This implies that the IMF configurations during upstream events are large-scale spatial structures with radii of curvature of the order of the Earth-L1 distance, i.e., 0.01 AU. These spatial structures are being convected through the L1 point into the Earth's foreshock....
That design led to inconclusive results with mole rats. Now, with their bicycle wheel tunnel system the researchers were able to vary the distance that the mole rats travel between their nest and their food source by creating long routes and short routes. In each trial, the mole rats started...
Transporting this from the moon to L1 requires a delta-v of 2.4 km/sec compared with the delta-v of 12 km/sec from Earth to L1, similarly the delta v from the moon to LEO is 3.4 km/sec using aerobraking as opposed to a delta v of 8 km/sec from Earth to LEO. Although the ...

At the Lagrange point L1 in the Sun-Earth system, the gravitational forces and the centrifugal force of a third body cancel each other. This point is located at 1.5 × 106 km from the Earth, on the line from Earth to the Sun, 1% of the whole distance between the two bodies. A body...
