The Sun rises on the morning of July 31, 2025, ahead of NASA’s SpaceX Crew-11 mission launch from NASA’s Kennedy Space Center in Florida. The launch was postponed due to an unfavorable weather forecast. Teams are now targeting 11:43 a.m. EDT Friday, Aug. 1.

NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov will launch to the International Space Station, where they will perform research, technology demonstrations, and maintenance activities.

A NASA photographer captured the sunrise on July 31, 2025, ahead of NASA's SpaceX Crew-11 launch attempt. The Crew-11 mission will send NASA astronauts Zena Cardman and Mike Fincke, along with JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui and Roscosmos cosmonaut Oleg Platonov, to the International Space Station aboard SpaceX’s Dragon spacecraft and Falcon 9.

Collaboration has always been a hallmark of space research. Experts in different disciplines come together to work towards a common goal, and many times achieve that. One of the current goals of space exploration is long-term settlement of the Moon, and in order to achieve that goal, engineers and astronauts will have to deal with one of the thorniest problems on that otherworldly body - dust. Lunar dust is much harder to deal with that Earth’s equivalent, as it is sharp, charged, and sticks to everything, including biological tissue such as lungs, and even relatively smooth surfaces like glass. Several research groups are working on mitigation techniques that can deal with lunar dust, but a new cross-collaborative group from the University of Central Florida is developing a coating, testing it, and simulating all in one project, with the hopes that someday their solution will make it easier for astronauts to explore our nearest neighbor.

In January of 2024, the company Astrobiotic was set to make history with the first privately-developed lander, named Peregrine, to reach the Lunar surface, sent aboard a United Launch Alliance’s Vulcan Centaur rocket.

In the young V883 Orionis system, ALMA observations have revealed signatures of complex organic compounds such as ethylene glycol and glycolonitrile – potential precursors to amino acids, DNA, and RNA. These findings indicate that the building blocks of life may not be limited to local conditions but could form widely throughout the Universe under suitable circumstances.

Technicians have successfully installed two sunshields onto NASA’s Nancy Grace Roman Space Telescope’s inner segment. Along with the observatory’s Solar Array Sun Shield and Deployable Aperture Cover, the panels (together called the Lower Instrument Sun Shade), will play a critical role in keeping Roman’s instruments cool and stable as the mission explores the infrared universe.

The team is on track to join Roman’s outer and inner assemblies this fall to complete the full observatory, which can then undergo further prelaunch testing.

“This shield is like an extremely strong sunblock for Roman’s sensitive instruments, protecting them from heat and light from the Sun that would otherwise overwhelm our ability to detect faint signals from space,” said Matthew Stephens, an aerospace engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The sunshade, which was designed and engineered at NASA Goddard, is essentially an extension of Roman’s solar panels, except without solar cells. Each sunshade flap is roughly the size of a garage door — about 7 by 7 feet (2.1 by 2.1 meters) — and 3 inches (7.6 centimeters) thick.

“They’re basically giant aluminum sandwiches, with metal sheets as thin as a credit card on the top and bottom and the central portion made up of a honeycomb structure,” said Conrad Mason, an aerospace engineer at NASA Goddard.

This design makes the panels lightweight yet stiff, and the material helps limit heat transfer from the side facing the Sun to the back—no small feat considering the front will be hot enough to boil water (up to 216 degrees Fahrenheit, or 102 degrees Celsius) while the back will be much colder than Antarctica’s harshest winter (minus 211 Fahrenheit, or minus 135 Celsius). A specialized polymer film blanket will wrap around each panel to temper the heat, with 17 layers on the Sun side and one on the shaded side.

The sunshade will be stowed and gently deploy around an hour after launch.

“The deploying mechanisms have dampers that work like soft-close hinges for drawers or cabinets, so the panels won’t slam open and rattle the observatory,” Stephens said. “They each take about two minutes to move into their final positions. This is the very first system that Roman will deploy in space after the spacecraft separates from the launch vehicle.”

Now completely assembled, Roman’s inner segment is slated to undergo a 70-day thermal vacuum test next. Engineers and scientists will test the full functionality of the spacecraft, telescope, and instruments under simulated space conditions. Following the test, the sunshade will be temporarily removed while the team joins Roman’s outer and inner assemblies, and then reattached to complete the observatory. The mission remains on track for launch no later than May 2027 with the team aiming for as early as fall 2026.
