NASA's Perseverance (Mars 2020) rover will store rock and soil samples in sealed tubes on the planet's surface for future missions to retrieve in the area known as Jezero crater on the planet Mars. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, paving the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

NASA's first-ever Mars helicopter is preparing to take to the Martian skies following Thursday's successful Perseverance rover landing in the planet's Jezero Crater.

Ingenuity is currently attached to the rover's belly and its mission is also historic: the 4-pound helicopter will attempt the first powered-controlled flight on another planet.

However, in order to successfully do so, Perseverance will have to take additional steps

to prepare before it can embark on the hunt for a safe takeoff site.

Over the next month or two, engineers will test the rover's systems and instruments before the flight test phase can begin.

NASA announced Friday that they had received their first status report from the helicopter, indicating it is operating as expected.

On Saturday, the team will move to power up its six lithium-ion batteries to about 30% of its total capacity and incrementally increase charge from the rover's power supply on a weekly basis.

After Perseverance releases Ingenuity onto the surface, the helicopter will be charged solely by its own solar panel.

Ingenuity has a month-long window for up to five test flights, but it won't be an easy process.

Mars has nights with temperatures as cold as minus 130 degrees Fahrenheit and the planet has a rarefied atmosphere that's just about 1% of the density of Earth's atmosphere -- though the planet's gravity could give the helicopter a boost.

Once Perseverance locates a site to deploy Ingenuity, the rover’s Mars Helicopter Delivery System will shed the landing cover and gently drop it.

"Percy" will also help NASA communicate with Ingenuity -- which will make a lot of its own decisions because of interplanetary communication delays -- using programmed parameters set by engineers.

For example, Ingenuity has a thermostat to help it keep warm, as well as the ability to analyse and sensor data and images of the planet's terrain, like Perseverance's Terrain Relative Navigation.

According to NASA, a victorious maiden takeoff and hover would meet 90% of the team's project goals.

"We are in uncharted territory, but this team is used to that," said Jet Propulsion Laboratory Ingenuity Project Manager MiMi Aung. "Just about every milestone from here through the end of our flight demonstration program will be a first, and each has to succeed for us to go on to the next. We’ll enjoy this good news for the moment, but then we have to get back to work."
