On the Pad!

Our Atlas V rocket has arrived at its Cape Canaveral pad for Thursday's launch to Mars.

Over the next few hours today, umbilical connections will be made with launch pad systems, the environmental control system feeding conditioned air to the rocket and payload will be switched to facility supplies to allow the portable trailers used during rollout to be unplugged and moved away.

The Perseverance rover is bound for Jezero Crater, located on the western edge of Isidis Planitia, a giant impact basin just north of the Martian equator at about 18 degrees latitude, 77 degrees longitude. Perseverance's core goal is astrobiological -- to seek signs of ancient microbial life -- and the rover will be landing in a place with high potential for finding these signs. Western Isidis presents some of the oldest and most scientifically interesting landscapes Mars has to offer. Mission scientists believe the 28-mile-wide (45- kilometer) crater was home to a lake 3.5 billions of years ago -- the word "Jezero" in several slavic languages means "lake" -- as well as to an ancient river delta. Together, they could have collected and preserved ancient organic molecules and other potential signs of microbial life from the water and sediments that flowed into the crater billions of years ago.

The seven-hour launch countdown will begin Thursday morning, leading to a liftoff of the Atlas V rocket at 7:50 a.m. EDT (1150 UTC).

Our live countdown updates will begin on this page at 12:15 a.m. EDT (0415 UTC).

The live video webcast of the launch begins at 7 a.m. EDT (1100 UTC) and will be viewable on this page.

Secured at Pad

The MLP has been lowered onto the launch pad piers, accomplishing the "harddown" milestone at 11:23 a.m. EDT. 

This will enable the undercarriages with the attached portable environmental control system trailers to be removed and retreat from the pad later this afternoon.

Weather still 80% GO

The launch weather forecast remains unchanged with an 80 percent chance of favorable conditions to allow liftoff on Thursday afternoon. The outlook calls for just a few low-level and scattered mid-level clouds, good visibility, southwesterly winds 8 to 10 knots and a temperature near 80 degrees F.

The joint ULA and NASA team is wrapping up the planned activities for Rollout Day and the Atlas V rocket is being powered down for the night. The next event will be starting the launch countdown.

The countdown clocks will be positioned at T-minus 6 hours, 20 minutes in anticipation of initiating the countdown on Thursday.

Марсоход Perseverance во время исследований катера Йезеро соберет 40 образцов грунта
Марсоход возьмет в титановые трубки пробы грунта и оставит их на поверхности. Эти пробы соберет другой аппарат, который запустят к планете в 2026 году

НЬЮ-ЙОРК, 28 июля. /ТАСС/. Марсоход Perseverance ("Настойчивость") соберет в кратере Йезеро 40 образцов грунта, которые будут возвращены на Землю в 2031 году. Подробности этой операции сообщили во вторник эксперты на видеоконференции в Центре космических полетов имени Кеннеди.

"Вся операция состоит из трех элементов, которые будут тщательно синхронизированы, - сообщил эксперт NASA Джефф Грэмли. - Сначала марсоход Perseverance возьмет в титановые трубки пробы грунта и оставит их на поверхности. Эти пробы соберет другой марсоход, который будет запущен к Красной планете в 2026 году. На нем будет установлена возвращаемая ступень, куда будут загружены образцы, и она доставит их на орбиту к орбитальному модулю, а оттуда они будут направлены на Землю".

Как пояснила эксперт NASA Джулия Таунсенд, титановые трубки, которые Perseverance оставит на поверхности Марса, не потеряются даже в том случае, если они окажутся засыпанными во время песчаной бури. "Мы хорошо изучили район, где будет работать марсоход; и координаты точек, где будут оставлены собранные образцы, будут точно известны", - пояснила она.

Эксперт NASA Лайза Прэтт, занимающаяся вопросами обеспечения биологической безопасности при возвращении образцов марсианского грунта на Землю, отметила, что будут приняты все возможные меры для того, чтобы не занести на планету инопланетные микроорганизмы.

"Перед стартом марсоход Perseverance был тщательно обработан, чтобы не допустить попадания на Марс земных микроорганизмов, - сообщила она. - Особенно тщательно были обработаны трубки, куда будут собирать образцы: они на протяжении многих часов находились при температуре свыше 150 градусов Цельсия". По ее словам, собранные образцы грунта будут возвращены на Землю в тщательно изолированных титановых контейнерах, и их исследования будут проводиться в специальном центре, оборудованном максимальной биологической защитой.

Запуск ракеты-носителя с марсоходом Perseverance с космодрома на мысе Канаверал запланирован на 30 июля в 07:50 (14:50 мск). Собранные марсоходом образцы вернет на Землю специальная совместная миссия Европейского космического агентства (ЕКА) и NASA, которая будет отправлена к Марсу не раньше 2026 года.

With two days to go until NASA's Mars 2020 Perseverance rover blasts off on its seven-month journey to the Red Planet, everything is proceeding as planned.

On Tuesday, July 28, the rover made the one-third-mile trek from United Launch Alliance's (ULA) Vertical Integration Facility to Cape Canaveral Air Force Station's Space Launch Complex 41 in Florida. Now positioned at the pad, Perseverance is scheduled to launch aboard a United Launch Alliance Atlas V 541 rocket on Thursday, July 30. The two-hour window opens at 7:50 a.m. EDT. NASA's Launch Services Program, (LSP) based at Kennedy, is managing the launch.



Weather reports are positive. The U.S. Air Force 45th Weather Squadron is predicting an 80% chance of favorable weather conditions for the launch. The primary weather concerns are cumulus and thick clouds.
Several obstacles — including navigating a worldwide pandemic — have been overcome to keep the mission on schedule.

"COVID has placed a heck of a burden on us to get through this," Launch Director Omar Baez, LSP, said during Tuesday's NASA Edge Rollout show. "So it lives up to its name, Perseverance, and we're living it every day."
"It has been quite the learning experience for the whole program — and the agency," Baez continued. "But now, we're really excited."

Also Tuesday, NASA's Kennedy Space Center hosted a pair of live shows highlighting the importance and impact of Perseverance's mission: a Mars Sample Return briefing and a Mission Technology and Humans to Mars briefing. The rover will collect and store a set of rock and soil samples that could be returned to Earth by future Mars sample return missions.

"We're looking to accomplish one of the most complex things humanity has ever attempted," Mars Sample Return Program Director Jeff Gramling said. "With the launch of Perseverance will be the first step in a mission to bring back samples from another planet."

Developed under NASA's Mars Exploration Program, the rover will search for signs of past microbial life and help scientists better understand the geology and climate of Mars. Perseverance will reach Mars on Feb. 18, 2021, touching down on the surface of Jezero Crater. Lessons learned from the mission will pave the way for human exploration of the Red Planet.
