Why the $4.1 billion launch cost of NASA’s Moon rocket could destroy it
Posted by Atanas Atanasov in category: space travel
That’s over double the original expected launch cost.
NASA’s Space Launch System is supposed to ferry astronauts to the Moon, but at an estimated $4.1 billion per launch, it may be doomed before it ever gets off the ground.

NASA Releases Details on how Starship Will be Part of its Return to the Moon
Posted by Chima Wisdom in categories: engineering, government, law, space travel
The path back to the moon is long and fraught with danger, both in the real, physical sense and also in the contractual, legal sense. NASA, the agency sponsoring the largest government-backed lunar program, Artemis, has already been feeling the pain on the contractual end. Legal battles have delayed the development of a critical component of the Artemis program – the Human Landing System (HLS). But now, the ball has started rolling again, and a NASA manager recently reported the progress and future vision of this vital part of the mission to the Institute of Electrical and Electronics Engineers at a conference.
Kent Chojnacki is the manager of NASA’s Systems Engineering & Integration Office. He recently gave a presentation entitled Human Landing System. While it only ran to six content slides, he provided some more details into how the agency is arranging its work with future contractors developing the part of the Artemis program that will take astronauts down to the lunar surface.

SpaceX rapidly stacks Starship and Super Heavy with ‘Mechazilla’
Posted by Genevieve Klien in category: space travel
For the second time ever, SpaceX has used Starbase’s ‘Mechazilla’ tower and arms to stack a Starship upper stage on top of a Super Heavy booster.
This time around, though, SpaceX clearly learned a great deal from its second February 9th Starship stack and was able to complete the stacking process several times faster on March 15th. During the second attempt, depending on how one measures it, it took SpaceX around three and a half hours from the start of the lift to Starship fully resting on Super Heavy. With Stack #3, however, SpaceX was able to lift, translate, lower, and attach Starship to Super Heavy in just over an hour.
Oddly, SpaceX managed that feat without a claw-like device meant to grab and stabilize Super Heavy during stacking operations. For Stack #2, all three arms were fully in play. First, a pair of ‘chopsticks’ – giant arms meant to grab, lift, and even recover Starships and boosters – grabbed Ship 20, lifted it close to 100 meters (~300 ft) above the ground, rotated it over top of Super Heavy, and briefly paused. A third arm – known as the ship quick-disconnect or umbilical arm – swung in and extended its ‘claw’ to grab onto hardpoints located near the top of Super Heavy. Once the booster was secured, the ‘chopsticks’ slowly lowered Ship 20 onto Booster 4’s interstage and six clamps joined the two stages together.

Scientist May Have Found The Secret To Letting Humans BREATHE In Space With Genius Science Trick
Posted by Shane Hinshaw in categories: science, space travel, sustainability
Bacteria might be the solution to all of our space breathing issues. According to Mashable, scientists may use cyanobacteria to figure out how humans might quickly acquire oxygen in space.
Cyanobacteria convert carbon dioxide into oxygen. Cyanobacteria are found in extremely difficult settings on Earth, thus it is predicted that they would be able to live on Mars.
Some scientists have proposed transporting the bacterium to Mars to test whether it can produce oxygen for future people who could end up there. Experiments have previously demonstrated that cyanobacteria can flourish in a Martian environment.

NASA astronaut Mark Vande Hei breaks record for longest US spaceflight
Posted by Genevieve Klien in category: space travel
When NASA astronaut Mark Vande Hei launched into space 11 months ago, he did not know how long he would be off the planet, let alone that he would be up there long enough to set any records.
But when the clock strikes 12:24 p.m. EDT (1624 GMT) today (March 15), Vande Hei will claim the title of the U.S. astronaut with the single longest spaceflight in history. At a mission elapsed time of 340 days, 8 hours and 42 minutes, Vande Hei will surpass the duration logged by NASA astronaut Scott Kelly on March 2, 2013.

Billionaire Space Tourism Has Become Insufferable
Posted by Shubham Ghosh Roy in categories: biotech/medical, climatology, finance, government, space travel, sustainability
Last summer, at a time when the pandemic had strained many people’s finances, inflation was rising and unemployment was still high, the sight of the richest man in the world joyriding in space hit a nerve. On July 20 Amazon founder Jeff Bezos rode to the edge of space onboard a rocket built by his company Blue Origin. A few weeks earlier ProPublica had revealed that he did not pay any income taxes for two years, and in other years he paid a tax rate of just 0.98 percent. To many watching, it rang hollow when Bezos thanked Amazon’s workers, whose low-paid labor had enriched him enough to start his own rocket company, even though Amazon had quashed workers’ efforts to unionize several months before. The fact that another billionaire, Richard Branson, had also launched himself onboard his own company’s rocket just a week earlier did not help.
COVID changed many people’s willingness to shrug off the excesses of the rich. The pandemic drew an impossible-to-ignore distinction between those who can literally escape our world and the rest of us stuck on the ground confronting the ills of Earth: racism, climate change, global diseases. Even several members of Congress expressed their disapproval of Bezos. “Space travel isn’t a tax-free holiday for the wealthy,” said Representative Earl Blumenauer of Oregon. Bezos and Branson putting the spotlight on themselves as passengers served to downplay the work that hundreds of scientists and engineers at Blue Origin and Virgin Galactic had put into designing, building and testing their spacecraft. It also masked the reality that advances in private spaceflight really could eventually pay off in greater access to space for all and more opportunities for scientific research that could benefit everyone. All their flights did was give the impression that space—historically seen as a brave pursuit for the good of all humankind—has just become another playground for the 0.0000001 percent.
