S.1Abstract

Space and orbital infrastructure matters to the Nexus programme because other infrastructure now depends on it. Navigation, timing, communications and Earth observation are delivered from orbit, and the orbits are filling up. The US Space Surveillance Network had catalogued 34,054 objects in Earth orbit on 4 August 20264, and a public tracker counted 17,099 active satellites on 26 October 20263. ESA reports more than 300 launches and over 4,000 new payloads in 20252. The hazard grows with the traffic. ESA estimates more than 50,000 debris objects larger than 10 cm at the end of 20241. A geomagnetic storm of the highest class in May 2024 raised drag on thousands of satellites7, and a preprint estimates that the time to a possible catastrophic collision, if satellites stopped maneuvering, fell from 164 days in 2018 to 5.5 days in June 20259. The ground depends on orbit. A 2019 study sponsored by NIST estimates USD 1.4 trillion of private-sector benefit from GPS in the United States between 1984 and 201715, and a 2022 cyberattack on a satellite network disrupted service in Ukraine and wind farms in central Europe20. Rules are moving. The FCC adopted a five-year disposal rule in 202211, and the EU Space Act proposal of June 2025 was still under Council scrutiny in November 202514. The atmospheric footprint of reentry is only starting to be measured10. This baseline sets out what the evidence supports and where it is thin. It forecasts no collision or launch date and ranks no country or operator.

S.2Key messages

Six readings that frame the space baseline, and the eight questions this edition answers, each with its status and source.

  1. The US network catalogued 34,054 on 4 August 2026. ESA counts about 40,000 tracked at the end of 2024. The bases differ.41

    How many objects are in orbit?Reported

  2. 17,099 on 26 October 2026 in a public tracker, about two thirds from one constellation.3

    How many satellites are active?Reported

  3. ESA estimates over 50,000 objects above 10 cm and over 1.2 million above 1 cm.1

    How much debris is there?Reported

  4. It raised drag on thousands of satellites and put one NASA mission in safe mode.7

    What did the 2024 storm do?Reported

  5. A preprint estimates 5.5 days if maneuvering stopped, as of June 2025.9

    How fast could a collision cascade start?Reported

  6. GPS: a study estimates USD 1.4 trillion of US private-sector benefit from 1984 to 2017.15

    What on the ground depends on orbit?Reported

  7. A five-year disposal rule in the US from 2022; the EU Space Act proposal was under review in 2025.1114

    What do the rules require?Reported

  8. Loss of control or navigation in a crowded orbit during a severe storm. SCN-XT18-STM-01

    What will 2027 test first?Expert input

S.3Headline finding

ReportedEQL 4NRF-XTECH-SPACE-GLOBAL-2026-BASELINE-ORB-001

The US Space Surveillance Network catalogued 34,054 objects in Earth orbit on 4 August 2026.

Source: NASA Orbital Debris Quarterly News, September 20264. Each bar counts catalogued objects; the bars sum to 34,054.

The catalogue is the shared base for traffic safety, and it is incomplete by design: it holds objects large enough to track. NASA states that millimeter-sized debris numbers about 100 million and is estimated statistically5. ESA counts about 40,000 tracked objects and estimates more than 1.2 million larger than 1 cm1. The counts use different bases and are not reconciled in this edition.

S.5What each steward reads in it

GCRI · KEY T

Technical Truth

The evidence supports reading orbit as shared physical infrastructure under growing load.

GRF · KEY M

Public Meaning

For most people space arrives as a launch video, a navigation app or a headline about debris.

GRA · KEY F

Capital Meaning

Readiness implications only. The GPS benefit estimate and the 2024 farm losses show where finance-readiness evidence will matter.

NEXUS

Synthesis

Orbital infrastructure is well described by catalogue counts and thinly measured as a system.

S.6What this edition is, and is not

What this edition is

A baseline: the 2026 state of space and orbital infrastructure and the couplings through which it carries risk into other systems. It synthesises published evidence and ranks no country, company or asset.

What it is not

Not a forecast of any collision, launch or storm, an ordering of countries or operators, an endorsement of any vendor or an assessment of any programme. Licensing, spectrum, traffic rules and funding are decisions of competent authorities.

What comes next

National, regional and sector evidence feeds the 2027 space edition through the federation. Each edition reports what changed against this baseline: observations, source revisions, method changes, scenario updates and corrections.
