The Space Shuttle and Space Station will be located in low Earth orbit (LEO), beyond the protection of the atmosphere, but still within the protection of the magnetic field. Webwhich is above 99 percent of the Earth's atmosphere. Depend-ing on aircraft weight, the ER-2 reaches an initial cruise altitude of 65,000 feet within 20 minutes. Typical cruise speed is 410 knots. The range for a normal eight-hour mission is 3,000 nauti-cal miles, yielding seven hours of data collection at altitude. The
Low earth orbit, medium and high earth orbits – Types of orbits (2/3)
WebAtmospheric drag at orbital altitude is caused by frequent collisions of gas molecules with the satellite. It is the major cause of orbital decay for satellites in low Earth orbit.It results in the reduction in the altitude of a satellite's orbit. For the case of Earth, atmospheric drag resulting in satellite re-entry can be described by the following sequence: WebThe semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface).

A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term LEO region is also used … See more A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. Even for circular orbits, the altitude above ground can vary by as much as 30 km (19 mi) … See more The mean orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s (4.8 mi/s), which translates to 28,000 km/h (17,000 … See more The LEO environment is becoming congested with space debris because of the frequency of object launches. This has caused growing concern in recent years, since collisions at … See more 1. ^ Orbital periods and speeds are calculated using the relations 4π R = T GM and V R = GM, where R is the radius of orbit in metres; T is the orbital period in seconds; V is the … See more A low Earth orbit requires the lowest amount of energy for satellite placement.

However, 125 objects were cataloged in orbit with apogees up to 2,200 kilometers.... WebGeosynchronous Orbit (GSO) & Geostationary Orbit (GEO) Objects in GSO have an orbital speed that matches the Earth’s rotation, yielding a consistent position over a single longitude. GEO is a kind of GSO. It matches the planet’s rotation, but GEO objects only orbit Earth’s equator, and from the ground perspective, they appear in a fixed ... charek in elyria
