1. reentry

   Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: uncontrolled entry, such as the entry of astronomical objects, space debris, or bolides; and controlled entry (or reentry) of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric entry, descent, and landing of spacecraft are collectively termed as EDL. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Reentry has been achieved with speeds ranging from 7.8 km/s for low Earth orbit to around 12.5 km/s for the Stardust probe. Crewed space vehicles must be slowed to subsonic speeds before parachutes or air brakes may be deployed. Such vehicles have high kinetic energies and atmospheric dissipation is the only way of expending this. It is thus highly impractical to use retrorockets for the entire reentry procedure. Ballistic warheads and expendable vehicles do not require slowing at reentry, and in fact, are made streamlined so as to maintain their speed. Furthermore, slow-speed returns to Earth from near-space such as parachute jumps from balloons do not require heat shielding because the gravitational acceleration of an object starting at relative rest from within the atmosphere itself (or not far above it) cannot create enough velocity to cause significant atmospheric heating. For Earth, atmospheric entry occurs by convention at the Kármán line at an altitude of 100 km (62 miles; 54 nautical miles) above the surface, while at Venus atmospheric entry occurs at 250 km (160 mi; 130 nmi) and at Mars atmospheric entry at about 80 km (50 mi; 43 nmi). Uncontrolled objects reach high velocities while accelerating through space toward the Earth under the influence of Earth's gravity, and are slowed by friction upon encountering Earth's atmosphere. Meteors are also often travelling quite fast relative to the Earth simply because their own orbital path is different from that of the Earth before they encounter Earth's gravity well. Most objects enter at hypersonic speeds due to their sub-orbital (e.g., intercontinental ballistic missile reentry vehicles), orbital (e.g., the Soyuz), or unbounded (e.g., meteors) trajectories. Various advanced technologies have been developed to enable atmospheric reentry and flight at extreme velocities. An alternative method of controlled atmospheric entry is buoyancy which is suitable for planetary entry where thick atmospheres, strong gravity, or both factors complicate high-velocity hyperbolic entry, such as the atmospheres of Venus, Titan and the gas giants.

1. reentry

   Reentry generally refers to the act or process of returning or being returned to a previous state, position, or activity. It can have various specific meanings in different contexts such as: 1. In space exploration, it refers to the return of a spacecraft into the Earth's atmosphere from outer space. 2. In criminal justice, reentry is the process of reintegrating into society by individuals released from prison. 3. In medicine, it can refer to a pathologically reactivated conduction pathway in the heart, causing a cardiac arrhythmia. 4. In sociology or psychology, it might refer to the process of readjusting to normal life after a significant time spent in an isolated or different environment, such as after extensive travel or a long stay in a hospital. Yet in all uses, it typically involves some form of transition or adaptation back to a certain condition or state.

Examples of reentry in a Sentence

1. Anthony Fauci:

   You don't want to let up at a time that's premature, but right now we are clearly looking at if we, in fact, are as successful as we hope to be over the extended 30 day period that the President announced several days ago -- namely extending the period of restrictions and guidelines to the end of April -- that if, in fact, we are successful, it makes sense to at least plan what a reentry into normality would look like, that doesn't mean we're going to do it right now.

2. Department Director Bryan Stirling:

   I think our staff has been working hard on safety and security, and we’ve been working hard on getting funding for rehabilitation and reentry programs. There are avenues, if people want to better themselves when they come to the Department of Corrections.

3. Alfredo Montufar-Helu:

   Marvel’s reentry into China after a de facto ban of [more than] three years by Chinese authorities is especially significant given the backdrop against which it is happening, not only is China facing increasing economic headwinds at home, but also a more challenging external environment, driven by growing communication and trust gaps with the West.

4. John Insprucker:

   We demonstrated the ability to transition the engines to the landing propellant tanks, the subsonic reentry looked very good and stable, we've just got to work on that landing a little bit.

5. Jeffrey Lewis:

   I'm someone who thinks that they probably would( survive reentry). There are some people who are somewhat doubtful about that.
