Mission Notes

Spaceflight and industry

Mission Notes follows the business and engineering of spaceflight. Rockets, satellites, contracts, and the industry behind the missions. Space Daily has reported on this beat since 1995, when the launch industry was a fraction of its current size.

Moon Daily

The Moon’s south pole can spend days in darkness, temperatures can plunge below −200°C, and unprotected electronics may not survive — Northrop Grumman is repurposing hardware built for NASA’s shelved Gateway station to test how lunar systems cope before astronauts are targeted to land in 2028.

Gateway-era hardware may help test lunar-surface thermal and electronics risks, but NASA has not finalised HALO's reuse and its early-2028 Artemis IV landing remains a target.

The first animals to circle the Moon weren’t astronauts—they were two Central Asian steppe tortoises aboard the Soviet Zond 5, which beat Apollo 8 by three months in 1968. They returned alive after the week-long journey, having lost only about 10% of their body weight.

Zond 5 sent two steppe tortoises around the Moon before Apollo 8, but the passenger list and 10 per cent weight-loss figure need context.

The far side of the Moon isn’t dark—it receives just as much sunlight over time as the side facing Earth. Yet humanity had never seen it until the Soviet Luna 3 probe photographed it in October 1959, less than 56 years after the Wright brothers’ first powered flight.

Luna 3 revealed the Moon's sunlit far side in October 1959, less than 56 years after the Wright brothers' first powered flight.

When Luna 2 struck the Moon in September 1959, its instruments had found no detectable lunar magnetic field or radiation belts, while two explosive spheres were meant to scatter 144 steel Soviet pennants across the impact site

On 13 September 1959, a 390-kilogram Soviet probe hit Mare Imbrium at roughly 3.3 kilometres per second, becoming the first human-made object to reach another world — and scattering, in theory, dozens of stainless-steel Soviet pennants across the impact site.

Saturn Daily

NASA is currently assembling a nuclear-powered octocopter in a Maryland cleanroom that is scheduled to reach Saturn’s moon Titan in 2034. Titan’s atmosphere is more than four times as dense as Earth’s while its gravity is only about one-seventh as strong—conditions that make rotorcraft flight extraordinarily efficient, with ideal hover calculations requiring roughly 40 times less power than on Earth.

Dragonfly's flight fuselage is in integration at Johns Hopkins APL. Titan's dense air and low gravity explain the ideal 40-to-one hover-power comparison, but not the spacecraft's full energy budget.

Huygens touched down on Titan at roughly the speed of a ball dropped from a metre up, denting the ground by 12 centimetres before it bounced, slid 30 centimetres, and wobbled five times on ground one scientist likened to snow frozen on top

A billion-kilometre journey ended not with a bang but with a bounce—revealing unexpected truths about one of Saturn's most alien moons.

Science

There is a spot in the South Pacific Ocean, 2,688 kilometres from the nearest land in every direction, where more than 263 decommissioned spacecraft lie on the ocean floor — and the closest humans to it are usually astronauts passing 400 kilometres overhead

Point Nemo is 2,688 kilometres from land, but its spacecraft cemetery is a broad re-entry region containing scattered fragments rather than intact wrecks.

In January 1961, a chimpanzee named Ham was strapped into a Mercury capsule and launched on a suborbital arc that overshot its target by roughly 240 kilometres, and when the hatch was opened aboard the USS Donner, he was found alive, slightly dehydrated, somewhat exhausted, and carrying a small abrasion across his nose

On 31 January 1961, a six-year-old chimpanzee named Ham rode a Mercury-Redstone rocket on the suborbital arc that would carry Alan Shepard three months later — and came back alive, uninjured, and unwilling ever again to sit in the couch.

In September 1983, a Soyuz rocket caught fire on the pad with two cosmonauts strapped in above it, and the flames burned through the cables carrying the abort command. Saving them came down to two controllers pressing their buttons within five seconds of each other

A catastrophic launch pad fire severed the only abort command to two trapped cosmonauts—until a forgotten backup system became their sole chance at survival.

In 2014, Blue Origin patented the idea of landing a rocket vertically at sea, before it had launched a single orbital rocket, then used the patent to try to block SpaceX from doing exactly what SpaceX was already attempting to do

A space company bet billions on a technology it hadn't built, then weaponized a patent against a rival already proving it worked.

Outer Planets

In 1989, Voyager 2 measured winds up to 2,100 kilometres an hour circling an Earth-sized storm on Neptune; by 1994, when Hubble looked again, the storm had simply vanished, unlike Jupiter’s Great Red Spot, which has raged for more than a century

Neptune's massive storms vanish in years, while Jupiter's have endured for centuries—a cosmic mystery about what makes some planetary tempests immortal and others ephemeral.

In the weeks before Apollo 11 launched, Neil Armstrong, Buzz Aldrin and Michael Collins spent their quarantine signing hundreds of autographs, not for fans, but so their families could sell them if the mission killed them, since no insurer would cover astronauts at all

The astronauts knew the odds. So they signed their names hundreds of times, turning autographs into an insurance policy their families might actually need.

In September 1983, a Soviet lieutenant colonel named Stanislav Petrov sat in a bunker south of Moscow watching his early-warning screens light up with five incoming American missiles, and instead of phoning it up the chain he decided the computer was lying and waited — a judgment call that historians now credit with preventing a retaliatory nuclear launch

Just after midnight on 26 September 1983, the Soviet Union's new Oko early-warning satellites told Lieutenant Colonel Stanislav Petrov that five American missiles were inbound. He decided the computer was lying — and was right.

Space Scopes

In 1966, the Soviet chief designer behind Sputnik, Gagarin’s flight, and the entire early space program died during routine surgery, and only then did the world learn his name was Sergei Korolev — for a decade Moscow had referred to him in print only as the Chief Designer, because the KGB feared the CIA would have him killed

For roughly a decade before his death in January 1966, Sergei Korolev — the engineer who built Sputnik, launched Gagarin, and ran the Soviet lunar program — was referred to in Soviet media only as the Chief Designer. His name appeared in print for the first time in his own obituary.

The Huygens probe detached from Cassini in December 2004 and spent 22 days coasting silently toward Titan before parachuting through an orange methane haze for two and a half hours, and when it thumped down on a plain of ice pebbles it kept transmitting for 90 more minutes from a moon nobody had ever seen the surface of

On 14 January 2005, ESA's Huygens probe parachuted through Titan's orange methane haze and kept transmitting for 90 minutes from the surface — still the most distant landing in history.

The stripes on Perseverance’s parachute were mostly there so engineers could see how the canopy was oriented, but the pattern also hid a message in binary, and the internet decoded it within hours of the landing — a motto, and a set of coordinates pointing at a spot on Earth

NASA engineers hid a secret message in the Perseverance rover's parachute stripes—one that amateur codebreakers cracked before the dust had settled on Mars.
