How many GPS satellites are there and when were they put in orbit?
GPS SatellitesThere are 30 GPS satellites -- called NAVSTARs -- in place and the oldest one was launched in 1989. These are just the ones in operation now -- another 22 have been launched since the program started in 1978, but are no longer working. The design of the satellites has remained essentially the same over the years; the differences have just been in their operations.The first 11 satellites, known as Group I and designed by Rockwell International, were launched into orbit between 1978 and 1985 from Vandenburg Air Force Base in California. Each of these satellites contained one Cesium and two Rubidium atomic clocks and could provide navigation and standard positioning information. Continuous contact with the Ground Control Segment (CS) was required for their operation. They were designed to last five years, but most lasted much longer.The next group of 9 satellites are called Group II and were also designed by Rockwell. These were the first to provide precision positioning information for military use and to be able to operate for 14 days without contact with the CS. Group II satellites contained four clocks two Cesium and two Rubidium and were launched between February 1989 and October 1990 from Cape Canaveral Air Force Station in Florida. They were designed to last 7.3 years and two currently remain in operation.The Group IIA satellites were next group to be designed by Rockwell and numbered 19. They are similar to the Group II satellites, except they have the ability to operate 180 days without contact with CS. These were launched from Cape Canaveral between November 1990 and November 1997. All but three of these satellites are still in operation.The most recent type, Group IIR, were designed by Lockheed Martin and each have three Rubidium clocks. They were designed to provide more accurate information through a combination of ranging techniques and communication between the satellites. They are also designed to last slightly longer (7.8 years) and to have improved independent controls. There are currently 12 such satellites in orbit the most recent launched in November 2004.The satellites are launched via a Delta II rocket designed by Boeing. These are expendable launch vehicles (ELVs), meaning they are intended for one use only. Each of these ELVs consists of the following:Stage I which contains fuel and oxygen tanks to supply the main engine during its climb;Solid rocket booster motors to provide additional thrust during the first two minutes of flight;Stage II which contains the fuel and oxidizer tanks that supply the engine needed to insert the ELV into orbit and the brains of the ELV, including its guidance system;Stage III that has a solid rocket motor to provide any needed velocity change.More input from others:According to SMC Fact Sheet (URLhttp://www.losangeles.af.mil/smc/pa/fact_sheets/gps_fs.htm), as well as Garmin (URL http://www.garmin.com/aboutGPS/), there are 24 satellites in the system with an additional 4 on reserve.
What countries were involved in the Magellan space satellite?
It was built by NASA (the US), with contributions from the European Space Agency (France, Germany, Italy, the UK, Spain, Belgium, the Netherlands, Switzerland, Sweden, Denmark, Ireland, Norway, and Austria at the time the Hubble was launched; since then six additional countries (and the European Union as a whole) have joined - in addition, Canada is an "associate member", and has been since the very early days of the ESA).
How much did a gallon of gasoline cost in 1989?
gallon of gas in 1989 was about $1.02
What is the value of a 1989 vladislav tretiak collector plate?
The value of a 1989 Vladislav Tretiak collector plate can vary based on factors such as its condition, rarity, and market demand. Generally, these plates can be found in the range of $20 to $100. However, it's best to check recent sales on platforms like eBay or collector websites for the most accurate pricing. Appraisals from collectors or antique shops can also provide more specific insights.

Have any satellite or Jupiter explored Jupiter and what year?
Launched in 1989, Galileo finally reached Jupiter on December 7, 1995
What spacecraft was deployed in 1989 to study Jupiter?
The spacecraft deployed in 1989 to study Jupiter was the Galileo spacecraft. It arrived at Jupiter in 1995 and carried out extensive investigations of the planet and its moons until it was intentionally crashed into Jupiter in 2003 to eliminate any potential contamination of its moons.
How long it would it take a space traveler to reach Jupiter?
It depends on how fast he's traveling. Pioneer 10 was launched in March 1972 and passed Jupiter in December 1973... a travel time of 21 months. Galileo was launched in October 1989 and did not reach Jupiter until December 1995, over six years later.
What is the name of the space shuttle that launched the Galileo interplanetary probe to Jupiter on STS-34 in October 1989?

When was the 'Galileo' space mission launched what were it's goal?
It was launched on October 18,1989 and arrived December 7, 1995. It was sent to Jupiter to explore the planet and to study it's moons. It had an anttena problem but despite that it was the first do discover an asteroid moon and the first to be in Jupiter's atmosphere.
What are three of the names of the robot explored Jupiter and what year?
Juno: Launched in 2011, Juno reached Jupiter's orbit in 2016 and continues to study the planet's atmosphere and magnetic field. Galileo: Launched in 1989, Galileo arrived at Jupiter in 1995, providing valuable insights into the planet's moons and magnetosphere. Voyager 1: Launched in 1977, Voyager 1 flew by Jupiter in 1979, capturing images and data of the planet and its moons before continuing its journey out of the Solar System.

What spaceship orbited Jupiter?
The spaceship that orbited Jupiter was the Galileo spacecraft. It was launched by NASA in 1989 with the mission to study Jupiter and its moons. Galileo provided valuable data and images of Jupiter and its moons until it was deliberately crashed into the planet in 2003 to avoid contaminating the moon Europa.
Where there astronauts on Galileo?
No, Galileo was an unmanned spacecraft that was launched by NASA in 1989 to study the planet Jupiter and its moons. It did not carry any astronauts on board.
