KENNEDY SPACE CENTER, FL – NASA’s first ever ‘Year in Space’ astronaut Scott Kelly was in good shape and smiling broadly for the Earth bound photographers after safely returning to Earth from his orbiting home of the past year on the International Space Station (ISS), for a smooth touchdown in the steppes of Kazakhstan late Monday evening, March 1.
He soon jetted back to the USA for a grand arrival ceremony back home in Houston in the wee hours of the morning, today, March 3, 2016.
“Great to be back on Earth, said Kelly. “There’s no place like home!”
Kelly landed on US soil at Houston’s Ellington Field early this morning at about 2:30 a.m.
Kelly was welcomed back to the USA by Second Lady of the United States Dr. Jill Biden, Assistant to the President for Science and Technology Dr. John P. Holdren, NASA Administrator and former astronaut Charles Bolden, and Kelly’s identical twin brother and former NASA astronaut Mark Kelly.
Before departing the station after a 340 day stay, Kelly said that among the things he missed most on Earth were fresh air and food and freedom of movement. And swimming in his pool.
Well he quickly made good on those wishes and after arriving back home before daylight soon took a dip in his backyard pool.
Kelly posted a video of his pleasant pool plummet in all its glory on twitter: Tweets by StationCDRKelly
“Man, that feels good!” he exclaimed.

The long trip back home began after Kelly boarded his Russian Soyuz TMA-18M return capsule along with Russian cosmonaut crewmates Mikhail Kornienko and Sergey Volkov.
Kelly and his Russian cohort Mikhail Kornienko comprised the first ever crew to live and work aboard the ISS for a record breaking year-long mission aimed at taking concrete steps towards eventually dispatching human crews for multiyear-long expeditions to the surface of Mars and back.
Volkov spent a normal six month increment aboard the station.

The goal of the 1 year ISS mission was to collect a variety of data on the effects of long duration weightlessness on the human body that will be used to formulate a human mission to Mars.
Kelly and Kornienko originally launched to the station on March 27, 2015 along with Russian crewmate Gennady Padalka.
The trio undocked from the station inside their cramped Soyuz capsule, pulled away, fired breaking thrusters and plummeted back to Earth a few hours later, surviving scorching reentry temperatures as the passed through the Earth atmosphere.
They safely landed in Kazakhstan at 11:26 p.m. EST on Tuesday night, March 1, 2016 (10:26 a.m. March 2 Kazakhstan time), concluding Expedition 46.

Kelly set an American record for longest time in space on a single mission by living and working for 340 days straight aboard the ISS.
Kelly and Kornienko share the history making distinction of comprising the first ever ‘1 Year Crew’ to serve aboard the massive Earth orbiting science research outpost in space.
With a cumulative total of 520 days in space, Kelly has amassed the most time for an American in space. Kornienko has accumulated 516 days across two flights, and Volkov has 548 days on three flights.
During the yearlong mission 10 astronauts and cosmonauts representing six different nations including the United States, Russia, Japan, Denmark, Kazakhstan and England lived aboard the space station.
The station currently remains occupied by a three person crew hailing from the US, Russia and England. A new three person crew launches later in March.
NASA’s next commercial resupply launch to the station is slated for March 22 by a United Launch Alliance Atlas V rocket carrying an Orbital ATK Cygnus cargo freighter with over 7000 pounds of fresh science experiments and crew supplies.

“What happened to Mars?” is one of the most compelling questions in space science. It probably wasn’t always the dead, dry, cold place it is now. Did its core cool and stop rotating, allowing the full glare of the sun to blast away its atmosphere and water, and kill anything that may have lived there? Was it struck by a large body, which incinerated its atmosphere, and led to its demise? Were there other causes?
According to a new research paper from Sylvain Bouley at the University of Paris-South, and his colleagues, it may have been a massive, ancient outpouring of molten rock that threw Mars off kilter and helped change Mars into what it is today.
The Tharsis region is an ancient lava complex on Mars that dates back to between 4.1 billion and 3.7 billion years ago. It’s located in Mars’ Western Hemisphere, right near the equator. It’s made up of three huge shield volcanoes—Arsia Mons, Pavonis Mons, and Ascraeus Mons. Collectively, they’re known as Tharsis Montes. (Olympus Mons, the largest volcano in the Solar System, is not a part of the Tharsis complex, though it is near it.)
Tharsis is over 5,000 km across and over 10 miles thick, making it the largest volcanic complex in the Solar System. That much mass positioned after Mars was already formed and had an established rotation would have been cataclysmic. Think what would happen to Earth if Australia rose up 10 miles.

