Build a NASA Satellite, Study the Universe Online

Thanks to a new online game from NASA, everyone can be an engineer or astronomer and build a satellite to uncover planets orbiting distant stars, unravel the secrets of a black hole, or tease out the faint glow of the early Universe.

NASA Goddard Space Flight Center in Greenbelt, Maryland, launched the new game, called “Build it Yourself: Satellite!” The Flash-based game, a learning tool for students and adults, is just a click away at http://www.jwst.nasa.gov/build.html.

“It’s fun to play and users will learn something about satellite instrumentation and optics, and how they are used to make scientific discoveries, as well about a large range of different existing astronomical missions,” said Maggie Masetti, NASA webmaster who authored and created the game. Artwork for the game is by Susan Lin and programmed by Kent deVillafranca.

Players begin by choosing what science their satellite will study; whether it’s black holes, star formation, early Universe, galaxies, or explanets. Then online engineers will decide the wavelengths – optical, infrared, ultraviolet – that their spacecraft will study. Finally, a choice must be made on the instruments and optics the mission will carry. Along the way, information bubbles explain each of the pieces you choose. After “launch,” the player sees what the satellite might look like and learn what real mission has data similar to what they created. Along the way, players learn about the different instruments added to various space missions and see the cosmic discoveries they might make.

Players can create a wide-range of satellites from small X-ray telescopes like NASA’s Rossi X-ray Timing Explorer, launched in 1995, to large orbiting telescopes like the NASA/ESA Hubble Space Telescope. Play it right, putting the right pieces together, and you can assemble a satellite superior to NASA’s huge, multi-mirrored James Webb Space Telescope, the original inspiration for the game. The Webb telescope currently is being built and will launch in 2018. With the Webb, scientists will be able to study the Universe nearly to the time of the Big Bang with infrared instruments.

Tropical Storm Debby Douses the Gulf

Satellite image of tropical storm "Debby" over the Gulf

The eastern Gulf of Mexico is getting lashed by tropical storm Debby, which whipped up tornado-spawning winds and dumped inches of rain across much of Florida, Mississippi, Alabama and southern Georgia over the weekend. NASA’s Aqua satellite acquired this image on June 23, just after the depression strengthened to full tropical storm status.

Born over the warm, moist air of the Gulf off the coast of Mississippi on Saturday afternoon, Debby quickly strengthened to storm status with sustained winds currently reported at over 60 mph. Slow-moving at a 6 mph crawl to the northeast, Debby continues to drench the Gulf state coasts with inches of rain — up to 10 to 20 inches projected for some areas. Major flooding has already become a problem and reports of tornadoes have been coming in since Sunday afternoon.

Debby will likely become a hurricane at some point, although her future path is still not entirely known.

Launched on May 4, 2002, NASA’s Aqua satellite specializes in keeping track of the movement of water around the planet in all its various forms. Find out more about the Aqua mission here.

Early Black Holes were Grazers Rather than Glutonous Eaters

Black holes powering distant quasars in the early Universe grazed on patches of gas or passing galaxies rather than glutting themselves in dramatic collisions according to new observations from NASA’s Spitzer and Hubble space telescopes.

A black hole doesn’t need much gas to satisfy its hunger and turn into a quasar, says study leader Kevin Schawinski of Yale “There’s more than enough gas within a few light-years from the center of our Milky Way to turn it into a quasar,” Schawinski explained. “It just doesn’t happen. But it could happen if one of those small clouds of gas ran into the black hole. Random motions and stirrings inside the galaxy would channel gas into the black hole. Ten billion years ago, those random motions were more common and there was more gas to go around. Small galaxies also were more abundant and were swallowed up by larger galaxies.”

Quasars are distant and brilliant galactic powerhouses. These far-off objects are powered by black holes that glut themselves on captured material; this in turn heats the matter to millions of degrees making it super luminous. The brightest quasars reside in galaxies pushed and pulled by mergers and interactions with other galaxies leaving a lot of material to be gobbled up by the super-massive black holes residing in the galactic cores.

