NASA Plans Airships, Floating City for Manned Venus Mission


NASA_HAVOC
NASA To Explore Venus

The team at NASA have always looked forward in expanding their horizons and have now come up with a project to explore the planet Venus. A research project has been unveiled by NASA’s Space Mission Analysis Branch, proposing to send astronauts to Venus speculating that the `lighter than air’ pods would be hovering above the clouds that would be housing the explorers.NASA has revealed that they intend sending astronauts to explore Venus with inflatable air born habitats and a movie together with an image has been published on a NASA website portraying a conceptual design for inflatable silver blimp type air balloons for the purpose of living and working which would be accommodating the two astronauts for a period of one month in the planet Venus atmosphere.

A statement from NASA’s Space Mission Analysis Branch – SMAB, states that “a recent internal NASA study of a High Altitude Venus Operational Concept – HAVOC, has led to the development of an evolutionary program for the exploration of Venus with focus on the mission architecture and vehicle concept for 30 day crewed mission to Venus’s atmosphere. A lighter than air vehicle can carry either a host of instruments and probes or a habitat and ascent vehicle for a crew of two astronauts to explore Venus for up to a month”.

Atmosphere Relatively Benign

Mission to the planet Venus, according to the American space agency would need less amount of time when compared to a similar manned mission to Mars. It is also considered that the mission would be much simpler since the atmosphere of the planet is relatively benign together with similar gravity, pressure and density to Earth. According to SMAB, the atmosphere of planet Venus seems to be an exciting destination for further scientific study as well as future human exploration and the main technical challenges for the mission would include performing the aero capture manoeuvres at Venus as well as Earth, inflating and inserting airship at Venus together with protecting the solar panels and the structure from the sulphuric acid in the atmosphere.

Need Advanced Technology/Further Refinement

NASA has also stated that there would be a need of being advanced in technology as well as further refinement of the proposed venture before its implementation. Presently, there has not been any successful manned mission to any planet though the moon seems to be the only natural satellite that man has ever set his foot on.

NASA had disclosed earlier this year, that it had managed in creating the first 3D printed object in space together with a machine on the International Space Station and is now a 3D printing tools for use on the station. Several designers have created concepts for extra-terrestrial adventures which include a London firm Priestmangoode, who had designed a capsule which would be floating tourists to the edge of space together with ZA Architects, who intend sending robots to Mars to build caves for the purpose of human habitation. Stay tuned for more interesting updating details coming up for future exploration on the planet Venus.





Online Timesheet Management

Timesheet
Technology has been playing a very important role in our daily functions of life, which saves on time and effort and can be performed with ease and comfort.

The Real Cybercrime Geography


Cybercrime
According to cyber experts, the recent cyber attack on Sony Pictures was due to digital infiltration of North Korea. In digital world things change very rapidly and due to that spin doctors of North Korea stated in quick response that they didn’t hack the server of Sony Pictures and some of cybercrime experts from U.S. also telling the same that North Korean propagandists can be right. As per the evidence, which represented by FBI, it’s clear that incriminate hackers were working for the government organizations, communist, but still U.S experts stated that these proof are not just enough to blame Pyongyang.


According to Sam Glines, CEO of Norse (a cyber security firm), “According to data collection which was based on forensic evidence, it’s clear that North Korea is not accountable for any type of hacking activity or on initiating the attack on Sony Pictures”. All the hackers must be busy because thousands of information gathered from Sony Picture’s servers, which they released after few hours. All the leaked information was related to cast salaries, film’s budget, taxes of actors and actresses with little known fact that Kevin Federline act for a cameo appearance in $5,000. We all know that country North Korea is still on war with America, but America was never on the radar for computer attacks. So, who was responsible for cyber attack on Sony Picture’s? India? Russia? or Iran and Iraq? In future the answer can be the surprise.

According to Symantec there are 20 countries in world that can responsible for cyber attacks and the list was generated on following factors; malicious code rank, malicious computer activity, phishing, spam zombies rank, attack origin and bot rank. The top five countries according to survey were the U.S.A., China, Germany, Britain and Brazil, whereas; the in the list bottom three are Argentina, Australia and Israel, however; South Korea came in at No. 14, Russia at No. 12, and the fact is that North Korea didn’t make it to enter into top 20.

If you will say just gather 10 American computer experts on coffee table and soon the talk will turn into hacking and cybercrime, but it’s not true, however the Russians have been active in cybercrime and cyber-hacking from past few decades as they are also playing the vital role in cybercriminal world. In present if you own money, and want to hack into PC or mobile, so all you need to place an order or buy a program for a cyberattack to get someone’s personal information or swipe financial or banking information. IN western firms the online banking fraud and credit card information theft is normal, now the main question is “If the Russians are so good, so why they just landed up on rank at No. 12?

