Amy’s Everyday Astronomy: The Best in Space for 2018

As 2018 comes to a close, I wanted to take a look back at some of the best space stories of the year and tell you about some really cool upcoming events for 2019.

Earlier this year, we watched as SpaceX’s Falcon Heavy launched in February sending Elon Musk’s Tesla (piloted by Starman) out into the solar system and we sat in awe as the two booster rockets made it safely back to the launch pad, landing side by side.

Back in August, NASA launched the Parker Solar Probe which is currently collecting data from its highly elliptical orbit that brings it within 4 million miles of the sun. Around this same time, OsirisRex reached Bennu where it is collecting samples of the asteroid for return to Earth for detailed study. And just this month, OsirisRex confirmed the existence of water beneath the surface of Bennu.

But that’s not the only place water was found: ice was also detected on the north and south poles of the moon, as well as in the atmosphere of exoplanet HR 8799C.

Sadly, there were also some losses: both the Kepler Telescope, which made many awesome exoplanet discoveries, and the Dawn spacecraft that orbited dwarf planets Vesta and Ceres ran out of fuel, putting an end to their very successful missions. And in October, the Soyuz spacecraft was forced to abort its mission during launch due to booster separation failure.

But despite these setbacks, NASA was still able to keep us on the edge of our seats with the successful landing of InSight on the surface of Mars. This would mark its first landing on the Red Planet’s surface in over six years. And as a shining example of their many decades of space exploration, NASA also announced that the Voyager 2 probe has entered interstellar space.

But perhaps one of the most surprising of all is the announcement by NASA Chief, Jim Bridenstine, that they will be working with commercial companies for the purposes of sending humans back to the moon…to stay.

For 2019, you can expect the year to start off with a bang as New Horizons, the spacecraft that brought us those beautifully detailed pictures of Pluto, zips past Ultima Thule, a tiny little rocky body in the Kuiper Belt that’s about the size of New York City. You can watch flyby live on the mission website or on YouTube.

And on January 20th, go outside and look up, because starting at 7:36pm MST sky watchers in both North and South America will be in for a treat as the Wolf Moon turns blood red. You can expect to be outside for a while because totality doesn’t happen until about 10:12pm MST.

So, bundle up and bring your lawn chairs, because you never know what you’ll see if you just keep your eyes to the skies.

Amy’s Everyday Astronomy: NASA Brings First Mars Landing in Six Years to Viewers Everywhere 

As one of three planets in the habitable zone of our sun, Mars is ripe for study. While Venus is similar in size to Earth, its atmospheric composition is such that anything we try to send down to the surface gets crushed within minutes.

This makes Mars the best place, outside of Earth, itself, to send probes and landers. And over the decades, we’ve sent many spacecrafts to Mars to study the surface history of the planet by examining canyons, rocks, soil, and weather patterns.

But soon, scientists at NASA are going to go “in depth” in their research of Mars. Launched on March 5th, the first NASA spacecraft to venture to the Red Planet since the Curiosity Rover arrived in 2012 will touch down on November 26th.

The new InSight lander will reach the Martian surface where it will begin investigating the ‘inner space’ of the Red Planet.

Short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, the lander is designed to study the crust, mantle, and core of the planet.

By studying the interior structure of Mars, scientists will be able to get information about the early formation of rocky planets, like those in our inner solar system.

Insight will be measuring tectonic activity, as well as meteorite impacts.

You’ll remember that in recent news, there was controversy over an icy cloud formation over the summit of Arsia Mons that some believed was actually a volcanic eruption in progress. InSight will answer whether any volcanic activity has occurred in recent decades.

The lander, which uses cutting edge instruments, will do this by measuring the planet’s seismology, heat flow, and precision tracking.

The InSight lander is being followed to Mars by two smaller spacecraft called CubeSats, according to NASA. Mars Cube One (MarCo) will be the first deep-space mission for the CubeSats.

As MarCo makes its scheduled flyby of Mars, it will attempt to relay data from the InSight lander as it enters the planet’s atmosphere and lands.

If you’d like to watch the landing live, you can check out the broadcast schedule online.  You can also follow the landing on social media at Twitter and Facebook.

