3 Ways You Might Be Marginalizing Disabled Asexual People (And What to Do About It)

Have you noticed how disabled and asexual communities can try to distance themselves from each other? This author's experienced this from all sides, and these examples are so common.

Instead of saying “Asexuality isn’t a disability! Asexual people aren’t disabled,” try “Asexuality isn’t a disability by itself, but there are disabled asexual people and their orientations are just as valid as nondisabled asexual people.”

How Well Do You Know Your Space Photos?

Can you guess the subject of each of these pictures? How many will you get right? Test your friends and family to see who knows their space photos the best.

1. Ice on Earth or a Picture of Mars?

2. Dry Land on Earth or a Close-Up of Jupiter?

3. Mercury or Our Moon?

4. Do You Think This is Mars or Our Home Planet?

5. Waves on Jupiter or Saturn?

6. Is this a picture of Mars or Earth?

7. Can You Tell Which is Europa and Which is the Bottom of a Frying Pan?

8. Close-Up of Our Moon or Dwarf Planet Ceres?

9. A Weird World or Our Own World?

10. The Red Planet or a Red Desert?

Answers

1. Mars. You might be surprised, but this image taken by our Mars Reconnaissance Orbiter is of a light-toned deposit on the Martian surface. Some shapes in the terrain suggest erosion by a fluid moving north to south.

2. Earth. This image taken by our Earth Observing-1 satellite shows Lake Frome in central Australia. In this image, the salt lake appears bone-dry, filled with off-white sediment. This area of Australia receives 149 to 216 millimeters of rainfall a year on average, and the basins pass most of their time as saltpans.

3. Mercury. Our MESSENGER spacecraft captured this image of Mercury during a fly by in October 2008. It shows previously uncharted regions of the planet that have large craters with an internal smoothness similar to Earth’s own moon. It is thought that these craters were to have been flooded by lava flows that are old but not as old as the surrounding more highly cratered surface.

4. Earth. Surprisingly, this image take from the International Space Station shows the western half of the Arabian peninsula in Saudi Arabia. It not only contains large expanses of sand and gravel, but extensive lava fields known as haraat.

5. Saturn. Although this pattern of waves is similar to those seen on Jupiter, this is actually a picture of Saturn. The pattern of an iconic surfer’s wave, has been observed in many places all over the universe, including at the edges of Earth’s magnetic environment.

6. Mars. This image was taken by our Mars Reconnaissance Orbiter and shows dunes of sand-sized materials that have been trapped on the floors of many Martian craters. The dunes are linear, thought to be due to shifting wind directions.

7. Left: Europa. Right: Frying Pan. Europa is one of Jupiter’s moons, and is about the same size as Earth’s moon.

8. Ceres. This image taken by our Dawn spacecraft shows an intriguing mountain on dwarf planet Ceres protruding from a relatively smooth area.

9. Earth. This image of the Bazman volcano is located in a remote region of souther Iran. While the volcano has the classic cone shape of a stratovolcano, it is also heavily dissected by channels that extend downwards from the summit.

10. Earth. This image of the Great Sandy Desert in northwest Australia shows a variety of dune forms across the region. The photo was taken by the Expedition 35 crew from the International Space Station.

Space Food

The holiday season is upon us and much of the festivities revolve around food. While you decide whether to sauté or steam your green beans, let’s take a closer look at what astronauts eat while in space.

Since the start of human spaceflight, we’ve worked to improve the taste, texture and shelf life of food four our crews. Our food scientists are challenged with developing healthy menus that can meet all of the unique requirements for living and working in the extreme environment of space.

Consider the differences of living on Earth and in space. Food scientists must develop foods that will be easier to handle and consume in a microgravity environment. These food products require no refrigeration and provide the nutrition humans need to remain healthy during spaceflight.

Freeze drying food allows food to remain stable at ambient temperatures, while also significantly reducing the weight.

Fun Facts About Space Food:

Astronauts use tortillas in many of their meals

Tortillas provide an edible wrapper to keep food from floating away. Why tortillas and not bread? Tortillas make far less crumbs and can be stored easier. Bread crumbs could potentially float around and get stuck in filters or equipment.

The first food eaten by an American astronaut in space: Applesauce

The first American astronaut to eat in space dined on applesauce squeezed from a no-frills, aluminum toothpaste-like tube. Since then, food technology has cooked up better ways to prepare, package and preserve space fare in a tastier, more appetizing fashion.

All food that is sent to the space station is precooked

Sending precooked food means that it requires no refrigeration and is either ready to eat or can be prepared simply by adding water or by heating. The only exception are the fruit and vegetables stowed in the fresh food locker.

Salt and pepper are used in liquid form on the International Space Station

Seasonings like salt and pepper have to be used in liquid form and dispensed through a bottle on the space station. If they were granulated, the particles would float away before they even reached the food.

Food can taste bland in space

Some people who live in space have said that food is not the same while in microgravity. Some say that it tastes bland, some do not like their favorite foods and some love to eat foods they would never eat on Earth. We believe this phenomenon is caused by something called “stuffy head” This happens when crew member’s heads get stopped up because blood collects in the upper part of the body. For this reason, hot sauce is used A LOT on the space station to make up for the bland flavor.

Astronaut ice cream is not actually eaten on the space station

Even though astronaut ice cream is sold in many science centers and enjoyed by many people on Earth, it’s not actually sent to the space station. That said, whenever there is space in a freezer heading to orbit, the astronauts can get real ice cream onboard! 

Instead of bowls there are bags and cans

Most American food is stored in sealed bags, while most Russian food is kept in cans. 

With all these new facts about space food, you’ll have plenty to talk about over Thanksgiving dinner. 

Here’s a picture of what the crew aboard the space station will enjoy this year: 

Smoked Turkey

Candied Yams

Rehydratable Corn

Potatoes Au Gratin
