The episode features an in-depth interview with Mark Russell, CEO of General Hypersonics, who discusses groundbreaking developments in space launch systems.

2. Space Industry News

Maria begins by presenting a series of noteworthy updates from various sectors within the space industry:

• SpaceX and Vast's Research Initiative: SpaceX and Vast are actively seeking science and research proposals aimed at enabling life in space and on other planets. Selected projects will benefit from access to advanced facilities such as the Haven 1 space station and Dragon spacecraft.

• Spider Oak's U.S. Air Force Research Laboratory Contract: Spider Oak has been chosen to enhance the Space Force's capability to integrate commercial satellite networks seamlessly during emergencies. This initiative, supported by a tactical funding increase, aims to develop a secure automated control plane for the Commercial Augmentation Space Reserve Program (CAESAR), ensuring immediate access to commercial satellite resources during crises.

• IceEye and Satim Partnership: These companies are collaborating to create a new product that combines Artificial Intelligence (AI) with Synthetic Aperture Radar (SAR) satellite operations. This partnership aims to enable the detection and classification of vessels, aircraft, and land vehicles from space, with plans to release commercially available products following an initial pilot phase.

• Rocket Lab's Electron Mission for Kines: Rocket Lab successfully launched its 59th Electron mission from New Zealand, deploying five satellites for the French Internet of Things (IoT) operator Kines. This mission marks the fourth launch for Kines and contributes to building a constellation designed for real-time data transmission, supporting applications like forest fire detection and infrastructure monitoring.

• MDA Space's Contract with Globalstar: MDA Space has secured a contract valued at approximately 1.1 billion Canadian dollars to manufacture over 50 MDA Aurora software-defined digital satellites for Globalstar's next-generation Low Earth Orbit (LEO) constellation. This contract follows an initial authorization to proceed announced in November 2023.

3. Featured Interview: Mark Russell on General Hypersonics

Timestamp: [09:21] – [20:05]

Maria Varmazes conducts an insightful interview with Mark Russell, CEO of General Hypersonics, focusing on the company's innovative approach to space launch systems.

Innovative Launch System: Mark Russell introduces General Hypersonics' revolutionary launch system that utilizes a ram accelerator to propel payloads into space. Unlike traditional rockets that carry substantial fuel for propulsion, this system leverages ground-based infrastructure to impart the necessary velocity for reaching orbit.

Key Points Discussed:

• Ram Accelerator Technology ([10:11] – [10:42]):

  • The launch system employs a ram accelerator, a tubular structure resembling drill pipe, situated underground. A sharp-nosed projectile travels through compressed air and natural gas within the tube, creating and riding a shock wave to achieve high velocities upon exit.
  • Mark Russell: "It is a ramjet in the ground and the sidewalls of this steel tube. And the sharp nose projectile flies through compressed air and natural gas. In doing so, it sets up a shock wave."

• Development and Testing ([12:15] – [13:53]):

  • General Hypersonics began with small-scale prototypes, progressing from a half-inch diameter "Tabletop Ram Accelerator" to a 20-inch diameter rig at Spaceport America. Continuous refinement and breakthroughs in their labs have enabled the system to handle heavier projectiles suitable for carrying payloads into space.
  • Mark Russell: "A ramjet is the simplest jet engine. You don't need any moving parts, except in our case, the projectile."

• Operational Capabilities ([14:32] – [16:09]):

  • The system is capable of launching payloads horizontally every 90 seconds, offering a radical improvement in cost and timing for hypersonic flight.
  • Mark Russell: "So we can launch with our system horizontally every 90 seconds. It is a radical different cost and timing for what we call hypersonic flight."

• Understanding Hypersonics ([16:17] – [17:04]):

  • Russell elaborates on hypersonic speeds, defining them as five times the speed of sound (Mach 5), and explains the technological advantages and challenges associated with operating at such velocities.
  • Mark Russell: "Hypersonic means you're going five times the speed of sound. So at Mach 5, we're doing 1750 meters per second."

• Vision for the Future ([18:29] – [19:45]):

  • General Hypersonics envisions a network of waterborne drill rig platforms globally, functioning as fulfillment centers to facilitate frequent and rapid access to orbit. This approach aims to democratize space access, making it as routine as shipping an envelope.
  • Mark Russell: "You have significant payloads every few minutes. So the aggregate number of kilograms to orbit could actually be quite large with ours."

Notable Quotes:

• Mark Russell on ram accelerator simplicity: "[...] it's rocket science." ([10:53])
• On hypersonic technology impact: "DARPA tested this in the 1970s with a howitzer. And we found that if we could get funded to build something that was good for Earth first, it would actually teach us everything we needed to know." ([16:04])

4. Closing Segment: ESA's Euclid Telescope Mission

In the concluding segment, Maria Varmazes highlights the European Space Agency's (ESA) Euclid telescope mission, which has been operational since Valentine's Day last year. The mission focuses on constructing a 3D map of the universe to investigate the roles of dark matter and dark energy in cosmic formation.

Key Highlights:

• Gravitational Lensing Observations:

  • Euclid is detecting gravitational lensing events, where light from distant galaxies is distorted by the gravity of closer galaxies, creating phenomena such as Einstein Rings.
  • Maria Varmazes: "Euclid has spotted such a ring by looking at Galaxy NGC 6505, which is a mere 590 million light years from us, practically next door. But the galaxy that, to our view is forming, the ring around NGC 6505 is both unnamed and unknown, and it is 4.42 billion light years away."

• Scientific Significance:

  • Observing Einstein Rings allows astronomers to study extremely distant objects and gain insights into the distribution of dark matter and the expansion of the universe.

5. Conclusion

The episode of T-Minus Space Daily offers a comprehensive overview of current advancements in space launch technologies and AI-powered surveillance. Mark Russell's interview provides a glimpse into the future of space access through hypersonic launch systems, potentially revolutionizing how payloads are sent to orbit. Additionally, the segment on ESA's Euclid telescope underscores the ongoing efforts to unravel the mysteries of the universe's structure and expansion.
