CAPE CANAVERAL AIR FORCE STATION/KENNEDY SPACE CENTER, FL – Its been a busy start for NASA’s $2.7 Mars 2020 Perseverance rover mission to the Red Planet with a duo of major activities accomplished since blasting off from the Florida Space Coast on July 30.

One week into its seven-month interplanetary journey to Mars NASA’s Ingenuity Mars Helicopter recharged its batteries for the first time on Friday, Aug. 7 and the Perseverance cruise stage spacecraft completed her first major course correction after two weeks on Friday, Aug. 14.

Ingenuity, a twin-rotor, solar-powered helicopter attached to the belly of the rover, will become the first aircraft to fly on another world.

“This was a big milestone, as it was our first opportunity to turn on Ingenuity and give its electronics a ‘test drive’ since we launched on July 30,” said Tim Canham, the operations lead for Mars Helicopter at NASA’s Jet Propulsion Laboratory in Southern California, in a statement.

“Since everything went by the book, we’ll perform the same activity about every two weeks to maintain an acceptable state of charge.”

The Aug. 7 operation marked the first time the helicopter was powered up and its batteries charged in the space environment.

During the eight-hour operation, the performance of the rotorcraft’s six lithium-ion batteries was analyzed as the team brought their charge level up to 35%. The project has determined a low charge state is optimal for battery health during the cruise to Mars,” said NASA.

The Trajectory Correction Maneuver known as TCM-1 was the first of six TCM’s planned during the 300 million mile (500 million km) interplanetary journey to Mars after launching atop a powerful United Launch Alliance Atlas V rocket on July 30.

The TCMs involve thruster firings on the solar powered cruise stage to refine the Mars 2020 flight path to the Red Planet.

The ensure the spacecraft hits exactly the right spot in the Martian atmosphere to begin the do-or-die Entry Descent and Landing (EDL)  phase known as the ‘7 minutes of Terror.’

“My first planned Trajectory Correction Maneuver was a success. I do TCMs on my journey to stay on target for a Feb. 18, 2021 date with Mars. I left Earth over 2 weeks ago and already put on 27+ million miles. Only ~265 million more to go! #CountdownToMars ,” Perseverance tweeted from 27 million miles away!

Perseverance is scheduled to touch down in an area of Mars known as Jezero Crater on Feb. 18, 2021.

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.

The solar powered Ingenuity helicopter is a technology demonstration experiment aimed at attempting the first flight on Mars.

It is stowed on the belly and receives its charge from the rover’s power supply.

The four legged Ingenuity has a mass of about 4.0 pounds (1.8  kilograms) and stands 1.6 feet or 19 inches (0.49 meters) high. It is equipped with two counter rotating blades for lift spinning at about 2,400 rpm and two cameras.

After Ingenuity is deployed on Mars’ surface its batteries will be charged solely by the helicopter’s own solar panel. If Ingenuity survives the cold Martian nights during its preflight checkout, the team will proceed with testing.

“This charge activity shows we have survived launch and that so far we can handle the harsh environment of interplanetary space,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at JPL, in a statement.

“We have a lot more firsts to go before we can attempt the first experimental flight test on another planet, but right now we are all feeling very good about the future.”

“The small craft will have a 30-Martian-day (31-Earth-day) experimental flight-test window. If it succeeds, Ingenuity will prove that powered, controlled flight by an aircraft can be achieved at Mars, enabling future Mars missions to potentially add an aerial dimension to their explorations with second-generation rotorcraft.”
