5 Myths About Becoming an Astronaut

Have you ever wondered if you have what it takes to become a NASA Astronaut? The term “astronaut” derives from the Greek word meaning “space sailor,” and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond.

We’re looking for a new class of astronauts to join the NASA team, and here are a few things to know.

Here are a few myths about becoming an astronaut:

MYTH: All astronauts have piloting experience.

FACT: You don’t need to be a pilot to be an astronaut. Flying experience is not a requirement, but could be beneficial to have.

MYTH: All astronauts have perfect vision.

FACT: It’s okay if you don’t have 20/20 vision. As of September 2007, corrective surgical procedures of the eye (PRK and LASIK), are now allowed, providing at least 1 year has passed since the date of the procedure with no permanent adverse after effects.

MYTH: All astronauts have advanced degrees like, a PhD.

FACT: While a Bachelor’s degree from an accredited university is necessary, an advanced degree is not required to become an astronaut.

MYTH: Astronauts are required to have military experience in order to be selected.

FACT: Military experience is not required to become an astronaut.

MYTH: You have to be a certain age in order to be an astronaut. 

FACT: There are no age restrictions. Astronaut candidates selected in the past have ranged between the ages of 26 and 46, with the average age being 34.

Okay, but What are the requirements?

Commander and Pilot Astronauts

Pilot astronauts serve as International Space Station commanders and pilots. During flight, the commander has onboard responsibility for the vehicle, crew, mission success and safety of flight. The pilot assists the commander in controlling and operating the vehicle.

Basic requirements for an Astronaut Pilot include the following:

Bachelor’s degree from an accredited institution in engineering, biological science, physical science or mathematics. An advanced degree is desirable. Quality of academic preparation is important.

At least 1,000 hours pilot-in-command  time in jet aircraft. Flight test experience is highly desirable.

Ability to pass a NASA space physical which is similar to a military or civilian flight physical and includes the following specific standards:

Distant visual acuity: 20/100 or better uncorrected, correctable to 20/20, each eye Blood pressure: 140/90 measured in a sitting position Height between 62 and 75 inches

Mission Specialist Astronauts

Mission specialist astronauts work with the commander and the pilot and have overall responsibility for coordinating operations in the following areas: systems, crew activity planning, consumables usage and experiment/payload operations.

Basic requirements for a Mission Specialist include the following:

Bachelor’s degree from an accredited institution in engineering, biological science, physical science or mathematics. Degree must be followed by at least three years of related, progressively responsible experience. An advanced degree is desirable and may be substituted for part or all of the experience requirement. Quality of academic preparation is important

Ability to pass a NASA space physical which is similar to a military or civilian flight physical and includes the following specific standards:

Distant visual acuity: 20/200 or better uncorrected, correctable to 20/20, each eye Blood pressure: 140/90 measured in a sitting position Height between 58.5 and 76 inches

Traveling to Mars (safely AND quickly) with plasma rockets

There has been quite a bit of hype about getting people to Mars. But traveling 35 million miles to the red planet will require a new breed of rockets that are much more powerful and efficient than traditional chemical-fueled rockets.

It takes *A LOT* of fuel to get into space. The Saturn V, which launched spacecraft to the moon, required fuel tanks that were taller than the Statue of Liberty. Traveling to Mars, which is 200 times farther than the moon, means that we would need to build an even bigger rocket that can carry 200 times more fuel — a highly impractical quest. 

So NASA researchers are working on a new kind of rocket with electric thrusters that can travel at high speed using less fuel. These plasma rockets can get spacecraft to the moon with one-tenth the tank of fuel used by Saturn V, and are capable of cutting a risky trip to Mars down from two years to less than two months. 

Even though plasma rockets are ideal for long-term spaceflight, they do have some shortcomings.

To create plasma, a gas-like matter that’s as hot as the sun, radio waves are used to heat a gas propellant. The problem is that during the heating process, charged ion particles are expelled, causing damage to the thruster’s walls that could potentially lead to a catastrophe.

So what if there was a way that the wall could repair itself?

Gary Li, a UCLA aerospace engineering grad student, is figuring out a way to do just that. In the video below, he explains how his research could help humans travel safely and quickly to Mars:

The real battle is who can stare each other down the longest.

We’re With You When You Fly

Did you know that “We’re With You When You Fly”? Thanks to our advancements in aeronautics, today’s aviation industry is better equipped than ever to safely and efficiently transport millions of passengers and billions of dollars worth of freight to their destinations. In fact, every U.S. Aircraft flying today and every U.S. air traffic control tower uses NASA-developed technology in some way. Here are some of our objectives in aeronautics:

Making Flight Greener

From reducing fuel emissions to making more efficient flight routes, we’re working to make flight greener. We are dedicated to improving the design of airplanes so they are more Earth friendly by using less fuel, generating less pollution and reducing noise levels far below where they are today.

Getting you safely home faster

We work with the Federal Aviation Administration to provide air traffic controllers with new tools for safely managing the expected growth in air traffic across the nation. For example, testing continues on a tool that controllers and pilots can use to find a more efficient way around bad weather, saving thousands of pounds of fuel and an average of 27 minutes flying time per tested flight. These and other NASA-developed tools help get you home faster and support a safe, efficient airspace.

Seeing Aviation’s Future

Here at NASA, we’re committed to transforming aviation through cutting edge research and development. From potential airplanes that could be the first to fly on Mars, to testing a concept of a battery-powered plane, we’re always thinking of what the future of aviation will look like.
