The clock is ticking down relentlessly towards “The mother of all slingshots” – the critical engine firing intended to hurl India’ Mars Orbiter Mission (MOM) probe on her ten month long interplanetary cruise to the Red Planet.
Engineers at the Indian Space Research Organization’s (ISRO) Mission Operations Complex at Bangalore are now just hours away from sending the commands that will ignite MOMs’ liquid fueled main engine for TMI – the Trans Mars Insertion maneuver that will propel MOM away from Earth forever and place the craft on an elliptical trajectory to the Red Planet.
“Performance assessment of all subsystems of the spacecraft has been completed,” reports ISRO.
The do or die 1351 second burn is slated to begin at 00:49 hrs IST tonight – on Dec. 1 Indian local time.

The most recent orbit raising maneuver occurred at 01:27 hrs (IST) on Nov 16, 2013 with a burn time of 243.5 seconds increased the apogee from 118,642 km to 192,874 km.
Tonight burn is MOM’s final one around Earth and absolutely crucial for setting her on course for Mars.
If all goes well the $69 million MOM spacecraft reaches the vicinity of Mars on 24 September 2014.
MOM was the first of two Earth missions to Mars launched this November.
NASA’s $671 Million MAVEN orbiter launched as scheduled on Nov. 18, from Cape Canaveral, Florida and arrives at Mars on Sept. 22, 2014, about two days before MOM.
Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.
Stay tuned here for continuing MOM and MAVEN news and Ken’s MAVEN and SpaceX Falcon 9 launch reports from on site at the Kennedy Space Center press center and Cape Canaveral Air Force Station, Florida.

CAPE CANAVERAL, FL – MOM is looking at you, kid!
And if the spectacular new image of billions of Earth’s children captured by India’s Mars Orbiter Mission (MOM) is any indication (see above), then we can expect absolutely gorgeous scenes of the Red Planet once the groundbreaking probe arrives there in September 2014.
But despite all that’s been accomplished so far, the space drama is still in its infant stages – because MOM still needs to ignite her thrusters this weekend in order to achieve escape velocity, wave good bye to Earth forever and eventually say hello to Mars!
The picture – snapped from Earth orbit – is focused on the Indian subcontinent, the probes origin.
MOM has captured the imagination of space enthusiasts worldwide.
During testing of the MOM probes payloads – while it’s still flying in a highly elliptical orbit around our Home Planet – engineers from India’s space agency turned the crafts camera homewards to capture the “First ever image of Earth Taken by Mars Color Camera,” according to the Indian Space Research Organization (ISRO).
The beautiful image was taken on Nov. 20 at around 1350 hrs (IST) from a height of almost 70,000 km above earth and has a spatial resolution of 3.5 km, said ISRO.
The image also gives a rather good approximation of what MOM’s color camera will actually see from apoapsis after reaching the Red Planet since the probe will enter a similarly highly elliptical orbit around Mars – ranging in altitude from 366 kilometers (km) x 80,000 kilometers (km).

Following a 10 month interplanetary cruise, MOM is due to arrive in the vicinity of Mars on September 24, 2014 to study the Red Planets’ atmosphere.
At that time, the 440 Newton liquid fueled main engine must fire precisely as planned during the absolutely essential Mars orbital insertion burn to place the probe into orbit about Mars.
But before MOM can accomplish anything at Mars, she must first successfully fire her main engine – to complete the crucial departure from Earth and Trans Mars Insertion (TMI) scheduled for this Saturday!
MOM’s picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from the ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, precisely injected the spacecraft into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.
Since then the engine has fired 6 times to gradually raise the spacecrafts apogee.
The most recent orbit raising maneuver occurred at 01:27 hrs (IST) on Nov 16, 2013 with a burn time of 243.5 seconds increased the apogee from 118,642 km to 192,874 km.
The nail-biting final main engine burn of 1351 seconds is set for this weekend on Dec. 1. It will place MOM on a precise interplanetary trajectory to the Red Planet.

If all continues to goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).
The low cost $69 Million MOM mission is the first of two new Mars orbiter science probes from Earth that flawlessly blasted off for the Red Planet this November.
Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.
The MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist Prof. Bruce Jakosky told Universe Today.

