SpaceX said Tuesday a solar storm causing more atmospheric drag in low Earth orbit will destroy as many as 40 of 49 new Starlink internet satellites launched from Florida last week.
NASA's James Webb Space Telescope has to stay super cool to observe the cosmos. How does it beat the heat? Black paint.
Uranus and Neptune are similar planets in many ways. Both are ice giant worlds, both have atmospheres rich in methane, and both have a bluish color. But while Uranus has a pale blue-green hue, Neptune has a deep blue color. But why? Why would two planets so similar in size and composition appear so different? According to a recent study, the answer lies in their aerosols.
The rover topped 800 feet with a self-drive function.
Ingenuity aced a 100-second sortie on Tuesday (Feb. 8), its 19th Red Planet flight overall but its first since Dec. 15. A dust storm pushed the liftoff date back by more than a month.
The Moon has orbited Earth since the Solar System’s early days. Anyone who’s ever spent time at the ocean can’t fail to notice the Moon’s effect. The Moon drives the tides even in the world’s most remote inlets and bays. And tides may be vital to life’s emergence.
The Copernicus Sentinel satellite missions measure and image our planet in different ways to return a wealth of complementary information so that we can understand and track how our world is changing, and how to better manage our environment and resources. Thanks to the benefits of different types of data from two particular Copernicus Sentinel missions and an ingenious new dataset tool, people working in the agriculture sector, but who are not satellite data experts, can monitor the health and development of crops, right down to each crop in individual fields.
Lockheed Martin will build the Mars Ascent Vehicle, a small rocket that will launch pristine Red Planet samples back toward Earth a decade or so from now.
Eccentricity is a measure of how circular an orbit is. An eccentricity of 0 means that the orbit a perfect circle. Anything between 0 and 1 is an elliptical orbit. An eccentricity of exactly 1 gives a parabola, which isn’t much or an orbit at all, but rather an escape trajectory. Finally, a value greater than 1 is an orbit with the shape of a hyperbola, which is also an escape trajectory.
NASA's Curiosity rover has left plenty of marks on Mars over the past nine-plus years, and the Red Planet is returning the favor.
The Moon is sure to be a hotspot of economic activity as human commercial endeavors start to expand into space. Not only is it a ball of resources with a relatively small gravity well, but it also happens to be our nearest neighbor. But to unlock that potential, companies will have to build up an infrastructure that will allow for the exploitation of those resources. Enter Quantum Space, a new start-up from a group of heavy-hitting space experts looking to help make that potential a reality – by building a robotic spaceport around the moon.
Seeing the same target again has the comfort of a beloved rerun, while offering the opportunity for new discoveries.
Some astronomers say the collision is "not a big deal," but to a space archaeologist like me it's quite exciting.
The planet Venus has returned to the early morning sky and has established itself as a dazzling morning lantern, emerging into view from beyond the east-southeast horizon before 5 a.m. local standard time.
India plans to give landing on the moon a second try with its Chandrayaan 3 mission, which is now targeted to launch in August.
The Russian space agency released a proposal to allow its Progress cargo ships to arrive in a single orbit, an unprecedented two-hour flight.
Earth and even the sun are puny compared to a mighty, hulking source of gamma-rays.
The rocket stage helped heft the Echostar 23 satellite to orbit in 2017.
Billions of years ago, Mars was a much different place than it is today. During the same period when life was first emerging on Earth, Mars had a thicker atmosphere, warmer surface temperatures, and flowing water on its surface. Evidence of this warmer, wetter past is preserved on the planet’s surface today in the form of river channels, lakebeds, alluvial fans, and sedimentary deposits. When this period began, and how long it lasted, remains the subject of much debate for scientists.
A SpaceX rocket's upper stage was caught on camera careening toward a collision course with the moon.
