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. The New New Horizons

Seven months after the  Pluto flyby, information and discoveries continue to flow from the New Horizons mission, as the spacecraft transmits more and more data to scientists on Earth.

2. A Longlasting Dawn

The Dawn orbiter is in good health as it carries out the ongoing reconnaissance of the dwarf planet Ceres, which is revealing some spectacular and mysterious landscapes.

3. Storm Watch: Saturn

This week the Cassini spacecraft will be watching for storms in Saturn’s turbulent atmosphere. On March 6, it will spend about 14 hours acquiring a movie of the narrow, braided F ring. Check out some past photos of Saturnian storms HERE.

4. The Next Flight to Mars Departs Soon

The ExoMars 2016 mission, a joint endeavor between the European Space Agency and the Russian space agency Roscosmos, is set to lift off in March. The 2016 mission consists of the Trace Gas Orbiter and the Schiaparelli Entry, Descent and Landing Demonstrator Module. We’re supplying some of the technology that will fly aboard the orbiter. In 2018, the ExoMars rover is slated to follow.

5. Early Encounter with a Comet

As we continue to marvel at the latest images from Rosetta, this week is a good time to remember the 30th anniversary of the Vega 1 Comet Halley flyby. This Russian spacecraft dropped off a balloon probe at Venus before continuing on to the comet, which is photographed and examined at close range by flying through its coma.

All Eyes on the Sky for the August 21 Total Solar Eclipse

Just two months from now, the moon will completely block the sun’s face, treating part of the US to a total solar eclipse.

Everyone in North America will have the chance to see an eclipse of some kind if skies are clear. Anyone within a 70-mile-wide swath of land — called the path of totality — that stretches from Oregon to South Carolina will have the chance to see a total eclipse.

Throughout the rest of the continent, including all 50 United States — and even in parts of South America, Africa, Europe, and Asia — the moon will partially obscure the sun, creating a partial eclipse.

An eclipse is one of nature’s most awesome sights, but safety comes first! When any part of the sun’s surface is exposed, use proper eclipse glasses (not sunglasses) or an indirect viewing method, like a pinhole projector. In the path of totality, it’s safe to look directly at the eclipse ONLY during the brief moments of totality.

During a solar eclipse, the moon passes between the sun and Earth, casting a shadow down on Earth’s surface. We’ve been studying the moon with NASA’s Lunar Reconnaissance Orbiter, and its precise mapping helped NASA build the most accurate eclipse map to date.

During a total solar eclipse, the moon blocks out the sun’s bright face, revealing the otherwise hidden solar atmosphere, called the corona. The corona is one of the sun’s most interesting regions — key to understanding the root of space weather events that shape Earth’s space environment, and mysteries such as why the sun’s atmosphere is so much hotter than its surface far below.

This is the first time in nearly 100 years that a solar eclipse has crossed the United States from coast to coast. We’re taking advantage of this long eclipse path by collecting data that’s not usually accessible — including studying the solar corona, testing new corona-observing instruments, and tracking how our planet’s atmosphere, plants, and animals respond to the sudden loss of light and heat from the sun.

We’ll be studying the eclipse from the ground, from airplanes, with research balloons, and of course, from space.

Three of our sun-watchers — the Solar Dynamics Observatory, IRIS, and Hinode, a joint mission led by JAXA — will see a partial eclipse from space. Several of our Earth-observing satellites will use the eclipse to study Earth under uncommon conditions. For example, both Terra and DSCOVR, a joint mission led by NOAA, will capture images of the moon’s shadow from space. Our Lunar Reconnaissance Orbiter will also turn its instruments to face Earth and attempt to track the moon’s shadow as it moves across the planet.

There’s just two months to go until August 21, so make your plans now for the big day! No matter where you are, you can follow the eclipse as it crosses the country with live footage from NASA TV.

A magnetic power struggle of galactic proportions - new research highlights the role of the Sun’s magnetic landscape in the development of solar eruptions that can trigger space weather events around Earth.

Using data from our Solar Dynamics Observatory, scientists examined an October 2014 Jupiter-sized sunspot group, an area of complex magnetic fields, often the site of solar activity. This was the biggest group in the past two solar cycles and a highly active region. Though conditions seemed ripe for an eruption, the region never produced a major coronal mass ejection (CME) - a massive, bubble-shaped eruption of solar material and magnetic field - on its journey across the Sun. It did, however, emit a powerful X-class flare, the most intense class of flares. What determines, the scientists wondered, whether a flare is associated with a CME?

The scientists found that a magnetic cage physically prevented a CME from erupting that day. Just hours before the flare, the sunspot’s natural rotation contorted the magnetic rope and it grew increasingly twisted and unstable, like a tightly coiled rubber band.

6 Ways NASA Space Communications Connect Astronauts to Earth

1. When Astronauts Phone Home, the Space Network Answers 

Operated by our Goddard Space Flight Center in Greenbelt, Maryland, this communications system enables all types of Earth-to-astronaut communication.  The Space Network is a complex system of ground station terminals and satellites. The satellites, called ‘Tracking and Data Relay Satellites’ or TDRS, provide continuous communications for human spaceflight 24/7/365. The information this network relays includes astronaut communication with Mission Control in Houston, posting live video of spacewalks and live interviews with schools, even posting Tweets on Twitter and doing Facebook posts. The Space Network can even broadcast live 4K, ultra-HD video right from the station. You can now watch an astronaut eat a space taco in high definition. WHAT A TIME TO BE ALIVE!

2. The Space Network Also Communicates Science Data 

Astronauts on the Space Station perform experiments on the station that will enable our Journey to Mars and other future human space missions. For example, astronaut Peggy Whitson works on a bone cell study that could lead to better preventative care or therapeutic treatments for people suffering bone loss as a result of bone diseases like osteopenia and osteoporosis, or for patients on prolonged bed rest. All that fantastic data is sent back to Earth via our Space Network for scientists around the world to analyze and build on.

