In this excerpt from “Pillars of Creation: How the James Webb Telescope Unlocked the Secrets of the Cosmos” (Little, Brown Book Group, 2024), author Richard Panek takes a look at the jaw-dropping story behind the launch of the JWST– and how it nearly fell at the last obstacle.

In November 2011, Congress provided its decision on the fate of Webb. Yes, they would continue to money it, however they would do so with a caution, an inviolable spending plan cap:

8 billion dollars or bust.

“If they’re going to cancel, that’s fine,” Mike Menzel would inform his team over the coming years. “Don’t worry. Don’t even listen.”

On a relatively routine basis, Menzel would need to appear before an evaluation board– workouts that his long time Hubble telescope confrère and Webb partner Peter Stockman as soon as compared to Kabuki theater– to discuss why the job was taking so long or costing a lot. His response was practically what he stated when Frank Martin initially revealed him the prepare for the observatory at Lockheed Martin back in the late 1990s:

Counting on analysis– finishing a mathematical design for the part of the satellite on one side of the sunshield, then finishing another mathematical design for the part on the other side of the sunshield, and after that seeing if the designs may match– consisted of a higher capability for human mistake than putting the entire set and caboodle in a numerous-story-high chamber and shaking it as if there were no tomorrow (which, in case of tension- test failures, there may not remain in regards to the objective’s future).

What he required, Menzel would inform the evaluation boards, was “margin”– shorthand not simply for margin of mistake however for margin of mistake beyond the margin of mistake. “The normal rules don’t apply here,” Menzel liked to state. “This is virgin territory” — a landscape of foreseeable difficulties however, more vital for his functions, likewise unforeseeable risks. “Unknown unknowns,” as the Webb team pertained to call the issues they could not envision.

“How much margin do you need?” one program supervisor or another would regularly ask Menzel.

“As much as I can get,” he ‘d address.

Budget plan overruns, administrative impropriety, congressional oversight, evaluation-board numerations, the entire procedure of reconsidering how to check an area telescope from the ground up: Webb had actually endured them all. Another aspect, nevertheless, continued to produce havoc with the budget plan and the launch timeline deep into the 2010s– what Menzel called “stupid mistakes.”

One such error was miswirings that had actually fried a few of the models’ electrical parts– for example, the pressure transducer for the propellant (the transducer being, basically, the gas gauge). Do we fly without pressure transducers? Menzel’s group needed to discuss the concern. The decision: NoThey had to change them.

Another foolish error: the application of an unsuitable solvent that harmed the observatory’s propulsion valves.

And another: 7 tears in the sunshield.

Another: a vibration test for the sunshield that ended with lots of bolts blowing loose and bouncing around the test chamber. The issue ended up being that the bolts had too couple of threads. (Team members were fishing bolts out of far crannies of the center for months later.)

Partially due to the fact that of these mishaps, the launch date slipped from October 2018 to June 2019. The U.S. Government Accountability Office, after performing an examination into the hold-up, launched an analysis warning that even a launch date in June 2019 was likely too positive, and undoubtedly a month after the Accountability Office had actually provided that analysis, NASA revealed an additional hold-up, to spring 2020. It likewise acknowledged that Webb had actually reached Congress’s $8‑billion‑or‑bust spending plan cap … and would require to surpass it, if the telescope was ever to get off the ground.

In January 2019 Congress authorized an additional infusion of $800 million, bringing the overall expenses to$8.8 billion. An accompanying report was harsh. “There is profound disappointment with both NASA and its contractors regarding mismanagement, complete lack of careful oversight, and overall poor basic workmanship on JWST,” the report stated. “NASA and its commercial partners seem to believe that congressional funding for this project and other development efforts is an entitlement, unaffected by failures to stay on schedule or within budget.” And as soon as again Congress threatened the presence of the task: “NASA should strictly adhere to this cap or, under this agreement, JWST will have to find cost savings or cancel the mission.”

“Just forget about them,” Menzel would inform his group. “I don’t care what they say. If you see a problem, just say so, and if we’ve got to delay, we’ll delay.” He compared the last preparations for launch to the folding of a parachute: “One little mistake and we’re dead meat.”

Came Covid, and with it a work downturn, triggering the statement, in July 2020, that the telescope would release no quicker than October 31, 2021.

For 2 years the parts of Webb had actually been coming together at NASA’s Jet Propulsion Laboratory, simply outside Pasadena. Now the time for the telescope to start its journey from Long Beach to the launchpad at the European spaceport off the northeast coast of South America, near Kourou, French Guiana. The spin of the Earth assists include momentum to a rocket launch, which spin is biggest at the equator; Kourou is just 3 hundred approximately miles north of it. The telescope could not be delivered as if it were just one more piece of freight aboard a truck. It needed an unique temperature level- and humidity-regulated container. (The freight itself had the opposite requirement: It required to be as non‑special, as confidential, as possible, so regarding defend against the possibility, nevertheless remote, that pirates may take the ship and hold its $8.8 billion freight captive.)

The observatory made it through the sixteen-day, 5,800-mile passage down the west coast of Mexico, through the Panama Canal, up the Kourou River to the Port de Pariacabo, and into a processing center near the launch website in French Guiana without occurrence– however then it suffered a shock. A high stress clamp band snapped off, shaking the observatory. An assessment exposed no damage, however the late-December launch slipped another couple of days.

Even the name of the telescope, in those last weeks, ended up being an interruption, albeit of the general public-relations kind. The period of the historic personage of James Webb as the 2nd in command at the Department of State in the late 1940s and early 1950s and after that as the head of NASA in the 1960s accompanied what historians have actually concerned call the “lavender scare” — a look for and purge of LGBTQ staff members at federal organizations (seemingly due to the fact that they may be based on blackmail and for that reason posture a security threat). Examinations had actually shown up little particular proof of James Webb’s participation, however the association in between administration and bigotry was close enough that some astronomers chose they would compromise linguistic benefit and afterwards describe the telescope not as “Webb,” a one-syllable nibble, however just as “JWST,” a 6-syllable Dagwood sandwich.

Regardless of the objective’s history of nonlinearity over the previous years, it could not have actually reached this last phase without a lot going. You might miss out on that viewpoint if you remained in the eye of the maelstrom and even carefully observing it. Nevertheless, nobody associated with the task might understand how much had actually gone right up until the Ariane 5 rocket bearing Webb had actually not simply taken off however made it through “six months of terror” (as the media liked to state). Throughout those months the observatory would face 344 “single points of failure,” in NASA nomenclature– executions of innovation that would expose whether the wonders of development and resourcefulness that were distinct to this objective in fact worked on‑site (that is to state, in area), the failure of any among which would scuttle the whole job.

Those very first 6 months, however, weren’t what the researchers at the Institute and NASA were most worried about. It was, rather, the very first thirty days. Or perhaps even the very first 2 weeks, the duration throughout which Webb would perform a few of its most complex workouts.

With a projection of high winds for December 24, 2021, the launch slipped one last time. On the early morning of December 25, in the 2nd-story command center at the Institute, in the auditorium downstairs on the primary flooring, at seeing celebrations at aerospace centers all over the world, and in front of computer system screens on every continent, people collected to view and wait.

At 7:20 a.m. Baltimore time– Baltimore time thenceforth being the main timestamp for the invoice of Webb’s nonterrestrial interactions– the countdown to the launch reached that antique from the 1960s Space Race: the backwards count to blastoff.
