NASA will lift the veil on its new discoveries later today at 7pm BST (2pm EDT) during a live press conference.
Ahead of the announcement this evening, NASA teased it will share “two new Mars science results from the Mars Curiosity rover”.
Specific details concerning the discoveries are under embargo until 7pm but a few minor conference details could contain crucial clues NASA has found signs of alien life.
Some of NASA’s most prominent scientists are scheduled to make an appearance in just a few hours and the clues could be in their individual areas of expertise.
One of the space boffins is NASA’s Jennifer Eigenbrode, a biogeochemist and geologist, specialising in astrobiology.
Last year she said in an interview: “I look at organic molecules in rocks, ice and sediments and try to figure out where they came from and what happened to them over time.
“I want to know their story. Are they from life?”
Nick Pope, a former British Ministry of Defence man who investigated the UFO phenomenon for the department until 2009, said Dr Eigenbrode’s background is very “suggestive”.
Mr Pope tweeted: “Has NASA found life on Mars?
“The media advisory on Thursday’s press conference on ‘new science results’ from Curiosity rover states that results are embargoed by Science magazine and Eigenbrode’s bio is suggestive.
“Watch this space – pun intended.”
He later added: “I predict the NASA press conference today will cover whether organic molecules on Mars come from biological or non-biological sources.
“So we may get discussion of ‘the building blocks of life’, but we won’t get ‘We’ve found aliens!’”
The other panellists are all similarly involved in Martian geologic studies and planetary atmospherics.
The acclaimed members of the panel are Paul Mahaffy, director of the Solar System Exploration Division at NASA’s Goddard Space Flight Center, Chris Webster, from NASA’s Pasadena-based Jet Propulsion Laboratory (JPL) and Ashwin Vasavada, Mars Science Laboratory project scientist.
Dr Webster is another NASA astronomer whose research interests include Mars’ chemistry and habitability.
Over the years, Dr Webster has published a number of papers on the detection of methane on Mars – ages which is created by microbes back on Earth.
The exciting press conference will broadcast live over the internet – you can watch it here online on Express.co.uk.
The NASA event will also broadcast on NASA Television, Facebook Live, Ustream, Periscope and Twitch TV.
