What about the technology of the previous Kali Yugas?

I dont know about technologies of Previous Kali yugas. But there is a verse in bhagavatam, which predicts about humans going to other planets by manipulation of Maya(or material elements) in this kali yuga.

(S.B 2.7.37)

deva-dviṣāṁ nigama-vartmani niṣṭhitānāṁ  pūrbhir mayena vihitābhir adṛśya-tūrbhiḥ lokān ghnatāṁ mati-vimoham atipralobhaṁ  veṣaṁ vidhāya bahu bhāṣyata aupadharmyam

Here are two translations

Translation 1:

When the atheists, after being well versed in the Vedic scientific knowledge, annihilate inhabitants of different planets, flying unseen in the sky on well-built rockets prepared by the great scientist Maya, the Lord will bewilder their minds by dressing Himself attractively as Buddha and will preach on subreligious principles

Translation 2:

For those who became well informed on the path of education but envious with the divine, roam the worlds and the ether with inventions of Maya [or with modern technology], He will dress up most attractively and [as the Buddha and His representatives] by extensive discourses bewilder their minds with the use of many terms deviating from the tradition.
