The headline query sounds hyperbolic. Let’s put it in context.

Since life started on earth about 4.5 billion years in the past, nearly all the pieces — from temperatures to land plenty to the types of life that exist right here — has modified and developed. Besides gravity.
“Gravity is fixed on earth, and all life on earth is structured round gravity,” says Nicolas Gaume, CEO and co-founder of Area Cargo Limitless, the startup main an utilized analysis program in area that, in 2020, despatched 12 bottles of Pétrus Millésime 2000 and 320 rising vines of Merlot and Cabernet Sauvignon to the Worldwide Area Station (ISS). “The whole lot right down to the mobile construction of vegetation and animals is optimized for gravity. Whenever you take away gravity, you add a stress that’s immense.”
Mission WISE
The wine and area undertaking, dubbed Mission WISE, despatched the bottles and vines to the ISS for 438 days and 19 hours. On January 14, 2021, they returned to earth after a journey of 300 million kilometers in zero gravity. The replanting of the area vines happened in February 2022.
Now, the Area Cargo crew is revealing preliminary findings produced in collaboration with researchers on the Institut Francais de la Vigne ed du Vin in Bordeaux and at FAU Erlanger-Nuremberg Univeristy. After finding out these viticultural area cadets, in comparison with “twin” vines and bottles of wines grown and saved beneath regular situations on Earth, they’ve discovered notable variations.
“We hoped to provoke a self-guided evolution within the vines by eradicating gravity,” Gaume explains. “Because the Nineteen Fifties, we have now had the know-how to review the impact of chosen situations of area on terrestrial life. We thought that by exposing the vegetation to the largest stress they’ll expertise, the absence of gravity, they might return to Earth extra resistant, and capable of stand as much as different stressors, like local weather change.”
Stronger vines
The preliminary findings are thrilling and bode nicely for natural agriculture normally, Gaume says.
Whereas he stresses that extra exams wanted to be carried out, and he declines to share particular information factors, he says it’s clear that eradicating gravity has an outsized influence on a number of key areas of concern.
“Local weather change has elevated the incidence of downy mildew and phylloxera in grapes the world over. As a result of these issues are so prevalent, we centered on them initially,” he says. Certainly, in a analysis paper printed in 2020, the Area Cargo crew famous that manufacturing prices have skyrocketed as much as 50 % as growers battle to take care of the unfold of downy mildew within the wake of local weather change. “Our preliminary finds present spectacular variations within the potential of the [space] vines to struggle downy mildew and phylloxera.”
Vines have additionally proven each decreased and elevated progress charges following their journey sans gravity. The scientists hope to deal with the vines which might be rising sooner, a type of choice that occurs in all breeding applications, Gaume explains.
As well as, the bacterial and fungi communities related to area vines displayed what Gaume calls “promising” modifications, although he declined to share specifics, explaining that extra experiments and evaluation must be carried out earlier than definitive particulars might be shared with the general public.
Higher wine
The bottles of wine saved with out gravity, as beforehand reported, tasted completely different — general, higher. Additional exams on the area wines have proven modifications within the ranges of polyphenols, antioxidants linked by some research to coronary heart well being.
Probably the most thrilling discoveries are nonetheless on the horizon: subsequent yr, the crew will do a micro-vinification of the grapes produced by the area vines. In 2024, in partnership with international vine nursery chief Mercier Group, they hope to start providing these disease-resistant vines to growers commercially.
Keep tuned.
