Underground lake found on Mars, raising possibility of life

By Will Dunham

WASHINGTON (Reuters) – Using a radar instrument on an orbiting spacecraft, scientists have spotted what they said on Wednesday appears to be a sizable salt-laden lake under ice on the southern polar plain of Mars, a body of water they called a possible habitat for microbial life.

The reservoir they detected — roughly 12 miles (20 km) in diameter, shaped like a rounded triangle and located about a mile (1.5 km) beneath the ice surface — represents the first stable body of liquid water ever found on Mars.

Whether anywhere other than Earth has harbored life is one of the supreme questions in science, and the new findings offer tantalizing evidence, though no proof. Water is considered a fundamental ingredient for life.

The researchers said it could take years to verify whether something is actually living in this body of water that resembles a subglacial lake on Earth, perhaps with a future mission drilling through the ice to sample the water below.

“This is the place on Mars where you have something that most resembles a habitat, a place where life could subsist,” said planetary scientist Roberto Orosei of Istituto Nazionale di Astrofisica in Italy, who led the research published in the journal Science.

“This kind of environment is not exactly your ideal vacation, or a place where fish would swim,” Orosei added. “But there are terrestrial organisms that can survive and thrive, in fact, in similar environments. There are microorganisms on Earth that are capable of surviving even in ice.”

The detection was made using data collected between May 2012 and December 2015 by an instrument aboard the European Space Agency’s Mars Express spacecraft that transmits radar pulses, which penetrate the Martian surface and ice caps.

“This took us long years of data analysis and struggles to find a good method to be sure that what we were observing was unambiguously liquid water,” said study co-author Enrico Flamini, chief scientist at the Italian Space Agency during the research.

The location’s radar profile resembled that of subglacial lakes found beneath Earth’s Antarctic and Greenland ice sheets.

Mars long ago was warmer and wetter, possessing significant bodies of water, as evidenced by dry lake beds and river valleys on its surface. There had been some signs of liquid water currently on Mars, including disputed evidence of water activity on Martian slopes, but not stable bodies of water.

Orosei said the water in the Martian lake was below the normal freezing point but remained liquid thanks in large part to high levels of salts. Orosei estimated the water temperature at somewhere between 14 degrees Fahrenheit (minus 10 degrees Celsius) and minus 94 degrees Fahrenheit (minus 70 degrees Celsius).

It remains to be seen if more subsurface reservoirs of water will be found or whether the newly discovered one is some sort of quirk, Orosei said.

If others are detected and a network of subglacial lakes exists like on Earth, he said, that could indicate liquid water has persisted for millions of years or even dating back to 3-1/2 billion years ago when Mars was a more hospitable planet.

The question would be, Orosei added, whether any life forms that could have evolved long ago on Mars have found a way to survive until now.

“Nobody dares to propose that there could be any more complex life form,” Orosei said.

SpaceX’s Falcon Heavy rocket soars in debut test launch from Florida

A SpaceX Falcon Heavy rocket lifts off from historic launch pad 39-A at the Kennedy Space Center in Cape Canaveral, Florida, U.S., February 6, 2018.

By Joey Roulette

CAPE CANAVERAL, Fla. (Reuters) – The world’s most powerful rocket, SpaceX’s Falcon Heavy, roared into space through clear blue skies on its debut test flight on Tuesday from a Florida launch site in another milestone for billionaire entrepreneur Elon Musk’s private rocket service.

The 23-story-tall jumbo rocket, carrying a cherry red Tesla Roadster from the assembly line of Musk’s electric car company as a mock payload, thundered off its launchpad in billowing clouds of steam and rocket exhaust at 3:45 p.m (2045 GMT) from the Kennedy Space Center in Cape Canaveral, where moon missions once began.

Boisterous cheering could be heard from SpaceX workers at the company’s headquarters in Hawthorne, California, where a livestream feed of the event originated. At least 2,000 spectators cheered the blastoff from a campground near Cocoa Beach, 5 miles (8 km) from the space center.

Within three minutes, the Falcon Heavy’s two side boosters separated from the central rocket in one of the most critical points of the flight.

Then, capitalizing on cost-cutting reusable rocket technology pioneered by SpaceX, the two boosters flew themselves back to Earth for safe simultaneous touchdowns on twin landing pads at Cape Canaveral Air Force Station, about eight minutes after launch. Each rocket unleashed a double sonic boom as it neared the landing zone.

The center booster rocket, which SpaceX had predicted was less likely to be salvaged, slammed into the Atlantic at about 300 miles per hour (483 kph), showering the deck of the nearby drone landing vessel and destroying two of the ship’s thrusters, Musk told a post-launch news conference.

