— The space capsules used to deliver crew and cargo to and from the International Space Station are now available for delivery on envelopes and postcards mailed through a Houston post office.
Russia's piloted Soyuz spacecraft and SpaceX's uncrewed Dragon cargo capsule are featured on two new pictorial postmarks now offered by the U.S. Postal Service (USPS). The black and white ink stamps also depict the space station.
The postmarks, which are not date specific, are intended to commemorate future flights and mission milestones for the Soyuz and Dragon. Houston is home to NASA's International Space Station mission control, from where the orbiting lab is managed.
"The Postal Service offers pictorial postmarks to commemorate events celebrated in communities throughout the nation," the USPS describes on its website.
The "ISS Dragon Space Station Postmark" features the cargo capsule nearing the orbital complex. "ISS Mission Control Station" tops the design.
The "ISS Soyuz Houston Postmark" is similar in style, with the Russian spacecraft illustrated in the lower right corner.
Both marks were created by artist Detlev van Ravanswaay of Duisberg, Germany.
It is popular among stamp collectors to have envelopes stamped and postmarked to commemorate the dates of significant or historic events. Referred to as "covers," the postal cancellations serve as a record of when and where the event occurred.
For events that occur in space, it is common for collectors to have their covers postmarked at postal stations located near where the mission was launched or, as in the case of Houston, where it was managed by flight controllers.
NASA's Mission Control Center oversees the station, while flight control centers in California and outside of Moscow direct the Dragon and Soyuz, respectively.
Collectors, space enthusiasts and members of the general public who desire the Dragon or Soyuz postmarks can mail their stamped envelopes or postcards to:
ISS Dragon Space Station Postmark, or
ISS Soyuz Houston Postmark
c/o Station Manager
Sam Houston Station
Attn: Mr. Kenneth Cooper
1500 Hadley Street
Houston, TX 77002-9998
Both postmarks have interchangeable dates, such that requests can be made for any date beginning Aug. 8, 2013 and going forward. Requests must be received in Houston however, within 30 days of the requested date.
The USPS advises on its website that those desiring the use of one of the marks should "affix stamps to any envelope or postcard of their choice, address the envelope or postcard to themselves or others, insert a card of postcard thickness in envelopes for sturdiness, and tuck in the flap."
"Place the envelope or postcard in a larger envelope and address it to [the postal station's address]," the USPS writes.
Collectors can also send stamped envelopes or postcards without address, so "long as they supply a larger envelope with adequate postage and their return address," states the postal service. "After applying the pictorial postmark, the U.S. Postal Service returns the items (with or without addresses) under addressed protective cover."
SpaceX is one of two companies NASA has contracted to deliver supplies to the space station. The company's Dragon capsule is currently the only vehicle capable of returning large amounts of experiment results and hardware to Earth.
SpaceX is slated to launch its next Dragon capsule atop a Falcon 9 rocket from Cape Canaveral, Fla. in December, on what will be the company's third resupply mission to the space station.
Russia's next Soyuz spacecraft is slated to liftoff from the Baikonur Cosmodrome in Kazakhstan on Sept. 25 with three new crew members for the station's 37th expedition. NASA is relying on the Soyuz to fly its astronauts to and from the orbiting outpost until U.S. commercial spacecraft are ready to begin crewed launch services.
