Things to know: Atlas V prepared for launch from Cape Canaveral





A second plant expansion system, named a Advanced Plant Habitat, will join a float on an Atlas V rocket and transport to a International Space Station to boost a bargain of flourishing plants in space.

An Atlas V rocket stands prepared during Cape Canaveral Air Force Station for a Tuesday morning blastoff of a Cygnus upholder unfailing for a International Space Station.

The 194-foot United Launch Alliance rocket, that rolled to a pad during Launch Complex 41 early Monday morning, is scheduled for liftoff at 11:11 a.m. Weather is 90 percent “go” for a window that closes during 11:41 a.m.

What’s on board?

Orbital ATK’s Cygnus upholder is packaged with some-more than 7,600 pounds of scholarship experiments, reserve and load for a organisation of a ISS.

“We have a far-reaching operation of support apparatus that’s going to be headed to hire to support a scholarship that’s adult there already, though also to deliver code new capabilities,” pronounced Tara Ruttley, associate scientist for a ISS program, during a prelaunch news discussion during Kennedy Space Center. 

The Advanced Plant Habitat, a new KSC experiment, is a minifridge-sized plant cover that will be means to grow larger, some-more nutritionally unenlightened plants that could one day be consumed by astronauts on deep-space missions. Also on house are experiments that could urge chemotherapy treatments for cancer and magnetized collection for easier facsimile of Earth-like experiments.

Cygnus will also take 38 CubeSats, that are miniaturized satellites designed for investigate purposes, to a hire for deployment during a after time.

Remembering John Glenn

Orbital ATK named a Cygnus a S.S. John Glenn in respect of the first American wanderer to circuit Earth, who died final December.

“I feel like we’re bridging history,” pronounced Vern Thorp, module manager for blurb missions during United Launch Alliance. “John Glenn flew on an Atlas rocket in 1962 when he became a initial American to circuit a Earth and right now we’re scheming Atlas to start drifting astronauts again in a nearby destiny as partial of NASA’s Commercial Crew Program.”

Weather status: excellent

Atlas V is approaching to safe off a pad into transparent skies interjection to a 90 percent possibility of auspicious weather.

“This time of year is generally unequivocally auspicious for launch operations,” pronounced David Craft, a continue officer with a Air Force’s 45th Weather Squadron, during the news conference. “It’s no difference for this week.”

A slight possibility of cumulus clouds is a usually intensity concern. Conditions are only as auspicious for a backup launch time of 10:48 a.m. Wednesday.

Third launch of Cygnus from Florida

Tuesday’s launch will be Cygnus’ third moody from Florida on ULA’s “workhorse” Atlas V rocket.

The spacecraft, formerly launched from a Space Coast in 2015 and 2016, transitioned to rising on Atlas V rockets after a 2014 blast of an Orbital ATK Antares rocket during Wallops Island, Virginia.

ULA is now on a 71st altogether launch of Atlas V and a 36th in a 401 pattern that is rising Tuesday.

“That 401 pattern has unequivocally turn a Atlas V workhorse,” Thorp said. “That sold pattern has launched about half of a Atlas V missions over a years.”

The launch was behind from Mar due to hydraulics leaks on a upholder and belligerent support equipment.

George Diller’s swansong

One of NASA’s many famous voices will call “Liftoff!” for a final time on NASA TV when a Atlas V and Cygnus set sail.

George Diller, a open affairs deputy during Kennedy Space Center for 37 years and longtime countdown commentator on NASA TV, skeleton to retire during a finish of May.

A 68-year-old Titusville proprietor whose credits embody job a final space convey launch in Jul 2011, Diller has not wanted to pull courtesy to his departure.

But during the press conference, Frank Culbertson, a former NASA wanderer who is now boss of Orbital ATK’s Space Systems Group, publicly thanked Diller for his service.

“A real, loyal fan of a space program, though also a genuine contributor,” Culbertson said. “So George, appreciate we for everything.”