CAPE CANAVERAL, FL – A new space era potentially dawns today, Nov. 25, with the planned maiden launch of the next generation SpaceX Falcon 9 commercial rocket from Cape Canaveral, FL, that could completely revolutionize how we access the high frontier and “rock the space industry to its core” by cutting cost and production times – if all goes well.
Just a day before liftoff, SpaceX founder and CEO Elon Musk personally briefed reporters including Universe Today on Sunday (Nov. 24) in Cocoa Beach, FL, nearby the firms Cape Canaveral launch facility about today’s (Nov. 25) upcoming maiden launch of the companies upgraded Falcon 9 rocket, saying it was “very important” for the future.
“This launch is very important to the future of SpaceX. This is our toughest mission yet!” said Musk to a small group of reporters, including the author, gathered for Sunday’s exclusive pre-launch briefing.
“Whether or not this launch is successful, I’m confident we will certainly make it on some subsequent launch,” said Musk at the Cocoa Beach meeting with the media.
The Falcon 9 liftoff from Launch Complex 40 at Cape Canaveral, FL is scheduled for 5:37pm EST and will be webcast live by SpaceX for viewing at; www.spacex.com/webcast
Today’s (Nov. 25) inaugural blastoff of the privately developed Falcon 9 rocket with the commercial SES-8 HDTV and telecommunications satellite is especially noteworthy because it also features SpaceX’s first ever launch of any satellite to a Geostationary Transfer Orbit (GTO).
From the start, SpaceX designed the Falcon 9 rocket from a clean sheet aimed at radically reducing production and manufacturing costs and assembly times and thereby offer significantly lower launch price, says Musk.
“I don’t want to tempt fate, but I think it’s going to have a pretty significant impact on the world launch market and on the launch industry because our prices are the most competitive of any in the world,” Musk stated.

SES-8 also represents SpaceX’s first launch of a Falcon 9 carrying a commercial satellite to space from the Florida Space Coast.
“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer, who joined Musk at Sunday’s meeting.
The 3,138 kg (6,918 lbs) SES-8 satellite is a hybrid Ku- and Ka-band spacecraft that will provide TV and communications coverage for the South Asia and Asia Pacific regions.

The SES-8 spacecrft was built by Orbital Sciences Corp and will be lofted to a 295 x 80,000 km geosynchronous transfer orbit inclined 20.75 degrees.
SpaceX has signed nearly 50 commercial and government launch contracts and thus already sports a very crowded launch manifest ahead of today’s Falcon 9 launch.
All five launches of SpaceX’s Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station were either test launches or flights to the International Space Station, under contract to NASA.
The five Falcon 9 launches to date from the Florida Space Coast also featured the original, less powerful and shorter version of the booster and has a 100% success rate.
This mighty new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level that rises to 1.5 million pounds as the rocket climbs to orbit.

Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.
The next generation Falcon 9 is a monster. It measures 224 feet tall and is 12 feet in diameter. That compares to 13 stories for the original Falcon 9.
The payload fairing for SES-8 is 17 feet in diameter.
The Falcon 9/SES-8 launch window extends for 66 minutes until 6:43 p.m. EST.
Weather outlook is 80% favorable at this time.
SpaceX is planning a live webcast of the launch with commentary from SpaceX corporate headquarters in Hawthorne, CA.
The broadcast will begin at approximately 5:00 p.m. EDT and include detailed discussions about the Falcon 9 rocket, launch and flight sequences as well as about the SES-8 satellite.

An erupting undersea volcano forms a new island off the coast of Nishinoshima, a small unihabited island in the southern Ogasawara chain of islands. The image was taken on November 21, 2013 by the Japanese Coast Guard.
A volcanic eruption is creating a tiny new island off the coast of Japan. The Japanese Coast Guard snapped images and video of the eruption taking place, showing the new island being formed. Footage showed heavy smoke, ash and rocks spewing from the volcanic crater. As of this writing, experts say the small island is about 200 meters (660 feet) in diameter. It is located just off the coast of Nishinoshima, a small, uninhabited island in the Ogasawara chain, also known as the Bonin Islands, about about 620 miles (1,000 km) south of Tokyo.
See a video and additional images below.
Only time will tell if the island will remain or if the ocean waters will reclaim it. According to Yahoo News, Japan’s chief government spokesman said they would welcome any new territory.
“This has happened before and in some cases the islands disappeared,” Yoshihide Suga said when asked if the government was planning on naming the new island. “If it becomes a full-fledged island, we would be happy to have more territory.”

