How can we drift in space

Space exploration and exploration

Up-close exploration: orbiter technology

Mankind is a giant leap forward in exploration when exploring planets, moons, or asteroids up close. This is done with space probes that orbit the celestial body in an orbit - an orbit. The challenge for such orbiters: They have to travel great distances, and at the same time their systems have to function under extreme space conditions, because the data should be reliably transmitted to Earth.

OHB Sweden did pioneering work for European orbiter technology: in 2003 the company took partSMART-1 (Small Missions for Advanced Research in Technology) the first European space probe to the moon. She tested a solar-electrically powered ion drive, new navigation and communication technologies and examined the chemical composition of the lunar surface. This ESA mission gave space research important insights into the formation of the moon over four billion years ago.

Getting into the atmosphere safely: entry technology

Whenever we penetrate into space in space research and reach unknown celestial bodies, this poses new challenges for the entry technologies: Depending on the planet or moon and the speed of rotation, the atmospheric conditions are different. Spacecraft, for example, have to be prepared for this in their technical infrastructure so that they are not damaged when they enter the atmosphere and can do their job.

Arriving outside the earth without damage: technology for precise landings

The surface of the earth is largely known - and for the most part experts know how and where take-offs and landings can be carried out. If in doubt, they can be tested relatively easily. But even on the (earth) moon, trying it out is much more time-consuming. In general, landing safely and damage-free on foreign planets, moons or asteroids is a difficult discipline - and a real challenge for engineers. Because other gravitational forces, different surfaces and temperatures or winds that are difficult to calculate increase the technological demands on the systems. OHB has repeatedly done pioneering work in many studies and projects.