The new paper, published on March 2nd, 2016, in the journal Nature, says that the position of the Tharsis complex would have initiated a True Polar Wander (TPW.) Basically, what this means is that Tharsis’ huge mass would have forced Mars to shift its rotation, so that the location of Tharsis became the new equator.
It was thought that the emergence of Tharsis made Martian rivers—which formed later—flow the direction they do. But the study from Bouley and his colleagues shows that Martian rivers and valleys formed first—or maybe concurrently—and that the Tharsis TPW deformed the planet later.
The authors of the study calculated where the Martian poles would have been prior to Tharsis, and looked for evidence of polar conditions at those locations. The location of this ancient north pole contains a lot of ice today, and the location of the ancient south polar region also shows evidence of water.
What it all adds up to is that the disappearance of water on Mars probably happened at the same time as the TPW. Whether the appearance of the Tharsis lava complex, and the resulting cataclysmic shifting of Mars’ rotational orientation, were the cause of Mars losing its climate is not yet known for sure. But this study shows that the ancient volcanic cataclysm did at least help shape Mars into what it is today.

The Obama Administration has announced its new Federal budget and is proposing to cut NASA’s Fiscal Year 2017 Budget to $19 billion by carving away significant funding for deep space exploration, whereas the overall US Federal budget actually increases to over $4.1 trillion.
This 2017 budget request amounts to almost $300 million less than the recently enacted NASA budget for 2016 and specifically stipulates deep funding cuts for deep space exploration programs involving both humans and robots, during President Obama’s final year in office.
The 2017 budget proposal would slash funding to the very programs designed to expand the frontiers of human knowledge and aimed at propelling humans outward to the Red Planet and robots to a Jovian moon that might be conducive to the formation of life.
Absent sufficient and reliable funding to keep NASA’s exploration endeavors on track, further launch delays are almost certainly inevitable – thereby fraying American leadership in space and science.
The administration is specifying big funding cuts to the ongoing development of NASA’s mammoth Space Launch System (SLS) heavy lift rocket and the state of the art Orion deep space crew capsule. They are the essential first ingredients to carry out NASA’s ambitious plans to send astronauts on deep space ‘Journey to Mars’ expeditions during the 2030s.
The overall Exploration Systems Development account for human deep space missions would be slashed about 18 percent from the 2016 funding level; from $4.0 Billion to only $3.3 Billion, or nearly $700 million.
SLS alone is reduced the most by $700 million from $2.0 billion to $1,31 billion, or a whopping 35 percent loss. Orion is reduced from $1.27 billion to $1.12 billion for a loss of some $150 million.
Make no mistake. These programs are already starved for funding and the Obama administration tried to force similar cuts to these programs in 2016, until Congress intervened.
Likewise, the Obama administration is proposing a draconian cut to the proposed robotic mission to Jupiter’s moon Europa that would surely delay the launch by at least another half a decade or more – to the late 2020s.
The Europa mission budget proposal is cut to only $49 million and the launch is postponed until the late 2020s. The mission received $175 million in funding in 2016 – amounting to a 72 percent reduction.
Furthermore there is no funding for a proposed lander and the launch vehicle changes from SLS to a far less powerful EELV – causing a year’s long increased travel time.
In order to maintain an SLS launch in approximately 2022, NASA would require a budget of about $150 million in 2017, said David Radzanowski, NASA’s chief financial officer, during a Feb. 9 teleconference with reporters.
Why is Europa worth exploring? Because Europa likely possesses a subsurface ocean of water and is a prime target in the search for life!
Overall, NASA’s hugely successful Planetary Sciences division suffers a huge and nearly 10 percent cut of $141 million to $1.51 billion – despite undeniably groundbreaking scientific successes this past year at Pluto, Ceres, Mars and more!
Altogether NASA would receive $19.025 billion in FY 2017. This totals $260 million less than the $19.285 billion appropriated in FY 2016, and thus corresponds to a reduction of 1.5 percent.
By contrast, the overall US Federal Budget will increase nearly 5 percent to approximately $4.1 trillion. Simple math demonstrates that NASA is clearly not a high priority for the administration. NASA’s share of the Federal budget comes in at less than half a cent on the dollar.