Fraud-Proof Credit Cards Through Quantum Physics


Credit_Cards
Researcher at the Eindhoven University of Technology and the University of Twente have come up with a secure way to authenticate he credit cards, IDs and biometrics with quantum cryptography. It is the method of quantum secure authentication through optical keys, which consist of sending a beam of light at cards with very special paint and later the reflection will use as the authentication mechanism.

It involves the coherent states of light with photon number, which means there are a lot of spaces for the bouncing of photons, as it can be more than one space on same time, so whenever the credit cards reflect the beam with specific paint there will be more dots or points of light will sent back than there are photons and it is well known that attackers won’t have enough amount of data to measure the entire pattern.

Research Details: 

This solution is very easy in implementation with current technology and it doesn’t depend on claim of researcher and stored data. In the process of research experts used the cards coated with millions of nano-particles in the form of white paint, which help to bounce the incoming light particles. In research experts have used the two spatial light modulators, a photon detector and a pinhole. In the process one of SLM have transformed incoming light on to desired challenge wave-front to sent it on the card and the reflected response with challenge were stored in a database.

In process each response of pair will requires 20 KB of memory or for 2,500 pairs it will require 50-MB of database and correct response were sent to a lens behind, which will be behind second SLM that focused them onto a photon detector to authenticate them.

System details: 

High spatial dimension states with photons are the main challenges for system. The created patterns will depend on the challenge as well as the position of the paint particles. In experiment each challenge was described by a 50 x 50 binary matrix, where every element corresponding to a phase was either 0 or Pi. As per the lead researcher, “All we need to make the illumination pattern complex to make sure that number of photons are lower than the number of pixels, which appears in image.

The first SLM will transform the wavefront of an incoming plane into a selected challenge wavefront at random from of database. As the challenge is created dynamically and exists only after the transformation, so it cannot be intercepted. All the response will be recorded in a phase-sensitive manner.

Nothing is impossible: 

When it comes to the failure of experiment, so system can be brake with the help of passive linear optical system, which can automatically transforms the any challenge into the correct response and it is very close to make the physical copy of key. So for full proof security must be done in the patterns of layers as different patterns require different level of security.

Launch of New Orion Spaceship Has NASA Flying High


Orion_Spaceship
Looking back at the space shuttle days, the recent impending debut of Orion spacecraft has left NASA on a high note. According to the sources, shuttle veterans are expected to be leading the charge in two-orbit, 4½-hour test flight, which is meant to shake out the capsule, before the astronauts can climb aboard. The destination at the moment has been said to be Mars. As per the lead flight director stationed at Mission Control in Houston, Mike Sarafin, they never felt this kind of feeling since the closure of the shuttle program. This is a very proud moment for them, as they will be launching an American spacecraft from the United States of America’s soil, which is meant for starting something new and explore some of the dark secrets of the space.

The launch of new Orion spacecraft: 

The spacecraft is expected to fly farther than any human-rated spacecraft (this is since the Apollo moon program) and it will aim at a distance of 3,600 miles, which is 14 times higher than the International Space Station and it is expected that altitude will provide a momentum for a 20,000-mph and 4,000-degree entry over the Pacific. The most vital part of the test flight is called the "trial by fire” by NASA, which is the 11 short minutes to splashdown. The heat shield at Orion's base is the largest of its kind ever built, which is at 16.5 feet across.

If sources have to be believed, nearly 650 journalists and around 26,000 guests are expected at the Kennedy for the sunrise launch. The space center press site was packed with many out of station reporters who have not been since the last shuttle flight in 2011. The capsule's inaugural run was put on par with that of the formative steps of Apollo and the space shuttles by the NASA's Orion program manager, Mark Geyer. He stated that they are starting a new mission, which is at the region on the moon and looking forward to something beyond than that. As per Jeff Angermeier, “Ground support mission manager from Florida's Kennedy Space Center, everybody can feel the buzz as this is a very exciting time for them”.

According to Charles Bolden Jr, Administrator of NASA, “In past 40 years, it will be the first time when America is going to launch a spacecraft meant to carry humans beyond low-Earth orbit. That’s what makes it a big deal”. Before 2012, Orion is not planning to carry any astronauts. NASA wants to test some of the most critical parts of the capsule as it will be travelling through the high-radiation Van Allen belts surrounding Earth and engineers are looking forwards to check on the effect on the on-board computers.

As if now the spacecraft will be hoisted by Delta IV rocket but for the next flight in 2018, it will use mega-rocket which is still under development. The spacecraft without any humans has taken some of the stress off the NASA scientists, as they are still trying to overcome the October's explosion moments of the commercial rocket, which was carrying supplies for the International Space Station.
