United States Infrastructure

Most of the infrastructure of the United States (US) was constructed in the nineteenth century. Various types of infrastructure include lock chambers, dams, levees, water pipes, sewage pipes, and bridges, with an estimated average life expectancy of 50 years. As the aging infrastructures’ quality deteriorates over time, it is critical that repairs and maintenance remain consistent in order to keep us safe.

Climate change is one of the most serious infrastructure challenges the US faces today, causing crumbling bridges and water systems as a result of unprecedented rainfall, floods, and heat waves. These failures have caused widespread damage throughout the US. Infrastructure built centuries ago was not designed for the environment we have today; therefore, it is critical that the US prioritizes and funds infrastructure on a national scale.

To save our infrastructure, we must all work together to address this long-term issue. The rising costs of materials will delay repairs, and pushing forward on critical infrastructure improvements would be the first step toward having funds to combat aging infrastructure. Working together to combat climate change will additionally slow the deterioration of infrastructure.

March is overflowing with birthdays of engineers who made history in the United States, and we want to highlight the achievements of these inspiring engineers:

Kalpana Chawla was born March 17, 1962 in Karnal, India. She received a Bachelor of Science degree in aeronautical engineering in India, and later on moved to the United States to continue her education and received a Master’s degree in aerospace engineering. After being naturalized in the United States, she became an astronaut, engineer, and the first woman of Indian descent to go to space. Chawla lost her life during the Space Shuttle Columbia disaster, but her legacy continues to live on through her work. Her research helped other astronauts understand health and safety during spaceflight. She continues to be an inspiration for many immigrants who are chasing the American dream.

Robert Lee Curbeam, Jr. was born March 5, 1962. He is an African-American astronaut, engineer, military officer, and aircraft pilot. Curbeam was a Captain in the United States Navy, and during his Naval career he was deployed to many locales including the Caribbean and the Mediterranean. After completing his term, he returned as an instructor for the Weapons and Systems Engineering Department. During his NASA career, Curbeam broke the record for the astronaut with the most space walks on a single flight.

Michael Fincke was born March 14, 1967. He is an astronaut, engineer, and military officer. Fincke was a member of the United States Air Force stationed at the Air Force Base in Los Angeles, California. While in the Air Force Space and Missiles Systems Center Department, he worked as a space system and space test engineer, working on many flight test programs and holding a colonel rank. During his NASA career, Fincke held many titles, such as Mission Specialist, International Space Station Spacecraft Communicator, and Flight Engineer. During one of his missions, he broke the American record for the most time spent in space.
