A European Satellite Is Falling From Space But No One Knows Where It Will HitMegan Gannon
Astronomer Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, who tracks satellite reentries, wrote on X that the space debris was a SpaceX Starlink 5693 satellite, which had been slowly falling from orbit since Dec. 6. You may like SpaceX Falcon 9 rocket debri...
Get a snapshot view of NASA's Upper Atmosphere Research Satellite (UARS), which will fall to Earth in 2011, in this SPACE.com infographic. The UARS satellite launched in 1991 and shut down in 2005.
(1)What keeps a satellite from falling to the earth? CA.Its rotation.B.Its orbit.C.Its speed.D.Its height.(2)What can we say about the Chinese Space Station? AA.It can be considered a satellite.B.It is below the Karman Line.C.It is circling the earth at 7km/s.D.It has ...
Therefore, these satellites must travel atabout 17,000 miles per hour to keep from falling back to the earth,while higher-orbiting satellites can travel more slowly.(离地球越近,引力就越强。因此,这些卫星必须以每小时17000英里的速度运行,以防止落回地球,而轨道较高的卫星运行速度更慢)”可知,高地球...

The Soviet Union's failed Kosmos 482 spacecraft will crash to Earth in the coming days after more than 50 years in orbit. Its homecoming may not spark the sorts of artificial meteor showers we're used to seeing from falling rocket bodies and other pieces ... More (Source: Space.com - ...
SCIENTISTS CHASED A FALLING SPACECRAFT WITH A PLANE TO UNDERSTAND SATELLITE AIR POLLUTION- A dramatic aircraft chase of a falling spacecraft has provided new insights into the fiery processes that accompany the atmospheric demise of retired satellites. The measurements will help scientists better underst...
Spectral mapping of the distribution of red material and trends in H2O ice band strengths across the satellites and rings can map out infalling dust from Uranus’s inward-migrating irregular satellites (Cartwright et al., 2018), similar to what is observed in the Saturnian system on Phoebe/...
The rockets take astronauts and man-made satellites into space. The satellites are used for communication weather monitoring and research. But how do satellites stay up without falling down? There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (...
