Antarctica developed a continental-scale ice sheet 34 million years ago while Earth was about 5°C warmer than today — helped by slow-moving mantle waves that had spent more than 100 million years lifting its interior high enough for permanent ice to surviv - Space Daily

A 2026 modelling study links East Antarctica’s high plateau to mantle processes begun during Jurassic breakup, while retaining falling carbon dioxide as the main trigger for glaciation.

Antarctica did not wait for Earth to become as cold as it is today. At the Eocene-Oligocene transition about 34 million years ago, ice expanded across East Antarctica while global temperature was sti… [+10283 chars]

During the Solar System’s first million years, its earliest outer worlds formed from material that was up to 92 percent heat-forged rock, while gas flowing through the young system filtered out much of the surrounding ice-rich dust. - Space Daily

NASA budgeted 200 kilograms of fuel for Roman’s first course correction, but the telescope used only 18. Combined with extra fuel loaded before launch and further expected savings, that could stretch its 10-year fuel plan to at least 22 years. - Space Daily
