NASA’s first asteroid sampling spacecraft, OSIRIS-REx, arrived at the Kennedy Space Center in Florida on Friday, May 20. The spacecraft is set to undergo a series of tests and final preparations to ready it for a September launch to an asteroid, boosted from the Earth atop a United Launch Alliance (ULA) Atlas V 411 rocket. At Kennedy, OSIRIS-Rex will be put through a spin test, solar array release test, electrical system testing, and propellant loading.

Sending human astronauts to Mars is a dream shared by many, but there are still challenges to overcome and the question of just how to accomplish it is a subject of intense debate. Some supporters advocate sending a mission directly to Mars, while others think that returning to the Moon first, for potentially beneficial training, is the way to go. Indeed, former astronaut James Lovell, who flew on two trips to the Moon, has also called for a return to the Moon first. NASA itself has stated its desire to send a crewed mission to a nearby asteroid first, instead of the Moon, going a bit farther into space than the Moon as its idea of preparation for the much longer journey to Mars. A major problem has been that NASA has still not set a firm timetable for such a mission; it wants to go to Mars, but the steps to achieving that goal are still unclear.
Now, the House Appropriations Committee has spoken on the issue in a new report and has made changes in the budget for fiscal year 2017, calling for NASA to abandon its asteroid idea and send astronauts back to the Moon first, before going to Mars.

For the 25th time in a little under six years, the roar of a Falcon 9 rocket’s Merlin-class engines is expected to echo across Cape Canaveral Air Force Station, Fla., on Thursday, 26 May, delivering another payload towards space. Liftoff of the Upgraded variant of the SpaceX booster—equipped with improved Merlin 1D+ engines, structural enhancements to its airframe and benefiting from a “densified” cryogenic-loading protocol—is scheduled to occur from the Cape’s Space Launch Complex (SLC)-40 at 5:40 p.m. EDT Thursday. The relatively spacious, two-hour “launch window” is due to close around 7:40 p.m.
A customary Static Fire Test of the nine Merlin 1D+ engines of the Upgraded Falcon 9’s first stage was successfully conducted on Tuesday evening. “Static Fire complete in advance of Thursday’s launch,” tweeted SpaceX at 10:31 p.m. EDT Tuesday. In addition to transporting the heavyweight Thaicom 6 communications satellite to Geostationary Transfer Orbit (GTO), SpaceX will attempt another landing of the Falcon 9 first-stage hardware on the deck of the Autonomous Spaceport Drone Ship (ASDS) in the Atlantic Ocean.

DIA briefings arranged by Gen. “Davy” Jones as part of Aviation Week’s deal not to publish KH-11 details revealed the Soviets had begun development of a space shuttle that ultimately flew only once—unmanned— in November 1988. Credit: Energia
Editor’s note: This month Aviation Week and Space Technology magazine, where our U.S. Military Space reporter Craig Covault spent nearly 40 years, is celebrating its 100th anniversary. Since Covault provided decades of award winning coverage, the current editors asked that he write a piece for the Aviation Week anniversary issue detailing the process behind two particular scoops that have become legend at AWST. The story is reproduced here with permission along with two corrections that have come to light.
On March 20, 1978, Aviation Week & Space Technology revealed that the Soviet Union was secretly developing its own reusable space shuttle. The article, complete with details on the Soviet shuttle’s design characteristics, was a scoop picked up by media around the globe. What readers do not know, however, is the revelation’s connection to another Cold War blockbuster written 14 months earlier, but not published, after a plea from the acting chairman of the Pentagon’s Joint Chiefs of Staff.

Twenty years ago this week, six men orbited Earth aboard Shuttle Endeavour on one of the most complex research flights ever conducted in the program’s 30-year history. With such a large number of payloads aboard, it was imperative for the STS-77 crew—Commander John Casper, Pilot Curt Brown, and Mission Specialists Andy Thomas, Dan Bursch, Mario Runco, and Canada’s Marc Garneau—to begin activating as many experiments as possible on the first day of their 10-day flight. As described in yesterday’s AmericaSpace history article, STS-77 was tasked with a multitude of experiments in the commercial Spacehab-4 laboratory and the deployment and retrieval of as many as four free-flying satellite payloads. Launch was originally targeted for 16 May 1996, but was pushed back to the 19th, since the earlier date was not available to NASA on the Eastern Range schedule. The crew had been training for the mission for almost a year, having been assigned in June 1995, and took their seats aboard Endeavour for an early-morning liftoff at 6:30 a.m. EDT.
“Really an amazing and wonderful experience,” was the opinion of first-time flier Andy Thomas, an Australian-born U.S. astronaut, who was seated on Endeavour’s flight deck for ascent. “I could look out the overhead windows with a wrist-mirror. I could see the flame in the flame trench, prior to liftoff; I could see the flash of the [Solid Rocket Booster] ignition; and then feel the lurch as we were accelerated upwards.”

