Hey it's me Destin welcome back to Smarter Every Day. Depending on where you get your media you're probably aware that we just failed for the third time in eight months to get cargo vehicles up to the International Space Station, which means that cargo didn't make it up there. Now the media's really negative about this and I understand that. It's n... Read More

Questions & Answers

Q: Why is staging important in rocket design?

Staging allows for the efficient use of propellant by dropping off heavy empty tanks, leading to increased efficiency in reaching orbit.

Q: What were the main causes of the recent rocket failures?

The failures were attributed to issues with engine refurbishment, a failure in the third stage, and an unexplained explosion during launch.

Q: How does the failure of cargo vehicles affect supplies on the International Space Station?

The failure led to a compressed schedule for resupply missions and adjustments in inventory management on the space station.

Q: How do cargo vehicles differ from human-rated vehicles?

Human-rated vehicles have additional safety measures, such as extra guidance computers, valves to isolate propellant problems, and launch abort systems.

Summary & Key Takeaways

• Rocket failures provide valuable learning opportunities for rocket engineers and mission planners.

• Staging, the process of dropping off empty propellant tanks and switching to smaller tanks, enhances the efficiency of reaching orbit.

• The recent failures include a catastrophic failure of the Orbital Sciences Antares vehicle, a failure of the Russian Progress 59 vehicle, and an explosion of the SpaceX Falcon 9 rocket.
