Following the speed boosting slingshot of Earth on Wednesday, Oct. 9, that sent NASA’s Juno orbiter hurtling towards Jupiter, the probe has successfully transmitted back data and the very first flyby images despite unexpectedly going into ‘safe mode’ during the critical maneuver.

“Juno is transmitting telemetry today,” spokesman Guy Webster, of NASA’s Jet Propulsion Lab (JPL), told me in a phone interview late today (Oct. 10), as Juno continues sailing on its 2.8 Billion kilometer (1.7 Billion mile) outbound trek to the Jovian system.

The new images of Earth captured by the Junocam imager serves as tangible proof that Juno is communicating.

“Juno is still in safe mode today (Oct. 10),” Webster told Universe Today.

“Teams at mission control at JPL and Lockheed Martin are actively working to bring Juno out of safe mode. And that could still require a few days,” Webster explained.

Lockheed Martin is the prime contractor for Juno.

The initial raw images of Earth snapped by the craft’s Junocam imager were received by ground stations late today.

Juno performed a crucial swingby of Earth on Wednesday that accelerated the probe by 16330 MPH to enable it to arrive in orbit around Jupiter on July 4, 2016.

However the gravity assist maneuver did not go entirely as planned.

Shortly after Wednesday’s flyby, Juno Project manager Rick Nybakken, of JPL, told me in a phone interview that Juno had entered safe mode but that the probe was “power positive and we have full command ability.”

“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken explained.

The safe mode was triggered while Juno was in an eclipse mode, the only eclipse it will experience during its entire mission.

The Earth flyby did accomplish its objective by placing the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.

“We are on our way to Jupiter as planned!”

“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” Nybakken stated.

Juno’s closest approach was over South Africa at about 561 kilometers (349 miles).

During the flyby, the science team also planned to observe Earth using most of Juno’s nine science instruments since the slingshot also serves as a key test of the spacecraft systems and the flight operations teams.

Juno also was to capture an unprecedented new movie of the Earth/Moon system.

Many more images were snapped and should be transmitted in coming days that eventually will show a beautiful view of the Earth and Moon from space.

“During the earth flyby we have most of our instruments on and will obtain a unique movie of the Earth Moon system on our approach, Juno principal investigator Scott Bolton told me. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.

“We will also calibrate instuments and measure earth’s magnetosphere, obtain closeup images of the Earth and the Moon in UV [ultraviolet] and IR [infrared],” Bolton explained to Universe Today.

Juno is approaching the Earth from deep space, from the sunlit side.

“Juno will take never-before-seen images of the Earth-moon system, giving us a chance to see what we look like from Mars or Jupiter’” says Bolton.

Here is a description of Junocam from the developer – Malin Space Science Systems

“Like previous MSSS cameras (e.g., Mars Reconnaissance Orbiter’s Mars Color Imager) Junocam is a “pushframe” imager. The detector has multiple filter strips, each with a different bandpass, bonded directly to its photoactive surface. Each strip extends the entire width of the detector, but only a fraction of its height; Junocam’s filter strips are 1600 pixels wide and about 155 rows high. The filter strips are scanned across the target by spacecraft rotation. At the nominal spin rate of 2 RPM, frames are acquired about every 400 milliseconds. Junocam has four filters: three visible (red/green/blue) and a narrowband “methane” filter centered at about 890 nm.”

Juno launched atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.

During a one year long science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution.

NASA’s Juno probe Gets Gravity Speed Boost during Earth Flyby But Enters ‘Safe Mode’

The first color reconstruction of the Moon by Adam Hurcewicz

Developing story – NASA’s Juno-bound Jupiter orbiter successfully blazed past Earth this afternoon (Oct. 9) and gained its huge and critical gravity assisted speed boost that’s absolutely essential to reach the Jovian system in 2016.

However, Juno’s project manager Rick Nybakken told me moments ago that the Juno spacecraft unexpectedly entered ‘safe mode’ during the fly by maneuver and the mission teams are assessing the situation.

