As Seen on @CBSThisMorning, which is posting some of our images each morning this week - This image from NASA's Solar Dynamics Observatory shows a solar flare -- the bright light on the left side of the sun -- on July 8, 2014. An eruption of solar material can also be seen arcing up and away. After it left the sun, this arc of material became a coronal mass ejection, a giant cloud of solar material, headed toward Mars. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. Flares move at the speed of light, and can reach Earth in eight minutes. Coronal mass ejections, on the other hand, send actual solar material and particles out into space moving much more slowly: typically around 500-1000 miles per second.

As Seen on @CBSThisMorning, which is posting some of our images each morning this week: Making Tracks on Mars. Our Curiosity rover is driving toward Mount Sharp on Mars. Using the front and rear hazard cameras ("hazcams") we see the 3-kilometer-tall Mount Sharp looming ahead, and fresh rover tracks left behind. Since landing, Curiosity has driven 5 miles (8 kilometers) stopping to do science along the way. One of Curiosity's first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms. The answer, a historic "yes," came from two mudstone slabs that the rover sampled with its drill. Analysis of these samples revealed the site was once a lakebed with mild water, the essential elemental ingredients for life, and a type of chemical energy source used by some microbes on Earth. If Mars had living organisms, this would have been a good home for them. Rovers are gathering valuable scientific information and helping pave the #PathToMars as part of our #NextGiantLeap -- sending astronauts to the Red Planet.

Five Space Legends: Former shuttle and Apollo astronauts today toured the refurbished Operations and Checkout Building, newly named for Apollo 11 astronaut Neil Armstrong, the first person to set foot on the moon. Viewing the Orion crew module stacked on top of the service module from left, are former shuttle astronaut and Kennedy Center Director Bob Cabana, Apollo 11 astronaut Michael Collins, Apollo astronaut Jim Lovell, Apollo 11 astronaut Buzz Aldrin, and former shuttle astronaut and NASA Administrator Charlie Bolden. The building's high bay is being used to support the agency's new Orion spacecraft, which will lift off atop the Space Launch System. Orion is designed to take humans farther than they've ever gone before, serving as the exploration vehicle that will carry astronauts to deep space and sustain the crew during travel to destinations such as an asteroid or Mars.

A space freighter is set to depart the International Space Station Monday, clearing the way for the next express delivery of cargo on Wednesday. The Russian ISS Progress 55 cargo craft spent more than three months at the orbiting complex and delivered nearly three tons of food, fuel and supplies when it arrived at the orbiting complex on April 9. In this image, the Soyuz TMA-13M spacecraft (foreground) and the ISS Progress 55 cargo ship are docked to station. Image Credit: NASA #nasa #space #spacestation #iss #exp40 #progress #science; -
Our Orion Crew Module has been stacked on the service module inside the Operations and Checkout Building at Kennedy Space Center -- renamed today, as the Neil Armstrong Operations and Checkout Building in honor of the legendary astronaut and first man to set foot on the moon. The O&C was built in 1964. The facility has played a vital role in NASA’s spaceflight history. The high bay was used during the Apollo program to process and test the command, service and lunar modules. The facility is being used today to process and assemble Orion as the agency prepares to embark on the next giant leap in space exploration, sending astronauts to an asteroid and Mars.

A Giant Leap for Mankind: 45 years ago at 10:56 p.m. EDT Neil Armstrong is ready to plant the first human foot on another world. With more than half a billion people watching on television, he climbs down the ladder and proclaims: "That's one small step for (a) man, one giant leap for mankind." Buzz Aldrin joins him shortly, and offers a simple but powerful description of the lunar surface: "magnificent desolation." They explore the surface for two and a half hours, collecting samples and taking photographs. Today, we stand on a new horizon, poised to take the next giant leap-deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond.

