NASA has another cargo shipment en route to the International Space Station following a successful Falcon 9 launch of SpaceX’s 27th resupply mission for the agency.

Carrying more than 6,200 pounds of science experiments, crew supplies, and other cargo, the SpaceX Dragon spacecraft was launched to the space station by a Falcon 9 rocket at 8:30 p.m. EDT Tuesday from NASA’s Kennedy Space Center in Florida.

The cargo spacecraft is scheduled to autonomously dock with the space station at 7:52 a.m. EDT Thursday, March 16, and remain at the station for about 30 days. Coverage of arrival will begin at 6:15 a.m. EDT on NASA Television, the agency’s website, and the NASA app.

Among the science experiments Dragon is delivering to the space station for NASA and its partners are:

3D Heart Cells, Tissue

The first Cardinal Heart investigation conducted aboard the space station showed that four weeks of microgravity exposure can cause significant changes in heart cell function and gene expression. Researchers concluded that these changes could lead to long-term medical issues. The Cardinal Heart 2.0 experiment builds on these results, using heart organoids, 3D structures made up of all the different types of cells, to test whether clinically approved drugs reduce these microgravity-induced changes in heart cell function. Results could support the development of effective drug combinations to improve the health of astronauts and patients on Earth.

The Engineered Heart Tissues-2 study continues work with 3D cultured cardiac muscle tissue to assess human cardiac function in microgravity. Previous work with 3D cultures in space detected changes at the cellular and tissue level that could provide early indication of the development of cardiac disease. This investigation tests whether new therapies prevent these adverse spaceflight effects from occurring. The model used in this study has potential use in drug development and other applications related to diagnosing and treating cardiac dysfunction on Earth.

Cardinal Heart 2.0 and Engineered Heart Tissues-2 are the final two experiments comprising the National Institutes for Health and International Space Station National Lab’s Tissue Chips in Space initiative. Researchers hope to learn more about the impact of microgravity on human health and disease, and translate that understanding to improved human health on Earth.

Student Ball Clamp Monopod Project

NASA’s HUNCH (High school students United with NASA to Create Hardware) program enables students to fabricate real-world products for NASA as they apply their science, technology, engineering, and mathematics skills. The HUNCH Ball Clamp Monopod attempts to address astronaut comments on the difficulty of positioning video or still cameras in the middle of a module. The student-manufactured project is composed of an aluminum monopod fitted with a camera shoe and ball clamp that can be attached to a standard space station handrail. The ball clamp serves as a pivoting platform for photography and video.

Liquid Life Support Systems

Because microgravity makes it difficult to control the flow of liquids, the space station has been unable to take advantage of carbon dioxide removal methods that use specialized liquids. Liquid-based carbon dioxide removal systems such as those on submarines offer higher efficiency than other types of systems. The CapiSorb Visible System study demonstrates liquid control using capillary forces, the interaction of a liquid with a solid that can draw a fluid up a narrow tube, which are characteristic of liquids that can absorb carbon dioxide. This is an important consideration for future longer-duration space missions where improved efficiency will support crews over many months or years.

Bacterial Biofilms

Microbial biofilms are combinations of microorganisms that embed themselves in a self-produced slimy matrix. Biofilms are of concern for spaceflight because they can cause damage to equipment, are resistant to cleaning agents, and can harbor microorganisms that might cause infections. The ESA (European Space Agency) Biofilms investigation studies bacterial biofilm formation and antimicrobial properties of different metal surfaces under spaceflight conditions. Antimicrobial surfaces that can inhibit biofilm growth, such as copper and its alloys with and without laser surface treatment, are used in this study. This project provides additional information to help develop suitable antimicrobial surfaces for future spacecraft.

Lifeform Origins, Survival
An investigation from JAXA (Japan Aerospace Exploration Agency) known as Tanpopo-5 could provide insight into whether terrestrial life can survive in space and help scientists understand the key ingredients that sparked life on Earth. The experiment studies the response to space exposure in radiation-resistant microbes, moss spores, and biochemical compounds including amino acids. Amino acids have been detected in extraterrestrial bodies such as meteorites and are possible precursors to life on Earth. Tanpopo-5 follows four earlier experiments which could all inform strategies to protect other planets from contamination by humans and for returning samples from other planets safely to Earth.

These are just a few of the hundreds of investigations currently conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars.

On March 23, 2023, a geomagnetic storm on the sun caused a stunning display of the Aurora Borealis to be visible as far south as New Mexico, Arizona, Oklahoma, and Virginia. The Northern Lights, a natural phenomenon caused by charged particles from the sun interacting with the Earth’s magnetic field, are usually only visible in the far north. However, this storm caused a rare opportunity for those in more southern regions to witness the incredible light show.

Economics expert explains how consumer price reports show ‘inflation is not done yet’

The statistics from these reports have economists predicting that the Federal Reserve will continue to raise interest rates to get inflation under control.

Published

on

Expectations that inflation has eased fueled recent stock market gains, but results from two major price-tracking indexes came in higher than expected, dousing that optimism with cold water. The statistics from these reports have economists predicting that the Federal Reserve will continue to raise interest rates to get inflation under control.

 “The latest figures underscore the risks of persistently high inflation. Much of the easing that was celebrated at the end of last year has been erased,” said David Bieri, an economics professor for Virginia Tech’s School of Public and International Affairs. He answered a few questions about the persistence of inflation and the Federal Reserve’s efforts to reverse it. 

 Q: What is the difference between the Consumer Price Index (CPI) and the Personal Consumption Expenditures Price Index (PCE)?

“The CPI is a measure of the average change over time in the prices paid by urban consumers for a basket of goods and services. This basket includes commonly purchased items such as food, housing, clothing, transportation, and medical care. The rate of inflation (or deflation) is then inferred by comparing the price of this basket to a base period. The PCE is the one used by the Federal Reserve. Unlike the CPI, the PCE measures not just goods and services for urban consumers, but the prices of all goods and services purchased by households. While the CPI uses a fixed basket of goods and services, the PCE uses a changing basket of goods and services that reflects consumers’ evolving spending patterns. Also, the PCE incorporates data on the quality of goods and services.” 

Q: What can be deduced about inflation and the economy from these new statistics? 

“Different components of the indexes react to different influences of the economic process, and they also do so at different speeds, or as economists like to say, with different lags. For example, fuel and gas prices react with very little delay and if the price of crude oil goes up, it does not take long for these effects to show up. But this is not the case for other important components. Quite a bit of the recent uptick in inflation has to do with the fact that it has taken so long for the post-COVID related upswing in housing to show up in the data. As for the most recent PCE numbers, these were unexpected and point in the direction of more entrenched inflation.  In other words, inflation is not done yet.”

Q: What do these results indicate about the Federal Reserve’s efforts to curb inflation?

“The Fed has to be patient. If we take the image of interest rates working like a brake pedal, the Fed is driving a car on a windy road with a blacked-out windscreen and when it brakes, it can only guess how soon the car — that is, the economy — will slow down, let alone by how much and when the next bend will be. However, the Fed has one key trick up its sleeve: unlike the hapless driver of our car, the Fed can influence how many bends in the road might show up in the future. It does this by something that we call ‘forward guidance,’ which is a wonky term for how the Fed’s attempts influence consumer and market expectations of consumers and market participants. Essentially the Fed is saying that if we stop believing there will be inflation in the future, there actually won’t be any.”