NASA’s Fiscal Year 2017 budget proposal was announced by NASA Administrator Charles Bolden during a televised ‘State of NASA’ address at the agency’s Langley Research Center in Virginia on Feb. 9.
Bolden did not dwell at all on the significant funding reductions for exploration.
“We are hitting our benchmarks with new exploration systems like the Space Launch System rocket and the Orion Crew Vehicle. A new consensus is emerging in the scientific and policy communities around our vision, timetable and plan for sending American astronauts to Mars in the 2030s.”
And he outlined some milestones ahead.
“We’ll continue to make great progress on the Space Launch System – SLS–rocket and we’re preparing for a second series of engine tests,” said Bolden.
“At the Kennedy Space Center, our teams will outfit Orion’s crew module with the spacecraft’s heat-shielding thermal protection systems, avionics and subsystems like electrical power storage, cabin pressure control and flight software –to name just a few.”

The launch date for the first crewed flight on EM-2 was targeted for 2021. But EM-2 is likely to slip to the right to 2023, due to insufficient funding.
Lack of funding will also force NASA to delay development of the far more capable and powerful Exploration Upper Stage (EUS) to propel Orion on deep space missions. It will now not be available for the SLS/EM-2 launch as hoped.
The proposed huge budget cuts to SLS, Orion and Europa are certain to arose the ire of multiple members of Congress and space interest groups, who just successfully fought to increase NASA’s FY 2016 budget for these same programs in the recently passed 2016 omnibus spending bill.
“This administration cannot continue to tout plans to send astronauts to Mars while strangling the programs that will take us there,” said Rep. Lamar Smith (R-Texas), Chairman of the House Science, Space, and Technology Committee, in a statement in response to the president’s budget proposal.
“President Obama’s FY17 budget proposal shrinks our deep space exploration programs by more than $800 million. And the administration once more proposes cuts of more than $100 million to the Planetary Science accounts, which have previously funded missions like this past year’s Pluto flyby.”
“This imbalanced proposal continues to tie our astronauts’ feet to the ground and makes a Mars mission all but impossible. This is not the proposal of an administration that is serious about maintaining America’s leadership in space.”

“The Coalition for Deep Space Exploration … had hoped the request would reflect the priorities laid out for NASA in the FY16 Omnibus, for which there was broad support,” said Mary Lynne Dittmar, executive director of the Coalition for Deep Space Exploration, in a statement.
“Unfortunately this was not the case. The Coalition is disappointed with the proposed reduction in funding below the FY16 Omnibus for NASA’s exploration programs. We are deeply concerned about the Administration’s proposed cut to NASA’s human exploration development programs.”
“This proposed budget falls well short of the investment needed to support NASA’s exploration missions, and would have detrimental impacts on cornerstone, game-changing programs such as the super-heavy lift rocket, the Space Launch System (SLS), and the Orion spacecraft – the first spacecraft designed to reach multiple destinations in the human exploration of deep space.”

On Dec. 18, 2015, the US Congress passed and the president signed the 2016 omnibus spending bill which funds the US government through the remainder of the 2016 Fiscal Year.
As part of the omnibus bill, NASA’s approved budget amounted to nearly $19.3 Billion. That was an outstanding result and a remarkable turnaround to some long awaited good news from the decidedly negative outlook earlier in 2015.
The 2016 budget represented an increase of some $750 million above the Obama Administration’s proposed NASA budget allocation of $18.5 Billion for Fiscal Year 2016, and an increase of more than $1.2 Billion over the enacted budget for FY 2015.
And the hunt for extraterrestrial life on the icy moons of the outer solar system is postponed yet again.

