Next up is preparation for the following Dragon mission later this summer.
- Hubble Captures Two Galaxy Clusters Merging — NASA
The image shows CL0016+1609, also known as MACS J0018.5+1626, one of the brightest X-ray clusters known. X-ray data revealed the system is two clusters aligned along our line of sight and in the process of merging. The observations add to extensive radio and X-ray studies of the object. Hubble’s visible-light view highlights the distorted galaxies within the colliding system. Follow-up papers will examine how the merger affects galaxy evolution.

Researchers refined criteria for identifying potentially habitable worlds around other stars. The updated framework incorporates atmospheric retention and stellar activity levels. It reduces the list of high-priority targets for future telescopes. The work helps observers allocate limited observation time more effectively. Scientists will test the model against new James Webb data releases.
- Canada’s ESA Investment Opens Lunar Missions — SpaceQ
Canada committed record funding to the European Space Agency, securing two lunar exploration opportunities. The investment supports Canadian instruments and technologies on upcoming European landers. It strengthens collaboration on surface science and resource prospecting. Program managers will now finalize instrument selections and timelines. Watch for the first hardware integration milestones in the coming year.
- Texas Grape Seeds Head to Space Station — Space News
Hundreds of wine-grape seeds from Texas A&M AgriLife will spend roughly six months aboard the ISS. Cosmic radiation exposure will be studied after the seeds return for planting. Researchers aim to produce the first wine from space-exposed grape seeds. The experiment tests how radiation alters seed genetics and growth. Results are expected after the samples complete post-flight analysis.
- Blue Origin Starts Rebuilding New Glenn Pad — SpaceNews
Work has begun on the launch pad damaged in a New Glenn explosion less than three weeks ago. The company targets a return to flight by the end of the year. Engineers are assessing structural repairs and safety systems. The effort keeps the heavy-lift rocket on schedule for future national-security and commercial missions. Next milestone is completion of pad certification tests.
- Quantum Space Wins Orbital Refueling Contract — SpaceNews
The Pentagon awarded Quantum Space a contract to develop a fuel-transfer spacecraft for the U.S. Space Force. The vehicle is slated for delivery by 2028. The project will demonstrate propellant transfer between satellites in orbit. Success would extend satellite lifetimes and reduce launch mass requirements. Early design reviews are scheduled for later this year.
- ESA Aims for Quicker Lunar Lander Flights — Aviation Week
The agency is studying ways to shorten development timelines for future Moon landers. Faster cadence would support more frequent science and technology demonstrations. Planners are examining reusable elements and streamlined qualification processes. The goal is to reduce the gap between missions while maintaining reliability. Concept studies will feed into the next ESA ministerial meeting.
- Oddball Hot Jupiter Expands Planet Formation Ideas — Nanowerk
Observations of an unusually hot gas giant are challenging standard models of planetary migration. The planet’s extreme temperature and orbital distance suggest new pathways for gas-giant formation. Data show atmospheric chemistry that differs from cooler Jupiters. Researchers are using the findings to update simulations of early solar-system dynamics. Follow-up spectroscopy will map the planet’s temperature structure in greater detail.
- Perseverance Rover Passes Marathon Distance on Mars — Space.com
NASA’s Perseverance has now driven more than 26.2 miles across Jezero Crater. The distance matches a terrestrial marathon and sets a new record for the rover. Scientists are using the extended traverse to sample diverse rock units. The data will help reconstruct the crater’s ancient lake history. The team will continue mapping the route toward the next sampling area.
- Pegasus Rocket Chosen for Swift Orbit Rescue — Northrop Grumman
Northrop Grumman’s Pegasus will launch the spacecraft that will raise the Swift Observatory’s altitude. The boost will extend the mission’s operational life by countering atmospheric drag. The mission combines NASA, Katalyst Space, and Northrop Grumman expertise. Launch is planned once the servicing vehicle completes final testing. Success would demonstrate a new approach to extending aging observatories.
- Relativity Space Joins NASA Mars Science Effort — SciGuySpace
NASA announced a public-private partnership with Relativity Space to advance Mars exploration. The collaboration will explore new technologies for future science missions. It builds on earlier work between the company and agency scientists. The partnership aims to lower costs while increasing payload capacity. Details on specific mission concepts will emerge in coming months.
- Mirror Stability Key to Future Exoplanet Work — Mirage News
Precise control of telescope mirrors is emerging as a critical requirement for detecting small exoplanets. Vibrations and thermal changes can blur the tiny signals needed for atmospheric characterization. Engineers are developing new stabilization techniques for the next generation of space telescopes. The improvements will directly affect the search for Earth-like worlds. Prototype tests are already underway in laboratory settings.
- Moon Passes Near the Sickle of Leo Tonight — Astronomy Magazine
After sunset, the Moon will appear close to the Sickle asterism in Leo. Observers can watch the pair low in the western sky before they set. The geometry offers a good chance to spot earthshine on the lunar surface. Binoculars will reveal the stars of the Sickle alongside the Moon. Clear western horizons will give the best views.
Ariane 6’s record flight with 36 Amazon satellites marks the first use of the upgraded boosters carrying 14 extra tonnes of propellant each. The added propellant directly increases payload capacity, moving Europe closer to competing with larger vehicles on commercial constellation deployments. Engineers will now compare actual performance against pre-flight models to decide whether the new configuration becomes the baseline for future missions. How many more satellites will ride this version before the next design iteration appears?
Picture a gas giant orbiting so close to its star that its dayside temperature exceeds 2,000 °C—hot enough to vaporize rock and keep an entire hemisphere glowing like molten metal. Radiation from the star slams into the upper atmosphere, breaking apart molecules and driving a powerful day-to-night wind that can reach thousands of kilometres per hour. On the nightside the temperature drops sharply, allowing some of those vaporized materials to condense into clouds that the winds then carry back into daylight, where they evaporate again in a continuous cycle. The whole process repeats on timescales of hours, not years, creating a global heat engine that astronomers can watch in real time with infrared telescopes. Yet no current model fully explains why some of these worlds appear to be losing atmosphere at rates far higher than expected while others hold onto theirs despite similar conditions. What hidden variable—perhaps magnetic fields, interior heat, or the star’s youth—decides whether a hot Jupiter keeps or sheds its outer layers?
New data keep arriving from every corner of the solar system and beyond.
