The future of travel beyond Earth.

Venus’s 467°C surface can melt lead and has destroyed landers within minutes or hours, yet at roughly 50 kilometres altitude its thick atmosphere provides radiation shielding comparable to Earth’s. Curiosity measured about 0.67 millisieverts per day on the Martian surface, making a floating Venus habitat substantially safer from radiation—though certainly not from sulphuric acid, carbon dioxide or the challenges of remaining airborne.

At 50 kilometres above Venus, a thick atmospheric column may provide Earth-like cosmic-ray shielding, but that advantage is modelled and applies to radiation rather than overall safety.

Deep Impact

A 710-metre asteroid in the main belt was found completing one rotation every 1.88 minutes—about 70 times faster than the limit beyond which a loosely bound rubble pile should begin breaking apart. Modelling suggests 2025 MN45 requires cohesion comparable to solid rock, perhaps because it is a compact fragment left by the destruction of a larger parent body.

Rubin Observatory measured a 710-metre main-belt asteroid turning once every 1.88 minutes, requiring rock-like cohesion under the study's model.

The flag Apollo 11 planted on the Moon cost just $5.50, and when the Lunar Reconnaissance Orbiter examined the six landing sites in 2012, shadows indicated that five flag assemblies were still standing. Apollo 11’s had apparently been flattened by the lunar module’s ascent exhaust, while decades of unfiltered ultraviolet radiation may have bleached the surviving nylon flags white.

The inexpensive nylon flag needed a purpose-built lunar assembly, and orbital shadows reveal more about the surviving poles than they do about the condition or colour of the cloth.

When Luna 9 made the first successful soft landing on the Moon on 3 February 1966, astronomers at Jodrell Bank recognised that its unencrypted picture signal resembled the Radiofax format used by newspapers. The Daily Express supplied a facsimile receiver, allowing the first photographs from the lunar surface to appear in Britain before Moscow officially released them.

Jodrell Bank turned Luna 9’s open picture signal into a printable image with a newspaper facsimile receiver before the Soviet official release.

About Space Travel

The future of travel beyond Earth.

Space Travel is an independent publication covering human spaceflight, commercial missions, rocket technology, launch operations, and the engineering driving the future of exploration. The site pairs a deep archive with current reporting on the agencies, companies, research programs, and technical breakthroughs shaping how people and payloads move beyond Earth. We employ modern AI technologies to support our editorial workflows; every published piece is editorially directed and reviewed.
