1. Spaceflight

   Spaceflight (or space flight) is an application of astronautics to fly spacecraft into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflight operates either by telerobotic or autonomous control. The more complex human spaceflight has been pursued soon after the first orbital satellites and has reached the Moon and permanent human presence in space around Earth, particularly with the use of space stations. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs, with currently the International Space Station as the main destination of human spaceflight missions while China's Tiangong Space Station is under construction. Spaceflight is used for placing in Earth's orbit communications satellites, reconnaissance satellites, Earth observation satellites, but also for space exploration such as space observatories and space probes, or even for space tourism. Spaceflight can be achieved with different types of launch systems, conventionally by rocket launching, which provide the initial thrust to overcome the force of gravity and propel a spacecraft from the surface of the Earth. Once in space, the motion of a spacecraft—both when unpropelled and when under propulsion—is covered by the area of study called astrodynamics. Some spacecraft remain in space practically indefinitely, which has created the issue of space pollution in the form of light pollution and space junk, which is a hazard to spaceflight. Otherwise spacecraft are terminated by atmospheric reentry, in which they disintegrate, or if they do not, their reentry is mostly controlled to safely reach a surface by landing or impacting, often being dumped in the oceanic spacecraft cemetery. As such spacecraft have been the subject of some space traffic management.

1. Spaceflight

   Spaceflight is ballistic flight into or through outer space. Spaceflight can occur with spacecraft with or without humans on board. Examples of human spaceflight include the Russian Soyuz program, the U.S. Space shuttle program, as well as the ongoing International Space Station. Examples of unmanned spaceflight include space probes which leave Earth's orbit, as well as satellites in orbit around Earth, such as communication satellites. These operate either by telerobotic control or are fully autonomous. Spaceflight is used in space exploration, and also in commercial activities like space tourism and satellite telecommunications. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other earth observation satellites. A spaceflight typically begins with a rocket launch, which provides the initial thrust to overcome the force of gravity and propels the spacecraft from the surface of the Earth. Once in space, the motion of a spacecraft—both when unpropelled and when under propulsion—is covered by the area of study called astrodynamics. Some spacecraft remain in space indefinitely, some disintegrate during atmospheric reentry, and others reach a planetary or lunar surface for landing or impact.

Examples of spaceflight in a Sentence

1. Stephen Bowen:

   It’s another paradigm shift, those two events — huge events — in spaceflight happening during our increment, on top of all the other work we get to do, I don’t think we’re going to fully be able to absorb it until after the fact.

2. Thomas Boothby:

   Ultimately this information will give us insights into how one of the toughest organisms on Earth is able to survive the rigors of spaceflight, and our hope is that these insights will provide avenues for developing countermeasures or therapies that will help safeguard astronauts during prolonged space missions.

3. Rosie Farrar:

   Leanne Caret's flying for everyone on our team who took on the challenge of human spaceflight and said,' We can do it,'.

4. Mike Leinbach:

   Spaceflight is like any other big engineering system, you get smart by successes. You get smart by failures. ... It’s an evolution.

5. Jamie Foster:

   Animals, including humans, rely on our microbes to maintain a healthy digestive and immune system, we do not fully understand how spaceflight alters these beneficial interactions. The UMAMI experiment uses a glow-in-the-dark bobtail squid to address these important issues in animal health.
