The next Atlas V to initiating a mission to Mars is initially effect, as United Commence Alliance (ULA) moved thru “Commence Automobile on Stand (LVOS)” operations for NASA’s Mars 2020 mission. The preparations are being conducted at Dwelling Commence Advanced-41 or SLC-41 at Cape Canaveral Air Drive Field (CCAFS).
The pad float has begun no longer long after the rocket had arrived in Florida.
The booster arrived into the Cape from Decatur, Alabama on Might per chance well simply 18 on an Antonov-124, flown by Volga-Dnepr Airlines.
Assuredly, ULA’s transport ship, called the R/S RocketShip – launched in 1999 and became once beforehand identified as the M/V Delta Mariner – delivers the booster to the Cape. Alternatively, since the ship became once in the Pacific Ocean at the time, the chartered airplane became once utilized.

Once the Atlas V booster became once offloaded from the Antonov-124, it became once moved from the CCAFS Skid Strip to the Atlas Spaceflight Operations Heart. It became once kept there except the booster became once mandatory for LVOS operations at SLC-41.
After the booster became once in effect next to the VIF, a cell crane raised the booster off of the trailer. Then, an overhead crane atop the VIF and the ground dealing with fixture slowly raised the 107-foot booster to the vertical effect.
The crane then assisted the Atlas V booster additional into the VIF. Rapidly after the booster became once lowered onto its effect on the Cell Commence Platform (MLP). ULA technicians then secured the booster to the MLP itself.
Earlier in Might per chance well simply, the MLP and SLC-41 nominally launched america-7 mission for the United States Dwelling Drive. The mission carried the high-secret Boeing X-37B spaceplane on an Atlas V 501.
SLC-41 beforehand launched the Titan III and Titan IV rockets, with the first initiating being in 1965. The complex has been exclusively aged for Atlas V launches since the Sizzling Chicken 6 initiating in 2002, which became once the inaugural Atlas V initiating.
The introduction of the Atlas V in 2002 marked a dramatic shift in the Atlas rocket family. No longer like the old Atlas III variant, the Atlas V does no longer order tension stabilized tanks. As a substitute, the Atlas has as what ULA calls a “fundamental-core” booster.

In 2021, one more evolution in ULA’s rocket family will possible be on-line, as the Vulcan rocket conducts its inaugural initiating from SLC-41.
The Atlas V for the Mars 2020 mission will skim in the 541 configuration, which manner that the rocket will sport a five meter fairing, four Aerojet Rocketdyne AJ-60 precise rocket motors, and one Aerojet Rocketdyne RL-10 engine on the Centaur III upper stage. The serial number for this Atlas V rocket is AV-088.
The Centaur upper stage has been aged since its first initiating on an Atlas rocket in Might per chance well simply 1962. Alternatively, fancy the Atlas rocket, the Centaur has undergone a host of modifications. The RL-10 engine runs on Liquid Hydrogen and Liquid Oxygen. Centaur will proceed to skim even after Atlas has been retired in the have of the improved Centaur V on the Vulcan rocket.
The Aerojet Rocketdyne AJ-60s will sooner or later get replaced by GEM-63 precise rocket motors that are being built by Northrop Grumman.
The Atlas V configuration for Mars 2020 is the identical that became once aged for the Mars Science Laboratory (MSL/Curiosity) mission, which landed the rover at Gale Crater in 2012. The invent for the Perseverance rover is in step with the invent that became once aged for Curiosity.
Alternatively, no longer like the Curiosity rover, Perseverance can even lift an experimental helicopter, called Ingenuity.
ULA and its heritage firms bask in launched every single United States mission to Mars. The predominant two American missions to Mars, Viking 1 and a couple of also launched from SLC-41.

Diversified previous Mars missions launched by ULA consist of the Mars Exploration Rovers Spirit and Replacement, and the most modern NASA mission to Mars, Insight.
At this time, the Perseverance rover is located at the Payload Perilous Servicing Facility at NASA’s Kennedy Dwelling Heart.
The rover has been integrated with Ingenuity and the Descent and Entry Automobile assemblies.

In the impending weeks, extra preparations will possible be utilized on the Atlas V inside of the VIF. The Centaur III upper stage will possible be rolled over to the VIF at SLC-41. The the same goes for the four Aerojet Rocketdyne AJ-60s, that can be hooked up to the first stage booster.
The encapsulated payload will come at the VIF at SLC-41 after the boosters and the Centaur III is integrated into the Atlas V rocket.
The pre-initiating time desk has been on a severe route, given the COVID-19 mission. The Mars 2020 mission has to develop the July 17 to Aug 11 initiating window for the mission to attain Mars in Feb 2021.
If all goes to position, the touchdown effect for the Perseverance rover is Jezero Crater.