Schawinski and his team studied 30 quasars with NASA’s orbiting telescopes Hubble and Spitzer. These quasars, glowing extremely bright in the infrared images (a telltale sign that resident black holes are actively scooping up gas and dust into their gravitational whirlpool) formed during a time of peak black-hole growth between eight and twelve billion years ago. They found 26 of the host galaxies, all about the size of our own Milky Way Galaxy, showed no signs of collisions, such as smashed arms, distorted shapes or long tidal tails. Only one galaxy in the study showed evidence of an interaction. This finding supports evidence that the creation of the most massive black holes in the early Universe was fueled not by dramatic bursts of major mergers but by smaller, long-term events.

“Quasars that are products of galaxy collisions are very bright,” Schawinski said. “The objects we looked at in this study are the more typical quasars. They’re a lot less luminous. The brilliant quasars born of galaxy mergers get all the attention because they are so bright and their host galaxies are so messed up. But the typical bread-and-butter quasars are actually where most of the black-hole growth is happening. They are the norm, and they don’t need the drama of a collision to shine.

“I think it’s a combination of processes, such as random stirring of gas, supernovae blasts, swallowing of small bodies, and streams of gas and stars feeding material into the nucleus,” Schawinski said.

Unfortunately, the process powering the quasars and their black holes lies below the detection of Hubble making them prime targets for the upcoming James Webb Space Telescope, a large infrared orbiting observatory scheduled for launch in 2018.

Huge Wildfires Burn on Opposite Sides of the Planet

The latest views of Earth from NASA’s Aqua and Terra satellites are looking a bit hazy from wildfires burning in wilderness areas of the United States and Siberia.

The above image acquired July 18 from the Moderate Resolution Imaging Spectroradiometer, or MODIS, aboard the Terra satellite, shows a whopping 198 wildfires burning across Siberia. You can view more of this huge fire at NASA’s Earth Observatory website. The fires have charred an area of more than 83 square kilometers. Some of the fires were started by people who lost control of agricultural fires but some fires were started by lightning.

Another NASA earth-observing satellite, Aqua, has taken dramatic images of the High Park Fire just west of Fort Collins, Colorado and the Whitewater-Baldy Complex Fire in southwestern New Mexico. The High Park Fire has grown to more than 235 square kilometers, burning 180 structures and leading to the death of one person. It has become one of the most destructive and largest fires in Colorado history. Thankfully, the

Besides measuring the smoke plume and fire extent, much can be learned using satellite images of wildfires. Types of vegetation can affect the type and color of smoke emitted by the wildfire. Grassland fires tend to burn quickly and give off carbon-rich black smoke. Forest fires where moisture is higher give off thicker smoke; a combination of organic rich ash and water vapor, that ranges in color from brown to bright white.

On the plus side for weather buffs, each of the fires have produced rare pyrocumulus, or fire clouds. Wildfires and volcanos can produce these dramatic clouds as intense heating causes the air to rise. As the rising air cools, water vapor in the ash cloud condenses just like a normal cloud. The ash particles provide nuclei for water to condense. Sometimes this moisture will fall back on the fire as rain. Dave Lipson, a meteorologist with the National Oceanic and Atmospheric Administration told the Denver Post that calm and clear weather along Colorado’s Front Range made the towering pyrocumulus cloud look especially menacing Tuesday. Tuesday afternoon, the lone fire cloud could be seen from 40 miles away from Denver.

See landing video below

The 2nd of the US Air Force’s top secret X-37B unmanned, reusable mini shuttles safely landed on Saturday, June 16, at 5:48 a.m. Pacific local time at Vandenberg Air Force Base, California to conclude a record setting classified 469 day experimental test flight in Earth orbit.

This was the first flight of OTV-2 and the second flight of the military’s classified X-37B Orbital Test Vehicle (OTV) test program for the U.S. Air Force Rapid Capabilities Office.

The reusable space plane is designed to be launched like a satellite and land on a runway like an airplane and NASA space shuttle. The X-37B is one of the newest and most advanced reentry spacecraft.

Here is the YouTube landing video released by the US Air Force:

OTV-2 was launched atop a United Launch Alliance Atlas V booster from Cape Canaveral Air Force Station, Fla., on March 5, 2011.

