Its main construction was completed between and , although the station continually evolves to include new missions and experiments. It has been continuously occupied since Nov. As of April , individuals from 19 countries have visited the International Space Station. Top participating countries include the United States people and Russia 50 people.
Astronaut time and research time on the space station is allocated to space agencies according to how much money or resources such as modules or robotics that they contribute. The ISS includes contributions from 15 nations. Related: International Space Station: Live updates. Current plans call for the space station to be operated through at least , with the partners discussing a possible extension until Afterwards, plans for the space station are not clearly laid out.
It could be deorbited, or recycled for future space stations in orbit. Other international mission control centers support the space station from Japan, Canada and Europe. The Space Station flies at an average altitude of miles kilometers above Earth. In one day, the station travels about the distance it would take to go from Earth to the moon and back.
The space station can rival the brilliant planet Venus in brightness and appears as a bright moving light across the night sky. It can be seen from Earth without the use of a telescope by night sky observers who know when and where to look.
Orbital develops and manufactures small space and rocket systems for commercial, military and civil government customers. The company's primary products are satellites and launch vehicles, including low-orbit, geosynchronous and planetary spacecraft for communications, remote sensing, scientific and defense missions; ground- and air-launched rockets that deliver satellites into orbit; and missile defense systems that are used as interceptor and target vehicles.
Orbital also offers space-related technical services to government agencies and develops and builds satellite-based transportation management systems for public transit agencies and private vehicle fleet operators. In addition to food and other supply goods the ATVs can also transport scientific equipment, replacement parts and experiments to the ISS.
The vehicle consists of one section for the drive and the avionics - the electronic steering devices. In addition it has a load-bearing segment, permanently under pressure, in which dry freight is conveyed. Astronauts enter the pressurised segment when unloading and loading the ATV from the station. After separating itself from the upper stage the ATV performs the required rendezvous and docking manoeuvre at the space station by itself, monitored by the ATV control centre in Toulouse.
This is necessary from time to time as the space station is continuously slowed down by the resistance of the residual atmosphere and loses around metres a day in orbit height. At the end of the mission the ATV will be loaded with up to 6. After undocking from the ISS it will re-enter Earth's atmosphere under supervision and finally burn up over the Pacific.
Seasoned space agencies, high-tech consortia, sovereign nations without space programs, media and travel companies, funded entrepreneurs and sponsored inventors, and future-minded investors all have a place on Orbital Reef.
The Orbital Reef team of experts brings proven capabilities and new visions to provide key elements and services, including unique experience from building and operating the International Space Station:.
A vibrant business ecosystem will grow in low Earth orbit, generating new discoveries, new products, new entertainments, and global awareness. Shirtsleeve environment, great visibility, automated guidance, and advanced precision manipulators will make external operations cost-effective and routine. Comprising more than a dozen leading academic institutions with expertise in space and microgravity research, the University Research Advisory Council will focus academic community needs, stimulate research, advise novice researchers, evolve standards of conduct, and lead STEM outreach.