One of the greatest things about being a space enthusiast is all of the discoveries that come out on an almost daily basis. One of the saddest things about being a space enthusiast is all of the discoveries and destinations that are so close, just beyond the horizon of our lifespan.
Will we colonize other planets? Sure, but most of us living will be gone by then. Will we spend time in glorious, gleaming space habitats? Obviously, but we’ll just be epitaphs by then. Sentient, alien species that gift us faster-than-light travel and other wonders? Maybe, but not before my bucket list has its final item checked off.
Citizen space travel? Hmmmm, tantalizingly within reach.
But now, new retro style posters from NASA, designed by the team at Invisible Creature, are making us feel nostalgic about things that haven’t even happened yet, and are helping us leave behind gloomy thoughts of being born at the wrong time.
The Grand Tour. Image: NASA/JPL
The Grand Tour celebrates a time when our probes toured the planets, using gravity assist to propel them on their missions.
“Grandpa, do you remember the Grand Tour, when spacecraft used gravity assist to visit other worlds?”
“I sure do. Gravity assist. Those were the days. Swooping so close to Jupiter, you could feel the radiation killing your hair follicles. Only to be sling-shotted on to the next planet.”
“But why didn’t you just use a quantum drive to bend space time and appear at your destination?”
“Quantum drives! Those things ain’t natural. And neither is bending space-time. Give me a good old-fashioned chemical rocket any time.”
“Oh Grandpa.”

Visit the Historic Sites of Mars recalls a time when space pioneers colonized and terraformed Mars.
“Grandpa, what was Mars like in the Early Days?”
“You mean before it was terraformed? Very tough times.”
“Because conditions were so difficult? And food was hard to grow?”
“No. Because of the protesters.”
“Protesters? On Mars?”
“Yup. Every time we found a good spot for a Bacterial Production Facility (BPF), it seemed like there was an expired old rover in the way. The protesters didn’t think we should move ’em. Part of our heritage.”
“So what did you do Grandpa?”
“We created a network of computers that everybody would stare at all day. After that, nobody noticed what we did anymore.”

Elon Musk has always been up-front about his desire to see humans settle on the Red Planet. In the past few years, he has said that one of his main reasons for establishing SpaceX was to see humanity colonize Mars. He has also stated that he believes that using Mars as a “backup location” for humanity might be necessary for our survival, and even suggested we use nukes to terraform it.
And in his latest speech extolling the virtues of colonizing Mars, Musk listed another reason. The Hyperloop – his concept for a high-speed train that relies steel tubes, aluminum cars and maglev technology to go really fast – might actually work better in a Martian environment. The announcement came as part of the award ceremony for the Hyperloop Pod Competition, which saw 100 university teams compete to create a design for a Hyperloop podcar.
It was the first time that Musk has addressed the issue of transportation on Mars. In the past, he has spoken about establishing a colony with 80,000 people, and has also discussed his plans to build a Mars Colonial Transporter to transport 100 metric tons (220,462 lbs) of cargo or 100 people to the surface of Mars at a time (for a fee of $50,000 apiece). He has also discussed communications, saying that he would like to bring the internet to Mars once a colony was established.

But in addressing transportation, Musk was able to incorporate another important concept that he has come up with, and which is also currently in development. Here on Earth, the Hyperloop would rely on low-pressure steel tubes and a series of aluminum pod cars to whisk passengers between major cities at speeds of up to 1280 km/h (800 mph). But on Mars, according to Musk, you wouldn’t even need tubes.
As Musk said during the course of the ceremony: “On Mars you basically just need a track. You might be able to just have a road, honestly. [It would] go pretty fast… It would obviously have to be electric because there’s no oxygen. You have to have really fast electric cars or trains or things.”
Essentially, Musk was referring to the fact that since Mars has only 1% the air pressure of Earth, air resistance would not be a factor. Whereas his high-speed train concept requires tubes with very low air pressure to reach the speed of sound here on Earth, on Mars they could reach those speeds out in the open. One might say, it actually makes more sense to build this train on Mars rather than on Earth!
The Hyperloop Pod Competition, which was hosted by SpaceX, took place between Jan 27th and 29th. The winning entry came from MIT, who’s design was selected from 100 different entries. Their pod car, which is roughly 2.5 meters long and 1 meter wide (8.2 by 3.2 feet), would weight 250 kg (551 lbs) and be able to achieve an estimated cruise speed of 110 m/s (396 km/h; 246 mph). While this is slightly less than a third of the speed called for in Musk’s original proposal, this figure representing cruising speed (not maximum speed), and is certainly a step in that direction.

