Video: 00:08:29 Focus on Euclid with Laurent Brouard: “I’m going to show you what a telescope that we send into space looks like.”
Laurent Brouard, Project Manager at Airbus Defence and Space, was responsible for building the Euclid payload module (PLM).
In this interview, which took place in a clean room at the Airbus premises in Toulouse, he describes with words, gestures, and the Euclid PLM structural and thermal model how Euclid works.
Did you know that Euclid sees the same part of the sky at the same time in both the infrared and visible wavelengths? Or that in space radiators keep the instruments cold? Have you ever wondered how light “travels” inside Euclid’s telescope?
Listen to Laurent to know more about the technology behind the mission that will map the dark matter and the dark energy of the Universe.

NASA Astronaut Mary L. Cleave. April 8, 1985NASA Retired NASA astronaut Mary Cleave, a veteran of two NASA spaceflights, died Nov. 27. She was 76. A scientist with training in civil and environmental engineering, as well as biological sciences and microbial ecology, Cleave was the first woman to serve as an associate administrator for NASA’s Science Mission Directorate.
Born in Southampton, New York, Cleave received a Bachelor of Science degree in biological sciences from Colorado State University, Fort Collins, in 1969, and Master of Science in microbial ecology and a doctorate in civil and environmental engineering, both from Utah State University, Logan, in 1975 and 1979, respectively.
“I’m sad we’ve lost trail blazer Dr. Mary Cleave, shuttle astronaut, veteran of two spaceflights, and first woman to lead the Science Mission Directorate as associate administrator,” said NASA Associate Administrator Bob Cabana. “Mary was a force of nature with a passion for science, exploration, and caring for our home planet. She will be missed.”
Cleave was selected as an astronaut in May 1980. Her technical assignments included flight software verification in the SAIL (Shuttle Avionics Integration Laboratory), spacecraft communicator on five space shuttle flights, and malfunctions procedures book and crew equipment design.
Cleave launched on her first mission, STS-61B, aboard space shuttle Atlantis on Nov. 26,1985. During the flight, the crew deployed communications satellites, conducted two six-hour spacewalks to demonstrate space station construction techniques, operated the Continuous Flow Electrophoresis experiment for McDonnell Douglas and a Getaway Special container for Telesat and tested the Orbiter Experiments Digital Autopilot.
Cleave’s second mission, STS-30, which also was on Atlantis, launched May 4, 1989. It was a four-day flight during which the crew successfully deployed the Magellan Venus exploration spacecraft, the first planetary probe to be deployed from a space shuttle. Magellan arrived at Venus in August 1990 and mapped more than 95% of the surface. In addition, the crew also worked on secondary payloads involving indium crystal growth, electrical storms, and Earth observation studies.
Cleave transferred from NASA’s Johnson Space Center in Houston to the agency’s Goddard Space Flight Center in Greenbelt, Maryland in May 1991. There, she worked in the Laboratory for Hydrospheric Processes as the project manager for SeaWiFS (Sea-viewing, Wide-Field-of-view-Sensor), an ocean color sensor which monitored vegetation globally.
In March 2000, she went to serve as deputy associate administrator for advanced planning in the Office of Earth Science at NASA’s Headquarters in Washington. From August 2005 to February 2007, Cleave was the associate administrator for NASA’s Science Mission Directorate where she guided an array of research and scientific exploration programs for planet Earth, space weather, the solar system, and the universe. She also oversaw an assortment of grant-based research programs and a diverse constellation of spacecraft, from small, principal investigator-led missions to large flagship missions.
Cleave’s awards included: two NASA Space Flight medals; two NASA Exceptional Service medals; an American Astronautical Society Flight Achievement Award; a NASA Exceptional Achievement Medal; and NASA Engineer of the Year.
Cleave retired from NASA in February 2007.

