Earth-sized exoplanet in the habitable zone discovered

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), researchers have discovered an Earth-sized planet that lies in its star’s habitable zone. The planet (TOI 700 d) is about 1.2 times the size of Earth and receives from its star 86% of the energy that the Sun provides to Earth and so considered to be in the … Continue reading Earth-sized exoplanet in the habitable zone discovered

ISRO officially confirms locating Vikram lander, silent on whether it is intact

ISRO has posted on its website saying: “Vikram lander has been located by the orbiter of Chandrayaan-2, but no communication with it yet.” It does not say if it is intact or broken into pieces. In a first direct official confirmation, the Indian Space Research Organisation (ISRO) on Tuesday (September 10) morning tweeted and posted … Continue reading ISRO officially confirms locating Vikram lander, silent on whether it is intact

ISRO: Chandrayaan-2’s Vikram lander came tantalisingly close to creating history

While it is indeed unfortunate that Vikram lander failed to safely touchdown, it is important to remember that ISRO was attempting powered landing for the first time. To put it in perspective, there have been 38 attempts so far by other countries to land a rover on the Moon and have succeeded only a little … Continue reading ISRO: Chandrayaan-2’s Vikram lander came tantalisingly close to creating history

Chandrayaan-2: GSLV Mark III-M1 vehicle reduces number of orbit-raising exercises, saves fuel

The GSLV Mark III-M1 vehicle launched Chandrayaan-2 satellite in the Earth Parking Orbit with an apogee (farthest distance from the earth) of 45,475 km, which is about 6,000 km more than originally envisaged. As a result, the number of orbit-raising manoeuvres needed to take the satellite to the highest orbit has been reduced from six … Continue reading Chandrayaan-2: GSLV Mark III-M1 vehicle reduces number of orbit-raising exercises, saves fuel

Chandrayaan-2 soars to the Moon

Earlier this year, China landed a robotic spacecraft on the far side of the Moon, which is a first ever attempt by any country. Now, India is attempting a similar feat — to land its rover Pragyan in the Moon's South Polar region, a place that no country has attempted so far. A decade after … Continue reading Chandrayaan-2 soars to the Moon

Surveillance from the sky using RISAT-2B satellite

RISAT-2B satellite launched on May 22 will use microwave radiation for crop monitoring, forestry and flood mapping. The satellite can image during day and night and under almost all weather conditions including cloud cover. It can detect objects with dimensions of as little as a metre, making it ideal for military surveillance. With the successful … Continue reading Surveillance from the sky using RISAT-2B satellite

ISRO sets the bar high by launching 104 satellites in one mission

The Indian Space Research Organisation boosted its reputation further when it successfully launched a record 104 satellites in one mission from Sriharikota on Wednesday by relying on its workhorse Polar Satellite Launch Vehicle rocket. An earth observation Cartosat-2 series satellite and two other nano satellites were the only Indian satellites launched: the remaining were from … Continue reading ISRO sets the bar high by launching 104 satellites in one mission

How ISRO plans to launch a record 104 satellites in one go in February 2017

The Indian Space Research Organisation (ISRO) will set a record when it launches 104 satellites in one go on a single rocket in the first week of February. Explaining how all the satellites will be placed in orbit, Dr. K. Sivan, Director of the Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, says: “The satellites will be … Continue reading How ISRO plans to launch a record 104 satellites in one go in February 2017

IIT Madras researchers develop an optical system to detect algal blooms

An integrated optical system capable of detecting and monitoring algal (or phytoplankton) blooms both spatially and temporally in coastal and open ocean waters has been developed by a team of researchers at the Indian Institute of Technology (IIT), Madras. Very soon, the Hyderabad-based Indian National Centre for Ocean Information Services (INCOIS) will begin using the … Continue reading IIT Madras researchers develop an optical system to detect algal blooms

Editorial: Houston, we have a litter problem

The change in the orientation and orbit of the 17-cm glass-sphere Russian nano-satellite BLITS that was noticed in early February was caused by a January 22 collision with a piece of China’s Feng Yun 1C weather satellite; Feng Yun 1C was intentionally blown up in the 2007 anti-satellite weapon test by China. That irresponsible act … Continue reading Editorial: Houston, we have a litter problem
