== Reviewer A:  ==

Table 1 lists [[spacecraft]]. The Helios spacecraft were built by Germany, and both SOHO and Ulysses are ESA spacecraft. The missions are collaborative projects with NASA, but the spacecraft are certainly not NASA spacecraft. I've corrected these in Table 1.

Solar Sentinels:

"Sentinels is the NASA component of the joint NASA–ESA Heliophysical Explorers (HELEX) mission that also includes ESA’s Solar Orbiter."

My understanding is that the HELEX program (which was the basis of the Solar Orbiter instrument AO) is "dead". Solar Orbiter is not discussed anymore in the context of flying with the Sentinels but with Solar Probe+. From the website of the 3rd Solar Orbiter Workshop: http://solarorbiter3.oato.inaf.it/

"The aim of the conference is to highlight the uniqueness of the scientific objectives of the Solar Orbiter mission, selected for the ESA Horizon 2000 plus Programme, in the scenario of the new and future missions foreseen for solar physics investigations and in particular in connection with the NASA Solar Probe mission." 

and from the program:

14:30 NASA’s heliophysics programme – Science and missions
Dick Fisher
15:00 NASA’s Solar Probe Plus – Science goals and status
Lika Guhathakurta
15:20 Synergies between Solar Probe Plus and Solar Orbiter
Dave McComas
15:40 Orbit synchronization enabling two-point in-situ measurements
from Probe and Orbiter
Adam Szabo

No word from Sentinels. 

I would recommend that the authors check with NASA HQ about the status of Solar Sentinels and update the article accordingly.

Otherwise very nice overview!
