NASA’s EO-1 Retires After 17 Years

The Earth Observing-1 satellite launched in November 2000 is finally set to be decommissioned after an impressive run of seventeen years. We take a look at some of it’s achievements.

Reality Check!

From Einstein’s theory of relativity to the remarkable discovery of gravitational waves, a century-long ride.   Intro 100 years after it was first published, Einstein’s theory of relativity has emerged copiously triumphant in the wake of the recent direct detection of gravitational waves. Einstein said that everything is relative. Gravity isn’t exactly a downward force, time is not absolute and it’s all about ‘spacetime’. Was...

Frozen Orbits

Frozen orbits about the Earth – counteracting orbital perturbations in the long run A special type of orbit that is cleverly chosen such that the variation in the mean Kepler elements under the influence of Earth’s irregular gravity field is minimized. There are six intuitive orbital components that are often used to describe the shape and orientation of a satellite orbit. These elements are varying constantly due to...

“Juno, welcome to Jupiter”

After 2.7 billion kilometers and almost 5 years, Juno successfully entered Jupiter’s orbit in the early hours of today morning. Subsequent to NASA’s Galileo mission (1995), Juno is only the second to have accomplished this feat. While in orbit, the Juno mission aims to better understand the gas giant in the following 20 months of its science phase. Juno also happens to be the fastest ever craft built by humans, travelling...

Emerging Victorious: The LISA Pathfinder

The LISA (Laser Interferometer Space Antenna) Pathfinder is a research spacecraft of the European Space Agency (ESA) and was launched in December 2015. The main purpose of the LISA Pathfinder mission is to test certain technologies for future space observatories to detect gravitational waves from large astronomical bodies (e.g. stars) around us. The LISA Pathfinder uses extremely sophisticated technology to observe the...
