@jaketapper I’m an AARP Advocate and I have a Q for the debate: Ask Trump to outline the details of his plan which will replace Obamacare and where I can read it myself.

@jeffreykluger Just read your Time article about the Tiangong-1 reentry. Very nicely done, and the most accurate synopsis I have read.

@AerospaceCorp predicts TIROS 2, 9th oldest satellite still in orbit, will reenter this week: http://t.co/UoeTUhpWM4 #reentry #spacedebris

@SKM_Moose It was fast, but they had to only 90 minutes to work with.

@SCte7e @AerospaceCorp Yes, but the risk is very low. Collision avoidance info is provided a few hours before launch for many missions.

@jadepixel Approximately 400 tracked objects (>5 cm) per year reenter. Here is a chart showing the count per year.

@SKM_Moose No, based upon today's debris environment, it would take decades #askaerospace

[Roger Thompson @DrRCThompson]

Tracked objects in orbit: active satellites (green) and space debris (red).
