Welcome to this week's issue of The Space Review:


On Hubble's 25th, looking at the next 25 years
---
NASA celebrated last week the 25th anniversary of the launch of the Hubble Space Telescope, looking back on the scientific accomplishments of that famous space telescope. Jeff Foust reports on what the next 25 years in space astronomy might look like beyond Hubble.

Commercial Lunar Transportation Services: a speculation
---
There remains interest in carrying out human missions to the surface of the Moon, even though that is not an official goal of the Obama Administration. Anthony Young discusses how a commercial model for lunar transportation, based on the COTS and commercial crew programs, might be the most cost-effective, and perhaps the only, way to carry out such missions.

Humans to Mars: further delay undermines support
---
Recent proposals have offered missions architectures to get humans to the vicinity of Mars, if not necessarily on the surface of the planet, by some time in the 2030s. Joe Webster argues that to maintain public support, those timelines need to be accelerated with a modest amount of additional funding.

Battle of the Collossi: SLS vs Falcon Heavy
---
Many in the space community like to debate the merits of two heavy-lift vehicles under development, NASA's SLS and SpaceX's Falcon Heavy. Dale Skran offers a tale of the tape of the two heavyweights, comparing their planned capabilities and costs.

If you missed it, here's what we published in our previous issue:


A five-year checkup
---
Last week marked the fifth anniversary of President Obama's speech at the Kennedy Space Center, outlining his vision for the future of NASA's space exploration efforts. Jeff Foust examines the progress NASA has made in various aspects of that vision, and the controversies that linger to this day.

Phobos indeed
---
Recent studies and recommendations by advisory groups have raised interest in a mission to Phobos as a precursor to a Mars mission, perhaps in place of NASA's Asteroid Redirect Mission. Louis Friedman notes that such interest in Phobos missions is not new, and may also not be that effective for long-term human Mars exploration.

The attraction of space social events
---
Social events like Yuri's Night are increasingly popular, but are they an effective way to increase awareness of and interest in space? Alan Steinberg goes over the results of a survey that explored that issue.

Moon and Mars are physically and fiscally feasible
---
In recent weeks, plans for human Mars missions have been criticized for both their technical and financial feasibility. John Strickland argues that these critiques don't hold up when Mars architectures are revised to take advantage of reusable launch systems.

Review: Terrestrial and Extraterrestrial Space Dangers
---
Space can be a dangerous place, and knowing the various risks and their odds can be vital for space exploration. Jeff Foust reviews a book that tries to do just that, but falls far short of the mark.