About 18 minutes after launch, the Air Force imposed a news blackout on the classified mission. Details about the cargo and experiments loaded aboard the Air Force orbital space plane are shrouded behind a veil of military security.

It is not known if the X-37B conducted reconnaissance activities during the test flight. It does have the capability to deploy satellites in space

The Air Force says the primary mission goal was to check out the vehicles capabilities and testing the ability to send experiments to space and return them safely.

The mission duration of well over one year far exceeded the 220-day mission duration of the first OTV craft and tested additional capabilities. Two OTV vehicles have been built by Boeing. The first craft, known as OTV-1, was the United States’ first unmanned vehicle to return from space and land on its own.

Previously, NASA space shuttles piloted by astronauts were the only space vehicles that had demonstrated the capability of returning to Earth and being reused.

“The vehicle was designed for a mission duration of about 270 days,” said Lt. Col. Tom McIntyre, the X-37B program manager in an Air Force statement. “We knew from post-flight assessments from the first mission that OTV-1 could have stayed in orbit longer. So one of the goals of this mission was to see how much farther we could push the on-orbit duration.”

The 11,000 pound state-of -the art reusable OTV space plane was built by Boeing and is about a quarter the size of a NASA space shuttle. It was originally developed by NASA but was transferred to the Defense Advanced Research Projects Agency (DARPA) in 2004.

“With the retirement of the space shuttle fleet, the X-37B OTV program brings a singular capability to space technology development,” McIntyre said. “The return capability allows the Air Force to test new technologies without the same risk commitment faced by other programs”

Among the cutting-edge technologies tested were the auto de-orbit capability, thermal protection tiles, and high-temperature components and seals.

“The X-37B’s advanced thermal protection and solar power systems, and environmental modeling and range safety technologies are just some of the technologies being tested,” said McIntyre. “Each mission helps us continue to advance the state-of-the-art in these areas.”

OTV-1 may lift off as early as October 2012 from Cape Canaveral.

“We look forward to the second launch of OTV-1 later this year and the opportunity to demonstrate that the X-37B is an affordable space vehicle that can be repeatedly reused,” said Paul Rusnock, Boeing vice president of Government Space Systems.

Voyager 1 Breaking Through the Borders of the Solar System

After almost 35 years traveling at over 35,000 mph, the venerable (and still operational!) Voyager 1 spacecraft is truly breaking through to the other side, crossing the outermost boundaries of our solar system into interstellar space — over 11 billion miles from home.

Data received from Voyager 1 — a trip that currently takes the information 16 hours and 38 minutes to make — reveal steadily increasing levels of cosmic radiation, indicating that the spacecraft is leaving the relatively protected bubble of the Sun’s influence and venturing into the wild and wooly space beyond.

From the JPL press release:

“The laws of physics say that someday Voyager will become the first human-made object to enter interstellar space, but we still do not know exactly when that someday will be,” said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena. “The latest data indicate that we are clearly in a new region where things are changing more quickly. It is very exciting. We are approaching the solar system’s frontier.”

The data making the 16-hour-38 minute, 11.1-billion-mile (17.8-billion-kilometer), journey from Voyager 1 to antennas of NASA’s Deep Space Network on Earth detail the number of charged particles measured by the two High Energy telescopes aboard the 34-year-old spacecraft. These energetic particles were generated when stars in our cosmic neighborhood went supernova.

“From January 2009 to January 2012, there had been a gradual increase of about 25 percent in the amount of galactic cosmic rays Voyager was encountering,” said Stone. “More recently, we have seen very rapid escalation in that part of the energy spectrum. Beginning on May 7, the cosmic ray hits have increased five percent in a week and nine percent in a month.”

This marked increase is one of a triad of data sets which need to make significant swings of the needle to indicate a new era in space exploration. The second important measure from the spacecraft’s two telescopes is the intensity of energetic particles generated inside the heliosphere, the bubble of charged particles the sun blows around itself. While there has been a slow decline in the measurements of these energetic particles, they have not dropped off precipitously, which could be expected when Voyager breaks through the solar boundary.