But the very good news is “Juno is power positive at this time. And we have full command ability,” said Nybakken in an exclusive phone interview with me.

“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken told me. Nybakken is the Juno mission project manager at NASA’s Jet Propulsion Lab in Pasadena, CA.

Furthermore, the Earth flyby did place the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.

“We are on our way to Jupiter as planned!”

“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is.”

Juno’s closest approach was over South Africa at about 500 kilometers (350 miles).

“Juno hit the target corridor within 2 km of the aim point,” Nybakken elaborated to Universe Today.

Juno needs the 16,330 mph velocity boost from the Earth swingby because the Atlas V launcher was not powerful enough to hurtle the 8000 pound (3267 kg) craft fast enough on a direct path to Jupiter.

And the team is in full radio contact with the probe. Safe mode is a designated protective state.

“Prior to the eclipse, which was a few minutes earlier than closest approach, the spacecraft was ‘nominal’. When we came out of the eclipse Juno was in safe mode,” Nybakken stated.

“We are going through safe mode diagnostics steps right now.”

“We have established full uplink and downlink. And we have full command ability of the spacecraft.”

First JunoCam image of the day! Taken at 11:07 UTC when Juno was 206,000 Kilometers from the Moon.

Speed boosting slingshots have been used on numerous planetary missions in the past

The spacecraft’s power situation and health is as good as can be expected.

“Juno is power positive at this time and sun pointed and stable. So we are very pleased about that,” Nybakken explained.

I asked if Juno had ever entered ‘safe mode’ before?

“We have never been in safe mode before. We are in a safe, stable state.”

“We are investigating this,” said Nybakken.

Today’s (Oct. 9) Earth flyby is the only time the spacecraft experiences an eclipse period during Juno’s entire five year and 1.7 Billion mile (2.8 Billion km) trek to Jupiter, the largest planet in our solar system.

When it finally arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant.

NASA’s Juno spacecraft blasted off atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.

The science team had also hoped to use the on board JunoCam imager to make a cool and unprecedented movie of Earth as it approached from the sunlit side – showing the passage as though you were a visitor from outer space.

I had an inkling that something might be amiss this afternoon when no images of Earth appeared on the Juno mission website.

So I asked the status.

“We don’t know yet if any images of Earth were collected. We hope to know soon.”

Juno flew past the Moon before the gravity assist slingshot with Earth. And it did manage to successfully capture several lunar images. See the images herein.

Read more about Juno in my flyby preview story – here.

Note: Due to the continuing chaos resulting from the US government partial shutdown caused by gridlocked politico’s in Washington DC, NASA public affairs remains shut down and is issuing no official announcements on virtually anything related to NASA! This pertains to Juno’s flyby, LADEE’s lunar arrival on Oct. 6, MAVEN’s upcoming launch in November, Cygnus at the ISS, and more!

Stay tuned here for continuing Juno, LADEE, MAVEN and more up-to-date NASA news.

Could Juno’s Path Near Earth Uncover A Flyby Mystery?

Every so often, engineers send a spacecraft in Earth’s general direction to pick up a speed boost before heading elsewhere. But sometimes, something strange happens — the spacecraft’s speed varies in an unexpected way. Even stranger, this variation happens only during some Earth flybys.

“We detected the flyby anomaly during Rosetta’s first Earth visit in March 2005,” stated Trevor Morley, a flight dynamics specialist at the European Space Agency’s European Space Operations Centre in Darmstadt, Germany.

“Frustratingly, no anomaly was seen during Rosetta’s subsequent Earth flybys in 2007 and 2011. This is a real cosmic mystery that no one has yet figured out.”

The phenomenon has been noticed in several spacecraft (both from ESA and NASA) since 1990. NASA’s NEAR asteroid spacecraft in January 1998 had the largest change, of 13 millimeters (0.5 inches) a second. The smallest variations, with NASA’s Saturn-bound Cassini in 1999 and Mercury-pointing MESSENGER in 2005, were below the threshold of measurement.

