NRO wasn't kidding about 101's "Elvish script" on the mission patch / payload fairing. "Goodness persists" isn't even there in English!

Weather 90% GO for Tuesday's Launch

Preparations are continuing for Tuesday's launch of the Atlas V rocket on the NROL-101 mission at 5:58 p.m. EST (2258 UTC) from Cape Canaveral, Florida.

The latest forecast from the 45th Weather Squadron indicates a 90 percent chance of favorable conditions for liftoff, according to Launch Weather Officer Jessica Williams. An exceedance of the ground wind limit is the only concern.

"For launch day Tuesday, strong high pressure over the northern Gulf states weakens and moves east into the Carolinas. In response, winds will be from the northeast and decrease to 15-20 knots. The onshore winds will bring scattered stable stratocumulus clouds with no threat of Range Weather Lightning Launch Commit Criteria violations," the launch weather team says.

The operations forecast includes scattered low-level clouds at 4,000 feet, good visibility, northeasterly winds 15 to 20 knots and a temperature near 71 degrees F.

If the launch is delayed to Wednesday for some reason, there is a 70 percent chance of good conditions.

"For backup day Wednesday, the pressure gradient tightens and winds increase from the east-northeast, with gusts near 26 knots likely into the evening. Continued onshore flow will bring the potential for a few Cumulus Clouds. The primary concerns for backup day are Ground Winds and the Cumulus Cloud Rule," forecasters report.

Цитата: ULANew solid motors coming to Atlas in evolution to Vulcan Centaur
Jul 21, 2020, 06:10 AM

Building on the legacy of over a thousand Graphite Epoxy Motors (GEMs) that powered Delta rockets for 30 years, ULA has taken delivery of its first GEM 63 boosters from strategic partner Northrop Grumman to introduce a new era of solid motor propulsion into the Atlas V rocket system and prepare for Vulcan Centaur.

GEMs are strap-on motors that burn solid propellant and augment the lifting capacity of rocket's first stage. The original design, called GEM 40s because of their 40-inch diameter, began flying on the Delta II rocket in 1990. A second generation of 46-inch GEMs yielded the Delta II Heavy. A third generation, called GEM 60, was successfully used by Delta IV Medium+ rockets.

Now, the GEM 63s are ready to debut aboard the Atlas V rocket starting with the NROL-101 mission later this year. The three motors for that mission recently arrived at Cape Canaveral to await integration onto the rocket's first stage.

This fourth generation of GEMs is a direct evolution of the boosters used by Delta, rooted in the knowledge, manufacturing processes and materials of the earlier motors.

The GEM 63s measure 63 inches in diameter and 66 feet in length. They will be ignited at the launch pad and burn for 94 seconds, each consuming 97,500 pounds of propellant to produce 373,800 pounds of max thrust to augment the 860,200 pounds of thrust produced by the RD-180 main engine to power the Atlas V rocket skyward.

They have undergone successful qualification test-firings on the ground at the Northrop Grumman facility in Utah and the factory is in full production.

GEM 63s are a lower-cost alternative to the solid rocket boosters that have been used by Atlas V since 2003, yet deliver the same level of thrust and lift-capacity to enable replacement. They also offer a streamlined process for attaching them to the launch vehicle at the Vertical Integration Facility.

What's more, the upcoming Atlas V launches with the new motors will build flight experience in preparation for using GEM 63XLs on Vulcan Centaur's first flight.

The XL variant will stand 72 feet tall, contain 105,800 pounds of propellant and generate 455,400 pounds of thrust each. They will be the longest single-segment solid rocket motors ever built.

Atlas V can be fitted with as many as five GEM 63s, the Vulcan Centaur can incorporate up to six GEM 63XLs, depending on the weight of the payload and its orbital destination. All motors will have stationary nozzles.

They are manufactured using state-of-the-art automation and robotics. The cases are filament wound by computer-controlled winding machines using high-strength graphite fiber and durable epoxy resin.

ULA entered a long-term strategic partnership with Northrop Grumman in 2015 to become the sole provider of solid rocket boosters for Atlas V and Vulcan Centaur.

It's Rollout Day!

Welcome to Rollout Day for the United Launch Alliance Atlas V with NROL-101. The rocket will move from the Vertical Integration Facility to the pad at Space Launch Complex-41 in preparation for liftoff Tuesday at 5:58 p.m. EST (2258 UTC) in service to the U.S. Space Force and National Reconnaissance Office.

Weather Acceptable for Rollout

Final preparations are underway for this morning's rollout of the United Launch Alliance Atlas V rocket from its assembly building to the pad at Cape Canaveral's Space Launch Complex-41. 

The transfer will cover a distance of one-third-of-a-mile and position the rocket on the launch pad for Tuesday's countdown and liftoff on the NROL-101 mission for the National Reconnaissance Office.

A weather briefing from Launch Weather Officer Jessica Williams of the 45th Weather Squadron has verified conditions are acceptable for the move, which is expected to begin shortly. Skies are mostly clear with just some scattered clouds, winds are brisk but within allowable limits and there's no threat of heavy rain or lightning today.

Go to Roll

A readiness check of systems' status by ULA Launch Conductor Scott Barney has been completed satisfactorily, and ULA Launch Director Tom Heter III has authorized the rollout to begin.

Pre-roll preps are complete and the weather is acceptable to move the 206-foot-tall rocket on its Mobile Launch Platform to the launch pad.

"Stand Engineer, proceed with MLP transport to pad," Barney radioed to Issac Spence at the VIF.

We are standing by to initiate the roll.

Rollout Underway

Rollout of the Atlas V rocket to launch NROL-101 is underway with first motion of the Mobile Launch Platform (MLP) departing the Vertical Integration Facility (VIF).

The VIF is a 30-story building where the rocket stages and payload were put together for this mission aboard the Mobile Launch Platform. The MLP will travel to the pad with the help of undercarriage railcars and trackmobile machines that push the entire 1.7-million-pound platform and Atlas V 531 rocket along tracks up the hill to the pad.
