Fantasy or si-fi book recs

I genuinely need book recommendations that give off project hail mary vibes, I absolutely loved the science and the descriptions of everything and it was such a good book and the friendship between grace and rocky was so amazing. I need to read more books like this and I absolutely adored the fact it had zero romance, I find it so hard to find a good book like that now and days and I 100% need more like it. I dont mind a little romance subplot but it actually has to be good and not be the main plot. Please and thank you give me your book recommendations like PHM 🌌✨️
