NASA will proceed with development of the Prima space telescope, with the mission budget capped at $1.2 billion.[^1]

Prima is built to observe the cold, dusty universe in far-infrared wavelengths. This spectral band cannot be seen by the James Webb Space Telescope.[^2][^3]

The mission will cover a blind spot between the operating range of Webb and ground-based radio dishes.[^4] The stated budget does not include launch costs.

## What this stands on

1. NASA has capped Prima's budget at $1.2 billion, not including the actual rocket launch, which is a fraction of the roughly $10 billion spent on the James Webb Space Telescope. ([Mashable](https://mashable.com/science/nasa-prima-far-infrared-telescope), News)

3. Alexandra Pope, who will lead the mission's science team, stated that Prima is necessary because the James Webb Space Telescope cannot see the far-infrared part of the spectrum. ([Mashable](https://mashable.com/science/nasa-prima-far-infrared-telescope), News)
4. Prima will fill a blind spot in humanity's view of space by targeting the band of light between the James Webb Space Telescope and ground-based radio dishes. ([Mashable](https://mashable.com/science/nasa-prima-far-infrared-telescope), News)
