NASA says Mars has liquid water

For the first time, NASA has confirmed the existence of liquid water on the surface of Mars, according to new research announced Monday. The finding stems from data and analysis by NASA’s Mars Reconnaissance Orbiter.

The Mars Reconnaissance Orbiter (MRO) has verified that the dark, seasonal streaks that have appeared on Mars’ surface come from briny water flows.

MRO found evidence of narrow channels containing water cut into cliff walls through Mars’ equatorial band, though the source and chemistry of the water is yet unknown. The streaks, or recurring slope lineae, appear during the warmer summer months on the Red Planet. They disappear when the temperature drops.

The findings advance the potentiality for life on Mars, researchers said. While it is likely that life exists in the crust of Mars, the new findings further the possibility of life closer to the surface of the planet, Alfred McEwen, a planetary scientist with Arizona State University, said during a NASA press conference.

Scientists had previously run into difficulties analyzing the streaks, which measure less than 16 feet, or 5 meters, wide. The MRO’s instruments were able to process trace measurements, and scientists successfully observed the findings thanks to a computer program that can focus in on individual pixels. MRO’s data was then compared with high-resolution images of the slopes. Scientists found a match between their locations and the presence of hydrated salts.

“We’re not claiming that we found … evidence of liquid water. We found hydrated salts,” said Lujendra Ojha, a graduate student at Georgia Institute of Technology and lead author of the report, published in the journal Nature Geosciences.

While NASA has rushed to announce the findings, Ojha expressed reserve.

“It’s a little bit over-the-top announcement by NASA,” Ojha said. “There’s so many mysteries to be solved about RSL (recurring slope line).”

The presence of water on Mars in the form of ice caps has been known for years. However, proof of liquid water on the Red Planet will have major ramifications for the study of Mars. It may mean that microbial life may still survive under the Martian surface, if there ever was any in the first place.

NASA’s announcement confirming that it found evidence of water flowing on the surface Mars was welcomed mostly by publicists at 20th Century Fox looking to promote “The Martian,” the upcoming Ridley Scott film starring Matt Damon.

Russia plans own space station

Russia announced plans Tuesday evening to continue operating the International Space Station until 2024 — but afterwards, it will take its modules away to form its own space station.

The ISS, which was assembled in orbit between 1998 and 2011, is made up mainly of modules owned by NASA and Roscosmos (the Russian space agency), along with some owned by Japan and Europe. Original plans called for it to be retired by 2020, but in January 2014, President Obama announced plans to extend its mission to 2024, and possibly to 2028.

That, however, depended on Russia’s cooperation, because under the station’s current configuration, modules from both countries are needed to operate it. Last May, due to tensions from economic sanctions imposed over the invasion of Ukraine, Russia threatened to pull out of the project in 2020.

The new announcement ensures that ISS will live on until 2024 — but puts the future of US-Russia cooperation in space in doubt.

Since 1975, when the US Apollo and Soviet Soyuz spacecrafts linked up in orbit, the US and Russia have worked together in space. And recently, as political tensions between the two countries have grown, space has remained one of few areas of cooperation.

If Russia goes through with this plan, though, the era of space cooperation might be over. NASA currently relies on Russia to ferry its astronauts to the ISS, but by 2017, it’s hoping that private American companies (SpaceX and Boeing) will be able to carry out these missions instead. Russia, meanwhile, says it plans to use several of its ISS modules to assemble its own, new space station, possibly as a precursor for human missions to the moon. NASA’s longer-term plans for crewed exploration are uncertain, but no proposals involve collaboration with Russia.

The good news is that in the short term, the complex, expensive ISS will continue to be used for research (helping scientists figure out, for instance, how to keep humans healthy in space) instead of being thrown away prematurely for political reasons. But the bad news for space exploration as a whole is that the world’s two most capable space programs might soon be competing with each other, instead of working together.

Britain stokes fear over ‘mysterious object’

Britain has warned that a “mysterious object was launched by the Russian military”.

