James Webb Space Telescope Launch Souvenir T-Shirt

Product Information

Temperatures are updated once per day daily during Webb's cool down and then weekly through the end of commissiong once they are at operational levels (see blog: Final Temperature? ). In general, temperatures change slowly so this frequency is sufficient to give a snapshot of overall trends. Temperatures are rounded to the nearest whole number and displayed in the users choice of Farenheit or Celsius along with Kelvin in parentheses.

Zoom In/Out : Use the + or - buttons in upper right to zoom the plot over all. Use the magnifying glass to select a specfic part of the plot and zoom in. Use the "home" button to reset the plot to original state. Webb is the premier observatory of the next decade, serving thousands of astronomers worldwide. It studies every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System. The James Webb Space Telescope (sometimes called JWST or Webb) is an orbiting infrared observatory that willNumerous scientists involved with the Nexus for Exoplanet System Science ( NExSS) have been and continue to be a part of the Webb mission. NExSS is a NASA Research Coordination Network ( RCN) dedicated to studying planetary habitability. Data from Webb is important in investigating the diversity of exoplanets and to learning how their history, geology, and climate interact to create the conditions for life.

The James Webb Space Telescope (Webb) is the premier space-based observatory of the next decade. Webb is a large infrared telescope with a 6.5-meter primary mirror. It will serve thousands of astronomers worldwide.You can EXPLORE past and upcoming deployments on the way to L2 and through commissioning. The Deployment Explorer opens to the most recently completed (unless noted as "Status:Ongoing" ) deployment/commissioning step, all steps to the "left" (on the top thumbnail nav) are COMPLETED, all steps to the "right" (on the top thumbnail nav) are FUTURE. Zoom In/Out : Desktop- mouse wheel, Mobile/Touch- pinch in/out. Keyboard: ZOOM in/out - W/S, Add SHIFT for faster speed. What you see now is the final state of Webb as it entered 'Ongoing Science Operations Mode'. The temperatures displayed show that they have reached and are maintained at a narrow band steady state. You can explore the entire annotated deployment and commissioning process on the Webb Deployment Explorer. Data Values: data values can be seen for each point plotted by hovering over the traces (tap on touch devices), the trace name and values are displayed in a pop up message. Locating the Observation Points : this button will open a panel to identify the locations of the temperature observation points on the spacecraft.

Then, turn off the artificial fill lights (lower right light bulb icon) and you will understand one of the key reasons why cameras for monitoring would not be helpful on Webb. It's completely in the dark on the mirror side of the sunshield. Compare Webb's size to other objects like a school bus or Hubble: Use the 'Compare' link at bottom of the title/ID panel to cycle through a list of objects. With much higher speeds early in the trip, Webb covers a large percentage of the distance to L2 orbit early in its trip. This can be seen by toggling the "time" vs "distance %" views on the "progress line". Webb's speed is at its peak while connected to the push of the launch vehicle. It begins to slow rapidly after separation as it coasts up hill climbing the gravity ridge from Earth to its orbit around L2. Note on the TIME view that Webb reaches the altitude of the moon in ~2.5 days (which is ~8% of the total trip time but ~25% of its trip distance). See the sections below on Distance to L2 and Arrival at L2 for more information on the distance travelled to L2. The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with an approximately 6.5 meter primary mirror. Webb successfully launched from ESA's spaceport in French Guiana on December 25, 2021 07:20am EST ( 2021-12-25 12:20 GMT/UTC) .
