Because most of us spend the majority of our time indoors, NASA conducted a Clean Air Study to determine which common houseplants are the best for filtering harmful toxins like ammonia and formaldehyde from the air.  

**Please note: Several of these plants are known to be toxic to cats, dogs and other pets. If you are a pet owner, please do check the toxicity of plants before introducing them to your home.**

10 “Out of This World" Facts About the James Webb Space Telescope

Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!

Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.

Here are 10 awesome facts about this next generation space telescope:

1. The James Webb Space Telescope is the world’s largest and next premier space observatory. It will extend the discoveries of the Hubble Space telescope and observe the birthplaces of stars, galaxies, planets and life over billions of years.

2. It is named after James Webb, NASA’s second administrator and champion of our science.

3. At 3 stories high and the size of a tennis court, it will be 100 times more powerful than Hubble!

4. It is so big that it has to fold origami-style to fit in the rocket, which is only 5.4 meters wide…And then it will unfurl, segment by segment, once in space.

5. The telescope will observe infrared light with unprecedented sensitivity. It will see the first galaxies born after the Big Bang over 13.5 billion years ago.

6. Webb’s infrared cameras are so sensitive they must be shielded from light from the sun, Earth, and moon. The 5-layer sunshield is like having sunblock of SPF 1 million.

7. Webb will orbit the sun 1 million miles from Earth, where the telescope will operate at temperatures below -390 F (-235 C).

8. Webb’s mirrors are coated with a super thin layer of gold only about 1000 atoms thick to optimize their reflectivity in the infrared.

9. Webb will launch from French Guiana in 2018. It is launched near the equator because the faster spin of Earth there gives the rocket an extra push.

10. Webb is an international mission, with contributions from the European Space Agency and Canadian Space Agency. Once operational, scientists from all over the world will be able to use Webb to explore our solar system, planets outside our solar system, stars and galaxies.

We included Cyberoptix ties in a post waaaaaaaay back in the day, but they certainly warrant a whole post on their own (uh, finally). Actually, more than one post, because these are just a few of my favorite designs from their Space + Aviation section:

Project Mercury (silk)

Skylab space station (microfiber)

Space Shuttle controls (silk) *The product description incorrectly places Endeavor at the Intrepid Museum here in NYC, but they have Enterprise!

NASA’s Hubble Spots Possible Water Plumes Erupting on Jupiter’s Moon Europa

This composite image shows suspected plumes of water vapor erupting at the 7 o’clock position off the limb of Jupiter’s moon Europa. The plumes, photographed by NASA’s Hubble’s Space Telescope Imaging Spectrograph, were seen in silhouette as the moon passed in front of Jupiter. Hubble’s ultraviolet sensitivity allowed for the features – rising over 100 miles (160 kilometers) above Europa’s icy surface – to be discerned. The water is believed to come from a subsurface ocean on Europa. The Hubble data were taken on January 26, 2014. The image of Europa, superimposed on the Hubble data, is assembled from data from the Galileo and Voyager missions.

NASA to Hold Media Call on Evidence of Surprising Activity on Europa

NASA will host a teleconference at 2 p.m. EDT Monday, Sept. 26, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa.

Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa.

Audio of the teleconference will stream live on NASA’s website at http://www.nasa.gov/live

NASA Astronomy Picture of the Day 2016 September 15 

Retrograde Mars and Saturn 

Mars and Saturn have spent much of this year remarkably close in planet Earth’s night sky. In a sequence of exposures spanning mid-December 2015 through the beginning of this week, this composited skyview follows their time together, including both near opposition, just north of bright star Antares near the Milky Way’s central bulge. In the corresponding video, Saturn’s apparent movement is seen to be back and forth along the flattened, compact loop, while Mars traces the wider, reversing S-shaped track from upper right to lower left through the frame. It looks that way, but Mars and Saturn don’t actually reverse direction along their orbits. Instead, their apparent backwards or retrograde motion with respect to the background stars is a reflection of the orbital motion of the Earth itself. Retrograde motion can be seen each time Earth overtakes and laps planets orbiting farther from the Sun, the Earth moving more rapidly through its own relatively close-in orbit.

How Exactly Do We Plan to Bring an Asteroid Sample Back to Earth?

Our OSIRIS-REx spacecraft launches today, and will travel to a near-Earth asteroid, called Bennu. While there, it will collect a sample to bring back to Earth for study. But how exactly do we plan to get this spacecraft there and bring the sample back?

Here’s the plan:

After launch, OSIRIS-REx will orbit the sun for a year, then use Earth’s gravitational field to assist it on its way to Bennu. In August 2018, the spacecraft’s approach to Bennu will begin.

The spacecraft will begin a detailed survey of Bennu two months after slowing to encounter the asteroid. The process will last over a year, and will include mapping of potential sample sites. After the selection of the final site, the spacecraft will briefly touch the surface of Bennu to retrieve a sample.

To collect a sample, the sampling arm will make contact with the surface of Bennu for about five seconds, during which it will release a burst of nitrogen gas. The procedure will cause rocks and surface material to be stirred up and captured in the sampler head. The spacecraft has enough nitrogen to allow three sampling attempts, to collect between 60 and 2000 grams (2-70 ounces).

In March 2021, the window for departure from the asteroid will open, and OSIRIS-REx will begin its return journey to Earth, arriving two and a half years later in September 2023.

The sample return capsule will separate from the spacecraft and enter the Earth’s atmosphere. The capsule containing the sample will be collected at the Utah Test and Training Range.

For two years after the sample return, the science team will catalog the sample and conduct analysis. We will also preserve at least 75% of the sample for further research by scientists worldwide, including future generations of scientists.

The Spacecraft

The OSIRIS-REx spacecraft is outfitted with some amazing instruments that will help complete the mission. Here’s a quick rundown:

The OCAMS Instrument Suite

PolyCam (center), MapCam (left) and SamCam (right) make up the camera suite on the spacecraft. These instruments are responsible for most of the visible light images that will be taken by the spacecraft.

OSIRIS-REx Laser Altimeter (OLA)

This instrument will provide a 3-D map of asteroid Bennu’s shape, which will allow scientists to understand the context of the asteroid’s geography and the sample location.

OSIRIS-REx Thermal Emission Spectrometer (OTES)

The OTES instrument will conduct surveys to map mineral and chemical abundances and will take the asteroid Bennu’s temperature.

OSIRIS-REx Visible and Infrared Spectrometer (OVIRS)

This instrument will measure visible and near infrared light from the asteroid. These observations could be used to identify water and organic materials.

Regolith X-Ray Imaging Spectrometer (REXIS)

REXIS can image X-ray emission from Bennu in order to provide an elemental abundance map of the asteroid’s surface.

Touch-and-Go Sample Arm Mechanism (TAGSAM)

This part of the spacecraft will be responsible for collecting a sample from Bennu’s surface.
