SpaceX has postponed the launch of another batch of Starlink internet satellites from Thursday as the company’s team in Florida prioritizes preparations for the launch of a four-man next week bound for the International Space Station.

Relativity Space plans to skip a final test-firing of its first fully stacked Terran 1 rocket at Cape Canaveral and proceed with a launch attempt March 8 for the methane-fueled, 3D-printed launcher, the company said Wednesday.
Astronomers have discovered a "runaway" black hole, potentially the first observational evidence that supermassive black holes can be ejected from their host galaxies.
Dust storms are a serious hazard on Mars. While smaller storms and dust devils happen regularly, larger ones happen every year (during summer in the southern hemisphere) and can cover continent-sized areas for weeks. Once every three Martian years (about five and a half Earth years), the storms can become large enough to encompass the entire planet and last up to two months. These storms play a major role in the dynamic processes that shape the surface of Mars and are sometimes visible from Earth (like the 2018 storm that ended the Opportunity rover’s mission).
Sending a lander to Venus presents several huge engineering problems. Granted, we’d get a break from the nail-biting entry, descent and landing, since Venus’ atmosphere is so thick, a lander would settle gently to the surface like a stone settles in water — no sky cranes or retrorockets required.
NASA's Curiosity Mars rover has photographed clear signs of ripples locked into a Martian rock, a sign of an ancient lake on the Red Planet's surface.
SpaceX says it's ready for its first-ever Starship orbital launch attempt in March, but still lacks a license to launch from the Federal Aviation Administration.
The two-day-old moon meets up with Jupiter tonight (Feb. 22), making a close approach and sharing the same right ascension in an arrangement known as a conjunction.
Now you can launch and crash vehicles for Kerbonauts in new and spectacular ways in the sequel releasing to the popular Kerbal Space Program space game Friday (Feb. 24).
Scientists examine how Titan's icy shell creates tides in the moon's subsurface ocean.
The James Webb Space Telescope found massive, mature galaxies inhabiting the universe so soon after the Big Bang that according to current theories they really shouldn't exist.
Blue Origin, Jeff Bezos' private spaceflight company, claims it has made major progress in developing a way to make solar panels using materials from the lunar surface.
An unusual stellar streak emerging from a distant galaxy might be a sign of a runaway supermassive black hole, scientists suggest.
A new Hubble Space Telescope image highlights a region in the dwarf satellite galaxy the Large Magellanic Cloud that is rich in stars.
Scientists analyzing videos of Ingenuity’s historic first flights on Mars are learning more about dust behavior on the Red Planet.
As we pass the show's 30th anniversary, we look back at the enduring legacy of Babylon 5, one of sci-fi's most underrated shows.
Crewmembers on the International Space Station are awaiting the fresh spacecraft, which will replace a leaky Soyuz currently docked with the orbiting complex.
On Wednesday (Feb. 22), the moon and Venus will make a close approach and also reach conjunction, which happens when they share the same right ascension.
The two brightest planets pass less than half a degree apart at dusk during a spectacular conjunction on the night of March 1st.

On Earth, geologists study rocks to help better understand the history of our planet. In contrast, planetary geologists study meteorites to help better understand the history of our solar system. While these space rocks put on quite the spectacle when they enter our atmosphere at high speeds, they also offer insights into both the formation and evolution of the solar system and the planetary bodies that encompass it. But what happens as a meteorite traverses our thick atmosphere and lands on the Earth? Does it stay in its pristine condition for scientists to study? How quickly should we contain the meteorite before the many geological processes that make up our planet contaminate the specimen? How does this contamination affect how the meteorite is studied?
