NASA published a retrospective on Oct. 29, 2026, showing how International Space Station crews have celebrated Halloween with costumes. The agency says astronauts sometimes make outfits from materials already aboard the station; the report does not describe a new celebration or identify a specific crew’s plans for this year.

NASA published a retrospective on Oct. 29, 2026, showing how astronauts aboard the International Space Station have marked Halloween with costumes, including outfits sometimes designed from materials available in orbit. The agency’s report looks at celebrations from past crews; it does not announce a specific Halloween event planned for the station this year.

NASA’s Johnson Space Center Office of Communications says station crew members have celebrated Halloween either individually or as an entire crew. Their costumes have ranged from spooky to playful, and astronauts have used supplies already aboard the orbiting laboratory to make some of them. The agency’s report points readers to images of past celebrations rather than describing a single new event.

The report notes that the station has no trick-or-treaters knocking at its front hatch, a reminder that the holiday takes a different form in orbit. It does not say which astronauts appear in the images, when each photograph was taken, or what materials were used for particular costumes. NASA’s item is a brief retrospective, not a schedule or operational update.

Alongside the Halloween images, NASA directs readers to more stories, photographs and research about the station. The agency describes the ISS as a scientific platform supporting human activity in space and notes that it has hosted more than 25 years of continuous human presence. The Halloween report presents the celebrations as one part of life aboard the laboratory.

A Holiday Adapted to Orbit

The images offer a glimpse of the human routines that accompany scientific work on a permanently crewed spacecraft. Celebrating a familiar holiday can provide astronauts a shared activity and a connection to life on Earth, although NASA’s report does not assess the effect of these celebrations on crew morale or performance.

The mention of costumes made from onboard materials also shows how crews can adapt ordinary traditions to the constraints of a space station. In orbit, there is no door-to-door trick-or-treating, and the report gives no account of sweets or other Halloween customs. Instead, its focus is on costumes and crew participation. The retrospective gives readers a small, accessible view of daily life alongside the ISS’s research role.

For readers following the station, the distinction between a retrospective and a current event matters: NASA has shared examples from past years, but it has not confirmed what the present crew will do on Oct. 31. The images illustrate an ongoing tradition, not a newly announced station-wide program.

Past Halloween Photos From the ISS

The NASA item was published by the Johnson Space Center Office of Communications on Oct. 29, two days before Halloween. Its stated purpose is to show how station crews have celebrated in years past and to encourage readers to follow astronauts’ holiday activities in space. The report does not give a year-by-year timeline or name the crew members shown.

NASA links the feature to material about the ISS and its history. The station has supported continuous human presence for more than 25 years, according to the agency. That background helps explain why its archive includes recurring moments from crew life as well as research updates. The Halloween feature is a short selection from that broader record, not a complete history of celebrations aboard the station.

The practical setting shapes the tradition: astronauts live and work inside an orbiting laboratory, and any costumes described as made from available materials must use what is on hand. NASA does not specify the station’s inventory or say whether particular costume components were reused, improvised, or sent from Earth.

This Year’s Crew Plans Are Unconfirmed

NASA’s Oct. 29 report does not confirm whether the crew aboard the ISS will hold a Halloween celebration on Oct. 31, what costumes they might wear, or whether the agency plans to publish new photographs. It also does not identify the dates, astronauts, or specific materials associated with the past images it highlights. The feature is a retrospective, so details beyond the agency’s general description are not established by the source.

NASA’s report does not provide information about any Halloween-related changes to station operations or research schedules. It gives no evidence that the holiday affects the station’s scientific work, and no such effect should be inferred from the images alone.

NASA May Share More Crew Images

NASA encourages readers to follow astronauts aboard the station for holiday coverage and links to its wider collection of ISS stories, images and research. The agency has not announced a date for additional Halloween material or confirmed that new images will be released this year. Any account of the current crew’s plans would depend on a later NASA update or other direct reporting.

For now, the confirmed development is the publication of a short look back at past celebrations. Readers can use NASA’s linked station resources to explore the broader archive, while distinguishing those historical images from any future report about this year’s crew.

Key Questions

What did NASA announce about Halloween on the ISS?

NASA published a retrospective on Oct. 29, 2026, featuring how past station crews have marked Halloween with costumes. It did not announce a new event for this year.

How do astronauts celebrate Halloween in orbit?

NASA says crew members have dressed up individually or together. Some costumes have been designed using materials available aboard the station. The report does not describe every custom crews may observe.

Are trick-or-treaters able to visit the space station?

No. NASA notes that trick-or-treaters do not knock at the station’s hatch. The feature focuses on astronauts’ costumes rather than door-to-door celebrations.

Has NASA confirmed what the current crew will do this Halloween?

No. The report shows past celebrations and does not state whether the current crew will celebrate on Oct. 31 or publish new photos.

Why did NASA publish the Halloween feature?

The agency invited readers to look at past station celebrations and follow astronauts’ holiday activities. It also linked the feature to the ISS’s broader collection of stories, images and research.
