Here’s what it’s like to live in space….

A $US150-billion contraption floating 270 miles above Earth is one of the most impressive achievements of humankind.

It’s called the International Space Station (ISS), and a rotating astronaut crew has occupied it since 2000. The work of those astronauts has yielded some incredible scientific insights.

Astronaut is not a profession where you get to go home at the end of the day though. One ticket from Earth to the ISS costs about $US70 million, so normally each crew lives and works on the station for a six-month shift.

Right now NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko are in the middle of a year-long shift aboard the ISS. They will be the first humans to spend a consecutive year living in space.

But what is it like to actually live on the ISS?

The first step to living in space is getting there. All astronauts hitch a ride to the ISS on board a giant space shuttle that launches from Russia.

NASA

The shuttle takes astronauts all the way up to the ISS, which floats about 250 miles above the planet.

NASA

The station is a system of labs, living quarters, and control rooms, and it spans about the length of a football field. A rotating crew of six astronauts share the space.

NASA

The ISS is hurtling around the Earth at about 17,150 miles per hour. That extreme velocity puts the ISS in a constant free fall around the planet.

So everything on board experiences weightlessness, including the astronauts.

So they get around the station by floating. Which means sometimes it’s too hard to resist the temptation to strike a Superman pose.

Weightlessness causes a lot of weird problems though — the kind of problems we never experience here on Earth thanks to gravity.

NASA

For example, sweat doesn’t evaporate. Instead, it pools on astronauts’ bodies, so they are constantly toweling off sweat. You can see sweat droplets escape from this astronaut’s towel after he wipes his head.

If objects escape inside the ISS, they can float away, get lodged in equipment, and cause malfunctions.

For example, even small tasks like clipping your nails become a problem. Astronauts clip them near a vent, so that tiny pieces of nail don’t end up floating all over the station.

RAW Embed

Water is also difficult to manage. It likes to stick together in a big blob.

So washing and showering is a challenge. Astronauts squirt a few lines of water on their skin and hair and then use no-rinse soap and shampoo to clean themselves.

The station only gets resupplied every few months, so astronauts have to be mindful of their supplies. Luckily, over 90% of the water on board gets recycled and reused.

That includes everything from dirty wash water, water from astronauts’ breath, and yes, even urine is recycled. It’s all sent through this high-tech water filter on board.

YouTube/Canadian Space Agency

The water is perfectly safe to drink after it’s run through the filter (it’s actually cleaner than the water we drink on Earth), but many astronauts say they try not to think about it too much when they refill their water pouches.

YouTube/Canadian Space Agency

Getting back to that urine thing, ‘How do you go to the bathroom?’ is one of the most common questions astronauts get.

YouTube/ESA

If you’re going number one, it gets sucked into this tube through the yellow nozzle.

YouTube/ESA

Things are little more complicated when you need to go number two. There’s a tiny seat, a container for the waste, and a suction pump.

YouTube/ESA

Once you do your business and suction it away, you have to change out the ‘poop bag’ for the next person.

YouTube/ESA

Still, all the complications that come from weightlessness don’t get in the way of what astronauts are really there for. They spend most of their time working on various research projects and repairing the station.

NASA

Sometimes that even involves venturing out into the dangerous vacuum of space. Trips outside the station are called ‘spacewalks,’ and they take a lot of preparation and safety training.

NASA

One wrong move and an astronaut could just float off into the vacuum of space (like George Clooney in ‘Gravity’). They also have to watch for leaks in the spacesuits that protect them from the bitterly cold temperatures and radiation in space.

NASA

When they aren’t working, astronauts still have to stick to a pretty tight schedule. They have mandatory workouts so they don’t lose too much muscle mass in the weightless environment. (Since they don’t have to fight gravity, they get a lot less exercise while moving around.)

You can easily lift hundreds of pounds in a weightless environment, so astronauts have a cleverly designed machine for weight lifting.

After a good work out, you gonna eat. Space meals are stored in dehydrated packets. Once you add a little water, dinner is served.

And the menu isn’t half bad. Here’s an astronaut enjoying a milkshake.

