SpaceX on Tuesday postponed once more its attempt at launching a daring orbital expedition featuring an all-civilian crew that is aiming to carry out the first-ever spacewalk by private citizens.
The Polaris Dawn mission, organized by billionaire entrepreneur Jared Isaacman, had been set to lift off from NASA's Kennedy Space Center in Florida during a four-hour window early Wednesday.

How biofilms can help or hinder spaceflight
Wednesday, 28 August 2024 12:35 Write a comment
As humans spread into the cosmos, we will take a plethora of initially Earth-bound life with us for the ride. Some might be more beneficial or potentially harmful than others. And there is no lifeform more prevalent on Earth than bacteria. These tiny creatures and fungi, their long-lost cousins on the evolutionary tree, have a habit of clumping together to form a type of structure known as a biofilm.
Biofilms are ubiquitous in Earth-bound environments and have been noticed on space missions for decades. But what potential dangers do they pose? More interestingly, what possible problems can they solve?
A paper from a group of scientists focused on life support systems in the journal Biofilm provides a high-level overview of the state of the science of understanding how biofilms work in space and where it might need to go for us to establish a permanent human presence off-world.
The paper is divided into five sub-sections, each of which examines how biofilms might impact them.

SpaceX delays Polaris Dawn launch again with no new date set

Billionaire Jared Isaacman's return trip to space on the Polaris Dawn mission is having to wait a little longer after a launch pad issue forced one delay and now the weather has taken the next two launch opportunities off the board.
First, a helium leak on the launch pad Monday night forced SpaceX to hold off a planned overnight launch attempt of Isaacman and three crewmates aboard the SpaceX Crew Dragon Resilience atop a Falcon 9 rocket from KSC's Launch Pad 39-A. Then SpaceX said weather in the recovery area would take off both early Wednesday and early Thursday morning opportunities.
"Due to unfavorable weather forecast in Dragon's splashdown areas off the coast of Florida, we are now standing down from tonight and tomorrow's Falcon 9 launch opportunities of Polaris Dawn," SpaceX posted on X late Tuesday. "Teams will continue to monitor weather for favorable launch and return conditions."
It's uncertain if SpaceX would try for an early Friday morning launch opportunity.
"The ascent corridor is go, it's the splashdown locations day 5 that are not favorable," Isaacman posted late Tuesday to X.

NASA's Perseverance rover is tackling a steep new challenge on Mars.
The six-wheeled rover has spent the last 3 1/2 years roaming around the bottom of a crater. On Tuesday, it began climbing to the top.
The rover will go up 1,000 feet (305 meters) to the rim of Jezero Crater to dig up rock samples. Since landing on the red planet in 2021, Perseverance has collected 22 rock core samples from the floor of the crater, which was once filled with water.

NASA's Advanced Composite Solar Sail System (ACS3) has initiated deployment operations for its innovative solar sail. However, during the initial attempt to unfurl the sail, the process was paused when an onboard power monitor detected higher-than-expected motor currents. Despite this, communications, power, and attitude control for the spacecraft all remain normal. Mission managers are now focu Cluster concludes with controlled reentry over South Pacific

On September 8, 2024, the first of four satellites from ESA's long-running Cluster mission will reenter Earth's atmosphere, descending over the South Pacific Ocean's Uninhabited Area. This event marks the conclusion of the 24-year mission, which has significantly advanced our understanding of Earth's magnetic environment. Although the remaining three satellites will no longer conduct scientific
