CAPE CANAVERAL, FL – NASA and rocket partner United Launch Alliance (ULA) have given the GO to proceed with final launch preparations for the agency’s $2.7 Billion Mars 2020 Perseverance Rover following a successful conclusion to the Launch Readiness Review (LRR) held this morning at NASA’s Kennedy Space Center (KSC) in Florida. The goal is to search for signs of past microbial life.
At T Minus 3 days “everything is GO for launch” of the nuclear powered Red Planet rover now targeted for Thursday morning July 30 from the Florida Space Coast.
And the Sunshine State weather looks like it will cooperate – with an 80% chance of acceptable conditions for launch – at this time.
“The launch readiness review is complete and we are indeed ‘go’ for launch,” NASA Administrator Jim Bridenstine announced during the prelaunch press conference this morning the Kennedy Space Center in Florida. “This has been an amazing team effort.”
“I just want to say that the launch readiness review is complete and we are ‘go’ for launch.” Administrator @JimBridenstine shares the latest for the July 30 launch of our @NASAPesereve rover. #CountdownToMars https://t.co/JXscvTFIRt pic.twitter.com/yVEHYrHq4J

The car-sized Perseverance Mars 2020 rover is targeted for liftoff on NET 30 July 2020 at 7:50 a.m. EDT (1150 GMT) aboard a United Launch Alliance (ULA) Atlas V 541 rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station, Florida.
The approximately overall month-long launch window for the Mars 2020 Perseverance rover mission currently extends until August 15.
“We are literally chomping at the bit to take this nuclear powered dune buggy out to Mars,” said ULA CEO Tory Bruno at the KSC briefing.
“I cannot tell you how thrilled we are to lift @NASAPersevere. @ulalaunch & its heritage rockets have taken every US mission to Mars, but this one is arguably the most sophisticated & in some ways the most exciting of all of them.” – @ToryBruno #CountdownToMars pic.twitter.com/2RHPTIC9P6

“The ULA and NASA Launch Readiness Review is complete and everything is progressing toward the ULA Atlas V launch carrying the Mars 2020 mission for NASA,” said ULA.
You can watch the launch live on NASA TV.

Today’s forecast shows an 80 percent chance of favorable weather conditions for launch.
The two-hour launch window on Thursday July 30 extends until 9:50 a.m. EDT.
The U.S. Air Force 45th Weather Squadron is predicting an 80% chance of favorable weather conditions for Thursday’s launch.
The primary weather concerns are cumulus and thick clouds.

In case of a delay the weather odds rise to 90% GO for a 24 hour delay to Friday and return 80% GO for a 48 hour delay to Saturday.
The next big event leading to launch will be rollout of the powerful and venerable ULA Atlas V rocket at Space Launch Complex-41 Tuesday morning July 28 starting around 10 a,m. ET from the 30 story tall Vertical Integration Facility (VIF) to the launch pad.

But it has been a struggle for the NASA, JPL and ULA team to get to the launch of this historic mission even more then normal due to the devastating impact of the COVID-19 coronavirus pandemic
Listen to these comments from NASA Administrator Jim Bridenstine:
“We are in extraordinary times right now with the coronavirus pandemic, and yet we have, in fact, persevered,” Bridenstine said. “And we have protected this mission because it is so impor
The historic mission has remained on track, despite unprecedented challenges from a worldwide pandemic.
The rover’s astrobiology mission, developed under NASA’s Mars Exploration Program, will search for signs of past microbial life.
“We’re doing transformative science; really for the first time, we’re looking for signs of life on another planet,” said Matt Wallace, deputy project manager, NASA’s Jet Propulsion Laboratory.
The Perseverance Mars 2020 mission will search for signs of past microbial life, characterize Mars’ climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.
Ingenuity, a twin-rotor, solar-powered helicopter attached to the belly of the rover, will become the first aircraft to fly on another world.
“I just couldn’t be happier to be here today and have this amazing mission on top of a rocket and ready to go,” said Thomas Zurbuchen, associate administrator, NASA’s Science Mission Directorate, at the briefing.
“From this launch readiness review … all the issues are addressed and we are in fact ready now; we’re just counting down and really celebrating with the team.”
After a seven month long interplanetary journey she is scheduled to touch down in an area of Mars known as Jezero Crater on Feb. 18, 2021. The 28-mile-wide (45-kilometer) crater is home to an ancient dried-up river delta and a lake that once filled it.
Perseverance is a robotic scientist weighing about 2,260 pounds (1,025 kilograms).
The rover is equipped with seven different scientific instruments and 25 cameras.
Earlier this month NASA’s $2.7 Billion Perseverance Mars rover was at last joined to the top of the mighty United Launch Alliance (ULA) Atlas V rocket that will hurl it from our Home Planet to the Red Planet as soon as the end of this month – on a breathtaking mission dedicated to the search for signs of life beyond Earth.
And just days ago last week the rovers nuclear power source known as the MMRTG was installed.
The MMRTG is basically the life blood of the Perseverance rover
The MMRTG is essentially a nuclear battery that uses the heat from the natural radioactive decay of plutonium-238 to generate about 110 watts of electricity at the start of a mission – and slowly declines over time.
The Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) is provided by the U.S. Department of Energy.
