The percentages of submitted proposals across science categories were:
- Cosmology and Intergalactic Medium 12.2%
- Galaxies 25.6%
- ISM, Star Formation and Planetary Systems 34.8%
- Stellar Evolution 27.4%.
Proposals will be reviewed by the Observing Programmes Committee and the DPR scheme. Proposers can expect to be informed of the outcome of the review process around mid-July.
