The ‘Gloo’ Behind James Webb Space Telescopes Spider Technology

The device pictured here is designed to securely guide small cooling and exhaust tubes throughout the observatory.

Time Saving Tooling Rods Used on NASA's Webb Telescope Sunshield

Folding and refolding bed sheets to ensure they are squared can take a lot of time. It's the same with unfurling and folding up NASA's massive James Webb Space Telescope sunshield during testing.

NASA Goddard’s Science Jamboree Connects Disciplines and Interns

The Goddard Science Jamboree provides an opportunity for interns and senior scientists alike to learn more about the science happening in other disciplines in one room.

NASA's Most Technically Complex Space Observatory Requires Precision

The James Webb Space Telescope is of one the most ambitious and technically complex missions NASA has ever set its focus upon.

Technicians Lay NASA's Webb Sunshield Layers Flat for Inspection

Technicians and engineers working to ensure the soundness of NASA's James Webb Space Telescope manually lower its folded sunshield layers for easier access and inspection

Technicians Ensure James Webb Space Telescope’s Sunshield Survives Stresses Experienced During Liftoff

Acoustic testing exposes the spacecraft to similar forces and stress experienced during liftoff, allowing engineers to better prepare it for the rigors of spaceflight.

NASA’s Webb Space Telescope to Inspect Atmospheres of Gas Giant Exoplanets

One of the most powerful tools that will examine the atmospheres of some planets that TESS discovers will be NASA’s James Webb Space Telescope.

NASA Completes Webb Telescope Review, Commits to Launch in Early 2021

The Independent Review Board (IRB) established by NASA to assess progress on its James Webb Space Telescope has unanimously recommended that development on the world’s premier science observatory should continue; NASA has established a new launch date for Webb of March 30, 2021.

NASA’s James Webb Space Telescope to Target Jupiter’s Great Red Spot

NASA’s James Webb Space Telescope, the most ambitious and complex space observatory ever built, will use its unparalleled infrared capabilities to study Jupiter’s Great Red Spot, shedding new light on the enigmatic storm and building upon data returned from NASA’s Hubble Space Telescope and other observatories.

Engineers Solve Excessive Heat Removal from NASA’s Webb Telescope

To keep heat away from the sensitive instruments, a majority of the electronics used to power and operate the instruments are housed in a compartment below ISIM, where specially designed baffles direct the heat safely into space and away from any cold surfaces of the observatory.

Hubble’s Galaxy Cluster Cornucopia

The swirling spiral to the lower left of the frame is far from the most interesting spectacle here — behind it sits a galaxy cluster.

NASA’s Webb Observatory Spacecraft Element Environmental Testing Update

The spacecraft element of NASA’s James Webb Space Telescope recently completed its first two major launch environmental tests at Northrop Grumman Aerospace Systems in Redondo Beach, California, and will soon undergo further tests to ensure it will handle the rigors of launch and the harsh environment of space.

NASA’s James Webb Space Telescope Could Potentially Detect the First Stars and Black Holes

The first stars in the universe blazed to life about 200 to 400 million years after the big bang.

2020 Decadal Survey Missions: At a Glance

Any telescope that reaches the launch pad in the 2030s likely will look much different than the concepts four teams are currently studying to inform the 2020 Decadal Survey for Astrophysics, but the studies do offer a roadmap.

NASA Teams Study the Agency’s Future in Astrophysics; Tackle Formidable Technology Challenges

As in past decades, the agency won’t make that decision in a vacuum or without understanding the technical obstacles, which are formidable.

NASA Planet Hunter on Its Way to Orbit

NASA’s Transiting Exoplanet Survey Satellite (TESS) has launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life.

New Exoplanet Collaboration Hosts Meeting to Explore Molecular Seeds of Life

The Sellers Exoplanet Environments Collaboration (SEEC) hosts its first annual symposium April 9-13. Researchers will discuss how our knowledge of the early solar system can help the hunt for life on other worlds.

Hubble's Curious Case of a Calcium-rich Supernovae

NGC 5714 is a spiral galaxy, but that feature is hard to see, as NGC 1787 presents itself at an almost perfectly edge-on angle.

NASA Prepares to Launch Next Mission to Search Sky for New Worlds

NASA's Transiting Exoplanet Survey Satellite (TESS) is undergoing final preparations in Florida for its April 16 launch to find undiscovered worlds around nearby stars, providing targets where future studies will assess their capacity to harbor life.

Dark Matter Goes Missing in Oddball Galaxy

Galaxies and dark matter go together like peanut butter and jelly. You typically don't find one without the other.

NASA’s Webb Observatory Requires More Time for Testing and Evaluation; New Launch Window Under Review

NASA’s James Webb Space Telescope currently is undergoing final integration and test phases that will require more time to ensure a successful mission. After an independent assessment of remaining tasks for the highly complex space observatory, Webb’s previously revised 2019 launch window now is targeted for approximately May 2020.