According to the Smithsonian Global Volcanism Program website, the Japan, Taiwan, Marianas Region is a very active region in the Pacific Ring of Fire and most volcanoes in this region “result from subduction of westward-moving oceanic crust under the Asian Plate. In the Izu-Mariana chain, however, the crust to the west is also oceanic, forming more basaltic island arcs (but with volcanoes that are far more explosive than oceanic hotspot volcanoes).”

A Canadian camera system aiming to provide near-realtime video views of Earth is readying for a launch from Kazakhstan.
If all goes well, the UrtheCast dual camera system will blast off in a Progress supply ship on Nov. 25, 2013.
This will be the world’s first ever high definition, live-streaming video platform of planet Earth from the International Space Station.
“Imagine you have a nearly live Google Earth, but it isn’t four year old data – you have data that is being refreshed all the time, with videos coming down over interesting areas where interesting events are going on, showing you what is changing, what is going on,” said George Tyc, the Chief Technology Officer at UrtheCast, in an interview with Universe Today earlier this year. “What we really hope to pull off is to change the paradigm, get the everyday person interacting and seeing the data coming down from space to see the Earth and how it is evolving over time in a way that isn’t available right now.”
Last week at the Canadian Space Society Summit, UrtheCast co-founder Wade Larson explained the camera setup will take place in phases, with Phase 1 of the project having two cameras facing the ground, with one having a fixed gaze and the other one featuring maneuverability to points of interest. These should be installed on the station sometime in December 2013, Larson said, with data coming in the first quarter of 2014.
The company’s aim is to make Earth video data more accessible to individuals and schoolchildren, who would log in on UrtheCast’s website, as well as the traditional customers of government and private companies. Additionally, a recent partnership agreement with the UN will see them offer real-time information on dynamic situations such as floods and mass movements of people during humanitarian disasters. They will also be integrating the data with live social media feeds as well as opening up their API for app developers.

Current sponsors on the project from UrtheCast (pronunced “Earthcast”) include Roscosmos, MacDonald, Dettwiler and Associates, the Discovery Channel, Energia, Unosat and RAL Space, Larson added.
The UrtheCast team is working in an exclusive relationship with the Russian Aerospace giant RSC Energia (NASA is not involved at all), and cosmonauts on board the ISS will install the cameras. The video data of the Earth will be down-linked to ground stations around the planet and then displayed in near real time on the UrtheCast web platform.
“We had to meet quite a strict set of requirements that the cameras are safe for cosmonauts and astronauts,” Tyc said, “as there can’t be any toxic substances because they will be inside the ISS before they are installed.”
Tyc added that it will take two spacewalks to do the full installation. The cameras are expected to last at least five years, and Tyc expects them to be up there even longer. “We’re looking at putting additional cameras up there for a second generation, and we expect to be up there for the life of the station, really,” he said.
Tyc said he thinks the social media aspect of UrtheCast will be a big part of the entire experience.
“For example, in a natural disaster or big event we’ll also incorporate videos from the ground of things going on, to experience an event in a far different way than you can now,” he said. “And it’s not being filtered through a media agency — it is what it is – and people can draw their own conclusions and add their own voice.”
Tyc said that if the concept takes off, they think this will be a shift in how people can interact with others around the world. “It could be a feeling of the Overview effect – people who go to space are have a completely changed perspective – we’re trying to bring a little bit of that to the ground,” he said.
The team said the name UrtheCast is a bit of a double entendre, as it is pronounced like “EarthCast” but also looks like “You Are the Cast” since it will be live views of planet Earth.

