widespread on the main Tube lines as well, these automated systems bring to an end the notorious union strikes that had caused severe disruption in earlier decades.

Another development in 2024 is access to 4G, which is now available in all stations and tunnels. The final installations are completed this year, with plans now underway for upgrading the network to 5G.

Vladimir Putin steps down as President of Russia

On 18th March 2018, the incumbent Vladimir Putin won re-election as President of Russia with 76.7% of the vote. This was his second consecutive (fourth overall) term in office and expected to last for six years. According to Article 81 of the Constitution of the Russian Federation, a candidate for President was prohibited from serving more than two terms consecutively. In a broadcast on state TV, Putin had promised to abide by the rules and confirmed that he would step down from his position when legally required to do so, joking with reporters: "Am I supposed to be in this post until I'm 100 years old? No!"

Putin had experienced this restriction before – previously standing down in 2008 when Dmitry Medvedev took over, during which time Putin was appointed as the Prime Minister for a period of four years. His fourth term as President ends in May 2024. This makes him Moscow's longest-serving leader since the Soviet dictator Joseph Stalin.*

Open-source, 3D printed clothes at near-zero cost

3D printing – having emerged as a mainstream consumer technology – is now so cheap, fast and easy to use that it can produce items of clothing for just a few cents.* A milestone was passed in 2014 when 3D printing became faster than injection moulding.* The speed of printing continued to increase, doubling every two years in a trend similar to Moore's Law. By 2024, it is over 30 times faster, so an item which took four hours to print in 2014 now takes just seven and a half minutes.* Millions of open-source designs are available to download. Sweatshops in the developing world are declining as a result, with low-paid factory jobs made increasingly obsolete.

The Thirty Metre Telescope is fully operational

The Thirty Metre Telescope (TMT) is a huge new observatory built on the summit of Mauna Kea in Hawaii, USA.* It is funded through an international collaboration between governments and scientific institutions in Canada, China, India, Japan and the United States.

The TMT operates in the near-ultraviolet to mid-infrared (0.31 to 28 μm wavelengths) part of the spectrum* and is designed as a general-purpose observatory for investigating a broad range of astronomical phenomena. The centrepiece of the building is a Ritchey-Chrétien telescope with a 30-metre (98 feet) diameter primary mirror, which is segmented and consists of 492 smaller (1.4 m) hexagonal mirrors. The shape of each segment– as well as its position relative to neighbouring segments – can be controlled actively. The mirror is housed in a dome with a diameter of 66 metres (217 feet) and height of 55 metres (180 feet), comparable to an 18-storey building.

Among the existing and planned telescopes of 20 metres or larger, the TMT is located at the highest altitude, sitting 4,050 metres (13,290 feet) above sea level, which provides exceptional clarity of night sky objects. Even greater sharpness is achieved by its adaptive optics system, which helps correct image blur caused by the Earth's atmosphere.* Extremely high contrast exoplanet imaging is therefore possible. It can detect Earthlike planets around distant stars and take spectroscopy of those worlds to analyse the potential for life in greater detail than ever before.

The TMT's other capabilities include revealing the structure of hidden dark matter, which is believed to account for 27% of the total mass-energy content of the known universe. The nature of "first-light" objects can also be determined by peering far back into the young universe. The early formation and evolution of the large-scale structures that dominate the present day universe can also be observed. In addition, supermassive black holes can be analysed at very high resolution. This allows scientists to measure the general relativistic effects and to spatially resolve the accretion disks for active black holes in the centres of galaxies to the distance of the Virgo cluster, around 55 million light years away.*

The TMT mirror has a collecting area nine times greater than the neighbouring Keck Telescope, with a spatial resolution over 12 times sharper than the Hubble Space Telescope.*

Indonesia gets a new capital city

In 2024, a new capital city is established for Indonesia – its fourth in the last 80 years. Following World War II, Jakarta had become the de facto capital of the Republic of Indonesia. During occupation by the Netherlands Indies Civil Administration (NICA), the capital was moved to Yogyakarta in 1946 and then later Bukittinggi in 1948. It reverted back to Yogyakarta in 1949. Once independence was secured, Jakarta again became the capital in 1950, a position it would hold for the next 74 years.

In 2019, President Joko Widodo officially announced a relocation of Indonesia's capital to East Kalimantan on the island of Borneo. The as-yet-unnamed city – costing tens of billions of dollars to plan and build – was needed due to major subsidence in Jakarta. Due to the combined effects of its location on swampy land, and over-extraction of groundwater, Jakarta had been sinking at an incredible rate: up to 25cm (10in) each year in some of the worst affected parts, and almost half now sat below sea level. Jakarta also suffered from dire pollution, overcrowding and traffic problems.

