US Space Agency, NASA’s Magnetospheric Multiscale mission (MMS) has scaled meteoric heights to enter the Guinness World Record for the second time, and this time, for the highest altitude fix of a GPS signal.
MMS, tasked with providing information on the Earth’s magnetosphere and unravelling the lesser known phenomenon called magnetic reconnection, set the record at 70,006.4 kilometres above the Earth’s surface, said NASA.
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 meet. Accurate GPS tracking allows the satellites to maintain a tight formation and facilitate high resolution three-dimensional observations.
MMS set the first record when the four spacecraft flew in a pyramid formation at a distance of just four-and-a-half miles or seven kilometers apart — the closest flying separation ever achieved in any multispacecraft mission.
The MMS mission, which began with the launch of four identical satellites on March 12, 2015, is set to explore the magnetic reconnection process, which can link the sun’s magnetic field lines to Earth’s, funneling material and energy from the sun into Earth’s magnetic environment.

Introducing ElectionsHQ + 50 Ground Reports Project
The 2024 elections might seem easy to guess, but there are some important questions that shouldn't be missed.
Do freebies still sway voters? Do people prioritise infrastructure when voting? How will Punjab vote?
The answers to these questions provide great insights into where we, as a country, are headed in the years to come.
Swarajya is starting a project with an aim to do 50 solid ground stories and a smart commentary service on WhatsApp, a one-of-a-kind. We'd love your support during this election season.
