News of the Day

Lux Aeterna, a Denver-based startup founded by former SpaceX and Amazon Kuiper engineer Brian Taylor, has raised $4 million in pre-seed funding from Space Capital and others. Lux Aeterna is developing Delphi, a reusable satellite designed to survive atmospheric reentry and land safely back on Earth, a significant departure from today’s one-and-done satellites that either burn up or retire to “graveyard” orbits. Drawing on proven NASA heat shield designs, Delphi aims to fly aboard a SpaceX Falcon 9 in 2027, with plans to scale to larger, more reusable vehicles. The project could dramatically lower satellite deployment costs and unlock a more flexible, upgradeable approach to space infrastructure — a proposition already drawing interest from the U.S. Department of Defence.

The older I get, the more I realize that it’s perfectly ok to live a life that looks confusing to others. Wake up early. Eat real foods. Go on long walks. Obsess over something. Pray. Be grateful. Read old books. Never gossip. Be loved by a few. Recipe for a good life.