“When the Voyagers launched in 1977, the space age was all of 20 years old. Many of us on the team dreamed of reaching interstellar space, but we really had no way of knowing how long a journey it would be — or if these two vehicles that we invested so much time and energy in would operate long enough to reach it.”

Astronomers Measure Sunlight’s Shove

The physical force of sunlight on a moving asteroid has been measured by NASA scientists, providing information on how to better plot these Earth-passing worlds’ future paths.

First proposed by a 19-century Russian engineer, the Yarkovsky effect is the result of an object in space absorbing radiation from the Sun and emitting it as heat, thus creating a slight-but-measurable change in its movement (thanks to Newton’s first law of motion.)

By observing the 1999, 2005 and 2011 close passes of asteroid 1999 RQ36 with the Arecibo and Goldstone radar telescopes, astronomers were able to determine how much the trajectory of the half-kilometer-wide asteroid had changed.

The researchers’ findings revealed that RQ36 shifted by 160 km – about 100 miles – over the course of those 12 years. That deviation is attributed to the Yarkovsky effect. A miniscule force in and of itself, over time it has the ability to move entire worlds (albeit relatively small ones.)

“The Yarkovsky force on 1999 RQ36 at its peak, when the asteroid is nearest the Sun, is only about a half ounce — about the weight of three grapes on Earth,” said Steven Chesley of NASA’s Jet Propulsion Laboratory in Pasadena “Meanwhile, the mass of the asteroid is estimated to be about 68 million tons. You need extremely precise measurements over a fairly long time span to see something so slight acting on something so huge.”

Using measurements of the distance between the Arecibo Observatory in Puerto Rico and RQ36 during its latest pass in 2011 – a feat that was compared by team leader Michael Nolan to “measuring the distance between New York City and Los Angeles to an accuracy of two inches” – Chesley and his team were able to calculate all the asteroid’s near-Earth approaches closer than 7.5 million km (4.6 million miles) from the years 1654 to 2135. 11 such passes were found.

In addition, observation of 1999 RQ36 with NASA’s Spitzer Space Telescope found it to have about the same density as water – that’s light, for an asteroid.

Most likely, RQ36 is a “rubble-pile” form of asteroid, composed of a conglomeration of individual chunks of material held together by gravity.

These findings will be used by NASA scientists to help fine-tune the upcoming OSIRIS-REx mission, which is scheduled to launch in 2016 to rendezvous with 1999 RQ36 and return samples to Earth in 2023. Being a loose collection of rocks is expected to aid in the spacecraft’s sample retrieval process.

The findings were presented on May 19 at the Asteroids, Comets and Meteors 2012 meeting in Niigata, Japan. Read more here.

Clouds part for Transit of Venus from Princeton University

Transit of Venus snapped from Princeton University at 6:19 p.m. June 5, 2012. This image was taken with a Questar telescope at 6:19 p.m. as the clouds over Princeton, NJ parted to the delight of hundreds of onlookers and whole families.

Despite a horrendous weather forecast, the clouds parted – at least partially – just in the nick of time for a massive crowd of astronomy and space enthusiasts gathered at Princeton University to see for themselves the dramatic start of the Transit of Venus shortly after 6 p.m. EDT as it arrived at and crossed the limb of the Sun.

And what a glorious view it was for the well over 500 kids, teenagers and adults who descended on the campus of Princeton University in Princeton, New Jersey for a viewing event jointly organized by the Astrophysics Dept and the Amateur Astronomers Association of Princeton (AAAP), the local astronomy club to which I belong.

See Transit of Venus astrophotos snapped from Princeton, above and below by Astrophotographer and Prof. Bob Vanderbei of Princeton U and a AAAP club member.

It was gratifying to see so many children and whole families come out at dinner time to witness this ultra rare celestial event with their own eyes – almost certainly a last-in-a-lifetime experience that won’t occur again for another 105 years until 2117. The crowd gathered on the roof of Princeton’s Engineering Dept. parking deck – see photos

For the next two and a half hours until sunset at around 8:30 p.m. EDT, we enjoyed spectacular glimpses as Venus slowly and methodically moved across the northern face of the sun as the racing clouds came and went on numerous occasions, delighting everyone up to the very end when Venus was a bit more than a third of the way through the solar transit.

