India's Chandrayaan-2 images Sarabhai Crater
by Staff Writers
New Delhi (Sputnik) Aug 14, 2020

The Digital Elevation Model (DEM) and 3D view of the crater generated using the Fore, Nadir and Aft images from TMC-2 reveals average depth of the crater as ~1.7 km from the raised crater rim and average slope of the crater walls is in the range 25-30 degrees. This Sarabhai crater outer region is dominated by numerous smaller craters of varying diameter distributed over the flat Mare plains, and is devoid of any large crater (diameter >10 km) in its vicinity (~100 km around). The raised rim, the gradient inner walls and the small hummocky floor makes the Sarabhai crater an excellent example to understand the impact processes on the lava filled region of the Moon.

India's soft Moon landing, Chandrayaan-2, failed on 7 September 2019 due to a reduction in velocity beyond the designed parameters. However, its orbiter has continued to perform "as per the design providing valuable scientific data".

India's Space Research Organisation (ISRO) on Wednesday shared images of vast lava plains creating a near flat surface on the Moon, captured by the Terrain Mapping Camera - 2 (TMC-2) on board the ISRO's Chandrayaan-2.

The images were shared on the birthday of Dr Vikram Ambalal Sarabhai, the father of the Indian space programme. The pictures of the Sarabhai Crater on Mare Serenitatis in the northeast quadrant of the Moon show these vast lava plains. Sarabhai was an Indian physicist and astronomer who initiated space research and helped develop nuclear power in the country.

"The Chandrayaan-2 spacecraft was inserted into lunar orbit on 20 August 2019. All eight payloads on Chandrayaan-2 are performing well. The global mapping of lunar surface and polar coverage are being carried out as per the mission plan", ISRO has said.

As per the space agency statement, public release of scientific data from Chandrayaan-2 for global use will begin in October 2020, wherein details for accessing the data will be provided.

While the Chandrayaan-2 failed to make a soft landing on the lunar surface, its orbiter continues to perform "as per the design providing valuable scientific data" and continues sending pictures back to Earth.

It began its voyage on 22 July from the ISRO's spaceport on the eastern coast of Sriharikota in Andhra Pradesh, but lost contact with the ISRO's Earth Station just minutes before the scheduled soft-landing near the Moon's south pole.

Russian Cosmonauts Could Be Going to the Moon Without a Super-Heavy Launch Vehicle
Moscow (Sputnik) Jul 27, 2020
Russian space industry giant Energia is involved in the production of everything from rockets and satellites to space stations and ballistic missiles, and is the prime mover behind the current Russian manned spaceflight programs. Korolev Rocket and Space Corporation Energia has created and patented a means to fly cosmonauts to the Moon and back without an expensive new heavy-launch rocket. "The technical result [of the method] is the possibility of transporting crew between a near-Earth orbi ... read more
