A special issue of the journal “Science” describes an early analysis of data collected by the lander Philae in its descent to the surface of the comet 67P/Churyumov-Gerasimenko. Its mission was short and ESA engineers can’t get a stable contact after those of recent weeks but the data collected were very helpful. Another very interesting study just appeared about the interaction of the comet with the solar wind.

In recent days, the Mars Rover Curiosity deviated from its programmed route to examine a rock particularly rich in silica. It’s a material composed of silicon and oxygen common in terrestrial rocks in the form of quartz. On Mount Sharp, where Curiosity is working, on its way it took a sample near the area called “Marias Pass”. The results of the analysis were so interesting that the mission team decided to turn it back.
During the weekend the lander Philae resumed communications from the surface of the comet 67P/Churyumov-Gerasimenko. It’s been almost exactly seven months since Philae ran out of battery power and, because its position didn’t allow it to recharge them using its solar panels, had gone into hibernation. Now ESA is preparing new plans to try to make the most of the period in which the comet will be close enough to the Sun to provide the energy needed for Philae to work.
NASA has confirmed that the Mars Rover Opportunity’s flash memory has been successfully reformatted so that it doesn’t use a corrupted memory bank. The agency also announced that yesterday Opportunity completed the marathon traveling for 42.195 kilometers (26.219 miles) on Mars. Sure, it took a bit since about two months it celebrated 11 Earth’s years on the red planet but it’s another record for this extraordinary rover.
NASA has confirmed that the Mars Rover Curiosity has returned to work after the problem due to a transient short circuit that happened in late February that convinced mission control to halt its activity. In particular, the robotic arm that that was blocked was finally able to deposit the sample of pulverized rock within Curiosity to proceed to its analysis.
The Mars Rover Curiosity’s protection system blocked its activity on February 27, or sol – Martian day – 911 of its mission. NASA’s Curiosity team left it stationary to avoid the risk that the problem gets aggravated while it was diagnosed.
