Chandrayaan-2 Completes a Year Around the Moon
One-year completion of Chandrayaan-2 Lunar orbit insertion (August 20, 2019) Chandrayaan-2 completes a year around the Moon The Moon provides the best linkage to understand Earth’s early history and offers an undisturbed record of the inner Solar system environment. It could also be a base for future human space exploration of the solar system and a unique laboratory, unlike any on Earth, for fundamental physics investigations. In spite of several missions to the Moon, there remains several unanswered questions. Continued high resolution studies of its surface, sub-surface/interior and its low-density exosphere, are essential to address diversities in lunar surface composition and to trace back the origin and evolution of the Moon. The clear evidence from India’s first mission to the Moon, Chandrayaan-1, on the extensive presence of surface water and the indication for sub- surface polar water-ice deposits, argues for more focused studies on the extent of water on the surface, below the surface and in the tenuous lunar exosphere, to address the true origin and availability of water on Moon. With the goal of expanding the lunar scientific knowledge through detailed studies of topography, mineralogy, surface chemical composition, thermo-physical characteristics and the lunar exosphere, Chandrayaan-2 was launched on 22nd July 2019 and inserted into the lunar orbit on 20th August 2019, exactly one year ago. Though the soft-landing attempt was not successful, the orbiter, which was equipped with eight scientific instruments, was successfully placed in the lunar orbit. The orbiter completed more than 4400 orbits around the Moon and all the instruments are currently performing well. -

During the decade from 1989–1998, NASA used two types of launch systems, one consisting of several families of expendable launch vehicles (ELV) and the second consisting of the world’s only partially reusable launch system—the Space Shuttle. A significant challenge NASA faced during the decade was the development of technologies needed to design and implement a new reusable launch system that would prove less expensive than the Shuttle. Although some attempts seemed promising, none succeeded. This chapter addresses most subjects relating to access to space and space transportation. It discusses and describes ELVs, the Space Shuttle in its launch vehicle function, and NASA’s attempts to develop new launch systems. Tables relating to each launch vehicle’s characteristics are included. The other functions of the Space Shuttle—as a scientific laboratory, staging area for repair missions, and a prime element of the Space Station program—are discussed in the next chapter, Human Spaceflight. This chapter also provides a brief review of launch systems in the past decade, an overview of policy relating to launch systems, a summary of the management of NASA’s launch systems programs, and tables of funding data. The Last Decade Reviewed (1979–1988) From 1979 through 1988, NASA used families of ELVs that had seen service during the previous decade. -
Transmittal of Geotail Prelaunch Mission Operation Report
National Aeronautics and Space Administration Washington, D.C. 20546 ss Reply to Attn of: TO: DISTRIBUTION FROM: S/Associate Administrator for Space Science and Applications SUBJECT: Transmittal of Geotail Prelaunch Mission Operation Report I am pleased to forward with this memorandum the Prelaunch Mission Operation Report for Geotail, a joint project of the Institute of Space and Astronautical Science (ISAS) of Japan and NASA to investigate the geomagnetic tail region of the magnetosphere. The satellite was designed and developed by ISAS and will carry two ISAS, two NASA, and three joint ISAS/NASA instruments. The launch, on a Delta II expendable launch vehicle (ELV), will take place no earlier than July 14, 1992, from Cape Canaveral Air Force Station. This launch is the first under NASA’s Medium ELV launch service contract with the McDonnell Douglas Corporation. Geotail is an element in the International Solar Terrestrial Physics (ISTP) Program. The overall goal of the ISTP Program is to employ simultaneous and closely coordinated remote observations of the sun and in situ observations both in the undisturbed heliosphere near Earth and in Earth’s magnetosphere to measure, model, and quantitatively assess the processes in the sun/Earth interaction chain. In the early phase of the Program, simultaneous measurements in the key regions of geospace from Geotail and the two U.S. satellites of the Global Geospace Science (GGS) Program, Wind and Polar, along with equatorial measurements, will be used to characterize global energy transfer. The current schedule includes, in addition to the July launch of Geotail, launches of Wind in August 1993 and Polar in May 1994. -

Sapphire-Like Payload for Space Situational Awareness Final
Sapphire-like Payload for Space Situational Awareness John Hackett, Lisa Li COM DEV Ltd., Cambridge, Ontario, Canada ([email protected]) ABSTRACT The Sapphire satellite payload has been developed by COM DEV for a Surveillance of Space mission of the Canadian Department of National Defence, which is scheduled to be launched later in 2012. This paper presents a brief overview of the payload, along with the potential for using this optical instrument as a low cost, proven Space Situational Awareness hosted payload on geostationary satellites. The Sapphire payload orbits on a dedicated satellite and hence the payload was not required to actively point. The proposed hosted payload version of Sapphire would be enhanced by incorporating a two dimensional scan capability to increase the spatial coverage. Simulations of the hosted payload version of Sapphire performance are presented, including spatial coverage, approximate sensitivity and positional accuracy for detected resident space objects. The moderate size, power and cost of the Sapphire payload make it an excellent candidate for a hosted payload space situational awareness application. 1. INTRODUCTION The Sapphire payload is described elsewhere [1] and was developed by COM DEV on a moderate budget for MDA Systems Ltd. and the Canadian Department of National Defence and is scheduled to fly in 2012. The Sapphire payload combines the SBV heritage [2] through the telescope design/contractor, with high quantum efficiency CCDs and advanced high reliability electronics. The Sapphire mission [3] was developed by the Canadian Department of National Defence (DND) as part of its Surveillance of Space project. MDA Systems Ltd. was the mission prime contractor, and COM DEV was the payload prime contractor. -

From its first scientific run in 2007, the Virgo detector has constantly been upgraded over the years; since 2017, with the Advanced Virgo project, the detector reached a high sensitivity that allowed the detection of several classes of sources and to investigate new physics. This work reports the Citation: Bersanetti, D.; Patricelli, B.; main hardware upgrades of the detector and the main astrophysical results from the latest five years; Piccinni, O.J.; Piergiovanni, F.; future prospects for the Virgo detector are also presented.