Indeed the flittering clouds passing by in front of Venus and the Sun’s active disk made for an especially eerie, otherworldly and constantly changing scene for all who observed through about a dozen AAAP provided telescopes properly outfitted with special solar filters for safely viewing the sun.

As part of this public outreach program, NASA also sent me special solar glasses to hand out as a safe and alternative way to directly view the sun during all solar eclipses and transits through your very own eyes – but not optical aids such as cameras or telescopes.

Altogether the Transit lasted 6 hours and 40 minutes for those in the prime viewing locations such as Hawaii – from where NASA was streaming a live Transit of Venus webcast.

You should NEVER look directly at the sun through any telescopes or binoculars not equipped with special eye protection – because that can result in severe eye injury or permanent blindness!

We in Princeton were quite lucky to observe anything because other astro friends and fans in nearby areas such as Philadelphia, PA and Brooklyn, NY reported seeing absolutely nothing for this last-in-a-lifetime celestial event.

Princeton’s Astrophysics Department organized a series of lectures prior to the observing sessions about the Transit of Venus and how NASA’s Kepler Space Telescope currently uses the transit method to detect and discover well over a thousand exoplanet and planet candidates – a few of which are the size of Earth and even as small as Mars, the Red Planet.

NASA’s Curiosity rover is currently speeding towards Mars for an August 6 landing in search of signs of life. Astronomers goal with Kepler’s transit detection method is to search for Earth-sized planets in the habitable zone that could potentially harbor life !

So, NASA and astronomers worldwide are using the Transit of Venus in a scientifically valuable way – beyond mere enjoyment – to help refine their planet hunting techniques.

Doing an outreach program for NASA, science writer Dr Ken Kremer distributes special glasses to view the transit of Venus across the sun during a viewing session on the top level of a parking garage at the E-quad at Princeton University to see the transit of Venus across the sun on Tuesday evening, June 5, 2012.

Historically, scientists used the Transit of Venus over the past few centuries to help determine the size of our Solar System.

See more event photos from the local daily – The Trenton Times – here

And those who stayed late after sunset – and while the Transit of Venus was still visibly ongoing elsewhere – were treated to an extra astronomical bonus – at 10:07 p.m. EDT the International Space Station (ISS) coincidentally flew overhead and was visible between more break in the clouds.

Of course clouds are no issue if you’re watching the Transit of Venus from the ISS or the Hinode spacecraft. See this Hinode Transit image published on APOD on June 9 and enhanced by Marco Di Lorenzo.

This week, local NY & NJ residents also had another extra special space treat – the chance to see another last-in-a-lifetime celestial event: The Transit of Space Shuttle Enterprise across the Manhattan Skyline on a seagoing voyage to her permanent new home at the Intrepid Sea, Air and Space Museum.

There’s a Hole in the Sky!

A vast hole in the cloud cover seen over the southern Pacific

[/caption]

Well, not the sky exactly, but definitely in the clouds!

This image, acquired by NASA’s Aqua satellite on June 5, shows an enormous oval hole in the clouds above the southern Pacific Ocean, approximately 500 miles (800 km) off the southwestern coast of Tasmania. The hole itself is several hundred miles across, and is the result of high pressure air in the upper atmosphere.

According to Rob Gutro of NASA’s Goddard Space Flight Center, “This is a good visible example of how upper-level atmospheric features affect the lower atmosphere, because the cloud hole is right under the center of a strong area of high pressure. High pressure forces air down to the surface blocking cloud formation. In addition, the altocumulus clouds are rotating counter-clockwise around the hole, which in the southern hemisphere indicates high pressure.”

The northwestern tip of Tasmania and King Island can be seen in the upper right of the image.

The Aqua mission is a part of the NASA-centered international Earth Observing System (EOS). Launched on May 4, 2002, Aqua has six Earth-observing instruments on board, collecting a variety of global data sets about the Earth’s water cycle. Read more about Aqua here.

Shuttle Enterprise Lands on the Deck of Intrepid in Manhattan

NASA’s Space Shuttle Enterprise lowered by crane onto the deck of the Intrepid on June 6, 2012.