ESA won’t even speculate on what’s going on. “The experts are stumped,” the agency says in a press release.

Those experts, however, do have some ideas on how to track that down. ESOC plans to watch Juno’s flyby using a 35 meter deep-space dish in Malargüe, Argentina, as well as a 15-meter dish in Perth, Australia

“The stations will record highly precise radio-signal information that will indicate whether Juno speeds up or slows down more or less than predicted by current theories,” ESA states.

What do you think is going on? Let us know in the comments!

Details on how to watch via Slooh – see below [/caption]

NASA’s solar powered Jupiter-bound Juno orbiter is careening towards Earth for an absolutely critical gravity assisted fly by speed boost while capturing an unprecedented movie view of the Earth/Moon system – on its ultimate quest to unveiling Jupiter’s genesis!

“Juno will flyby Earth on October 9 to get a gravity boost and increase its speed in orbit around the Sun so that it can reach Jupiter on July 4, 2016,” Juno chief scientist Dr. Scott Bolton told Universe Today in an exclusive new Juno mission update – as the clock is ticking to zero hour. “The closest approach is over South Africa.”

All this ‘high frontier’ action comes amidst the utterly chaotic US government partial shutdown, that threatened the launch of the MAVEN Mars orbiter, has halted activity on many other NASA projects and stopped public announcements of the safe arrival of NASA’s LADEE lunar orbiter on Oct. 6, Juno’s flyby and virtually everything else related to NASA!

Bolton confirmed that the shutdown fortunately hasn’t altered or killed Juno’s flyby objectives. And ops teams at prime contractor Lockheed Martin have rehearsed and all set.

And some more good news is that Slooh will track the Juno Earth Flyby “LIVE” – for those hoping to follow along. Complete details below!

“The shutdown hasn’t affected our operations or plans, Bolton told me. Bolton is Juno’s principal investigator from the Southwest Research Institute (SwRI), San Antonio, Texas.

“Juno is 100% healthy.”

“But NASA is unable to participate in our public affairs and press activities,” Bolton elaborated.

97% of NASA’s employees are furloughed – including public affairs – due to the legal requirements of the shutdown!

Juno will also capture an unprecedented new movie of the Earth/Moon system.

A full up science investigation of our Home Planet by Juno is planned, that will also serve as a key test of the spacecraft and its bevy of state of the art instruments.

“During the earth flyby we have most of our instruments on and will obtain a unique movie of the Earth Moon system on our approach.

“We will also calibrate instuments and measure earth’s magnetosphere, obtain closeup images of the Earth and the Moon in UV [ultraviolet] and IR [infrared],” Bolton explained to Universe Today.

The flyby will accelerate the spacecraft’s velocity by 16,330 mph.

Where is the best view of Juno’s flyby, I asked?

“The closest approach is over South Africa and is about 500 kilometers [350 miles],” Bolton replied.

The time of closest approach is 3:21 p.m. EDT (12:21 PDT / 19:21 UTC) on Oct. 9, 2013

Watch this mission produced video about Juno and the Earth flyby:

Video caption: On Oct. 9, 2013, NASA’s Jupiter-bound Juno spacecraft is making a quick pass to get a gravity boost from the mother planet. Dr. Scott Bolton of Southwest Research Institute® is the Juno mission principal investigator, leading an international science team seeking to answer some fundamental questions about the gas giant and, in turn, about the processes that led to formation of our solar system.

NASA’s Juno spacecraft blasted off atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 to begin a 2.8 billion kilometer science trek to discover the genesis of Jupiter hidden deep inside the planet’s interior.

Juno is on a 5 year and 1.7 Billion mile (2.8 Billion km) trek to the largest planet in our solar system. When it arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant.

During a one year science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s genesis and evolution.

