LRO thermal data and UCLA-led modelling show why permanent shade in certain lunar pits can remain near 17°C, while cave habitability still depends on access, structure, air and power.
Venera 13 turned a planned 32-minute Venus surface mission into 127 minutes of confirmed transmission, completing colour panoramas, drilling and X-ray soil analysis.
Alan Shepard's 15-minute Mercury flight in May 1961 was delayed so long on the pad that he had to urinate inside a suit engineers had never designed for it — and the fix set the template for every plumbing system flown since.
NASA's monthly bone-loss range shows the scale of the Mars-transit risk, but individual outcomes depend on duration, exercise, nutrition and whether loss continues linearly beyond six months.
Starship has unmatched liftoff thrust, but its Mars architecture still depends on an unproven vehicle-to-vehicle cryogenic refuelling system.
NASA's palm-sized HPSC processor is indicating a 500-fold performance gain in JPL tests, with qualification still ahead.
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.
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.
Luna 3 revealed the Moon's sunlit far side in October 1959, less than 56 years after the Wright brothers' first powered flight.
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.
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.
A billion-kilometre journey ended not with a bang but with a bounce—revealing unexpected truths about one of Saturn's most alien moons.
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.
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.
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.
A space company bet billions on a technology it hadn't built, then weaponized a patent against a rival already proving it worked.