3. The Space Network Transmits Spacecraft Health Data

The Space Network not only lets us communicate with the astronauts, it also tracks the ‘health’ of the spacecraft, be it the International Space Station where the astronauts are living, a cargo vehicle servicing the space station, or even, in the near future, crewed vehicles to other worlds. We deliver data on a spacecraft’s state of health, from power generation levels and avionics status to carbon dioxide and oxygen levels, and more to Mission Control 24/7/365.

4. The Space Network Helps Monitor Spacecraft Location

The International Space Station Is pretty big, but space is bigger. The Space Network enables flight controllers on the ground to provide a GPS-type service for the Space Station, letting them track the exact location of the space station at all times as it orbits the Earth. It also allows us Earth-bound folk to get real-time text updates when the Space Station is flying overhead. If you want to track the station, sign up here: https://spotthestation.nasa.gov

5. The Space Network Supports Launch Vehicles

Goddard’s Space Network also controls all the communications for all the missions that go to the space station. That includes command and telemetry services during launches, free flight, berthing and un-berthing to the station, as well as re-entry and landing back to Earth. 

6. The Space Network Is Also Looking Toward the Future

It’s also helping to test vehicles that will carry astronauts to other worlds. Currently, they are working with teams for our Space Launch System and commercial crew vehicles. The first flights for these vehicles will occur in 2018 and 2019, setting us on the road to Journey to Mars! This image shows the Orion capsule that will aid in our continuous march into space. 

What’s Next for the Space Network? 

We’re continuing to grow! Watch out for the launch of a new TDRS spacecraft in August 2017! TDRS-M is coming. Check out more info here and join our countdown to TDRS launch: https://tdrs.gsfc.nasa.gov. 

Solar System: Things to Know This Week

Discoveries in planetary science are often both weird and wonderful, and these newest announcements are no exception. This week we present a few of the most interesting recent scientific findings from our missions and NASA-funded planetary science. Take a look:

1. Seeing Spots

Scientists from our Dawn mission unveiled new images from the spacecraft’s lowest orbit at the dwarf planet Ceres, including highly anticipated views of the famous “bright spots” of Occator Crater. Take a look HERE.

2. Pluto’s Secrets Brought to Light

A year ago, Pluto was just a bright speck in the cameras of our approaching New Horizons spacecraft, not much different than its appearances in telescopes since Clyde Tombaugh discovered the dwarf planet in 1930. Now, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby. Find out more HERE.

3. Rising Above the Rest

In a nod to extraterrestrial mountaineers of the future, scientists working on our Cassini mission have identified the highest point on Saturn’s largest moon, Titan. The tallest peak is 10,948 feet (3,337 meters) high and is found within a trio of mountainous ridges called the Mithrim Montes, named for the mountains in Tolkien’s Middle-Earth.

4. Does the “Man in the Moon” Have a New Face?

New NASA-funded research provides evidence that the spin axis of Earth’s moon shifted by about five degrees roughly three billion years ago. The evidence of this motion is recorded in the distribution of ancient lunar ice, evidence of delivery of water to the early solar system.

5. X-Ray Vision

Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s “northern lights,” according to a new study using data from our Chandra X-ray Observatory.

Space Station Research: Cardiovascular Health

Each month, we highlight a different research topic on the International Space Station. In February, our focus is cardiovascular health, which coincides with the American Hearth Month.

Like bones and muscle, the cardiovascular system deconditions (gets weaker) in microgravity. Long-duration spaceflight may increase the risk of damage and inflammation in the cardiovascular system primarily from radiation, but also from psychological stress, reduced physical activity, diminished nutritional standards and, in the case of extravehicular activity, increased oxygen exposure.

Even brief periods of exposure to reduced-gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities and diminished aerobic capacity.

The weightless environment of space also causes fluid shifts to occur in the body. This normal shift of fluids to the upper body in space causes increased inter-cranial pressure which could be reducing visual capacity in astronauts. We are currently testing how this can be counteracted by returning fluids to the lower body using a “lower body negative pressure” suit, also known as Chibis.

Spaceflight also accelerates the aging process, and it is important to understand this process to develop specific countermeasures. Developing countermeasures to keep astronauts’ hearts healthy in space is applicable to heart health on Earth, too!

On the space station, one of the tools we have to study heart health is the ultrasound device, which uses harmless sound waves to take detailed images of the inside of the body. These images are then viewed by researchers and doctors inside Mission Control. So with minimal training on ultrasound, remote guidance techniques allow astronauts to take images of their own heart while in space. These remote medicine techniques can also be beneficial on Earth.

Can You Guess Which Football Signals Robonaut Is Doing?

Meet Robonaut, our humanoid robot (which means it’s built to look like a person). This makes it easier for Robonaut to do the same jobs as a person. 

Robonaut could help with anything from working on the International Space Station to exploring other worlds…and now he might even take up a job as a referee!

We had Robonaut act out a few football signals. Can you guess what they are?!

Signal #1

Signal #2

Signal #3

Signal #4

Signal #5

Signal #6

Signal #7

Signal #8

Signal #9

Get the answers:

But it’s not all fun and games for Robonaut...from performing movements like a referee to helping astronauts on the space station, it’s important to have a robot that can perform the same tasks as humans. Why?  

Robonaut could someday be tested outside the space station. This testing would determine how well Robonaut could work with, or instead of, spacewalking astronauts. Designers even have ideas for sending a robot like Robonaut to another world someday. If testing goes well, who knows where Robonaut - or a better robot based on Robonaut - could end up?
