Hunting for Organic Molecules on Mars

Did Mars once have life? To help answer that question, an international team of scientists created an incredibly powerful miniature chemistry laboratory, set to ride on the next Mars rover.

The instrument, called the Mars Organic Molecule Analyzer Mass Spectrometer (MOMA-MS), will form a key part of the ExoMars Rover, a joint mission between the European Space Agency (ESA) and Roscosmos. A mass spectrometer is crucial to send to Mars because it reveals the elements that can be found there. A Martian mass spectrometer takes a sample, typically of powdered rock, and distinguishes the different elements in the sample based on their mass.

After 8 years of designing, building, and testing, NASA scientists and engineers from NASA’s Goddard Space Flight Center said goodbye to their tiny chemistry lab and shipped it to Italy in a big pink box. Building a tiny instrument capable of conducting chemical analysis is difficult in any setting, but designing one that has to launch on a huge rocket, fly through the vacuum of space, and then operate on a planet with entirely different pressure and temperature systems? That’s herculean. And once on Mars, MOMA has a very important job to do. NASA Goddard Center Director Chris Scolese said, “This is the first intended life-detecting instrument that we have sent to Mars since Viking.”

The MOMA instrument will be capable of detecting a wide variety of organic molecules. Organic compounds are commonly associated with life, although they can be created by non-biological processes as well. Organic molecules contain carbon and hydrogen, and can include oxygen, nitrogen, and other elements.

To find these molecules on Mars, the MOMA team had to take instruments that would normally occupy a couple of workbenches in a chemistry lab and shrink them down to roughly the size of a toaster oven so they would be practical to install on a rover.

MOMA-MS, the mass spectrometer on the ExoMars rover, will build on the accomplishments from the Sample Analysis at Mars (SAM), an instrument suite on the Curiosity rover that includes a mass spectrometer. SAM collects and analyzes samples from just below the surface of Mars while ExoMars will be the first to explore deep beneath the surface, with a drill capable of taking samples from as deep as two meters (over six feet). This is important because Mars’s thin atmosphere and spotty magnetic field offer little protection from space radiation, which can gradually destroy organic molecules exposed on the surface. However, Martian sediment is an effective shield, and the team expects to find greater abundances of organic molecules in samples from beneath the surface.

On completion of the instrument, MOMA Project Scientist Will Brinckerhoff praised his colleagues, telling them, “You have had the right balance of skepticism, optimism, and ambition. Seeing this come together has made me want to do my best.”

In addition to the launch of the ESA and Roscosmos ExoMars Rover, in 2020, NASA plans to launch the Mars 2020 Rover, to search for signs of past microbial life. We are all looking forward to seeing what these two missions will find when they arrive on our neighboring planet.

6 Tiny Satellites That Are Changing How We See Earth

HARP: Hyper-Angular Rainbow Polarimeter

What’s better than taking a picture of a cloud to figure out its size and shape? Taking a bunch of pictures all around it. That way you get a three-dimensional view without having to worry about missing something. The HARP CubeSat is going to do just that: make observations of cloud droplets and tiny airborne particles like soot and dust with a modified camera lens from multiple angles. This will give us a full rendering of what’s going on inside the clouds, specifically, how those airborne particles act as “seeds” for water vapor to condense on and form cloud droplets. Since so many of those particles are in the air as a result of man-made pollution, we want to understand how they may be affecting clouds, weather and climate.

RAVAN: Radiometer Assessment using Vertically Aligned Nanotubes

Anyone who’s worn a black shirt on a summer day knows how much sunlight and heat it absorbs. The RAVAN 3-unit CubeSat, however, carries “blacker than black” technology – carbon nanotubes set up like a bundle of drinking straws that suck up nearly all the sunlight and energy that reach them to the point that your black shirt seems merely dark grey in comparison. Flying in low Earth orbit, RAVAN’s super sensitive instrument will detect tiny changes in the amount of sunlight and energy passing into and out of the top of the atmosphere. The amount of energy passing through the top of the atmosphere is where the net accounting of Earth’s energy budget happens – one of the major measurements we need in order to understand the effects of greenhouse gases on global warming and climate change. 

MiRaTA: Microwave Radiometer Technology Acceleration

That long skinny piece coming out of the bottom right side under the solar panel? That’s a measuring tape. It’s doubling as a communications antenna on the MiRaTA CubeSat that will be a mini-weather station in space. This 3-unit, shoe box-sized satellite is testing out new, miniaturized technology to measure temperature, water vapor, and cloud ice in the atmosphere. They’ll be tracking major storms, including hurricanes, as well as everyday weather. If this test flight is successful, the new, smaller technology will likely be incorporated into major – large – weather satellite missions in the future that are part of our national infrastructure.

IceCube

The aptly named IceCube will measure – you guessed it – ice in our atmosphere. Unlike the droplets that make up rain, ice is one of the harder things to measure from space. IceCube is a 3-unit CubeSat about the size of a loaf of bread outfitted with a new high-frequency microwave radiometer, an instrument that measures naturally occurring radiation emitted by stuff in the atmosphere – cloud droplets, rain, and the ice particles at the tops of clouds. This will be the first space test of the new microwave radiometer that has to balance its tiny size and low power with being sensitive enough to detect cloud ice. 

CYGNSS: Cyclone, Global Navigation Satellite System

What do GPS signals do when they’re not talking to your phone? A lot of them are just bouncing harmlessly off the planet’s surface – a fact that the CYGNSS mission is taking advantage of to measure wind speed over the ocean. Eight identical small satellites, each about the size of a microwave oven, flying in formation carry custom modified GPS receivers pointed at the oceans. When the water is smooth – not windy – the GPS signals reflect back uniformly, like the moon on a pond reflected as if in a mirror. When the water is choppy – windy – the signals reflect back in in the same direction but distorted, like the moon reflection on a choppy pond being distorted by ripples. Flying eight satellites in formation means the CYGNSS mission can measure wind speed across more of the ocean at once, which will help with understanding tropical storms and hurricanes. 

TROPICS: Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats

An important way to improve forecasts of hurricane and tropical cyclone intensity is to see what’s going on inside and around them while they’re happening. That’s the goal of the TROPICS mission, 12 CubeSats that will fly in formation to track the temperature and humidity of storm environments. The TROPICS CubeSats will get very frequent measurements, similar to X-rays, that cut through the overall cloud-cover so we can see the storm’s underlying structure. The storm structures known as the eyewall – tall clouds, wind and rain around the eye – and rainbands – the rainy parts of the spiral arms – give us clues about whether a storm is primed to intensify into a category 4 or 5 storm, something everyone in their path needs to know.

The First Irregular Moon Discovered on this Day!

On September 19, 1848, astronomers William Cranch Bond, George Phillips Bond and William Lassell discovered the first non-sperical, irregular moon orbiting the planet Saturn, which they named Hyperion (Ὑπερίων) after the Greek god/titan who was the brother of Cronus (the Greek equivalent of Saturn). Looking like a giant potato in the sky, Hyperion is the second largest non-sperical satellite discovered, measuring 360.2×266×205.4 km. Lassell and Bond both observed Hyperion independently of each other only days apart, and only a year after William Herschel had published Results of Astronomical Observations made at the Cape of Good Hope in which he suggested the name scheme for the first seven moons of Saturn, and which Lassell and Bond used when they proposed Hyperion.