From a mountaineering perspective, Earth doesn’t present much of a challenge when compared to other planetary bodies in the Solar System. Mount Everest, Earth’s tallest mountain whose peak reaches 8.9 km above sea level, may seem like a towering giant from a terrestrial standpoint, but when put in context to the mountains and ridges that dominate the surfaces of some of our Solar System’s planets and moons, it feels more like a modest hill.

Early on 20 May 1996, NASA astronaut Mario Runco, Jr., grappled SPARTAN-207—a small, free-flying spacecraft, equipped with a very unique experiment—and lifted it from Shuttle Endeavour’s payload bay with the Canadian-built Remote Manipulator System (RMS) mechanical arm. Together with his five crewmates, Runco had launched just 24 hours earlier, kicking off the 10-day STS-77 mission. And on STS-77, the frequent-flying SPARTAN would undertake its most ambitious exercise yet. Runco released the satellite on time at 7:29 a.m. EDT, into orbital darkness, after which Commander John Casper maneuvered Endeavour to a distance of about 820 feet (250 meters).
Once there, Casper held his ship’s position for about an hour, before conducting a partial flyaround, to a point directly “above” the satellite. Next, he began an 80-minute period of station-keeping to observe a quite remarkable experiment: an experiment with potentially enormous benefits for a range of applications, from space radar to mobile communications, from astronomy to Earth observations, and from environmental research to the analysis of soil moisture and salinity. In fact, STS-77—which was in orbit 20 years ago, this week—set the space shuttle’s myriad capabilities to work and served as a critical pathfinder for future research aboard the International Space Station (ISS).

The New Horizons mission to Pluto has been nothing less than incredible, giving us our first close-up views of this enigmatic dwarf planet and its moons. But the show isn’t over yet, as the New Horizons team is now planning for its next encounter with another Kuiper Belt Object (KBO) in 2019. But even before then, the spacecraft has been busy observing other smaller objects, and has now collected the first science data on one of them, called 1994 JR1.

Having circled hundreds of miles above Earth, a pair of NASA spacefarers with a personal affinity for the word hundred were this weekend inducted into the Astronaut Hall of Fame (AHOF) at the Kennedy Space Center (KSC) in Florida. Four-time flier Brian Duffy, who commanded the shuttle’s hundredth voyage in October 2000, and five-time veteran Scott Parazynski, who flew the mission actually designated “STS-100” in spring 2001, were honored by their peers and the public for making significant contributions to the space program. Over the course of their astronaut careers, Duffy and Parazynski totaled nine shuttle missions between March 1992 and November 2007, featuring rendezvous, docking, spacewalking, scientific research, visiting Russia’s Mir space station, and building the International Space Station (ISS). All told, the pair flew three times apiece on shuttles Discovery, Atlantis, and Endeavour and spent close to a hundred days—98.5 days, to be exact—in space.

The Gemini IX crews consisted of Elliot See (front left) and Charlie Bassett (front right) and their backups, Tom Stafford and Gene Cernan. The deaths of the prime crew on 28 February 1966 forced Stafford and Cernan into their shoes, but was not the end of their misfortunes. On 17 May 1966, they also lost their rendezvous target, the Gemini-Agena Target Vehicle (GATV). Photo Credit: NASA
Fifty years ago, this week, it seemed that Project Gemini’s recent spell of tragedy and misfortune was nearing its end. After a spectacular run of five successful missions in 1965—which included America’s first spacewalk and saw the United States move ahead of the Soviet Union with the longest human space mission yet attempted, as well as accomplishing rendezvous between two orbital vehicles for the first time—Gemini seemed to be smoothly clearing the milestones, ahead of Project Apollo. Then, in February 1966, the Gemini IX crew was killed during training and, a few weeks later, the Gemini VIII astronauts came close to losing their lives after accomplishing the first docking in space. With the Gemini IX backup crew of Tom Stafford and Gene Cernan therefore pushed into the shoes of the prime crew, hopes were high that they would launch on 17 May 1966, for an ambitious three-day mission of rendezvous, docking, scientific experiments, and spacewalking.
