Announced by the USPS on May 3^rd:

Celebrate NASA’s remarkable James Webb Space Telescope, the largest and most complex telescope ever deployed in space—capable of peering directly into the early cosmos and studying every phase of cosmic history. Launched on Dec. 25, 2021, Webb now orbits the Sun about a million miles away from Earth.

The image on the stamp is an artist’s digitally created depiction of the telescope against a dazzling starscape. The selvage photograph of a star and distant space was taken by Webb early in its mission, brilliantly confirming the perfect alignment of the telescope’s 18 mirror segments.

Art director Derry Noyes designed the stamp using existing art by James Vaughan and an image provided by NASA/Space Telescope Science Institute.

Additional information will be posted below the line, with the most recent info near the top.

USPS Celebrates James Webb Space Telescope

Background: The U.S. Postal Service celebrates NASA’s remarkable James Webb Space Telescope, the largest and most complex telescope ever deployed in space — capable of peering directly into the early cosmos and studying every phase of cosmic history.

Its gold-coated mirror segments form a 21-foot-wide lens that captures faint infrared rays from billions of light-years away that represent the universe’s first accessible starlight. Revealed is the universe in its infancy, including galaxy formation. The Webb Telescope can also analyze exoplanets for potentially life-supporting conditions and provide unprecedentedly high-resolution views of our own solar system.

The heat-sensitive telescope must operate in extreme cold. From its orbit of the sun about a million miles from Earth, it is constantly positioned above the planet’s night side, orienting its optics and instruments in perpetual shade from the sun and Earth behind its tennis-court-size solar shield.

Launched on Christmas Day 2021, the telescope represents multinational cooperation of NASA and the European and Canadian space agencies.

During the telescope’s expected five- to 10-year mission, scientists anticipate answers to age-old questions — plus introductions to new cosmic mysteries.

The image on the stamp is an artist’s digitally created depiction of the telescope against a dazzling starscape. The selvage image of a star and distant space was taken by the telescope early in its mission, brilliantly confirming the perfect alignment of the telescope’s 18 mirror segments.

The James Webb Space Telescope stamp is being issued as a Forever stamp in panes of 20. This Forever stamp is always equal in value to the current First-Class Mail 1-ounce price.

Preorders for the James Webb Space Telescope Forever stamp can be made online at usps.com/stampsbeginning August 8.

Updated June 15^th:
This stamp will be issued September 8th with a Washington, DC postmark.

Updated May 13^th:
The telescope is expected to go into operation in June 2022. Could this stamp be issued then?
