The Moon Just Photobombed NASA’s Solar Dynamics Observatory

The Moon Just Photobombed NASA’s Solar Dynamics Observatory

On May 25, 2017, the moon photobombed one of our sun-watching satellites by passing directly between the satellite and the sun.

image

The Solar Dynamics Observatory, or SDO, orbits Earth and watches the sun nearly 24/7 — except when another body, like the moon, gets in the way. These lunar photobombs are called transits, the generic term for when any celestial body passes in front of another.

Transits are one way we detect distant worlds. When a planet in another star system passes in front of its host star, it blocks some of the star’s light so the star appears slightly dimmer. By monitoring changes in a star’s light over time, scientists can deduce the presence of a planet, and even determine what its atmosphere is like. This method has been used to discover thousands of planets, including the TRAPPIST-1 planets.

image

SDO sees lunar transits about twice a year, and this one lasted about an hour with the moon covering about 89 percent of the sun at the peak of its journey across the sun’s face.

When they’re seen from Earth, we call lunar transits by another name: eclipses.

image

Solar eclipses are just a special kind of transit where the moon blocks all or part of our view of the sun. Since SDO’s view of the sun was only partially blocked, it saw a partial eclipse. Later this year, on Aug. 21, a total eclipse will be observable from the ground: The moon will completely block the sun’s face in some parts of the US, creating a total solar eclipse on a 70-mile-wide stretch of land, called the path of totality, that runs from Oregon to South Carolina.

Throughout the rest of North America — and even in parts of South America, Africa, Europe and Asia — the moon will partially obscure the sun, creating a partial eclipse. SDO will also witness this partial eclipse.

image

Total solar eclipses are incredible, cosmic coincidences: The sun is about 400 times wider than the moon, but it also happens to be 400 times farther away, so the sun and moon appear to be the same size in our sky. This allows the moon to completely block the sun when they line up just right.

image

Within the path of totality, the moon completely obscures the sun’s bright face, revealing the comparatively faint corona — the sun’s pearly-white outer atmosphere.

image

It’s essential to observe eye safety during an eclipse. You must use proper eclipse glasses or an indirect viewing method when any part of the sun’s surface is exposed, whether during the partial phases of an eclipse, or just on a regular day. If you’re in the path of totality, you may look at  the eclipse ONLY during the brief moments of totality.

image

A total solar eclipse is one of nature’s most awe-inspiring sights, so make your plans now for August 21! You’ll also be able to see the eclipse cross the country that day through the eyes of NASA – including views of the partial eclipse from SDO – on NASA TV and at nasa.gov.

Stephen Hawking Says Humans Have 1,000 Years To Leave Earth

Stephen Hawking says humans have 1,000 years to leave Earth

Famed theoretical physicist Stephen Hawking has  grim news for humanity: We have 1,000 years to get off Earth or we’re totally screwed. The 74-year-old  delivered a speech on Tuesday at the Oxford Union in which he said “I don’t think we will survive another 1,000 years without escaping beyond our fragile planet.” He believes it will become impossible for us to keep living here.

Fallstreak Holes Are Natural Phenomena That Often Get Mistaken For UFOs. These ‘hole Punch Clouds’

Fallstreak holes are natural phenomena that often get mistaken for UFOs. These ‘hole punch clouds’ occur when water droplets inside a cloud freeze and fall beneath it, creating a large gap that looks like a perfect hiding place for a flying saucer.

The Orion Nebula And The Running Man 

The Orion Nebula and The Running Man 

 Last night I was able to finally resolve some issues I’ve been having with my new CCD and get a decent image comprised of Luminance and RGB color channels shot through a filter wheel. 

Although I’ve done Orion before this image is substantially higher resolution, incredibly low noise, extremely well color balanced, and far more detailed than any previous attempt. This is a work in progress until I can get another hour or two worth of exposure to reveal Orion in all it’s beauty.

