But Guy Webster, a spokesman for Mars exploration at NASA, told the Daily Beast that rumors about live humans on Mars are false.
"There are no humans on Mars," he said. "There are active rovers on Mars. There was a rumor going around last week that there weren't. There are, but there are no humans."
Jones is known for peddling elaborate and debunked conspiracy theories on his radio show, which airs on 118 stations around the country and reaches millions of listeners. The site had 4.5 million unique page views in the past month and more than 5 million from mid-April to mid-May, according to Quantcast. His YouTube channel has more than 2 million subscribers.
Among his most well-known accusations in recent years is that the December 2012 Sandy Hook massacre, in which 20 children and six adults were killed at a school in Newtown, Connecticut, was a hoax. Jones has claimed that the U.S. government orchestrated the Sept. 11, 2001, attacks and, more recently, promoted the "Pizzagate" conspiracy, which alleged that Hillary Clinton's presidential campaign was linked to a child-sex ring operating from the basement of a suburban Washington D.C. pizzeria.
The theory originated on Reddit, where a user claimed hacked emails belonging to Clinton campaign manager John Podesta revealed evidence of an international child-sex ring. The key, the user alleged, was replacing the word "pizza" with "little boy."
From that moment, the conspiracy theory took on a life of its own, culminating in a North Carolina man firing a military-style assault rifle inside the restaurant in December. Edgar Maddison Welch told investigators he was there to save abused children. Instead, he pleaded guilty to federal weapons charges in March and was sentenced to four years in prison last month.
Confronted about his Sandy Hook allegations during a controversial interview with NBC's Megyn Kelly last month, Jones hedged.
"I tend to believe that children probably did die there," he told the anchor. "But then you look at all the other evidence on the other side. I can see how other people believe that nobody died there."
On Thursday's Infowars broadcast, Steele appeared to connect the kidnapped children being held captive on Mars to pedophile rings who allegedly use children for their youthful body parts and energy.
"Pedophilia does not stop with sodomizing children," Steele said. "It goes straight into terrorizing them to adrenalize their blood and then murdering them. It also includes murdering them so that they can have their bone marrow harvested as well as body parts."
"This is the original growth hormone," Jones said.
"Yes, it's an anti-aging thing," Steele replied.