NASA’s Hubble Space Telescope Pauses Science Due to Gyro Issue
Hubble orbiting more than 300 miles above Earth as seen from the space shuttle. NASA NASA is working to resume science operations of the agency’s Hubble Space Telescope after it entered safe mode Nov. 23 due to an ongoing gyroscope (gyro) issue. Hubble’s instruments are stable, and the telescope is in good health.
The telescope automatically entered safe mode when one of its three gyroscopes gave faulty readings. The gyros measure the telescope’s turn rates and are part of the system that determines which direction the telescope is pointed. While in safe mode, science operations are suspended, and the telescope waits for new directions from the ground.
Hubble first went into safe mode Nov. 19. Although the operations team successfully recovered the spacecraft to resume observations the following day, the unstable gyro caused the observatory to suspend science operations once again Nov. 21. Following a successful recovery, Hubble entered safe mode again Nov. 23.
The team is now running tests to characterize the issue and develop solutions. If necessary, the spacecraft can be re-configured to operate with only one gyro. The spacecraft had six new gyros installed during the fifth and final space shuttle servicing mission in 2009. To date, three of those gyros remain operational, including the gyro currently experiencing fluctuations. Hubble uses three gyros to maximize efficiency, but could continue to make science observations with only one gyro if required.
NASA anticipates Hubble will continue making groundbreaking discoveries, working with other observatories, such as the agency’s James Webb Space Telescope, throughout this decade and possibly into the next.
Launched in 1990, Hubble has been observing the universe for more than 33 years. Read more about some of Hubble’s greatest scientific discoveries.

Announcing the New Heliophysics Division Director
November 29, 2023
NASA has selected Dr. Joseph Westlake to fill the position of Heliophysics Division Director. Joe will join the Science Mission Directorate and assume his new role on Jan. 16, 2024.
I am pleased to have Joe take on the role as the Heliophysics Division Director. Joe has a strong background in heliophysics and planetary science and has already made significant contributions to our efforts by supporting several NASA missions including the Magnetospheric Multiscale mission, the Van Allen Probes, Parker Solar Probe, the Interstellar Boundary Explorer mission, the Juno mission, Cassini and the European Space Agency’s Juice mission to Ganymede.
Joe brings with him more than 18 years of scientific, technical, management, and programmatic experience in heliophysics, astrophysics, and planetary science. He is coming to us from the Johns Hopkins University Applied Physics Laboratory (JHUAPL) where he works as a researcher and project scientist for the Interstellar Mapping and Acceleration Probe mission and principal investigator for the Plasma Instrument for Magnetic Sounding, or PIMS, instrument destined for Jupiter’s moon, Europa, onboard the Europa Clipper mission.
“I’m very excited to join NASA as the Division Director for Heliophysics,” said Westlake. “I look forward to diving in and working with the vibrant community of scientists and engineers that are uncovering the mysteries of our star.”
In 2024, the National Academies will release a new Decadal Survey that lays out a strategy to advance scientific understanding of the Sun, Sun-Earth connections and the origins of space weather, the Sun’s interactions with other bodies in the solar system, the interplanetary medium, and the interstellar medium; Joe’s experience across several scientific disciplines, as well as his leadership and technical experience, uniquely qualifies him for this critical leadership position in the Science Mission Directorate as we embark on an exciting new decade of solar and space physics.
I extend my sincere appreciation to Peg Luce who led the Division for nearly a year while the director position was vacant; she has done a stellar job. With nearly 10 years as the deputy director, Peg’s exceptional efforts have brought significant strides within Science Mission Directorate and the broader scientific community. I am thrilled she will continue serving as the Heliophysics Division Deputy Director and helping Joe usher the division into this new era.
“The Sun touches everything and the science of heliophysics is helping us unlock its mysteries,” said Peg Luce, deputy division director, Heliophysics Division at NASA Headquarters in Washington. “Joe’s unique experience and insight will help guide the division as we usher in solar max, launch a host of new heliophysics missions, and flow through the Heliophysics Big Year.”
Please join me in welcoming Joe to Headquarters!
