This gas's low solubility in blood makes it a risk during rapid decompression or EVA

N2

100

This spacecraft completed a successful landing on Mars in 2021 

Perseverance Rover

100

This is what NASA’s TLX tool measures

Subjective workload across six subscales (e.g., effort, frustration)

200

This is the typical atmospheric pressure maintained inside space habitats like the ISS 

101 kPA

200

This is the number of humans who have been on the moon.

200

This system experiences "orthostatic intolerance" upon return to Earth 

Cardiovascular

200

This was the objective of the DART mission launched in 2021 

To test asteroid deflection by crashing into a moonlet

Endsley's SA model breaks situation awareness into these three levels

perception, comprehension, and projection

300

This type of radiation poses the highest risk to astronauts on long-duration missions 

Solar Particle Events


300

This term describes the alignment of 3 celestial bodies

Syzygy

300

This bone loss rate is typical for astronauts on long-duration missions without countermeasures

1-2% per month

300

This rocket is used for Artemis missions

SLS (space launch system)

300

This dimension of trust forms due to feelings or emotions, rather than logical thinking.

Affective

400

This component removes trace contaminants like formaldehyde from cabin air 

Trace Contaminant Control System (TCCS)

400

These components comprise the nucleus of a comet

Ice, dust, and organic materials

400

This type of muscle fiber, which is crucial for endurance and postural stability, is most affected by the lack of gravity in space, leading to significant atrophy during long-duration missions

Type I (slow-twitch) muscle fibers

400

She was the first female commander of the ISS

Peggy Whitson

In the NASA-TLX workload index, this dimension reflects the mental and perceptual activity required by the task

Mental demand

First proposed in 1929, this type of space settlement is a hollow non-rotating spherical shell 10 mi (16 km) in diameter, with a target population of 20,000 to 30,000 people.

Bernal Sphere

During spaceflight, astronauts experience changes in their immune system, which includes a reduction in the effectiveness of these immune cells, responsible for defending the body against viruses and cancerous cells

T Cells

500

This was the first spacecraft to enter interstellar space

Voyager 1

500

SA can degrade due to this phenomenon, where attention is fixated on a single element to the detriment of overall understanding

Attentional Tunneling
