In this method, theres actually no such thing as live news in space as we are restricted by the speed of light passing through excellent distances.

On Friday, to celebrate the 20th birthday of ESAs Mars Express, youll have the possibility to get as close as its presently possible get to Mars. Tune in to be among the very first to see new images roughly every 50 seconds as theyre beamed down directly from the Visual Monitoring Camera (VMC) on board ESAs long-lived but-still-highly-productive Martian orbiter.
Get live updates through @esaoperations on Twitter and with the hashtag #MarsLIVE. Livestream starts 9:00 a.m. PDT (12:00 p.m. EDT, 18:00 CEST, 17:00 BST).

Live on Mars
A lot of information and observations gathered by spacecraft are taken during periods when they are not in direct contact with a ground station antenna on Earth. Either since of geometry– for instance, on the other side of the Sun or Mars– or the spacecrafts antenna is pointing away from Earth while collecting science data.
For science, this is no problem. The information is saved on board and beamed down a few hours or even days later on, once the spacecraft is in contact with the ground again. What generally takes place for the Visual Monitoring Camera on Mars Express, is every couple of days a brand-new batch are downlinked, processed, and offered to the world.
The speed of light. Frustrating? Sometimes. It also allows for objectives like Euclid, which will catch light thats been taking a trip for 10 billion years, allowing us to see 10 billion years into the past.

For the majority of area missions, this works completely. Researchers then pore over the data that come in for years, finding new tricks about the Universe. This makes live footage rather unusual.
In truth, there are just a couple of examples in the history of spaceflight; including NASAs DART and LCROSS objectives which filmed the deem they intentionally crashed into asteroid Dimorphos and the Moon, respectively, and of course, the Apollo missions returned amazing live video that captured the globe, revealing astronauts strolling on the Moons surface area.
These missions were all quite near to home and others further away sent out possibly an image or 2 in near real-time. When it comes to a lengthy livestream from deep area, this is an initially.

During Fridays one-hour livestream, the time between the images being drawn from orbit around Mars and appearing on your screen will be about 18 minutes. Thats 17 minutes for light to travel from Mars to Earth in their current setup, and about one minute to travel through the wires and servers on the ground.
Keep in mind, weve never ever attempted anything like this before, so specific travel times for signals on the ground remain a little unpredictable.

It wasnt supposed to be like this.
Mars Expresss Visual Monitoring Camera, dubbed the Mars Webcam, was not prepared for such record breaking. Its main job, 20 years ago, was to monitor the separation of the Beagle 2 lander from the MEX spacecraft. Once it had actually done that, and reported back, it was turned off.
A bit like the monitoring electronic cameras on board ESAs Juice spacecraft, which send back visuals of instruments and solar selections being released, it wasnt implied to be a science instrument and it didnt need to take specifically precise images. And yet, here we are.
The bright spot on the left-hand side of this picture is the rear end of Beagle 2, gradually drifting away from Mars Express. This image, taken at 9:33 CET, December 19, 2003, (about 1min:03 secs after separation), shows the lander when it had to do with 20 meters away from the Mars Express orbiter, on its way to Mars.

In 2007, the VMC was turned back on and used for science and outreach activities, consisting of campaigns to encourage space lovers and schools to propose observations of Mars. It got its own Flickr page and the Mars Webcam was born (note: the Twitter account has actually now moved to Mastodon). Just later, researchers understood that these images might be used for proper science.

” We established new, more advanced approaches of operations and image processing, to get better arise from the video camera, turning it into Mars Expresss 8th science instrument,” describes Jorge Hernández Bernal, part of the VMC group.
” From these images, we found a lot, including the advancement of an uncommon extended cloud development hovering above one of Mars most well-known volcanoes– the 20 km-high Arsia Mons.”.
Although it looks like if a plume of smoke is increasing out of the volcano, the function remained in truth climatic in nature.
The group discovered that this cloud kinds when extremely quick winds blow versus the top of the volcano, causing a really strong wave that presses upwards, cooling the atmosphere by 30ºC, causing water ice condensation and clouds forming. How this cloud becomes extended out and lengthened, remains a secret.
In event of the productive and long life of Mars Express, groups have invested the last couple of months developing tools that would enable for the higher-quality, science-processed images to be streamed, live, for a complete hour.
” This is an old electronic camera, originally prepared for engineering purposes, at a distance of practically 3 million kilometers from Earth– this hasnt been tried before and to be honest, were not 100% certain itll work,” describes James Godfrey, Spacecraft Operations Manager at ESAs mission control center in Darmstadt, Germany.

” But Im pretty optimistic. Typically, we see images from Mars and know that they were taken days before. Im excited to see Mars as it is now– as near to a Martian now as we can perhaps get!.
Join ESA for the #MarsLIVE stream on June 2 on the ESA Youtube channel, from 9:00 a.m. PDT (12:00 p.m. EDT, 18:00 CEST, 17:00 BST), as we wish a delighted 20th birthday to Mars Express.

The European Space Agency (ESA) is hosting a one-hour Mars livestream on June 2, 2023, for the 20th anniversary of Mars Express. Direct images from Mars will be broadcast approximately every 50 seconds through the Visual Monitoring Camera, marking a first in area livestreaming. In spite of an 18-minute delay due to light travel and signal processing, this effort will bring Mars to Earth in as near to real-time as presently possible.
For one hour on Friday, June 2, 2023, join ESA on YouTube for an area initially as live images stream down direct from Mars– this will be the closest you can get to a live view from the Red Planet.
Does Mars really exist? Yes, however we just have evidence of it as it remained in the past, once light has actually bounced off it or is sent out by landers and orbiters exploring it, and takes a trip to Earth. Depending upon the two worlds relative positions in orbit around the Sun, this can take anywhere from 3 to 22 minutes.
