NASA's Atomic Fridge Will Make the ISS the Coldest Known Place in the Universe

NASA's Atomic Fridge Will Make the ISS the Coldest Known Place in the Universe

An anonymous reader shares a report: Later this year, a small part of the International Space Station will become 10 billion times colder than the average temperature of the vacuum of space thanks to the Cold Atom Lab (CAL). Once it’s on the space station, this atomic fridge will be the coldest known place in the universe and will allow physicists to ‘see’ into the quantum realm in a way that would never be possible on Earth. In a normal room, “atoms are bouncing off one another in all directions at a few hundred meters per second,” Rob Thompson, a NASA scientist working on CAL explained in a statement. CAL, however, can reach temperatures that are just one ten billionth of a degree above absolute zero — the point at which matter loses all its thermal energy — which means that this chaotic atomic motion comes to a near standstill. CAL uses magnetic fields and lasers traps to capture the gaseous atoms and cool them to nearly absolute zero. Since all the atoms have the same energy levels at that point, these effectively motionless atoms condense into a state of quantum matter called a Bose-Einstein condensate. This state of matter means that the atoms have the properties of one continuous wave rather discrete particles.

NASA To Pay More For Less Cargo Delivery To the Space Station

NASA To Pay More For Less Cargo Delivery To the Space Station

A new report from NASA’s inspector general, Paul Martin, finds that NASA will pay significantly more for commercial cargo delivery to the ISS in the 2020s rather than enjoying cost savings from maturing systems. “NASA will likely pay $400 million more for its second round of delivery contracts from 2020 to 2024 even though the agency will be moving six fewer tons of cargo,” reports Ars Technica. “On a cost per kilogram basis, this represents a 14-percent increase.” From the report: One of the main reasons for this increase, the report says, is a 50-percent increase in prices from SpaceX, which has thus far flown the bulk of missions for NASA’s commercial cargo program with its Dragon spacecraft and Falcon 9 rocket. This is somewhat surprising because, during the first round of supply missions, which began in 2012, SpaceX had substantially lower costs than NASA’s other partner, Orbital ATK. SpaceX and Orbital ATK are expected to fly 31 supply missions between 2012 and 2020, the first phase of the supply contract. Of those, the new report states, SpaceX is scheduled to complete 20 flights at an average cost of $152.1 million per mission. Orbital ATK is scheduled to complete 11 missions at an average cost of $262.6 million per mission.

But that cost differential will largely evaporate in the second round of cargo supply contracts. For flights from 2020 to 2024, SpaceX will increase its price while Orbital ATK cuts its own by 15 percent. The new report provides unprecedented public detail about the second phase of commercial resupply contracts, known as CRS-2, which NASA awarded in a competitively bid process in 2016. SpaceX and Orbital ATK again won contracts (for a minimum of six flights), along with a new provider, Sierra Nevada Corp. and its Dream Chaser vehicle. Bids by Boeing and Lockheed Martin were not accepted.

Bigelow Launching New Company To Sell Private Space Stations

Bigelow Launching New Company To Sell Private Space Stations

hyperclocker shares a report from Popular Mechanics: The future of spacecraft in lower Earth orbit (LEO) looks to be an increasingly commercial affair. Bigelow Aerospace, a Las Vegas-based company that builds livable space habitats, has now created a spinoff company known as Bigelow Space Operations (BSO). BSO will market and operate any space habitats that Bigelow sells. The creation of BSO signals that Bigelow is preparing for a future of commercial space living. Recently leaked NASA documents show that the Trump Administration wants to convert the International Space Station into a commercial venture, and BSO is betting that businesses including private scientific ventures and hotels will be interested in creating a profit above the Earth. A prototype Bigelow habitat, the Bigelow Expandable Activity Module (BEAM), has been connected to the ISS since 2016. It’s proven such a successful addition that last year NASA extended its contract for an additional three years. But Bigelow is thinking past the BEAM. In its press release announcing BSO, it highlights its planned launches of the B330-1 and B330-2, spacecraft with 6-person capacity, in 2021.

The Trump Administration is Moving To Privatize the International Space Station: Report

The Trump Administration is Moving To Privatize the International Space Station: Report

The Trump administration is planning to privatize the international space station instead of simply decommissioning the orbiting international experiment in 2024, The Washington Post reports. From a report: According to a document obtained by the Post, the current administration is mulling handing the International Space Station off to private industry instead of de-orbiting it as NASA “will expand international and commercial partnerships over the next seven years in order to ensure continued human access to and presence in low Earth orbit.” The Post also reported that the administration was looking to request $150 million in fiscal year 2019 “to enable the development and maturation of commercial entities and capabilities which will ensure that commercial successors to the ISS — potentially including elements of the ISS — are operational when they are needed.” The U.S. government has already spent roughly $100 billion to build and operate the space station as part of an international coalition that also includes the European Space Agency, the Japan Aerospace Exploration Agency, and the Russian Space Agency.

No One Knows What To Do With the International Space Station

No One Knows What To Do With the International Space Station

An anonymous reader shares a report: In 2024 the clock will run out on the International Space Station. Maybe. That’s the arbitrary deadline that Congress imposed back in 2014, at which point they’ll have to decide whether or not to keep funding the ISS. And yeah, that’s a whole seven years away. But then again…it’s only seven years away. The ISS takes up half of NASA’s human exploration budget — half of the pile of money allotted for things like sending humans to Mars or to an asteroid. And if they want to push further into space exploration, NASA can’t keep sinking three to four billion dollars a year into the ISS. Not that it’s really their decision. Congress — specifically the House Committee on Science, Space, and Technology — decides how much money NASA will get. And because politicians aren’t experts in space travel, they keep holding hearings to discuss what they could possibly do with the ISS in seven years’ time. Let private industry take it over? Let it crash and burn into the South Pacific? Let the program keep running? The latest hearing took place last week. These are hard questions, in part because people have very different opinions on what’s valuable about NASA, and therefore about whether the ISS is still useful. Maybe you think that NASA should really be about exploration, about pushing the boundaries of what we know and where we can travel. In that case, the ISS might not be your first priority. That’s a huge chunk of the budget that goes toward bringing things back and forth to low Earth orbit instead of venturing to other planets.

17-Year-Old Corrects NASA Mistake In Data From The ISS

17-Year-Old Corrects NASA Mistake In Data From The ISS

“A British teenager has contacted scientists at NASA to point out an error in a set of their own data,” writes the BBC. An anonymous reader quotes their report.

A-level student Miles Soloman found that radiation sensors on the International Space Station (ISS) were recording false data… The correction was said to be “appreciated” by NASA, which invited him to help analyse the problem… The research was part of the TimPix project from the Institute for Research in Schools (IRIS), which gives students across the UK the chance to work on data from the space station, looking for anomalies and patterns that might lead to further discoveries. What Miles had noticed was that when nothing hit the detector, a negative reading was being recorded. But you cannot get negative energy… It turned out that Miles had noticed something no-one else had — including the NASA experts. NASA said it was aware of the error, but believed it was only happening once or twice a year. Miles had found it was actually happening multiple times a day.

There’s a video of the student — and his teacher — describing the discovery, a story which Miles says his friends at high school listen to with “a mixture of jealousy and boredom”
