A SpaceX Falcon 9 will make another attempt Sunday to launch 24 satellites for Amazon’s Project Kuiper internet service after three earlier attempts were scrubbed.
Thanks to the development of reusable rockets, rideshare programs, and other key innovations, the cost of sending payloads to space has steadily dropped in recent years. As a result, access to space is increasing for commercial space companies, universities, research institutes, and non-profits. To facilitate this trend, NASA has selected six companies through its Launch Services Program, which were awarded Venture-Class Acquisition of Dedicated and Rideshare Launch Services (VADR) contracts.
During the early days of our Solar System, giant impacts were common occurrences. Earth likely experienced such an impact that created our Moon, and Mars may have been struck by objects that created its asymmetrical surface features. But what about Venus?
3D printing is going to be a critical technology in space exploration, both for its ability to create almost any object, but also because it can utilize in-situ resources, at least in part. However, the more of those space resources are used in a print, the more the mechanical properties change from that on Earth, leading to problems with tensile or compressive strength. But a new paper from researchers at Concordia University hit a new milestone of how much lunar regolith can be used in a mixed feedstock for additive manufacturing, making it possible to use even more locally sourced material, and saving more launch cost, than ever before.
In 2024, an international team of astronomers launched the CANDELS-Area Prism Epoch of Reionization Survey (CAPERS), a program that would use data from the James Webb Space Telescope (JWST) to identify galaxies at "Cosmic Dawn." This cosmological period took place less than one billion years after the Big Bang and is when the first galaxies in the Universe formed. In a recent study, the CAPERS team confirmed the existence of a black hole at the center of a galaxy (designated CAPERS-LRD-z9) roughly 13.3 billion light-years away.

Two NASA astronauts, a Japanese flier and a Russian cosmonaut plunged back to Earth Saturday, safely splashing down in the Pacific Ocean near San Diego to wrap up a five-month mission.
A new executive order repeals a 52-year-old ban on commercial supersonic flights, while new technology can make supersonic flight quieter than ever before.
In a Q&A interview, author and science writer David Baron discusses the turn-of-the-century Mars craze, which he covers in his new book, "The Martians."
A four-legged robot tested under simulated Martian gravity jumps from wall to wall, demonstrating how future missions could navigate terrain too challenging for today's rovers.
In 1964, astronomers discovered the first black hole. It's called Cygnus X-1 and the evidence for its existence was discovered by x-ray detectors on a sub-orbital sounding rocket. Cygnus X-1 is about 7,300 light-years away and has about 21 solar masses. Since then, astronomers have discovered increasingly more massive black holes, including supermassive black holes (SMBH) at the heart of large galaxies like ours.
Astronomers using the Hubble Space Telescope have observed 3I/ATLAS, only the third known object from outside our Solar System to visit our neighbourhood. This interstellar interloper is putting on quite a show as it approaches the Sun, revealing secrets about visitors from the depths of space.
SpaceX's Crew-10 astronauts will return to Earth today (Aug. 9) after living on the International Space Station for nearly five months, and you can watch the action live.
The four members on SpaceX's Crew-10 mission are Earth-bound after bidding farewell to their Expedition 73 crewmates and departing the International Space Station.
For most of the past decade, forecasters have been able to use satellites to track these smoke plumes, but the view was only two-dimensional
Astronomers spot a rare stellar bridge in Abell 3667, revealing an aggressive galaxy merger and new clues about dark matter.
Astronaut James A. Lovell Jr., Apollo 13 mission commander, reads a newspaper account of the safe recovery of the problem plagued mission. Lovell is on board the USS Iwo Jima, prime recovery ship for Apollo 13, which was on a course headed for Pago Pago. From Pago Pago the astronauts flew to Hickam Air Force Base, Hawaii, where they were presented the Presidential Medal of Freedom by President Richard M. Nixon. Other Apollo 13 crew members were astronauts John L. Swigert Jr., command module pilot, and Fred W. Haise Jr., lunar module pilot. Image: NASA
James ‘Jim’ Lovell, one of the last seven surviving Apollo astronauts died on Thursday, Aug. 7, at the age of 97. A veteran of four spaceflights at the dawn of America’s human spaceflight program, he flew two missions in the Gemini program and then served on the crews of Apollo 8 and the ill-fated Apollo 13.
This quiz tests your knowledge of the astronauts who have stepped foot on the moon.
NASA astronaut Jim Lovell — a veteran of four spaceflights, including Apollo 8 and the near-disastrous Apollo 13 —passed away on Aug. 7, 2025 at the age of 97.
Black holes are among the most enigmatic and fascinating objects in the universe. These regions of spacetime exhibit such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside them. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Paramount’s hit sci-fi horror franchise returns in 2027 with more ultrasonic alien invaders.
The techniques used to target the asteroids could also be employed in tracking hazardous asteroids and interstellar objects.
