BELSPO, the Belgian federal science policy office, has created a virtual expo describing the long journey of NOMAD from first concept to current mission around Mars.

The expo is available in french by clicking here, or in dutch by clicking here.

ESA’s ExoMars Trace Gas Orbiter has detected glowing green oxygen in Mars’ atmosphere – the first time that this emission has been seen around a planet other than Earth. “One of the brightest emissions seen on Earth stems from night glow. More specifically, from oxygen atoms emitting a particular wavelength of light that has never been seen around another planet,” says Jean-Claude Gérard of the Université de Liège, Belgium, and lead author of the new study published in Nature Astronomy. “However, this emission has been predicted to exist at Mars for around 40 years – and, thanks to TGO, we’ve found it.”

In El Pais, the largest newspaper in Spain (and part of South America):

In June, NASA’s Curiosity rover reported the highest burst of methane recorded yet, but neither ESA’s Mars Express nor the ExoMars Trace Gas Orbiter recorded any signs of the illusive gas, despite flying over the same location at a similar time.

New press release from ESA:

Recently TGO passed the milestone of having observed Mars for a full Martian year, which is approximately the same length as two years here on Earth.


In this time:

  • LNO has recorded more than 2,000,000 nadir spectra of the surface and atmosphere of Mars
  • SO has recorded more than 15,000,000 spectra of the atmosphere of Mars

Today and tomorrow (12-13th September 2019) we are holding our next science working team meeting in Wroclaw, Poland. Here Hakan Svedhem is presenting the latest news from TGO and the upcoming 2020 Mars rover.
