New Glenn NG2 Launch Attempt and Mission Overview

This video covers the second launch attempt (NG2) of Blue Origin's New Glenn rocket. The primary objectives of this mission are:

Safely deploy NASA's Escapade payload: Two satellites designed to study Mars' atmosphere and magnetosphere.
Successfully land the reusable first stage (booster) for the first time.

The launch window opened at 2:57 PM Eastern Time and concluded around 4:25 PM. The mission is designed to be a cost-effective ride for NASA, with the Escapade satellites utilizing their own propulsion to reach Mars from a Lagrange point.

New Glenn: Capabilities and Design

New Glenn is a massive rocket, standing 95 meters tall, making it comparable in scale to the Saturn V. It is significantly larger than the Falcon 9 and even rivals the Falcon Heavy in capability.

Payload: Rated for 45 tons to low Earth orbit with a reusable booster. While technically expending the entire rocket could yield around 60-65 tons (similar to Falcon Heavy), Blue Origin intends to fly New Glenn with reusability in mind.
Propellants:
- First Stage (Booster): Uses liquid methane and liquid oxygen (Methalox), powered by seven BE-4 engines.
- Second Stage: Uses liquid hydrogen and liquid oxygen (Hydrolox), powered by two BE-3U engines. This combination offers high performance for upper stage operations.
Engines:
- BE-4: Produces approximately 550,000 lbs of thrust each.
- BE-3U: Operates on a bleed expander cycle, providing around 445 seconds of specific impulse, which is high-performing but slightly less efficient than a closed expander cycle like the RL10. The BE-3U engines are designed for higher thrust to compensate for the massive second stage.
Reusability: The primary focus for the first stage is propulsive landing on a drone ship named "Jaclyn," located approximately 375 miles offshore. Unlike some other landing strategies, New Glenn is not currently planned for land landings (RTLS).
Size Comparison: New Glenn's 7-meter diameter places it between Falcon 9/Vulcan and Starship. Its 95-meter height is comparable to Saturn V.

Mission Profile and Flight Events

The NG2 mission followed a detailed flight profile:

Liftoff: Seven BE-4 engines ignite, generating 3.8 million pounds of thrust.
Supersonic Ascent: The rocket goes supersonic around 40,000 ft (12 km).
Max Q: The vehicle experiences maximum dynamic pressure around 40,000 ft.
Boost Phase End & Stage Separation: Approximately 3 minutes into flight, the first stage engines shut off (MECO - Main Engine Cutoff), and the first stage separates from the second stage.
Booster Re-entry Burn: The first stage reorients itself and performs a re-entry burn to slow down.
Booster Landing Burn: The booster fires its engines for a final landing burn to touch down on the "Jaclyn" drone ship.
Second Stage Burn: The two BE-3U engines ignite to propel the payload into orbit.
Fairing Jettison: At approximately 400,000 ft (120 km), the payload fairings protecting the satellites are jettisoned.
Payload Deployment: The Escapade satellites are deployed approximately 38 minutes into flight, 30 seconds apart.
Viasat Tech Demo Activation: A Viasat technology demonstration payload activates around 38 minutes into flight.

Launch Attempt and Hold

The launch attempt experienced a hold at T-minus 20 seconds due to a "terminal count abort." The team investigated the issue, and after a period of investigation, the clock was reset to T-minus 19 minutes and 45 seconds, indicating a successful resolution and continuation of the countdown. The hold was described as a normal part of early rocket development, with companies like SpaceX also experiencing numerous scrubs in their early days.

Key Arguments and Perspectives

Competition and Progress: The video emphasizes that New Glenn's success is beneficial for the entire space industry, fostering competition and driving innovation. It argues against a tribalistic approach to space exploration, encouraging excitement for all successful launches.
Scale and Capability: A recurring theme is the sheer size and capability of New Glenn, which is often underestimated. The presenter uses comparisons to other rockets and personal experiences to illustrate its massive scale.
Reusability as a Goal: The successful landing of the booster is highlighted as a critical milestone, demonstrating Blue Origin's commitment to reusable rocket technology.
Cost-Effectiveness of Escapade: The NASA Escapade mission is noted as being remarkably inexpensive for an interplanetary mission, showcasing the potential for cost-effective space exploration.
YouTube Algorithm Challenges: The presenter expresses frustration with YouTube's algorithm, which he feels prioritizes short-form content and can hinder the visibility of long-form educational videos. This is a reason for his involvement with Nebula.
