Scientists were able to capture ‘live’ footage of Mars for the the first time today.
The images were streamed to YouTube by the European Space Agency for a full hour.
Mars has only been previously seen in the past, through images from orbiters and landers exploring it, usually days after the shots were taken.
LIVE: FIRST MARS LIVESTREAM
The first-ever live image of Mars, sent to Earth with roughly a 16-minute delay. Images by the European Space Agency’s Mars Express (MEX) orbiter launched to the red planet in June 2003
The MEX orbiter, according to a representative from ESA, can only maintain the unusual position needed for this livestream ‘for about an hour.’ Such ‘real science data in real time,’ this ESA rep said during the livestream, is a ‘rare occurrence’ due to these challenges
ESA’s Mars exploration team answered questions during the livestream as the images came in
ESA scientist Jorge Vago, an ExoMars Project Scientist, told the livestream that the MEX satellite is passing by the dark side of Mars during Martian winter
But to celebrate the 20th birthday of ESA’s Mars Express (MEX) deep-space probe orbiting the Red Planet, experts spent weeks developing tools that would allow images from the probe’s camera to be streamed, live, for a full hour.
Around noon Eastern, 12pm ET (5pm UK time), new pictures were beamed down approximately every 50 seconds.
The Visual Monitoring Camera on Mars Express has previously discovered the evolution of a rare elongated cloud formation hovering above one of Mars’ most famous volcanoes – the 20 km-high Arsia Mons.
‘This is an old camera, originally planned for engineering purposes, at a distance of almost three million kilometres from Earth,’ said James Godfrey, Spacecraft Operations Manager at ESA’s Mission Control Centre in Darmstadt, Germany.
‘This hasn’t been tried before and to be honest, we’re not 100 percent certain it’ll work.
‘But I’m pretty optimistic. Normally, we see images from Mars and know that they were taken days before.
‘I’m excited to see Mars as it is now – as close to a martian ‘now’ as we can possibly get!’
Because of the vast distance between Earth and Mars – around 140 million miles on average – there was actually a slight delay in the transmission: a little over 16 minutes per image.
As past estimate from ESA said that the time between the images being taken from orbit around Mars and appearing on screen would be about 18 minutes.
ESA said: ‘That’s 17 minutes for light to travel from Mars to Earth in their current configuration, and about one minute to pass through the wires and servers on the ground.’
Mars is the fourth planet from the Sun – a dusty, cold, desert world with a thin atmosphere. For the first time, humanity saw Mars ‘live’ as images streamed almost in real time from the surface of the Red Planet, right on to YouTube. Pictured, Mars captured by the Hubble telescope
On Friday, to celebrate the 20th birthday of ESA’s Mars Express (depicted here), the viewing public had the chance to get as close as it’s currently possible get to Mars
There are only a few historical examples when humans on Earth have seen live images or video from space, including NASA’s DART mission that crashed a probe into a moonlet and the Apollo missions.
Mars Express, so called because of the rapid and streamlined development time, represents the European Space Agency’s (ESA’s) first visit to another planet in the solar system.
The spacecraft, launched in 2003, borrowed technology from ESA’s Rosetta and Mars 96 missions.
Since beginning science operations in 2004, the durable orbiter has given scientists an entirely new view of Earth’s intriguing neighbor.
It is now helping to answer fundamental questions about the geology, atmosphere, surface environment, history of water and potential for life on Mars.
Mars: The basics
Mars is the fourth planet from the sun, with a ‘near-dead’ dusty, cold, desert world with a very thin atmosphere.
Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.
It is one of the most explored planets in the solar system and the only planet humans have sent rovers to explore.

One day on Mars takes a little over 24 hours and a year is 687 Earth days.
