NASA Starts Spotting Super Methane Emitters

- Adam Clare

Natural gas, AKA methane, is really bad for the planet, and since it occurs some places “naturally” we need to find these new sources to stop them emitting. A classic example of “natural” methane production is a garbage dump in which the organic compounds mix together and release natural gas, another example is cattle farming (cow farts).

NASA now has a satellite that can detect and therefore monitor these sources of methane. This is really important for two reason: it allows us to better model climate change since we can detect unaccounted for natural gas sources and the other reason is that we can then go and shutdown these previously unrecognized sources.

“Reining in methane emissions is key to limiting global warming. This exciting new development will not only help researchers better pinpoint where methane leaks are coming from, but also provide insight on how they can be addressed — quickly,” NASA Administrator Bill Nelson said in a statement.

Green and other EMIT team members gave some examples of the instrument’s sensitivity during the Tuesday media call. For example, the instrument detected a plume of methane — also known as natural gas — at least 3 miles (4.8 kilometers) long in the sky above an Iranian landfill. This newfound super-emitter is pumping about 18,700 pounds (8,500 kilograms) of methane into the air every hour, the researchers said.

NASA’s All Electric Airplane Looks Neat

- Adam Clare

NASA loves researching and their newest aviation project is no exception. The X-57 plane is an all-electric propeller driven design to test and demonstrate that such a plane can exist. They also went a step further by testing new engines and arrangement of them on the wing to try and create the most effect short range plane possible with current technology. Without a doubt it has been a success! Their plane currently has 500% design efficiency over comparable aircraft on the market, these design solutions can be applied to the next generation of airplanes.

According to the space agency, this final configuration with its bespoke skinny wings will boost efficiency by reducing drag in flight. Propulsion for takeoff and landing is provided by the 12 high-lift electric motors on the leading edge of the wing that allow the X-57 to reach cruising altitude. Then the two wingtip propellers take over as the smaller motors deactivate and their propellor blades fold into the nacelles to reduce drag. For landing, the motors reactivate and centrifugal force opens the blades again.

NASA Designs Plane Modifications to Save Fuel

- Adam Clare

A seemingly simple change to airplane design can make a huge difference in fuel efficiency: add another engine. Yes, as counterintuitive as it sounds, NASA has figured out that by adding an engine to the rear of the plane the airflow of the plane itself can provide more thrust. Airplanes are notoriously bad for the environment and any efficiency in fuel consumption has a significant impact on emissions.

NASA’s idea is pretty straightforward: place a large turbofan engine on the rear of a plane, where it will collect the slow-moving air traveling along the plane’s body. This lets the wing-mounted turbofans be built smaller, which means less drag and a higher fuel efficiency.

That by itself would mean a minor improvement to fuel use, but NASA decided to go a step further. The engineers also added generators to the wing-mounted turbofans, and the electricity generated by these engines is used to power the tail-mounted one. This means that the rear turbofan that provides much of the plane’s thrust doesn’t require any fuel to operate.

These Plants Clean Your Household Air According to NASA

- Adam Clare

forest and river
A few years ago we looked at a TED talk on how to grow fresh air inside. The information was based largely on NASA’s research done in the 1980s called Interior Landscape Plants for Indoor Air Pollution Abatement, which looked into which plants are best for cleaning interior working spaces. They first looked at what is in the air in an average office then set out to find plants that remove chemicals that harm humans.

Here’s the list from NASA and the TED talk:

  • Areca Palm (Chrysalidocarpus lutescens)
  • Weeping Fig
  • Money Plant (Epipremnum aureum)
  • Kimberley Queen Fern
  • Moter-in-law’s Tongue (sansveria trifascata)
  • Lady Palm (Rhapis excelsa)
  • Lillyturf
  • Barberton Daisy
  • Bamboo palm (Chamaedorea seifrizii)
  • Rubber Plant (Ficus robusta)
  • Flamingo Lilly
  • Dwarf Date Palm (Phoenix roebelenii)
  • Spider Plant
  • Chinese Evergreen
  • Ficus Alii (Ficus macleilandii “Alii”)
  • Boston Fern (Nephrolepis exaltata “Bostoniensis”)

Help NASA Find Asteroids

- Adam Clare

Everyday we face an existential threat to our planet from outer space! Asteroids can hit the planet at any moment and ruin our days. To help us prepare for such an event NASA (and other space agencies) are searching for and tracking asteroids. By knowing where they are we can potentially deflect an asteroid to not hit the Earth. Now you can help in this process using your computer at home.

The computer program was created through NASA’s Asteroid Data Hunter challenge, itself a part of the space administration’s larger Asteroid Grand Challenge, and was done in partnership with the Redmond, Washington-based Planetary Resources Inc. The contest, explains a NASA release, was launched at last year’s South By Southwest conference, to develop more sophisticated means of detecting and identifying asteroids by way of land-based telescopes.
