The Glovebox

The capsule held 0.41 grams of Mars in a titanium sleeve, and under the mission’s own planetary protection plan it could not be opened until the spore on its heat shield was identified. Nandita Reddy had identified it. Bacillus safensis. The cleanroom bug. First described from a spacecraft assembly facility in Florida, which meant, in her opinion, the alien was the building.

She said this to her father on the phone from Mysuru that night. He laughed, short and wet, as he always did, and said, “So it was the west wall.” She had not told him about the west wall. She told him she’d call back. She didn’t.

Nandita had been certifying other people’s hardware for nine years. She had signed off on thrusters and spectrometers and a solar sail that had since left the solar system, and she had never touched a sample. The capsule was the first sample she had been allowed to touch. It sat in a glovebox in Building 7, in a cleanroom in a facility certified sterile in 2019 by a man who was now her father.

The transfer to Pune depended on a paper. The paper depended on the capsule. The capsule depended on the inventory.

She went to work.

The first quarterly review was chaired by a man named Suresh Pillai, who had never been inside a cleanroom and who said, at every meeting, that the capsule was not the sample. He said it the first time with his hands folded on the table, looking at the inventory printout as if it were a menu he could not read. “The capsule is not the sample,” he said. “The sample is what is inside the capsule. The capsule is packaging.”

“The capsule is packaging that has been to Mars,” Nandita said.

“The capsule is packaging,” Suresh said. “What grows on the packaging is a contamination event. We log it and we clean it.”

“We have cleaned it. Three times. Each time a different organism grew.”

“Then we clean it again.”

“Each cleaning attempt grows a different organism. Each organism must be entered in the returned biological inventory. Each entry restarts the quarterly review.”

Suresh looked at her. “That is the process, Nandita.”

“Yes,” she said. “That is the process.”

The first cleaning attempt grew Bacillus safensis, which she had already identified. The second grew Micrococcus luteus, common on human skin, which she entered in the inventory with the note “likely introduced during gowning.” The third grew something she had not seen before, a pink film on the inner seal of the titanium sleeve, and she sent it to the lab in Hyderabad and waited eleven days for a result that came back as Sphingomonas paucimobilis, a waterborne organism that had no business being in a cleanroom at all.

She entered it. The quarterly review restarted.

Arjun Varma, the founder, wanted the glovebox irradiated. He wanted it irradiated because his livestream was scheduled for the fourteenth, and the slogan was First Touch of Another World, and he had already sold the sponsorship. Nandita kept correcting him. “First Touch of Our Own Cleanroom,” she said, in the meeting, in the hallway, and once in the parking lot when he was getting into his car.

He laughed. “Nandini, nobody is going to watch a livestream called First Touch of Our Own Cleanroom.”

“Nandita,” she said. “And they should. That is the actual story.”

“The actual story is that we went to Mars and brought something back.”

“We brought back 0.41 grams of rock. The thing on the heat shield is from this building.”

“Then clean the building.”

“I am cleaning the building. The building keeps growing things.”

The gowning ceremony was scheduled for the livestream crew on the thirteenth, the day before the broadcast. It was a forty-five-minute process: booties, coveralls, gloves, hood, goggles, the slow walk through the airlock, the hands under the UV lamp. Nandita ran it herself because there was no one else. The crew of four stood in a row in the anteroom and complained in whispers that they could hear through the intercom. One of them asked if the gloves came in a smaller size. One of them asked if they could use the bathroom. One of them took a photograph with his phone before Nandita made him put it in a bag.

“Forty-five minutes,” the photographer said. “For a two-minute segment.”

“For a two-minute segment that involves a sample returned from Mars under COSPAR Category V restricted Earth return protocols,” Nandita said. “Yes.”

“What’s COSPAR?”

“It is the committee that decides whether you get to open the canister. The answer is no, until the canister is clean. The canister is not clean.”

“Because of a bug?”

“Because of a bug that was born in this building.”

The photographer looked at the glovebox through the window. “So the alien is the building.”

“That is what I have been saying.”

After the gowning ceremony, Nandita swabbed the founder’s palm. She had not planned it. She was walking past his office on the way to the cleanroom, and he was at his desk with his phone, and she had a swab kit in her hand because she had been swabbing the airlock handle, and she asked him to hold out his hand and he did, without asking why, because he was Arjun Varma and people held out their hands when he asked.

The result came back in three days. Staphylococcus epidermidis, which was on every human hand on earth, and which meant nothing except that Arjun Varma had a hand. But it also came back with a secondary identification: a trace of Bacillus safensis, the same strain from the heat shield, which meant that Arjun Varma had been in the cleanroom, which meant that Arjun Varma had been in the cleanroom without gowning, which meant that the cleanroom had been compromised by the founder himself, possibly more than once.

