Could We Put Data Centers In Space?

Universe Today - Fri, 06/21/2024 - 11:45am

Artificial intelligence has taken the world by storm lately. It also requires loads of band-end computing capability to do the near-miraculous things that it does. So far, that “compute,” as it’s known in the tech industry, has been based entirely on the ground. But is there an economic reason to do it in space? Some people seem to think so, as there has been a growing interest in space-based data centers. Let’s take a look at why.

Space-based data centers have several advantages over ground-based ones. The first and most obvious is the near-unlimited amount of space in space. Second, there are plenty of potential options for novel power and cooling technologies that can’t exist back on Earth. Third, using a space-based data center as a relay point for information could cut down on lag in data transfer between continents. Let’s look at each in turn.

One of the significant constraints for data centers is space – they require large amounts of it, and it is expensive in the areas where they are most needed (i.e., next to large population centers). The tech giants have massive budgets associated with real estate for data centers, and that amount will only continue to grow as their computational requirements increase. On the other hand, building a modular data center in space, with each launch adding additional computing power, is a reasonable way to infinitely expand a company’s hardware resources without the constraint of a physical location.

OrbitsEdge is a start-up company focusing on building space-based data centers. Here’s a video describing their business model.

Data centers would also have access to novel power and cooling technologies in space. They could utilize solar panels directly attached to them to harness unlimited green energy, and ones in a high enough orbit could be powered effectively all the time, no matter weather conditions or Earth’s rotation. Power satellites run off a similar idea, and the underlying technology is already there; it hasn’t been applied to this use case yet.

Many data centers also use water cooling systems. While water is heavy and expensive to launch into orbit, plenty of asteroids have enough water on them to supply millions of data centers with all the cooling they need. A recent paper from researchers in South Africa looked at this process and found several asteroids with relatively close trajectories that could supply orbiting data centers with enough water to last centuries.

Space-based data centers could also allow for fast transmission between two points on the globe without sending data over a complicated path from one continent to another. Directly linking two computers is easier if they have a line of sight to the same relay point, such as a data center floating around the Earth. Using that data center to relay information between the two, similar to what Starlink currently does with satellite internet technology, would solve latency problems between far-away locations.

But there are also some hurdles. Data transfer rates on satellites aren’t up to speed with modern ground-based technologies, though that is consistently improving every year thanks to efforts like Starlink. Getting the hardware into orbit poses an obvious challenge and expense. However, that bar might be better lower with the continual development of Starship and its low-cost launch capability. Finally, coordinating across different governments, especially regarding wireless bandwidth, can be tricky, but without that coordination, the ability to talk across borders is severely limited.

None of those limitations are insurmountable; technologists and investors seem to realize that. As our own Alan Boyle reported in March, a company called Lumen Orbit raised $2.4 million only three months after being founded to bring data centers to space. Axiom Space, which we’ve mentioned in several articles in the last few years, is also partnering with Kepler Space and Skyloom to develop the world’s first functional space-based data center.

With this increased interest, it seems only a matter of time before some of the computing power that is enabling the AI and computing revolution makes its way into orbit. But for now, the question remains: who will be the first one to do it?

Coordinating an Airborne Lab Across the Globe with NASA’s Earth Science Project Office

NASA - Breaking News - Fri, 06/21/2024 - 11:25am

Tracking the spread of harmful air pollutants across large regions requires aircraft, satellites, and diverse team of scientists. NASA’s global interest in the threat of air pollution extends into Asia, where it works with partners on the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ).  This international mission integrates satellite data and aircraft measurements with local air quality ground monitoring and modeling efforts across Asia.

Orchestrating a mission of this scale requires complicated agreements between countries, the coordination of aircraft and scientific instrumentation, and the mobilization of scientists from across the globe. To make this possible, ARC’s Earth Science Project Office (ESPO) facilitated each phase of the campaign, from site preparation and aircraft deployment to sensitive data management and public outreach.

