Nasa to Fly Dragonfly a Drone-like Lander on Titan to Find the Traces of Life

Our solar system and space beyond have always been the topic of interest for the humans. For a few years now, most of the big space agencies are exploring the Martian surface, and now, the American space organisation, NASA has decided to explore ‘Titan’, one of the 62 moons of Saturn.

Nasa has revealed that it will send a drone-like lander, named Dragonfly, on the surface of Titan, capable of flying 8 or 9 miles in an hour. The Dragonfly will be a 10-foot-long, and 10-foot-wide dual-quadcopter, similar to the size of the Mars rover and will be a look-alike of a giant drone.

Since the Titan has the best environment for flying rather than walking or rolling over the surface, the drone is specifically designed to hop and fly over it. The gravity of Titan is equal to one-seventh of the Earth’s gravity and has a far thicker environment than that of the Earth, providing the suitable conditions for Dragonfly to fly in it.

According to Nasa, the drone will be exploring the surface of Titan and will discover places for landing over it. It will be collecting samples for research, observe the weather conditions and will notify the agency if it finds something unusual. The drone is equipped with drills and probes, to investigate the surface and has got cameras embedded to it, through which will it will be sending HD pictures of the objects found on Titan back to Nasa. Dragonfly will spend about 16 days at a single place and examine the environment. After 16 days, it will move further with the help of the eight rotors it possesses.

Elizabeth Zibi Turtle, the lead investigator of the mission, said during the announcement that Nasa will launch Dragonfly in 2026, which will land on the dune-filled equatorial region of Titan through a parachute. The drone will be back to Earth in 2034.

Nasa has already touched down the surface of Titan with the Huygens probe via the Cassini mission earlier, but according to Turtle, with Dragonfly, it will be a more in-depth mission and will discover major alien things on it.

“We know that Titan has rich organic material, very complex organic material on the surface. There’s energy in the form of sunlight, and we know there’s been water on the surface in the past. These ingredients, that we know, are necessary for the development of life, as we know it is sitting on the surface on Titan. They’ve been doing chemistry experiments, basically, for hundreds of millions of years, and Dragonfly is designed to go pick up the results of those experiments.” said Turtle.

With the rivers and other organic material found on Titan, it has always been considered as a prototype of Earth, before life on Earth. So the interest of the researchers has always been to find the traces of life over it.

Team Indus: An Indian space technology startup in the race to land on moon

Team Indus a Bangalore, India based technology startup is one of few companies in the world and only company from India that have ventured into highly costly and research intensive aerospace industry. Team Indus (Axiom Research Labs) founded by Rahul Narayan, Dilip Chabria, Indranil Chakraborty, Sameer Joshi and Julius Amrit has plans to land on moon. ISRO a Govt. of India organization is the only agency in India that works in aerospace field and has been working on a mission to mars called Chandrayaan since 2003.  There are only three countries in world that have soft-landed on moon (China, USSR & US). Soft landing means lading with controlled speed without any damage to spacecraft and surface.

This Indian space startup is participating in Google Lunar XPRIZE competition and working on a spacecraft that will be capable of landing on the moon along with a rover that will explore moon. Google will be offering $30 million as  prize money to the winners of this competition (cost of this kind of project is way hire than prize money offered by Google). Team Indus was one of five teams selected to compete in the Milestone prizes and they won $1M as a Milestone prize for their landing technology. To win the contest participating team has to land a robot on the moon, cover 500 meters over the lunar surface, and send data and pictures back to the earth.

Team Indus started working in 2010. The team which had no experience in space technology worked hard for three years and came up with first design in 2013. Adimurthy, a retired  ISRO scientist rejected their design after first review in 2013. Indus team worked hard and was ready with a new propulsion system in a year.

Propulsion technology innovation

Since propulsion technology used by other countries is highly confidential and inaccessible, Team Indus decided to design their own propulsion system. Team Indus is going to use a propulsion systems that  has never been used before for such critical space mission. They are using a combination of small fixed thrust engines and produce the variable thrust effect using control algorithms. So what other space organizations have been doing with hardware, Team Indus is trying to do with software algorithms.

Team Indus is being led by Rahul Narayana along with more than 20 ISRO scientist. Team Indus with more than 100 employees has secured funding to the tune of $35 M from Pallav Nadhani (Fusion Charts), Subrata Mitra & Shekhar Kirani (Accel Partners), Sharad Sharma (former Yahoo India R&D head), Vivek Raghavan (chief product manager of UIDAI), Pallaw Sharma (director of analytics at Microsoft),  Bala Parthasarthy(AngelPrime angel investors), Sunil Kalra(entrepreneur & investor) and Paras Chopra.

Team Indus has acquired a launch vehicle (PSLV) from ISRO on commercial rates for sending their spacecraft and rover to moon from Sriharikota in 2017. It would be interesting to see who lands on moon first, ISRO, Team Indus or Elon Musk‘s SpaceX which has already started booking for earth to moon flight.
