Mid-level flare erupts from sun

The sun emitted a mid-level solar flare on Jan. 20, 2022, peaking at 1:01 a.m. EST. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.

Image: Rolling stones on Mars

There's more to this image of Mars than first meets the eye: nestled in the detail of the cliff face that cuts through this scene are signs of geology in motion. Zooming in reveals several boulders that have fallen from the ...

Plato exoplanet mission gets green light for next phase

Plato, ESA's next-generation planet hunting mission, has been given the green light to continue with its development after the critical milestone review concluded successfully on 11 January 2022.

Ocean physics explain cyclones on Jupiter

Hurtling around Jupiter and its 79 moons is the Juno spacecraft, a NASA-funded satellite that sends images from the largest planet in our solar system back to researchers on Earth. These photographs have given oceanographers ...

Our galaxy's most recent major collision

One of the characteristic features of modern cosmology is its description of how galaxies evolve: via a hierarchical process of colliding and merging with other systems. Nowhere in the universe do we have a clearer view of ...

2029 will be the perfect year to launch a mission to Sedna

Object 90377 Sedna—a distant trans-Neptunian object known best for its highly elliptical, 11,390-year long orbit—is currently on its way toward perihelion (its closest approach to the sun) in 2076. After that, Sedna will ...

Spacecraft

A spacecraft is a craft or machine designed for spaceflight. On a sub-orbital spaceflight, a spacecraft enters space then returns to the Earth. For an orbital spaceflight, a spacecraft enters a closed orbit around the planetary body. Spacecraft used for human spaceflight carry people on board as crew or passengers. Spacecraft used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft that leave the vicinity of the planetary body are space probes. Robotic spacecraft that remain in orbit around the planetary body are artificial satellites. Starships, which are built for interstellar travel, are so far a theoretical concept only (aside from a handful of interstellar probes such as Pioneer 10 and 11, Voyager, and New Horizons).

Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, planetary exploration and space tourism. Spacecraft and space travel are common themes in works of science fiction.
