NASA’s Mars Perseverance rover is now attached to the rocket that will carry it on its seven-month journey to the Red Planet for the agency’s Mars 2020 mission.

On Tuesday, July 7, a team of engineers fastened the payload fairing, containing the rover and remainder of the spacecraft – the aeroshell backshell, descent stage and cruise stage – to a United Launch Alliance (ULA) Atlas V booster inside the Vertical Integration Facility (VIF) at Cape Canaveral Air Force Station’s Space Launch Complex 41 in Florida. The rocket’s upper stage and spacecraft will remain attached until about 55 minutes after launch, after which the two will separate, sending Perseverance on its solo journey to Mars.

With the spacecraft and booster now connected, final testing of the two – separately and together as one unit – can begin. Once those tests are complete, the rocket will leave the VIF on the morning of July 28 for its journey to the launch pad – just 1,800 feet away.

NASA and United Launch Alliance are now targeting Thurs., July 30, at 7:50 a.m. ET, with a two-hour window, for launch of the Mars 2020 mission. The team identified the cause of the issue with the liquid oxygen sensor line found during Wet Dress Rehearsal (WDR). A small leak was located in the weld of the line, which has been repaired and tested.

The rover, carrying seven different scientific instruments, is slated to arrive at the Red Planet on Feb. 18, 2021, regardless of what day it lifts off during the launch period. During its time on Mars, Perseverance will search for signs of past microbial life and collect rock and soil samples of the Martian surface for future return to Earth.

The mission, managed by NASA’s Science Mission Directorate and the Jet Propulsion Lab (JPL), will provide key insight into some of the challenges associated with future human exploration of Mars. NASA’s Launch Services Program based at Kennedy Space Center is managing the launch.

Due to launch vehicle processing delays in preparation for spacecraft mate operations, NASA and United Launch Alliance have moved the first launch attempt of the Mars 2020 mission to no earlier than July 30. A liquid oxygen sensor line presented off-nominal data during the Wet Dress Rehearsal, and additional time is needed for the team to inspect and evaluate. Flight analysis teams have expanded the mission launch opportunities to August 15 and are examining if the launch period may be extended further into August.

NASA’s Launch Services Program Prepares for Upcoming 2020 Missions

NASA’s Launch Services Program (LSP) is ringing in the New Year with three planned science missions in 2020, aimed at studying the Sun, Mars and our oceans. The first two missions will be launching from Cape Canaveral Air Force Station in Florida, while the third will launch from Vandenberg Air Force Base in California.

Launching in February, Solar Orbiter is a collaborative mission between the European Space Agency (ESA) and NASA, which will study the Sun, its outer atmosphere and the solar wind. The spacecraft, developed by Airbus Defence and Space, will provide the first-ever images of the Sun’s poles. The Solar Orbiter spacecraft will launch aboard a United Launch Alliance (ULA) Atlas V 411 rocket, and liftoff is scheduled for Feb. 5. LSP will manage the launch.

NASA’s Mars 2020 mission is targeting to launch in July. Established under the agency’s Mars Exploration Program, the mission will send a rover to the Red Planet to search for signs of ancient microbial life. It also will help us better understand the planet’s geology, collect rock and soil samples that can later be returned to Earth and test new technologies that could pave the way for future human exploration of Mars.

The rover is being manufactured at the agency’s Jet Propulsion Laboratory in California and will be sent to NASA’s Kennedy Space Center in mid-February. The rover will launch on a ULA Atlas V 541 rocket, procured by LSP, and is expected to land on Mars on Feb. 18, 2021.

Sentinel-6/Jason CS (Continuity of Service), the final mission of 2020, is projected to launch later in the year and will observe global sea level changes. The mission – a collaboration between ESA and NASA – aims to collect high-precision ocean altimetry measurements using two consecutive and identical satellites. The Sentinel-6 mission will launch from California on a SpaceX Falcon 9 rocket.

“LSP is incredibly excited to execute the 2020 launch manifest,” said Tim Dunn, LSP launch director. “Additionally, LSP will provide advisory expertise for four Commercial Crew Program missions and four Commercial Resupply Services program missions – all in support of the International Space Station. Also, throughout the year, LSP will be launching numerous CubeSat missions, focused on making space accessible to educational institutions.”

Mars 2020 Rover’s Heat Shield, Back Shell Arrive at Florida Spaceport

Two vital pieces of equipment for the Mars 2020 rover were flown from Lockheed Martin Space in Denver, Colorado and recently delivered to the agency’s Kennedy Space Center.

The rover’s heat shield and back shell arrived at Kennedy’s Launch and Landing Facility (formerly the Shuttle Landing Facility) on Dec. 11, 2019, and were then transported to the Florida spaceport’s Payload Hazardous Servicing Facility. Built by Lockheed Martin Space, these two essential parts of the spacecraft will protect the rover during its passage to Mars. The Mars 2020 rover is being manufactured at NASA’s Jet Propulsion Laboratory (JPL) in California and, once complete, will be delivered to Kennedy in mid-February, 2020.

As the spacecraft descends through the Martian atmosphere, the heat shield will encounter extreme amounts of friction, creating temperatures as high as about 3,200 degrees Fahrenheit. The back shell contains several elements critical to landing the rover, including the parachute and antennas for communication. Some of these key components will be integrated in the months to come by the NASA-JPL team at Kennedy.

The mission is scheduled to launch in the summer of 2020 from Cape Canaveral Air Force Station aboard a United Launch Alliance Atlas V 541 rocket, procured by NASA’s Launch Services Program. It will land on the Red Planet on Feb. 18, 2021.

About the size of a car with dimensions similar to the Curiosity rover, the Mars 2020 rover will carry seven different scientific instruments. Developed under NASA’s Mars Exploration Program, the mission aims to search for signs of past microbial life, characterize the planet’s climate and geology, collect samples for future return to Earth and pave the way for human exploration of Mars.