‘CRAZY THINGS COME TRUE’

Still, the Silicon Valley mogul known for self-deprecating understatement hailed the launch as a victory and “a big relief.”

“I had this image of this giant explosion on the pad, with wheels bouncing down the road and the logo landing somewhere with a thud. But fortunately, that’s not what happened,” he said. “Crazy things come true.”

While the Falcon Heavy’s initial performance appeared, by all accounts, to have been near flawless, it remained to be seen whether the upper stage of the vehicle and its payload would survive a six-hour “cruise” phase to high Earth orbit through the planet’s radiation belts.

The launch, so powerful that it shook the walls of the press trailer at the complex, was conducted from the same site used by NASA’s towering Saturn 5 rockets to carry Apollo missions to the moon more than 40 years ago. SpaceX has said it aspires to send missions to Mars in the coming years.

The successful liftoff was a key turning point for Musk’s privately owned Space Exploration Technologies, which stands to gain a new edge over the handful of rivals vying for lucrative contracts with NASA, satellite companies and the U.S. military.

Falcon Heavy is designed to place up to 70 tons into standard low-Earth orbit at a cost of $90 million per launch. That is twice the lift capacity of the biggest existing rocket in America’s space fleet – the Delta 4 Heavy of rival United Launch Alliance (ULA), a partnership of Lockheed Martin Corp and Boeing Co- for about a fourth the cost.

The demonstration flight put the Heavy into the annals of spaceflight as the world’s most powerful rocket in operation, with more lift capacity than any space vehicle to fly since NASA’s Saturn 5, which was retired in 1973, or the Soviet-era Energia, which flew its last mission in 1988.

Propelled by 27 rocket engines, the Heavy packs more than 5 million pounds of thrust at launch, roughly three times the force of the Falcon 9 booster rocket that until now has been the workhorse of the SpaceX fleet. The new rocket is essentially constructed from three Falcon 9s bolted together side by side.

‘NEW SPACE RACE?’

Going along for the ride in a bit of playful cross-promotional space theater was the sleek red, electric-powered sports car from Musk’s other transportation enterprise, Tesla Inc.

Adding to the whimsy, SpaceX planted a space-suited mannequin in the driver’s seat of the convertible Tesla Roadster.

Musk mused that “it may be discovered by some future alien race.” The white spacesuit was real, he said.

A third burn was successful, Musk Tweeted late on Tuesday, sending the Tesla Roadster into its planned trajectory.

“Exceeded Mars orbit and kept going to the Asteroid Belt,” he tweeted.

The roadster, which carries a plaque inscribed with the names of more than 6,000 SpaceX employees, could instead end up in perpetual Earth orbit.

The launch followed an impressive run of successful paid missions – 20 in all since January 2017, when SpaceX returned to flight following a 2016 launchpad accident that destroyed a $62 million rocket and a $200 million Israeli communications satellite that it was to put into orbit two days later.

Musk said he hoped Tuesday’s achievement would encourage a new “space race” by private ventures and other countries, an allusion to the 1960s Cold War contest between the United States and the Soviet Union.

“Space races are exciting,” he said.

SpaceX had previously announced plans to eventually use Falcon Heavy to launch two paying space tourists on a trip around the moon. Musk said on Monday he was now inclined to reserve that mission for an even more powerful SpaceX launch system, the Big Falcon Rocket, or BFR, whose development he said was proceeding more swiftly than expected.

Obama vows to send people to Mars by 2030

WASHINGTON (Reuters) – U.S. President Barack Obama on Tuesday vowed to help send people to Mars within the next 15 years, pledging to work with private companies to “to build new habitats that can sustain and transport astronauts on long-duration missions in deep space.”

“We have set a clear goal vital to the next chapter of America’s story in space: sending humans to Mars by the 2030s and returning them safely to Earth, with the ultimate ambition to one day remain there for an extended time,” Obama said in an opinion piece for CNN posted to its website.

Human flights to Mars still at least 15 years off: ESA head

Monitors in the ESOC

By Maria Sheahan and Ashutosh Pandey

DARMSTADT, Germany (Reuters) – Dreaming of a trip to Mars? You’ll have to wait at least 15 years for the technology to be developed, the head of the European Space Agency (ESA) said, putting doubt on claims that the journey could happen sooner.

“If there was enough money then we could possibly do it earlier but there is not as much now as the Apollo program had,” ESA Director-General Jan Woerner said, referring to the U.S. project which landed the first people on the moon.