The Eagle has landed! When it comes time to set Eagle down in the moon's Sea of Tranquility, Neil Armstrong improvises, manually piloting the ship past an area littered with boulders. During the final seconds of descent, Eagle's computer is sounding alarms. It turns out to be a simple case of the computer trying to do too many things at once, but as Buzz Aldrin will later point out, "unfortunately it came up when we did not want to be trying to solve these particular problems." When the lunar module lands at 4:18 p.m. EDT, only 30 seconds of fuel remain. Armstrong radios "Houston, Tranquility Base here. The Eagle has landed." Mission control erupts in celebration as the tension breaks, and a controller tells the crew "You got a bunch of guys about to turn blue, we're breathing again." Technology drives exploration and we're building on the Apollo program's accomplishments to test and fly transformative, cutting-edge technologies today for tomorrow's missions. As we develop and test the new tools of 21st century spaceflight on the human Path to Mars, we once again will change the course of history.

The Eagle Prepares to Land: It was 45 years ago today that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era. We stand on a new horizon, poised to take the next giant leap-deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond. This image is of the Apollo 11 Lunar Module Eagle in a landing configuration and was photographed in lunar orbit from the Command and Service Module Columbia. Inside the module were Commander Neil A. Armstrong and Lunar Module Pilot Buzz Aldrin. The long rod-like protrusions under the landing pods are lunar surface sensing probes. Upon contact with the lunar surface, the probes sent a signal to the crew to shut down the descent engine. Image Credit: NASA #nasa #apollo11 #apollo45# #pathtomars #nextgiantleap; -

Hubble Sees the Oldest Cluster in Milky Way Neighbor: This image shows NGC 121, a globular cluster in the constellation of Tucana (The Toucan). Globular clusters are big balls of old stars that orbit the centers of their galaxies like satellites — the Milky Way, for example, has around 150. NGC 121 belongs to one of our neighboring galaxies, the Small Magellanic Cloud (SMC). It was discovered in 1835 by English astronomer John Herschel, and in recent years it has been studied in detail by astronomers wishing to learn more about how stars form and evolve. Stars do not live forever — they develop differently depending on their original mass. In many clusters, all the stars seem to have formed at the same time, although in others we see distinct populations of stars that are different ages. By studying old stellar populations in globular clusters, astronomers can effectively use them as tracers for the stellar population of their host galaxies. With an object like NGC 121, which lies close to the Milky Way, Hubble is able to resolve individual stars and get a very detailed insight. NGC 121 is around 10 billion years old, making it the oldest cluster in its galaxy; all of the SMC's other globular clusters are 8 billion years old or younger. However, NGC 121 is still several billions of years younger than its counterparts in the Milky Way and in other nearby galaxies like the Large Magellanic Cloud. The reason for this age gap is not completely clear, but it could indicate that cluster formation was initially delayed for some reason in the SMC, or that NGC 121 is the sole survivor of an older group of star clusters. This image was taken using Hubble’s Advanced Camera for Surveys (ACS). Credit: ESA/Hubble & NASA, Acknowledgment: Stefano Campani #hubble #nasa #space #esa #universe #galaxy #galaxies #stars; -
We wish a happy 93rd birthday to original Mercury astronaut and former U.S. Senator John Glenn! Glenn wearing a Mercury pressure suit, is photographed at Cape Canaveral, Florida, during preflight training activities for the Mercury-Atlas 6 (MA-6) mission. Glenn made America's first manned Earth-orbital spaceflight on Feb. 20, 1962. Launched from Cape Canaveral (Florida) Launch Complex 14, he completed a successful three-orbit mission around the earth, reaching a maximum altitude (apogee) of approximately 162 statute miles and an orbital velocity of approximately 17,500 miles per hour. Glenn's "Friendship 7" Mercury spacecraft landed approximately 800 miles southeast of Cape Canaveral in the vicinity of Grand Turk Island. Mission duration from launch to impact was 4 hours, 55 minutes, and 23 seconds. Image Credit: NASA #happybirthday #nasa #space #mercury #friendship7 #astronaut; -
It's the pits! Lunar pits could one day shelter astronauts and reveal details of how 'Man in the Moon' formed. While the moon's surface is battered by millions of craters, it also has over 200 holes - steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from our Lunar Reconnaissance Orbiter (LRO) spacecraft. This is a spectacular high-sun view of the Mare Tranquillitatis pit crater revealing boulders on an otherwise smooth floor. This image from LRO is 400 meters (1,312 feet) wide, north is up.
