It will be a TSTO vehicle whose first stage, like SpaceX’s, will be a five-engine semi-cryo cluster. This will have a modular structure. With one core semi-cryo stage, we can simply go on adding any number of strap-ons, and different payload requirements can be met. The second stage will be a cryo-stage. After the first stage is separated, it can be recovered in sea, like SpaceX has done. </span></blockquote>

<div style="text-align: justify;">
<span style="font-family: Verdana, sans-serif; font-size: large;"><span style="background-color: white;"><span style="line-height: 23px;">On Earth, observing space is a challenge due to the presence of atmosphere that either blocks or distorts most part of the electromagnetic spectrum (including infrared and visible light). So there is a practical upper limit to the quality of observation. </span></span></span><span style="background-color: white; font-family: Verdana, sans-serif; font-size: large; line-height: 23px;">To counter this, scientists created space borne telescopes that are not affected by all the atmospheric distortions. But they also come with their own limitations due to size restrictions driven by launch rockets and their availability on short notice. </span></div>
<div style="text-align: justify;">
<span style="font-family: Verdana, sans-serif; font-size: large;"><span style="background-color: white; line-height: 23px;">With SOFIA, NASA has aimed to achiceve the best of both worlds by using aircraft with a much bigger telescope to reach edge of the atmosphere for distortion less observations. Also, it will also be able to monitor transient events from anywhere in the world on a short notice. </span></span></div>

<span style="background-color: white; line-height: 22.399999618530273px;"><span style="font-family: Verdana, sans-serif; font-size: large;">NASA has released image of a galaxy about 23 million light years away that is currently a site of impressive, ongoing fireworks. This galactic light show involves a giant black hole, shock waves and vast reservoirs of gas.</span></span></div>
<div style="background-color: white; border: 0px; line-height: 22.399999618530273px; margin-top: 1em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;">
<span style="font-family: Verdana, sans-serif; font-size: large;">The concerned galaxy is NGC 4258, also known as M106. Its is a spiral galaxy similar to our Milky Way, but with a difference that it has two extra spiral arms that glow in X-ray, optical and radio light. </span></div>
<div style="background-color: white; border: 0px; line-height: 22.399999618530273px; margin-top: 1em; outline: 0px; padding: 0px; text-align: justify; vertical-align: baseline;">

<span style="font-family: Verdana, sans-serif;"><span style="font-size: large;">The anomalous arms are seen in this new composite image of NGC 4258, where X-rays from NASA’s Chandra X-ray Observatory are blue, radio data from the NSF’s Karl Jansky Very Large Array are purple, optical data from NASA’s Hubble Space Telescope are yellow and infrared data from NASA’s Spitzer Space Telescope are red.</span><span style="font-size: large;">A new study made with Spitzer shows that shock waves, similar to sonic booms from supersonic planes, are heating large amounts of gas – equivalent to about 10 million suns. What is generating these shock waves? Researchers think that the supermassive black hole at the center of NGC 4258 is producing powerful jets of high-energy particles. These jets strike the disk of the galaxy and generate shock waves. These shock waves, in turn, heat the gas – composed mainly of hydrogen molecules – to thousands of degrees.</span><span style="font-size: large;">The Chandra X-ray image reveals huge bubbles of hot gas above and below the plane of the galaxy. These bubbles indicate that much of the gas that was originally in the disk of the galaxy has been heated and ejected into the outer regions by the jets from the black hole.</span></span></blockquote>

ISRO is utilizing various NAL facilities to perform tests on scaled model of RLV-TD. Dynamic tests were performed by NAL using forced oscillation rig to determine the pitch/yaw damping characteristics of a scaled model of RLV-TD configuration. This will help in building flight stability augmentation system for both ascent and descent configuration of RLV-TD. These tests were carried out in the 1.2 m trisonic wind tunnel facility. </div>

