The Herschel Mission
ESA’s Herschel Space Observatory has the largest mirror ever built for a space telescope. At 3.5-metres in diameter the mirror will collect long-wavelength radiation from some of the coldest and most distant objects in the Universe. In addition, Herschel will be the only space observatory to cover a spectral range from the far infrared to sub-millimetre. Located at L2 (lagrangian point).
Study the formation of galaxies in the early universe and their subsequent evolution
Investigate the creation of stars and their interaction with the interstellar medium
Observe the chemical composition of the atmospheres and surfaces of comets, planets and satellites
Examine the molecular chemistry of the universe
The Planck Mission
Planck will help provide answers to one of the most important set of questions asked in modern science - how did the Universe begin, how did it evolve to the state we observe today, and how will it continue to evolve in the future? Planck's objective is to analyse, with the highest accuracy ever achieved, the remnants of the radiation that filled the Universe immediately after the Big Bang, which we observe today as the Cosmic Microwave Background.
Mapping of Cosmic Microwave Background anisotropies with improved sensitivity and angular resolution
Determination of Hubble constant
Testing inflationary models of the early universe
Measuring amplitude of structures in Cosmic Microwave Background
Earth Orbit about Sun
The LISA Mission
LISA is an ESA-NASA mission involving three spacecraft flying approximately 5 million kilometres apart in an equilateral triangle formation. Together, they act as a Michelson interferometer to measure the distortion of space caused by passing gravitational waves. Lasers in each spacecraft will be used to measure minute changes in the separation distances of free-floating masses within each spacecraft.
To be the first spacecraft to detect gravitational waves
Measure the properties of binary star systems in the Galaxy and beyond
Test General Relativity under extreme conditions
Search for gravitational signature of the Big Bang
The LISA Pathfinder Mission
LISA Pathfinder will pave the way for the LISA mission by testing in flight the very concept of the gravitational wave detection: it will put two test masses in a near-perfect gravitational free-fall and control and measure their motion with unprecedented accuracy. This is achieved through state-of-the-art technology comprising the inertial sensors, the laser metrology system, the drag-free control system and an ultra-precise micro-propulsion system.
LISA Pathfinder is to demonstrate the key technologies to be used in the future LISA mission.
The BepiColombo Mission
BepiColombo will set off in 2013 on a journey lasting approximately 6 years. When it arrives at Mercury in August 2019, it will endure temperatures as high as 350 °C and gather data during its 1 year nominal mission from September 2019 until September 2020, with a possible 1-year extension to September 2021.
