The drone, called Ingenuity, was airborne for less than a minute, but Nasa is celebrating what represents the first powered, controlled flight by an aircraft on another world.
Confirmation came via a satellite at Mars which relayed the chopper’s data back to Earth.
The space agency is promising more adventurous flights in the days ahead.
Ingenuity will be commanded to fly higher and further as engineers seek to test the limits of the technology.
The rotorcraft was carried to Mars in the belly of Nasa’s Perseverance Rover, which touched down in Jezero Crater on the Red Planet in February.
“We can now say that human beings have flown a rotorcraft on another planet,” said a delighted MiMi Aung, project manager for Ingenuity at Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

Ingenuity even carries a small swatch of fabric from one of the wings of Flyer 1, the aircraft that made that historic flight at Kitty Hawk, North Carolina, more than 117 years ago.

The demonstration saw the Mars-copter rise to about 3m, hover, swivel and then land. In all, it managed almost 40 seconds of flight, from take-off to landing.
Getting airborne on the Red Planet is not easy. The atmosphere is very thin, just 1% of the density here at Earth. This gives the blades on a rotorcraft very little to bite into to gain lift.
There’s help from the lower gravity at Mars, but still – it takes a lot of work to get up off the ground
Ingenuity was therefore made extremely light and given the power (a peak power of 350 watts) to turn those blades extremely fast – at over 2,500 revolutions per minute for this particular flight.
Control was autonomous. The distance to Mars – currently just under 300 million km – means radio signals take minutes to traverse the intervening space. Flying by joystick is simply out of the question.

Ingenuity has two cameras onboard. A black-and-white camera that points down to the ground, which is used for navigation, and a high-resolution colour camera that looks out to the horizon.
A sample navigation image sent back to Earth revealed the helicopter’s shadow on the floor of the crater as it came back in to land. Satellites will send home more pictures of the flight over the next day. There was only sufficient bandwidth in the orbiters’ first overflight to return a short snatch of video from Perseverance, which was watching and snapping away from a distance of 65m. Longer sequences should become available in due course.

Nasa has announced that the “airstrip” in Jezero where Perseverance dropped off Ingenuity for its demonstration will henceforth be known as the “Wright Brothers Field”.
The International Civil Aviation Organization (ICAO) – the United Nations’ civil aviation agency – has also presented the Nasa and the US Federal Aviation Administration with an official ICAO designator: IGY, call-sign INGENUITY.
A successful maiden outing means that a further four flights will be attempted over the coming days, each one taking the helicopter further afield.
In October 2018, Winamp relaunched a leaked version of the updated code as version 5.8. As a longtime winamp user, I was excited – I have many mp3’s which are not available on streaming services and also find that when I search for stuff on Spotify they give me the royalty free Filipino girl band cover version instead of the version I’m looking for.
I’ve been fairly happy with the 5.8 version but it did drop support for eg adding ID3 tags automatically and a few other things. Not being a huge user of the music library I don’t know how that went, but I was happy that they had Milkdrop visualiser support.
Today I came upon the following post on Reddit: Winamp visualizer ported in webgl, like back in the days. You can import your own songs in it. and in the comments found a project called WACUP. It turns out that one of the prolific plug in writers, who was also contracted to work in Winamp itself, DrO has been using the 5.666 version to build a huge slew of updates on and it’s still in development.
So, I’m uninstalling 5.8 and going to have a look at WACUP. I’m looking forward to continuing kicking the Llama’s ass!
A recent breach has prompted fears of another SolarWinds-style hack that could have ramifications for numerous large companies. Reutersreports that federal officials are investigating a hack at Codecov, a code testing firm with 29,000 customers that include Proctor & Gamble, the Washington Post and tech companies like Atlassian and GoDaddy. The intrusion appears to have lasted for months, putting clients at risk.
Codecov said that attackers exploited a flaw in a Docker image creation process to make “periodic, unauthorized” changes to the company’s Bash Uploader script starting on January 31st. The modifications gave the hackers power to export customer info and send it to an outside server. However, Codecov only learned of the incident on April 1st.
Our investigation has determined that beginning January 31, 2021, there were periodic, unauthorized alterations of our Bash Uploader script by a third party, which enabled them to potentially export information stored in our users’ continuous integration (CI) environments. This information was then sent to a third-party server outside of Codecov’s infrastructure.
