Christine Darden, a NASA engineer, wrote computer programs to predict sonic booms, the thunder-like bangs made by aircraft flying faster than sound. Her research showed that reshaping a plane's nose and wings could make them softer on the ground.

The story behind the card

Darden, a mathematics graduate of Hampton Institute, joined NASA's Langley Research Center in 1967 as a 'human computer', doing calculations for engineers. She pressed her managers to move her into engineering, and in the 1970s they did. A sonic boom forms when the shock waves from an aircraft's nose, wings and tail merge into one sharp jolt that reaches the ground. Darden's programs modelled those waves and pointed to shapes that keep them from merging, so people below hear a softer thump. She earned a doctorate in engineering from George Washington University in 1983, led NASA's sonic boom team from 1989 and wrote more than 50 papers. NASA's X-59, which first flew on 28 October 2025, was built to test this idea. Her story is also told in Margot Lee Shetterly's book Hidden Figures.

NASA mühendisi Christine Darden, ses hızını aşan uçakların yarattığı gök gürültüsüne benzer patlamaları, yani sonik patlamaları önceden hesaplayan bilgisayar programları yazdı. Araştırmaları, uçağın burnu ve kanatları yeniden biçimlendirilirse bu patlamaların yerde daha yumuşak duyulabileceğini gösterdi.

Hampton Institute'ta matematik okuyan Darden, 1967'de NASA'nın Langley Araştırma Merkezi'ne mühendisler için hesap yapan bir “insan bilgisayar” olarak girdi. Mühendisliğe geçmek için yöneticilerini zorladı ve 1970'lerde bunu başardı. Sonik patlama, uçağın burnundan, kanatlarından ve kuyruğundan çıkan şok dalgalarının birleşip yere tek ve sert bir darbe olarak ulaşmasıyla oluşur. Darden'ın programları bu dalgaları modelledi ve dalgaların birleşmesini önleyen biçimleri gösterdi; böylece yerdekiler daha hafif bir gümbürtü duyar. 1983'te George Washington Üniversitesi'nde mühendislik doktorası aldı, 1989'dan itibaren NASA'nın sonik patlama ekibini yönetti ve 50'den fazla makale yazdı. İlk uçuşunu 28 Ekim 2025'te yapan NASA'nın X-59 uçağı tam da bu fikri sınamak için yapıldı. Hikâyesi Margot Lee Shetterly'nin Gizli Sayılar (Hidden Figures) kitabında da anlatılır.

Radia Perlman, an American engineer, invented the spanning-tree algorithm, which stops data from circling endlessly in computer networks that have duplicate connections. It keeps the spare links switched off and brings one back into use when a cable fails.

When a network has more than one path between two points, a message can loop round and round, copying itself until the network jams. Perlman solved this in the mid-1980s while working at Digital Equipment Corporation. Her method lets the switches that connect a network agree among themselves, with no central controller, on one loop-free set of routes shaped like a branching tree; the extra links wait on standby. If a link breaks, the switches recalculate and a standby link takes over. The IEEE, the body behind many networking standards, adopted the method as 802.1D in 1990, and it and its faster successors still keep office and campus networks running. Perlman even described the algorithm in a short poem, “Algorhyme”.

A solar sail is a huge, ultra-thin mirror that lets a spacecraft travel on the faint push of sunlight. It needs no fuel, and the tiny push keeps adding speed for as long as light falls on it.

Light has no mass, but it carries momentum, so when it bounces off a mirror it gives it a tiny push. The idea goes back to Johannes Kepler, who noticed in the early 1600s that comet tails point away from the Sun and imagined ships sailing on a heavenly breeze. In 2010 Japan's IKAROS became the first spacecraft to use a solar sail in interplanetary space, on its way past Venus. In 2019 the Planetary Society's LightSail 2, partly funded by public donations, showed that a small satellite could raise its orbit using sunlight alone; it burned up in the atmosphere in 2022. The push is tiny, but it never runs out, so over months it adds up.

On 26 September 2022, NASA's DART spacecraft deliberately crashed into Dimorphos, a small asteroid orbiting a larger one, and cut the time it takes to circle its partner by about 33 minutes. It was the first proof that an impact can change an asteroid's path.

DART, short for Double Asteroid Redirection Test, launched in November 2021 and hit Dimorphos, about 150 metres across, at roughly 6.1 kilometres per second. Neither Dimorphos nor its partner Didymos was ever a threat to Earth; the pair was chosen because a change in the small asteroid's orbit is easy to measure with telescopes. Before the impact, Dimorphos circled Didymos every 11 hours and 55 minutes. The team would have counted a change of 73 seconds as success; the actual change was about 33 minutes, partly because the impact threw off a huge plume of rock and dust that pushed the asteroid further. A small Italian satellite, LICIACube, photographed the plume, and the European Space Agency's Hera probe, launched in 2024, is due to arrive in late 2026 to study the crater.

NASA's Parker Solar Probe, launched in 2018, flies through the Sun's outer atmosphere, the corona. In December 2024 it passed just 6.1 million kilometres from the solar surface, closer than any spacecraft before it.

The probe is named after the astrophysicist Eugene Parker, who in 1958 predicted the solar wind, the stream of charged particles flowing out from the Sun; it was the first NASA spacecraft named after a living person. A carbon-composite heat shield about 11 centimetres thick faces the Sun and heats to around 1,000 °C, while the instruments behind it stay near room temperature. Seven flybys of Venus shrank its orbit step by step. At its closest passes it travels at about 690,000 kilometres per hour, the fastest any human-made object has gone. In 2021 it became the first spacecraft to fly through the corona. Its measurements help explain how the solar wind is launched and how solar storms can disrupt satellites and power grids.

Fazlur Rahman Khan, a Bangladeshi-American structural engineer, made very tall buildings cheaper to build with his 'tube' systems, in which a tower's outer walls work together to resist the wind. They shaped Chicago's John Hancock Center and the Sears Tower, now Willis Tower.

Before Khan, most skyscrapers relied on a rigid internal frame of steel columns and beams, and the taller they went, the more steel they needed to keep them from swaying in the wind. In Khan's framed tube, columns are set close together around the outside of the building and tied by deep beams called spandrels, so the whole outer wall acts like one stiff, hollow tube anchored in the ground. Working at the Chicago firm Skidmore, Owings & Merrill, he developed variations: the John Hancock Center (1969) braces its tube with giant diagonal X-shapes, and the Sears Tower (1973) bundles nine tubes together. Khan was born in Dhaka in 1929 and died in 1982.