Did you know you can sometimes see Earth’s shadow right here on Earth? This beautiful panorama by John Chumack is a perfect example of this phenomenon, known as the “Belt of Venus.” This beautiful pinkish glow is caused by the backscattering of sunlight and is sometimes referred to as the anti-twilight arch. What you are seeing is the shadow of the Earth’s translucent atmosphere, casting a shadow back upon itself.
“So yes, you can see part of the Earth’s shadow other than during a lunar eclipse,” said John, via email. “I shot this from Indian Lake, Ohio a favorite fishing spot! It is a panorama made from 5 separate shots to show the entire belt of Venus, and the Earth’s shadow (dark area) arching above the horizon.”
John used a simple point and shoot Canon SX 160 IS, hand held for all 5 shots with 30% overlap for the panorama, so no tripod, which is pretty impressive!
“I was fishing and Venus’s Belt was the only thing I caught that evening!” said John.
“MOM is in normal health,” at this time according to the Indian Space Research Organization (ISRO) – which has now scheduled a supplementary main engine firing for early Tuesday (Nov. 12) to boost the crafts orbit the missing 20,000 km required.
Monday’s engine firing only raised MOM’s apogee (farthest point to Earth) from 71,623 km to 78,276 km compared to the originally planned apogee of about 100,000 [1 lakh] km), said ISRO in a press release.
This is the first serious problem to strike MOM in space. And it seemed clear to me something might be amiss when ISRO failed to quickly announce a successful completion of the 4th firing as had been the pattern for the initial three burns.

The premature shutdown of the liquid fueled 440 Newton main engine “imparted an incremental velocity of 35 metres/second as against 130 metres/second originally planned,” ISRO stated.
That’s barely a quarter of what was hoped for.
“A supplementary orbit-raising operation is planned tomorrow (November 12, 2013) at 0500 hrs IST to raise the apogee to nearly 1 lakh [100,000] km.”
A series of six absolutely essential firings of the 440 Newton main engine – dubbed “midnight maneuvers” – had been originally scheduled by Indian space engineers.
The purpose of the “midnight maneuvers” is to achieve Earth escape velocity by gradually raising MOM’s apogee over several weeks, and set her on a trans Mars trajectory to the Red Planet, following the spectacular blastoff on Nov. 5 from India’s spaceport.

MOM was due to depart Earth’s orbit on Dec. 1 after accomplishing the 6th of the originally scheduled thruster firings – and begin a 10 month long interplanetary cruise to Mars.
MOM’s picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from the ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, precisely injected the spacecraft into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.
The 1st, 2nd and 3rd thruster firings were spot on and incrementally raised MOM’s apogee from 23556 km to 28814 km, 40186 km and 71,623 km respectively.
The next firing had been slated for Nov. 16.
Here’s how ISRO described the source of the main engine shutdown:
“During the fourth orbit-raising operations held today (November 11, 2013), the redundancies built-in for the propulsion system were exercised, namely, (a) energising the primary and redundant coils of the solenoid flow control valve of 440 Newton Liquid Engine and (b) logic for thrust augmentation by the attitude control thrusters, when needed.
However, when both primary and redundant coils were energised together, as one of the planned modes, the flow to the Liquid Engine stopped. The thrust level augmentation logic, as expected, came in and the operation continued using the attitude control thrusters. This sequence resulted in reduction of the incremental velocity.”

It is not known at this time how or whether the requirement for a supplemental “midnight maneuver” engine firing will affect the mission’s timing at Earth and its operations and longevity at Mars.
Why are the firings called midnight maneuvers?
“Firing has to happen near the perigee and in the visibility from ISTRAC ground stations. All these orbits have argument of perigee of ~285 deg. When all these constraints are put together, firings time will almost always fall in to midnights of Indian sub continent,” said ISRO in response to a readers inquiry.
In the latest update, ISRO reports: “After achieving an apogee of around 78,000 km in last night’s Maneuver, ISRO’s Mars Orbiter Mission Spacecraft is all set to reach the apogee of One lakh km in a supplementary maneuver scheduled for 5 AM tomorrow. [Nov 12].”
MOM was to arrive in the vicinity of Mars on September 24, 2014 when the absolutely essential Mars orbital insertion firing by the 440 Newton liquid fueled main engine will slow the probe and place it into a 366 km x 80,000 km elliptical orbit.

The low cost $69 Million MOM mission is the first of two new Mars orbiter science probes from Earth blasting off for the Red Planet this November.
Half a world away, NASA’s $671 Million MAVEN orbiter remains on target to launch in less than one week on Nov. 18 – from Cape Canaveral, Florida.

