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.

SpaceX is poised for another 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 is now set to lift off from NASA's Kennedy Space Center in Florida during a four-hour window beginning on Wednesday at 3:38 am loca NASA's Perseverance rover on Mars begins steep climb to rim of a crater

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.

SpaceX on Monday pushed back the historic launch of an all-civilian crew on an orbital expedition set to mark a new chapter in space exploration with the first spacewalk by private citizens.

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.

Ensuring precise Global Navigation Satellite System (GNSS) orbit and clock data is vital for various critical applications. A new method that integrates data from regional ground stations with measurements from Low Earth Orbit (LEO) satellites has been shown to significantly improve the accuracy of GNSS orbits, advancing precision from meters to centimeters.

On September 8, 2024, the first of the four Cluster satellites, known as Salsa, will reenter Earth's atmosphere in an uncontrolled "targeted reentry" over a remote area in the South Pacific Ocean. This event marks a significant moment in reentry observation as scientists seek to gather valuable data on satellite disintegration.

Scientists and engineers are ready to fly an infrared mission called EXCITE (EXoplanet Climate Infrared TElescope) to the edge of space.
EXCITE is designed to study atmospheres around exoplanets, or worlds beyond our solar system, during circumpolar long-duration scientific balloon flights. But first, it must complete a test flight during NASA's fall 2024 scientific ballooning campaign fr