The FT’s Sam Jones, Defence and Security Editor, reported that the Object 2014-28E is being tracked by western space agencies, “stoking fears over the revival of a defunct Kremlin project to destroy satellites”.

Jones, who specialises in anti-Russian propaganda, has numerous sources inside MI6.

 

For the past few weeks, amateur astronomers and satellite-trackers in Russia and the west have followed the unusual manoeuvres of Object 2014-28E, watching it guide itself towards other Russian space objects. The pattern appeared to culminate last weekend in a rendezvous with the remains of the rocket stage that launched it.

The object had originally been classed as space debris, propelled into orbit as part of a Russian rocket launch in May to add three Rodnik communications satellites to an existing military constellation. The US military is now tracking it under the Norad designation 39765.

Its purpose is unknown, and could be civilian: a project to hoover up space junk, for example. Or a vehicle to repair or refuel existing satellites. But interest has been piqued because Russia did not declare its launch – and by the object’s peculiar, and very active, precision movements across the skies.

Russia officially mothballed its anti-satellite weaponry programme – Istrebitel Sputnikov or satellite killer – after the fall of the iron curtain, though its expertise has not entirely disappeared. Indeed, military officials have publicly stated in the past that they would restart research in the event of a deterioration in relations with the US over anti-missile defence treaties. In 2010, Oleg Ostapenko, commander of Russia’s space forces, and now head of its space agency, said Russia was again developing “inspection” and “strike” satellites.

Moscow’s ministry of defence did not immediately respond to a request for comment.

“Whatever it is, [Object 2014-28E] looks experimental,” said Patricia Lewis, research director at think-tank Chatham House and an expert in space security. “It could have a number of functions, some civilian and some military. One possibility is for some kind of grabber bar. Another would be kinetic pellets which shoot out at another satellite. Or possibly there could be a satellite-to-satellite cyber attack or jamming.”

In a week when the European Space Agency’s Rosetta spacecraft landed a probe on a comet, the peregrinations of 2014-28E could seem insignificant, but they highlight an area of growing – if so far little publicised – concern for defence strategists: the weaponisation of space.

Having the ability to destroy or degrade an opponent’s satellite communications has been regarded as a powerful military capability since the space race began but, after the collapse of the iron curtain, many of the secret research projects Soviet and US engineers were working on were quietly shelved. In the past few years, however, interest in space weapons has revived.

“It would be odd if space were to remain the one area that [militaries] don’t get their hands on,” says Ms Lewis. Cyber attacks on satellites are already a reality, she points out: last week, hackers linked to the Chinese government infiltrated US federal weather satellites.

Russia has in the past been at the forefront of efforts to try to secure an international treaty to prevent weapons being deployed in space, but its efforts have fallen on stony ground.

Amid rapid advances by other foreign powers, and the recent deterioration in relations between Moscow and the west, plans to revive the IS programme would make strategic sense, said one Russian military expert.

As far back as 2007, the Chinese showed they had the ability to shoot down satellites with rockets and in 2008 the US demonstrated it had the same capability.

More recently, in May this year, a Chinese satellite known as Shijian 15 began to exhibit unusual propulsion capabilities and eventually intercepted another Chinese satellite, Shijian 7.

“The experiment was linked to the possible use of a remote capture arm and close proximity operations,” said Max White, a member of the Kettering group of astronomers, which made a name for itself in the 1960s by pinpointing the location of Soviet spy satellite launches. “Both can have peaceful as well as military nuances, with the former for refuelling in space, and the latter for disabling an active payload belonging to a foreign nation, potentially without causing a debris cloud.

“Whether the Russians feel they need to demonstrate such capability is a matter for debate,” Mr White added. He, too, has been following the activities of object 2014-28E.

In a signal of international sensitivities over the prospect of anti-satellite technologies being rapidly developed, a Chinese missile test this year drew an unusually fiery response from the Pentagon. US authorities said they had “high confidence” that a July launch was a test for a ground-based weapon to strike a satellite, accusing the Chinese of “destabilising actions”. China’s test was later also condemned by the EU.

