LISA Pathfinder - Path to SEL1 Credit: ESA

En route to nothing

It's official! LISA Pathfinder is safely en route to a virtual point in space called the Sun-Earth Libration Point 1 (SEL1), 1.5 million km from Earth. A main engine burn during the weekend provided the thrust needed...

LISA Pathfinder spotted!

On the evening of 8 December, LISA Pathfinder was spotted in orbit by a team from DEIMOS Space, working at a new observatory located in Spain: We received a note from Noelia Sánchez-Ortiz, one of the observers,...

LISA Pathfinder orbit manoeuvres: so far, so good!

Three done, three to go! These updates were sent in by LISA Pathfinder Spacecraft Operations Manager Ian Harrison Monday evening and this morning, reporting on the results of the Nos. 2 and 3 apogee-raising engine burns (referred...

This image was created using data from the Relativistic Electron-Proton Telescopes on NASA's twin Van Allen Probes. It shows the emergence of a new third transient radiation belt. The new belt is seen as the middle orange and red arc of the three seen on each side of the Earth. Image Credit: APL, NASA

Getting to where we want to go: LISA Pathfinder’s...

To travel to SEL1, LISA Pathfinder must raise its apogee to be near the 1.5-million-km point and to do so the spacecraft will perform a sequence of 'apogee raising manoeuvres' providing a velocity increment of more than...
