American Startup Varda Space Receives US$ 187 Million to Accelerate Drug Production in Microgravity and Expand Operations Beyond the ISS

Varda Space Industries, a company from the United States, raised US$ 187 million in its latest funding round. The announcement was made in a press release on Thursday, July 10. With this, the total raised by the company reaches US$ 329 million. Varda Space’s focus is on manufacturing drugs in a microgravity environment.

The round was led by Natural Capital and Shrug Capital. Other investors included billionaire Peter Thiel, Lux Capital, and Founders Fund.

According to the company, the new infusion of resources will help accelerate the development of drugs that would be impossible to produce on Earth.

Microgravity to Create New Formulations

Varda Space claims that space environments allow for a different crystallization of pharmaceutical materials.

This process can result in more effective or stable drugs. The company believes that microgravity conditions enable new formulations that would not be feasible on terrestrial soil.

One cited example involves a previous study by pharmaceutical company Merck. In 2023, the company conducted research on the International Space Station that showed a more stable version of pembrolizumab, an ingredient in the cancer drug Keytruda.

During its first mission, called W-1, Varda managed to grow crystals of the anti-HIV drug ritonavir.

The experiment took place aboard a spacecraft that orbited the Earth at low altitude. The company highlights that it was the first time this type of processing was done outside the International Space Station (ISS).

Mass Production of Drugs Is on the Agenda

The startup is also setting its sights on larger-scale production. According to co-founder Delian Asparouhov, the company’s current vehicles can bring back to Earth about 50 kilograms of active pharmaceutical ingredient.

He states that, in some cases, this is equivalent to a complete production batch for a quarter.

According to Varda Space, the concept of “mass production” does not require larger spacecraft. The current model already meets the needs for certain high-value-added drugs.

Fourth Mission Underway and Physical Expansion

The company has already completed three successful launch and return missions. A fourth mission is in orbit, and the fifth is scheduled for later this year.

Varda was founded by Will Bruey, a former SpaceX engineer, and Delian Asparouhov from Founders Fund.

Recently, the company also expanded its physical presence. It opened a new office in Huntsville, Alaska, and a lab in El Segundo, California.

This lab will be used to crystallize biological drugs and improve their formulations.

Fourth Mission Underway and Physical Expansion

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Brazil filled the Northeast with wind turbines but now faces the side effect of 705 giant blades reaching the end of their lifespan by 2032 just in Rio Grande do Norte, while the world projects 43 million tons of waste by 2050.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

10 giant tortoises are reintroduced and, in just 6 months, trigger changes that lead scientists to investigate a phenomenon absent for 180 years; the numbers recorded on the island impress researchers from around the world.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

A former SpaceX engineer left rockets to reinvent home construction and founded a startup that manufactures wall panels from a grass that grows about 15 centimeters per day.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

How much does it cost to install gutters in a house in 2026? See the average costs of materials, labor, and the most common extra expenses that may arise during installation.

The United States government approved a potential sale of 100 portable Stinger anti-aircraft missiles to the Brazilian Army, in a package estimated at around 330 million dollars that still depends on negotiations between the two countries.

Cheaper than Fiat Pulse, Renault Kardian, and Volkswagen Tera: with a 2.0 turbo engine of 190 hp, 30.6 kgfm torque, automatic transmission, and Swedish safety package, this premium hatch delivers sports car performance at the price of a new compact: meet the Volvo V40 T4 Momentum 2017.
