Excerpt from “Growing Peppers on the ISS Is Just the Start of Space Farming”

The author, Melanie Canales, is a first-generation Peruvian American farmer and beekeeper based in Virginia’s Shenandoah Valley, on lands of the indigenous Monacan and Manahoac tribes. Her work focuses on creating healthy relationships between people and their surrounding ecosystems.
Unburdened by the constraints of gravity, red and green peppers jut out at 45-degree angles inside the Advanced Plant Habitat (APH), a sort of space terrarium not much larger than a microwave. Four chile pepper plants stand effortlessly upright, despite the dozens of glossy fruits weighing them down. These plants have lived entirely in space; their leaves have never been chewed on by insects or rustled by a summer breeze, [and] their stems are unfamiliar with bending toward the sun’s arc across the sky. Scissors glint under the tank’s white and blue lights as astronaut Mark Vande Hei and his team snip the stems of those that are ready for harvest. The peppers whirl around their heads until the astronauts catch them and tape them against a board to photograph.
Back on Earth, the Plant Habitat-04 team of engineers and plant scientists are observing and conferring with the astronauts. Of the 26 peppers in this batch, only the 14 finest will stay on the International Space Station [ISS] for consumption. The rest will be wrapped in foil, sealed in a Ziploc bag, then frozen at a brisk −80 degrees, until they can come roaring back to Earth in the next cargo capsule to be studied later. Now, after a 137-day growth cycle, the astronauts remove the plants from the module and trash them. Project Plant Habitat-04 is complete. It’s taco night on the ISS.
Since 2014, NASA1 has experimented with growing lettuces, brassicas,2 and zinnias3 in space, an endeavor that relies on highly specialized technology over 50 years in the making. [Fall 2021’s] two successful pepper harvests . . . will provide data on the nutritional and psychological benefits of growing vegetables on-craft, as well as a crop’s ability to reliably produce long-term in microgravity. While controlled environmental agriculture is not new, the APH experiment represents an evolution in specialized growth habitats. It doesn’t aim to re-create Earth’s conditions, but to perfect each isolated variable of plant growth in the clinical environment of a spaceship.
“The Advanced Plant Habitat is the most complex plant growth system on orbit today,” says Lashelle Spencer, a plant scientist at NASA’s Kennedy Space Center. Its more than 180 sensors control and monitor temperature, humidity, and carbon dioxide. The astronauts can adjust the color and intensity of the light, and how much moisture the plants’ roots are getting. It waters itself.
It’s the day after Thanksgiving, and Spencer has been at Kennedy since 5 a.m. to facilitate the peppers’ final harvest. As part of the project team, she played a crucial role in preparing the seeds that were sent hurtling into space in June and guiding the astronauts through maintaining the plants in orbit. . . . Though astronauts can spend upwards of 100 days in space, their on-mission meals come dehydrated and pre-packaged; their vitamins and minerals are isolated in supplements, which lose nutritional value the longer they’re stored. Spencer’s goal is to create the conditions necessary for cultivating healthy plants in space, so those plants can sustain healthy astronauts on long-term missions. Astronaut food is great, she says—“especially the shrimp cocktail. But you’re missing that crunch. You’re missing that fresh pop of flavor, the green flavor that’s not there in that packaged food.”
The sensory experience of growing productive crops can also help mitigate4 the psychological effects of long-term space travel. . . . Spencer says the team cracked open the door of the APH every day to observe their vegetable companions with all the tenderness of home gardeners. When harvest day came, they batted their bounty around the ISS, taking selfies and delighting in watching the fruits pirouetting around the spacecraft. . . .
“We were thinking no heat, so that [the peppers] wouldn’t be dangerous, but maybe the astronauts need a little spice in their life,” says Paul Bosland, who along with his colleagues at the Chile Pepper Institute genetically engineered5 the NuMex Española Improved chile pepper seeds grown in Plant Habitat-04. . . .
Working with NASA, Bosland cultivated a variety that could accommodate both the nutritional needs of astronauts as well as the logistics of growing a plant in space. . . .
