NASA WALLOPS FLIGHT FACILITY, VA – An Orbital ATK Antares rocket successfully blasted off this morning, Sunday, Nov. 12, from the eastern shore of Virginia on a NASA contracted mission bound for the International Space Station (ISS) carrying a Cygnus cargo ship loaded with nearly 4 tons of vital science and supplies.
NASA WALLOPS FLIGHT FACILITY, VA – The Orbital ATK Antares rocket is all set for a breakfast time blastoff from the commonwealth of Virginia to the International Space Station for NASA with a Cygnus cargo freighter named in honor of Gene Cernan, the last man to walk on the Moon.
A new research study by a group of astronomers, based on observation using the VLTI, has created the most detailed map of a star other than the Sun.

NASA is targeting mid-October for the ‘Return to Flight’ launch of the upgraded Orbital ATK Antares rocket on a cargo mission to resupply the International Space Station (ISS).
In light of the grounding of the SpaceX Falcon 9 and Dragon cargo flights following the catastrophic Sept.1 launch pad disaster, this Orbital ATK mission becomes more critical than ever to keep that station stocked and fully operational for the resident crews.
NASA and Orbital ATK announced that the re-engined Antares will launch during a five-day launch window that opens no earlier than October 9-13, 2016 on the OA-5 Cygnus cargo mission from the Mid-Atlantic Regional Spaceport at Wallops Island on Virginia’s Eastern shore.
“A more specific date will be identified upon completion of final operational milestones and technical reviews,” according to statements from NASA and Orbital ATK.
If Antares launches on Oct. 9, liftoff is set 10:47 p.m. EDT and becomes progressively earlier on succeeding days. The launch time moves up to 9:13 p.m. EDT on Oct. 13.
If the launch takes place during this window, it will mark the first truly nighttime launch for Antares from Virgina.
“The arrival and berthing of Cygnus to the International Space Station will be determined by the exact launch date and in coordination with other space station activities,” says NASA.
For the OA-5 mission, the Cygnus advanced maneuvering spacecraft will carry approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for the International Space Station (ISS).
Under the Commercial Resupply Services (CRS) contract with NASA, Orbital ATK will deliver approximately 28,700 kilograms of cargo to the space station. OA-5 is the sixth of these missions.

Conjunctions of bright planets make for jewelry in the sky. This week, get ready for some celestial shimmer. If you’ve been following the hither and thither of Mars and Saturn near Antares this summer, you know these planets have been constantly on the move, creating all kinds of cool alignments in the southern sky.
On Tuesday night (August 23) the hopscotching duo will fall in line atop Antares in the southwestern sky at nightfall. Mars will sit just 1.5° above the star and Saturn 4° above Mars. Viewed from the Americas and Europe, the line will appear slightly bent. To catch them perfectly lined up, you’ll have to be in central Asia on the following evening, but the view should be pleasing no matter where you live.
Nice as it is, the Mars-Saturn-Antares lineup is only the warm-up for the big event: the closest conjunction of the two brightest planets this year. On Saturday evening, August 27, Venus and Jupiter will approach within a hair’s breadth of each other as viewed with the naked eye — only 0.1° will separate the two gems. That’s one-fifth of a full moon’s width! While Mars and Saturn will be a snap to spot low in the southwestern sky during their conjunction, Venus and Jupiter snuggle near the western horizon at dusk.
To make sure you see them, find a place in advance of the date with a wide open view to the west. I also suggest bringing a pair of binoculars. It’s so much easier to find an object in bright twilight with help from the glass. You can start looking about 25 minutes after sunset; Venus will catch your eye first. Once you’ve found it, look a smidge to its lower right for Jupiter. If you’re using binoculars, lower them to see how remarkably close the two planets appear using nothing but your eyeballs. Perhaps they’ll remind you of a bright double star in a telescope or even the twin suns of Tatooine in Star Wars.
Have a small telescope? Take it along — Jupiter and Venus are so close together that they easily fit in the same high magnification field of view. Jupiter’s four brightest moons will be on display, and Venus will look just like a miniature version of the waxing gibbous moon. Rarely do the sky’s two brightest planets nearly fuse, making this a not-to-miss event.