Amy’s Everyday Astronomy: Swedish Research Team Develops New Solar Energy Storage Method

El Paso is known as the Sun City for a good reason. From blistering summers, to mild winters, the desert southwest knows the sun well.

On average, we experience more sunny days than any other kind of weather. And given the amount of energy the sun puts out every hour—enough to power the entire planet Earth for one year—you’d think converting to solar power would be the best option. But with the cost of solar paneling and converting buildings to use these options, it can be very a little expensive to make the change.

Surprisingly, the biggest drawback to solar power conversion may be the batteries. They store only a limited amount of the total energy received by the sun. This means power usage needs to be closely monitored. Gauges and meters must be observed in order to insure you have enough energy to use at night and during cloudy days. We won’t even talk about the recurring cost of replacing the batteries when needed.

But a change could soon be on the horizon.

A research team in Sweden has made a potential breakthrough in the ability to store solar energy. As an alternative to batteries, the team has developed a specialized fluid called Solar Thermal Fuel. Composed of carbon, hydrogen, and nitrogen, the fluid can hold energy from the sun for long periods of time and expel it on demand in the form of heat. When the molecules are hit by sunlight, the bonds between atoms are rearranged. This chemical conversion traps energy within the molecules. The energy stays in the storage container even when the molecules cool down to room temperature.

When energy is needed, the molecules are passed through a catalyst. This process rearranges the chemical bonds back to what they were which releases a lot of heat. The hope is that this can be used in residential heating systems, water heaters, dishwashers, clothes dryers, and much more.

In a recent interview with NBC News, MIT engineer, Jeffrey Grossman explained, “A solar thermal fuel is like a rechargeable battery, but instead of electricity, you put sunlight in and get heat out, triggered on demand.”

The emissions-free energy system can now store energy for up to 18 years, according to nanomaterials scientist Kasper Moth-Poulsen from Chalmers University. In fact, the researchers claim their fluid are currently capable of holding 250 watt-hours of energy per kilogram. According to the NBC interview, that’s double the capacity of Tesla’s Powerwall batteries.

This has the potential to save money and cut down on pollution when it comes to the various heating needs of a home or commercial building. All that’s left is to figure out how to turn this energy into usable electricity for powering all our electronic devices.

Amy’s Everyday Astronomy: Is Mars Still Volcanically Active?

Since its discovery, Mars has always been a place of wonder for us Earthlings. From long ago beliefs that the deep canyons seen in telescopes were forged by water, to fear of invasion from little green men.

Mars fires the imagination of sci-fi literature and films, as well as the real science of current and future mission planning. And there’s no limit to the conspiracy theories that circulate about this planet named for the Roman God of War. Whatever the reason, Mars is almost always in the news.

The Red Planet falls within the habitable zone of our sun. And, indeed, many scientists believe Mars once housed oceans and rivers, and maybe even life of some type. But one of the really cool features of Mars is that it is also home to the largest volcano in the solar system, Olympus Mons.

Similar in size to the state of Arizona, Olympus Mons forms a strange triangular shape with three other volcanos in the region: Ascraeus Mons, Pavonis Mons, and Arsia Mons. Known as the Tharsis Volcanos, most of these haven’t been active for 2 million years.

Most recently, however, speculations and theories have run amok that Mars may still be volcanically active. With the recent closure of the solar observatory in New Mexico and even more recent YouTube outage, conspiracists believe that pictures taken by the Mars Reconnaissance Orbiter earlier this month show a plume of smoke being emitted by Arsia Mons.

That would bode well for any potential life that might inhabit the planet. If the volcanos were still active, that would mean subsurface water has a decent chance of being warm enough to support life.

Unfortunately, there’s more ice than fire about that plume captured in the photos. According to NASA, “These are ice-rich clouds over the summit of Arsia Mons.”

In reality, Arsia Mons hasn’t erupted in over 10 million years. Dr. Tanya Harrison, a member of NASA’s Opportunity rover team who specializes in Martian geology and weather patterns took to Twitter to dispel the myths.

“It’s not a plume of smoke, but rather water ice clouds condensing out over the summit of the Arsia Mons volcano. We see them quite often over this particular volcano. We see these clouds hang out over the summit of Arsia for weeks at a time during this time of year, every year,” Harrison writes.

In essence, that’s no Mons [eruption], that a stationary [ice cloud].