The new capital, on a plot of 40,000 hectares (400 sq km), would be surrounded by greenery in a sparsely populated area, yet at the same time positioned in a more central and geographically unifying part of the country. One fifth of the approximately $34 billion needed would be financed by the state, with international investors contributing the remainder. The government pledged $40 billion to modernise and prevent the sinking of Jakarta, insisting that it was "not abandoning" the city. Without this action, 95% of Jakarta faced inundation by 2050.*

Indonesia's Ministry of Public Works and Public Housing organised a design contest, with Nagara Rimba Nusa ('Forest Archipelago') by URBAN+ announced as the winner in December 2019.* The masterplan featured strong environmental credentials and the latest in "smart city" technology. It would be developed in phases with construction starting in 2021, official inauguration taking place in 2024 and the last remaining government departments in Jakarta being transferred across by the end of the decade.

Total solar eclipse across North America

A total solar eclipse occurs on 8th April 2024, visible across North America.* For observers on the continent, totality begins at the Pacific coast, moving in a northeasterly direction through Mexico, the USA, and Canada, before ending in the Atlantic Ocean. Its longest duration is four minutes and 28 seconds near the small town of Nazas, Durango, Mexico,* and the nearby city of Torreón, Coahuila. This is the first total solar eclipse to be visible from Canada since 1979, the first in Mexico since 1991 and the first in the USA since 2017. It is the only total solar eclipse in the 21st century where totality is visible in all three countries.

The path of this eclipse crosses the path of the prior total solar eclipse of 21st August 2017, with the intersection of the two paths being in southern Illinois, in Makanda, just south of Carbondale. The cities of Benton, Carbondale, Chester, Harrisburg, Marion, and Metropolis in Illinois; Cape Girardeau, Farmington, and Perryville in Missouri, as well as Paducah, Kentucky, are within a 9,000 square mile intersection of the paths of totality of both the 2017 and 2024 eclipses – therefore earning the rare distinction of being witness to two total solar eclipses within a span of seven years.

Euro 2024 is hosted by Germany

Euro 2024 is the 17th edition of the European Championship, a quadrennial tournament organised by UEFA. It is hosted by Germany – the first time it has performed this role as a unified country (West Germany had hosted the games in 1988). 51 matches are played over a period of 32 days in June and July with 24 teams competing in the tournament.

During the bid process, only two countries had put themselves forward as candidates. Alongside Germany was Turkey. However, the latter's poor record in the area of human rights, its limited hotel capacity in many cities and the scale of infrastructure required were all of concern. Germany was announced as the winner by 12 votes to 4, with one abstention, on 27th September 2018.*

As hosts, the German team qualifies automatically. This provides a boost to German football after a disastrous 2018 World Cup, when the country failed to qualify for the last 16.

A plethora of stadia were available to satisfy UEFA's minimum capacity requirement of 40,000 seats. A total of 18 cities and stadia had submitted proposals, including the 12 hosts of the 2006 FIFA World Cup, but only ten cities and stadiums are used for the competition, the largest being the 75,000-capacity Olympiastadion in Berlin.

Paris hosts the Summer Olympic Games

From 2nd to 18th August 2024, the French capital hosts the 33rd Summer Olympics. Paris becomes the second city after London (1908, 1948 and 2012) to host the Olympic Games on three occasions. 2024 also marks the centennial of the 1924 Summer Olympics, which were held in the same city, and was the last time Paris held the Olympic Games.

Bidding to host the Games started in 2015 with five candidate cities, but Hamburg, Rome and Budapest withdrew, leaving Paris and Los Angeles as the only remaining candidates. A proposal to elect the 2024 and 2028 Olympic host cities at the same time was approved by an Extraordinary IOC Session in July 2017, in Switzerland. The IOC made a deal with Los Angeles to host the 2028 Games, which made Paris the host of the 2024 Games. The formal announcement of the hosts for both Olympiads took place at the 131st IOC Session in Lima, Peru, on 13th September 2017.*

Lunar Mission One drills into the Moon's south pole

Lunar Mission One is a British-led, unmanned Moon probe launched in 2024.* It attempts to land on the lunar south pole – a region largely unexplored until now – before drilling down at least 20m (65 ft) and trying to reach as deep as 100m (328 ft). This provides fresh new insights into the Moon's composition and geologic history, revealing new clues about the early Solar System. The mission gains crowdfunding through Kickstarter.* Backers are able to contribute photos, text and even their DNA in a time capsule, leaving a digital record of civilisation. Detailed analysis of the surface environment helps to gauge the suitability of the lunar south pole as a location for a permanent human base in future decades.*

Bio-electronics for treating arthritis are in common use

Arthritis is a form of joint disorder caused by trauma or infection of a joint, or old age. As of the 2010s, it was the single most common type of disability in the United States, predominantly affecting the elderly and resulting in over 20 million individuals having severe limitations in function on a daily basis. Total costs of arthritis cases were close to $100 billion annually, a figure expected to increase dramatically in the future with an aging population. Treatments for arthritis usually involved a combination of medication, exercise and lifestyle modification, but a cure remained elusive.

In 2014, a breakthrough involving the use of bio-electronics was unveiled by researchers. This took the form of a pacemaker-style device embedded in the necks of patients, firing bursts of electrical impulses to stimulate the vagus nerve – a crucial link between the brain and major organs. The impulses were shown to reduce activity in the spleen, in turn producing fewer chemicals and immune cells that would normally cause inflammation in the joints of patients with rheumatoid arthritis. Over half of people saw a dramatic improvement, even for severe symptoms, with up to 30% achieving remission.

