A teenager designed a pocket-sized satellite that will fly on a NASA mission

An 18-year-old created the world’s lightest functioning satellite, and it’s going to be launched on a real NASA mission next month.

Rifath Sharook, who is from Tamil Nadu, India, made the pocket-sized satellite for a competition called Cubes in Space, which is an international design challenge that asks students aged 11 to 18 to fit their space-worthy invention inside a 13-foot cube.

The pocket-sized 3-D printed satellite is much smaller than that. It weighs just 0.14 pounds and will measure the rotation, acceleration and magnetosphere of Earth, Sharook told Business Standard. Read more (5/17/17)

Binary star systems have come up a lot in the past 18 podcasts, and here is a perfect example of them!

As promised, here is a comic about the brightest star in the northern Hemisphere: Sirius! Sirius B will be shown in future comics as 2018 is year of the dog and since Sirius is the dog star, it is year of the Sirius!

Enjoy!

A new LEGO set honors the women of NASA—and it looks pretty awesome

"The set clearly touched and inspired many."

Oh my gosh this is incredibly exciting! Imagine combining them with a Star Wars LEGO set...

When the sun sets on Stonehenge on the shortest day of the year, it’s rays align with several important stones.  Twice a year, the streets of Manhattan also line up with the setting sun, a phenomenon dubbed “Manhattanhenge”. Really, most cities with grid systems will see a similar effect (though it’s most dramatic in cities with tall buildings and a view of the true horizon).  You can use a great tool called The Photographer’s Ephemeris to find out the “henge” dates for your city grid - or even individual streets.

Yesterday, (Friday, January 24th) the sun lined up with New York Avenue, a street in DC that runs diagonally up to the White House. (The orange line indicates alignment with the setting sun).

I went out with our multimedia intern Meg Vogel, and captured some images of the sun setting in line with a rather Stonehenge-y sculpture that sits in the middle of that street.

Here are dates for sunset “henge” events in some cities this year:

Manhattan May 25th, July 17th

Philadelphia April 5th, September 6th

Washington DC March 18th, September 24th

Chicago March 16th, September 26th

Phoenix March 20th, September 22nd

Portland, OR March 18th, September 24th

Is your city/town a grid? When’s your henge?

Ongoing Space Science Seeks to Keep Astronauts Healthy

ISS - Expedition 50 Mission patch. March 10, 2017 NASA is preparing for longer human journeys deeper into space and is exploring how to keep astronauts healthy and productive. The Expedition 50 crew members today studied space nutrition, measured their bodies and checked their eyes to learn how to adapt to living in space. The space residents also unloaded a cargo ship, worked on the Tranquility module and practiced an emergency simulation. The ongoing Energy experiment that ESA astronaut Thomas Pesquet collected urine samples for today seeks to define the energy requirements necessary to keep an astronaut successful during a space mission. Pesquet also joined NASA astronaut Peggy Whitson for body measurements to learn how microgravity affects body shape and impacts crew suit sizing. Commander Shane Kimbrough checked his eyes today with Whitson’s help and support from experts on the ground.

Kimbrough worked throughout the day before his eye checks and configured the Tranquility module for upcoming electronics and communications work. Cosmonaut Oleg Novitskiy continued unloading gear from the newly-arrived Progress 66 cargo ship. At the end of the day, Novitskiy joined Whitson and Pesquet for an emergency simulation with inputs from control centers in Houston and Moscow.

27 of Hubble's Best Photos for Its 27th Birthday

Hubble turns 27 today. Here's a look back at some of its most noteworthy accomplishments.

You may recognize the seventh picture in the slideshow--it’s my profile picture here. Happy birthday Hubble, you’re older than I am!

Physicists Have Figured Out Where The Sun's Plasma Jets Come From

Things are heating up.

After over a century of observations and several theories, scientists may have finally nailed the origin of the high-speed plasma blasting through the Sun’s atmosphere several times a day. Using a state-of-the-art computer simulation, researchers have developed a detailed model of these plasma jets, called spicules.

The new findings answer some of the bigger questions in solar physics, including how these plasma jets form and why the Sun’s outer atmosphere is far hotter than the surface.

“This is the first model that has been able to reproduce all the features observed in spicules,” Juan Martinez-Sykora, lead author and astrophysicist at the Bay Area Environmental Research Institute in California, told ScienceAlert.

I wish I’d found this before Episode 19, dang it! Such good gifs of astronauts, though.

Coffee in Space: Keeping Crew Members Grounded in Flight

Happy National Coffee Day, coffee lovers! 

On Earth, a double shot mocha latte with soymilk, low-fat whip and a caramel drizzle is just about as complicated as a cup of coffee gets. Aboard the International Space Station, however, even just a simple cup of black coffee presents obstacles for crew members.

Understanding how fluids behave in microgravity is crucial to bringing the joys of the coffee bean to the orbiting laboratory. Astronaut Don Pettit crafted a DIY space cup using a folded piece of overhead transparency film. Surface tension keeps the scalding liquid inside the cup, and the shape wicks the liquid up the sides of the device into the drinker’s mouth.

The Capillary Beverage investigation explored the process of drinking from specially designed containers that use fluid dynamics to mimic the effect of gravity. While fun, this study could provide information useful to engineers who design fuel tanks for commercial satellites!

The capillary beverage cup allows astronauts to drink much like they would on Earth. Rather than drinking from a shiny bag and straw, the cup allows the crew member to enjoy the aroma of the beverage they’re consuming.

On Earth, liquid is held in the cup by gravity. In microgravity, surface tension keeps the liquid stable in the container.

The ISSpresso machine brought the comforts of freshly-brewed coffees and teas to the space station. European astronaut Samantha Cristoforetti enjoyed the first cup of espresso brewed using the ISSpresso machine during Expedition 43.

Now, during Expedition 53, European astronaut Paolo Nespoli enjoys the same comforts. 

Astronaut Kjell Lindgren celebrated National Coffee Day during Expedition 45 by brewing the first cup of hand brewed coffee in space.