NASA

After dinner it’s time for bed. The middle section of the station is where most of the crew sleeps. Labs and work spaces make up the rest of the structure, and the giant yellow panels collect sunlight to help power everything.

YouTube/Canadian Space Agency

Each astronaut has their own tiny room that includes a work space and a sleeping bag strapped to the wall. You can see on the screens that it appears astronaut Scott Kelly is chatting on Facebook.

NASA

Sleeping in space is hard to get used to since you don’t feel the sensation of lying down. Astronauts zip themselves into a sleeping bag every night so they don’t float around in their sleep.

And they have to keep careful track of their sleep schedule since days don’t pass the same on the ISS as they do on Earth. The station is whizzing around the planet so quickly that the crew sees about 16 sunrises and sunsets during a 24-hour Earth day.

NASA

When it’s time to return to Earth, a shuttle flies up to the station to pick up the astronauts. Then they parachute back down to Earth in a landing pod.

NASA

Astronauts are a little wobbly on their feet when they first land, but it doesn’t take long to readjust to a weighted environment.

NASA

Living on the ISS is no picnic, but it’s a once in a lifetime opportunity. Most astronauts say they wouldn’t trade the experience for anything.

This is the change London Heathrow Airport has been waiting for…

Heathrow Skitch

London’s Heathrow Airport is one of the busiest hubs in the world and serves as a major connecting point for traffic between Asia and Africa with North America.

As Britain’s main international airport, Heathrow has been working hard to upgrade its facilities. In recent years, the airport has opened two brand new terminal buildings and have conducted significant renovations to others.

However, the greatest constraint on the airport has been it’s lack of runways. Although more than 72 million passengers pass through Heathrow every year, the facility still operates using just two runways.

However, if Heathrow’s latest expansion plans are approved, things are about to change for airport.

At first, the airport wasn’t much to look at. Its passenger terminals were just tents.

Heathrow Airport

By the 1960s, the airport’s permanent terminal buildings entered service. Heathrow also abandoned its ‘Star of David’ layout, keeping only the northern and southern runways.

Heathrow development came just in time for the arrival of the jet set! Along with celebrities such as The Beatles and …

Today, the airport is the primary international hub serving London and much of England.

The airport is home to Virgin Atlantic Airways and …

Heathrow Airport

… British Airways.

… Terminal 5 facilities

But what hasn’t changed in the last half century are its two runways.

But that may be ready for an update if the Airport’s new expansion proposal is approved this December.

The expansion would include a third runway built at the north of the airport; it would increase Heathrow’s capacity from 470,000 flights a year to 740,000.

The airport also wants to build a new terminal to the west of Terminal 5.

The expansion would also dramatically alter Heathrow’s central terminal area.

The transformed central terminal area will feature new hotels, office buildings and …

… green space for passengers.

The new hotel facilities will be located just a few minutes away from the terminals.

The proposed development plan also calls for improvements to road and rail access to the airport.

The expansion of London Heathrow has been a contentious topic. Although there have been discussions about building a completely new airport for decades, the British government recommended improvements to Heathrow as the preferred way to increase airport capacity.

Mumbai Airport Recruits Trained Therapy Dogs To Bring A Smile On Passenger’s Face…

Airports are exciting places of activity, but at times they also can be overwhelming for some fliers.

Recently, Chhatrapati Shivaji International Airport brought in two legitimate, trained therapy dogs to help ease the stress of travelling.

_0e716024-6cad-11e5-9358-ce0f694bc37c

Mumbai airport is possibly the first in the country to employ animals that would help ease travellers’ anxieties about returning to the skies. Earlier, therapy dogs were used to comfort special children and traumatised adults at US airports after the 9/11 attacks.

 

Goldie and Pepe, trained by the Animal Angels Therapy Centre in Pune, can sense a person’s mood by sniffing them.

_0f34d2f2-6cad-11e5-9358-ce0f694bc37c

Their mission is to put a smile on every passenger’s face they interact with.

 

This is what a Chicago-bound flier who came to bury his dead mother wrote in the feedback form:

“What an amazing and needed facet of airports. After a long painful day at the Mumbai airport, Goldie and Pepe brought ‘humanity’ into an otherwise dehumanising experience.”

