The anti-satellite missile the Soviet Union designed for one of its early space stations

Link here. Apparently a prototype was actually flown in 1975 on the second successful Soviet space station, Salyut 3, a military mission. A more sophisticated version was never flown when the Soviet’s cancelled their military space station program. However, its design was most fascinating:

[L]ittle is known about the specifications and operation of the system, but, according to the Head of Science and Research Center at NPO Mashinostroenia Leonard Smirichevsky, who introduced the weapon, the vehicle’s grenade-like solid propellant charges doubled as engines! RussianSpaceWeb.com’s 3D recreation of the displayed variant established that it held 96 casings with solid propellant arranged in a globular fashion like the petals of a dandelion around a central combustion chamber. Upon their ignition, the chambers/grenades might have fed hot propulsive gas into a single or multiple combustion chambers at the center of the contraption, producing either the main thrust and/or steering the vehicle. When the missile reached the proximity of the target, according to its guiding radar, the entire vehicle would explode and the small solid chambers would eject under their own propulsive force in every direction acting as shrapnel.

The missile had a flight range of about 70 miles, and was designed to destroy any hostile satellite or spacecraft that approached the military station.

Giant iceberg breaks off from Antarctica

We’re all gonna die! A giant section of the Antarctic ice shelf, about the size of the state of Delaware, has finally broken off from the main ice cap.

The Science article immediately tries to tie this event to global warming, as articles in this pro-global warming journal are always eager to do. The problem is that there is no way to really do that, as the author himself is forced to admit.

Climate change has a new poster child: a massive iceberg the size of Delaware—one of the largest ever recorded—that early this week calved off Larsen C, the largest remaining ice shelf off the Antarctic Peninsula, scientists announced today. Although researchers cannot explicitly connect the calving event to warming air or water, those monitoring the event are now concerned that the entire shelf, after shedding more than 12% of its area, could follow the fate of its more northern peers, Larsens A and B, which collapsed entirely in 1995 and 2002, respectively.

The Antarctic icecap has been growing in recent decades. Just because a big piece broke off this week tells us nothing about the overall global climate. Furthermore, take a look at the map at the link. On the scale of the entire Antarctica icecap this iceberg is actually only a tiny piece. Such calving events are actually the normal process that occurs at the icecap, and every scientist who studies this subject knows it. Like a glacier, the icecap accumulates snow and ice in its center, which slowly flows outward to the sea, where it eventually breaks off to rejoin the Earth’s normal water cycle. There presently is little evidence that more ice is exiting the icecap than is accumulating at its center.