“Successfully meeting the ASIA-AQ mission logistics requirements was an incredible effort in an uncertainty-filled environment and a very constrained schedule to execute and meet those requirements,” explains ASIA-AQ Project Manager Jhony Zavaleta. “Such effort drew on the years long experience on international shipping expertise, heavy equipment operations, networking and close coordination with international service providers and all of the U.S. embassies at each of our basing locations.”

Understanding Air Quality Globally

ASIA-AQ benefits our understanding of air quality and the factors controlling its daily variability by investigating the ways that air quality can be observed and quantified. The airborne measurements collected during the campaign are directly integrated with existing satellite observations of air quality, local air quality monitoring networks, other available ground assets, and models to provide a level of detail otherwise unavailable to advance understanding of regional air quality and improve future integration of satellite and ground monitoring information.

ESPO’s Mission-Critical Contributions

  • Facilitating collaboration between governmental agencies and the academic community by executing project plans, navigating bureaucratic hurdles, and consensus building.
  • Mission planning for two NASA aircraft. AFRC DC-8 completed 16 science flights, totaling 125 flight hours. The LaRC GIII completed 35 science flights, totaling 157.7 flight hours.
  • Enabling international fieldwork and workforce mobilization by coordinating travel, securing authorizations and documentation, and maintaining relationships with local research partners.
  • Managing outreach to local governments and schools. ASIA-AQ team members showcased tools used for air quality science to elementary/middle/high school students. Recent news feature here.

The flying laboratory of NASA’s DC-8

NASA flew its DC-8 aircraft, picture above, equipped with instrumentation to monitor the quality, source, and movement of harmful air pollutants. Scientists onboard used the space as a laboratory to analyze data in real-time and share it with a network of researchers who aim to tackle this global issue.

“Bringing the DC-8 flying laboratory and US researchers to Asian countries not only advances atmospheric research but also fosters international scientific collaboration and education,” said ESPO Project Specialist Vidal Salazar. “Running a campaign like ASIA AQ also opens doors for shared knowledge and exposes local communities to cutting-edge research.”

Fostering Partnerships Through Expertise and Goodwill

International collaboration fostered through this campaign contributes to an ongoing dialogue about air pollution between Asian countries.

“NASA’s continued scientific and educational activities around the world are fundamental to building relationships with partnering countries,” said ESPO Director Marilyn Vasques. “NASA’s willingness to share data and provide educational opportunities to locals creates goodwill worldwide.”

The role of ESPO in identifying, strategizing, and executing on project plans across the globe created a path for multi-sectoral community engagement on air quality. These global efforts to improve air quality science directly inform efforts to save lives from this hazard that affects all.

The JWST Peers into the Heart of Star Formation

Universe Today - Fri, 06/21/2024 - 9:51am

The James Webb Space Telescope has unlocked another achievement. This time, the dynamic telescope has peered into the heart of a nearby star-forming region and imaged something astronomers have longed to see: aligned bipolar jets.

JWST observing time is in high demand, and when one group of researchers got their turn, they pointed the infrared telescope at the Serpens Nebula. It’s a young, nearby star-forming region known for being the home of the famous Pillars of Creation. (The Hubble Space Telescope made the pillars famous, and the JWST followed that up with its own stunning image.)

But these researchers weren’t focusing on the Pillars. As a nearby star-forming region, Serpens Nebula is a natural laboratory to study how stars form and to try to answer some outstanding questions about the process. The JWST delivered.

A team of astronomers from the USA, India, and Taiwan examined the region and published their results in a paper titled “Why are (almost) all the protostellar outflows aligned in Serpens Main?” The lead author is Joel Green from the Space Science Telescope Institute.

Stars form when Giant Molecular Clouds of hydrogen collapse. They start out as protostars, objects that haven’t begun fusion yet and are still acquiring mass. As they grow, gas from the cloud gathers in a swirling accretion ring around the star. As it moves, the gas heats up and emits light.

As the cloud collapses into a protostar, some of the energy is converted into angular momentum and the young star spins. For the young star to keep acquiring mass, some of the spin needs to be removed. That happens as the swirling accretion disk emits some of the gas from bipolar jets, also called protostellar outflows. They’re part of how stars regulate themselves as they grow, and they come from the young star’s poles, perpendicular to the spin. The magnetic fields around the star drive the jets out of the poles.

