Edward Tsang "Ed" Lu (Chinese: 盧傑; pinyin: Lú Jié; born July 1, 1963) is an American physicist and former NASA astronaut. He flew on three Space Shuttle flights, and made an extended stay aboard the International Space Station.[1]

Key Information

In 2007, Lu retired from NASA to become the program manager of Google's Advanced Projects Team.[2][3] In 2002, while still at NASA, Lu co-founded the B612 Foundation, dedicated to protecting the Earth from asteroid strikes, later serving as its chairman.[1] As of 2020, he is its executive director.[4]

Early life and education

[edit]

Lu was born in Springfield, Massachusetts,[5] to a Taiwanese American family.[6] His parents were immigrants from Taiwan.[7] He was raised in Honolulu, Hawaii, and Webster, New York.[5]

Lu attended R. L. Thomas High School, where he was a member of the wrestling team and graduated in 1980. After high school, Lu graduated from Cornell University, where he earned his Bachelor of Science (B.S.) in electrical engineering and was a member of Pi Kappa Phi. He then earned a Master of Science (M.S.) and a Ph.D. in applied physics from Stanford University in 1989 as a fellow of the National Science Foundation.[1]

Lu became a specialist in solar physics and did postdoctoral work at the Institute for Astronomy in Honolulu, Hawaii before being selected for the NASA Astronaut Corps in 1994.[1]

NASA career

[edit]

Lu flew on Space Shuttle missions STS-84 in 1997 and STS-106 in 2000, in which he carried out a six-hour spacewalk to perform construction work on the International Space Station. Having been flight engineer on Soyuz TMA-2, Lu spent six months in space in 2003 as part of ISS Expedition 7, with cosmonaut Yuri Malenchenko.[1]

In July 2003, Lu and Malenchenko answered questions from students participating in Japan's NASDA special educational event, where Ed Lu performed "Happy Birthday" on an electronic piano for a student's birthday in the live broadcast from space.[8][9] He had demonstrated the difficulty of playing the piano instrument in space during a live in-orbit interview with CBS News and NASA TV video feed.[10] Also on this ISS mission on October 15, 2003, Lu communicated with the crewman of China's first crewed mission into space, Yang Liwei, flying aboard Shenzhou 5. Lu congratulated the Chinese for the achievement and said in Putonghua: "Welcome to space. Have a safe journey". Malenchenko added: "I love to have somebody else in space instead of (just) me and Ed".[11]

During the STS-106 mission, while on a space phone call with professor Lloyd Kaufman, Ed Lu observed that there is no moon illusion in space [12]

While still employed at NASA, Lu co-founded the B612 Foundation along with former astronaut Rusty Schweickart and scientists Clark Chapman and Piet Hut. It has conducted two lines of related research to help detect asteroids that could one day strike the Earth, and find the technological means for asteroid deflection. The foundation's current goal is to design and build a privately financed asteroid-finding space telescope, Sentinel, to be launched in 2017–2018. The Sentinel's infrared telescope, once parked in an orbit similar to that of Venus, will help identify asteroids and other near-Earth objects (NEOs) that pose a risk of collision with Earth.[1]

Magic trick in space

[edit]

While on the ISS, Lu teamed up with magician James Randi (founder of JREF) to perform a card trick in outer space. Randi asked Lu to (without looking) select a card from the middle of a brand new freshly shuffled deck of cards, turn it around and reinsert the card into the deck the opposite direction. Then place the deck of cards back into its box then take them out again and fan the cards to the camera. This same procedure was being done by Randi back on Earth at the JREF headquarters in front of witnesses from the Miami Herald. Both Randi and Lu successfully selected the same card, the seven of diamonds. The remaining cards were jettisoned for weight reasons before returning to Earth, but Lu smuggled the card home. The two cards complete with autographs are framed for public view at the JREF offices in Fort Lauderdale, FL. Randi asks Lu "What are the odds that we would both choose the same card?" Lu answers "Knowing you and your tricky ways, the odds were one in one, because it's a trick!"[13]