 

therapy-dogs_38e5474e-6cad-11e5-9358-ce0f694bc37c

Of course, not everyone is a dog lover. Some people would feel less stressed at an airport if they could cuddle with a cat.

But, let’s admit it, passengers will now have a PAWSitive experience at the Mumbai airport! 🐾

Icon A-5: The Folding Airplane….

The Icon A-5 is a whole new aviation concept. It is designed to be a personal airplane aimed at the domestic leisure market – and people don’t need to be experienced pilots to fly it. The A-5 intends to simplify the flying process so much that anyone can pick up the skills necessary to fly the plane quickly and easily, and it has a whole stack of sophisticated safety features to help it achieve this goal. The aircraft has been in development since 2008 and is moving towards general release, having passed through the first of the necessary regulatory checks. Let’s have a look at this incredible concept and see a video of the A-5 in action.

Icon A-5

Image: iconaircraft.com
If you have ever dreamed of owning your own plane, but don’t want the added hassle of huge storage costs, long periods of training and complicated dashboards full of buttons, then the Icon A-5 is designed with you in mind. The dashboard of the plane looks more like something that you would find in the modern sports car, than an airplane, and aims to keep things as simple as possible. The A-5 has been described as the aviation industry’s answer to the Tesla.

Icon A-5 dashboard

The aircraft can take off and land on either water or gravel, and is genuinely amphibious. It features a carbon-fiber airframe, retractable undercarriage, and is powered by a three-bladed pusher propeller. The plane is meant to appeal to ‘weekend warriors’ who would savor the thrill of flying, and use the plane to reach remote lakes and rivers. The company’s head of sales, Craig Bowers believes the plane will be at the forefront of the ‘next powersport’. It can be viewed as the latest expensive toy in a list that historically includes sports cars, supercars, jet skis and private yachts.

Icon A-5

Image: iconaircraft.com
Of course, flying is inherently dangerous and if people don’t know what they are doing then it could turn out very badly indeed. For that reason, the designers have attempted to ‘fool-proof’ the plane to prevent accidents. Among the many safety features are a unique ‘angle of attack’ gauge that lets the pilot know if they are flying safely relative to the conditions. Engineers have also designed the plane to be resistant to spins and stalls. If the pilot makes a mistake and stalls the engine, the plane will continue to glide rather than nosedive, due to its specially designed wings.

Icon A-5

Image: iconaircraft.com
Of course, it wouldn’t be suitable for the general adventure sport market if it wasn’t easy to store and transport. Engineers have tried to satisfy this need – and they have been innovative in doing so. The wings of the A-5 fold inwards to make the machine much more compact so it can be carried on a trailer. By the same logic, the plane could also be feasibly stored in a garage – although with a length of 23 feet (7 meters), you would need a fairly large garage.

Icon A-5

Image: iconaircraft.com
The Icon A-5 is officially classed as a light-sport aircraft and features some impressive specifications. It has room for one passenger in addition to the pilot, a range of around 345 miles (556km) per journey and a maximum speed of 211mph (194km/h). The maximum take-off weight is 1,510lbs (685kg), meaning there is room for 550lbs (249kg) of ‘useful load’ (passenger weight, baggage etc.).

Before you get too excited, the Icon A-5 does of course come at a high price. The first batch of models are being sold for $250,000, although the company intends to sell later batches at the lower (but still significant) price of $197,000. That said, the plane is the first of its type and it remains to be seen whether the concept will catch on, leading to more affordable but similar offerings in years to come. The company behind the design is currently busy earning all the necessary Federal Aviation Association approvals ahead of the plane’s release, and have already received orders for 1,500 planes, which they hope to deliver by 2019.

How do the Astronauts Sleep in Space….

After months of intense training and a white-knuckled trip through the ozone layer at nine times the speed of a rifle bullet, you can bet that NASA astronauts need to bank some rest.

Space sailors log really long hours throughout their days on tasks that require intense concentration, which is why NASA schedules precisely 8.5 hours of sleep per 24 on deck.

How exactly does ‘nighttime’ play out in space?

