NASA's computer systems were anonymously attacked by a team of hackers as part of a global campaign against government cover-ups.
New World Hacking and AnonCorrupt attacked the agency on Sunday night and have claimed to have "blasted" the space agency's main website using a cyber-attack known as a Ddos attack.
According to reports, the NASA website does not appear to have been brought down and is still in action, the hackers presented us with evidence that suggests some of its systems are still suffering from the after-effects of a digital blitzkreig.
The hackers alleged NASA to be covering-up a piece of key information about the terror group ISIS, although it refused to disclose what this secret actually is.
In the past, New World Hacking took responsibility for an "apocalyptic" attack on the BBC taking them down for a few hours on New Year’s Eve .
The attacked has not yet been confirmed nor denied by NASA which has been claimed to occur late Sunday evening, and it is not yet possible to verify the hacktivists' claims.
"We believe NASA is holding back information on many things, not just one," a member of New World Hacking told Mirror.co.uk.
"The main thing we suspect they are holding back some more information on ISIS that the public needs to know.
"We won't tell the public what we think they are hiding - we will let NASA explain."
The group said the attack was part of a campaign called Operation Censorship (or #OPCensorship) and was also a practice run for upcoming cyber-assaults against Donald Trump, which are expected to take place on April Fool's Day.
"This attack is a protest and a demonstration," it continued.
"We want Trump to know that he is next."
The New World Hackers said NASA's email servers were brought down during the hack attacks, which were launched by a number of supporters around the world.
