Science-Heavy SpaceX Dragon Headed to Space Station

Heads up: a new batch of science is headed to the International Space Station aboard the SpaceX Dragon on April 2, 2018. Launching from Florida’s Cape Canaveral Air Force Station atop a Falcon 9 rocket, this fire breathing (well, kinda…) spacecraft will deliver science that studies thunderstorms on Earth, space gardening, potential pathogens in space, new ways to patch up wounds and more.

Let’s break down some of that super cool science heading 250 miles above Earth to the orbiting laboratory:

Sprites and Elves in Space

Atmosphere-Space Interactions Monitor (ASIM) experiment will survey severe thunderstorms in Earth’s atmosphere and upper-atmospheric lightning, or transient luminous events. 

These include sprites, flashes caused by electrical break-down in the mesosphere; the blue jet, a discharge from cloud tops upward into the stratosphere; and ELVES, concentric rings of emissions caused by an electromagnetic pulse in the ionosphere.

Here’s a graphic showing the layers of the atmosphere for reference:

Metal Powder Fabrication

Our Sample Cartridge Assembly (MSL SCA-GEDS-German) experiment will determine underlying scientific principles for a fabrication process known as liquid phase sintering, in microgravity and Earth-gravity conditions.

Science term of the day: Liquid phase sintering works like building a sandcastle with just-wet-enough sand; heating a powder forms interparticle bonds and formation of a liquid phase accelerates this solidification, creating a rigid structure. But in microgravity, settling of powder grains does not occur and larger pores form, creating more porous and distorted samples than Earth-based sintering. 

Sintering has many applications on Earth, including metal cutting tools, automotive engine connecting rods, and self-lubricating bearings. It has potential as a way to perform in-space fabrication and repair, such as building structures on the moon or creating replacement parts during extraterrestrial exploration.

Plants in space! It’s l[a]unch time!

Understanding how plants respond to microgravity and demonstrating reliable vegetable production in space represent important steps toward the goal of growing food for future long-duration missions. The Veggie Passive Orbital Nutrient Delivery System (Veggie PONDS) experiment will test a passive nutrient delivery system in the station’s Veggie plant growth facility by cultivating lettuce and mizuna greens for harvest and consumption on orbit.

The PONDS design features low mass and low maintenance, requires no additional energy, and interfaces with the Veggie hardware, accommodating a variety of plant types and growth media.

Testing Materials in Space

The Materials ISS Experiment Flight Facility (MISSE-FF) experiment will provide a unique platform for testing how materials, coatings and components react in the harsh environment of space.

A continuation of a previous experiment, this version’s new design eliminates the need for astronauts to perform spacewalks for these investigations. New technology includes power and data collection options and the ability to take pictures of each sample on a monthly basis, or more often if required. The testing benefits a variety of industries, including automotive, aeronautics, energy, space, and transportation.

New Ways to Develop Drugs in Space

Microgravity affects movement and effectiveness of drugs in unique ways. Microgravity studies already have resulted in innovative medicines to treat cancer, for example. The Metabolic Tracking investigation determines the possibility of developing improved drugs in microgravity, using a new method to test the metabolic impacts of drug compounds. This could lead to more effective, less expensive drugs.

Two Steps Forward in the Search for Life on Mars

We haven’t found aliens but we are a little further along in our search for life on Mars thanks to two recent discoveries from our Curiosity Rover.

We detected organic molecules at the harsh surface of Mars! And what’s important about this is we now have a lot more certainty that there’s organic molecules preserved at the surface of Mars. We didn’t know that before.

One of the discoveries is we found organic molecules just beneath the surface of Mars in 3 billion-year-old sedimentary rocks.

Second, we’ve found seasonal variations in methane levels in the atmosphere over 3 Mars years (nearly 6 Earth years). These two discoveries increase the chances that the record of habitability and potential life has been preserved on the Red Planet despite extremely harsh conditions on the surface.

Both discoveries were made by our chem lab that rides aboard the Curiosity rover on Mars.

Here’s an image from when we installed the SAM lab on the rover. SAM stands for “Sample Analysis at Mars” and SAM did two things on Mars for this discovery.

One - it tested Martian rocks. After the arm selects a sample of pulverized rock, it heats up that sample and sends that gas into the chamber, where the electron stream breaks up the chemicals so they can be analyzed.

What SAM found are fragments of large organic molecules preserved in ancient rocks which we think come from the bottom of an ancient Martian lake. These organic molecules are made up of carbon and hydrogen, and can include other elements like nitrogen and oxygen. That’s a possible indicator of ancient life…although non-biological processes can make organic molecules, too.

The other action SAM did was ‘sniff’ the air.

When it did that, it detected methane in the air. And for the first time, we saw a repeatable pattern of methane in the Martian atmosphere. The methane peaked in the warm, summer months, and then dropped in the cooler, winter months.

On Earth, 90 percent of methane is produced by biology, so we have to consider the possibility that Martian methane could be produced by life under the surface. But it also could be produced by non-biological sources. Right now, we don’t know, so we need to keep studying the Mars!

One of our upcoming Martian missions is the InSight lander. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the “inner space” of Mars: its crust, mantle, and core.

Finding methane in the atmosphere and ancient carbon preserved on the surface gives scientists confidence that our Mars 2020 rover and ESA’s (European Space Agency’s) ExoMars rover will find even more organics, both on the surface and in the shallow subsurface.
