A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry. A crewed capsule contains the spacecraft's instrument ...
The free-fall time is the characteristic time that would take a body to collapse under its own gravitational attraction, if no other forces existed to oppose the collapse. As such, it plays a fundamental role in setting the timescale for a wide variety of astrophysical processes—from star formation to helioseismology to supernovae —in which ...

SpaceX found that recovery of the fairings floating on the ocean surface was adequate to support economic reuse of payload fairings on subsequent Falcon 9 launches. [ 5 ]
Risk of falling space junk impacting planes is growing, experts warn ... They found that high-density regions immediately around major airports have an 0.8% chance per year of being affected by an ...
The space agency said if a small 130- to 200-foot asteroid entered Earth's atmosphere over a populated area, an airburst could shatter windows or cause structural damage across a city. A larger ...
