It’s Dead, Jim! ISRO Gives Up on Lunar Lander, Rover

Well, it’s not the famous winter of Game of Thrones, but the 14-day lunar night has arrived where India’s Vikram lander and Pragyan rover made what IRSO officials have called a “hard landing” two weeks ago with no communication between them and ground controllers.

Since neither vehicle was designed to survive the frigid temperatures of the lunar night, the Indian space agency has called it a day in a rather bare bones announcement.

India’s Vikram Suffered “Hard Landing” on Moon

ISRO’s Chandrayaan-2’s orbiter has spotted the Vikram lander in the surface of the moon, but it’s not looking very good.

“Yes, we have located the lander on the lunar surface. It must have been a hard landing,” Sivan told PTI….

Asked if the lander was “damaged” during the “hard landing”, Sivan said: “That we do not know.”

Sivan had said on Saturday that the space agency would try to establish link with the lander for 14 days and reiterated on Sunday after it was located on the lunar surface by Chandrayaan-2’s on-board cameras that those efforts would continue.

Fourteen days is the length of a lunar day. The lander and the Pragyan rover it carried are not designed to survive the frigid cold of the lunar night.

The Vikram lander stopped communicating with ground controllers as it descended toward a landing near the moon’s south pole. ISRO said the loss of communications occurred less than 2 km (1.25 miles) above the surface.

Chandrayaan-2 is India’s second mission to the moon and first attempt to land a payload on the surface.

ISRO has provided an update on its failed attempt to place Chandrayaan-2’s Vikram lander and Pragyan rover on the moon:

“The Vikram Lander followed the planned descent trajectory from its orbit of 35 km to just below 2 km [1.25 miles] above the surface. All the systems and sensors of the Lander functioned excellently until this point and proved many new technologies such as variable thrust propulsion technology used in the Lander.

The success criteria was defined for each and every phase of the mission and till date 90 to 95% of the mission objectives have been accomplished and will continue contribute to Lunar science , notwithstanding the loss of communication with the Lander.

ISRO stressed that the Chandrayaan-2 Orbiter continues to circle the moon and is expected to return a wealth of scientific data:

India’s Moon Landing Possibly Failed

India’s first attempt to place a lander and a rover on the surface of the moon might have failed on Friday.

ISRO officials say that descent operations of Chandrayaan-2’s Vikram lander were normal until it reached 2.1 km above the landing spot near the south pole before all telemetry ceased. ISRO said it is evaluating the data.

It is not clear whether the lander crashed along with its Pragyar rover or if there was a communications glitch. The Chandrayaan-2 orbiter is functioning normally, ISRO said.

France, India to Develop Ship Tracking Satellite Constellation

PARIS (CNES PR) — On the occasion of the state visit to France of India’s Prime Minister Narendra Modi, an agreement signed by CNES President Jean-Yves Le Gall and K Sivan, Chairman of the Indian Space Research Organisation (ISRO), was officially announced to start development and production of a constellation of satellites on which studies have been underway since President Emmanuel Macron’s state visit to India in March 2018.

This constellation carrying telecommunications (AIS*) and radar and optical remote-sensing instruments will constitute the first space-based system in the world capable of tracking ships continuously. The satellites will be operated jointly by France and India to monitor ships in the Indian Ocean. The system will cover a wide belt around the globe, benefiting a broad range of French economic interests. With a revisit capability making it possible to task acquisitions several times a day, it will also be able to detect oil slicks and trace their origin.

The Vikram Lander successfully separated from Chandrayaan-2 Orbiter at 1315 Hrs IST today (September 02, 2019). The Vikram Lander is currently located in an orbit of 119 km x 127 km. The Chandrayaan-2 Orbiter continues to orbit the Moon in its existing orbit.

The health of the Orbiter and Lander is being monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru. All the systems of Chandrayaan-2 Orbiter and Lander are healthy.

The next maneuver is scheduled tomorrow (September 03, 2019) between 0845-0945 hrs IST

Bengaluru, India (ISRO PR) — Lunar Orbit Insertion (LOI) maneuver was completed successfully today (August 20, 2019). The duration of maneuver was 1738 seconds beginning from 0902 hrs IST. With this, Chandrayaan-2 was successfully inserted into a Lunar orbit. The orbit achieved is 114 km x 18072 km.

Following this, a series of orbit maneuvers will be performed on Chandrayaan-2 spacecraft to enable it to enter its final orbit passing over the lunar poles at a distance of about 100 km from the Moon’s surface.

Subsequently, the lander will separate from the Orbiter and enters into a 100 km X 30 km orbit around the Moon.  Then, it will perform a series of complex braking maneuvers to soft land in the South polar region of the Moon on September 7, 2019.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru. All the systems of Chandrayaan-2 are healthy.

The next Lunar bound orbit maneuver is scheduled tomorrow (August 21, 2019) between 1230-13:30 hrs IST.

The Times of India reports that ISRO is asking commercial companies to build its workhorse booster for the first time:

In a major push for PM Narendra Modi’s Make-in-India initiative, the Indian Space Research Organisation (Isro) has finally invited Indian companies to build five Polar Satellite Launch Vehicles (PSLVs).

Confirming this on Friday, Isro chairman K Sivan told TOI: “At this moment we have called for an EOI (expression of interest), and it is not open for any foreign firm. Isro has been considering this for a while, and we think this will boost the Make-in-India initiative of the government.”