If cloudy weather’s in the forecast that night, you can still spot them relatively close together the night before and night after, when they’ll be about 1° or two full moon diameters apart. I get pretty jazzed when bright objects approach closely in the sky, and I’m betting you do, too.
I also don’t mind being taken in by illusion once in a while. During a conjunction, planets only appear close together because we view them along the same line of sight. Their real distances add a dose of reality.
On Saturday evening Venus will be 143 million miles (230 million km) away vs. 592 million miles (953 million km) for Jupiter. In spite of appearing to almost touch, Jupiter is more than four times farther than the goddess planet.
That distance translates to the chill realm of the giant gaseous planets where sunlight is weak and ice is common. Try stretching your imagination that evening to sense as best you can the vast gulf between the two worlds.
You might also try taking a picture of them with your mobile phone. I suggest this because the sky will be light enough to get a hand-held photo of the scene. Photos or not, don’t miss what the planets have in store for earthlings this week.
Orbital ATK announced late Tuesday that the company’s Antares medium-class commercial rocket outfitted with new first stage RD-181 engines has successfully completed a test firing of the powerplants.
The 30-second long static test firing took place at 5:30 p.m. Tuesday evening, May 31, at Virginia Space’s Mid-Atlantic Regional Spaceport (MARS) Pad 0A.
The now revamped launch vehicle – dubbed Antares 230 – has been ‘re-engined’ and upgraded with a pair of modern and more powerful first stage engines – the Russian-built RD-181 fueled by LOX/kerosene.
The engine test was conducted using only the first stage of Antares at the MARS Pad 0A at NASA’s Wallops Flight Facility.
“Early indications show the upgraded propulsion system, core stage and launch complex all worked together as planned,” said Mike Pinkston, Orbital ATK General Manager and Vice President, Antares Program.
“Congratulations to the combined NASA, Orbital ATK and Virginia Space team on a successful test.”
Orbital ATK engineers will now “review test data over the next several days to confirm that all test parameters were met”
If all goes well with the intensive data review, the company could launch Antares as soon as July on its next NASA contracted mission – known as OA-5 – to resupply the International Space Station (ISS).
The test involved firing up Antares dual first stage RD-181 engines at full 100% power (thrust) for a scheduled duration of approximately 30 seconds. Hold down restraints kept the rocket firmly anchored at the pad during the test.
The RD-181 replaces the previously used AJ26 which failed moments after liftoff during the last launch on Oct. 28, 2014 resulting in a catastrophic failure of the rocket and the Cygnus cargo freighter.
The RD-181 flight engines are built by Energomash in Russia and had to be tested via the static hot fire test to ensure their readiness.
“They are a good drop in replacement for the AJ26. And they offer 13% higher thrust compared to the AJ26,” said Kurt Eberly, Orbital ATK Antares deputy program manager, in an interview with Universe Today.
As a result of switching to the new RD-181 engines, the first stage also had to be modified to incorporate new thrust adapter structures, actuators, and propellant feed lines between the engines and core stage structure.
So the primary goal was to confirm the effectiveness of the new engines and all the changes in the integrated rocket stage.
“The successful stage test, along with the extensive testing of each new RD-181, gives us further confidence in the first stage propulsion and in moving forward to launch,” said Pinkston.
“We are now focused on the OA-5 mission and launching the enhanced Cygnus spacecraft to the International Space Station on our upgraded, higher-performing Antares rocket.”
The test used the first stage core planned to launch the OA-7 mission from Wallops late this year.
With the engine test is completed, the OA-7 stage will be rolled back to the HIF and a new stage fully integrated with the Cygnus cargo freighter will be rolled out to the pad for the OA-5 ‘Return to Flight’ mission as soon as July.
“Each of the new flight RD-181 engines has undergone hot fire acceptance testing at the manufacturer’s facility prior to being shipped to Orbital ATK. A certification test series was successfully completed in the spring of 2015 where a single engine was test fired seven times, accumulating 1,650 seconds of test time and replicating the Antares flight profile, before being disassembled for inspection,” said Orbital ATK officials.
