Allen Chen

Allen "Al" Chen is an American aerospace engineer. He was the Entry, Descent, and Landing (EDL) Operations Lead on the Mars Science Laboratory mission and the EDL Lead for the Mars 2020 mission.

Early life and education Chen is from Newtown, Pennsylvania, and is a graduate of Lawrenceville School. He is a fan of the Philadelphia Eagles and Phillies teams.

He decided on the aerospace field during the spring of his freshman year at Massachusetts Institute of Technology. As a senior, he received the David J. Shapiro Memorial Award for building an electric-powered model aircraft with seven other students. He also received the James Means Memorial Award for Excellence in Flight Vehicle or Space Systems Engineering for his contributions to the SPHERES project in the "Conceive, Design, Implement and Operate" Capstone course.

Work at NASA

Allen Chen has worked at NASA's Jet Propulsion Laboratory in Pasadena, California for his entire career. He joined the Mars Science Laboratory EDL team in 2002. On August 5, 2012, Chen announced "Touchdown confirmed. We're safe on Mars!," after which the JPL Mission Control Center erupted in celebration; team members hugged, high fived, clapped and cried.

He was a member of the MSL EDL team to accept the National Air and Space Museum Trophy in person. He joined team members for a GQ profile.

Chen joined the Mars 2020 team in 2013, shortly after the team was assembled. In his EDL lead role, he was responsible for ensuring the spacecraft traveled safely from the top of the Martian atmosphere to landing in Jezero crater. The coronavirus pandemic broke out a year before the landing, so Chen had to lead his team while keeping socially distant and maintaining COVID-19 protocols.

Chen narrated the Mars 2020 landing procedures with Guidance and Controls Operations Lead Swati Mohan on February 18, 2021. Chen stated he's excited to be a part of bringing Martian samples back to Earth. He considers his Mars 2020 EDL team to be a second family to him. They met at MIT and were both in the SPHERES Capstone class. Julie Wertz Chen was on the Mars InSight landing team and sat in the same front row seat that he did for Curiosity.
