Kosmos 252

 1968-097A

---

The second interception of Kosmos-248 was by Kosmos-252, which flew a similar profile with a successful radar-guided intercept on the second revolution. TLE analysis suggests that the IS was injected into intermediate orbit at 500 km, and then into the intercept orbit after one orbit.
