Every notable build since the in-game What's New panel came online in July, across Explore and Play.

October 4
2026-10-04- featureBuild hexes for colony buildings. Several colony buildings now pack edge to edge on a 9 m build-hex lattice inside one claimed cell, each claiming only its hull and berm, and finished neighbours shorten a new building's on-site time.
- artColony night lights. At night each colony building carries its own lamp rig, with door lights, connector strips, red obstruction lights and the magenta grow light through the glazing, instead of standing in a fully lit hex.
- fixDelta-V Map trips on Explore. The Delta-V Map on Explore lists the same trips Play does from the same start, and GO on a row flies it.
- fixEarth date on the clock. The clock panel at the top of Play and Explore now opens with the Earth date and UTC time, with the Mars sol and year beneath it.
- fixEvery building on a plot is drawn. A plot no longer stops at eight structures: every building past the eighth is now drawn, graded and lit.
- fixFly down onto the summit. Picking Everest, Denali or Aconcagua from the Atlas region list turns the view onto the summit and flies straight down to it, without the mountain building itself on screen.
- fixLagrange labels give way in flight. In flight, a Lagrange marker's label fades while it overlaps the target's name, distance or pin, and comes back when they separate.
- artMagenta Grow Lights and a New Landing Pad. A new landing pad rises on its own surveyed hex plot at Jezero Delta, Mars. Greenhouse domes glow magenta at night as the shot moves from day into night. Scored with Erik's own Suno track, "Serene Ascent."
- featureSatellites hold their slots past the snapshot. Starlink, Kuiper and Iridium NEXT keep their slots past the snapshot, the ISS follows NASA's predicted track, and a satellite 30 days past its elements is hidden.
- artThe real night sky. Stars drift with their measured proper motion on the game clock, the Milky Way comes from the NASA Deep Star Maps, and ship hulls reflect the real sky instead of a painted one.

- featureLeap seconds. The sim clock renders all 27 historical leap seconds, including 2016-12-31 23:59:60Z.
- featureWeekly satellite ingest. A weekly job pulls the latest complete week of Earth-satellite orbital data, with an alarm if it ever fails.
- artColony on Jezero Delta. Landing pad, greenhouse dome and survey stakes placed across the Martian plot.
October 3
2026-10-03- featureSatellites, phase 1. A full October 3 snapshot of real satellite positions and orbits, color-coded by type.
- featureReal-Earth terrain. Mount Everest and the Alps, from orbital survey altitude down to a ground-level walkaround.
- featureTransfer windows. Autopilot offers the next, next-next and best-of-the-next-five windows for any body-to-body flight plan.
October 2
2026-10-02- featureLagrange points & barycenters. Sol-Earth, Sol-Mars, Sol-Jupiter and Earth-Luna Lagrange points, plus the Sol-Jupiter and solar-system barycenters.
- artMartian sunsets. Accurate sun scattering and atmospheric sunsets over Jezero Delta.
- fixSmall-body eclipses. Europa transits show as a dark spot on Jupiter; a Phobos transit dims Mars's sunlight by only 26–40%.
October 1
2026-10-01- featureNight-vision goggles. Exposure amplified roughly 12x for the lunar dark.
- featureShadows between bodies. Body-to-body shadow casting, checked against the real November 8, 2022 lunar eclipse.
- artIuventius Pup drive. Ignition, full burn, cutoff and cooling for the Pup's main drive.
- fixThruster ignition transient. The ignition pop on thruster start-up is smoothed out.

August 31
2026-08-31- featureColony building. Place three buildings on Jezero Delta hex plots; they persist and you can craft with them.