But there’s a lot more detail in the process and some outstanding questions. Stars don’t form in isolation; they usually form in clusters or groups, and there are intermingling magnetic fields at work. At only 1300 light-years away, Serpens Nebula is a good place to try to spy some of this detail. Until the JWST came along, the detail was hidden from even our most powerful telescopes, and astrophysicists were left to theorize with what they could observe.

“Star formation is thought to be partly regulated by magnetic fields with coherence scales of a few parsecs – smaller than Giant Molecular Clouds, but larger than individual protostars,” the authors write in their paper. “Magnetic fields likely play a key role in the collapse of cloud cores distributed in elongated structures called filaments.”

Cloud cores are the precursors to star clusters, and the filaments are filaments of gas inside giant molecular clouds. Cloud cores cluster along these filaments where the gas density is higher. Much of what goes inside these environments is shrouded by gas and dust, so theories were based on what astronomers were able to observe prior to the JWST.

“While theory often assumes idealized alignment of protostellar disks, cores, and associated magnetic fields, feedback may lead to misalignment on the smallest scales (1000 au) as the protostar evolves,” the authors write. To understand what happens when protostars form in these environments, astrophysicists wanted to know if the angular momentum in a group of stars that form together correlates with each other and with the magnetic field of the filament they form in.

The key to understanding this is the protostellar jets that come from young protostars since their direction is governed by magnetic fields. Protostellar outflows are a signature of young, still-forming stars, and when these outflows collide with the surrounding gas, they create “striking structures of shocked ionized, atomic, and molecular gas,” the authors write.

“Since the jets are likely accelerated and collimated by a rapidly rotating poloidal magnetic field in the inner star-disk system, they emerge along the stellar rotation axis and thus trace the angular momentum vector of the star itself,” the authors explain.

That leads us to the significance of the new JWST image of Serpens Nebula. The researchers found a group of young protostars in the Serpens Nebula with aligned jets. These stars are only about 100,000 years old, making them desirable observational targets in the effort to understand star formation.

This image from the NASA/ESA/CSA James Webb Space Telescope shows a portion of the Serpens Nebula, where astronomers have discovered a grouping of aligned protostellar outflows. These jets are signified by bright, clumpy streaks that appear red, which are shock waves from the jet hitting surrounding gas and dust. Here, the red colour represents the presence of molecular hydrogen and carbon monoxide. Image Credit: NASA, ESA, CSA, STScI, K. Pontoppidan (NASA’s Jet Propulsion Laboratory), J. Green (Space Telescope Science Institute)

The jets in a group of young protostars are usually misaligned. Previous research, including research based on JWST images, found only misaligned jets among groups of stars in the same clusters and clouds. Many things can misalign the jets in associated stars, but the outstanding question is if stars that form together start out with the same magnetic field alignment.

Webb found something different in the Serpens Nebula. The telescope found a group of 12 protostars whose jets are lined up with the magnetic field of the filament they formed in.

“The axes of the 12 outflows in the NW region are inconsistent with random orientations and align with the filament direction from NW to SE,” the researchers write in their paper. They say the probability of this happening randomly is extremely low. “We estimate <0.005% probability of the observed alignments if sampled from a uniform distribution in position angle,” they write.

The stars along the filament in the northwest region are aligned, but stars along other filaments in other regions of Serpens are not aligned.

“It appears that star formation proceeded along a magnetically confined filament that set the initial spin for most of the protostars,” the authors write in their conclusion. “We hypothesize that in the NW region, which may be younger, the alignment is preserved, whereas the spin axes have had time to precess or dissociate through dynamic interactions in the SE region.”

The JWST needed only two NIRCam images of the Serpens Nebula to answer a question that’s foundational to star formation. Its work won’t end here.

“We anticipate more detailed studies of star-forming filaments with JWST in the future,” the authors conclude.
