RADAR

RADAR was an acronym for 'RAdio Detection And Ranging' or 'Remote Aerial Detection And Ranging'. It was a sensing technique used on Earth in the 20th and 21st centuries. By projecting radio waves and analyzing any reflected waves, RADAR devices could attempt to identify the heading, speed, size, altitude, distance, and even shape of the object which reflected them.
In the late 24th century, the and starships were equipped with radar technoloogy. The location of the radar control room or the radar technology in the ships were labeled on the master situation display. ()
In 2258 of the alternate reality, the bridge of the , the simulator for the had a Markey RADAR monitor. ()
In 2267, the became ensnared in the gravitational field of a black star while en route to Starbase 9 for resupply. By using the warp engines in full reverse, the ship managed to escape but was subsequently flung back in time to 1969 Earth, where it was detected by Technician who worked at a United States Air Force RADAR installation. ()
Following a brief battle with the Federation timeship Aeon in 2373, the was pulled into a temporal rift whereby it was transported to Earth in the year 1996. Upon realizing this, Captain Kathryn Janeway instructed Tom Paris to maintain a high orbit and modulate the shields to scatter any RADAR beams emanating from the surface or orbital satellites.
Lieutenant B'Elanna Torres later configured the shields of a Class 2 shuttle to disguise its visual profile from RADAR using an interferometric dispersion when she and Commander Chakotay conducted a low altitude flight in an attempt to beam up Henry Starling. To any observer, the shuttle appeared to be a small 20th century aircraft. ()
In an alternate 2374, Commander Chakotay noted at the dedication of Voyagers new astrometrics lab "before there were maps and globes, let alone RADAR and subspace sensors, mariners navigated by the stars." ()

RNA

Ribonucleic acid (RNA) is a substance found in all living s which acts as a controller of protein synthesis. It is similar in construction to its counterpart deoxyribonucleic acid (DNA), with the replacement of ribose for deoxyribose and the pyrimidine uracil for thymine. RNA also commonly acts as the genome for the majority of viruses, rather than DNA.
In 2154, Doctor Phlox managed to identify an RNA sequence that could act as an off switch for the Klingon augment virus. ()
Following his exposure to a quantum fissure in 2370, Worf's cellular RNA was thrown into a state of flux which extended to the subatomic level. This was the first clue to the nature of Worf's quantum disassociation; essentially, he was in the wrong quantum reality. ()
The RNA of the Dominion's Teplan blight virus was found to be difficult to recreate, thus hindering vaccination efforts. ()

Rabbit

A rabbit, sometimes called a bunny rabbit, was a type of mammal native to the planet Earth. It was distinguished by long ears, long hind legs for jumping, and a short, fluffy tail. ()
In 1986 at the Feinberg's Loan and Pawn in San Francisco, the image of a rabbit could be seen as part of the artwork on a tapestry hanging on the wall next to the stairs. ()
In 2000, there was a stuffed rabbit at Alexandria Books in Portage Creek, Indiana. ()
In 2022 Khan Noonien Singh had a drawing depicting a rabbit and a cow near a house, ()
In 2259 of the alternate reality, Lucille Harewood had a stuffed toy rabbit. ()
That same year in the prime universe, when the crew of the was trapped in a musical reality due to a quantum uncertainty field from a subspace fold; La'an Noonien-Singh was wondering if the changing laws of physics would cause them to magically "poof into bunnies." Joseph M'Benga then said he would prefer not to turn into a bunny. Spock then tells them that he doubts everyone would transform into bunnies. ()
In 2365 during an encounter with the Ferengi, William T. Riker told Jean-Luc Picard that "we're all here – anxiously waiting for you to pull another rabbit out of your hat.", referring to a magician's trick. Ezri Dax used the same expression in 2375 on AR-558. That same year, Miles O'Brien twisted the expression, saying to Dr. Julian Bashir, "You're not going to pull a rabbit out of your medkit." He was referring to Bashir's failure to find a cure for the morphogenic virus. (; )
In 2367, two science officers replicated a stuffed rabbit for their son. ()
The next year, Data and Guinan were looking at nebula clouds and finding shapes in them, and Data told her that "it is clearly a bunny rabbit." ()
Clara Sutter had a stuffed rabbit among her belongings in her room. ()
In 2372 in Quark's on Deep Space 9, Dr. Bashir pulled a piece of latinum from Quark's ear, a trick taught to him by Jadzia Dax, he told Kira Nerys that "next time I want to pull a rabbit out of his ear." ()

Radial velocity

Radial velocity was the velocity of a target along the line of sight of an observer. In general, this could also be the velocity of an object along a radial line from the origin of a with a radial coordinate. Examples of such a coordinate system were the and coordinate systems. For this definition, the quantity had the of length per unit time.
This quantity was also the around the yaw, pitch or roll axis, or a combination of angular velocities around these axes. Under this definition, the quantity had the dimensions of angle per unit time. ()
In 3190, scans made by the sensors of the recorded the radial velocity of Deep Space Repair Beta Six as 22 degrees per second. After repairs were made to the station, the radial velocity had dropped down to 38%. ()
== Background Information ==
When the Discovery finds Deep Space Repair Beta Six, the station was shown tumbling out of control, with both () motion and () motion, with the angular motion looking like a combination of yaw, pitch, and roll. Tilly quantified the tumbling, saying, "Scans show the station moving at 720 kilometers per second with a radial velocity of 22 degrees per second."
And after she, Tal, Nalas and his crew got the station's thrusters working, and the station's rotation was shown to decrease, she asked Burnham for confirmation that all the thrusters were working, and in reply, Burnham reported, "Radial velocity's decreased to 38% and counting."
So, the radial velocity that Tilly and Burnham mentioned is, in the real world, not radial velocity, but angular velocity.
On the other hand, two other characters used real-world terms to describe the angular motion of the station: Nalas said, "Well, I can fix thrusters, that'll stop the ."
And Owosekun said, "I can get coordinates within an acceptable margin of error if Keyla can match speed and rotation." In the real world, speed is a and is the same as the of velocity, while velocity is a with both magnitude and direction, and with the appropriate adjective, the term "speed" can be used for both linear and angular motion as in "linear speed" and "angular speed," but "speed" is usually used by itself to mean "linear speed." So, by "speed and rotation," Owosekun meant "linear speed and rotation" (or for consistency in physical concepts, "linear and angular speeds" or "translation and rotation").
In addition, since Tilly provided only the magnitudes but not the directions for the linear and angular velocities she reported, then she was really giving only linear and angular speeds.

Radiara

Radiara was one of the s, a photonic species from the Veraflex nebula, and the child of Orb leader Spheronius. Though its species were long-standing enemies of the s, it began an illicit romantic relationship with Quadralon, child of Cube leader Sexagus.
In 2382, Radiara accompanied Spheronius to the for peace talks with the Cubes, whereupon it disappeared to engage in rigorous sex with Quadralon. After trashing Quadralon's quarters, the pair sneaked off to the holodeck, leaving the scene to be discovered by Lieutenant jg Beckett Mariner and Ensign Olly.
With the children of both the Orb and Cube leaders apparently missing, tensions between the species escalated until a shape war erupted on the ship. After the Cerritos stopped the fighting by draining both sides of energy, Radiara and Quadralon reappeared and announced their union to all. They also presented their new hybrid child, SquAaron, who enchanted its grandparents and paved the way to a lasting peace. ()
