Cape Canaveral (AFP) – NASA on Monday began the countdown to the launch of a new Mars spacecraft on a mission to study how the air on the Red Planet has changed over time.

Researchers have described the mission as a search for a missing piece to the puzzle of what happened to Mars’ atmosphere, perhaps billions of years ago, to transform Earth’s neighbor from a water-bearing planet that might have been favorable for life to a dry, barren desert.

The launch of the unmanned Mars Atmosphere and Volatile EvolutioN (MAVEN), could happen as early as 1:28 pm from Cape Canaveral, Florida.

Despite some concerns about thick clouds, the weather forecast was 60 percent favorable for takeoff during a two-hour launch window, U.S. Air Force officials said Monday.

After a 10-month journey to Mars, the orbiter will take measurements at various altitudes to help scientists learn about the atmosphere, which has never been studied before.

“MAVEN is the first spacecraft devoted to exploring and understanding the Martian upper atmosphere,” the U.S. space agency said. “The spacecraft will investigate how the loss of Mars’ atmosphere to space determined the history of water on the surface.”

NASA has sent a series of rovers to explore the surface of the Red Planet, including its latest, Curiosity, which arrived last year.

The deep space orbiter launched earlier this month by India seeks to find traces of methane from Mars and may arrive two days later than the U.S. spacecraft, if NASA’s launch goes ahead as planned on Monday.

The science goals of the two do not overlap much. The Indian probe will be searching for methane which could prove the existence of some ancient life form, while the U.S. probe seeks answers about the planet’s climate change.

The entire MAVEN mission cost $671 million.

The eight-foot (2.5 meter) cube-shaped spacecraft weighs 5,410 pounds and is posed to launch aboard an Atlas V 401 rocket from Cape Canaveral Air Force Station.

Arrival at Mars is scheduled for September 2014 and the science mission of the solar-wing paneled orbiter is set to begin in November 2014.

Much of its year-long mission will be spent circling the planet at a distance of 3,800 miles above the surface, but it will execute five deep dips to a height of just 78 miles to get readings of the atmosphere at various levels.

By measuring the current rate of escape to space and gathering information about how the atmosphere is thinning, scientists hope to be able to extrapolate back in time and estimate when it started and how it happened.

MAVEN’s findings are expected to help pave the way for a future visit by humans to the Red Planet, perhaps as early as the 2030, NASA has said.

On Tuesday, the House Select Committee hearing featured testimony from Cassidy Hutchinson, former Trump Chief of Staff Mark Meadows’ aide. It was damning. Hutchinson went on the record reiterating what she had told investigators previously, detailing the many things she saw and heard before and during January 6, 2021. Her testimony touched on Trump’s insistence that he join the riot at the Capitol, his knowledge of armed MAGA audience members, the bizarre disappearing act Meadows performed, and the fact that leading up to the “Stop the Steal” rally, Trump’s own lawyer knew that crimes were most likely being committed.

One of the more explosive moments in Hutchinson’s testimony concerned her recounting of what Trump’s former lead Secret Service agent turned political adviser Anthony Ornato told her about Donald Trump’s actions, alleging he attacked his chief security official, Robert “Bobby” Engel, when Engel would not allow him to lead the rioters at the Capitol grounds. This reportedly took place after Trump left the Stop of Steal rally on January 6, 2021.

Wayne Willott, a QAnon influencer known online as “Juan O. Savin” who is recruiting and supporting candidates for election-administration positions around the country, warned of “civil war” if people try to “move past” the 2020 presidential election.

Savin is part of a coalition led by Jim Marchant, which aims to recruit and elect secretary of state candidates who have pushed false claims of widespread voter fraud in the 2020 presidential election.
