SpaceX is kicking off the morning of Memorial Day with a Falcon 9 flight about an hour after sunrise. The Starlink 6-60 mission will add another 23 spacecraft to the company’s growing mega-constellation of internet relay satellites, serving more than three million customers.
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested in astronomy in the first place. That seems to be the case for the authors of a new paper on the movement of jets coming out of black holes. Dubbing them “Death Star” black holes, researchers used data from the Very Long Baseline Array (VLBA) and the Chandra X-ray Observatory to look at where these black holes fired jets of superheated particles. And over time the found they did something the fiction Death Star could also do – move.
Skywatchers who plan to rise early and step outside on June 3 expecting to see a stunning display of visible planets will be quite disappointed, at the very least.
Here's what it was like seeing Ridley Scott's "Alien" on opening day in 1979, in honor of the iconic sci-fi horror film's 45th anniversary.
On Episode 112 of This Week In Space, Rod and Tariq talk with Rob Manning, Chief Engineer Emeritus of NASA's Jet Propulsion Laboratory, about Mars exploration and, in particular, Mars Sample Return.

SpaceX is preparing to launch its massive Starship rocket on its fourth flight test from its Starbase facilities in southern Texas as soon as June 5. The target launch date comes a little less than three months after Flight 3 on March 14.
On May 20th, 2024, an iceberg measuring 380 square kilometers (~147 mi2) broke off the Brunt Ice Shelf in Antarctica. This event (A-83) is this region’s third significant iceberg calving in the past four years. The first came In 2021, when A-74 broke off the ice sheet, while an even larger berg named A-81 followed in 2023. The separation of this iceberg was captured by two Earth Observation satellites – the ESA’s Copernicus Sentinel-1 and NASA’s Landsat 8 satellites – which provided radar imaging and thermal data, respectively.
The PREFIRE mission will launch the first of two CubeSats – depicted in this artist’s concept orbiting Earth – into space on Saturday, May 25, 2024, to study how much heat the planet absorbs and emits from its polar regions. These measurements will inform climate and ice models. Graphic: NASA/JPL-Caltech
Update 4:36 a.m. EDT: Rocket Lab confirms a successful deployment of NASA’s PREFIRE-1 cubesat.
Update 3:52 a.m. EDT: Liftoff occurred at 3:41 a.m. EDT. Good first and second stage burns. Kick stage ignition
Update 3:30 a.m. EDT: Countdown resumed for a new T-0 of 3:41 a.m. EDT.
Update 3:20 a.m. EDT: Countdown holding due to high ground winds.
Update 10:44 p.m. EDT: Rocket Lab set the T-0 liftoff time for the mission.
The James Webb Space Telescope has found three of the universe's earliest galaxies, and they could reveal a lot about galactic dynamics. Here's how.
NASA and Boeing are still working through "complicated" issues arising from a small Starliner spacecraft helium leak. Launch is June 1, but that's pending a flight readiness review.
Four zebrafish are alive and well after nearly a month in space aboard China’s Tiangong space station. As part of an experiment testing the development of vertebrates in microgravity, the fish live and swim within a small habitat aboard the station.
A new catalog of the masses and widths of 126 new exoplanets showcases the extreme and exotic nature of worlds beyond the solar system.
The hunt for new exoplanets continues. On May 23rd, an international collaboration of scientists published the NASA TESS-Keck Catalog, an effort to publicly release over 9000 radial velocity measurements collected by NASA’s space-based Transiting Exoplanet Survey Satellite (TESS) and the ground-based Keck Observatory, located in Hawai’i, and the Automated Planet Finder, located at the Lick Observatory in California. An accompanying analysis of these validated 32 new planetary candidates and found the masses of 126 confirmed planets and candidates with a wide range of masses and orbits. Let’s dig into some details.

After nearly three weeks of exhaustive tests and data analysis, NASA managers said Friday they are confident Boeing’s oft-delayed Starliner crew capsule can safely launch “as is” June 1, saying a small helium leak in the ship’s propulsion system does not pose a flight safety concern.
The joint Chinese-Pakistani cubesat mission was released by China's Chang'e 6 lunar far side sample return spacecraft on its way to the moon.
In just a few short years, NASA hopes to put humans back on the lunar surface. The first moonwalk in more than 50 years is scheduled for no earlier than September 2026 as part of the Artemis III mission. In preparation, astronauts, scientists, and flight controllers are conducting simulated spacewalks here on Earth.
