Critical eye: reviews roundup

23:30
In unusually graphic language, Nasa has described the period leading up to next month's landing of its car-sized Curiosity rover on Mars as "seven minutes of terror". In that time, the craft must reduce its speed from 6.1 km per second to make a gentle pin-point landing in Gale crater. To put it as close as possible to the most interesting geology, its target is now a 7km by 20km ellipse at the foot of Mount Sharp which climbs higher than Mont Blanc at the crater's centre.
The bulk of Curiosity's speed is shed using a heat shield, but the craft is still moving at 405 metres per second when it deploys a parachute at a height of 11km. The heat shield then falls away to reveal a descent stage with retrorockets which take over from the parachute at a height of 1.4km and slow the drop to walking pace. Nylon cords then unwind to lower the rover the final 20 metres to the surface. After the cords are severed, the descent stage should veer off to the side to crash out of harm's way
The landing is due at 06:31 BST on 6 August and the challenging sequence of events leading up (or down?) to it must occur entirely automatically. Indeed Mars lies 248 million km or 13.8 light minutes from Earth at the time so those fateful seven minutes will be history for Curiosity before we see them commence. To complicate matters further, a rash of recent problems with Nasa's Odyssey orbiter may mean it is out of position to relay immediate news of the final stages of the descent and touchdown.

World's Third-Largest Spam Botnet Taken Down
You know those tons of spam e-mail you've been getting about fake prescription drugs? A security firm has helped to take down the botnet behind it.Last week, California-based FireEye Malware Intelligence Labs posted on its blog the command and control (CnC) coordinates of the large spam botnet called Grum. "The intention behind this article was not only to share this information for a general awareness," posted the company's Atif Mushtaq, "but also to invite the research community to come forward and take down this spam beast."
'Pulled the Plug' And, he reported, that's what happened, except it wasn't the research community but Dutch authorities who did the deed. Mushtaq reported that they have "pulled the plug on two of the CnC servicers pointing to IP addresses 94.102.51.225 and 94.102.51.227."
He added that these two CnC servers were "responsible for pumping spam instructions to their zombies." In this case, zombies refer not to undead humans, but to undead computers that have been commandeered by malware to resend spam, often without their users' knowledge.
With the servers offline, Mushtaq said, the spam template inside Grum would "soon time out and the zombies will try to fetch new instructions" but would not be able to find them.
But, Mushtaq reported earlier this week, Grum's master CnC servers, based in Panama and Russia, were still up -- so Mushtaq published their information as well. He said that the ISPs handling those servers were contacted with abuse notifications, which were ignored. The botnet could update their zombies from these servers, which would reconstitute the spam network.
'Killing the Beast' Then, on Thursday, Mushtaq posted that the server in Panama had been taken down, the result of the ISP eventually succumbing to community pressure. But then, he wrote, "right in front of my eyes, the bot herders started pointing their...