She entered it in the inventory. The quarterly review restarted.

Suresh Pillai folded his hands. “The capsule is not the sample.”

“The capsule is contaminated by the founder’s ungowned hand, which is a contamination event under the same protocol.”

“The founder is not the sample.”

“The founder is a vector. The vector introduced the organism. The organism is now in the inventory.”

Suresh looked at the printout. “This is the fourth entry.”

“Yes.”

“In one quarter.”

“Yes.”

“We cannot keep restarting the review.”

“Then stop restarting the review and open the capsule.”

“The capsule is not the sample.”

Nandita called her father. She did not ask him about the west wall. She asked him about the certification in 2019. He said it had been a routine audit. He said the panels had passed. He said he had signed the form and driven home to Mysuru and had not thought about it since.

“Did you swab the west wall?” she asked.

“I swabbed the west wall. The swab came back clean.”

“Did you swab behind the panels?”

“There is nothing behind the panels. The panels are the wall.”

“The panels are mounted on a frame. Behind the frame there is a gap. The gap is where the biofilm lives.”

Her father was quiet for a moment. “I did not swab behind the frame. The frame was not in the protocol.”

“Whose protocol?”

“The facility’s protocol. The one they gave me.”

“Who wrote the protocol?”

“I do not remember. Someone in facilities.”

“Did you ask to see behind the panels?”

“No. The panels were certified. The wall behind the panels was not my concern.”

Nandita hung up and sat in her kitchen and looked at the wall, which was a wall, and which had nothing behind it except more wall, and which she had never thought about until now.

The west wall of Building 7 was identified on a Tuesday by a technician named Dev, who had been hired the week before and who had no idea what he was looking at. He was running a routine swab of the cleanroom perimeter and he found a pink film on the seal between the third and fourth panels, and he brought the swab to Nandita, and she recognized the color. Sphingomonas paucimobilis. The waterborne organism. The one that had no business being in a cleanroom.

She asked Dev to pull the panel. He pulled it. Behind the frame, in the gap between the wall and the panel, there was a biofilm the color of old rust, wet, growing slowly in a place no one looked.

She called her father. He was on speaker. She held the phone toward the gap and said, “This is behind the west wall of Building 7. You certified this wall in 2019.”

“I certified the panels,” he said. “The panels are clean.”

“The panels are clean. The wall behind the panels is not. The wall behind the panels has been growing Sphingomonas for at least six years, and the Sphingomonas is in the inventory, and the inventory is in the review, and the review is chaired by a man who has never been in a cleanroom.”

Her father was quiet.

“Was it carelessness or complicity?” she asked.

“Complicity in what? I swabbed the panels. The panels were clean.”

“You signed a form that said the wall was sterile. The wall was not sterile. The form is in the file. The file is in the audit.”

“The form said the panels were sterile. The panels were sterile.”

“The form said the facility was sterile. The facility was not sterile.”

Her father sighed. “Nandita. I am an old man. I swabbed what they told me to swab. I signed what they told me to sign. If they wanted me to look behind the panels, they should have told me to look behind the panels.”

“They did not tell you because they did not want to know.”

“Then they were complicit. I was not. I was careless, at worst. I was a man with a swab and a form.”

Nandita looked at the biofilm. It was the color of old rust, and it was wet, and it had been there for years, and it was the source of everything that had grown in the cleanroom, and it was the source of the pink film on the capsule, and it was the source of the quarterly review, and it was the source of the inventory, and it was the source of her father’s name on a form in a file in an audit.

The livestream was on the fourteenth. Arjun stood in the anteroom in a gown he had put on in twelve minutes, which was a record, and he smiled at the camera and said, “Today we touch another world.” Nandita stood beside him in her gown, which had taken her eight minutes, and she did not smile, and she said, “Today we touch our own cleanroom.”

The camera crew was behind glass. Dev was at the balance. Suresh Pillai was on a video feed from his office, his hands folded, watching.

Nandita opened the glovebox. She opened the titanium sleeve. She lifted the capsule out with tweezers, and she placed it on the balance, and the balance read 0.41 grams.

She looked at the camera. “The capsule is clean,” she said. “The sample inside is 0.41 grams of Martian regolith. The organism on the heat shield is Bacillus safensis, a cleanroom organism first described from a spacecraft assembly facility in Florida. It was not on Mars. It was on the west wall of this building, behind a panel that was certified sterile in 2019 by my father, who swabbed the panel and not the wall behind it, because the protocol did not ask him to.”

She paused. “The protocol did not ask him to because the protocol was written by people who did not want to know.”

On the speaker from Mysuru, her father laughed. Short and wet, as he always did. “So it was the west wall,” he said.

The balance read 0.41 grams. The camera was still running. Dev looked at Nandita. She looked at the balance.
