Fly_across_Mars_s_labyrinth_of_night_wit Video: 00:03:44

Nestled between the colossal martian ‘Grand Canyon’ (Valles Marineris) and the tallest volcanoes in the Solar System (the Tharsis region) lies Noctis Labyrinthus – a vast system of deep and steep valleys that stretches out for around 1190 km (roughly the length of Italy here on Earth).

This video visualises a flight over the eastern part of Noctis Labyrinthus as seen by Mars Express’s High Resolution Stereo Camera (HRSC). It presents a perspective view down and across this fascinating landscape, showing distinctive ‘graben’ – parts of the crust that have subsided in relation to their surroundings. The intense volcanism in the nearby Tharsis region is to blame for the formation of these features; this volcanism caused large areas of martian crust to arch upwards and become stretched and tectonically stressed, leading to it thinning out, faulting and subsiding.

The highest plateaus seen here represent the original surface level before chunks of surface fell away. The intersecting canyons and valleys are up to 30 km wide and six km deep. In many places, gigantic landslides can be seen covering the valley slopes and floors, while other valley slopes show large dune fields created by sands blown both down and upslope by martian winds.

ESA has highlighted Mars Express images of Noctis Labyrinthus before, in 2006 and 2015. Mars Express has orbited the Red Planet since 2003, imaging Mars’s surface, mapping its minerals, studying its tenuous atmosphere, probing beneath its crust, and exploring how various phenomena interact in the martian environment. For more from the mission and HRSC, see ESA's Mars Express releases.

Processing notes: The video was created using an image mosaic built over eight orbits (0442, 1085, 1944, 1977, 1988, 10497, 14632 and 16684) by ESA’s Mars Express and its HRSC. This mosaic is combined with topographic information from a digital terrain model to generate a three-dimensional landscape, with every second of the video comprising 50 separate frames rendered according to a pre-defined camera path. The opening credits (Mars globe, first 24 seconds) were created using the recent 20-year Mars global colour mosaic; this opening sequence has a three-fold vertical exaggeration, while the subsequent flight animation has a 1.5-fold exaggeration. Haze has been added to conceal the limits of the terrain model, and starts building up at distance of between 150 and 200 km. The video is centred at the martian coordinates of 7°S, 265°E.

Alt-text: The video begins on a rotating full-globe of Mars, with white polar caps and mottled tan surface visible. It then zooms in on the westernmost part of the large Valles Marineris canyon system, a region highlighted by a white box, and swaps to a new Mars Express visualisation of Noctis Labyrinthus. The camera then flies slowly across a landscape that is broken apart by deep intersecting valleys and canyons.

      Video: 01:08:00 Watch the replay of our Hera mission Mars flyby event. On 12 March 2025, ESA’s Hera mission came to within 5000 km of the surface of the red planet and 300 km of Mars’s more distant and enigmatic moon Deimos. During this flyby, Hera performed observations of both Mars and the city-sized Deimos. Hera then needed to swing its High Gain Antenna back to Earth to transmit its data home. On Thursday, 13 March, these images were premiered by Hera’s science team from ESA’s ESOC mission control centre in Darmstadt, Germany, explaining what they reveal, during our public webcast starting at 11:50 CET. The team was joined by ESA astronaut Alexander Gerst and renowned science fiction writer Andy Weir, author of The Martian and Project Hail Mary, as well as a surprise special guest!

      While performing yesterday’s flyby of Mars, ESA’s Hera mission for planetary defence made the first use of its payload for scientific purposes beyond Earth and the Moon. Activating a trio of instruments, Hera imaged the surface of the red planet as well as the face of Deimos, the smaller and more mysterious of Mars’s two moons.

      On March 26, 2020, a French astronomer Mark Carlotto used a telescope to capture a video showing the moon at night. Dr. M. Carlotto is a specialist in digital video analysis of space objects. The video shows three objects rising above the Moon’s limb, flying across the lunar surface and disappearing in the Moon’s shadow. 

      The fact that some of these objects are so clearly visible and close enough to the moon to be able to cast noticeable shadows immediately suggests that they are quite large. Using the large Endymion crater as a benchmark, the sizes of the objects were determined. 

      The size of the object flying over Endymion is about 5 miles long and about 1 to 3 miles wide. The other two objects appear to be comparable in size. 
      By measuring the displacement of the object it appears that the object is traveling at about 31 mps. It is traveling more than 30 times faster than if it were in lunar orbit. 

      A paper was recently published that attempts to prove that the original video is a fake. Arxiv.org analyzed the video (not included in the analysis) but extracted and provided three images of the recorded objects for examination, as seen above, and they then conducted calculations to verify its authenticity. 
      Despite government and space agency denials of UFO existence, photographic evidence and subsequent analysis suggest the presence of large extraterrestrial craft near the Moon and elsewhere in space.View the full article

      Video: 00:02:43 On 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel.
      This is a simulation of that flyby, sped up 500 times, with closest approach to Martian moon Deimos taking place at 12:07 GMT and Mars occurring at 12:51 GMT. It was made using SPICE (Spacecraft, Planet, Instrument, C-matrix, Events) software. Produced by a team at ESA’s ESAC European Space Astronomy Centre, this SPICE visualisation is used to plan instrument acquisitions during Hera’s flyby.
      Hera comes to around 5000 km from the surface of Mars during its flyby. It will also image Deimos, the smaller of Mars’s two moons, from a minimum 1000 km away (while venturing as close as 300 km). Hera will also image Mars’s larger moon Phobos as it begins to move away from Mars. In this sped-up simulation, Deimos is seen 30 seconds in, at 12:07 GMT, while the more distant star-like Phobos becomes visible at two minutes in, at 12:49 GMT.
      The spacecraft employs three of its instruments over the course of these close encounters, all located together on the ‘Asteroid Deck’ on top of Hera:
      Hera’s Asteroid Framing Camera is formed of two redundant 1020x1020 pixel monochromatic visible light cameras, used for both navigation and science.
      The Thermal Infrared Imager, supplied by the Japanese Aerospace Exploration Agency, JAXA, images at mid-infrared wavelengths to determine surface temperatures.
      Hera’s Hyperscout H is a hyperspectral imager, observing in 25 visible and near-infrared spectral bands to prospect surface minerals.

      Video: 00:01:36 On  Wednesday 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards its final destination of the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel.
      Watch the livestream release of images from Hera’s flyby by the mission’s science team on Thursday 13 March, starting at 11:50 CET!
      Hera comes to around 5000 km from the surface of Mars during its flyby. It will also image Deimos, the smaller of Mars’s two moons, from a minimum 1000 km away (while venturing as close as 300 km). Hera will also image Mars’s larger moon Phobos as it begins to move away from Mars.
      Launched on 7 October 2024, Hera on its way to visit the first asteroid to have had its orbit altered by human action. By gathering close-up data about the Dimorphos asteroid, which was impacted by NASA’s DART spacecraft in 2022, Hera will help turn asteroid deflection into a well understood and potentially repeatable technique.
      Hera will reach the Didymos asteroid and its Dimorphos moonlet in December 2026. By gathering crucial missing data during its close-up crash scene investigation, Hera will turn the kinetic impact method of asteroid deflection into a well understood technique that could potentially be used for real when needed.
