- Dragon spacecraft heads back from station June 16 — NASA
The uncrewed SpaceX Dragon will depart the International Space Station carrying completed experiments and station hardware. NASA will provide live coverage of the undocking and splashdown sequence. The 34th SpaceX resupply mission marks another routine cargo return in the ongoing commercial resupply cadence. Watch windows open next Tuesday with real-time updates from mission control.

The four-person crew discusses how test-flying experience prepares them for the complexities of landing near the lunar south pole. The episode of Houston We Have a Podcast captures their reactions to receiving the assignment through an unexpected HR meeting format. Listeners hear directly about the training timeline leading to the first crewed lunar landing since 1972. The discussion highlights coordination between Orion, the Human Landing System, and Gateway elements still in development.

Participants can submit their names to fly aboard the upcoming infrared observatory designed to survey wide areas of the sky. The mission will measure distances to millions of galaxies and search for planets in the Milky Way using microlensing. A digital boarding pass is available now through the dedicated NASA portal. Data from Roman is expected to complement narrower-field observations from other telescopes. Source: my.nasa.gov - X-59 jet breaks sound barrier in first supersonic test — Live Science
The experimental aircraft reached Mach 1 while engineers measured the resulting pressure signature on the ground. NASA designed the long, slender shape to reshape the shock waves into a softer thump rather than a loud boom. This milestone advances the agency’s goal of enabling supersonic flight over land without disturbing communities. Follow-on flights will refine the acoustic data before any potential regulatory changes. Source: Google News - Pioneer 10 crossed into interstellar space 43 years ago — Astronomy Magazine
On June 13, 1983, the spacecraft became the first to leave the solar system on an escape trajectory. It had already achieved the first flybys of Jupiter and the asteroid belt plus the first crossing beyond Mars. Radio contact continued until 2003, after which the probe continued outward at roughly 12 km per second. Its plaque remains the first physical message sent toward potential interstellar recipients.

The two planets appeared to draw nearer in Earth’s sky even as their actual orbital distances increased. The composite image captures the changing angular separation night after night from a single observing site. Such alignments occur regularly but rarely receive this level of continuous documentation. Observers can still catch the pair low in the west after sunset this month. Source: space.com - Japanese rover transformed on the Moon like a Transformer — Space.com
The autonomous sphere rolled across the surface before unfolding into a wheeled robot for closer inspection. It operated for a short period in 2024, demonstrating shape-shifting mobility without human intervention. The design addressed the challenge of traversing both flat plains and small craters with one platform. Engineers are now evaluating similar concepts for future lunar and asteroid missions.

The white paper outlines a fleet of small satellites that would rendezvous with multiple near-Earth objects and attach tracking beacons. Remote sensing alone cannot determine internal composition, so the probes would provide direct surface and subsurface measurements. The concept was submitted to the U.K. Space Agency’s 2035 Space Frontiers program. Multiple targets could be visited with far lower mass than a single large spacecraft.

Iron meteorites and chondrites show phosphorus-to-nitrogen ratios that challenge earlier models of how Earth acquired these elements. The work points to Jupiter’s early migration as a key distributor of material across the young solar system. Samples from different formation regions reveal distinct chemical fingerprints preserved since the protoplanetary disk era. Further laboratory analysis of additional meteorites is planned to test the revised timeline. Source: universetoday.com - Comet 220P/McNaught brightens after outburst — Astronomy Magazine
The comet recently jumped from 18th to much brighter magnitude while moving through southern Pisces. Observers with modest telescopes can locate it near Saturn in the morning sky. Outbursts like this are thought to result from sudden exposure of fresh ice on the nucleus. Continued monitoring will show whether the increased activity persists through the coming weeks.

The object existed 12.9 billion years ago and already hosted a black hole of enormous mass. Its spectrum shows rapid accretion despite the limited time available after the Big Bang. Such early monsters suggest either faster seed formation or more efficient feeding than current simulations predict. Follow-up observations with larger telescopes will search for similar objects at even greater distances.

Proposed constellations of data-processing satellites would add bright, moving sources across wide sky fields. Ground-based telescopes already contend with increasing numbers of low-Earth orbit objects during long exposures. The concern centers on both direct glare and scattered light that could compromise faint-object surveys. Operators and astronomers are beginning discussions on mitigation strategies before the first launches.

The Canadian firm has secured additional contracts supporting national satellite and exploration programs. Work includes contributions to communications and Earth-observation systems that reduce reliance on foreign providers. The contracts align with long-term goals for independent access to space data and technology. Domestic industry capacity is expected to grow through these sustained commitments.

The company’s valuation now reflects investor interest in artificial-intelligence applications alongside launch services. NASA must navigate how a publicly traded partner balances shareholder expectations with government mission priorities. Existing contracts for crew and cargo remain in place, yet future negotiations may incorporate different financial oversight. Industry analysts are watching whether the new structure affects bidding on lunar and Mars architecture work.

Japan’s new flagship vehicle lifted off from Tanegashima carrying six satellites after last year’s payload loss. The flight demonstrated reliable performance of the main engines and upper stage. Recovery of the launch cadence supports Japan’s plans for both government and commercial payloads. Additional missions are scheduled to restore full operational confidence in the system.

Cosmic Spotlight
The record-breaking quasar offers a rare window into how supermassive black holes assembled when the universe was less than a billion years old. Its extreme luminosity and rapid growth imply seed masses or accretion rates that current models struggle to produce. Spectra already show the surrounding gas is being pushed outward at high speeds, hinting at early feedback that could shape galaxy evolution. Next, larger surveys will hunt for more examples at comparable distances to test whether this object was typical or an outlier. What seed-formation channel allowed such rapid growth so soon after the Big Bang?
Cosmic Deep Dive: How Phosphorus Ratios Trace Early Solar-System Mixing
If every phosphorus atom on Earth arrived in a single teaspoon of material, that teaspoon would still outweigh an entire mountain range. In the swirling disk of gas and dust that became our solar system, Jupiter’s growing gravity acted like a giant traffic controller, flinging icy and rocky bodies inward and outward on chaotic paths. Iron meteorites that formed closer to the Sun carry one phosphorus-to-nitrogen signature, while younger chondrites record a distinctly different ratio after Jupiter’s migration stirred the inventory. The difference is measurable down to parts per million, revealing exactly when and where the ingredients for oceans and biology were delivered. Yet the precise timing of Jupiter’s first inward-then-outward journey remains an open question that no current sample set can fully pin down.
