What is Jason-3 and why is it important to oceanography?

Jason-3 is a satellite mission that supports scientific, commercial and practical applications related to sea level rise, ocean circulation, and climate change. Jason-3 follows the current operational altimeter satellite, Jason-2, in maintaining satellite altimetry observations of global sea surface height.

What does the Jason-3 satellite measure?

What kind of measurements will Jason-3 take? Jason-3 is designed to measure sea level, as well as wave height and ocean surface wind speeds globally, every 10 days.

What does the Poseidon 3B altimeter instrument used to measure the height level of oceans?

radar altimeter
The Poseidon-3B Altimeter is a radar altimeter that maps sea surface topography used to calculate ocean surface current velocity, wave height, and wind speed.

What is the flagship satellite of NASA’s Earth science missions?

The International Space Station
ISS. The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000.

What features are mapped by the Topex Poseidon satellite?

Mapped global tides for the first time. Monitored effects of currents on global climate change and produced the first global views of seasonal changes of currents. Monitored large-scale ocean features like Rossby and Kelvin waves and studied such phenomena as El Niño, La Niña, and the Pacific Decadal Oscillation.

How does radar altimeter work?

A radar altimeter (RA), radio altimeter (RALT), electronic altimeter, or reflection altimeter measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft.

What three things does the satellite the Topex Poseidon monitor?

TOPEX/Poseidon

Measured sea levels with unprecedented accuracy to better than 5 cm.
Continuously observed global ocean topography.
Monitored effects of currents on global climate change and produced the first global views of seasonal changes of currents.

When was the launch of the Jason 3 satellite?

Jason-3 is the follow-on altimetry mission of Jason-2 / OSTM (launch June 20, 2008) led by the operational agencies: NOAA, EUMETSAT, and CNES.

What is the objective of the Jason 3 mission?

The objective of the Jason-3 Mission is to provide continuity to the unique accuracy and coverage of the TOPEX/Poseidon, Jason-1 and OSTM/Jason-2 missions in support of operational applications related to extreme weather events and operational oceanography and climate applications and forecasting. 1) 2) 3)

Where did the Falcon 9 launch Jason 3?

The Jason-3 payload was deployed into its target orbit at 830 mi (1,340 km) altitude after an orbital insertion burn about 56 minutes into the flight. It was the 21st Falcon 9 flight overall and the second into a high-inclination orbit from Vandenberg Air Force Base Space Launch Complex 4E in California.

What kind of propellant does Jason 3 use?

Jason-3 is three-axis stabilized and nadir pointing – maintained by reaction wheels and magnetic torque rods. Power (580 W) is provided by two solar panels. A hydrazine propellant system is being used for orbital maintenance. Jason-3 has a launch mass of about 550 kg; the design life is 5 years.
