		<description><![CDATA[Boeing Reportedly Looking to Sell Off Its Disastrous Starliner Spacecraft
https://futurism.com/the-byte/boeing-sell-off-starliner

Embattled aerospace giant Boeing is reportedly looking to sell off its space business following the disastrous crewed test launch of its much-maligned Starliner that left two NASA astronauts stranded in space.

As the Wall Street Journal reports, insider sources claim that Boeing is looking to get out of the space race altogether in the face of a deepening financial crisis — a startling about-face for a company that&#039;s worked on iconic space vehicles ranging from NASA&#039;s Space Shuttle to the International Space Station.

Despite a decade of development, Boeing has yet to successfully deliver and return astronauts on board its Starliner capsule, a damning indictment of a company that already has several major fires to put out.

In other words, it shouldn&#039;t come as a surprise that Boeing is looking to cut its losses — but buyer beware.]]></description>

		<description><![CDATA[Boeing Might Not Get Starliner Working Before the Space Station Is Destroyed
https://futurism.com/the-byte/boeing-starliner-working-before-space-station-destroyed

Boeing could quickly run out of time.
Clock Ticking
Over the weekend, NASA officially decided that it was too risky to return its two stranded astronauts Sunita Williams and Butch Wilmore on board Boeing&#039;s plagued Starliner.

The decision came as a massive blow to Boeing. After many years of development, the company still doesn&#039;t have a successful crewed test flight under its belt.

And whether the much-maligned capsule will ever be able to deliver and safely return a crew to and from the International Space Station remains an open question.

That&#039;s because NASA is already planning to decommission the orbital outpost in 2030 with SpaceX&#039;s help, giving Boeing roughly five years to get its act together — and it&#039;s already been around five years since the company&#039;s failed uncrewed test flight.

Harrison told NPR that he thinks it&#039;s &quot;fairly likely&quot; that Boeing may choose to &quot;step back&quot; from Starliner &quot;within a few weeks or months.&quot;

&quot;This program kind of sticks out as something that doesn&#039;t fit with the rest of their business,&quot; he added.

Boeing has already lost a staggering $1.6 billion on the development of Starliner. That&#039;s on top of getting more than $4 billion worth of funding through NASA&#039;s Commercial Crew Program in 2014.

Meanwhile, SpaceX has done far more with far less funding from the space agency, having completed just shy of a dozen crewed missions to the ISS.

One way to look at the situation is that NASA would have been out of luck if it weren&#039;t for the fact that it signed up both SpaceX and Boeing to develop spacecraft.

&quot;If they had only selected one provider, it would have been Boeing, because SpaceX was the risky prospect at the time,&quot;]]></description>

		<description><![CDATA[Astronauts Stranded With No Set Return Date For New Boeing Starliner
https://www.sciencealert.com/astronauts-stranded-with-no-set-return-date-for-new-boeing-starliner

After helium leaks and thruster problems with Boeing&#039;s Starliner capsule, NASA has been pushing back the return date from the International Space Station.

On Friday, the agency announced they no longer had a planned return date. Instead, they will keep testing the capsule, trying to understand its issues, and seeing if they can make any fixes. Plenty of supplies are on the station, so there&#039;s no urgent need to bring the two astronauts back to Earth.]]></description>

		<description><![CDATA[It’s official — Florida man Alejandro Otero won the cosmic lottery last month as NASA confirms the object that crashed through his roof in March was indeed from the ISS. Granted, there wasn’t much left of the 2,360 kg battery pack by the time it hit the Otero residence in the Gulf Coast town of Naples — just a 0.7-kg metal cylinder. NASA had expected the entire nickel hydride pack, tossed overboard in March of 2021 in favor of lithium batteries, would burn up upon reentry. That ended up being optimistic, and perhaps foreseeable since the surviving fragment was made from inconel, an alloy specifically used in applications involving high temperatures — perhaps not reentry hot, but still. It seems like Otero just wants to get NASA to pay for the repairs to his house, but honestly, if something like that crashes through our roof, we’re just going to fix it ourselves and shut up so we can keep the thing.

The current cost of resupplying the ISS is around $80,000 per kg, although this price has varied over the years. (references)

The pressurized volume of air on the ISS is 1,005.0 m3
(ref). As the density of air is 1.293 kg/m3

, this equates to 1300 kg, or 104 million USD worth of air, after considering the launch costs. So, certainly far from free!

The oxygen (O₂) in the air is consumed by the astronauts on the station, converting O₂ into CO₂. Some of the CO₂ can be converted back into O₂ but this process isn&#039;t 100% efficient. So replacement O₂ needs to be sent up on ISS resupply missions.

Each crew member requires about two pounds per day of oxygen, which is 14 pounds for a crew of seven, 6.35029 kg per day, 2318 kg per year, or roughly 29.2 million USD worth of O₂ per year, at current resupply costs, if no CO₂ was recycled.

However, the O₂ is sent up as water (H₂O), which makes it heavier by a factor of (18/16 = 1.125).
