Ultra-Light Rockets: Key to Russia's Space Constellations
8 Apr
Summary
- Russia plans to launch the 20-meter Voronezh rocket in 2029.
- Ultra-light rockets are essential for replacing retiring satellites.
- Clear Space develops lidars to combat space debris threats.
Russia's new ultra-light Voronezh carrier rocket, measuring 20 meters in length and 2 meters in diameter, is scheduled for its first launch in December 2029. This liquid-fuel rocket is designed to carry up to 400 kg into a 500-km orbit.
The primary function of these ultra-light rockets is to replace aging satellites within constellations. This is a more cost-effective and timely solution compared to using larger rockets, which can involve long waiting times for full capacity or emergency launches.
Development is well underway, with preliminary designs complete and engine manufacturing contracted to UEC-Kuznetsov. This initiative aligns with Russia's strategy to develop its own satellite constellations and ensure security in near-Earth space.
Separately, the company Clear Space is developing space lidars, featuring an AI module, to identify and mitigate threats from the estimated 132 million pieces of space debris. These lidars can also aid in spacecraft docking and inter-satellite communication.
