Rosetta has now completed its three largest rendezvous burns as it approaches ever closer to comet 67P/Churyumov-Gerasimenko. Beginning on July 2, Rosetta will now conduct weekly burns, through August 6. Meanwhile, the cometary activity of April and May has quieted again, leaving the comet looking smaller than it did before.

The LightSail team has found potential workarounds to solve the spacecraft’s boom deployment problems, but more analysis lies ahead.
The Senate and House have both agreed to increase NASA's budget to $17.9 billion, but they have very different ways of spending that money. The House bill would add additional funding to almost every category of the Planetary Science budget and would greatly strengthen NASA’s program of planetary exploration. The Senate bill would add substantial funds to the Mars program but pay for this by cuts to other portions of the planetary budget.
Will New Horizons have a mission after Pluto? Ground-based searches have failed to turn up anything that New Horizons can reach. Now Hubble is joining the search, but time is running out: a discovery must be made within the next two months.

Curiosity has been busy. The rover has traveled more than half a kilometer since my last update, making steady progress beyond the Kimberley toward Murray Buttes. There hasn't been much time for science, but they sneaked in an observation of a Mercury transit across the sun, and a neat MARDI video of the rover driving.

This week the OSIRIS-REx team gathered at the Lockheed Martin facility in Denver to perform a “Design Reference Mission (DRM)” walkthrough. The DRM is basically the battle plan for OSIRIS-REx for accomplishing our goal of returning pristine samples from asteroid Bennu.
India's Mars Orbiter Mission has accomplished its second trajectory correction manuever, a small rocket burn lasting only 16 seconds. Meanwhile, NASA's MAVEN is testing out its instruments, with one obtaining "first light" on Mars.
The LightSail team continues to investigate problems with the spacecraft’s boom deployment system that postponed a flight system test earlier this month.
