# Space-Track.org: a clean 401 JSON refusal for unauthenticated queries, but the login endpoint itself answers 200 without a POST

**What it is.** `www.space-track.org` is the authoritative US-government TLE/GP source
behind CelesTrak's and N2YO's public mirrors; it requires an account and a session
cookie obtained via `POST /ajaxauth/login`. This lane sent **no POST** to it (rule 14)
— only GET, to observe the keyless refusal shape and whether any part of the auth
surface answers to GET at all.

**Unauthenticated data query is a clean, typed 401:**
```
GET /basicspacedata/query/class/gp/NORAD_CAT_ID/25544/format/json
```
→ `HTTP/2 401 application/json`, `cache-control: no-store, no-cache, must-revalidate`:
```json
{"error":"You must be logged in to complete this action"}
```
One field, no code, no `WWW-Authenticate` header — every refusal across this entire
lane's ten sources used a different vocabulary for "you're not authenticated," and
this is yet another one: a bare English sentence under a generic `error` key.

**`GET /ajaxauth/login` (the login *endpoint itself*, no credentials, no POST) answers
`HTTP 200`** with `{"Login":"Untried"}` — a session-status probe disguised as the same
path the POST goes to; it never 4xxs, it just reports that no login attempt has been
made on this (fresh) session cookie. Both calls set a new `chocolatechip` session
cookie, `Max-Age=7200` (2-hour session TTL), even though no credentials were ever
supplied — the cookie exists before you are allowed to do anything with it.

`robots.txt` is a short, unremarkable disallow-list (`/cgi-bin/`, `/tmp/`,
`/arrowchat/`, `/assets/`, `/system/`) — no API paths are blocked from crawling, only
legacy app internals.

Probe:
```
curl -s -D- 'https://www.space-track.org/basicspacedata/query/class/gp/NORAD_CAT_ID/25544/format/json'   # 401 {"error":"You must be logged in..."}
curl -s -D- 'https://www.space-track.org/ajaxauth/login'                                                 # 200 {"Login":"Untried"}
curl -s https://www.space-track.org/robots.txt
```

How observed: 2026-10-05, curl 8 (contact User-Agent), ~07:50 UTC, three live GETs
against `www.space-track.org`; no credentials, no POST, no account held or created.
