NASA is working with Russia on a new space station

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.

Follow us on Google+ , Twitter and Facebook



A team of NASA researchers has found that 3D manufactured copper parts could withstand the heat and pressure required of combustion engines used in space launches.

The US space agency and California-based rocket and missile propulsion manufacturer Aerojet Rocketdyne (AR) conducted 19 hot-fire tests on four injector and thrust chamber assembly configurations at NASA's Glenn Research Centre.

"The successful hot fire test of engine components provides confidence in the additive manufacturing process and paves the way for full-scale development," said Tyler Hickman, lead engineer for the test at Glenn.

3D printing approach is changing the speed, cost and flexibility of designing and building future machines for space and earth applications.

The work is a major milestone in the development and certification of different materials used in the manufacturing process.

Copper alloys offer unique challenges to the additive manufacturing processes.

"Additively manufactured metal propulsion components are truly a paradigm shift for the aerospace industry," added Paul Senick, Glenn project manager.

This will improve efficiency and bring down the cost of space launches and other earth applications, he concluded.

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.

ISRO plans second mission to Mars in 2018

The Indian Space Research Organisation (ISRO) is planning to launch second mission to Mars with a lander and rover to carry out more experiments on the red planet.

The proposed plans come after the Indian space agency has successfully placed its unmanned Mars Orbiter Mission spacecraft to the Martian orbit in September.

ISRO satellite centre director Shiva Kumar was quoted by IANS as saying: "We plan to launch a second mission to Mars in 2018, probably with a lander and rover, to conduct more experiments for which we have to develop new technologies.

"We will be able to take the Mars-2 mission after launching the second mission to the moon (Chandrayaan-2) in 2016 with our own lander and rover, which will help us develop a separate lander and rover for the red planet."

The agency is looking to launch the programme in 2018 as the missions to Mars can be launched at two year intervals.

ISRO intends to have fully operational heavy rockets ready by then to carry communication satellites weighing around 3t into the geo-stationary orbits around the earth.

In line with this plans, the agency has developed the geo-synchronous satellite launch vehicle (GSLV Mark I-III) to launch heavier communication satellites.

GSLV Mark-III is scheduled to take its first partial test flight in early December.

ISRO chairman Radhakrishnan was quoted by The Hindu as saying that the test flight will lead to a 'future workhorse vehicle that will stay with us for many years'.

Tests will be conducted on unmanned crew module of the three-stage launch vehicle, to evaluate heating during its re-entry and its behaviour in the crucial space phase.

NASA rocket to click 1,500 images of Sun in 5 minutes

Follow us on Google+ , Twitter and Facebook




This image provided by NASA shows the sun emitting a significant X3.2-class flare erupting from the lower half of the sun, peaking at 5:40 p.m. EDT on Oct. 24, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly and captured images of the event.

A sounding rocket fitted with technology to gather 1,500 images of the Sun in flat five minutes is set for launch on Monday.

Capturing five images per second, the Rapid Acquisition Imaging Spectrograph Experiment (RAISE) mission will focus in on the split-second changes that occur near active regions on the Sun.

These are areas of intense and complex magnetic fields that can give birth to giant eruptions on the Sun that shoot energy and particles out in all directions, the U.S. space agency said in a statement.

“Even on a five-minute flight, there are niche areas of science we can focus on well. There are areas of the Sun that need to be examined with the high-cadence observations we can provide,” said Don Hassler, solar scientist at the Southwest Research Institute in Boulder, Colorado.

RAISE will create a kind of data product called a spectrogram which separates the light from the sun into different wavelengths.

“The Sun has been extremely active recently, producing several X-class flares in the past few weeks. The team will aim their instrument at one of these active regions to try to understand better the dynamics that cause these regions to erupt,” Mr. Hassler explained.

The team hopes to see how heat and energy move through such active regions, which, in turn, helps scientist understand what creates the regions and perhaps even what catalyses the sun’s eruptions.

RAISE’s launch time is planned for 2.07 p.m. (EST) from the White Sands Missile Range near Las Cruces, New Mexico.

