What Is the Purpose of the Pentagon's Secret X-37B Space Drone?

Click For Summary

Discussion Overview

The discussion revolves around the purpose and safety measures associated with the Pentagon's secret X-37B space drone. Participants explore the implications of the protective gear used by personnel handling the drone, particularly in relation to potential hazards such as toxic propellants or radioactive materials.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question the necessity of self-contained atmospheric protective ensemble suits, suggesting they may indicate the presence of hazardous materials.
  • There is speculation about the drone possibly being powered by a small nuclear reactor, although this remains unconfirmed.
  • One participant identifies the SCAPE suit as a protective measure against toxic propellants, particularly hydrazine, which is commonly used in small thrusters.
  • Concerns are raised about the potential for a hydrazine leak, prompting the use of protective suits and detection equipment.
  • Participants mention other hazardous oxidizers that could be used as rocket fuel, highlighting the dangers associated with these materials.

Areas of Agreement / Disagreement

Participants generally agree that the protective suits are likely related to the handling of toxic substances, particularly hydrazine. However, there is no consensus on the exact reasons for the suits or the nature of the materials involved, leaving multiple competing views on the topic.

Contextual Notes

The discussion includes assumptions about the materials used in the drone and the potential risks associated with them, but these remain unresolved and speculative.

Cool article. Couple of questions: Why do they need to use self-contained atmospheric protective ensemble suits around the drone? Is that yellow object the man is carrying in the first pic a Geiger counter?

Considering that most details about this vehicle are classified, I'm my sure you will get a definitive answer.
 
You're right, but maybe someone here can give an educated guess. That attire they're wearing seems excessive unless the drone is radioactive or has some toxic coating or something. Maybe it's powered by a small nuclear reactor? I could speculate...lol.
 
The outfit the guys have on is called a SCAPE suit (Self Contained Atmospheric Protective Ensemble). The only reason I know of for wearing one is to protect you from toxic propellants, most likely hydrazine which is commonly used for those small thrusters used for attitude adjustment. They might be wearing them because they suspect a hydrazine leak and the yellow box could be something to detect it with.

I suppose it's possible that there's something radioactive on board, but I can't imagine what it could be.
 
A hydrazine leak -- definitely a good reason to wear those suits.
 
It could be hydrazine or several other extremely hazardous oxidizers used as rocket fuel. We used Chlorine trifluoride to clean chambers of process byproducts but the stuff was so dangerous we removed it after a few false alarms.

nsaspook, did you wear one of those suits?
 
Highly toxic chemical propellants may leak from the vehicle. Same thing when they received the space shuttles.

We have A level suits for the response team.

A possible fuel leak is definitely a good reason to wear those. Hydrazine specifically is insanely toxic, and even short term exposures can lead to terrible things.
