Abstract North Korea has made significant strides in its attempt to acquire a strategic nuclear deterrent. In 2017, it tested intercontinental ballistic missiles (ICBMs) and completed series of test explosions. These may provide with the technical foundation deploy nuclear-armed ICBM capable striking United States. The Ground-based Midcourse Defense (GMD) missile defense system is intended dete...

The gross features in the distribution of stars as well as warm (T > ∼ 100 K) interstellar dust in the Galactic disk have been investigated using the recent mid infrared survey by Midcourse Space Experiment (MSX) at 8, 12, 14 & 21 µm bands. An attempt has been made to determine the location of the Galactic mid-plane at various longitudes, using two approaches : (i) fitting exponential functions...

Abstract The James Webb Space Telescope (JWST) is NASA’s flagship mission successor to the highly successful Hubble Telescope. It an infrared observatory featuring a cryogenic 6.6 m aperture, deployable Optical Element (OTE) with payload of four science instruments (SIs) assembled into Integrated Science Instrument Module (ISIM) that provide imagery and spectroscopy in near-infrared band betwee...

■ The Midcourse Space Experiment satellite was launched in 1996 into an 898-km altitude, near sun-synchronous orbit. A principal sensor on board the satellite is the Space-Based Visible (SBV) sensor, a visible-band electro-optical camera designed at Lincoln Laboratory to perform the first technical and functional demonstration of space-based space surveillance. The principal task of the SBV sen...