After successful clinical trials, another decade of progress led to next-generation implants miniaturised to the size of rice grains, as well as improvements in cost and efficacy. By 2024, it is a routine form of treatment in many countries.* Bio-electronics are showing promise in other areas too. For example, they can prevent the airway spasms of asthma, control appetite in obesity, and help restore normal insulin production in diabetes.

Carsharing has exploded in popularity

Carsharing is a model of car rental where people rent cars for short periods of time, often by the hour. It is attractive to customers who make only occasional use of a vehicle, as well as others who need access to a vehicle of a different type than they use day-to-day. While some firms had experimented with the concept in the late 20th century, it only became well established in the early 21st. From the 2000s onwards, a growing trend of flexible, multi-modal, on-demand mobility led to rapid expansion of carsharing services. By 2015, carshare programs were available on five continents, over 30 countries and in hundreds of cities worldwide. Rising urbanisation, increasing problems of congestion and pollution, and the social and personal costs of private car ownership continued to drive demand for alternatives such as carsharing.

New innovations included one-way carsharing services for shorter, spur-of-the-moment trips; automakers partnering with garage chains to give users free parking in city centres;* ride-hailing mobile apps; the adoption of plug-in electric vehicles; and a small but growing number of self-driving vehicles. While the industry continued to expand in Europe and North America, most of the new growth was occurring in the Asia Pacific region, particularly China. In 2014, membership of carsharing programs stood at 2.4 million. By 2024, this has increased nearly ten-fold to reach 23.4 million while global revenue has risen six-fold, increasing from $1.1 billion to $6.5 billion.

Wind turbine drone inspection is a multi-billion dollar industry

As the world shifts towards clean energy, the number of wind turbines is growing exponentially. With so many installations, there is now enormous demand for inspection and maintenance of these structures. This is occurring alongside rapid uptake of drones and other unmanned aerial vehicles (UAV), which can provide a faster and cheaper alternative to traditional inspections. Until now, most of these jobs involved either simple ground-based visual assessments, or complicated and risky rope or platform access (sometimes at heights of 600 feet). By contrast, drones are essentially risk-free, extremely quick in their operations and offer much higher resolution than human eyes, while automating much of the image processing, data analysis and other tasks. By 2024, global revenue for wind turbine UAV sales and inspection services has reached almost $6 billion.**

Starlink reaches full capacity

Starlink is a new worldwide satellite broadband network created by SpaceX. It consists of more than 4,400 cross-linked satellites in the "smallsat" class (weighing just a hundred or so kilograms each), orbiting at an altitude of 1,100 km (680 mi). This is quadruple the number of active satellites that were operational a decade earlier, which is made possible because they are mass-produced at much lower cost per unit of capability than existing satellites.

The SpaceX CEO, Elon Musk, initiated the project after noting a significant unmet demand for low-cost global broadband capabilities. Smaller satellites were seen as crucial to lowering the cost of space-based Internet and communications. The Starlink network provides gigabit speeds at latencies of around 25ms; about as low as cable Internet service. Normally this would not be possible with satellites, but Starlink would use low-Earth orbits.

Flight testing began in 2017 with two prototype satellites – MicroSat-1a and MicroSat-1b. After communicating with ground stations, these experiments were followed by the network of 4,400 satellites, which began launching in 2019. This network reaches full capacity by 2024.*

Along with projects from rival companies such as OneWeb and Google, the Starlink network helps to further expand the reach of the Internet, as well as increasing the average user's connection speed. Some years later, an even larger network of 7,500 satellites at lower altitude is developed by SpaceX to boost capacity and reduce latency in densely populated areas. Further into the future, a similar network is placed in orbit around Mars.*

The first probe to fly into the Sun's outer atmosphere

Parker Solar Probe (formerly known as Solar Probe Plus) is a historic mission flying into the Sun's outer atmosphere (corona) for the first time. The probe travels to within 5.9 million km (3.6 million miles) of the Sun's surface – just four times the length of its diameter.

At such close range, an extremely strong shield is needed at the front of the spacecraft. This is made of reinforced carbon-carbon composite, able to withstand temperatures of 2000°C. At closest approach, the Parker Solar Probe hurtles around the Sun at approximately 450,000 miles per hour; fast enough to get from Philadelphia to Washington in one second.

The mission's primary scientific goals are:

• To determine the structure and dynamics of the magnetic fields at the sources of solar wind.
• To trace the flow of energy that heats the corona and accelerates the solar wind.
• To determine what mechanisms accelerate and transport energetic particles.
• To explore dusty plasma near the sun and its influence on solar wind and energetic particle formation.

Coming closer to the Sun than any previous craft, the Parker Solar Probe uses a combination of in situ measurements and 3D imaging to revolutionise our knowledge of the physics, origin and evolution of the solar wind. Its closest approach is in December 2024.*