The goal is to find out more about the planets origins, interior structure and atmosphere, observe the aurora, map the intense magnetic field and investigate the existence of a solid planetary core

Why does Juno need a speed boost from Earth?

“A direct mission to Jupiter would have required about 50 percent more fuel than we loaded,” said Tim Gasparrini, Juno program manager for Lockheed Martin Space Systems, in a statement.

“Had we not chosen to do the flyby, the mission would have required a bigger launch vehicle, a larger spacecraft and would have been more expensive.”

Viewers near Cape Town, South Africa will have the best opportunity to view the spacecraft traveling across the sky.

Juno itself will most likely not be visible to the unaided eye, but binoculars or a small telescope with a wide field should provide an opportunity to view, according to a Slooh statement.

Slooh will track Juno live on October 9th, 2013.

Check here for international starting times: http://goo.gl/7ducFs – and for the Slooh broadcast hosted by Paul Cox.

Viewers can view the event live on Slooh.com using their computer or mobile device, or by downloading the free Slooh iPad app in the iTunes store. Questions can be asked during the broadcast via Twitter by using the hashtag #nasajuno -says Slooh.

Amidst the government shutdown, Juno prime contractor Lockheed Martin is working diligently to ensure the mission success.

Because there are NO 2nd chances!

“The team is 100 percent focused on executing the Earth flyby successfully,” said Gasparrini.

“We’ve spent a lot of time looking at possible off-nominal conditions. In the presence of a fault, the spacecraft will stay healthy and will perform as planned.”

Stay tuned here for continuing Juno, LADEE, MAVEN and more up-to-date NASA news.

And be sure to check back here for my post-flyby update.

What’s not at all clear is whether Juno will detect any signs of ‘intelligent life’ in Washington D.C.!

Awesome Photo: Aurora, Airglow, City Lights and Shining Stars

Photo taken by ESA astronaut Luca Parmitano on Sept. 5, 2013 (ESA/NASA)

Italian astronaut Luca Parmitano shares a lot of fantastic photos taken from his privileged position 260 miles up aboard the Space Station, orbiting the planet 16 times a day. This is his latest, a stunning view of nighttime city lights spread out beneath a glowing dome of ghostly airglow and shimmering aurorae, with a backdrop of brightly shining stars. The dark silhouette of a solar array is in the foreground at right.

And in case you were wondering, yes, astronauts certainly can see stars while in space. A lot of them, in fact. (Except up there, they don’t twinkle… but they’re no less beautiful!)

“Every time we look into the sky and we admire the same stars, we share the same experience with all those who still know how to dream.”

– Luca Parmitano

Luca Parmitano is the first of ESA’s new generation of astronauts to fly into space. The current mission, Volare, is ESA’s fifth long-duration Space Station mission. During his six-month-long stay aboard the ISS, Luca has been conducting research for ESA and international partners as well as taken many photographs of our planet, sharing them on Twitter, Flickr, and the Volare mission blog.

Here’s Your Chance To Help Blend Earth And Mars Rocks

The official poster of the World Space Week Association 2013 campaign. Credit: World Space Week Association

The organizers of the World Space Week Association are working to create an “Earth Master Sample”, and they want your help. Anyone worldwide can send the association a fist-sized rock from their locale.

Next will come the interplanetary recipe magic: Once the samples arrive, a tiny bit of each rock will be procured and ground into a powder. The powder will be mixed together, with a dash of Mars meteorite added in. Next, a crystal company (Swarovski) will melt down the combination into 100 crystals.

These crystals will be shown off at Yuri’s Night celebrations on April 12, 2014; the event commemorates the first human spaceflight by Yuri Gagarin, which took place on that day in 1961. More importantly, the organizers said, the crystals will stand as a symbol of the importance of doing “planetary analog” research on Earth to better understand the conditions on other planets.

Are Earthlings really Martians ? Did life arise on Mars first and then journey on meteors to our planet and populate Earth billions of years ago? Earth and Mars are compared in size as they look today. — Earth and Mars are compared in size as they look today.

