SpaceX’s rocket just exploded. Here’s why that’s such a big deal.

An unmanned SpaceX Falcon 9 rocket bound for the International Space Station exploded a couple of minutes after liftoff Sunday morning. It was the third cargo mission to the space station to be lost in recent months.

Elon Musk, SpaceX's founder tweeted that "there was an overpressure event in the upper stage liquid oxygen tank." He added: "That's all we can say with confidence right now. Will have more to say following a thorough" analysis.





NASA officials said it was not clear what caused the explosion. During an afternoon press conference William Gerstenmaier, NASA's associate administrator for human exploration and operations, said there was "no negligence here."

The three failures from three different launch providers show "the challenges facing engineering and the challenges facing space flight in general."

The rocket took off from Cape Canaveral, Fla., at 10:21 a.m., and everything seemed fine until 2 minutes at 19 seconds. Then video of the launch showed harrowing, if now familiar, images of a rocket exploding into a plume of smoke. The Falcon 9 was carrying more than 4,000 pounds of food and supplies to the space station, where American Scott Kelly is spending a year. There were no astronauts onboard.


The explosion also lost many student experiments and a water filtration system. Also onboard was a piece of hardware that would be used to help two new crew vehicles dock to the station.

Russia sets out Moon landing ambition, leaves Mars plans to Nasa

Russia, which put the first man into orbit in 1961, sees the Moon as a base for deeper space missions, Komarov said


Roscosmos plans to send 3 unmanned craft to the Moon before a Russian cosmonaut attempts a landing.
Russia’s state space agency chief is shooting for the Moon, three years after a predecessor warned that the country was on the verge of losing its competitiveness in the industry.
A manned lunar mission in 2029-2030 is Russia’s priority, while there are no “current stage” plans for a journey to Mars, Igor Komarov, head of the Federal Space Agency or Roscosmos, said in an interview in St. Petersburg last week.
“Nasa has Mars as the priority,” Komarov said. “We at this stage are making the Moon our priority. We can be good in rounding each other out and working jointly on this programme.”
Komarov’s ambition of landing a Russian on the Moon contrasts with former Roscosmos chief Vladimir Popovkin’s warning in 2012 that the country’s space industry risked being uncompetitive within three or four years without “urgent measures.”
Russia, which put the first man into orbit in 1961, sees the Moon as a base for deeper space missions, Komarov said. It plans to send three unmanned craft to the Moon before a Russian cosmonaut attempts a landing, though Earth’s nearest neighbour shouldn’t become the object of a technological race between Russia and the US, he said.
Space partners
“We see it as a joint project and are ready to invite our partners for it to be done,” said Komarov, 51, who was appointed Roscosmos chief in January after it merged with United Rocket and Space Corp. that he headed. Previously in charge of Russia’s OAO AvtoVAZ carmaker for four years until 2013, he was given the task of overhauling the country’s space industry following a series of recent accidents during launches.
Amid worsening ties between Russia and the US over the conflict in Ukraine, space research could provide an example of cooperation that doesn’t depend on politics, Komarov said.
Sanctions imposed by the US and the European Union didn’t affect cooperation in running the International Space Station, he said. Increased equipment prices and delays in international projects show that Russia’s space industry hasn’t completely avoided the tensions and it’s now forced to seek greater cooperation with fellow members of the BRICS group that includes India, China, Brazil and South Africa, according to Komarov.
“Global projects are easier to implement together,” he said. “Less investment is needed, it benefits everyone.”
Humanity will always be united by the “eternal dream” of searching for civilizations on other planets, Komarov said.
“I do believe in the existence of an intellect different from ours,” he said.

NASA is working with Russia on a new space station

STS-116_spacewalk_1

Astronauts Repairing Space Module

Russia is teaming up with the USA to build ISS 2.0 once the current one's funding runs out in 2024 -- at least according to Russia Today and state news agency TASS. The country's space agency, Roscosmos threatened in February to use the Russian ISS modules as a platform for a new base of its own after 2024, but now it looks like there will be a followup collaboration.

This time around, both parties are looking for participation from other countries, as well as private industry, and are apparently even eyeing a team-up for potential missions to Mars. Russian news outlets report the announcement came during a news conference Saturday following the launch of a year-long mission (video of the launch and subsequent ISS docking is embedded after the break) to the current International Space Station.

NASA Statement -
We are pleased Roscomos wants to continue full use of the International Space Station through 2024 -- a priority of ours -- and expressed interest in continuing international cooperation for human space exploration beyond that. The United States is planning to lead a human mission to Mars in the 2030s, and we have advanced that effort farther than at any point in NASA's history. We welcome international support for this ambitious undertaking. Today we remain focused on full use of our current science laboratory in orbit and research from the exciting one-year mission astronaut Scott Kelly just began, which will help prepare us for longer duration spaceflight.

Chief Komarov, who was there for the US-Russia year-long ISS mission launch, reportedly said: "We have agreed that Roscosmos and NASA will be working together on the program of a future space station." In addition to building a new ISS, sources say the agency's partnership also entail working on a joint Mars mission. In the same event, NASA chief Charles Bolden is quoted saying: "Our area of cooperation will be Mars. We are discussing how best to use the resources, the finance, we are setting time frames and distributing efforts in order to avoid duplication."

So far NASA hasn't announced or confirmed anything through its official channels. We've contacted the agency for comment and will update this post if we hear anything.

