Shenzhou XV mission members conducted their fourth spacewalk on Saturday, surpassing previous crews, according to China Manned Space Agency.
In a news release on Sunday afternoon, the agency said that mission commander Major General Fei Junlong and Senior Colonel Zhang Lu completed the spacewalk and then returned to the Wentian science module.

A new NASA study offers an explanation of how quakes could be the source of the mysteriously smooth terrain on moons circling Jupiter and Saturn.
Many of the ice-encrusted moons orbiting the giant planets in the far reaches of our solar system are known to be geologically active. Jupiter and Saturn have such strong gravity that they stretch and pull the bodies orbiting them, causing moonqu China's space station achieves 100 pct regeneration of oxygen resources

SpaceX reschedules Starship test flight for Thursday

SpaceX has rescheduled for Thursday the first test flight of Starship, the most powerful rocket ever built, designed to send astronauts to the Moon, Mars and beyond, after a technical glitch forced a halt to the countdown.
A planned liftoff Monday of the gigantic rocket was called off less than 10 minutes ahead of the scheduled launch because of a pressurization issue in the first-stage boos Export control update on the way

Solar sails could guide interplanetary travel, says new study
Monday, 17 April 2023 19:50 Write a comment
Space travel has brought us to our next-door neighbor, the moon, and to the depths of our larger solar community inhabited by giants such as Saturn and Jupiter.
In 1982, Voyager 2 whisked past Uranus closer than any other spacecraft has since, and now is sailing—46 years after its launch—through the constellation of Pavo, some 179 light years from Earth.
But there have been few comparable satellite missions in recent years. Cost is the main obstacle, but time frame is also a factor. The design for such long journeys takes years to calculate, and planning and construction of a space vehicle would take about a decade. Factoring in the time a satellite would require to reach distant targets means our next peek into the stars will likely not come any time soon.
A team of scientists led by Slava Turyshev of the Jet Propulsion Laboratory at the California Institute of Technology, which launched the Voyager satellites back in 1977, is anxious to get space exploration back on track. The team proposes a novel means of travel that could get us to the stars faster and cheaper.

The moon may be the best place to transport rocket fuel
Monday, 17 April 2023 17:56 Write a comment
When astronauts return to the moon in the next few years, the plan is to have them stay for good while establishing a permanent outpost on Earth's nearest celestial neighbor. Like all space missions, a lunar outpost will require fuel for long-term sustainability, but would it be better to mine fuel on the moon or get fuel resupply from the Earth? This is what a team of researchers led by Bocconi University in Italy hope to address as they addressed the best option in terms of deriving fuel from either the Earth or the moon.
Mattia Pianorsi, who is a junior researcher of the Space Economy Laboratory at the SDA Boccini School of Management and a Ph.D. Candidate at the University of St. Gallen, recently told Universe Today the main objective of the study was to ascertain the economic and technical feasibility of mining fuel from the moon's water ice deposits or from the Earth.
Both options would use an orbiting depot (OD) which Pianorsi says would be used "as a distribution channel for satellites as well as rockets in space.
