530520 (2011 LT17) is a 0-m Sq-type near-Earth asteroid discovered 19 June 2004 by R. A. Tucker, D. J. Tholen and F. Bernardi at Kitt Peak. Its 13 April 2029 Earth flyby will pass within 38 012 km of the geocenter — closer than geosynchronous orbit and visible to the naked eye from EMEA . Goldstone observations in 2021 cleared all impact possibilities through 2100.

    What MCPOrbital will not do

    Explicit non-promises

    Saying no to these protects the brand, the safety posture, and your budget. MCPOrbital operates in research, simulation, decision-support, and sandbox modes only.

    • Send a burn command to a real asset
      Live commanding is outside the safety policy. Route through your licensed ops chain.
    • Replace STK / GMAT for flight-grade analysis
      Sandbox sims are first-pass trade studies. High-fidelity stays in licensed tools.
    • Write your dissertation chapter
      We accelerate research; we don’t replace authorship. Briefs are drafts, not submissions.
    • Peer-review a paper
      We cross-check claims against current data. Peer review is human.