NASA GODDARD SPACE FLIGHT CENTER, MARYLAND – Super Typhoon Haiyan smashed into the island nation of the Philippines, Friday, Nov. 8, with maximum sustained winds estimated at exceeding 195 MPH (315 kilometer per hour) by the U.S. Navy Joint Typhoon Warning Center – leaving an enormous region of catastrophic death and destruction in its terrible wake.
The Red Cross estimates over 1200 deaths so far. The final toll could be significantly higher. Local media reports today say bodies of men, women and children are now washing on shore.
The enormous scale of Super Typhoon Haiyan can be vividly seen in space imagery captured by NASA, ISRO and Russian satellites – as well as astronaut Karen Nyberg flying overhead on board the International Space Station (ISS); collected here.

Super Typhoon Haiyan is reported to be the largest and most powerful storm ever to make landfall in recorded human history.
Haiyan is classified as a Category 5 monster storm on the U.S. Saffir-Simpson scale.
It struck the central Philippines municipality of Guiuan at the southern tip of the province of Eastern Samar early Friday morning Nov. 8 at 20:45 UTC (4:45 am local time).
As Haiyan hit the central Philippines, NASA says wind gusts exceeded 235 mph (379 kilometers per hour).
The high resolution imagery and precise measurements provided by the worlds constellation of Earth observing space satellites (including NASA, Roscosmos, ISRO, ESA, JAXA) are absolutely essential to tracking killer storms and providing significant advance warning to evacuate residents in affected areas to help minimize the death toll and damage.
More than 800,000 people were evacuated. The storm surge caused waves exceeding 30 feet (10 meters), mudslides and flash flooding.
NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite captured visible, microwave and infrared data on the storm just as it was crossing the island of Leyte in the central Philippines, reports NASA – see image below.
NASA’s TRMM satellite data on Nov. 8 at 00:19 UTC showed Haiyan had a well-defined eye surrounded by a symmetric area of moderate rain (green ring with a blue center) with several rainbands wrapping in from the south (green arcs) while crossing the island of Leyte in the central Philippines.

TRMM data from rain rates are measured by the TRMM Precipitation Radar (PR) and TRMM Microwave Imager (TMI) and combined with infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS) by science teams working at NASA’s Goddard Space Flight Center in Greenbelt, Md.
Coincidentally NASA Goddard has just completed assembly of the next generation weather satellite Global Precipitation Measurement (GPM) observatory that replaces TRMM – and where I inspected the GPM satellite inside the Goddard clean room on Friday.
“GPM is a direct follow-up to NASA’s currently orbiting TRMM satellite,” Art Azarbarzin, GPM project manager, told Universe Today during my exclusive clean room inspection of the huge GPM satellite.

“TRMM is reaching the end of its usable lifetime. GPM launches in February 2014 and we hope it has some overlap with observations from TRMM.”
“The Global Precipitation Measurement (GPM) observatory will provide high resolution global measurements of rain and snow every 3 hours,” Dalia Kirschbaum, GPM research scientist, told me at Goddard.
GPM is equipped with advanced, higher resolution radar instruments. It is vital to continuing the TRMM measurements and will help provide improved forecasts and advance warning of extreme super storms like Hurricane Sandy and Super Typhoon Haiyan, Azarbarzin and Kirschbaum explained.

Antarctica's sea ice on Sept. 22, 2013. Scientists say there was more ice on the ocean then than in any time in recorded satellite history. Data came from the Advanced Microwave Scanning Radiometer 2 (AMSR2) sensor on Japan’s Global Change Observation Mission 1st-Water (GCOM-W1) satellite. You can see the land in dark gray and ice shelves in light gray. The yellow line represents the average distribution of sea ice between 1981 and 2000.

