I bought “Remove Before Flight” tags on eBay in 2010—it turns out they’re from Challenger


40th anniversary of the Challenger tragedy

Forty years ago, a stack of bright red tags shared a physical connection with what would become NASA’s first space shuttle disaster. The small tags, however, were collected before the ill-fated launch of Challenger, as was instructed in bold “Remove Before Flight” lettering on the front of each.

What happened to the tags after that is largely unknown.

This is an attempt to learn more about where those “Remove Before Flight” tags went after they were detached from the space shuttle and before they arrived on my doorstep. If their history can be better documented, they can be provided to museums, educational centers, and astronautical archives for their preservation and display.

To begin, we go back 16 years to when they were offered for sale on eBay.

From handout to hold on

The advertisement on the auction website was titled “Space Shuttle Remove Before Flight Flags Lot of 18.” They were listed with an opening bid of $3.99. On January 12, 2010, I paid $5.50 as the winner.

At that point, my interest in the 3-inch-wide by 12-inch-long (7.6 by 30.5 cm) tags was as handouts for kids and other attendees at future events. Whether it was at an astronaut autograph convention, a space memorabilia show, a classroom visit, or a conference talk, having “swag” was a great way to foster interest in space history. At first glance, these flags seemed to be a perfect fit.

So I didn’t pay much attention when they first arrived. The eBay listing had promoted them only as generic examples of “KSC Form 4-226 (6/77)”—the ID the Kennedy Space Center assigned to the tags. There was no mention of their being used, let alone specifying an orbiter or specific flight. If I recall correctly, the seller said his intention had been to use them on his boat.

(Attempts to retrieve the original listing for this article were unsuccessful. As an eBay spokesperson said, “eBay does not retain transaction records or item details dating back over a decade, and therefore we do not have any information to share with you.”)

It was about a year later when I first noticed the ink stamps at the bottom of each tag. They were marked “ET-26” followed by a number. For example, the first tag in the clipped-together stack was stamped “ET-26-000006.”

Bright red tags can be seen attached to a large component of space shuttle hardware.

The same type of “Remove Before Flight” tags that were attached to ET-26 for Challenger‘s ill-fated STS-51L mission can be seen on one of the first two external tanks before it was flown, as distinguished by the insulation having been painted white.

“ET” refers to the External Tank. The largest components of the space shuttle stack, the burnt orange or brown tanks were numbered, so 26 had to be one of the earlier missions of the 30-year, 135-flight program.

A fact sheet prepared by Lockheed Martin provided the answer. The company operated at the Michoud Assembly Facility near New Orleans, where the external tanks were built before being barged to the Kennedy Space Center for launch. Part of the sheet listed each launch with its date and numbered external tank. As my finger traced down the page, it came to STS 61-B, 11/26/85, ET-22; STS 61-C, 1/12/86, ET-30; and then STS 51-L, 1/28/86… ET-26.

Removed but still connected

To be clear, the tags had no role in the loss of Challenger or its crew, including commander Dick Scobee; pilot Mike Smith; mission specialists Ronald McNair, Judith Resnik, and Ellison Onizuka; payload specialist Gregory Jarvis; and Teacher-in-Space Christa McAuliffe. Although the structural failure of the external tank ultimately resulted in Challenger breaking apart, it was a compromised O-ring seal in one of the shuttle’s two solid rocket boosters that allowed hot gas to burn through, impinging the tank.

Further, although it’s still unknown when the tags and their associated ground support equipment (e.g., protective covers, caps) were removed, it was not within hours of the launch, and in many cases, it was completed well before the vehicle reached the pad.

“They were removed later in processing at different times but definitely all done before propellant loading,” said Mike Cianilli, the former manager of NASA’s Apollo, Challenger, Columbia Lessons Learned Program. “To make sure they were gone, final walkdowns and closeouts by the ground crews confirmed removal.”

This was the first visible sign that an SRB joint breach may have occurred, leading to the external tank (ET-26) being compromised during its ascent.

According to NASA, approximately 20 percent of ET-26 was recovered from the ocean floor after the tragedy, and like the parts of the solid rocket boosters and Challenger, they were placed into storage in two retired missile silos at the Cape Canaveral Air Force Station (today, Space Force Station). Components removed from the vehicle before the ill-fated launch that were no longer needed likely went through the normal surplus processes as overseen by the General Services Administration, said Cianilli.

