Multistage rocket Lunch

The following video shows a multistage rocket being lifted up. The "slow motion" capture of the dynamics really excites me.




The Saturn V was a multistage liquid-fuel expendable rocket used by NASA's Apollo and Skylab programs from 1967 until 1973. In total NASA launched thirteen Saturn V rockets with no loss of payload. It remains the largest and most powerful launch vehicle ever brought to operational status from a height, weight and payload standpoint.

The largest production model of the Saturn family of rockets, the Saturn V was designed under the direction of Wernher von Braun at the Marshall Space Flight Center in Huntsville, Alabama, with Boeing, North American Aviation, Douglas Aircraft Company, and IBM as the lead contractors. The three stages of the Saturn V were developed by various NASA contractors, but following a sequence of mergers and takeovers all of them are now owned by Boeing.

Global Warming and Atmospheric Brown Clouds

Global warming and climate change are global problems. Eventhough, the countries and people who have not contributed anything for these environmental problems they have to face the impact of these problems equally.

Professor V Ramanathan is one of the best scientist working on climate change and global warming. His latest research describes Asian Brown Clouds (ABCs) which is very important in terms of global warming. In this video he talks about global warming, climate change and specific to ABCs which is a threat to Asia.

This is a long video (54min) of his lecture at UC Davis. I definitely recommend you to watch full video which helps to better understand the latest problem we are facing.
