Alberto Rosende, commanding general, 63rd Readiness Division located at the Army Reserve Center in Mountain View, Calif., speaks to the Soldiers, Families, Civilians within the 63rd RD Seven-State Southwestern region of the U.S. On the resources available on the various 63rd RD social media platforms and website regarding the Corona virus (COVID-19). 63 synonyms, 63 pronunciation, 63 translation, English dictionary definition of 63. 63 - being three more than sixty lxiii, sixty-three cardinal. Motorsport is where our performance comes from. One proof: The new Mercedes-AMG GLC 63 S 4Matic+ SUV. Its AMG 4.0 liter V8 biturbo engine, the fully variable AMG Performance 4MATIC+ all-wheel drive and the AMG Speedshift MCT 9G automatic transmission are perfectly in tune with each other: This is how it holds the lap record on the legendary Nordschleife as currently the fastest MID-size SUV. Tips for next year. File your return on time, even if you will owe taxes. If necessary, you can make a payment plan to pay what you owe. Filing on time saves you money because it costs the Internal Revenue Service less money to process your return when it's filed on time.

Get to Know Your Neighborhood Coordination Officers
Find your sector. Find your NCOs.
Neighborhood Coordination Officers, or NCOs, are your local problem solvers. They spend all their working hours within the confines of their assigned sectors, actively engaging with local community members and residents. They get to know the neighborhood, its people, and its problems extremely well.
Use the map and list below to find your sector and your NCOs. Feel free to email your officers directly, or contact your local precinct, to discuss ongoing crime or quality-of-life issues.

The Graphite-Epoxy Motor (GEM) is a series of solid rocket boosters fueled by HTPB and produced by Northrop Grumman Innovation Systems with a carbon-fiber-reinforced polymer casing.[1] GEM series boosters were previously used on the Delta II, Delta III, and Delta IV. They will fly on the Atlas V and Vulcan.
Active variants[edit]
GEM-63[edit]
The GEM-63 is being developed as a drop-in replacement for the Aerojet RocketdyneAJ-60A booster used on the Atlas V. The Atlas V began flying the GEM-63 in 2020 with the NROL-101 launch.
GEM-63XL[edit]
The GEM-63XL is about 5 feet longer than the regular GEM-63 and will be used on the Vulcan launch vehicle starting in 2021.[2][3]
GEM-63XL offers higher performance at almost half the cost of the AJ-60A boosters currently being used on the Atlas V.[4]

Retired variants[edit]
GEM-40[edit]
The GEM-40 is a 40-inch-diameter (1,000 mm) SRM used on Delta II beginning in 1990. The use of composite materials allowed for booster casings lighter than the steel casings of the Castor 4 SRMs they replaced.[9] The first flight of a GEM-40 occurred in 1990 on a Delta II 7925.[10] Delta II vehicles can use three, four, or nine GEM-40s. When using three or four boosters, all GEM-40s ignite on the ground, while on Delta IIs using nine boosters six are ignited on the ground, and the remaining three are ignited in the air when the first six burn out.[11]
Failures[edit]
On August 5, 1995, an air-lit GEM-40 failed to separate from a Delta II 7925 carrying Koreasat 1. The excess mass of the booster resulted in the satellite reaching a lower than intended transfer orbit, which it was able to compensate for using on-board propellant.[12]
On January 17, 1997, a Delta II (Delta 241) exploded due to a catastrophic failure in a GEM-40. The failure triggered the launch vehicle's self-destruct function 13 seconds after ignition. An Air Force investigation determined that the motor's casing had been damaged prior to launch, resulting in the casing splitting open soon after ignition.[12]
GEM-46[edit]
The GEM-46 was a lengthened 46-inch-diameter (1,200 mm) solid motor originally developed for Delta III. This solid motor variant also included thrust vector control (TVC) to help steer the vehicle. After the discontinuation of the Delta III, GEM-46 motors (without TVC)[11] were used on the Delta II to create the Delta II Heavy, which could only be launched from a modified pad at Cape Canaveral.[13] Both Delta III and Delta II-Heavy used nine GEM-46s, with six ignited on the ground and three air-lit.[14][15]
631 Area Code
GEM-60[edit]
The GEM-60 was a 60-inch-diameter (1,500 mm) solid motor used on the Delta IV family of launch vehicles, available with and without Thrust Vector Control (TVC).[11] A Delta IV Medium+ can use two or four GEM-60s,[16] and was retired after the launch of a GPS-III satellite which launched on 22 August 2019.[17]