“By participating in the Earth Master Sample campaign, people can show their support for analog exploration and their aspiration to see Mars exploration continue through sample return missions and, eventually, human expeditions,” stated Remco Timmermans, the association’s executive director.

Here are the instructions (reproduced below verbatim from the association):

Take a picture of the sample site and a scale (e.g. classmate, family member etc.) from at least 10m distance
Take a close-up picture with a scale (e.g. hammer, pen, etc)
Note your geographical location (e.g. 31°22.363 N 4°4.357 W)
Take a fist-sized rock sample. (No soil samples, no sand please).
Put the sample into a clean plastic bag. IMPORTANT: Label the sampling bag with: date (DD/MM/YY) + Time (HH:MM) + geographical coordinates. (e.g. 17AUG13 17:22, 47.234 N / 11.234 E)
Send an email to [email protected] listing the geographical location, the two pictures and the details of a contact person.
Mail the rock-sample to: Austrian Space Forum / Earth Master Sample Project, Sillufer 3a, 6020 Innsbruck, AUSTRIA
Deadline: 15. November 2013 (for arrival of rocks at the Austrian Space Forum)

This year, World Space Week runs from Oct. 4 to Oct. 10, 2013. The association will hold events at the Austrian Space Forum in Innsbruck, Austria. Here’s more information on their activities.

Could The U.S. Government Shutdown Hammer Earth and Mars Missions?

Artist's conception of the Mars 2020 rover. Credit: NASA

As Day 2 of the United States government shutdown continues, some short-term effects are already in evidence when it comes to Earth and space.

Most of the NASA and National Oceanic and Atmospheric Administration (NOAA) websites are offline. Social media updates are silent. At NASA, 97% of agency employees are off work and media reports indicate that 55% of NOAA’s employees are furloughed.

If the shutdown lasts for very long, however, long-term programs could feel the pain. This includes a couple of Mars missions NASA is developing, as well as Earth-based climate research and satellite observation from NOAA.

Mars 2020

A twin rover to Mars Curiosity, called Mars 2020 for now, is expected to leave for the Red Planet in 2020 and do investigations into past life and habitability. Planning is still in the early stages, but an announcement of opportunity for science investigators was supposed to happen on Oct. 8. Notices of intent were due Oct. 15.

“The preproposal conference, scheduled for 10/8, may be rescheduled and the due date for NOIs (currently 10/15) could be delayed, if the government is still shut down closer to those dates,” NASA officials wrote in an update before the shutdown on Monday.

MAVEN

As widely reported yesterday, the next Mars orbiter from NASA is expected to lift off from Earth on Nov. 18. Now, however, preparatory work has ceased and there is some concern from team members that it will miss the launch window, which extends into December. At worst, this means MAVEN’s launch could be delayed until 2016, when the next opportunity opens.

“The hardware is being safed, meaning that it will be put into a known, stable, and safe state,” Bruce Jakosky, MAVEN’s principal investigator, told Universe Today‘s Ken Kremer yesterday. “We’ll turn back on when told that we can. We have some margin days built into our schedule.”

NOAA

As with NASA, NOAA is keeping up with mission-critical activities — which in their case, includes weather forecasting. Long-term climate research, however, is reportedly being shelved.

“For example, Harold Brooks, a top tornado researcher who works at the National Severe Storms Laboratory in Norman, Okla., reported his furlough notice on Facebook on Tuesday,” Climate Central wrote on Oct. 1. “Much of the staff at NOAA’s Earth Systems Research Lab and the Geophysical Fluid Dynamics Laboratory, except for positions related to maintaining computing resources, have also been furloughed. Those two labs are heavily involved in NOAA’s climate research programs.”

Observers are also worried that a lengthy shutdown could push back the time when new weather satellites become available. There have been multiple reports about a “weather satellite gap” coming in the United States as many of NOAA’s geostationary and polar-orbiting satellites are nearing the end of their expected lives. The Subcommittees on Oversight and Environment held hearings into this issue in September.

