"Semper Supra" is named after the U.S. Space Force's official motto, Semper Supra. [1] After the creation of the U.S. Space Force on December 20, 2019, United States Air Force Senior Airman Daniel Sanchez – who researched the mottos of other military branches and chose "Semper Supra" because of both its ease of pronunciation and the alliteration of both the Latin phrase and its English ...
Rotation and Interior Structure Experiment (RISE) is a radio science experiment onboard InSight Mars lander that will use the spacecraft communication system to provide precise measurements of Mars' rotation and wobble. RISE precisely tracks the location of the lander to measure how much Mars's axis wobbles as it orbits the Sun.
Several factors make placing a spacecraft into an areostationary orbit more difficult than a geostationary orbit. Since the areostationary orbit lies between Mars's two natural satellites, Phobos (semi-major axis: 9,376 km) and Deimos (semi-major axis: 23,463 km), any satellites in the orbit will suffer increased orbital station keeping costs due to unwanted orbital resonance effects.
The U.S. Space Force -- the newest military branch, which was established in 2019 -- officially adopted its own song titled "Semper Supra" on Tuesday.
Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
Space Force unveiled its official song and phew boy is it cringey. It's a chorus singing lyrics about the limitless sky and "the watchful eye" of the "guardians beyond the blue." It's just not great.
Mars spins a little more quickly each year, according to data collected by NASA’s now-retired InSight lander. ... The instruments were used to track Mars’ rotation during the mission’s first ...
A celestial object's axial tilt indicates whether the object's rotation is prograde or retrograde. Axial tilt is the angle between an object's rotation axis and a line perpendicular to its orbital plane passing through the object's centre. An object with an axial tilt up to 90 degrees is rotating in the same direction as its primary.
