I want to find a temperature sensor able to be used from -80 °C to 20 °C, measuring air temperature, with a potentially low pressure, reaching 1 kPa. Another constraint is that it should be as small as possible (a thermistor or TO-92 is small enough, though). Finally, its accuracy should be around 0.5 – 1 °C.
However, all the sensors I've found (mainly thermistors, and chips like the TI LMT87 or Tsic301) are only said to work in temperature above -50 °C.
What sensor could I use ?

You could use a platinum RTD like the PPG102A6. This has a temperature range of -200C to 600C with an accuracy of +/-0.15C
