Chris Kemp took Astra public in 2021 with a bold vision: low-cost rockets launching daily, bringing sovereign space access to every country on Earth. At its peak, the company was worth over $2 billion. Within two years, that valuation collapsed by 99%.

In this episode of Valley of Depth, we go inside one of the most dramatic flameouts and attempted comebacks in the commercial space era. We discuss:

• Why Astra’s SPAC-era promises didn’t survive contact with reality
• What really went wrong with Rocket 3 and how much of that falls on Kemp
• The decision to take the company private and buy it back for pennies on the dollar
• How Astra raised $80M, and its attempt to raise another $100M+
• The quiet success of its satellite propulsion business
• Rocket 4, and whether this time is actually different
• How Kemp is repositioning Astra as a mobile, defense-aligned launch platform