Airbus has come up with a crazy way of fitting more people into planes…

The aviation industry is always looking for new ways to get more people into their planes and judging by a new patent filing, Airbus is proposing a pretty radical idea.

The manufacturer of the world’s largest commercial jet, the A380, just filed a patent in Europe for a number of wacky looking seating configurations on its aircraft, creating the potential to jam even more people into planes.

In the patent filing, the company says “in modern means of transport, in particular in aircraft, it is very important from an economic point of view to make optimum use of the available space. Passenger cabins are therefore fitted with as many rows of passenger seats as possible, which are positioned with as little space between them as possible.”

Amongst the range of new configurations is a business class cabin with a mezzanine level.

Passengers on the upper level would have to climb steps to reach their seats. Seats in this configuration would recline flat, allowing passengers to enjoy an airborne version of being in a bunkbed.

Another design shows two passengers seated on a mezzanine, face to face, something which business travellers looking to get work done might find particularly helpful!

 

The patents may be designed to save space but Airbus was also keen to stress that the new seats will provide a “high level of comfort for the passengers using the seat arrangement.”

It also said that the seat configurations could be used on trains and buses. One bonus that might come from such cramped conditions is that air fares could get cheaper.

But no matter how unpleasant these planes might look, it seems unlikely that the designs will ever come into use.

Airbus is well known for filing hundreds of patents per year in order to protect its intellectual property and ensure that competitors like Boeing cannot get the upper hand.

Recent patents filed by the company include a jet that could travel across the Atlantic in only one hour.

IISc Students Design Helicopter Which Derives Power from Its Own Blades. Bag Prestigious Award …..

A team of students from Indian Institute of Science bagged a coveted award at the Student Design Competition conducted by American Helicopter Society International. This is what the students had designed.

This August, four students from Indian Institute of Science, Bangalore, won the ‘Best New Entry – Graduate’ award at the Student Design Competition conducted annually by the American Helicopter Society International.

The challenge was to design a small helicopter that can carry packages weighing up to 10kgs and can deliver them in urban settings.

The eco-friendly aspect of the challenge was that the helicopter should function at a noise level lower than a prescribed limit, with minimal carbon footprint. Team Lakshya, of aerospace engineering department of IISc, came up with two solutions:

  • To deliver lighter packages: A four-blade small helicopter (a quad-rotor, looks like a drone) that derives power from the vibrations of its blades.
  • To deliver heavier packages: A conventional unmanned aerial vehicle

Both the vehicles partly derive power from their blades, thus reducing carbon footprint as compared to helicopters which are fully powered by fossil fuels.

The technology behind using energy from blade vibrations has been developed by the Non Linear Multifunctional Composites Analysis and Design (NMCAD) laboratory of the department of aerospace engineering in IISc. The institute is in the process of getting the technology patented. The team behind the development of this technology was crowned ultimate champion at the 4th edition of UNESCO-Airbus biennial innovation challenge, “Fly Your Ideas (FYI)” at Hamburg, Germany, in June this year.

American Helicopter Society organizes the Student Design Competition in association with other major helicopter companies, and this was the 32nd edition of the competition.

 

“The AHS International annual Student Design Competition challenges students to design a vertical lift aircraft that meets specified requirements, provides a practical exercise for engineering students at colleges and universities around the world and promotes student interest in vertical flight technology,” says that society’s website.

Every year, the organizers choose an open design problem and students have to submit their entries. The jury has academic and well as industry experts.

“It is indeed a proud moment and a wonderful experience to be recognised by the world’s most renowned vertical flight society,” said Rajnish Mallick, a doctoral graduate from IISc, who led Team Lakshya, to The Hindu.

5 Things you Need to know about India’s First Space Observatory…

This mission will study astronomical phenomena, puts India in select group of nations

The Indian Space Research Organisation on Monday successfully launched the Astrosat satellite. Through this launch, India has joined a select group of countries that have their own space observatory satellite.

Here are five things you need to know about Astrosat.

1.
This is India’s first attempt at setting up an observatory in space, a place from where it can study cosmological phenomena.
2.
The mission is aimed at obtaining data that will help in a better understanding of the universe. The mission is to study astronomical phenomena. Astrosat is carrying five payloads, including an ultraviolet imaging telescope.
3.
Astrosat is generally described as India’s version of the Hubble telescope that NASA had put in space in 1990.