Solar System: Things to Know This Week

Our solar system is huge, let us break it down for you. Here are a few things to know this week:

1. Juno Eyes on Jupiter

Solar System: Things To Know This Week

After a journey of more than five years, the Juno spacecraft is ready for its detailed look at Jupiter—arrival date: July 4. Using Eyes on the Solar System and data from the Juno flight team, you can take a virtual ride onboard the spacecraft in the “Eyes on Juno” simulation.

2. Taking a Spacecraft for a Spin

Solar System: Things To Know This Week

Preparations for the launch of the OSIRIS-REx asteroid mission are spinning up, literally. Here, the spacecraft can be seen rotating on a spin table during a weight and center of gravity verification test at our Kennedy Space Center. Liftoff is scheduled for Sept. 8. This spacecraft will travel to a near-Earth asteroid called Bennu and bring a small sample back to Earth for study.

3. Long-Range (Or at Least Long-Distance) Weather Report

Solar System: Things To Know This Week

Our Mars Reconnaissance Orbiter acquires a global view of the red planet and its weather every day. Last week, dust storms continued along the south polar ice cap edge. Northern portions of Sirenum, Solis, and Noachis also experienced some local dust-lifting activity. A large dust storm propagated eastward over the plains of Arcadia at the beginning of the week, but subsided just a few days later over Acidalia.

4. Hello from the Dark Side

Solar System: Things To Know This Week

The New Horizons spacecraft took this stunning image of Pluto only a few minutes after closest approach in July 2015, with the sun on the other side of Pluto. Sunlight filters through Pluto’s complex atmospheric haze layers. Looking back at Pluto with images like this gives New Horizons scientists information about Pluto’s hazes and surface properties that they can’t get from images taken on approach.

5. A Titanic Encounter

Solar System: Things To Know This Week

On June 7, our Cassini orbiter will fly very close by Saturn’s giant, haze-shrouded moon Titan. Among the targets of its observations will be the edge of the vortex that swirls in Titan’s thick atmosphere near its south pole.

10 Technologies That Are Changing the Game

Earlier this year, we hosted a Game Changing Technology Industry Day for the aerospace industry, and in October our engineers and technologists visited Capitol Hill showcasing some of these exciting innovations. Check out these technology developments that could soon be making waves on Earth and in space.

1. Wearable technology

image

With smartwatches, glasses, and headsets already captivating users around the world, it’s no surprise that the next evolution of wearable technology could be used by first responders at the scene of an accident or by soldiers on a battlefield. The Integrated Display and Environmental Awareness System (IDEAS) is an interactive optical computer that works for smart glasses. 

image

It has a transparent display, so users have an unobstructed view even during video conferences or while visualizing environmental data. 

image

And while the IDEAS prototype is an innovative solution to the challenges of in-space missions, it won’t just benefit astronauts – this technology can be applied to countless fields here on Earth.

2. Every breath they take: life support technologies

Before astronauts can venture to Mars and beyond, we need to significantly upgrade our life support systems. The Next Generation Life Support project is developing technologies to allow astronauts to safely carry out longer duration missions beyond low-Earth orbit. 

image

The Variable Oxygen Regulator will improve the control of space suit pressure, with features for preventing decompression sickness. The Rapid Cycle Amine technology will remove carbon dioxide and humidity and greatly improve upon today’s current complex system.

image

3. 3-D printing (for more than just pizza)

New Advanced Manufacturing Technologies (AMT), such as 3-D printing, can help us build rocket parts more quickly and aid in building habitats on other planets. 

image

These manufacturing initiatives will result in innovative, cost-efficient solutions to many of our planetary missions. Back in 2014, the International Space Station’s 3-D printer manufactured the first 3-D printed object in space, paving the way to future long-term space expeditions. 

image

The object, a printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with us to design, build and test the 3-D printer.

image

4. Spacecraft landing gear

Large spacecraft entering the atmosphere of Mars will be traveling over five times the speed of sound, exposing the craft to extreme heat and drag forces. The Hypersonic Inflatable Aerodynamic Decelerator (HIAD) is designed to protect spacecraft from this environment with an inflatable structure that helps slow a craft for landing. 

image

To get astronauts and other heavy loads to the surface safely, these components must be very strong. The inflatable consists of a material 15 times stronger than steel, while the thermal protection system can withstand temperatures over 1600°C.