The detail of this massive pyramid is fantastic and you can see two other rectangle structures on it. The asteroid is probably not for mining as much as used as a tiny space station. An asteroid that size and a structure that size is a bit out of proportion...so this cannot be a mining facility. This massive structure is meant to be hidden on this small asteroid, so it is probably monitoring planets as it passes them without any primitive life discovering them...however, India was on top of it and caught it quickly. Awesome work India. SCW</span></span></blockquote>

I am gonna leave it to you to make final judgement!!</span></div>

OCO-2 will be collecting space-based global measurements of atmospheric CO2 with the precision, resolution, and coverage needed to characterize sources and sinks on regional scales. OCO-2 will also be able to quantify CO2 variability over the seasonal cycles year after year. It will help in enhancing the current understanding of the global carbon cycle and of the sustainability of natural carbon sinks like oceans. </span><br />

Equipment bay was designed to carry NGC&C electronics and later modified to also carry micro and nano sats. AINS is based on optical sensors and was tested for navigation performance during the flight time. AINS most probably will be part of LVM3.</span></div>

<br />
<div style="text-align: justify;">
ISRO recently commissioned a new facility called Cabin Environment Simulation System (CESS) under the Human Space Flight Program. CESS will be used for test and evaluation of space modules under regulated environmental conditions that may arise during various phases of manned mission.<br />
<br />
<a name='more'></a><br /></div>
<div style="text-align: justify;">
CESS consists of a horizontally mounted cylindrical chamber of 2100mm diameter and 1200mm cylindrical length with two torispherical dome enclosures–with opening at one end. It has been designed for maintaining an internal vacuum level of 10-2 m.bar and insulated such that the outside surface temperature remains within 40 deg C when the internal maximum temperature is at 100 deg C. This large main chamber has been provided with a pumping system to maintain any pressure level between 1.3 mbar to 1200 mbar inside the chamber. </div>

<br />
<div style="text-align: justify;">
As mentioned previously on this <a href="http://antariksh-space.blogspot.sg/2012/06/isro-considering-rendezvous-and-docking.html">blog</a>, ISRO has been working on a rendezvous and docking (RVD) experiment mission involving two IMS (Indian Micro Satellite) series spacecrafts. ISAC, a ISRO centre, has been involved in developing navigation and guidance algorithm for RVD. In this experiment, two IMS Spacecrafts, one designated as target and the other designated as chaser, will be launched by a PSLV launcher into two slightly different orbits. There will be no communication link between the target and chaser during the far range rendezvous phase in which relative separation between the spacecrafts will be around 50km to 5km range and this phase will be a ground guided phase. In the docking phase of the mission, docking sensors such as Laser Range Finder during the relative separation of 5 km to 0.25km, Docking Camera during the relative separation of 300m to 1m ,Visual Camera for real time imaging during the relative separation of 1m to docking will be used respectively.</div>
<div style="text-align: justify;">
<br /></div>
For the purpose of testing and verification of vision based docking algorithms before a real world implementation is carried out, ISRO has developed a 3D simulation environment that is being used to simulate docking phase of the mission. A snap of the simulation is presented in the Figure below.<br />

<div style="text-align: justify;">
<b>Targeted Applications of RVD: </b>RVD technology is one of many enabling technologies for ISRO's human space flight program. Another promising application of this technology will be increasing age of ISRO's satellites like that from IRS, INSAT and IRNSS systems. RVD technology will allow a resupply (fuel, power pack etc) spacecraft to dock with a satellite in orbit and allow for replenishment of fuel and power pack, thereby increasing satellites age. To facilitate this, as per my research, ISRO has been designing its newest satellite bus called I-6K, which is a unified bus with modular design ,multi EV panels and scalable structure (Bus module & payload module). A modular design will allow easy and fast replacement of bus module in the orbit by the resupply space craft. The resupply spacecraft might itself be a new bus module (with fuel, power pack etc.) that will dock with the payload module in the orbit after the old bus module undocks. </div>