But experts say it is not right to call Astrosat India’s Hubble, as the NASA version is 10 times heavier than Astrosat and is said to cost $2.5 billion, while India’s satellite costs around Rs 180 crore.

4.
Astrosat will put ISRO in a very exclusive club of nations that have space-based observatories. Only the United States, European Space Agency, Japan and Russia have such observatories in space..
5.
For the third time an Indian rocket will be launching seven satellites in a single mission. In 2008, ISRO had launched 10 satellites in one go, including India’s Cartosate-2A satellite.

ISRO Creates History. Launches India’s First Space Observatory – ASTROSAT ….

ISRO has successfully launched India’s first dedicated multi wavelength space observatory – ASTROSAT, which is meant to observe distant celestial objects and to gain a more detailed understanding of our universe.

Right after celebrating the completion of Mangalyaan’s first year in the Martian orbit, the Indian Space Research Organization has set yet another milestone today. ISRO got its name etched in the scientific history of the India with the launch of the country’s first dedicated multi wavelength space observatory – ASTROSAT.

A 50-hour countdown for the launch of the scientific satellite began at 8 am on Saturday.

And the final launch took place at 10 am today from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. –

ASTROSAT is an astronomy observatory, a place from where India can study different cosmological phenomena. It is meant to observe distant celestial objects and to gain a more detailed understanding of our universe.

The speciality of ASTROSAT is that with just a single satellite, it enables simultaneous multi-wavelength observations of many astronomical elements.

The 1,513-kg satellite, estimated to have cost around Rs. 180 crore, was launched by PSLV-C30 into a 650 km orbit inclined at an angle of 6 degree to the equator. This is the 31st flight of India’s Polar Satellite Launch Vehicle (PSLV), and six small satellites of three foreign countries have also been launched along with ASTROSAT. It is for the first time that the PSLV launcher, which has lifted 45 small and mid-sized foreign satellites till date, is carrying four US Nano satellites. The other satellites are from Canada and Indonesia.

The spacecraft control centre at Mission Operations Complex (MOX) of ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bangalore will manage the satellite during its mission life.

While most of ISRO’s spacecraft are for specific applications such as communication, Earth observation and navigation, this is one among the few scientific satellites launched by the country. According to the official release by ISRO, missions of ASTROSAT include the following:

  • To understand high energy processes in binary star systems containing neutron stars and black holes
  • Estimate magnetic fields of neutron stars
  • Study star birth regions and high energy processes in star systems lying beyond our galaxy
  • Detect new briefly bright X-ray sources in the sky
  • Perform a limited deep field survey of the Universe in the Ultraviolet region

ASTROSAT has five payloads which rely on the visible, Ultraviolet and X-rays coming from distant celestial sources.

They will gather data for the better understanding of various astrophysical processes occurring in our universe, and will send it to the ground station at MOX. This data will then be processed and distributed by the Indian Space Science Data Centre (ISSDC). While most scientific satellites can observe a narrow range of wavelength band, ASTROSAT will observe universe in the optical, ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum. All major astronomy institutions and some universities in India will also participate in these observations.

The types and functions of the payloads as described by ISRO are as follows:

The Ultraviolet Imaging Telescope (UVIT, capable of observing the sky in the Visible, Near Ultraviolet and Far Ultraviolet regions of the electromagnetic spectrum

Large Area X-ray Proportional Counter (LAXPC, is designed for study the variations in the emission of X-rays from sources like X-ray binaries, Active Galactic Nuclei and other cosmic sources.

Soft X-ray Telescope (SXT) is designed for studying how the X-ray spectrum of 0.3-8 keV range coming from distant celestial bodies varies with time.

Cadmium Zinc Telluride Imager (CZTI), functioning in the X-ray region, extends the capability of the satellite to sense X-rays of high energy in 10-100 keV range.

Scanning Sky Monitor(SSM),is intended to scan the sky for long term monitoring of bright X-ray sources in binary stars, and for the detection and location of sources that become bright in X-rays for a short duration of time.