Russia to create joint orbital station with India, China

brics-logo1

Russia is exploring the possibility of a joint manned orbital station with India and China as part of a common strategy to create technological alliances and may take up the matter with the two Asian space giants in July.
"Moscow could propose to China and India to create a joint manned orbital station at the summit of the BRICS emerging economies in Russia's Ufa in July," a document drafted by the expert council at Russia's military and industrial commission said.
The experts recommend "working out the possibilities of an international manned project with BRICS (Brazil, Russia, India, China, and South Africa) countries as part of a common strategy of creating technological alliances", Itar Tass reported.
The proposal comes after months of speculation that the crisis in Ukraine would doom U.S.-Russia space cooperation. For two decades this effort has largely been focused on the International Space Station project (ISS), which is due to end in 2020. NASA has proposed extending it to 2024, but Russia has suggested it might duck out and instead build its own space station — possibly with the participation of China.
The BRICS project would be roughly analogous to the ISS, a $150 billion project involving 15 nations. Anchored by the United States and Russia, the world's leading spacefaring powers, the ISS allows countries with less advanced spaceflight capabilities to either join onto the station's Russian and American segments or contribute smaller segments.
A BRICS space station would likely emerge from a similar two-nation partnership, again with Russia in a driver's seat. The Military-Industrial Commission recommended approaching either China or India — both countries that have well-developed and increasingly ambitious space programs. The proposal would then allow other BRICS members to join.
India has yet to put a man in space without hitching rides on other nations' rockets. Last year, it demonstrated its rising capabilities after launching an unmanned satellite to Mars on a shoestring budget.
China is perhaps the best partner for such a project. China already launches its own astronauts into space, and is designing its own medium-sized space station. The placement of Russia's new Vostochny Cosmodrome in Russia's Far East also makes close cooperation with China far easier.

The agency will use the partnership to end dependency on Russia

SpaceX has completed the first certification milestone in its CCP commitment, and will spend much of 2015 testing abort solutions for its formerly cargo-only Dragon capsule. (Abort procedures are more critical in crewed missions.) A launchpad abort will be tested in the next two months at Cape Canaveral, and an in-flight abort test will follow "later this year," according to SpaceX President and COO Gwynne Shotwell. Uncrewed missions to the ISS with the new capsule will start in 2016, and the company is still working out the makeup of its first test flight crew.

"I DON'T EVER WANT TO HAVE TO WRITE ANOTHER CHECK TO ROSCOSMOS."

The company is also working on outfitting its Dragon capsule with propulsive landing, Shotwell said, which could improve reusability by dispensing with the need to splash down in water. Instead, the capsule would land right at Johnson Space Center, using rockets on the bottom to help control the descent. That's not the only new technology the company is working on. It hopes to outfit its Falcon 9 rockets with wings and retrorockets so they can land on autonomous barges in the ocean.

Boeing has completed the first two certification milestones for its CST-100 spacecraft. NASA has signed off on parts of its commercial crew operation, including designs for the control center, training systems, flight simulators, and software. Boeing has also started building its crew access tower on the Atlas V launchpad, and that construction will continue in between uncrewed Atlas V launches.

The CST-100 will undergo a critical design review in March, and if approved, will let the company launch "full-bore" into manufacturing, according to VP and General Manager of Boeing Space Exploration John Elbon. Boeing's spacecraft can fit up to seven crew members, and is also being designed with reusability in mind. According to Elbon, the plan is for the capsule to be recovered, refurbished, and reused up to 10 times.

When asked how this all fits in with the 2016 budget, Bolden said he's "very optimistic." "Congress has, I think, kind of started to understand the critical importance of commercial crew and cargo. They've seen, as a result of the performance of our providers, that this is not a hoax. It's not a myth. It's not a dream," he said. "It's something that really is happening."

Three crew members of the International Space Station have safely returned to Earth aboard a Soyuz-13M spacecraft, bringing back good memories and results of their 165-day shift in orbit – including a space-born generation of experimental fruit flies.

The spacecraft carrying the commander of the ISS Expedition 41 Russian cosmonaut Maksim Surayev, as well as two flight engineers, NASA astronaut Reid Wiseman and ESA astronaut Alexander Gerst, landed some 80 km from Arkalyk, Kazakhstan.

As part of their mission, the crew completed some 2,640 orbits covering more than 70 million miles and have participated in a number of experiments, including breeding of fruit flies that could potentially shed light on long-term space flight effects on human beings.

Russian Cargo Ship Lifts Off For Space Station

russia

An unmanned Russian cargo ship successfully lifted off for the International Space Station (ISS) on October 29.

The Progress 57 craft was launched atop a Soyuz rocket at 8:09 a.m. Prague time from the Russian-leased Baikonur facility in Kazakhstan.

"Everything looks good on the Soyuz booster and the Progress resupply ship," an announcer on the U.S. space agency's NASA TV said.

The launch came nine hours after a privately operated rocket exploded seconds after liftoff in the United States, causing the loss of cargo ship that was also bound for the ISS.

The explosion of the Antares was the first such accident since NASA turned to private operators to deliver cargo to the station, breaking a Russian monopoly that followed the retirement of the U.S. space shuttle fleet in 2011.

The Progress is delivering nearly three metric tons of propellant, oxygen, water, and other supplies to the station.