[/caption]
NASA’s Space Shuttle Enterprise magnificently completed her final mission by making a historic landing on the deck of a retired aircraft carrier berthed in Manhattan- the Intrepid – as the first and only space shuttle to ever do so on a once-in-history spectacle befitting the Big Apple.

But instead of a piloted landing by air, Enterprise arrived afloat, atop a seagoing barge and was then hoisted and gently lowered for touch down on top of the Intrepid’s flight deck by a humongous seagoing crane accompanying the shuttle on a second barge at 4 p.m. EDT on Wednesday, June 6.

The Intrepid Sea, Air and Space Museum is the permanent new home of the Enterprise, NASA’s prototype shuttle – built in 1976 – that was used for a series of critical atmospheric approach and landing tests in the late 1970’s and that paved the way for building all the five shuttle orbiters that followed and the first launch by the Columbia in April 1981.

Enterprise embarked on a long and winding road to reach the Intrepid which I witnessed at points along the way. First she flew piggyback on top of NASA’s specially modified 747 Jumbo Jet from Dulles International Airport for a triumphant fly over tour of the New York Metropolitan region on April 27 before touching down at John F. Kennedy (JFK) International Airport.

Enterprise had been on public display at the Smithsonian’s National Air & Space Museum Annex in Virginia since 2003.

Then the shuttle took a two day cruise on June 3 and June 6, towed by a tugboat; departing from JFK on June 3 and voyaging through New York Harbor to the Statue of Liberty before making an intermediate stop at a port in Bayonne, New Jersey to switch to another larger barge. Along the way the orbiter suffered some minor damage to the right wing tip when wind gusts caused her to scrape against a railroad bridge.

After a 24 hour postponement due to poor weather, a repaired shuttle Enterprise at last put out to sea again on Wednesday morning, June 6, at about 9:45 a.m. for the very last time on the final leg of her thrilling final voyage.

Enterprise took one last beauty ride past the Statue of Liberty, Ground Zero and the Freedom Tower before sailing North up the Hudson River and past the Empire State Building on Manhattan’s West Side; enjoyed by throngs of onlookers and space enthusiasts lining the shores of New York and New Jersey.

She arrived at the Intrepid, located at Pier 86 at 46th Street and 12th Avenue, at about 1 p.m. accompanied by a flotillia of police and water spraying fire boats, ferries , sailboats and pleasure craft.

The giant lifting crane was maneuvered into position in between the Intrepid and Enterprise.

Over the next three hours, technicians carefully attached a yellow steel harness sling to the 150,000 pound orbiter at four points, two in the front and two in the rear. This was the same sling used to lift Enterprise onto and off the back of the 747 jet.

The 240 foot crane used to hoist Enterprise is the same one used to lift the US Airways jet piloted by hero captain Chesley “Sully” Sullenberger out of the Hudson after an emergency water landing near the same exact spot in January 2009 – where all the passengers and crew on board miraculously survived.

The dramatic pluck of the 75 ton Enterprise off the Weeks Marine barge started around 3:45 p.m. as the winds were gently gusting. Enterprise was raised some 75 feet and rotated nearly 180 degrees so her nose faced directly towards the Hudson River and the beautiful city and cliffs of Weehauken, in Hudson County, New Jersey, where I was watching and photographing from. Enterprise came to rest with wheels down around 4:02 p.m., pretty much exactly on time.

Finally the yellow sling was detached around 6 p.m. and Enterprise was dramatically exposed on the deck of the Intrepid in a beautiful sight for all to see.

But that gorgeous deck view didn’t last long because the museum quickly covered Enterprise with an inflatable pavilion to protect the delicate and precious orbiter from the weather and flying debris – and gawkers looking for free.

To see the Enterprise in all her glory now, you’ll have to pay $22 for admission to the museum and an extra $6 for the shuttle – or check my deck top photo below.

The museum is hastily constructing a temporary, climate controlled “Space Shuttle Pavilion” to house Enterprise. She will be open for public display starting on July 19.

Enterprise is named after the fictional starship in the world renowned and beloved TV science fiction series – “Star Trek”.