5. From heat shield technology to firefighter shelters

image

For the Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) project, we partnered with the U.S. Forest Service to develop safer, more effective emergency fire shelters for wild land firefighters. 

image

Using existing technology for flexible spacecraft heat shields like HIAD, we are building and testing new fire shelters composed of stacks of durable, insulated materials that could help protect the lives of firefighters.

image

6. Robots and rovers

Real life is looking a bit more like science fiction as Human Robotics Systems are becoming highly complex. They are amplifying human productivity and reducing mission risk by improving the effectiveness of human-robot teams. 

image

Our humanoid assistant Robonaut is currently aboard the International Space Station helping astronauts perform tasks.

image

A fleet of robotic spacecraft and rovers already on and around Mars is dramatically increasing our knowledge and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back data from the surface. 

image

This data will help us plan how to protect the astronauts who will explore Mars. 

image

Future missions like the Mars 2020 rover, seeking signs of past life, will demonstrate new technologies that could help astronauts survive on the Red Planet.

image

7. Robotic repairs

Currently, a satellite that is even partially damaged cannot be fixed in orbit. Instead, it must be disposed of, which is a lot of potential science lost.

image

Satellite Servicing technologies would make it possible to repair, upgrade, and even assemble spacecraft in orbit using robotics.

image

This can extend the lifespan of a mission, and also enable deeper space exploration. 

image

Restore-L, set to launch in 2020, is a mission that will demonstrate the ability to grab and refuel a satellite.

8. Low-cost spacecraft avionics controllers

Small satellites, or smallsats, are quickly becoming useful tools for both scientists and industry. However, the high cost of spacecraft avionics—the systems that guide and control the craft—often limits how and when smallsats can be sent into orbit by tagging along as payloads on larger launches. 

image

Using Affordable Vehicle Avionics (AVA) technology, we could launch many more small satellites using an inexpensive avionics controller. This device is smaller than a stack of six CD cases and weighs less than two pounds!

9. Making glass from metal

After a JPL research team of modern-day alchemists set about mixing their own alloys, they discovered that a glass made of metal had the wear resistance of a ceramic, was twice as strong as titanium, and could withstand the extreme cold of planetary surfaces, with temperatures below -150 degrees Fahrenheit.

image

Bulk Metallic Glass (BMG) gears would enable mechanisms to function without wasting energy on heaters. Most machines need to maintain a warmer temperature to run smoothly, which expends precious fuel and decreases the mission’s science return. 

image

By developing gearboxes made of BMG alloys, we can extend the life of a spacecraft and learn more about the far reaches of our solar system than ever before. Plus, given their extremely high melting points, metallic glasses can be cheaply manufactured into parts by injection molding, just like plastics.

10. Lighter, cheaper, safer spacecraft fuel tanks

Cryogenic propellant tanks are essential for holding fuel for launch vehicles like our Space Launch System—the world’s most powerful rocket. But the current method for building these tanks is costly and time-consuming, involving almost a mile of welded parts.

image

Advanced Near Net Shape Technology, part of our Advanced Manufacturing Technologies, is an innovative manufacturing process for constructing cryotanks, using cylinders that only have welds in one area. 

image

This makes the tank lighter, cheaper, and safer for astronauts, as there are fewer potentially defective welds.

Sleepless Wolf Report

Hi guys!

Do you know the feeling when your body tells you that you need to sleep, but your brain are restless? 

My head is aching from all the nights I haven’t being sleeping well. I’m feeling anxious about my mother who is in a hospital again, luckily it’s not anything too bad. I’m also restless because I’m moving to a new apartment soon. I need to find a job to have my bills payed and have some money to spend after. I know I’m not alone with these kind of problems, but I have none to speak with, so I write them down to ease my brain. I could use them to so many more fascinating things than anxiety and mental breakdowns in the middle of the night.
