What happened

Nitrogen is a key nutrient because it fuels the growth of plankton, which forms the basis of the marine food web.

Two opposing processes determine the global nitrogen cycle: nitrogen fixation and denitrification.

Key facts

  • Reported by Phys.org and published Fri, 18 Sep 2026 00:00:05 UTC.

Why it matters

Research findings and mission results set the evidence base that policy, funding and later discoveries build on.

What to watch next

  • Peer review status and replication of the findings
  • Mission milestones and next scheduled attempt
  • Funding or policy decisions that follow
