This video analyzes the second flight of Blue Origin's New Glenn rocket, mission "Never Tell Me the Odds," which successfully launched the Escapade Mars probes. The primary technical focus is the novel propulsive recovery of the first-stage booster. Key points of discussion include the rocket's ponderous liftoff due to a low thrust-to-weight ratio, the BE-4 methane engines, and an unusual pitch-up maneuver by the second stage post-separation, interpreted as a deliberate flight profile choice to ease the booster's re-entry. The analysis highlights the visually distinct bow shock during the entry burn, a consequence of the clean-burning methane fuel. The landing itself was a departure from established methods, employing a conservative hover-and-translate maneuver for a precise touchdown on the barge Jacqueline. The report concludes by examining the pyrotechnic system used to weld the booster's legs to the deck and the successful deployment of the primary payload.
Analysis of New Glenn's Second Flight and First Booster Recovery
0:00 Launch and Engine Performance: The New Glenn's second flight successfully launched the Escapade spacecraft to Mars. Its liftoff was notably slow, with a thrust-to-weight ratio comparable to the Saturn V. Its seven BE-4 methalox engines are more advanced than Falcon 9's Merlins but inferior to Starship's Raptors. It appears there is room for performance growth in these engines.
3:11 Stage Separation and Trajectory: After stage separation, the second stage executed a distinct pitch-up maneuver. This was not an anomaly but an intentional choice. By having the second stage burn more vertically to compensate for a lower-than-optimal altitude, the first stage was able to fly a less aggressive trajectory, simplifying its subsequent re-entry and landing.
6:47 Visually Distinct Entry Burn: During the three-engine entry burn, the booster created a remarkably well-defined bow shock. This is attributed to the optically thin exhaust of the methane-burning BE-4 engines, unlike the bright, obscuring flame from the kerosene-fueled Merlin engines on Falcon 9.
8:46 Conservative Landing Profile: New Glenn's landing was fundamentally different from a Falcon 9 "hoverslam." The booster targeted a point adjacent to the barge, hovered to confirm stability, and then translated horizontally to land precisely in the center. This is a propellant-intensive but safer, more conservative method that its ability to hover on a single engine enables.
9:39 Pyrotechnic Securing System: Upon landing, the booster's legs were pyrotechnically fastened to the deck using a patented system that drives studs into the ship, effectively welding it in place for stability in rough seas. These connectors are designed to be unbolted at port.
12:31 Payload Deployed: The second stage successfully reached orbit and deployed the two Escapade spacecraft. They are on a circuitous, months-long trajectory using a future Earth flyby to gain the velocity needed for their Mars transfer.
13:56 Autonomous Deck Robot: Post-landing, an autonomous robot connects umbilicals to the booster to safe it and offload remaining propellant before human crews can approach.
15:06 A Successful Recovery: Blue Origin is now the third American company to recover an orbital-class booster, and the second to do so via propulsive landing. The success was the result of deliberate engineering choices, not luck.
