Our Space Launch System (SLS) rocket is coming together at the agency’s Kennedy Space Center in Florida this summer. Our mighty SLS rocket is set to power the Artemis I mission to send our Orion spacecraft around the Moon. But, before it heads to the Moon, puts it together right here on Earth.
How do crews assemble a rocket and spacecraft as tall as a skyscraper? The process all starts inside the iconic Vehicle Assembly Building at Kennedy with the mobile launcher. Recognized as a Florida Space Coast landmark, the Vehicle Assembly Building, or VAB, houses special cranes, lifts, and equipment to move and connect the spaceflight hardware together. Orion and all five of the major parts of the Artemis I rocket are already at Kennedy in preparation for launch. Inside the VAB, teams carefully stack and connect the elements to the mobile launcher, which serves as a platform for assembly and, later, for fueling and launching the rocket.
Because they carry the entire weight of the rocket and spacecraft, the twin solid rocket boosters for our SLS rocket are the first elements to be stacked on the mobile launcher inside the VAB. Crews with ’s Exploration Ground Systems and contractor Jacobs team completed stacking the boosters in March. Each taller than the Statue of Liberty and adorned with the iconic “worm” logo, the five-segment boosters flank either side of the rocket’s core stage and upper stage. At launch, each booster produces more than 3.6 million pounds of thrust in just two minutes to quickly lift the rocket and spacecraft off the pad and to space.

In between the twin solid rocket boosters is the core stage. The stage has two huge liquid propellant tanks, computers that control the rocket’s flight, and four RS-25 engines. Weighing more than 188, 000 pounds without fuel and standing 212 feet, the core stage is the largest element of the SLS rocket. To place the core stage in between the two boosters, teams will use a heavy-lift crane to raise and lower the stage into place on the mobile launcher.
On launch day, the core stage’s RS-25 engines produce more than 2 million pounds of thrust and ignite just before the boosters. Together, the boosters and engines produce 8.8 million pounds of thrust to send the SLS and Orion into orbit.
Once the boosters and core stage are secured, teams add the launch vehicle stage adapter, or LVSA, to the stack. The LVSA is a cone-shaped element that connects the rocket’s core stage and Interim Cryogenic Propulsion Stage (ICPS), or upper stage. The roughly 30-foot LVSA houses and protects the RL10 engine that powers the ICPS. Once teams bolt the LVSA into place on top of the rocket, the diameter of SLS will officially change from a wide base to a more narrow point — much like a change in the shape of a pencil from eraser to point.

Next in the stacking line-up is the Interim Cryogenic Propulsion Stage or ICPS. Like the LVSA, crews will lift and bolt the ICPS into place. To help power our deep space missions and goals, our SLS rocket delivers propulsion in phases. At liftoff, the core stage and solid rocket boosters will propel Artemis I off the launch pad. Once in orbit, the ICPS and its single RL10 engine will provide nearly 25, 000 pounds of thrust to send our Orion spacecraft on a precise trajectory to the Moon.
When the Orion stage adapter crowns the top of the ICPS, you’ll know we’re nearly complete with stacking SLS rocket for Artemis I. The Orion Stage Adapter is more than just a connection point. At five feet in height, the Orion stage adapter may be small, but it holds and carries several small satellites called CubeSats. After Orion separates from the SLS rocket and heads to the Moon, these shoebox-sized payloads are released into space for their own missions to conduct science and technology research vital to deep space exploration. Compared to the rest of the rocket and spacecraft, the Orion stage adapter is the smallest SLS component that’s stacked for Artemis I.
Finally, our Orion spacecraft will be placed on top of our Moon rocket inside the VAB. The final piece will be easy to spot as teams recently added the bright red “worm” logotype to the outside of the spacecraft. The Orion spacecraft is much more than just a capsule built to carry crew. It has a launch abort system, which will carry the crew to safety in case of an emergency, and a service module developed by the European Space Agency that will power and propel the spacecraft during its three-week mission. On the uncrewed Artemis I mission, Orion will check out the spacecraft’s critical systems, including navigation, communications systems, and the heat shield needed to support astronauts who will fly on Artemis II and beyond.

The path to the pad requires many steps and check lists. Before Artemis I rolls to the launch pad, teams will finalize outfitting and other important assembly work inside the VAB. Once assembled, the integrated SLS rocket and Orion will undergo several final tests and checkouts in the VAB and on the launch pad before it’s readied for launch.
The Artemis I mission is the first in a series of increasingly complex missions that will pave the way for landing the first woman and the first person of color on the Moon. The Space Launch System is the only rocket that can send astronauts aboard ’s Orion spacecraft and supplies to the Moon in a single mission.

# #Artemis #Moon #Space Launch System #rocket science #space #space exploration #exploration #spaceflight #Orion spacecraft #Artemis I #Kennedy Space Center #Vehicle Assembly BuildingThe arrival of “Valorant’s” Act 2, which launches on August 4, brings with it a fresh battle pass and a colorful new set of skins. But the biggest piece of Act 2 news is the introduction of a new game mode: free-for-all deathmatch.
The mode, which will feature 10 players, no cap on money to buy weapons and no abilities, will launch August 5, a day after Act 2 goes live. Players start with heavy armor and the option to buy any available weapon. Upon spawning, they receive an eight-second invulnerability buff to protect them as they select weapons, which can be exchanged for different weapons at any time. Players are respawned dynamically, after three seconds, in locations that are close (but not too close) to combat, outside of the line of sight of enemies and with their backs to a wall.
Several mechanics have been implemented to discourage camping in rat corners. A UAV sweeps over the map every five seconds, revealing the locations of all players on the map. Upon death, players drop a health pack that fully restores player health and shields that can only be picked up by running it over.

The objective is to reach 30 kills; otherwise, the match ends after 6 minutes. Players can quit the match at any time, though they won’t receive XP if they do.
Act 2 will also include a new skinpack, Glitchpop, named after its glitchy holographic visual elements. The skins are among the brightest and flashiest present in the game thus far, a clear differentiation from the current, more staid and serious skins. Glitchpop skins are available for the Frenzy pistol, the Judge shotgun, the Odin LMG, the Bulldog rifle and a melee weapon. The bundle, which also includes a glitchpop card, gun buddy and spray, will cost 8, 700 VP, “Valorant’s” in-game currency (which comes out to roughly $90).
“Valorant’s” Act 2 battle pass, which costs 1, 000 VP ($10), will include skins, gun buddies, sprays, player cards, titles and Radianite points, similar to the Act 1 battle pass.

“It should feel like lots of value for the $10 price point, ” said Sean Marino, art lead on Valorant at Riot Games. “For the Act II pass, we decided to look a lot more at how the community responded to the quality of the Act I content. Which cosmetics made players the most happy? What do they want to see more of? Did players feel like there was enough variety for them to express themselves? We tried to include some stuff the community had asked for (bring back the chicken spray!), add more variety (less food-related buddies), create more fun buddies (the toaster and cat were popular), and build off some of the Act I content (like more Tactibear).”