Woerner says a permanent human settlement on the moon, where 3D printers could be used to turn moon rock into essential items needed for the two-year trip to Mars, would be a major step toward the red planet.

U.S. space agency NASA hopes to send astronauts to Mars in the mid-2030s and businessman Elon Musk, head of electric car maker Tesla Motors, says he plans to put unmanned spacecraft on Mars from as early as 2018 and have humans there by 2030.

The ESA’s Woerner said it would take longer.

A spacecraft sent to Mars would need rockets and fuel powerful enough to lift back off for the return trip and the humans would need protection from unprecedented physical and mental challenges as well as deep-space radiation.

Woerner would like to see a cluster of research laboratories on the moon, at what he calls a “moon village”, to replace the International Space Station when its lifetime ends and to test technologies needed to make the trip to Mars.

That could be funded and operated by a collection of private and public bodies from around the world, he said in an interview at the ESA’s Operations Centre.

“There are various companies and public agencies asking to join the club now, so they want to do different things, resource mining, in situ research, tourism and that kind of stuff. There is a big community interested,” he told Reuters.

“The moon village is a pit stop on the way to Mars,” Woerner said, adding that new 3D printing technology could be used to build material and structures out of rocks and dust, doing away with the cost of transporting everything needed for a mission.

“To test how to use lunar material to build some structures, not only houses, but also for a telescope or whatever, will teach us also how to do it on Mars,” he said.

The ESA, working with Russia, in March sent a spacecraft on a seven-month journey as part of the agency’s ExoMars mission, which will use an atmospheric probe to sniff out signs of life on Mars and deploy a lander to test technologies needed for a rover scheduled to follow in 2020.

Woerner said Europe was looking at ways to lower the cost of launches but did not plan to copy Elon Musk’s SpaceX, which is trying to develop relatively cheap, reusable launch vehicles.

“We should not copy. To follow and copy does not bring you into the lead. We are looking for totally different approaches,” Woerner said, adding the ESA was examining all manner of new technologies, including air-breathing engines that do not need to tap into oxygen from a spacecraft’s tank.

Astronauts get first look inside space station’s inflatable module

The Bigelow Expandable Activity Module shown at Bigelow Aerospace in Las Vegas Nevada

By Irene Klotz

CAPE CANAVERAL, Fla. (Reuters) – Astronauts aboard the International Space Station on Monday floated inside an experimental inflatable module that will test a less expensive and potentially safer option for housing crews during long stays in space, NASA said.

Station flight engineers Jeff Williams and Oleg Skripochka opened the hatch to the Bigelow Expandable Activity Module, or BEAM, at 4:47 a.m. EDT (0847 GMT) on Monday.

Designed and built by privately-owned Bigelow Aerospace, BEAM is the first inflatable habitat to be tested with astronauts in space. The Las Vegas-based firm previously flew two unmanned prototypes.

BEAM was flown to the space station aboard a SpaceX Dragon cargo ship in April and inflated to the size of small bedroom on May 28. It is scheduled to remain attached to the station, a $100 billion research laboratory that flies about 250 miles (400 km) above Earth, for two years. Wearing face masks and headlamps, Williams and Skripochka floated inside the darkened module for the first time to collect air samples for analysis and retrieve engineering data from BEAM’s inflation.

Williams told flight controllers the module looked “pristine,” mission commentator Gary Jordan said during a NASA TV broadcast. Williams also said it was cold inside BEAM, but that there was no sign of condensation on the walls, Jordan said.

Astronauts will return to BEAM on Tuesday and Wednesday to install temperature and radiation sensors as well as instruments to collect data from any micro-meteoroid or orbital debris impacts.

BEAM’s hatch will remain closed except when astronauts go inside the module six or seven times per year to retrieve recorded data, NASA said.

Lightweight inflatables, which are made of layers of fabrics and a protective outer shield, are far less costly to launch than traditional metal modules. They may also provide astronauts with better radiation protection.

“This technology can be used in future designs for a mission to Mars,” Jordan said. Bigelow Aerospace is aiming to fly inflatable space modules 20 times larger than BEAM that can be leased out to companies and research organizations.

Skywatchers can see close, bright Mars looming large this month

The planet Mars taken by the NASA Hubble Space Telescope when the planet was 50 million miles from Earth

By Irene Klotz

CAPE CANAVERAL, Fla. (Reuters) – Mars makes its closest approach to Earth in a decade this month, providing sky-watchers with a celestial show from dusk to dawn starting this week, NASA said on Thursday.

