New Glenn Carries NASA’s ESCAPADE Mars Probes to Space
Why in the news
Blue Origin’s heavy rocket New Glenn flew for the second time and sent NASA’s ESCAPADE twin probes towards Mars, also landing its first stage at sea for the first time.
Key facts
- New Glenn: 98 m, partially reusable heavy-lift rocket by Blue Origin; second flight on 13 November 2025 from Cape Canaveral.
- First flight was in January 2025: reached orbit but the booster was lost on landing.
- ESCAPADE: twin craft Blue and Gold (made by Rocket Lab); science team headed by UC Berkeley under SIMPLEx.
- Mars departure in late 2026, arrival 2027, after loitering near Sun-Earth L2.
| Item | New Glenn (rocket) | ESCAPADE (payload) |
|---|---|---|
| Maker / lead | Blue Origin (Jeff Bezos) | Led by UC Berkeley; spacecraft by Rocket Lab |
| Key features | Seven BE-4 methane-oxygen engines on first stage; two BE-3U hydrogen engines on upper stage; 7 m fairing | Magnetometers, plasma analysers, Langmuir probe on each spacecraft |
| Capacity / count | About 45 tonnes to low Earth orbit; booster designed for 25 reuses | Two spacecraft in formation |
| Milestone | Second flight; first NASA launch; sea landing | Mars arrival in 2027 |
Mission purpose
- Learn how the solar wind strips Mars’ atmosphere and the role of its weak, patchy magnetosphere.
- Take the earliest two-location, same-moment readings of the Martian magnetosphere, telling spatial change apart from change over time.
- Trace long-term atmospheric evolution (why a wetter world dried) and aid future human missions and climate modelling.
Why it matters
- Gives NASA and commercial users a second reusable heavy rocket besides SpaceX, alongside ULA’s Vulcan.
- Shows planetary science can be done cheaply through the SIMPLEx model.
- Like Falcon 9, New Glenn now has a booster recovered after an orbital launch.
Rocket comparison
- Falcon Heavy uses three Falcon 9 cores; New Glenn has one much larger core and a hydrogen-fuelled upper stage.
Exam angle
- ESCAPADE = Escape and Plasma Acceleration and Dynamics Explorers.
- SIMPLEx = Small Innovative Missions for Planetary Exploration.

- Rocket named after astronaut John Glenn.