. . . The experiment is helping gather the data necessary to determine the nutritional content of crops grown in space, and therefore how many people they can feed, and for how long. Though much is still unknown, Spencer is certain of one thing that future astronauts will need to do: “I think in an optimal world, a scientist like me would say that they would be growing plants from day one. From the day they left to the day they came back, they would be growing them.”

- E“I think in an optimal world, a scientist like me would say that they would be growing plants from day one.
Show the answer
Correct answer: B and C
The question asks which two sentences in paragraphs 5–9 best support the idea that the astronauts working in space enjoyed participating in the food-growing experiment.
Incorrect. Choice 1. “But you’re missing that crunch. You’re missing that fresh pop of flavor, the green flavor that’s not there in that packaged food” is incorrect because it illustrates an opinion on fresh foods of Lashelle Spencer, a plant scientist at NASA’s Kennedy Space Center. Although astronauts are likely to enjoy fresh food, the statement does not describe the enjoyment of the astronauts participating in the experiment.
CORRECT. Choice 2. “Spencer says the team cracked open the door of the APH every day to observe their vegetable companions with all the tenderness of home gardeners” is a correct response. The details about the attitude of the astronauts toward the plants and their desire to observe them every day support the idea that they enjoyed participating in the experiment.
CORRECT. Choice 3. “When harvest day came, they batted their bounty around the ISS, taking selfies and delighting in watching the fruits pirouetting around the spacecraft” is a correct response. That the astronauts were taking selfies with the peppers and “delighting in watching the fruits pirouetting around the spacecraft” suggests that the astronauts enjoyed being part of the experiment.
Incorrect. Choice 4. “ ‘We were thinking no heat, so that [the peppers] wouldn’t be dangerous, but maybe the astronauts need a little spice in their life,’ says Paul Bosland” is incorrect because the quotation only gives information about the variables taken into account in the selection of peppers by a scientist at the Chile Pepper Institute. Although the observation suggests that the spicy heat of peppers might be enjoyed by astronauts in space, the sentence does not address the attitude of the astronauts toward the experiment.
Incorrect. Choice 5. “ ‘I think in an optimal world, a scientist like me would say that they would be growing plants from day one’ ” is incorrect because it emphasizes the opinion of Lashelle Spencer, a plant scientist at NASA’s Kennedy Space Center, regarding the growth of plants in space. Although she suggests growing plants is a good idea, the quotation does not support the idea that the astronauts enjoyed participating in the experiment.
Question analysis
This select-two evidence question asks which two sentences in paragraphs 5–9 of the space-farming excerpt best show that the astronauts enjoyed taking part in the pepper-growing experiment. On the test students click two of five sentences highlighted in the passage, and credit comes only when both picks are right. Each sentence mentions food, peppers or plants, so each must be checked against the idea itself.

Why it is hard, traps and wrong answers (shows the answer)
Why it is hard
The harvest-day sentence, with its selfies and delight, is the easy pick. The second takes more care, because “the team” that opened the habitat every day seems at first to be Spencer’s team on Earth, and both picks must be right for credit. Students who look for the word “astronauts” or a cheerful phrase are pulled to Bosland’s “a little spice in their life” or to Spencer’s longing for crunch, which report the views of the scientists.
Reading between the lines moderate Working it out
The second right sentence says “the team” opened the habitat’s door, right after paragraph 5 called Spencer “part of the project team,” so students must see that only the crew aboard could do it. (Graesser, Singer & Trabasso, 1994; Kintsch, 1998)
Every choice must be checked minor Choosing the answer
All five sentences mention food, peppers or plants, and credit needs both picks, so each must be traced to its speaker: Spencer, the crew or Bosland. (Embretson & Wetzel, 1987)
Figurative or literary language minor Understanding the question
The enjoyment is shown in images rather than stated: “vegetable companions,” “the tenderness of home gardeners” and fruits “pirouetting around the spacecraft.” (Graesser, Singer & Trabasso, 1994; Kintsch, 1998)
Strategy: Read each of the five sentences in its paragraph and work out whose actions or opinions it reports, then keep the two that show both parts of the idea: astronauts in space, and their enjoyment.