The red planet already looms large in the nighttime skies, appearing as a bright, fire-yellow, star-like light as a result of Earth, the third planet from the sun, and Mars, the fourth, coming into close alignment.

“Just look southeast after the end of twilight, and you can’t miss it,” Sky Telescope magazine editor Alan MacRobert said in a statement.

This alignment occurs about every 26 months.

On Thursday, the U.S. National Aeronautics and Space Administration (NASA) released a photograph of Mars taken by the Hubble Space Telescope as the planet neared Earth last week. The detailed image showed polar caps and clouds above Mars’ rust-hued landscape.

On May 30, Mars and Earth will come than they have been in a decade, NASA said. Mars will be 46.8 million miles (75.3 million km) away.

The distance between Earth and Mars reaches up to about 250 million miles (400 million km) depending on the ever-changing positions of the two planets as they circle around the sun.

If skies are clear, Mars will be visible for much of the night and can be easily seen without a telescope or binoculars.

Mars has been even closer to Earth before. In August 2003, Earth and Mars were just 35 million miles (56 million km) apart, a quirk stemming from the planets’ slightly oval-shaped orbits around the sun.

It will be almost 300 years before the planets come that close again.

APE CANAVERAL, Fla. (Reuters) – SpaceX plans to send an unmanned Dragon spacecraft to Mars as early as 2018, the company said on Wednesday, a first step in achieving founder Elon Musk’s goal to fly people to another planet.

The program, known as Red Dragon, is intended to develop the technologies needed for human transportation to Mars, a long-term goal for Musk’s privately held Space Exploration Technologies, as well as the U.S. space agency NASA.

“Dragon 2 is designed to be able to land anywhere in the solar system,” Musk posted on Twitter. “Red Dragon Mars mission is the first test flight.”

The announcement marks the first time SpaceX has targeted a date for its unmanned mission to Mars, company spokeswoman Emily Shanklin wrote in an email to Reuters.

The company said it will provide details of its Mars program at the International Astronautical Congress in September.

Musk started SpaceX, as the company is known, in 2002 with the goal of slashing launch costs to make Mars travel affordable. SpaceX intends to debut its Mars rocket, a heavy-lift version of the Falcon 9 booster currently flying, before the end of the year.

Five planets visible in pre-dawn sky for first time in 11 years

Early-morning stargazers will have the rare opportunity to observe five planets at the same time during the next few weeks, according to a recent post on astronomy website EarthSky.org.

EarthSky says it’s the first time in more than 11 years that the five brightest planets — Mercury, Venus, Mars, Jupiter and Saturn — will simultaneously appear in the sky above Earth.

People had their first chance to catch the five planets before sunrise this morning, according to EarthSky, and the rare sight can be witnessed just before dawn every day through February 20.

The planets can be seen without a telescope or binoculars from anywhere on Earth, the EarthSky post says. Unclear skies could prevent some people from observing the spectacle on certain days.

Evidence of Water Found on Mars Announced by NASA

The strongest evidence yet of water on mars was announced by NASA Monday afternoon.

“Our quest on Mars has been to ‘follow the water’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, associate administrator at NASA’s Science Mission Directorate in Washington, D.C. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

Although scientists are not sure where the water comes from, liquid water runs down the crater walls over the summer months and leave dark stains on the Martian terrain that have been measured hundreds of meters downhill before they dry up in the autumn when temperatures drop.  

Researchers say the discovery raises the chances of this being home to some form of life.  

Mars Warmer Than 14 States

The current weather front in the northern part of the U.S. may have many residents signing up for a mission to Mars.

The high temperature on the red planet on Thursday was 17.6 degrees, warmer than the high temperatures in 14 northern U.S. states.

Residents of northern states have been fighting bitter cold and wind chills that have caused major outbreaks of frostbite.  Hospitals have been reporting people coming in for treatment who didn’t realize how bad the bitter cold would impact their bodies.

Winter Storm Gorgon is moving off the U.S. east coast this weekend and warmer temperatures are expected to cover the northern states.  However, the resulting front could bring massive amounts of snow to the Great Lakes  region with some models showing up to three feet of snow in some areas.

Wind chill readings of below zero were reported as far south as Alabama, Mississippi and North Carolina.

Many school districts around the nation cancelled their classes Thursday because of the dangerous cold.  Detroit reported a high of 3 degrees.  Green Bay, Wisconsin, where the Packers are to play a playoff football game this weekend, had a high of 6 degrees.  International Falls, historically one of the coldest spots in the continental U.S., reached a high of -1.