"Unexpected Planet" Discovered by Yale Astronomers

Follow us on Google+



Astronomers have discovered a new planet that has a highly inconsistent orbit time around its Sun.

The low-mass, low-density planet, known only as PH3c, which is 2,300 light years away from the Earth, has an atmosphere loaded with hydrogen and helium.

The planet nearly escaped detection as PH3c does not have a consistent orbit time around its Sun due to the gravitational influence of other planets on its system.

“On the Earth, these effects are very small, only on the scale of one second or so,” said Joseph Schmitt, a graduate student at Yale University.

“PH3c’s orbital period changed by 10.5 hours in just 10 orbits,” explained Schmitt.

This inconsistency kept the planet out of reach for automated computer algorithms that search stellar light curves and identify regular dips caused by objects passing in front of stars, he said.

The researchers discovered the new planet with the help of Planet Hunters programme coordinated by Yale University and University of Oxford.

The programme, which has found over 60 planet candidates since 2010, enlists citizen scientists to check survey data from the Kepler spacecraft.

Not only did Planet Hunters spot PH3c, but the discovery also enabled astronomers to better characterise two other planets - one on each side of PH3c.

An outer planet PH3d is slightly larger and heavier than Saturn. An inner planet, PH3b may have a rocky composition like the Earth.

“Finding the middle planet was key to confirming the others and allowing us to find their masses,” Schmitt explained.

New Horizons to Explore Pluto

In January 2006, New Horizons was launched for its long journey to explore Pluto and its five known moons. This will be NASA’s first opportunity to explore the distant planet of which little is known since its 1930 discovery.

Pluto is the most famous resident of the Kuiper Belt, an area of space beyond Neptune that is filled with innumerable objects that are believed to be remnants of the formation of the solar system. A Dutch astronomer, Jan Oort, theorized that comets might originate from this distant region. Gerard Kuiper first envisioned the existence of icy objects beyond Neptune in 1951.

The Kuiper Belt is about 3 billion miles from Earth and is similar to the asteroids that orbit the sun between Mars and Jupiter.   The asteroid belt is filled with rocky objects whereas the Kuiper Belt’s objects are icy. Several dwarf planets, of which Pluto is one, exist in these far reaches of space. Dwarf planets are not only smaller than regular planets, but their lack of size does not give them the ability to clear space around them.

Currently in a hibernation state, New Horizons will awake and begin preparing for its encounter with Pluto on Dec. 6. The actual flyby will begin in January with the spacecraft’s closest encounter occurring on July 15, 2015. A scheduled trajectory adjustment burn was not deemed necessary and has left the craft with additional fuel.

The additional fuel has NASA officials searching for additional Kuiper Belt objects for New Horizons to explore. To identify potential targets, officials used the Hubble telescope to locate objects of interest. These targets had to be in line with Pluto so that additional use of fuel would not be required. The Hubble data identified three additional objects that will be tracked to ascertain their orbital path.

New Horizons crossed Neptune’s orbital path on Aug. 25. On Sept. 12 NASA, using the Long Range Reconnaissance Imager, began its initial preparatory testing of the approaching Pluto system. Hydra, a small moon of Pluto, was detected. It was not anticipated to view the moon until early in 2015. Locating Hydra this early in the process bodes well for the team’s ability to locate potential unknown moons or planetary rings.

New Horizons took 48 images, each lasting 10 seconds, of Pluto on two separate occurrences in July. While these images revealed Hydra, officials were unable to see Nix, another of Pluto’s moons. New Horizons was still 267 million miles from Pluto when these images were taken. Those images also revealed its largest moon, Charon. Some astronomers consider Pluto-Charon as a binary planet.

NASA has completed its detailed engineering review of the mission and has begun the process of planning for the approach science. By next month sequences for planetary approach will be developed. Each sequence serves as a two-week flight plan for the spacecraft and takes about eight weeks to develop, test and certify.

New Horizon’s exploration of Pluto and the Kuiper Belt is NASA’s first extensive look at this distant part of the solar system. Pluto was still classified as a planet when the mission initially launched. It has since been downgraded to a dwarf planet.