Traps
- Supports only part of the claim: In a question about evidence: a line that backs one half of the claim but not the other, or a related point rather than the claim itself.
- Word match: Repeats striking words or phrases from the text, so it looks supported, but its meaning does not fit the question.
- Reads too much in: A reasonable-sounding conclusion that goes further than the text allows.
The wrong answers, classified
A Supports only part of the claim (King et al., 2004; Thissen, Steinberg & Fitzpatrick, 1989)
Hears a love of fresh food in “missing that crunch,” but these are Spencer’s words about packaged meals, a related point rather than a sign the crew enjoyed the experiment.
D Word match (Freedle & Kostin, 1993)
Is drawn by “a little spice in their life,” which sounds like fun and names the astronauts, though it is Bosland explaining a choice about the peppers’ heat.
E Reads too much in (Graesser, Singer & Trabasso, 1994)
Reasons that Spencer would not urge growing plants “from day one” unless crews loved it, though she gives her own view as a scientist and says nothing about their feelings.
B Twists what the text says (King et al., 2004)
Left out by students who take “the team” to be Spencer’s project team on Earth, though only the crew aboard the station could open the habitat’s door every day.
Working it out, step by step
Figure out what the question asks
You need two sentences from paragraphs 5–9 that show the astronauts enjoyed the experiment. Each one must do two things. It must be about the astronauts in space, not the scientists on Earth. And it must show they liked the work. On the test you click two sentences in the passage. Here, you choose two of the five choices. Both must be right.
Find who each sentence is about
- A is Spencer, a scientist on Earth, talking about packaged food.
- B says “the team” opened the habitat every day.
- C says “they” played with the peppers on harvest day.
- D is Paul Bosland, the scientist who made the seeds, talking about spice.
- E is Spencer again, giving her own opinion.
So only B and C could be about the astronauts. But who is “the team” in B?
Work out who the team is
Paragraph 5 calls Spencer “part of the project team,” and she works on Earth. So the team in paragraph 6 might seem to be the scientists. But look at what the team did. They “cracked open the door of the APH every day.” The APH is a plant box on the space station, so only the crew could open it. The next sentence says they batted the peppers “around the ISS,” so they were on board. Paragraph 1 also calls the crew Mark Vande Hei’s “team.” “Spencer says” only means she is telling us what they did.
See how they show enjoyment
In B, the team checked on “their vegetable companions with all the tenderness of home gardeners.” Companions are friends. Tenderness is gentle, loving care. They treated the plants almost like pets. In C, the same team “batted their bounty around the ISS, taking selfies.” Bounty means a big harvest. They were “delighting,” or taking great joy, in watching the peppers spin like dancers.
Rule out the other three
- A is wrong. Spencer is saying packaged food lacks crunch. That is her view of the food, not the crew enjoying the work.
- D is wrong. “A little spice in their life” sounds fun. But it is Bosland explaining why the peppers have some heat.
- E is wrong. Spencer says crews should grow plants “from day one.” That is a scientist’s advice, not the crew’s feelings.
Watch out: D names the astronauts and sounds cheerful. But the speaker is a scientist on Earth.
Choose the answers
Both sentences show the crew in space caring for and playing with their plants. So the answers are B and C: B, “Spencer says the team cracked open the door of the APH every day to observe their vegetable companions with all the tenderness of home gardeners.” And C, “When harvest day came, they batted their bounty around the ISS, taking selfies and delighting in watching the fruits pirouetting around the spacecraft.”
Why this answer and not the closest wrong one
The hard part is B. It says “the team,” and Spencer was on a team too. But only the crew on the station could open the habitat every day, so B is about the astronauts. D sounds fun, but Bosland is a scientist explaining spice. It says nothing about how the crew felt.
