LISA Pathfinder Media Briefing

About

The media briefing is organised by the European Space Agency at the European Space Astronomy Centre (ESAC) in Villanueva de la Cañada, Madrid, Spain, on Tuesday, 7 June, 11:30–13:00 CEST. Doors open at 11:00 CEST. Launched in December 2015, LISA Pathfinder travelled to its operational orbit, 1.5 million km from Earth towards the Sun, where it started its scientific mission on 1 March. At the core of the spacecraft, two identical gold–platinum cubes, are being held in the most precise freefall ever produced in space. Over the first two months of scientific operations, the LISA Pathfinder team has performed a number of experiments on the test masses to prove the feasibility of gravitational wave observation from space. These results will be presented at the media briefing.

Lisa Pathfinder mission overview LISA Pathfinder will pave the way for future missions by testing in flight the very concept of 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. LISA Pathfinder will use the latest technology to minimise the extra forces on the test masses, and to take measurements. The inertial sensors, the laser metrology system, the drag-free control system and an ultra-precise micro-propulsion system make this a highly unusual mission. LISA Pathfinder is an ESA mission, which will also carry a NASA payload.

LISA Pathfinder launch animation Artist’s impression of the launch of LISA Pathfinder, ESA’s technology demonstration mission that will pave the way for future gravitational-wave observatories in space. Scheduled to lift off on a Vega rocket from Europe’s Spaceport in French Guiana in December 2015, LISA Pathfinder will operate at the Lagrange point L1, 1.5 million km from Earth towards the Sun. After launch, the spacecraft will take about eight weeks to reach its operational orbit around L1. The Vega rocket is designed to take small payloads into low-Earth orbit. The animation shows the rocket shortly after launch, rising above our planet and releasing the fairing.
