The scientists expected to participate in the event – a couple of them, in particular – have some science fans believing they already know what NASA's big announcement will be. Among the speakers announced for the news conference is Lujendra Ojha, a graduate student at the Georgia Institute of Technology.

It's not all that common for a grad student to be on the panel for a NASA news conference, but some believe Ojha will be there to help the administration confirm his discovery of flowing salt water on Mars that he spotted in 2011 , according to CNN. Ojha made that discovery during his undergraduate studies at the University of Arizona , Inverse reported, along with his partner, Alfred McEwen.

McEwen is also expected to be part of the Monday news conference, NASA said in its release, adding to the speculation.

Some science-lovers expect big news from the Monday news conference, while others are taking a more wait-and-see approach.