Once the tags’ association with STS-51L was confirmed, it no longer felt right to use them as giveaways. At least, not to individuals.

There are very few items directly connected to Challenger‘s last flight that museums and other public centers can use to connect their visitors to what transpired 40 years ago. NASA has placed only one piece of Challenger on public display, and that is in the exhibition “Forever Remembered” at the Kennedy Space Center Visitor Complex.

Each of the 50 US states, the Smithsonian, and the president of the United States were also presented with a small American flag and a mission patch that had been aboard Challenger at the time of the tragedy.

Having a more complete history of these tags would help meet the accession requirements of some museums and, if approved, provide curators with the information they need to put the tags on display.

Reconnecting to flight

When the tags were first identified, contacts at NASA and Lockheed, among others, were unable to explain how they ended up on eBay and, ultimately, with me.

It was 2011, and the space shuttle program was coming to its end. I was politely told that this was not the time to ask about the tags, as documents were being moved into archives and, perhaps more importantly, people were more concerned about pending layoffs. One person suggested the tags be put back in a drawer and forgotten about for another decade.

In the years since, other “Remove Before Flight” tags from other space shuttle missions have come up for sale. Some have included evidence that the tags had passed through the surplus procedures; some did not and were offered as is.

There were anecdotes about outgoing employees taking home mementos. Maybe someone saw these tags heading out as scrap (or worse, being tossed in the garbage) and, recognizing what they were, saved them from being lost to history. An agent with the NASA Office of Inspector General once said that dumpster diving was not prohibited, so long as the item(s) being dived for were not metal (due to recycling).

More recent attempts to reach people who might know anything about the specific tags have been unsuccessful, other than the few details Cianilli was able to share. An attempt to recontact the eBay seller has so far gone unanswered.

If you or someone you know worked on the external tank at the time of the STS-51L tragedy, or if you’re familiar with NASA’s practices regarding installing, retrieving, and archiving or disposing of the Remove Before Flight tags, please get in contact.

Artemis IV will mark the second lunar landing of the Artemis program and build upon what is learned at the moon’s south pole on Artemis III.

“After his voyage to the Moon’s surface during Apollo 17, astronaut Gene Cernan acknowledged the challenge that lunar dust presents to long-term lunar exploration. Moon dust sticks to everything it touches and is very abrasive,” read NASA’s announcement of the Artemis IV science payloads.

To that end, the solar-powered MAPP will support DUSTER (DUst and plaSma environmenT survEyoR), a two-part investigation from the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado, Boulder. The autonomous rover’s equipment will include the Electrostatic Dust Analyzer (EDA), which will measure the charge, velocity, size, and flux of dust particles lofted from the lunar surface, and the RElaxation SOunder and differentiaL VoltagE (RESOLVE) instrument, which will characterize the average electron density above the lunar surface using plasma sounding.

The University of Central Florida and University of California, Berkeley, have joined with LASP to interpret measurements taken by DUSTER. The former will look at the dust ejecta generated during the Human Landing System (HLS, or lunar lander) liftoff from the Moon, while the latter will analyze upstream plasma conditions.

Lunar dust attaches to almost everything it comes into contact with, posing a risk to equipment and spacesuits. It can also obstruct solar panels, reducing their ability to generate electricity and cause thermal radiators to overheat. The dust can also endanger astronauts’ health if inhaled.

“We need to develop a complete picture of the dust and plasma environment at the lunar south pole and how it varies over time and location to ensure astronaut safety and the operation of exploration equipment,” said Xu Wang, senior researcher at LASP and principal investigator of DUSTER, in a University of Colorado statement. “By studying this environment, we gain crucial insights that will guide mitigation strategies and methods to enable long-term, sustained human exploration on the Moon.”

Lego announces NASA Artemis SLS rocket set to lift off (literally) in 2026

How do you top a highly detailed scale model of NASA’s new moon-bound rocket and its support tower? If you’re Lego, you make it so it can actually lift off.

Lego’s NASA Artemis Space Launch System Rocket, part of its Technic line of advanced building sets, will land on store shelves for $60 on January 1, 2026, and then “blast off” from kitchen tables, office desks and living room floors. The 632-piece set climbs skyward, separating from its expendable stages along the way, until the Orion crew spacecraft and its European Service Module top out the motion on their way to the moon—or wherever your imagination carries it.

