Early life and education

Chen is from Newtown, PA, [2] and is a graduate of The 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. [1] Chen was on the varsity fencing team, competing in the sabre. [3] [4] 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. [2]

In graduate school, he was in the Space Systems Laboratory (MIT) with Professor Dave Miller. He worked on propulsion system for the Synchronized Position Hold Engage and Reorient Experimental Satellite (SPHERES) project.

Chen received a Fully Employed Master of Business Administration (FEMBA) from the UCLA Anderson School of Management in 2007. [5]

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. [6] 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. [7] [8]

He was a member of the MSL EDL team to accept the National Air and Space Museum Trophy in person. [9] He joined team members for a GQ profile. [10]

Chen joined the Mars 2020 team in 2013, shortly after the team was assembled. [11] 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. [1] [12] 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. [13] [14] [15]

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. [1]

Selected publications

Personal life

Chen is married to NASA JPL systems engineer Julie Wertz Chen. [16] They met at MIT and were both in the SPHERES Capstone class. [17] Julie Wertz Chen was on the Mars InSight landing team [18] and sat in the same front row seat that he did for Curiosity. [1]

Chen has been active on social media since before the MSL landing. [19]

A Mars rover is a motor vehicle designed to travel on the surface of Mars. Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very remote robotic vehicle control. They serve a different purpose than orbital spacecraft like Mars Reconnaissance Orbiter. A more recent development is the Mars helicopter.

Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. The rover carries a variety of scientific instruments designed by an international team.

<span class="mw-page-title-main">Jezero (crater)</span> Crater on Mars

Jezero is a crater on Mars in the Syrtis Major quadrangle, about 45.0 km (28.0 mi) in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. The lake in the crater was present when valley networks were forming on Mars. Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake inside the crater probably formed during a period in which there was continual surface runoff.

The embedded computer systems onboard Mars rovers are designed to be robust against withstand high radiation levels and large temperature changes in space. For this reason their computational resources are more yet limited compared to systems commonly used on Earth.

<span class="mw-page-title-main">Mars atmospheric entry</span> Entry into the atmosphere of Mars

Mars atmospheric entry is the entry into the atmosphere of Mars. High velocity entry into Martian air creates a CO2-N2 plasma, as opposed to O2-N2 for Earth air. Mars entry is affected by the radiative effects of hot CO2 gas and Martian dust suspended in the air. Flight regimes for entry, descent, and landing systems include aerocapture, hypersonic, supersonic, and subsonic.

<i>Curiosity</i> (rover) NASA robotic rover exploring the crater Gale on Mars

Curiosity is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA's Mars Science Laboratory (MSL) mission. Curiosity was launched from Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC. The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover's touchdown target after a 560 million km (350 million mi) journey.

The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) is a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis. This was the first experimental extraction of a natural resource from another planet for human use. The technology may be scaled up for use in a human mission to the planet to provide breathable oxygen, oxidizer, and propellant; water may also be produced by combining the produced oxygen with hydrogen.
