WASHINGTON (Reuters) - NASA is considering approving by next April up to two planetary science missions from four proposals under review, including one to Venus that scientists involved in the project said could help determine whether or not that planet harbors life.
An international research team on Monday described evidence of potential microbes residing in the harshly acidic Venusian clouds: traces of phosphine, a gas that on Earth is produced by bacteria inhabiting oxygen-free environments.It provided strong potential evidence of life beyond Earth.
The U.S. space agency in February shortlisted four proposed missions that are now being reviewed by a NASA panel, two of which would involve robotic probes to Venus. One of those, called DAVINCI+, would send a probe into the Venusian atmosphere.
"Davinci is the logical one to choose if you're motivated in part by wanting to follow this up - because the way to follow this up is to actually go there and see what's going on in the atmosphere," David Grinspoon, an astrobiologist working on the DAVINCI+ proposal, told Reuters on Tuesday.
The three other proposals include: IVO, a mission to Jupiter's volcanically active moon Io; Trident, a fly-by trek to map Neptune's icy moon Triton; and VERITAS, the second of the proposed Venus missions that instead would focus on understanding the planet's geological history. NASA has said it may choose one or two of the missions.
The search for life elsewhere in the solar system has until now not focused on Venus. In fact, NASA in July launched a next-generation rover to look for traces of potential past life on Mars.
In light of Monday's findings, NASA Administrator Jim Bridenstine said that is "time to prioritize Venus." In a statement, Bridenstine said the selection process for the new potential missions will be tough "but I know the process will be fair and unbiased."
Grinspoon, a senior scientist at the Planetary Science Institute, said the selection process should be responsive to recent scientific discoveries.
"If there was a mission to Triton as a finalist, and then somebody with a telescope observed, you know, a soccer stadium on Triton, then arguably yeah, we should send a mission there," Grinspoon said.

Maine Blueberry Industry Reels From Drought, Frost, Virus
By PATRICK WHITTLE, Associated Press
PORTLAND, Maine (AP) — A late spring frost, a devastating drought and labor troubles wrought by the coronavirus pandemic conspired to make 2020 a difficult year for the wild blueberry producers who harvest the fruit in the nation's northeastern corner.
America's producers of wild blueberries are largely located in Maine, where the blueberry industry has battled fungal plant diseases and erratic market conditions in recent years. The harvest takes place every summer, and this year's crop was likely far off last year's total of about 87 million pounds, industry experts said.
One of the biggest problems was the drought, which afflicted much of northern New England throughout the summer. The rural Maine counties that contain most of the country's wild blueberry fields are even now facing moderate drought conditions, according to the U.S. Drought Monitor.
The pandemic also made it more difficult to hire seasonal workers and created a need for additional safety measures that complicated the harvest. Add a surprise frost in early June, and it added up to “most definitely a challenging season,” said Lily Calderwood. a wild blueberry specialist at University of Maine Cooperative Extension.
“It was uniquely challenging, but we have had late frosts in the past and we have had drought in the past," she said. "The growers are a very resilient group of farmers who grow a very diverse crop.”
Wild blueberries differ from the ubiquitous cultivated blueberries in that they are smaller and occur naturally in fields called blueberry barrens. Maine's blueberry industry has touted the wild blueberries as a potential piece of the “superfood” movement in recent years. Most of the crop is frozen, though some are sold in Maine farm stands and supermarkets every August.
The five-year average for the size of the crop is nearly 84 million pounds, but signs point to a crop that could be half of expectations this year, according to the Wild Blueberry Commission of Maine. However, demand for the fruit has increased recently, and the industry has the ability to bounce back from the tough year, said Eric Venturini, the executive director of the blueberry commission.
“Despite the down year in terms of production, demand is high," he said. "I think leveraging that will definitely be part of the game plan.”
Maine competes with Canada in the wild blueberry market, and some companies operate on both sides of the border. The uneven exchange rate with Canada has caused economic problems for Maine's industry in recent years. Still, prices to farmers have rebounded in recent seasons after down years in 2016 and 2017.
This year, some blueberry workers tested positive for coronavirus, and companies responded by keeping them in quarantine. Workers were tested before they began work to prevent potential outbreaks.
It was a frustrating year in the fields, but the industry was able to prevent spreading coronavirus to surrounding communities in Washington County, where many fields are located, said Homer Woodward, vice president of operations for Wyman's, one of the major players in the industry.
“The size of the crop was disappointing but as far as navigating COVID, as far as preventing it from becoming a problem in Washington County, I think that was a success for the industry,” Woodward said.