“The educational LEGO Technic set shows the moment a rocket launches, in three distinct stages,” reads the product description on Lego’s website. “Turn the crank to see the solid rocket boosters separate from the core stage, which then also detaches. Continue turning to watch the upper stage with its engine module, Orion spacecraft and launch abort system separate.”

Crank it up

The new set captures all the major milestones of the first eight and a half minutes of an Artemis mission (with the exception of the jettison of the abort system tower, which on the real rocket occurs before the Orion separates from the core stage). Lego worked with NASA and the European Space Agency (ESA) to ensure the overall accuracy of the display.

“On the way up, there is sound. You can hear it—it is really noisy, the rocket,” said Olaf Kegger, the set’s designer at Lego, at an unveiling of his creation. He added that there is no sound when the motion is reversed, as the real SLS, “of course, does not go [back] down like this.”

The set’s large, main futuristic rover with its rocker suspension, four-wheel steering, deployable solar panels, and rotating arm is not based on any specific vehicle Lunar Outpost is building now, but was inspired by the company’s plans.

More to come

“We have five lunar surface missions in total booked. One of the upcoming ones is really cool. It’s with the Australian Space Agency, so it will be Australia’s flagship lunar rover, which they affectionately call ‘Roo-ver,’ which I just love,” said Gemer.

Lunar Outpost’s next MAPP is targeted for launch in spring 2026. Using science instruments developed by NASA and the Johns Hopkins University Applied Physics Laboratory (JHU APL), the rover will investigate a magnetic anomaly that has gone unexplained for hundreds of years.

“So those missions will be going, [but] we want to do bigger things, better things, more collaborative, robotic missions. We really want to be the foundational infrastructure on the Moon,” Gemer said. “Mobility is one of those key enablers to building big and exciting things like a permanent human presence on the moon. So that’s why we set out to be the leaders in space mobility, and I think that’s what we’ve accomplished.”

Similarly, Lego is a leader when it comes to inspiring the next generation as to what is possible.

“I bet most engineers started out as a kid playing with Lego,” said Gemer. “We’ve got lots of great work to do with Lego, because it’s one of those foundational, inspirational things for kids in STEM [science, technology, engineering, and math]. Tying that to space exploration, which is another one of those things everyone can connect with, it’s just a really natural partnership.”

Which brings it all back to Ari and Aiden and the Moon Rover Space Vehicle set.

“We built the MAPP rover, and then the resource collection rover. We are working our way up to the big one,” said Gemer. “I just want them to enjoy building it.”

‘Not that into peace doves’: The Apollo-Soyuz patch NASA rejected

Rejects and revivals

Calle’s patch design was not the only one ruled out by NASA’s officials.

At first, Stafford, Brand, and Slayton chose a design from a contest among the US space program’s workforce. The winner, Jean Pinataro of North American Rockwell (the prime contractor for the Apollo command module), came up with a concept that the astronauts liked, but the agency’s leaders rejected it for not having enough “international significance” (unofficially, it was also said to be “cartoonish”).

That led to NASA accepting the cost of hiring an artist from the NASA art program and Calle being invited to offer his ideas. It also resulted in the patch that flew.

When Calle stepped away, the decision was made to repurpose the work of Bob McCall, an artist who had designed the Apollo 17 mission patch and in 1974 had painted the scene of the Apollo and Soyuz spacecraft nearing a docking. McCall would go on to create similar art for a pair of postage stamps issued in the United States and the Soviet Union, while Pinataro adapted McCall’s original painting as the central image of the US ASTP emblem.

The cosmonauts had their own design—in fact, it was the first Russian mission patch to involve the crew’s input—but wore both their own and the US patch during their six days in space.

Today, 50 years later, the McCall-inspired design, the cosmonauts’ patch, and the Apollo-Soyuz program insignia are used interchangeably to represent the mission. Calle’s designs have been largely forgotten but are now getting a revival for the golden anniversary.

“I wanted to reimagine them. Not redo them, but bring them to life,” said Chris.

Working with a fellow artist Tim Gagnon, who created a number of the mission patches worn by space shuttle and International Space Station crews, Chris has begun the process of producing a limited number of embroidered patches based on his and his late father’s ideas.

Chris primarily focused on Calle’s dove and olive branch design.

“It certainly keeps to the spirit of my dad’s original idea,” Chris said.

Chris Calle asks readers to contact him via his website to be informed about when the limited-edition Apollo-Soyuz patches are available.
