Orbit around l2
WebTerra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS view the entire Earth's surface every 2 days, acquiring data in 36 spectral bands (see MODIS Technical Specifications ). WebWebb's orbit around L2 is known as a halo orbit which, rather than a single path, is an orbit that periodically varies through a series of paths around L2. Arrival at L2 Orbit By design, the launch vehicle and Webb's trajectory put Webb on a path to an L2 orbit with only small inputs needed to refine it. As it separates from the upper stage of ...

WebDec 29, 2024 · To match a Halo orbit around L2 such as the JWST uses, would require a small amount more departure delta-v, and very very little (<50m/s) of arrival delta-v. The JWST will actually not slow down when it gets near its Halo Orbit, but will speed up by another tiny bit, to insert itself into the orbit. Share Improve this answer Follow Although the L1, L2, and L3 points are nominally unstable, there are quasi-stable periodic orbits called halo orbits around these points in a three-body system. A full n-body dynamical system such as the Solar System does not contain these periodic orbits, but does contain quasi-periodic (i.e. bounded but not precisely repeating) orbits following Lissajous-curve trajectories. These quasi-periodic Lis…

The distance between Webb and L2 varies between about 250,000 and 830,000 kilometers (150,000 - 500,000 miles).
