Not exact matches

The reason they are common and predictable is that the moon orbits the Earth once every 29 days and at a 5 degree angle to plane at which the Earth orbits the sun (if it didn't have this angle, EVERY full moon would be a total lunar eclipse).

In lunar orbit, it occurred to me that, here we are, all the way up there at the moon, and we're studying this thing, and it's really the Earth as seen from the moon that's the most interesting aspect of this flight.»

Orbiting at 100 kilometers above the lunar surface, KAYUGA transmits laser pulses to the moon with its laser altimeter (LALT).

And the retro - rockets must fire at exactly the right moment to put the spacecraft into lunar orbit.

«Planetary science will completely change once we get crew beyond low Earth orbit,» says David Kring, a senior staff scientist at the Lunar and Planetary Institute.

Then in 2011, Goddard engineer Donald Dichmann, who at the time worked for Applied Defense Solutions in Columbia, Md., and his co-authors began work on a paper reviewing the trade studies NASA made when it decided to move its Interstellar Boundary Explorer from its original orbit to a more stable position at another lunar - resonant orbit — P / 3 — where it's mapping the boundary between the solar system and interstellar space.

Specifically, the paper reported that at lunar - resonant orbits, perturbations from the gravitational tug - and - pull exerted on spacecraft by the Moon and Earth are roughly zero, especially if the spacecraft's apogee is about 90 degrees with respect to the Moon.

Apollo lunar astronauts are four to five times more likely to die from cardiovascular disease than astronauts who never left Earth's orbit or who never flew at all, according to a study published in Scientific Reports today that considered about 100 astronauts, seven of them Apollo.

I wonder if Bigelow Aerospace is looking at this experiement for applications to their orbiting and lunar habitats?

A NASA station at White Sands, New Mexico, picked up the signal — the first - ever laser transmission from lunar orbit.

In addition to the nonsensical lunar - orbiting project, its budget projects spending $ 7.5 billion over the next three years on preparing the Space Launch System (SLS) for its first flight, when we already have SpaceX's Falcon Heavy, which can lift 70 percent of the SLS payload at one - tenth the cost.

Mosaic of photos taken of the far side of the moon by the Lunar Reconnaissance Orbiter, orbiting at an altitude of just 30 miles (50 km).

Creating a moonscape at the Moon Bar, an open air garden lounge, silk pendants orbit above the circular bar, designed using lunar - toned materials of sliced stone and black pebbles.

Although the total lunar eclipse (when the Moon passes through earth's shadow) and the Super Moon (time it is the closest to earth in it's orbit and therefore looks bigger) happened this morning at around 7:30, there is another notable lunar phenomenon happening tonight as well.

I saw of graph of the precession cycle once and it appeared to occasionally skip a beat — perhaps when eccentricity got near zero — this makes some intuitive sense at least... (cause of Obliquity cycle is less obvious than precession of axis; perhaps some contribution comes from the Earth - Moon orbit and Earth + Moon — Sun orbit not being in the same plane — although the Moon's orbit will «average» near the plane of the Earth - Sun orbit over a relatively short time, but there's lunar orbit eccentricity, etc,... residuals might build up...?
