NASA Satellites Break Guinness World Record

Washington: NASA’s Magnetospheric Multiscale Mission (MMS) has set the Guinness World Record for the highest altitude fix of a GPS signal at 70,000 kilometers above the surface of the Earth.

Operating in a highly elliptical orbit around Earth, the four MMS spacecraft incorporate Global Positioning System (GPS) measurements into their precise tracking systems, which require extremely sensitive position and orbit calculations to guide tight flying formations.

Earlier this year, MMS achieved the closest flying separation of a multi-spacecraft formation with only 7.2 km between the four satellites.

When the satellites are closest to Earth, they move at up to 35,405 km per hour, making them the fastest known operational use of a GPS receiver.

When MMS is not breaking records, it conducts ground-breaking science.

Still, in the first year of its prime mission, MMS is giving scientists new insight into Earth’s magnetosphere.

The mission uses four individual satellites that fly in a pyramid formation to map magnetic reconnection, a process that occurs as the sun and Earth’s magnetic fields interact.

Precise GPS tracking allows the satellites to maintain a tight formation and obtain high-resolution, three-dimensional observations. Understanding the causes of magnetic reconnection is important for understanding phenomena around the universe, from auroras on Earth to flares on the surface of the sun and even areas surrounding black holes.

Next year, MMS will enter Phase 2 of the mission, and the satellites will be sent into an even larger orbit where they will explore a different part of Earth’s magnetosphere.

During that time, experts anticipate the satellites to surpass their current high-altitude GPS record by a factor of two or more.
