The first crewed launch of Boeing's Starliner spaceship will have to wait until at least Friday to give ground teams time to analyze a malfunctioning rocket valve, pushing back a high-stakes test trip to the International Space Station.
The mission has already faced years of delays and comes at a challenging time for Boeing, as a safety crisis engulfs the century-old aerospace titan's commercial aviation arm.
NASA is also banking on Starliner's success in order to achieve its goal of certifying a second commercial vehicle to carry crews to the orbital outpost.
Billionaire's 2nd SpaceX trip featuring spacewalk aims for early summer launch
Tuesday, 07 May 2024 16:17 Write a comment
Billionaire Jared Issacman, who flew to space once with SpaceX, is already set for launch No. 2 in early summer.
The mission calls for new spacesuits introduced this past weekend designed so the crew can survive the plan to suck out all of the air of the spacecraft and allow Issacman and a crewmate to make the first commercial spacewalk in history.
Flying on the Crew Dragon Resilience again, the mission dubbed Polaris Dawn is the first of up to three flights Issacman wants to fly, culminating in what is supposed to be the first crewed mission of SpaceX's Starship.
For now, though, the mission has to use SpaceX's existing rocket options, so he and his three crewmates will launch atop a Falcon 9 from Kennedy Space Center's Launch Complex 39-A. It will mark Issacman's return after his Inspiration4 mission in 2021.
That flight featured three crewmates chosen through a series of contests and fundraisers as well as a representative of his altruistic target, St. Jude Children's Research Hospital.
His crewmates for Polaris Dawn include two SpaceX employees and one of Issacman's pilot friends.

In the ongoing battle against atmospheric drag in low Earth orbit, which gradually degrades satellite trajectories, the emergence of ion thrusters presents a significant improvement in space navigation. Unlike traditional propulsion systems that utilize bulky and costly chemical propellants, ion thrusters offer a lighter, more economical alternative for adjusting satellite orbits.

Researchers at the University of Colorado Boulder have uncovered significant insights into why Venus, despite being similar in size and mass to Earth, contains minuscule amounts of water. Their findings were published on May 6 in the journal Nature.
The study focuses on a process called dissociative recombination, where hydrogen atoms are lost from Venus's atmosphere into space. This phe