And while Musk’s original idea proposed that the pod be lifted off the ground using air bearings, the MIT team’s design called for the use of electrodynamic suspension to keep itself off the ground. The reason for this, they claimed, is because it is “massively simpler and more scalable.” In addition, compared to the other designs’ levitation systems, theirs had one of the lowest drag coefficients.
The team – which consists of 25 students with backgrounds in aeronautics, mechanical engineering, electrical engineering, and business management – will spend the next five months building and testing their pod. The final prototype will participate in a trial run this June, where it will run on the one-mile Hyperloop Test Track at SpaceX’s headquarters in California.
Since he first unveiled it back in 2013, Musk’s Hyperloop concept has been the subject of considerable interest and skepticism. However, in the past few years, two companies – Hyperloop Transportation Technologies (HTT) and Hyperloop Technologies – have emerged with the intention of seeing the concept through to fruition. Both of these companies have secured lucrative partnerships since their inception, and are even breaking ground on their own test tracks in California and Nevada.
And with a design for a podcar now secured, and tests schedules to take place this summer, the dream of a “fifth mode of transportation” is one step closer to becoming a reality! The only question is, which will come first – Hyperloops connecting major cities here on Earth, or running passengers and freight between domed settlements on Mars?
Only time will tell! And be sure to check out Team MIT’s video:

Evidence of water and a warmer, wetter climate abound on Mars, but did life ever put its stamp on the Red Planet? Rocks may hold the secret. Knobby protuberances of rock discovered by the Spirit Rover in 2008 near the rock outcrop Home Plate in Gusev Crater caught the attention of scientists back on Earth. They look like cauliflower or coral, but were these strange Martian rocks sculpted by microbes, wind or some other process?

When analyzed by Spirit’s mini-TES (Mini-Thermal Emission Spectrometer), they proved to be made of nearly pure silica (SiO2), a mineral that forms in hot, volcanic environments. Rainwater and snow seep into cracks in the ground and come in contact with rocks heated by magma from below. Heated to hundreds of degrees, the water becomes buoyant and rises back toward the surface, dissolving silica and other minerals along the way before depositing them around a vent or fumarole. Here on Earth, silica precipitated from water leaves a pale border around many Yellowstone National Park’s hot springs.

Both at Yellowstone, the Taupo Volcanic Zonein New Zealand and in Iceland, heat-loving bacteria are intimately involved in creating curious bulbous and branching shapes in silica formations that strongly resemble the Martian cauliflower rocks. New research presented at the American Geophysical Union meeting last month by planetary geologist Steven Ruff and geology professor Jack Farmer, both of Arizona State University, explores the possibility that microbes might have been involved in fashioning the Martian rocks, too.
A sizzling visit to El Tatio’s geysers
The researchers ventured to the remote geyser fields of El Tatio in the Chilean Atacama Desert to study an environment that may have mimicked Gusev Crater billions of years ago when it bubbled with hydrothermal activity. One of the driest places on Earth, the Atacama’s average elevation is 13,000 feet (4 km), exposing it to considerably more UV light from the sun and extreme temperatures ranging from -13°F to 113°F (-10° to 45°C). Outside of parts of Antarctica, it’s about as close to Mars as you’ll find on Earth.
Ruff and Farmer studied silica deposits around hot springs and geysers in El Tatio and discovered forms they call “micro-digitate silica structures” similar in appearance and composition to those on Mars (Here’s a photo). The infrared spectra of the two were also a good match. They’re still analyzing the samples to determine if heat-loving microbes may have played a role in their formation, but hypothesize that the features are “micro-stromatolites” much like those found at Yellowstone and Taupo.

Stromatolites form when a sticky film of bacteria traps and cements mineral grains to create a thin layer. Other layers form atop that one until a laminar mound or column results. The most ancient stromatolites on Earth may be about 3.5 billion years old. If Ruff finds evidence of biology in the El Tatio formations in the punishing Atacama Desert environment, it puts us one step closer to considering the possibility that ancient bacteria may have been at work on Mars.
Scientists have found evidence that Home Plate at Gusev crater on Mars is composed of debris deposited from a hydrovolcanic explosion. The finding suggests that water may have been involved in driving an eruption that formed the deposits found on Home Plate. Spirit found the silica-rich rocks at lower right near Tyrone in 2008.

Silica forms may originate with biology or from non-biological processes like wind, water and other environmental factors. Short of going there and collecting samples, there’s no way to be certain if the cauliflower rocks are imprinted with the signature of past Martian life. But at least we know of a promising place to look during a future sample return mission to the Red Planet. Indeed, according to Ruff, the Columbia Hills inside Gusev Crater he short list of potential sites for the 2020 Mars rover.