What’s still online?

These are some of the programs that are still happening at NASA and NOAA:

NASA:

Bare-bones management on programs such as the International Space Station and several robotic missions that are already in operation (such as the Lunar Atmosphere and Dust Environment Explorer (LADEE).
Certain missions are in critical phases that could be hurt if work stops, such as the James Webb Space Telescope, which is undergoing cryogenic testing on some of its instruments.
Several missions run out of the Jet Propulsion Laboratory and Applied Physics Laboratory are still running as usual, according to the Planetary Society, as these receive contract money from NASA; this means Mars Curiosity is still working, for example.
The Mars Reconnaissance Orbiter’s HiRISE camera is still snapping pictures, its Twitter account reported, which is positive given that it was intended to snap shots of Comet ISON during its closest approach to Mars yesterday.
The decades-long Landsat Earth observation program is still operating, according to The Atlantic, with data being sent back to Earth as usual. The difference is this information won’t be packaged as usual until government operations restart.

NOAA (all information according to this Department of Commerce document):

The Office of Oceanic and Atmospheric Research will keep 73 employees on board “to ensure continuity of crucial long-term historical climate records, and real-time regular research to support ongoing weather and air quality prediction services,” NOAA said.
184 employees will stay with the Environmental Satellite and Data Information Service for command and control of several satellites for NOAA and the Department of Defense.
474 employees will remain with the National Marine Fisheries Service. 174 are funded in another form besides appropriations. The others are a mix of law enforcement, fisheries management and property protection officials.
490 employees are with the Office of Marine and Aviation Operations for observational data collection related to weather forecasting.
173 employees are with the National Ocean Service. 17 are funded outside of appropriations, while the 156 remaining “are required to protect against imminent and significant threats to life and property by supporting safe maritime commerce in U.S. waters, including real-time water level data for ships entering U.S. ports, critical nautical chart updates, and accurate position information,” NOAA stated. Some are also monitoring marine health aspects such as algal blooms.
There are 19 IT-related employees and 20 employees providing support services.
The large bulk of employees still at work, 3,935 people, are with the National Weather Service to keep up weather forecasting.

There’s no word yet on when government employees could go back to work. Congress representatives are jousting over the implementation of a spending bill to keep the money flowing to government departments. One big issue: whether to include the Affordable Care Act, sometimes dubbed Obamacare, in the bill.

Another deadline is looming, too. Treasury Secretary Jack Lew has warned repeatedly that on Oct. 17, if the debt ceiling is not raised, the United States government may default on some financial obligations.

How Long Will Life Survive on Earth?

A powerful X-class solar flare erupting on the sun on July 6, 2012 photographed by the Solar Dynamics Observers. Credit: NASA

Life has existed on Earth for billions of years, appearing shortly after the planet had cooled and liquid water became available.

From the first bacteria to the amazingly complex animals we see today, life has colonized every corner of our planet.

As you know, our Sun has a limited lifespan.

Over the next 5 billion years, it will burn the last of its hydrogen, bloat up as a red giant and consume Mercury and Venus.

This would be totally disastrous for local flora and fauna, but all life on the surface of the Earth will already be long gone.

In fact, we have less than a billion years to enjoy the surface of our planet before it becomes inhospitable.

Because our Sun… is heating up.

You can’t feel it over the course of a human lifetime, but over hundreds of millions of years, the amount of radiation pouring out of the Sun will grow.

This will heat the surface of our planet to the point that the oceans boil.

At the core of the Sun, the high temperatures and pressures convert hydrogen into helium. For every tonne of material the Sun converts, it shrinks a bit making the Sun denser, and a little hotter.

Over the course of the next billion years or so, the amount of energy the Earth receives from the Sun will increase by about 10%. Which doesn’t sound like much, but it means a greenhouse effect of epic proportions.

