What if space junk and climate change become the same problem?

Story highlights A study presented last month at the European Conference on Space Debris says that the problem has been underestimated, and that the amount of space junk in orbit could, in a worst-case scenario, increase 50 times by 2100 It is easy to compare the space junk problem to climate change. Human activities leave too many dead satellites and fragments of machinery discarded in Earth orbit. If left unchecked, space junk could pose significant problems for future generations rendering access to space increasingly difficult, or at worst, impossible. Yet the two may come to be linked. Our planet’s atmosphere naturally pulls orbiting debris downward and incinerates it in the thicker lower atmosphere, but increasing carbon dioxide levels are lowering the density of the upper atmosphere, which may diminish this effect. A study presented last month at the European Conference on Space Debris says that the problem has been underestimated, and that the amount of space junk in o

What if Space Junk and Climate Change Become the Same Problem? Changes to the atmosphere caused by carbon dioxide emissions could increase the amount of debris that stays in orbit.

China Autonomous Driving Simulation Industry Chain Report, 2020-2021: AD Scenario Generator Debuts, and the Built-in Scenario Library Covers 4,000 Scenarios

Share this article Share this article ResearchAndMarkets.com s offering. Autonomous Driving Simulation Research: Foreign giants build closed-loop simulation platforms, while domestic companies focus on the construction of scenario library In the development of high-level autonomous driving, the importance of simulation testing becomes more and more apparent. From 2020 to 2021, both foreign and domestic companies stepped up the layout in the field of autonomous driving simulation. Foreign simulation giants are committed to building closed-loop simulation platforms for setting up industrial barriers In the transition from industrial simulation to autonomous driving simulation, giants such as Ansys and Siemens have established various modules of autonomous driving simulation through continuous acquisition, cooperation and technological development, strengthened the closed-loop of the simulation platform, and built industrial barriers. At present, the layout of foreign leading comp
