SpaceX won a NASA contract worth up to $843 million to build a single machine whose only job is to drag the space station out of orbit and into the Pacific Ocean

In 2019, Canada launched three radar satellites that can see through Arctic cloud and polar darkness, and now, with the original trio seven years into a seven-year design life, Ottawa has handed MDA Space a C$688 million contract to build the replacement before the constellation starts to fail

Astronomers at Cambridge have proposed that the galaxy may contain a vast and previously unrecognised population of habitable planets, characterised by a global liquid water ocean beneath a hydrogen atmosphere, that exist across a far wider range of stellar conditions than Earth-like worlds and that may be substantially easier to detect signs of life on than the Earth analogues that astronomers have been searching for over the past three decades

In June 2026, Amazon, Iridium, Globalstar and Telesat launched a trade group in Washington to represent the non-geostationary satellite industry, and the dominant operator they pointedly left out, SpaceX, already runs roughly 22 times as many satellites in that orbit as all four founding members combined

In April 2026, the Pentagon asked Congress to more than double the U.S. Space Force's budget, from roughly $31 billion to $71 billion, even as a new Mitchell Institute report warned that no one could yet agree where competition in orbit ends and open conflict begins

On June 19, 2026, MDA Space agreed to pay $620 million for Blue Canyon Technologies, a Colorado smallsat builder with 90-plus spacecraft launched, giving a Canadian company a U.S. defense foothold it could not build quickly from Ottawa

A commercial robot will try to catch NASA's sinking Swift telescope this month — a first for a satellite never built to be serviced

Artemis II astronaut Reid Wiseman on spacewalking: "I used to think I was scared of heights — now I know I was just scared of gravity"
Human Behaviour
We keep asking whether humans can survive on Mars and skipping the more important question of whether we should go at all

In July 1969, Buzz Aldrin pulled a packet of bread and a vial of wine from his personal preference kit aboard the lunar module Eagle and took Communion on the surface of the Moon while Houston went radio-silent, because NASA was already fighting an atheist's lawsuit over the Apollo 8 Genesis reading

In 1966, Soviet chief designer Sergei Korolev died on an operating table in Moscow at the age of 59, and two days later the newspaper Pravda printed his name and face for the first time — until that obituary, the man who launched Sputnik and put Gagarin in orbit was known publicly only as the Chief Designer

In May 1961, Alan Shepard became the first American in space, but only after a four-hour hold on the launch pad left him with a full bladder and no collection device, until he finally told the launch team he would have to go inside his sealed pressure suit, briefly short-circuiting his medical sensors

When John McFall lost his right leg at 19, no one could have known the former Paralympic sprinter might one day carry the first amputee body into orbit, where two weeks in microgravity could test what six decades of spaceflight medicine never measured
