Less than six hours after departing Baikonur Cosmodrome in Kazakhstan, Russia’s Progress M-24M cargo craft successfully docked automatically at the Earth-facing (or “nadir”) port of the International Space Station’s (ISS) Pirs module at 11:31 p.m. EDT Wednesday. The spacecraft brought approximately 5,500 pounds (2,500 kg) of equipment, supplies, and experiments to the station’s incumbent Expedition 40 crew—which consists of Russian cosmonauts Aleksandr Skvortsov, Oleg Artemyev, and Maksim Surayev, U.S. astronaut Reid Wiseman, and Germany’s Alexander Gerst, under the command of U.S. astronaut Steve Swanson—and will remain in place through late October. At the time of docking, the ISS and Progress M-24M were orbiting about 259 miles (418 km) over the Pacific Ocean, just off the western coast of South America.

Facing the undeniable reality of a looming communications gap in the 2020s in getting gigabits of precious data back from NASA’s highly productive science armada exploring Mars, the agency is now soliciting information on the potential for utilizing commercial Mars-orbiting telecommunications satellites to provide transmission capabilities for future robotic missions to the Red Planet. And this could also be useful for Humans to Mars missions in the longer term.
“We are primarily interested in communications coverage starting in the 2020s,” Lisa May, Lead Program Executive, Mars Exploration Program at NASA Headquarters, told AmericaSpace exclusively in response to my questions about NASA’s timing and requirements.

The Chandra X-Ray Observatory, NASA’s space telescope which observes the universe using X-rays, has now completed its 15th year of operations, and astronomers are celebrating the anniversary with a series of special images from the orbiting observatory.

The 2009 book Almost Astronauts: 13 Women Who Dared to Dream, written by Tanya Lee Stone, details the struggles encountered by the “Mercury 13,” a group of women pilots subjected to many of the same tests undergone by the Mercury astronauts—but who were denied the right to fly into space based upon their gender. One of the final chapters in the book is entitled, “We Want to See a Woman Driving the Bus, Not Sitting in the Back.”
On July 23, 1999, decades after this intrepid group of women dared to even dream of space, a woman was finally “driving the bus”: An Air Force flyer, Eileen Collins, became the first woman to command a space shuttle on STS-93 (Columbia). Today marks 15 years since that pioneering milestone in spaceflight history.

Sierra Nevada Corporation’s (SNC) Dream Chaser “Dream Team” just keeps on growing, as this week the company announced the expansion of its Dream Chaser Space System’s global partnership to include Asia through a new signed memorandum of “cooperative understanding” with the Japanese Aerospace Exploration Agency (also known as JAXA), who now joins the European Space Agency (ESA) and the German Space Agency (DLR) in SNC’s ever-growing international team.

It was only last week that Space Exploration Technologies (SpaceX) launched the first wave of a next-generation telecommunications satellite fleet to orbit for customer ORBCOMM on the OG-2 mission, but the flight also gave the Hawthorne, Calif.-based aerospace company another opportunity to test out the experimental landing legs they hope will make their Falcon rockets truly reusable, and in doing so SpaceX expects to drive down the cost of launch dramatically by eliminating the need to build a new rocket for every flight.

After three months docked at the International Space Station (ISS), Russia’s Progress M-23M cargo craft—otherwise known as “Progress 55P” in ISS Program-speak—successfully separated from the orbital outpost at 5:44 p.m. EDT yesterday (Monday), bound for several days of “Radar Progress” experiments and ultimately a fiery destruction in Earth’s upper atmosphere on 1 August. In the meantime, its successor, Progress M-24M (or “Progress 56P”), encapsulated within the payload shroud of a mammoth Soyuz-U booster, was rolled out to Site 1/5 at the Baikonur Cosmodrome in Kazakhstan early Tuesday, preparatory to its own launch at 3:44 a.m. local time Thursday (5:44 p.m. EDT Wednesday). Following a well-trodden “fast rendezvous” path, first trialed in August 2012, it is anticipated that Progress M-24M will dock automatically at the Earth-facing (or “nadir”) port of the station’s Pirs module at 9:30 a.m. Baikonur time Thursday (11:30 p.m. EDT Wednesday), a little less than six hours after liftoff.

When the history of our galaxy is written,
and for all any of us know it may already have been,
if Earth gets mentioned at all it won’t be because its inhabitants visited their own Moon.
That first step, like a newborn’s cry, would be automatically assumed.
What would be worth recording is what kind of civilization we earthlings created
and whether or not we ventured out to other parts of the galaxy.
— Michael Collins, “Liftoff: The Story of America’s Adventure in Space” (1989)
Between 60,000 and 100,000 years ago, the first members of anatomically modern humans took their first steps out of the East African savannas, which had been the cradle of human evolution for more than 2.5 million years, to populate the rest of the land of what was an essentially unknown planet. Forty-five years ago this week, humans took their next steps up the evolutionary ladder by walking on the Moon, at a place called Sea of Tranquility, during the Apollo 11 mission in 20 July 1969—the first time that any human beings had ever walked anywhere outside of their own planet. These decisive first steps on another world were equally met with exhilaration, hope, and wonder as well as skepticism, fear, and condemnation. The reasons for these widely varied reactions to humanity’s single greatest achievement ever have been multifaceted and intertwined. The second part of this article examined the American public’s opposition to the Apollo missions to the Moon and toward the space program in general, based on financial arguments pertaining to the former’s supposedly unacceptably high costs. This article will focus on some of the deeper, unconscious emotional, ideological, and cultural reasons behind this opposition. Although the reasons explored here are by no means the only ones that affect space policy decisions, they nevertheless provide a valuable glimpse at the public’s deeper fears regarding space exploration, which in turn influence its attitude toward it.

Apollo 11 command module pilot Michael Collins wrote of his friend and colleague Neil A. Armstrong in his 1974 book Carrying the Fire, “[Armstrong] makes decisions slowly and well … [He] savors them – rolling them around on his tongue like a fine wine and swallowing at the very last moment. (He had twenty seconds of fuel remaining when he landed on the moon.)”
Today, Collins and fellow Apollo 11 crew member Buzz Aldrin remembered this decisive thinker, astronaut, and first-rate test pilot, along with luminaries including Armstrong’s two sons Rick and Mark, former Gemini and Apollo astronaut James A. Lovell, NASA Administrator Charlie Bolden, and Kennedy Space Center (KSC) Director Bob Cabana. In a ceremony held this morning, KSC’s Operations and Checkout (O&C) building was renamed after Armstrong. In addition, guests viewed NASA’s next “giant leap,” the Orion Multi-Purpose Crew Vehicle, being prepared for a scheduled launch in December.