Russia will start deploying its own orbital space station in 2017, using part of the modules constructed for the International Space Station (ISS), Kommersant newspaper reported Monday, citing a space engineering source.

“The new station will be located geometrically more advantageous, allowing an extended field of view of the Earth’s surface. As much as 90 percent of Russia’s territory and the Arctic offshore area will be visible from the station,” the source said, noting that the ISS’ field of view covers no more than 5 percent of the region.

In May, Russian Deputy Prime Minister Dmitry Rogozin announced that Moscow was not planning to use the International Space Station after 2020 and would instead re-focus its funding on more promising new space projects.

Toy tiger cub joins space ride

Beloved by generations of Russian children, Goodnight Little Ones is the longest-running children’s show in the world and has featured virtually the same evening format since it started in 1964.

A new addition to the show will be Mur to join Khryusha, a piglet (introduced in 1970), Stepashka, a hare (introduced the same year), Philya, a dog, introduced in 1968, Karkusha, a crow, introduced in 1982, and Mishutka, a bear, introduced in 2002.

Mur is a tiger cub.

‘The ideas were discussed with children and their parents, and the opinion of psychologists was asked. It is important that the little TV viewers should take a fancy to the new personage because it is coming to the TV show for good.’

He explained: ‘The idea to take an Amur tiger cub ‘on the staff’ came into our mind after an interview with President Putin, who told of his active support of several ecological programmes to protect rare animal species on the verge of extinction.

He said that these animals are our national treasure and that they need protection.

He admitted that the tiger cub proposal initially ‘sounded a bit surprising’ but ‘we looked carefully at this idea, we realized it was a bingo!’

A new Soyuz crew will take the plushy toy tiger cub to the International Space Station, ISS, as part of an action to call public attention to rare species.

The action has been organized by the Russian Space Agency Roskosmos and two non-profit organizations – the Amur Tiger and the Far Eastern Leopards centers.

A new ISS crew whose composition was approved by a state commission earlier on Wednesday is to take off from Baikonur on September 26. For the first time in ten years, the crew will comprise a woman – Elena Serova. The ISS expedition will last for 168 days.

“On the eve of the International Tiger Day, Roskosmos has decided to support an environmental action designed to call public attention to rare species. The Amur tiger cub named Mur and a far eastern leopard will fly to the International Space Station,” Yuri Lonchakov, the head of the space training center, said.

In addition to that, the crew, comprising Alexander Samokutayev, Elena Serova and Barry Wilmore, will take a flask with water taken from the River Kazanka in Kazan, the capital of the Republic of Tatarstan, in honor of the 16th FINA World Championship in aquatics to be hosted by Kazan in 2015.

The crew of Maxim Surayev which the new ISS expedition in going to replace will return the flask with water back to Earth. The ‘space’ water will later be handed over to a museum.

Galileo flounders on software error

The failure of the European Union’s Galileo satellites to reach their intended orbital position was likely caused by software errors in the Fregat-MT rocket’s upper-stage, Russian newspaper Izvestia reported Thursday.

“The nonstandard operation of the integrated management system was likely caused by an error in the embedded software. As a result, the upper stage received an incorrect flight assignment, and, operating in full accordance with the embedded software, it has delivered the units to the wrong destination,” an unnamed source from Russian space Agency Roscosmos was quoted as saying by the newspaper.

Both the upper-stage and the software for it were developed by a Moscow-based government-owned corporation, the Academician Pilyugin Scientific-production Center of Automatics and Instrument-Making, or the Academician Pilyugin Center.

On August 22, the launch of Galileo’s Full Operational Capability (FOC) satellites aboard a Russian Soyuz rocket took place at the European Union’s spaceport in Kourou, French Guiana. The satellites, which are part to the Galileo program, designed to provide a European alternative to the American GPS and Russian Glonass navigation systems, have been placed in a lower orbit than expected.

The Arianespace satellite launch company, the European Space Agency (ESA) and Roscosmos are currently investigating the incident.