A TerraSAR-X stripmap image from 23 April 2009. The larger icebergs are bright, while smaller icebergs are capsized and appear as dark blocks. The inset shows two superimposed Envisat ASAR images from 24 and 27 April. The region outlined in red indicates the area of the TerraSAR-X image. Credits: DLR, ESA (Annotations by A. Humbert, Münster University — A TerraSAR-X stripmap image of icebergs.

Whatever is left of the ice caps will melt, and the water itself will boil away, leaving the planet dry and parched. Water vapor is a powerful greenhouse gas, this will drive the temperatures even hotter.

Plate tectonics will shut down, and all the carbon will be stripped from the atmosphere.

It’ll be bad.

As temperatures rise, complex lifeforms will find life on Earth less hospitable. It will seem as if evolution is running in reverse, as plants and animals die off, leaving the invertebrates and eventually just microbial life.

This rise in temperature will be the end of life on the surface of Earth as we know it.

Still, there are reserves of water deep underground which will continue to protect microbial life for billions of years.

Perhaps they’ll experience that final baking when the Sun does reach the end of its life.

Even a few hundred million years is an incomprehensible amount of time compared to the age of our civilization.

If humanity does survive well into the future, is there anything we could do about this problem?

As the Sun heats up, making Earth inhospitable, it heats up the rest of the Solar System too. Frozen worlds in the Solar System will melt, becoming more habitable.

It’s possible that future civilizations could relocate to the asteroid belt, or the moons of Saturn. We could try something even more radical: move the Earth.

By carefully steering asteroids so they barely miss us, an advanced civilization could distort the Earth’s orbit, relocating our planet further from the Sun.

As the Sun heats up, our planet would be continuously repositioned so the surface temperature stays roughly the same. Of course, this would be tricky business. Make the wrong move, and you’re facing the frigid cold of the outer Solar System.

So there’s no need to panic. Life here has a few hundred million years left; a billion, tops. But if we want to continue on for billions of years, we’ll want to add solar heating to our growing list of big problems.

Today (Sept. 29) was a doubly historic day for private spaceflight! And a boon to NASA as well!

Early this morning the Orbital Sciences Cygnus commercial cargo ship docked at the International Space Station (ISS) speeding along some 250 miles (400 km) overhead in low Earth orbit.

Barely a few hours later the Next Generation commercial SpaceX Falcon 9 rocket soared to space on a demonstration test flight from the California coast carrying a Canadian satellite to an elliptical earth orbit.

These missions involved the dramatic maiden flights for both Cygnus and the upgraded Falcon 9.

And both were high stakes endeavors, with literally billions of dollars and the future of commercial spaceflight, as well as the ISS, on the line. Their significance cannot be overstated!

Both Cygnus and Falcon 9 were developed with seed money from NASA in a pair of public-private partnerships between NASA and Orbital Sciences and SpaceX under NASA’s COTS commercial transportation initiative aimed at fostering the development of America’s private space industry to deliver critical and essential supplies to the ISS.

The powerful new Falcon 9 will also be used to send cargo to the ISS.

America completely lost its capability to send humans and cargo to the ISS when NASA’s space shuttles were retired in 2011. Orbital Sciences and SpaceX were awarded NASA contracts worth over $3 Billion to restore the unmanned cargo resupply capability over 20 flights totally.

The Cygnus spacecraft put on a spectacular space ballet – and was no worse for the wear after its docking was delayed a week due to an easily fixed communications glitch.

Cygnus is a privately developed resupply vessel built by Orbital Sciences Corp and Thales Alenia Space that is a crucial railroad to orbit for keeping the massive orbital lab complex well stocked with everyday essentials and science experiments that are the purpose of the ISS.

Cygnus was grappled in free drift by Expedition 37 space station astronauts Luca Parmitano and Karen Nyberg at about 7 a.m. EDT Sunday morning.

