India’s second lunar probe, Chandrayaan-2, faces possible launch delays
India’s second lunar probe, Chandrayaan-2, faces possible launch delays due to limitation in their rocket engine capabilities.

At last! The ISS is to finally going to get an experimental centrifuge.
I have studied at length all the research done on all the space station ever launched, from Skylab, all the Russian Salyut stations, Mir, and now ISS, and from I could tell, only once was a centrifuge experiment put in space, by the Russians. Though the centrifuge was small and the results inconclusive, they suggested that even the addition of a truly miniscule amount of force could significantly mitigate the effects of weightlessness on plants and materials.
To finally get an experimental centrifuge on ISS is wonderful news. In order to build an interplanetary spaceship as cheaply and as efficiently as possible using centrifugal force to create artificial gravity we need to know the minimum amount of centrifugal force we need. Less energy will probably require less complex engineering, which should also require less launch weight to orbit, lowering the cost in all ways.

The solar scientists at the Marshall Space Flight Center significantly downgraded their prediction today for the upcoming solar maximum.
Unfortunately, the Marshall scientists don’t archive their previous predictions, merely changing the text of their webpage periodically. However, I have archived most of these predictions as they have changed. Here they are:

An evening pause: How things will be built and manufactured in the future, on Earth and in space, though in space they probably won’t use concrete.
Making buildings invisible to earthquakes.
The manslaughter trial of six scientists and one government official continued yesterday in Italy over their reassurances to the public prior to a deadly earthquake in 2009.
Guido Bertolaso, former head of the Department of Civil Protection and De Bernardinis’s direct superior, had not been indicted and was originally expected to appear as a witness. But a few weeks ago a wiretap revealed that he had apparently set up the meeting to convey a reassuring message, regardless of the scientists’ opinion. He also seemed to be the source of the “discharge of energy” statement. He thus found himself under investigation and, at the beginning of the hearing, he was officially notified that he too may soon be formally indicted for manslaughter.
Bertolaso was asked by the prosecutor to explain that telephone conversation. He defended himself by saying that by defining the meeting as a “media move”, he was not trying to downplay risks but rather to put some order into the contradictory information that was reaching the citizens in those days. In particular, he referred to Giampaolo Giuliani — a laboratory technician and amateur seismologist who was alarming the population with claims that a major shock was coming — and to a newspaper article that had misquoted some Civil Protection experts and stated that the shocks would soon be over. The meeting, he said, was meant to make clear that both were wrong and that no deterministic prediction could be made. [emphasis mine]

For its second attempt to launch the Orbiting Carbon Observatory, NASA has finally decided to dump Orbital Sciences’ Taurus XL rocket, the same rocket that failed on two previous launch attempts.
The decision to change launch rockets will delay launch by at least a year. Still, this is better than losing a third research satellite.
