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 ...
MV Shannon, formerly known as MV GO Navigator, is one of SpaceX's two Dragon capsule recovery vessels. Owned by SpaceX through Falcon Landing LLC (which also owns SpaceX's faring recovery vessels and Elon Musk's private jet), this vessel, along with its sister ship, MV Megan, is designed to retrieve Crew and Cargo Dragon capsules after splashdown.
At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years. If the trip is merely to the nearest star, with deceleration the last half of the way, it would ...
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 ...

The amount of debris in low Earth orbit has increased tremendously, putting satellites and the International Space Station in danger of colliding with even the tiniest bits of space junk.
In early 2021, the nets were removed from the two fast ships and SpaceX ended the ship leases, with both ships returned to their owner. 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 ]
Events such as this are rare, with data from the Cruise Lines International Association showing that, on average, 19 people per year fell overboard in the years between 2009 and 2019. Of a total ...
