Key Contributions and Accomplishments:

Orion Launch Abort System (LAS), Flight Test Article (FTA), and Ares spacecraft. Verified requirements, interfaces.

Performed risk management and mitigation.

Developed vibro-acoustic test plans for LAS Remote Data Acquisition Units (RDAUs) and participated in review of test data.

Served as Lead Engineer of Mechanical Ground Support Equipment for Pad and Ascent Abort vehicles.

Let’s Learn AboutROCKET SCIENCE!

How does it GO?What SLOWS it down?

How does it STOP?

Rocket Transportation Most rockets today operate with either solid or liquid propellants. The word propellant does not mean simply fuel, as you might think; it means

FUEL + OXIDIZER

The fuel is the chemical the rocket burns but, for burning to take place, an oxidizer (typically oxygen) must be present. Jet engines draw oxygen into their engines from the surrounding air.

Rockets do not have the luxury that jet planes have; they must carry the oxidizer with them into space where there is no air.

Rocket PayloadThe Ares I Crew Launch VehicleNASA is developing hardware and systems for the Ares I rocket that will send future astronauts into orbit and one day carry crewed missions back to the Moon, on to Mars, and out to other destinations in the solar system.

Ares I is designed to carry crews of four astronauts in Orion for missions to the Moon,

Ares I was also designed to use its 26-ton payload capacity to deliver six astronauts or supplies to the International Space Station.

1 ton = 2,000 lbs

26 tons = ??? lbs

Rocket LandersDrag is a force. The common parachute relies on drag to float the parachutist safely down to earth. In the air, or even in the water, the larger the surface area of any object the more drag force will be pushing back against it as the object moves (or falls) through the air.

If a person drops out of a plane, and they stretch out, flat, as they fall through the air they’ll feel the drag force pushing up against them. If they change their position to balled-up, they’ll feel less force pushing back against them because there is less surface area for the air to push back against.
