SpaceX continued a busy weekend with the launch of another batch of Starlink satellites from Cape Canaveral Space Force Station late Saturday night. Liftoff of the Falcon 9 from Space Launch Complex 40 occurred at 11:00 p.m. EST (0400 UTC).
On Episode 89 of This Week In Space, Tariq and Rod discuss the challenges of regulating spaceflight.
Unvisited by spacecraft for more than 35 years, Uranus inhabits one of the least explored regions of our solar system.
Lockheed Martin and Firefly Aerospace are combining to launch a demonstrator that aims to slash the time it takes spacecraft payloads to become operational.
There will be 20 total payloads being brought to the moon, five of which are NASA's.
A team of researchers led by University of Chicago astronomer Rafael Luque analyzed data acquired by both NASA’s Transiting Exoplanet Survey Satellite (TESS) and ESA’s CHaracterising ExOPlanet Satellite (Cheops) and found a unique planetary system. Orbiting a star cataloged as HD110067, this system contains six sub-Neptune planets. Incredibly, all six planets are orbiting in direct resonance with each other. The results of the work were published on November 29 in Nature.
In 1986, a gigantic iceberg separated from the Fichner-Ronne ice shelf in West Antarctica. It was so big that it became grounded, stuck to the seafloor, and remained in position for 40 years. Finally, it has now been pushed off the seafloor and has begun drifting in the Weddell Sea to a region in the South Atlantic called Iceberg Alley. Designated A23a, this monster berg measures 4000 sq km (1,500 square miles) and is about 400 meters (1,300 feet) thick – the world’s largest.
Six years of hard work and dedication paid off in spectacular fashion today, as the Educational Irish Research Satellite, EIRSAT-1, successfully blasted off from Vandenberg Space Force Base, California. Hitching a ride on a Space-X Falcon-9 launcher, the tiny satellite – measuring just 10.7cm x 10.7cm x 22.7cm – has now made history as Ireland’s first satellite!

Tech giant Amazon is adding a fifth rocket to launch its satellite internet constellation. In a surprise move on Friday afternoon, the company announced it purchased three flights aboard SpaceX’s Falcon 9 rockets to send batched of its Project Kuiper satellites to low Earth orbit.

On 1 December 2023, at 19:19 CET (18:18 GMT), Ireland's first satellite EIRSAT-1 launched from Vandenberg Space Force Base in California, USA.

Kicking off the month of December for SpaceX was a Falcon 9 ride share mission with a payload of 25 spacecraft on board. The launch from Vandenberg Space Force Base was headlined by the Korea 425 mission.

A Russian Progress cargo ship loaded with more than 5,500 pounds of supplies and equipment bound for the International Space Station blasted off from Kazakhstan early Friday, kicking off a two-day orbital chase.

These moonless evenings open up the deep sky. For many of us the viewing is especially crisp through the low-humidity December air. The Big Dipper lies low, Cassiopeia stands high, and the Andromeda Galaxy crosses the zenith.
Image: After being grounded on the ocean floor for well over four decades, the largest iceberg in the world is on the loose.
This month’s Sky Tour podcast introduces you to a “tower of brilliance” in the eastern evening sky, along with tips for finding four planets and watching mid-December’s impressive Geminid meteor shower.
Universe Today recently examined the potential for sending humans to the planet Venus despite its extremely harsh surface conditions. But while a human mission to the clouds of Venus could be feasible given the environmental conditions are much more Earth-like, a human mission to the second planet from the Sun could be (at minimum) decades away. With NASA sending humans back to the Moon in the next few years, and hopefully to Mars, what if we could send humans to another planetary body worth exploring, though it could have its own harsh environmental conditions, as well? What about Jupiter’s icy moon, Europa? It has a massive interior liquid ocean that could harbor life, and NASA is currently scheduled to launch its Europa Clipper spacecraft to this small moon in October 2024, arriving at Jupiter in April 2030. Therefore, given the exploration potential, should we send humans to Europa?
With NASA gearing up to send humans back to the Moon in the next few years with the Artemis missions with the goal of establishing a permanent outpost at the lunar south pole, nations are making efforts to contribute to Artemis and a permanent presence on our nearest celestial neighbor. Recently, the Italian Space Agency, formally known as Agenzia Spaziale Italiana (ASI), has taken steps to establish the first permanent outpost on the lunar surface, known simply as the Multi-Purpose Habitat (MPH). This endeavor was officially kicked by the ASI signing a contract with the French-based aerospace company, Thales Alenia Space, who specializes in space-based systems, including ground segments and satellites used for both Earth observation and space exploration.
The rich flow of scientific data—and stunning images—that comes from the Hubble Space Telescope is being interrupted by gyro problems. One of the telescope’s three remaining gyros gave faulty readings, and the Hubble automatically entered safe mode. In safe mode, science operations are suspended.
Pulsars are extreme objects. They’re what’s left over when a massive star collapses on itself and explodes as a supernova. This creates a neutron star. Neutron stars spin, and some of them emit radiation. When they emit radiation from their poles that we can see, we call them pulsars.