The pair were working at two robotics work stations from inside the Cupola and Destiny modules. They used the stations 57 foot long Canadarm2 to snare Cygnus at a distance of about 30 feet (10 meters). They gradually motioned the arm closer.

Running a bit ahead of schedule they successfully berthed Cygnus at the earth facing port of the Harmony module by about 8:44 a.m. EDT.

Cygnus was launched to orbit on its inaugural flight on Sept. 18 atop Orbital’s commercial Antares rocket from NASA’s Wallops Flight Facility on the Eastern shore of Virginia.

Sept. 22 had been the initially targeted station docking date for this demonstration mission.

Hatches to Cygnus will be opened on Monday, Sept. 30 after completing leak checks.

“Today, with the successful berthing of the Orbital Sciences Cygnus cargo module to the ISS, we have expanded America’s capability for reliably transporting cargo to low-Earth orbit, “ said NASA Admisistrator Charles Bolden in a statement.

“It is an historic milestone as this second commercial partner’s demonstration mission reaches the ISS, and I congratulate Orbital Sciences and the NASA team that worked alongside them to make it happen.”

“Orbital joins SpaceX in fulfilling the promise of American innovation to maintain America’s leadership in space. As commercial partners demonstrate their new systems for reaching the Station, we at NASA continue to focus on the technologies to reach an asteroid and Mars,” said Bolden.

Cygnus delivers about 1,300 pounds (589 kilograms) of cargo, including food, clothing, water, science experiments, spare parts and gear to the Expedition 37 crew.

The upgraded SpaceX Falcon 9 blasted off from Space Launch Complex 4 at Vandenberg Air Force Base in California at 9 a.m. PDT (12 p.m. EDT).

Here’s a video of the launch:

It successfully deployed Canada’s 1,060 pound (481 kg) Cascade, Smallsat, and Ionospheric Polar Explorer (CASSIOPE) weather satellite and several additional small satellites.

This powerful new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of the new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines and can therefore boost a much heavier cargo load to the ISS and beyond.

The next generation Falcon 9 is a monster. It’s much taller than a standard Falcon 9 – some 22 stories vs. 13.

It could launch from Cape Canaveral as early as this Fall.

Pakistan’s “Earthquake Island” Seen From Space

Mud island off the coast of Gwadar imaged by NASA's EO-1 satellite on Sept. 26, 2013

On the afternoon of Tuesday September 24, 2013, a 7.7-magnitude earthquake struck Balochistan province in southern Pakistan, causing widespread destruction across several districts during more than 2 minutes of powerful tremors and shaking. Sadly at least 400 people were killed (some reports say 600) and over 100,000 have been left homeless. But a weirder — if much less tragic — effect of the quake that was soon reported worldwide was the sudden appearance of a new island off the coast, a mound of mud and bubbling methane seeps rising nearly 20 meters (70 feet) from the ocean surface.

The image above, taken by NASA’s Earth Observing-1 satellite, shows the newly-formed mud island a kilometer (0.6 miles) off the Gwadar coast.

According to an article by the Pakistani news site Dawn.com, the 250-by-100-foot-long pile of mud and rocks is leaking flammable gases.

“Our team found bubbles rising from the surface of the island which caught fire when a match was lit and we forbade our team to start any flame,” said Mohammad Danish, a marine biologist from Pakistan’s National Institute of Oceanography. “It is methane gas.”

Pakistan’s many earthquakes are the result of collisions between the Indian, Arabian, and Eurasian tectonic plates. These sorts of mud volcanoes are not particularly unusual after large quakes there… it just so happened that this one occurred near a populated coast and in relatively shallow water. (Source)

(In fact two days later another mud island was spotted off the coast of the nearby coastal town of Ormara.)

The mud volcano, which is being called “Zalzala Jazeera” (earthquake island) is not expected to last long. Wave action will eventually sweep the sediment away over the course of several months. (Dawn.com.)

Unfortunately earthquake relief efforts in the remote Taliban-dominated region are being hampered by militant activity.
