NASA is returning to sizzling Venus, our closest yet perhaps most overlooked neighbor, after decades of exploring other worlds.
The space agency's new administrator, Bill Nelson, announced two new robotic missions to the solar system's hottest planet, during his first major address to employees Wednesday.
“These two sister missions both aim to understand how Venus became an inferno-like world capable of melting lead at the surface," Nelson said.
One mission named DaVinci Plus will analyze the thick, cloudy Venusian atmosphere in an attempt to determine whether the inferno planet ever had an ocean and was possibly habitable. A small craft will plunge through the atmosphere to measure the gases.
It will be the first U.S.-led mission to the Venusian atmosphere since 1978.
The other mission, called Veritas, will seek a geologic history by mapping the rocky planet’s surface.
“It is astounding how little we know about Venus," but the new missions will give fresh views of the planet's atmosphere, made up mostly of carbon dioxide, down to the core, NASA scientist Tom Wagner said in a statement. “It will be as if we have rediscovered the planet.”
NASA’s top science official, Thomas Zurbuchen, calls it “a new decade of Venus.” Each mission — launching sometime around 2028 to 2030 — will receive $500 million for development under NASA’s Discovery program.
The missions beat out two other proposed projects, to Jupiter's moon Io and Neptune's icy moon Triton.
The U.S. and the former Soviet Union sent multiple spacecraft to Venus in the early days of space exploration. NASA's Mariner 2 performed the first successful flyby in 1962, and the Soviets' Venera 7 made the first successful landing in 1970.
In 1989, NASA used a space shuttle to send its Magellan spacecraft into orbit around Venus.
The European Space Agency put a spacecraft around Venus in 2006.

In 2015, 193 parties signed the Paris Agreement. In doing so, they agreed to pursue efforts to limit the average global temperature increase to 1.5° Celsius - or 2.7 degrees Fahrenheit -above pre-industrial levels. To be clear, our planet is already 1.1 degrees hotter than it was 150 years ago. But most scientists agree that an increase of just .4 more degrees will drastically change the world. However, it would continue to be livable. Things do get murky, though, as the projections increase above that.
Dr. Jen Caudle, family physician and associate professor at Rowan University, joined Cheddar to break down how people can protect themselves and family amid the uncertainty of the new Omicron COVID-19 variant. Caudle emphasized the importance of getting vaccinated against COVID-19 with so much still uncertain about the pandemic. "We have to remember delta variant is still here in the United States," she said. "We're still losing too many people every single day to this virus."
Jill and Carlo discuss what appears to be the beginning of the end of Roe v. Wade, another victim dies following the school shooting in Michigan, Omicron in the U.S., Trump's Covid chronology and more.
Was it a coincidence that the omicron coronavirus variant evolved in a region with low vaccination rates? Cheddar speaks with epidemiologist Dr. Eric Feigl-Ding on the topic.
Astra founder, chairman, and CEO Chris Kemp spoke to Cheddar's Kristen Scholer about his company's first successful launch into orbit last month, becoming the fastest space company to reach orbit using a privately developed liquid-fueled rocket. He also noted that the company's priority is to "improve life on Earth from space" by rapidly increasing the number of low-orbiting satellites to do everything from connecting people to monitoring weather patterns.
Stocks closed at session lows Wednesday as investors grew skittish over the first reported case of the COVID-19 omicron variant in California. Josh Sailar, Partner at Blue Zone Wealth Advisors, joins Cheddar News' Closing Bell to discuss investor worry over the new variant, the Fed dropping the word 'transitory' to describe inflation and potentially speeding up their asset tapering timeline, 2022 predictions, and more.
As cases of the COVID-19 Omicron variant continue to pop up, including the first U.S. case in California, how will domestic holiday travel be impacted? That part of the travel sector has mostly recovered from the year-long pandemic rout, while business travel continues its slump. But could a new variant bring new lockdowns and domestic restrictions? Clint Henderson, Senior News Editor at The Points Guy, joins Cheddar News' Closing Bell to discuss what the omicron variant means for holiday travel, best practices for passengers traveling through airports, and more.
Over the Thanksgiving holiday, Elon Musk warned SpaceX employees in a leaked email that the company could be forced to file Chapter 11 bankruptcy if its raptor engine program fails. Musk then commented on the previous statement adding the detail that a recession could make such a bankruptcy possible.