On August 10, 2007, Lu announced he was retiring from NASA to work at Google.[1][2]

In June 2010, Lu left Google and worked out of the Sunfire Offices.[14] In September 2011, Lu joined Liquid Robotics as Chief of Innovative Applications, where his work includes outreach to promote new applications for ocean science,[15] and in 2012, he joined Hover Inc. as its Chief Technology Officer.[16]

On June 28, 2012, Lu, with Apollo 9 Astronaut Rusty Schweickart and G. Scott Hubbard, Astronautics professor at Stanford University announced plans to build and operate the first privately-funded deep space mission called Sentinel. Their non-profit B612 Foundation will launch an infrared space telescope in orbit around the Sun, where from a distance as great as 270,000,000 kilometers (170,000,000 mi) from Earth, where it would detect and track asteroids and other near-Earth objects posing threats to the planet. On October 25, 2016, B612 and Lu endorsed NASA's NEOcam proposed mission and ended the Sentinel project.

As of 2022, Lu is working on a new project to find "killer asteroids" by analyzing terabytes of archived data. So far, the B612 Foundation, cofounded by Lu, has found over 100 new potentially-threatening asteroids. This immense number-crunching effort is supported in part by Google's applied artificial intelligence project.[17]

Ed Lu's first Space Shuttle mission was , launched aboard on May 15, 1997, where he served as a on the nine-day flight that docked with Russia's . The primary objectives included the crew exchange of astronaut Michael Foale for Jerry Linenger, who had completed 123 days aboard , along with the transfer of 7,314 pounds of water and logistics supplies between the spacecraft to support ongoing operations. During the mission, Lu contributed to microgravity science research by operating the Liquid Motion Experiment (LME) alongside mission specialist Carlos Noriega after undocking from , investigating liquid behaviors in spinning tanks to advance understanding in low-gravity environments. Lu's second Space Shuttle assignment was STS-106, again aboard Atlantis, launched on September 8, 2000, as mission specialist and payload commander during the 11-day mission dedicated to International Space Station (ISS) outfitting. This flight marked the first crewed ISS assembly mission following the 1998 launch of the Zarya control module, emphasizing logistics delivery and preparation for permanent habitation through joint U.S.-Russian efforts. The crew transferred more than 6,600 pounds of supplies and equipment from the orbiter and a docked Progress resupply vehicle to the station's Zvezda service module, installing components to enhance life support and operational capabilities. A key technical contribution on was Lu's participation in a 6-hour, 14-minute (EVA) with cosmonaut on September 11, during which they connected power, data, and communications cables between the Zvezda and Zarya modules and installed a on Zvezda to support future station functionality. Supported by the shuttle's operated by another crew member, the EVA facilitated integration and setup. These shuttle missions underscored Lu's role in precursor activities that built foundational ISS , fostering international partnerships essential for the station's assembly and long-term operations.

International Space Station expedition

Ed Lu launched to the (ISS) on April 26, 2003, aboard the Soyuz TMA-2 spacecraft as NASA's ISS Science Officer and , alongside Russian cosmonaut , who served as commander. The duo docked with the ISS on April 28, following a handover period with the departing Expedition 6 crew, marking the beginning of Expedition 7's approximately six-month residency. This mission represented a significant transition for Lu, whose prior experience on missions facilitated his adaptation to long-duration operations on the station. During Expedition 7, Lu and Malenchenko conducted a range of scientific investigations and maintenance tasks under the constraints of a reduced two-person crew, a direct result of the program's grounding after the Columbia disaster on February 1, 2003. Key experiments focused on the effects of microgravity on biological systems, including studies of cellular and chromosomal changes, responses, and space radiation risks to human health. They also performed observations, capturing images of natural phenomena such as hurricanes, and tested materials under microgravity conditions, like the behavior of air bubbles in weakening substances.
