Earth’s Twin Sister

During the Caelestis mission, Deimos-One will send an AI-powered swarm of robotic probes to study Venus’ dense atmosphere, topography, and geologic processes – and look for signs of life. In collaboration with our commercial and international partners, we aim to discover how Venus – which may have been the first potentially habitable planet in our solar system – transformed from a temperate world with rivers, lakes, and oceans, into a dry hellscape planet with crushing atmospheric pressures and temperatures hot enough to melt lead. It will make one of the first returns to Earth’s sister planet in more than thirty years.

HOW WE ARE GOING TO GET THERE

Let the Journey Begin

The Caelestis mission will leverage a unique, multi-dimensional viewpoint of the Venusian environment to study the poorly understood meteorology of the middle cloud region and search for macroscopic life signatures within the atmospheric habitable zone.

Space Launch Systems

The AI powered Vulcan hive will be carried into the Venusian atmosphere on a commercial rocket. This Space Launch System was designed to be powerful, but also flexible and efficient as it seeks to launch the first private research mission to Venus.

Exploration Systems

Designed to be a multi-mission capable space vehicle, the Vulcan probe was built to support deep space exploration, even in harsh conditions. The hive will enter the upper atmosphere and study the environment at an altitude of 50 to 70 kilometers.

Landing Systems

The probes will carry scientific instrumentation to survey and measure the composition of Venus’ atmosphere, collect samples, and capture high-resolution photographs. They will conduct balloon-assisted hover operations until they descend and make make surface landing.

Sustainable Exploration

We believe that sustainable interplanetary exploration has the power to fill in humanity’s knowledge gaps about our universe – ultimately improving life here on Earth.

Mission Profile 

Unlike previous missions to Venus, which have relied on orbit insertion, the CAELESTIS probes will make direct atmospheric entry. The mission sequence will consist of an Earth launch and escape, Venus arrival, direct atmospheric entry and descent, balloon deployment, balloon failure, and a surface landing.

Step 1

Earth launch & escape

Step 2

Venus arrival & probe release

Step 3

Atmospheric entry & descent

Step 4

Balloon deployment & hover operations

Step 5

Surface landing + data collection

AI Powered Research

Robotic Vulcan probes will survey and measure the composition of Venus’ atmosphere, collect samples, and capture high-resolution photographs while hovering at roughly 55 km above the planet’s surface.

Fun Facts About Venus

The planet is often called "Earth’s twin" because they’re similar in size and structure. 

4.503 billion years

Venus is the closest planet to Earth, but its proximity to our planet depends on the orbits of both. At its farthest, Venus lies 162 million miles (261 million kilometers) from Earth, but it can reach as close as 24 million miles (38 million km).

Venus rotates very slowly on its axis – so one day on Venus lasts 243 Earth days, or roughly 5,832 hours. 

Venus orbits the Sun faster than Earth, so one year on Venus is roughly 225 Earth days, making a Venusian day longer than its year. 

Carbon Dioxide, Nitrogen

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system. Surface temperatures on the planet are about 900 degrees Fahrenheit (475 degrees Celsius) – which is hot enough to melt lead.

Venus is permanently shrouded in thick, toxic clouds of sulfuric acid that begin at an altitude of roughly 28 to 43 miles (45 to 70 kilometers). Some researchers theorize microbes may exist high in the clouds where the pressure is similar to Earth’s surface and the temperatures are much cooler. Phosphine, a possible indicator of microbial life, has also been observed in the clouds.

Deimos-One is at the frontier of scientific research and space exploration

We are developing solutions to help us better understand our universe and improve the human experience. Combining rigorous academic research with state-of-the-art space technology, we hope to make discoveries that will improve life on Earth and promote a cleaner, safer, sustainable world. 

Exploration

We are focused on developing spaceflight technology that will reduce the cost of access to space and provide for more research opportunities in our solar system and beyond.

Sustainability

We are committed to building a future where access to space is affordable, frequent, and reliable for everyone – our next-generation family of American made space vehicles will power us into this reality.

Mission

Our mission is to build an interplanetary pathway that connects earth to the universe around it. Our space vehicles are built to support a better future and promote a cleaner, safer, sustainable World.
