The PLATO observatory is operational

PLAnetary Transits and Oscillations of stars (PLATO) was selected as the third medium-sized (M) mission in the European Space Agency's Cosmic Vision programme (the others being "Solar Orbiter" launched in 2017 and the Euclid Space Telescope launched in 2020). This observatory would include a payload of 34 separate telescopes and cameras, each comprised of four CCDs at 4500 x 4500 pixels resolution. It would scan up to a million stars, looking for truly Earth-like planets in sufficient detail to examine their atmospheres for signs of life.* In operation from 2024 until 2030,* at Earth-Sun Lagrangian point L2, the mission has the following objectives:

• Discover and characterise a large number of close-by exoplanetary systems, with a precision in the determination of the planet mass up to 10%, of planet radius of up to 2%, and of stellar age up to 10%.
• Detect Earth-sized planets in the habitable zone around solar-type stars
• Detect super-Earths in the habitable zone around solar-type stars
• Measure solar oscillations in the host stars of exoplanets
• Measure oscillations of classical pulsators

PLATO is aided by data from the Gaia mission launched in 2013, which provides many useful targets for subsequent follow-up observations.

BepiColombo arrives in orbit around Mercury

BepiColombo is a joint mission between the European and Japanese space agencies. It is only the third mission to study Mercury at close range and only the second to enter into orbit around the planet. Consisting of a rocket component and two science probes, the mission is launched in 2018. It performs a total of seven flybys around Earth, Venus and Mercury before orbital insertion on 1st January 2024. It is the most comprehensive on-location study of Mercury ever performed, with 12 specific objectives:

The European contribution, Mercury Planetary Orbiter (MPO), studies the surface and internal composition, while the Japanese probe, known as the Mercury Magnetosphere Orbiter (MMO), analyses the magnetosphere and atmosphere. A new form of ion engine is used for the propulsion system. BepiColombo was originally planned for a 2014 launch with 2020 arrival at Mercury, but faced a delay of four years. The mission concludes by 2026.*




The biggest refugee crisis in world history

Torrential flooding in southeast Asia – produced by a combination of rising sea levels, melting glaciers and extreme weather events – is creating the biggest refugee crisis in modern world history.* Bangladesh and neighbouring regions are seeing many millions of men, women and children displaced from their homes.

This unfolding horror is the worst environmental crisis of the 21st century so far. Although various different countries are affected, the disaster is centred on Bangladesh with its high density and population (150 million), situated in the low-lying Ganges River delta. With most of the country lying just a few metres above sea level, combined with a flat topography, storm surges are flooding huge areas of land. As well as the physical damage to infrastructure, salt in the ground means that fields up to 40 km from the new coastline are rendered useless for growing crops.

With so many refugees attempting to flee the region, conflicts begin to erupt along the borders with India and Burma. The sheer scale of this catastrophe makes it difficult to coordinate relief efforts, and relatively speaking, only token assistance can be offered by the UN.

African elephants are going extinct in the wild

Despite efforts to curtail the ivory trade, vast numbers of elephants continued to be poached throughout Africa. Their population – which stood at 600,000 in 2009 – declined by nearly 40,000 each year.* They are now on the verge of extinction, with few reported sightings in the wild. Zoos and parks are working to maintain a viable population for future rewilding.

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 side effect, 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.*

Completion of the Square Kilometre Array

Our view of the universe is greatly expanded with the completion of a major new observatory.* This radio telescope has a combined collecting area of approximately one kilometre. It operates over a wide range of frequencies and its size makes it 50 times more sensitive than any other radio instrument. By utilising advanced processing technology, it can survey the sky more than 10,000 times faster than ever before. With stations extending to a distance of 3,000 km from a concentrated central core, it continues radio astronomy's tradition of providing the highest resolution images in all of astronomy.

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.

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.*

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

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, a 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, Solar Probe Plus 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, Solar Probe Plus uses a combination of in situ measurements and 3D imaging to revolutionise our knowledge of the physics, origin and evolution of the solar wind.*

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.*