Antarctica’s sea ice is creeping further out in the ocean! New data from a Japanese satellite shows that sea ice surrounding the southern continent in late September reached out over 7.51 million square miles (19.47 million square kilometers).
The extent — a slight increase over 2012’s record of 7.50 million square miles (19.44 million square km) — is the largest recorded instance of Antarctica sea ice since satellite records began, NASA said. Data was recorded using the Advanced Microwave Scanning Radiometer 2 (AMSR2) sensor on the Global Change Observation Mission 1st-Water (GCOM-W1) satellite.
“While researchers continue to study the forces driving the growth in sea ice extent, it is well understood that multiple factors—including the geography of Antarctica, the region’s winds, as well as air and ocean temperatures—all affect the ice,” NASA stated.
Update — see below for a more detailed description of why this is an important clue that climate change IS happening.
“Geography and winds are thought to be especially important. Unlike the Arctic, where sea ice is confined in a basin, Antarctica is a continent surrounded by open ocean. Since its sea ice is unconfined, it is particularly sensitive to changes in the winds. As noted by the National Snow and Ice Data Center, some research has suggested that changes in Antarctic sea ice are caused in part by a strengthening of the westerly winds that flow unhindered in a circle above the Southern Ocean.”
For those thinking that increased sea ice means we can relax about climate change, this humorous video explains the difference between land ice (glaciers) and sea ice (which is generated from snow, rainfall and fresh water). It’s definitely worth four minutes of your time. The part about sea ice starts around 2:45.
UPDATE: Just to clarify:
Here’s what the graphic says: “The water around Antarctica is more fresh than it has been in previous years because of increased snow and rainfall as well as in increased contribution of fresh water from melting land ice. This fresh cold water is less dense than the warmer, saltier water below. Previously, that warm salty water would rise, melting the sea ice. But now, bcaus of the lighter fresh water on top, there is less mixing of the ocean’s layer and the surface stays cooler longer. “
And so, there is increased fresh water because of the melting land ice – due to climate change. There is a fundamental difference between sea ice and land ice. Antarctic land ice is the ice which has accumulated over thousands of years on the Antarctica landmass through snowfall. Antarctic sea ice is entirely different as it is ice which forms in salt water during the winter and almost entirely melts again in the summer.
Importantly, when land ice melts and flows into the oceans global sea levels rise on average; when sea ice melts sea levels do not change measurably but other parts of the climate system are affected, like increased absorption of solar energy by the darker oceans.
We’ve talked about Venus, the hottest planet in the Solar System, but we know things can get pretty hot here on Earth, too. You may be wondering, where on the surface of the Earth has the highest natural temperature been recorded?
The location of this world record has had some controversy, but as of 2013, the hottest spot on record was the Furnace Creek Ranch in California’s Death Valley. On July 10, 1913, weather instruments measured 56.7 degrees Celsius, or 134 degrees Fahrenheit.
The previous record of 56 degrees at El Azizia, Libya was overturned because a systematic study in 2012 discovered there were errors in the measuring methods.
Similar temperatures to Death Valley’s record have been recorded around the World:
55 degrees in Africa,
53.6 in Asia,
50.7 in Australia,
and 49.1 in Argentina.
But these are just measurements from weather stations. It’s likely there are hotter temperatures, but nobody was around to measure. NASA satellites have spotted regions in Iran’s Lut desert which might have reached 70 degrees Celsius during the summers of 2004 and 2005.
So that’d be the hottest spot on the surface, but what about the hottest natural spot anywhere in the entire planet? Now you’ve got to travel straight down 6,371 kilometers to the very center of the Earth. At the inner core, the temperatures rise to about 5,430 degrees C, or 5700 Kelvin. Amazingly, this is about the same temperature as the surface of the Sun.
Some of this high temperature comes from leftover heat from the formation of the planet, 4.54 billion years ago, but the vast majority comes from the decay of radioactive minerals inside the Earth. It was likely hotter in the past, but all the short-period isotopes have already been depleted.
I keep saying the word “natural”, but what about “unnatural”? Wondering about the hottest temperature EVER generated on Earth? Thermonuclear explosions reach temperatures of tens of millions of Kelvin. Fusion experiments have hit 500 million Kelvin. But that’s nothing.
In 2012, physicists working with the Large Hadron Collider were investigating the conditions that might have existed during the earliest moments of the Big Bang.
They generated a quark gluon plasma that had a temperature of 5.5 trillion Kelvin.
Unless aliens can do better, this is not only the hottest temperature ever recorded on Earth, it’s easily the hottest temperature anywhere in the Universe since the Big Bang itself.
