The proposed $1 billion plus-up for the X-37B program is part of a pot of money dedicated to the “Enhancement of Department of Defense Resources to Improve United States Indo-Pacific Command,” with a ...

The planet's orbit also plays a crucial role. A highly elliptical orbit, like that of Kepler-735c, can lead to extreme climatic variations. The presence of liquid water is another essential criterion.

Aerobraking brings a spacecraft from a large, circular orbit into a highly elliptical orbit, into a smaller, more circular one. Moneya/Wikimedia Commons, CC BY-SA ...

Illustration showing the highly elliptical orbit of Europe’s two Proba-3 satellites, which as an apogee (or top of orbit) of around 60,000 kilometers and perigee of 600 km. Coronagraph ...

When a spacecraft arrives at Mars, it does so in a hyperbolic orbit. While an elliptical orbit is closed, a hyperbolic orbit doesn’t go all the way around a planet. Maxmath12/Wikimedia Commons ...

Instead, it was trapped in a highly elliptical orbit that has persisted for 53 years. The spacecraft broke apart shortly after launch.

Spacecraft that orbit around Earth do so in two types of orbits: circular and elliptical. In a circular orbit, the spacecraft is always at the same distance from the center of the Earth.

But Langbroek and others believe the landing capsule itself — a spherical object about 3 feet (1 meter) in diameter — has been circling the world in a highly elliptical orbit for the past 53 ...

Earth with a highly elliptical orbit would experience extreme temperature swings; how would life adapt? The tables have turned, and Putin’s Russia is now in dire trouble How to hard boil eggs ...

This flight for the X-37B was unique for several reasons. This mission utilized a SpaceX Falcon Heavy rocket to go a farther distance into pace and put itself in a “highly elliptical” orbit.

While in orbit, Mission 7 tested "space domain awareness technology experiments" that aim to improve the United States Space Force’s knowledge of the space environment, the agency said.
